AI-suggested

European organizations should ensure that all systems related to the retired directives are fully patched and configured according to current best practices. This includes: 1) Verifying that all Windows systems have applied patches from the relevant Patch Tuesdays (January 2020 and subsequent updates) addressing DNS server, Netlogon, and Print Spooler vulnerabilities. 2) Ensuring Microsoft Exchange servers are updated and hardened against known exploits. 3) Applying security updates and configuration changes for VMware and Pulse Connect Secure products. 4) Conducting threat hunting and forensic analysis to detect any residual or persistent access from past compromises, particularly for supply chain attacks like SolarWinds. 5) Implementing continuous monitoring and alerting for indicators of compromise related to these vulnerabilities. 6) Aligning internal vulnerability management processes with Binding Operational Directive (BOD) 22-01 principles, focusing on timely patching of known exploited vulnerabilities. 7) Enhancing collaboration with national cybersecurity agencies and sharing threat intelligence to stay ahead of emerging threats. 8) Adopting Secure by Design principles in procurement and system development to reduce future risk exposure. These steps go beyond generic patching by emphasizing proactive detection, operational resilience, and strategic alignment with evolving cybersecurity frameworks.
