Circumventing Security Controls in the NIST Cybersecurity Framework
Circumventing a security control means finding a way to bypass or avoid the control, often to gain unauthorized access to a system or data. In the context of the NIST Cybersecurity Framework, circumventing a security control can refer to any action or technique that allows an attacker to bypass or defeat the control, such as using a vulnerability or exploiting a weakness in the control.
Here are some examples of what might be circumvented in the NIST Cybersecurity Framework:
1. Access controls: An attacker might try to circumvent access controls by using stolen credentials or exploiting a vulnerability in the authentication process.
2. Firewalls: An attacker might try to circumvent firewalls by using a different port or protocol, or by exploiting a vulnerability in the firewall software.
3. Intrusion detection and prevention systems: An attacker might try to circumvent these systems by using evasive techniques, such as encrypting their traffic or hiding their activities.
4. Encryption: An attacker might try to circumvent encryption by using a weak key or exploiting a vulnerability in the encryption software.
5. Incident response plans: An attacker might try to circumvent incident response plans by delaying the discovery of the incident or by manipulating the response process.
6. Security policies and procedures: An attacker might try to circumvent security policies and procedures by exploiting gaps or weaknesses in the policies, or by using social engineering techniques to trick employees into violating the policies.
7. Network segmentation: An attacker might try to circumvent network segmentation by using lateral movement techniques, such as exploiting vulnerabilities in other systems or using phishing attacks to gain access to sensitive data.
8. Endpoint security: An attacker might try to circumvent endpoint security measures, such as antivirus software and firewalls, by using malware or other types of attacks that can evade detection.
Overall, the goal of circumventing security controls is to gain unauthorized access to a system or data, often for malicious purposes. The NIST Cybersecurity Framework provides a set of guidelines and best practices for organizations to follow in order to protect against these types of threats.
