Qualys devises a virtual patch to protect against vulnerabilities
If you can’t wait for that critical patch to secure your system from some just-discovered bug, IT security firm Qualys may have an answer, through new security software that can secure the trouble spot until the patch arrives.
The feature, called virtual patching, comes with the newly released version 2 of the company’s Web Application Firewall, a set of software for securing Web applications against malicious behavior.
Virtual patching can address one of the most thorny problems in enterprise IT security, that of protecting against a recently discovered software flaw. Sometimes attackers can start misusing a software bug as soon as it is discovered —- this is called a zero day flaw.
