What is VirusScan Enterprise (VSE) 8.8 Cache persistence?

VirusScan Enterprise (VSE) 8.8 Cache persistence (also referred to as persistent cache) saves the existing cache to a file to prevent the loss of cache data. The saved cache contents can then be read after a restart. This dramatically improves VSE performance. For more information on the positive impact of VSE 8.8 cache persistence, see PD22973 - What’s New: McAfee VirusScan Enterprise, 8.8.

NOTE: VSE 8.8 cache persistence is enabled by default.



Considerations when using VSE 8.8  Cache persistence

• Laptops
  If using a laptop, you should use a bios boot password. This is good practice for laptop security in any event.
  
   
• Virtual Machine images
  When using cache persistence with Virtual Machine (VM) images, the VM server and storage infrastructure need to be secured to the same level or higher than the guest Operating Systems. Limit physical access and administrative access. Audit storage and data networks to ensure isolation between guest applications and VM server control and storage.
  
   
• Dual boot environments
  Do not use cache persistence in dual boot environments such as MacBooks with Bootcamp.
