Retina is a vulnerability management program offering a compliance element designed to help organizations of all sizes with vulnerability assessment and mitigation, as well as protection. The program uses recommended testing standards that organizations should follow to meet their security protocols.
Among those standards are some used for assessment. Vulnerability scanners should test clients (desktop PCs) and server computers (hardware), but they should also test the applications running on all systems, including web files, databases and network programs.
The vulnerability scanners should also provide mitigation. For example, zero-day attacks occur when hackers decide to expose the vulnerabilities of a recently released software program, causing it to crash. Hacker attacks could also open up the newly released program to virus infections. Mitigation software prevents outside entities from manipulating the new application, preventing zero-day attacks.
Finally, a vulnerability scanner also offers protection from well-known and established viruses. The scanner should have a database of known viruses and update that database frequently.
