5. Secured data sharing:
- Cyber security solutions also provide secure file sharing by providing encryption to all the transport layers, especially cloud security.
- It is done by enabling continuous compliance risk management.
6. Threat intelligence:
- By intelligently comparing aggregated log data with internal data from asset and configuration management systems, vulnerability scanners, etc. and external data from geolocation databases, etc., third-party cloud security vendors add context to streams of cloud-native logs.
- AI-based anomaly detection approaches are used to identify unknown risks. These dangers are then investigated using forensics to determine their risk profile.
- Real-time notifications on intrusions and breaches of policy reduce the time to recovery; in some circumstances, these alerts even initiate auto-remediation processes.
7. Defending critical systems:
- Wide-area network connections help avoid attacks on massive systems.
- It upholds rigid safety requirements that are industry-standard for users to follow in order to secure the devices using cybersecurity procedures.
- It continuously monitors all programs and assesses the security of the network, servers, and users.
8. Security for physical devices:
- Physical security measures include things like system locks, alarms, intruder detection systems, surveillance systems, and data-destruction systems.
- These make it possible for businesses to protect their IT infrastructure.
9. Disaster recovery and business continuity:
- Organizations can carry on functioning, thanks to data recovery in the event of data loss, attacks, or disasters.
- For example, in case there is some kind of data breach in an organization, the cyber security system already has all the backup of the data, sensitive information, files, folders, etc., on the cloud as well as locally (depending on the service you’re using).
- This application provides concepts or strategies that may assist businesses in managing significant data loss by frequently backing up data and spending money on a system that will allow business operations to continue.
- Thus, this use of cybersecurity ensures ongoing business operations.
10. Network monitoring:
- The practice of continuously scanning a network for signs of dangerous or intrusive behavior is known as network monitoring.
- It frequently works in collaboration with additional security technologies like firewalls, antivirus programs, and IDPs.
- The software allows for either manual or automatic network security monitoring.
- There are many open-source cyber security monitoring tools such as:
- OpenVAS (safari uses it), and many more!
11. Continuous investigation:
- Cybersecurity is useful while examining shady circumstances.
- It also aids in maintaining and following rules.
12. Software development security:
- By assisting in the early detection of software vulnerabilities during development, the program helps to ensure that rules and regulations are upheld.
- Software is thoroughly evaluated, scanned, and analyzed using cybersecurity technologies to find any defects, gaps, or vulnerabilities that could be exploited by hackers or rival companies.
What are the various types of cyber security threats?
It is important for cyber security professionals as well as business organizations to be aware of different types of cyber security threats. The most common types of threats are as follows:
- A form of malicious software known as ransomware encrypts a victim’s files or locks their systems and then demands payment in exchange for access.
- Attacks using ransomware can cost organizations a lot of money and interrupt their operations.
2. Phishing attacks:
- Phishing, which literally means “fishing,” describes a plan to recover sensitive information from users, such as passwords, financial information, or other private details.
- Phishing attempts frequently pretend to be from a reliable source, such as a bank website or email.
- Hackers frequently employ phishing emails or links to trick victims into disclosing their login information or other private data.
- Attacks using phishing are regularly utilized to make money.
- These attacks often come in the form of an email that appears to come from a legitimate source, such as a bank or credit card company.
3. Distributed Denial-of-Service (DDoS) attack:
- The attacker launches a Denial-of-Service (DoS) assault, such as a TCP SYN flood attack, by infecting numerous target users with malware. This is known as a distributed denial-of-service (DDoS) attack.
- A botnet is the collective name for the infected computers.
4. Man in the Middle (MITM) attack:
- Man in the Middle (MITM) attacks are among the most frequent kinds of security breaches.
- If you’ve ever wondered how hackers take over computers, steal personal data, or disrupt businesses, man-in-the-middle attacks are the recipe.
- If your email conversation is being forwarded to a third party, like Gmail or Microsoft Outlook, it would be an example of a man-in-the-middle attack.
5. Advanced Persistent Threats (APTs):
- PTs are highly organized cyberattacks that target specific organizations for surveillance, data theft, or disruption and are carried out by well-funded threat actors or nation-state groups.
- APTs often use cutting-edge methods and strategies to avoid detection and keep a constant presence inside a target’s network.
6. Internet of Things (IoT) security:
