A company has had several virus infections over the past few months. The infections were caused by vulnerabilities in the application versions that are being used.
Which of the following should an administrator implement to prevent future outbreaks?
Host-based intrusion detection systems
Acceptable use policies
Incident response team
As vulnerabilities are discovered, the vendors of the operating systems or applications often respond by releasing a patch. A patch is designed to correct a known
bug or fix a known vulnerability, such as in this case to be vulnerable to virus infections, in a piece of software.
A patch differs from an update, which, in addition to fixing a known bug or vulnerability, adds one or more features to the software being updated.
