The NCSC warns that network defense strategies must adapt to newer threats, as attackers exploit vulnerabilities in network perimeter products like firewalls and VPNs. They suggest demanding security evidence from vendors, avoiding unverified products, reducing risk in self-hosted solutions, ensuring developer accountability, and adopting a cloud-first approach to security, emphasizing monitoring and quick response to threats.
The meeting notes discuss the evolving nature of cybersecurity threats and the need for a network defense strategy. It highlights the shift from perimeter security to targeting user devices and client software vulnerabilities by attackers. The UK’s National Cyber Security Centre (NCSC) recommends several actions for network defenders, including demanding security evidence from vendors, avoiding unverified products, and reducing risk in self-hosted solutions. The NCSC also suggests a cloud-first approach to security, emphasizing monitoring, updating software, implementing strong authentication measures, and conducting regular vulnerability assessments. Additionally, network defenders are encouraged to implement intrusion detection and prevention systems (IDPS) to monitor and block potentially harmful traffic in real time.
