Protecting virtualised environments
GCSx, the Government Connect Secure Extranet, is a powerful infrastructure for distributed communication. But a national, dispersed, typically mobile user base poses new security and performance challenges for public sector operations.
While the economies of virtual machines and virtual desktops make virtualisation a business imperative, conventional anti-malware solutions are not “virtually aware”, and a simultaneous full system scan can significantly degrade performance. To improve usability for remote users connecting via a VPN, security policies may be deliberately “relaxed”. If remote updating is disabled to preserve bandwidth, endpoints may become infected, jeopardising the entire network. The threat increases with out-of-hours use of home or unsecured networks.
