  10. Building Trust in Digital Interactions: Cybersecurity fosters trust in various online interactions, including communication, financial transactions, and the sharing of sensitive information, contributing to the overall stability and reliability of the digital landscape.

What are the key concepts in Cybersecurity?

The key concepts in Cybersecurity are as follows-

  • Threats and Attacks
  1. Malware: Malicious software like viruses and trojans, are designed to harm computers. It can compromise data, disrupt operations, or allow unauthorized access.
  2. Phishing: Deceptive tactics use fake emails or websites to trick individuals into revealing sensitive information, such as passwords or financial details.
  3. Ransomware: A type of malware that encrypts files, demanding payment for their release. It severely impacts individuals and organizations by denying access to critical data.
  • Vulnerabilities
  1. Software Vulnerabilities: Weaknesses in software code that attackers exploit. Regular updates and patches are crucial to enhance system security.
  2. Human Vulnerabilities: Actions or behaviours like weak passwords or falling for social engineering attacks that attackers exploit.
  3. Social Engineering: Manipulative techniques used by attackers to deceive individuals into revealing confidential information.
  • Defence Mechanisms

  1. Firewalls: Security barriers monitoring and controlling network traffic based on security rules. They protect trusted internal networks from untrusted external networks.
  2. Antivirus Software: Programs detecting and removing malicious software using signature-based detection and behaviour analysis.
  3. Encryption: It converts data into a coded form for confidentiality. Its kinds are as follows-
  • Symmetric Encryption: Uses a single key for encryption and decryption, fast but requires secure key distribution.
  • Asymmetric Encryption: Involves a pair of keys for enhanced security but with higher computational overhead.
  • TLS/SSL Protocols: Secure communication protocols using encryption for data protection during transmission over networks, commonly used for secure web browsing.

What are the types of cybersecurity threats and cyberattacks?

The types of cybersecurity threats and cyberattacks are as follows-

  1. Viruses: Programs that infect other software and spread when that software is run.
  2. Worms: Self-replicating malware that spreads without user intervention.
  3. Trojans: Malicious programs disguised as legitimate software to deceive users into installing them.
  • Phishing:
  1. Email Phishing: Deceptive emails aiming to trick users into sharing sensitive information.
  2. Spear Phishing: Targeted phishing attacks on specific individuals or organizations.
  3. Vishing: Phishing attacks are conducted through voice communication, often involving phone calls.
  • Ransomware:

It is malicious software that encrypts files, demanding payment for decryption keys. Examples include WannaCry and Ryuk.

  • Man-in-the-Middle (MITM) Attacks:

It intercept communication between two parties without their knowledge and allows attackers to eavesdrop or manipulate the communication.

  • Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks:
  1. DoS: Overloading a system or network to disrupt services.
  2. DDoS: Coordinated DoS attacks using multiple compromised systems.
  • SQL Injection:

It exploits vulnerabilities in web applications to execute malicious SQL commands and aims at gaining unauthorized access or manipulating databases.

  • Cross-Site Scripting (XSS):

It injects malicious scripts into websites viewed by other users and enables attackers to steal information or manipulate user interactions.

  • Zero-Day Exploits:

It targets undisclosed vulnerabilities in software before vendors release patches and exploits the time gap between discovery and resolution.

  • Insider Threats:

It refers to malicious activities or security breaches originating from within an organization.

  • Advanced Persistent Threats (APTs):

These refer to prolonged and targeted cyberattacks by well-funded and organized entities and aim to gain persistent access to a network for espionage or data theft.

  • IoT-Based Attacks:

These exploit vulnerabilities in Internet of Things (IoT) devices and can lead to unauthorized access, data breaches, or disruption of connected systems.

  • Social Engineering:

It manipulates individuals into divulging confidential information and includes techniques like pretexting, baiting, and quid pro quo.

  • Fileless Malware:

It exploits legitimate system tools and processes without relying on traditional files which is difficult to detect by conventional antivirus software.

  • Cryptojacking:

It refers to the illegitimate use of a victim’s computing resources to mine cryptocurrencies and can slow down systems and increase energy consumption.
