6. Insider Threat

Insider threats involve malicious activities perpetrated by individuals within an organization, such as employees, contractors, or partners, who misuse their authorized access to compromise systems or steal sensitive data. 


  • Implement least-privilege access controls to limit users’ access to only the resources and data necessary for their job roles.
  • Conduct thorough background checks and screening processes for employees, contractors, and partners to mitigate the risk of insider threats.
  • Monitor user activity and behavior using security information and event management (SIEM) systems to detect and respond to suspicious or anomalous behavior.
  • Foster a culture of security awareness and accountability through ongoing training, communication, and security policies and procedures enforcement.

7. DNS Tunneling

DNS tunneling involves using DNS protocol to bypass traditional network security measures, exfiltrate data, or establish covert communication channels with malicious servers. 


  • Implement DNS security solutions such as DNS firewalls, DNSSEC (Domain Name System Security Extensions), and DNS sinkholing to detect and block malicious DNS traffic.
  • Monitor DNS traffic for anomalies and suspicious patterns that may indicate DNS tunneling activity.
  • Block unauthorized DNS requests and implement policies restricting outbound DNS traffic to trusted servers.
  • Educate users about the risks of DNS tunneling and the importance of maintaining vigilance when accessing external resources.

8. Eavesdropping Attacks

  • Eavesdropping attacks involve intercepting and monitoring communications to capture sensitive information, such as passwords, credit card numbers, or confidential business data. 


  • Use encryption protocols such as SSL/TLS (Secure Sockets Layer/Transport Layer Security) to secure data transmitted over networks.
  • Implement secure communication channels, such as VPNs (Virtual Private Networks) or encrypted messaging apps, to protect sensitive information from eavesdropping attacks.
  • Regularly update encryption keys and algorithms to mitigate the risk of cryptographic vulnerabilities and ensure the confidentiality and integrity of data in transit.
  • Educate users about the importance of using secure communication channels and avoiding unsecured public Wi-Fi networks to reduce the risk of eavesdropping attacks.

9. Watering Hole Attack

  • A watering hole attack involves compromising websites frequented by a target group of users and injecting malicious code to infect visitors’ devices with malware. 


  • Use web security solutions such as web application firewalls (WAFs) and content security policies (CSPs) to detect and block malicious code injection attempts.
  • Maintain up-to-date software and plugins for web servers and content management systems to patch known vulnerabilities that could be exploited in watering hole attacks.
  • Conduct regular website security audits to identify and remediate security weaknesses or suspicious activities.
  • Educate users about the risks of visiting untrusted websites and the importance of updating their browsers and plugins to prevent malware infections.

10. Man-in-the-Middle Attack (MITM)

A man-in-the-middle attack occurs when a malicious actor intercepts and relays communications between two parties without their knowledge, allowing them to eavesdrop on or manipulate the exchanged data. 


  • Use encryption protocols such as SSL/TLS or VPNs to establish secure communication channels and prevent unauthorized interception of data.
  • Implement certificate-based authentication to verify the identities of communicating parties and prevent MITM attacks.
