Critical infrastructure security: the guidelines of CISA and NSA

The Cybersecurity and Infrastructure Security Agency (CISA) and the National Security Agency (NSA) recently released joint guidance on critical infrastructure security (ICS-OT). These guidelines were designed to provide a framework to help organizations managing critical infrastructure mitigate risk and protect their systems from cyber attacks. The main objective of these guidelines is to increase the security of critical infrastructures against threats such as targeted cyber-attacks, ransomware and supply chain compromises.

The impact on critical infrastructure

Guidelines from CISA and NSA emphasize the importance of close collaboration between critical infrastructure technology vendors and government agencies. While organizations managing critical infrastructures have traditionally taken reactive approaches to cybersecurity, the guidance emphasizes the need for a proactive approach. Recommendations include implementing risk management programs, segmenting networks, and constantly monitoring and assessing the security of third-party vendors.

Focus on emerging threats

A significant aspect of the CISA and NSA guidelines is the importance of addressing emerging threats. Organizations managing critical infrastructure must be prepared to face new types of cyberattacks that could exploit previously unknown vulnerabilities. The guide recommends staying up-to-date on the latest threats and vulnerabilities, adopting advanced detection strategies, and conducting incident exercises to test your response to attacks.

The future of critical infrastructure security

The publication of the CISA and NSA guidelines represents an important step towards greater security of critical infrastructures. However, the threat of cyberattacks will continue to evolve, requiring organizations to pay constant attention and update their security practices. To ensure effective protection of critical infrastructure, it will be critical that organizations rely on experienced cybersecurity professionals and adopt a mindset of continuous improvement and adaptation to emerging threats.
