The Cybersecurity and Infrastructure Security Agency (CISA) has released a Cybersecurity Advisory detailing the findings of a red team assessment of a large critical infrastructure organization.
The red team was able to gain persistent access to the organization’s network and move laterally across multiple sites, accessing systems adjacent to sensitive business systems. The advisory highlights the importance of early detection and continual monitoring of cyber assets to reduce the threat of similar activity from malicious cyber actors.
The advisory provides network defenders with proactive steps to reduce the threat of similar activity, outlining the red team’s tactics, techniques, and procedures (TTPs) and key findings.
CISA encourages critical infrastructure organizations to apply the recommendations in the Mitigations section of the advisory to ensure security processes and procedures are up to date, effective, and enable timely detection and early mitigation of malicious activity.
The red team assessment was conducted on a large critical infrastructure organization with a mature cyber posture. Despite this, the red team was able to obtain persistent access to the organization’s network and move laterally across multiple geographically separated sites.
The advisory serves as a reminder that even organizations with a mature cyber posture are still vulnerable to attacks and that early detection and continual monitoring are essential to reduce the threat of cyber attacks.
In conclusion, the Cybersecurity Advisory released by CISA emphasizes the importance of early detection and continual monitoring of cyber assets to reduce the threat of cyber attacks. The advisory provides network defenders with proactive steps to reduce the threat of similar activity, outlining the red team’s tactics, techniques, and procedures (TTPs) and key findings.
CISA encourages critical infrastructure organizations to apply the recommendations in the Mitigations section of the advisory to ensure security processes and procedures are up to date, effective, and enable timely detection and early mitigation of malicious activity.
