The zero-hour interval is the time between the release of a new computer virus and the deployment of a corresponding anti-virus signature. Because modern viruses can copy themselves millions of times in the space of a few hours, individuals or organizations that employ only signature-based anti-virus defenses run a high risk of developing an infection during this time.
This report looks at ways to reduce this risk:
- Heuristic detection
- Use of overlapping AV products
- Blocking of email attachments
- Spam control
- Rigorous patching
- Use of virtual machines
It discusses each method and considers the best ones for administrators to apply. It also looks at the Avinti iSolation Server, a solution expressly designed to catch zero-hour viruses.
Report 580.
