Description
An effective awareness program explains proper rules of behavior for use of an organization's IT systems and information. Accordingly, awareness programs should include guidance to users on malware incident prevention, which can help reduce the frequency and severity of malware incidents. Organizations should also make users aware of policies and procedures that apply to malware incident handling, such as how to identify if a host may be infected, how to report a suspected incident, and what users need to do to assist with incident handling. Ensuring the antivirus software alerts the users when a buffer overflow is detected will ensure the user is aware of the incident and be able to more closely relate the incident to actions being performed by the user at the time of the detection.
