What do you mean by IPsec? – Explained

by
what is ipsec?
what is ipsec?

IPsec is a set of protocols and technologies designed to secure internet communication. It is also known as Internet protocol security. IPsec is useful in providing security and authentication to the data sent over the internet.

IP packets when sent, do not have any added security to them, and an attacker can easily access the data contained in the IP Packet.

How to secure data using IPsec?

With the help of IPsec, we can secure the data in the following ways: – 

  • Encryption

IPsec encrypts the data, so it becomes unreadable to anyone without the proper decryption key. Hence, it is only readable by the sender and receiver. This makes it difficult for cybercriminals to intercept the data. 

  • Authentication

IPsec also employs authentication mechanisms to confirm the identities of the communicating parties. It ensures that the data is transmitted between the authenticated sender and receiver, which helps to avoid man-in-the-middle attacks. 

  • Security Associations

IPsec establishes security associations (SAs) between two communicating devices. These SAs define the rules and parameters for secure communication, such as the encryption and authentication methods to be used. 

  • Tunnelling

IPsec can create a secure tunnel, known as a VPN (Virtual Private Network), between two devices or networks. This tunnel encapsulates the data, adding an extra layer of security. 

What is IKE?

IKE, also known as Internet Key Exchange, is a protocol used in IPsec which helps establish a secure communication tunnel between devices. It is responsible for exchanging the necessary cryptographic keys and security parameters required for tunnel creation and establishing secure communications.

It helps in negotiating between both parties to agree on how to secure the communication and enables the creation of security associations (SAs) for encrypted and authenticated communications.

How many IKE phases are there?

IKE has two phases, namely:-  

  • IKE Phase 1 

The primary goal of Phase 1 is to establish a secure and authenticated channel for further negotiation. This phase focuses on setting up a secure initial connection between the sender and receiver. Phase 1 is used to create a secure tunnel which we can use in Phase 2. 

  • IKE Phase 2

Phase 2 builds upon the secure channel established in Phase 1 and focuses on negotiating the parameters and keys for securing the actual data traffic. 

What functions does IKE Phase 1 perform?

The following functions are performed in IKE Phase 1: –  

  • Authentication

The parties authenticate each other’s identities using methods like pre-shared keys (PSK), digital certificates, or other authentication mechanisms. 

  • Encryption

Phase 1 can involve the use of encryption to protect the negotiation process itself. 

  • Diffie-Hellman Key Exchange

A secure method for the sender and receiver to agree on shared secret keys is established through the Diffie-Hellman key exchange. 

  • Lifetime and Refreshing

Phase 1 also defines parameters like the lifetime of the negotiation and methods for refreshing keys. 

When Phase 1 is completed, both parties have established a secure communication channel and have derived a shared secret key, known as the IKE Phase 1 key. This key is used in Phase 2 to secure the actual data traffic. 

What functions does IKE Phase 2 perform?

The following functions are performed in IKE Phase 2: –  

  • Selection of Security Policies

The sender and receiver negotiate the specific security policies, including encryption and authentication algorithms, to be used for data traffic. Either AH or ESP IPsec protocol can be used. 

  • Creation of Security Associations (SAs)

One or more SAs are created for each unique combination of source and destination, defining how data should be protected. 

  • Encapsulation Mode

In phase 2, the encapsulation mode is negotiated. The mode can either be tunnel mode or transport mode.  

When Phase 2 is completed, the devices or networks involved have established one or more SAs that define how data will be encrypted, authenticated, and transmitted between them. These SAs govern the secure communication for data packets. 

phase 1 tunnel

Internet Key Exchange is useful to make a secure tunnel but does not encrypt or authenticate the data.  

For this purpose, we use the following two protocols: – 

  • Authentication Header (AH)

AH is a protocol within IPsec that provides data integrity, authentication, and anti-replay protection for IP packets. It does not provide encryption but ensures that the data has not been tampered with during transmission. 

  • Encapsulating Security Payload (ESP)

ESP is another IPsec protocol that provides encryption, data integrity, and optional authentication. It encrypts the entire IP packet, including the payload (data), making it secure. ESP is often used in combination with AH or alone to provide encryption and authentication. 

Both these protocols use two modes: –  

  • Tunnel Mode 
  • Transport Mode 

What is the difference between tunnel mode and transport mode?

The difference between tunnel mode and transport mode is as follows-

  • Transport Mode

In transport mode, only the payload (data) of the original IP packet is encrypted and/or authenticated. The original IP header remains intact. This mode is commonly used for securing point-to-point communication between devices. 

  • Tunnel Mode

In tunnel mode, the complete IP packet, including the IP header and the payload (data), is encapsulated within a new IP packet. This means that the original packet is entirely protected and secured as it travels over the network. Tunnel mode is often used to create Virtual Private Networks (VPNs) between network gateways or between a remote client and a gateway.

What is MPLS & How does it work : Explained

by
The Concept of MPLS
The Concept of MPLS

Internet routing works on packet hopping from one router to another until it reaches the destination address. IP Packet contains no information about the route which it must follow to reach the destination. It just contains the destination IP Address.

In this process, each router that receives the packet has to make an independent forwarding decision for each packet, which it does using the routing table. This process is CPU intensive, seems slow, and decreases the performance of real-time applications like voice.

Also, traditionally to connect different sites of a particular company, we need to add a separate lease line in between the sites which is generally provided by an ISP.

separate lease line

We require another leased line if we further want to connect B and C.

What are the advantages of connecting sites using different lease lines?

Connecting sites using different lease lines has some advantages as follows:  

  1. Secure 
  2. High bandwidth and transmission speed 
  3. More reliable 

What are the disadvantages of connecting sites using different lease lines?

Connecting sites using different lease lines has some disadvantages as follows:

  1. Expensive 
  2. Permanent physical connection 
  3. Not scalable. As the size of a company site increases, more lease lines need to be added. 

What is MPLS?

Multiprotocol Label Switching, also known as MPLS, is a network technology that helps routers make forwarding decisions based on labels instead of IP Addresses. It is a versatile and efficient protocol used to route network traffic.

MPLS operates at Layer 2.5, bridging the gap between traditional Layer 2 (Data Link) and Layer 3 (Network) in the OSI model. This technology is popular and used by organization/ enterprise networks to connect their remote branches. MPLS packet is forwarded based on the MPLS label hence we are not required to open the packet to see the destination address.

This unique positioning enables MPLS to provide a flexible and scalable framework for building private networks over existing infrastructure, creating MPLS VPNs.

Routing using lables
MPLS VPN

With the help of MPLS VPN, connecting different sites becomes comparatively easier and inexpensive since we can use same the MPLS architecture to connect different sites.

MPLS architecture

What is an MPLS Header?

The MPLS header is of 4 bytes, i.e., 32 bits 

  • 20 bits: – Label information field is 20 bits. Labels 0 to 15 are reserved 
  • 3 bits: – Experimental bits are used for Quality of Service (QoS). 
  • 1 bit: – S bit or bottom of the stack. More than one MPLS header can be attached to an IP packet. 

NOTE:

  1. If s bit is 1 implements the header at this point is the last MPLS header 
  2. S bit is 0, MPLS header is not the last header 
  • 8 bits: – Time to live information is 8 bits. TTL value decreases by 1 with each hop. 
MPLS header

What terminologies get used in MPLS?

The terminologies used in MPLS are as follows-

  • P devices

The devices in the provider network that do not directly get connected to a customer site. These devices are in the core network of the service provider. 

  • PE

Provider Edge devices are the devices at the edge of the MPLS network that are directly connected to the customer 

  • CE

Customer Edge devices are the customer network devices that link to the service provider network. CE devices get directly connected to Provider Edge Devices. 

  • LSR

Label switch routers are MPLS-enabled routers that can understand labels. 

  • Ingress LSR

The Ingress label switch router is the router that receives the IP Packer from the Customer Edge router. Ingress LSR attaches the first label to the IP Packet. 

  • Intermediate LSR

These routers are used to swap labels inside the MPLS Network 

  • Egress LSR

These routers remove the label and forward the remaining packet to the Customer Edge router. 

  • Label switched path

LSP is the path that the packet takes in an MPLS network. The first Label Switch Router of the LSP is the ingress LSR, while the last LSR of the LSP is the egress LSR.

What protocol gets used in MPLS?

Since the label is attached to the packet dynamically, there must be some protocol that helps to perform this function. The protocol used in MPLS is as follows-

LDP (Label Distribution Protocol) and TDP (Tag Distribution Protocol) are two routing protocols used in Multiprotocol Label Switching (MPLS) networks to distribute labels and facilitate the establishment of Label Switched Paths (LSPs). 

This protocol automatically generates and exchanges labels between routers. Each router will locally generate labels for its prefixes and then advertise the label values to its neighbours. 

Both protocols function in the same manner, but TDP is Cisco proprietary, and LDP is an open standard protocol. 

LDP

How does MPLS work?

As we have discussed in the case of MPLS, the packet is forwarded with the help of labels instead of IP Addresses. 

Label Switched routers create a local label, and then it distributes this local label to each LDP neighbour. Received labels are called remote labels. LSR stores this local and remote label in a table, known as a label information base (LIB). Out of all the received remote labels, LSR chooses the best path and a remote label associated with it and stores it in a label forwarding information base table (LFIB). 

Instead of performing complex IP header lookups and route calculations for each packet, MPLS routers simply switch packets based on the MPLS labels. This results in faster and more deterministic packet forwarding. 

What is the function of the router enabled with MPLS?

Routers enabled with MPLS perform three functions: – 

  • Push

Add a label to the IP Packet. When a packet enters the MPLS network at the ingress router (the router where it enters the MPLS domain), the router assigns a unique MPLS label to the packet. This label is a short identifier (usually 20 bits) that represents a specific path or route through the network. The assigned label is added to the packet’s header.  

  • Swap

Replace the top label with a different label. As the labelled packet travels through the MPLS network, each router examines the MPLS label in the packet’s header and makes a forwarding decision based on that label. When a labelled packet arrives at an LSR, that LSR looks up its label table and replaces the incoming label with a new label corresponding to the next hop in the Label Switched Path (LSP). All the intermediate LSRs perform Swap.

  • Pop

Removes the label. When this packet reaches a router that is directly connected to the egress LSR, it pops the label and the egress LSR receives an IP packet. 

The egress router then looks up the RIB table and forwards the packet with the help of an IP Address. 

RIB table

What is PHP?

PHP stands for Penultimate Hop Popping, and It refers to the process using which the router just before the final hop (the egress router) in the Label Switched Path, the penultimate hop router has the option to “pop” or remove the MPLS label from the packet and forward it to its destination using regular IP routing.

How does PHP work?

Here’s how PHP works:

When a labelled packet reaches the penultimate hop router (the router just before the egress router), it has already traversed most of the MPLS network with the label intact.

The penultimate hop router knows the egress router and knows that the packet is about to exit the MPLS domain. Instead of forwarding the packet with the MPLS label to the egress router, it performs PHP.

PHP involves removing the MPLS label from the packet and forwarding it based on its original IP header. In other words, the penultimate hop router “pops” the label.

The packet continues its journey to the egress router, which receives it as a regular IP packet, not an MPLS-labeled packet.

What is the purpose of PHP?

The primary purpose of PHP is to reduce the processing load on the egress router. Without PHP, the egress router would need to perform label swapping and forwarding. Since it is the last router of the MPLS network, the packet that It forwards should be an IP Packet, and if PHP is not performed, the egress router has to perform popping of the label as well as an IP lookup to find the destination address of the packet.

This process would be resource-intensive, especially in networks with high traffic loads. By popping the label at the penultimate hop router, the egress router can focus on handling IP packets rather than MPLS-labeled packets.

Red Hat Linux Interview Questions for Experienced Professionals

21. What is meant by hard links?

Hard links are only another term for existent files in the Linux operating system. We can create an infinite number of hard links for each file. They are capable of creating ties for other challenging connections. Hard links don’t reference the pathname; instead, they point to the actual file on the disc.

The ‘Is-I’ command can be used to count all of a file’s hard links.

If you’re wondering how to create hard links using command line, you can use the following command:

$ ln [original filename] [link name]

22. Can you name different types of Linux directory commands and explain each one of them?

There are 5 main types of Linux directory commands you can utilize to work with various files as well as directories. These commands are mentioned below:

  • cd: 

“Change directory” is referred to as “cd.” This command is used to switch the current working directory to the desired directory. This command’s syntax is $ cd path to new directory>.

  • pwd: 

The term “print working directory” (pwd) is used. This command shows the location of the active working directory. This command’s syntax is $ pwd.

  • mkdir: 

“Make directory” is what the acronym mkdir stands for. In Linux, we use this command to create folders.  This command’s syntax is $ mkdir name (and path, if necessary) of new directory>.

  • rmdir: 

“Remove directory” is what rmdir stands for. Any directory on the command line can be removed or deleted with this command. This command’s syntax is $ rmdir name (and path, if necessary) of directory.

  • Is: 

ls stands for “list”. To examine the whole list of files and directories in the currently open working directory, we use this command. This command’s syntax is $ ls.

23. Can you explain the process of creating LVM in Red Hat Cluster?

In order to create LVM in Red Hat Cluster, you can follow the steps mentioned:

  • Run the command “pvcreate /dev/sda2” (#pvcreate /dev/sda2) to achieve this.
  • Once the volume cluster has been built, the real volume must be added to it. 
  • Here, the command “vgcreate VLG0 /dev/sda2” (#vgcreate VLG0 /dev/sda2) could be used. 
  • From the volume cluster, create the required volume right away. 
  • Using the command “#lvcreate -L 1G -n LVM1 VLG0,” In the final stage, users must issue the “mke2f” command (#mke2fs -j /dev/VLG0/LVM1) to build a file system on Sda2.

24. What is meant by pwd command?

The pwd command stands for print working directory command. By using the ‘pwd’ command, you can print the full path name of the working directory right from the root. For example, 

/usr/bin/pwd is a pwd command.

25. What is meant by DASDs?

  • Expanded as Direct access storage devices (DASDs), these are either fixed or removable storage devices. 
  • Most commonly, DASDs are physical devices such as solid state disks or rotating disk drives.
  • DASDs are economical and easy to use. 
  • CD-ROM, DVD, and WORM (write-once read-many) are the types of devices that are not considered as DASDs and are not supported by Logical Volume Manager (LVM).

26. What are the type of remote software users you can use to encrypt the communication?

A dependable remote desktop platform known as the SSH can be used to encrypt the communication. It allows users to manage the Red Hat server without being physically present there. You can use various commands to control it.

27. What is meant by Virtual File Systems?

The v-node interface, sometimes referred to as the virtual file system (VFS) interface, serves as a link between the logical and physical file systems. 

The two main parts of the VFSs are as follows:

  • Logical file system: 

It provides support to the call interface of the system.

  • Physical file system:

It allows the user to manage permanent storage of the data.

So, in other words, the interface between the logical and physical file systems is called the virtual file system interface or the v-node interface. 

28. Can you name any 4 general password rules for a User account?

The important password rules for User account are mentioned below:

  • Include a total of at least eight characters.
  • You should employ a string in a novel way.
  • You must not frequently use birthdays and anniversaries.
  • Don’t overuse words that can be found in a dictionary.

29. How can you append one file with another?

The operator “>>” can be used to append a named file with another file. To append 2 files together, the following command can be used:
cat file 3 >> cat file 4

In order to append more than 2 files, you can use the following command line:

cat file 4 > cat file 5 > cat file 6

Notice how the operator “>” is used to append more than two files.

30. What are the main types of Linux shells?

Before knowing the different types of Linux shells, it is important to know what a shell is! A shell is a software that acts as a user interface. It connects the user with the Linux kernel. You can write instructions and programs in the shell in order to talk to the Linux kernel.

There are 5 types of shells in Linux:

To safeguard your digital world, it is essential to comprehend the most important 20 cyber security secrets. In this blog post, we will explore every secret in depth so you understand how best to put safety measures into place.

Top Cyber Security Secrets to protect your privacy from a cyber attack

The top Cyber security secrets to protect our privacy are as follows-

  • Solid Passwords

A key element of cyberspace defense lies in having secure passwords; ones that are not easy for other people or automated bots to guess correctly – after all, why make things simple?

  • A Sturdy Password Should Be At Least 12 Characters Long

Constructing a strong password which is at least twelve characters long, comprising of a mix of upper and lowercase letters, numbers and symbols – might help protect your online accounts better. Avoid employing easily guessable information such as date of birth or pet names.

  • Two-Factor Identification (2FA)

Giving two-factor identification adds an extra layer of safety to your on-the-web accounts. With 2FA you have to present another type of validation in conjunction with your code word, for example, a fingerprint scan or a unique number given by an authentication app.

  • Regular Software Upgrades

Staying on top of your software is essential to keeping it secure from cyber attacks. Most updates include fixes that target security problems, so make sure you keep an eye out for the latest ones and get them installed as soon as possible in order to give yourself the best protective features available.

  • Lockdown Your Wi-Fi Network

Making sure your Wi-Fi network can’t be accessed without permission is a must if you want to stay safe online. Change default usernames and passwords on routers, switch up encryption settings with WPA2 protocols and craft strong passwords for all networks – it might seem like hard work but trust me when I say it’s worth taking these precautions!

  • Be Careful With Email Attachments

Beware email attachments – they could contain harmful malware or viruses which would risk infecting your device if opened up… Better safe than sorry!

  • Take Care when Opening Attachments

Be extra vigilant when it comes to opening attachments from unknown senders – scan them using a trustworthy anti-virus before you open them. Taking this precaution could be the difference between keeping your data secure and falling foul of cybercriminals.

  • Install Firewall Protection

A firewall works as a barrier, looking over any traffic coming in or out of your network to block potential hackers. Setting up one is an additional way that can help safeguard against malicious attacks on your system.

  • Regularly Back Up Your Files

Never forget about backing up all important files and documents! In case something unfortunate happens like ransomware infiltrating your computer or hardware failure, having regular backups stored away will make sure the disruption caused by such events is kept at bay. Automate the backup process for added convenience.

  • Utilize Antivirus Software

Antivirus software scans and identifies malicious programs on your gadgets. Invest in trusty antivirus software and keep it up to date to guard against the latest dangers. Do regular checks to make sure your system is sanitized.

  • Observe Secure Browsing Habits

Adopt safe browsing habits so you can cut down the chances of being exposed to cyber attacks even more. Resist clicking any suspicious links, only download stuff from reliable sources, and take extra care when imparting personal info online.

  • Make the Most of Virtual Private Networks (VPNs)

If you are connecting to a public Wi-Fi network or accessing sensitive info online, VPNs can help you keep your data secure. How? They encrypt your internet connection and deter hackers from intercepting it. A must if digital security is important to you!

  • Put Access Controls in Place

Putting access controls into practice means only authorized individuals have access to sensitive information and systems – this could be anything from using strong passwords to limiting user privileges and regularly reviewing/updating who has authorization.

  • Use Encryption for Sensitive Data

Encrypting our most valuable data makes sense; after all, turning it into unreadable code makes it difficult for anyone without permission getting their hands on what’s not theirs anyway – trust us, encryption will pay off here!

  • Watch Out for Phishing Ploys

Phishers are notorious for sending out fraudulent emails or creating clone websites that look just like legit organizations, in a bid to mislead users into giving away personal info. So be aware and check the legitimacy of any emails or webpages before you enter your details.

  • Give Your Mobile Handsets Extra Security

With mobiles being so widely used nowadays, they’re prime targets for cybercriminals – there’s no doubt about it! Make sure passwords/biometric authentication is enabled on them; install security apps from reputable sources; try not to download applications from untrustworthy sites either.

  • Practice Social Media Discretion

Take a look at your social media privacy settings and reduce the personal details you’re sharing online. When it comes to accepting friend requests from unknown people on social media, proceed with caution!

  • Educate Employees about Cyber Security Standards

If you have staff, make sure everyone knows the basics of cyber security – including how to recognize phishing attempts, secure passwords and be careful when dealing with business information.

  • Keep an Eye on Financial Accounts Regularly

Keep tabs on your financial accounts regularly so that if anything dodgy is happening then you spot it quickly enough. It’s always best to be one step ahead in such cases! Set up alerts for bank account activity and report any unrecognized transactions straight away to your financial institution.

  • Ensure Physical Gadgets are Secure

Physical security is often neglected but it’s just as essential in internet safety. Make sure that your devices remain safe by locking them when they’re not being used, and putting them away securely. This stops unauthorized access which could lead to a data breach.

  • Deploy Role-Based Access Control

RBAC provides permissions determined by someone’s role in an organization, only allowing individuals the authority they need for their role directly related to duties. Have you ever thought about how important physical device protection really is? How much this can help protect against unwanted breaches of data? 

Why should I learn about Cyber Security?

Cisco Virtual Switching: Explained

by
Cisco Virtual Switching: Explained
Cisco Virtual Switching: Explained

The Cisco Virtual switching system is the technology introduced in CISCO catalyst 6500 series switches, which overcomes the drawback of EtherChannel and Spanning Tree protocol. It allows two catalyst switches to work as a single virtual switch. 

Before understanding how it works and its benefits, let us first understand the Cisco Three-Layer Hierarchical Model. 

What is the Cisco Three-layer Hierarchical Model? ​

The Cisco Three-Layer Hierarchical Model divides a network into three different layers, namely: –  

  • The Access Layer   
  • The Distribution Layer   
  • The Core Layer 

But why do we need these layers?  

Initially, the topology of networks was called the flat topology, which looks like this: – 

Flat Switched Network

If we need to expand this network, more switches need to be added since the number of end devices increases. This topology restricted us to control the broadcast and undesirable traffic. With the increase in the number of devices, response time decreases, and hence the efficiency of the network reduces. 

NOTE: Flat topology might work for small networks, but in the case of medium-sized and large networks, this topology is inefficient. 

With the help of the Hierarchical Model, which divides the network into discrete layers, the network designer can optimize the network. Basically, with the help of this model, we divide a large network into smaller and manageable network segments. Also, the network is divided and managed in such a way that traffic that is required goes to the upper layer of the Hierarchy.   

NOTE: With the help of this, the broadcast domain also increases. 

Let us discuss each layer of this model: –   

  • Access Layer 

At the bottom of the hierarchy, the Access layer connects end-user devices, such as computers, printers, phones, and IoT devices, to the network. This layer ensures that devices can communicate with one another and access network resources. It provides connectivity between workstation servers.  

The access layer helps to perform layer-2 switching, port security, QoS classification, Address Resolution protocol inspection, etc. 

  •  Distribution Layer 

The middle layer is called the Distribution layer, which acts as a traffic aggregator and controls the data flow between the Access and Core layers. The distribution layer is responsible for managing VLANs, which helps to segment the traffic. The distribution layer helps aggregate the WAN and LAN links, provides policy-based security using ACL and redundancy, controls the broadcast domain, ensures optimal traffic distribution, and helps in routing and filtering services.  

  • Core Layer 

The Core layer is the topmost layer of the hierarchy and is responsible for high-speed, low-latency data forwarding. It connects distribution layer devices, providing a high-speed backbone that ensures rapid data transmission. The Core layer is designed for reliability, often utilizing redundancy and fault-tolerant configurations to maintain uninterrupted connectivity. It consists of high-speed Cisco catalyst devices. 

What are the benefits of the Cisco Three-layer Hierarchical Model? ​

The benefits of the Cisco Three-Layer Hierarchical Model are as follows- 

  • Scalability 

One of the most significant advantages of the Three-Layer Hierarchical Model is its scalability. By dividing the network into distinct layers, it becomes easier to expand and adapt as your organization grows. Adding more Access layer switches or upgrading the Core layer can be done with minimal disruption to the existing network.  

  • Management 

The modular structure of the model simplifies network management. Each layer has a specific role and set of responsibilities, making it easier to troubleshoot issues. This simplicity also helps in the efficient allocation of resources and reduces the complexity of configuration.  

  • Security 

The Distribution layer’s role in traffic filtering and VLAN management enhances network security. By segmenting the network into VLANs you can isolate sensitive data and restrict unauthorized access. Additionally, the Distribution layer can implement access control lists (ACLs) to control traffic flow and protect against security threats.  

  • Improved Performance 

The Core layer’s high-speed backbone ensures rapid data transmission between different parts of the network, leading to improved performance and reduced latency, crucial for applications that demand real-time data transfer. 

What is a Cisco Virtual Switching System?

We needed redundancy in the network; hence redundant links were added. Then came the problem of loops. To avoid that, the Spanning Tree protocol came into the picture. Spanning tree is a useful protocol, but it comes up with some cost. Response time decreases, and we cannot use both links at the same time for forwarding traffic since STP will block one link.   

Yes, we are getting redundancy, but one of the links is useless, and we cannot do the load balancing. Sounds like an inefficient use of resources. In a Three-Layer Hierarchical Model, switches are given redundant links, but if one of the links gets blocked then it results in the wastage of resources. 

Virtual Switching System

VSS allows two (not more than two) separate physical switches to form a single virtual switch. It is supported by higher-end Cisco Switch series such as 45–/6500/6800. 

Switches in the stack are connected via a link called Virtual Switch Link. A single link can also be used to connect two switches, but two or more links are recommended to provide redundancy. A maximum of eight links can be connected to form a single VSL. 

We can even connect two switches kilometres apart and make it a VSL using fibre optic cabling. 

VSS allows
Virtual Switch

In the case of VSS, there is a single control plane but dual active forwarding planes. VSS helps to increase the forwarding capacity along with eliminating STP loops. One of the switches attains the Active mode while the other is in standby mode. 

NOTE: A switch with greater priority becomes an active switch while one with less priority becomes a standby switch. 

What is a Router MAC Address?

The Router MAC address gets derived from the chassis MAC EEPROM. Since both switches now act as a single virtual switch, the MAC Address should also be single. MAC Address gets negotiated at system initialization. The MAC Address of the active switch becomes the MAC Address of the virtual switch. MAC Address remains the same even if the active switch is shut for some reason so that the host does not need to do the ARP process for a new address. 

The links which connect the two switches are called Virtual Switch links. VSL passes two types of traffic: –  

  • VSS control traffic 

This traffic is used to control and maintain the Virtual Switch links.  

  • Data Traffic 

When traffic is received on one member must be sent out of an interface on the other member. 

Before the Virtual Switching System is activated, the Virtual Switch link, which links the switches must be up and running. When a switch boots the configuration for VSL gets parsed first. VSL interfaces are then enabled. VSS uses a Virtual switch link protocol, which is used to establish and maintain the VSL and VSS. 

What are the component protocols of the Virtual Switching System?

The Virtual Switching System has two component protocols:- 

  • LMP 

Link management protocol runs on each link that is a part of VSL and performs the following function: –  

  1. Verify link integrity by establishing bidirectional traffic forwarding.  
  2. Exchanges switch IDs and keepalive timers, hello timers, and hold timers. 

  • RRP 

Role resolution protocol performs the following function: –  

  1. Determine if the hardware and software versions of the switches are compatible or not  
  2. Determine the active and standby switches. 

Depending upon the compatibility, the standby switch comes up in one of two modes: – 

  • Route processor redundancy mode:- In this mode, the standby switch cannot forward traffic but is available as a backup if the active fails

Introduction: The Importance of Cybersecurity Courses

In today’s digital age, cybersecurity has become increasingly important. With the rise of technology and the internet, individuals and organizations are more vulnerable than ever to cyber threats. Cybersecurity training is essential to equip individuals with the necessary skills and knowledge to protect themselves and their organizations against these threats.

Cybersecurity refers to the practice of protecting computers, servers, mobile devices, electronic systems, networks, and data from digital attacks. It involves implementing measures to prevent unauthorized access, use, disclosure, disruption, modification, or destruction of information. The importance of cybersecurity cannot be overstated, as cyber attacks can have severe consequences, including financial loss, reputational damage, and even legal implications.

Understanding the Basics: Cybersecurity Fundamentals for Beginners

For beginners in the field of cybersecurity, it is important to understand the basics. This includes familiarizing oneself with common cybersecurity terminologies and concepts. Some common terms include malware, phishing, ransomware, encryption, firewall, and vulnerability. Understanding these terms will help individuals grasp the fundamentals of cybersecurity.

Basic cybersecurity principles and practices are also crucial for beginners. These include principles such as least privilege (giving users only the necessary access rights), defense in depth (implementing multiple layers of security), and continuous monitoring (regularly checking for vulnerabilities and threats). Practices such as regularly updating software, using strong passwords, and being cautious of suspicious emails or websites are also essential for beginners to adopt.

Cyber Threats and Attack Vectors: What You Need to Know

To effectively protect against cyber threats, individuals need to be aware of the different types of threats and their impact. Common types of cyber threats include malware (such as viruses, worms, and Trojans), phishing attacks (where attackers trick individuals into revealing sensitive information), ransomware attacks (where attackers encrypt data and demand a ransom), and DDoS attacks (where attackers overwhelm a network with traffic).

Understanding the common attack vectors used by cybercriminals is also important. Attack vectors refer to the methods or paths that attackers use to gain unauthorized access to systems or networks. Common attack vectors include social engineering (manipulating individuals into revealing sensitive information), software vulnerabilities (exploiting weaknesses in software), and brute force attacks (attempting to guess passwords).

To identify and prevent cyber attacks, individuals should be vigilant and adopt best practices. This includes regularly updating software and systems, using strong and unique passwords, being cautious of suspicious emails or attachments, and implementing security measures such as firewalls and antivirus software.

Best Practices for Cybersecurity: Tips and Tricks for Staying Safe Online

There are several best practices that individuals can follow to enhance their cybersecurity and stay safe online. One of the most important practices is effective password management. This includes using strong and unique passwords for each online account, regularly changing passwords, and using password managers to securely store passwords.

Another important practice is to identify and avoid phishing scams. Phishing scams are attempts by attackers to trick individuals into revealing sensitive information such as usernames, passwords, or credit card details. To avoid falling victim to phishing scams, individuals should be cautious of suspicious emails or messages, avoid clicking on suspicious links, and verify the legitimacy of websites before entering any personal information.

Securing devices and networks is also crucial for maintaining cybersecurity. This includes regularly updating software and operating systems, using antivirus software and firewalls, encrypting sensitive data, and being cautious of public Wi-Fi networks. Additionally, individuals should be mindful of the information they share online and on social media platforms, as this can be used by attackers for targeted attacks.

Cybersecurity Tools and Technologies: An Overview

There are various cybersecurity tools and technologies available to help individuals protect against cyber threats. These tools can range from antivirus software and firewalls to intrusion detection systems and vulnerability scanners. It is important to choose the right tools for your needs and to use them effectively.

Antivirus software is one of the most basic and essential cybersecurity tools. It helps detect and remove malware from devices. Firewalls, on the other hand, act as a barrier between a trusted internal network and an untrusted external network, filtering incoming and outgoing network traffic. Intrusion detection systems monitor network traffic for suspicious activity and alert administrators of potential threats.

Vulnerability scanners are tools that scan systems or networks for vulnerabilities that could be exploited by attackers. These tools help identify weaknesses in software or configurations that could be used to gain unauthorized access. Encryption tools are also important for protecting sensitive data. They encrypt data so that it can only be accessed by authorized individuals with the decryption key.

Cybersecurity Certifications: Which Ones Should You Pursue?

Obtaining cybersecurity certifications can greatly enhance one’s career prospects in the field. There are several popular cybersecurity certifications that individuals can pursue, depending on their career goals and interests.
