Vulnerabilities

A Vulnerability is a state in a computing system (or set of systems) which either (a) allows an attacker to execute commands as another user, (b) allows an attacker to access data that is contrary to the specified access restrictions for that data, (c) allows an attacker to pose as another entity, or (d) allows an attacker to conduct a denial of service.Advisories relating to Symantec products may be viewed here.

Recommendations
  • Block external access at the network boundary, unless external parties require service.
    If global access isn't needed, filter access to the affected device at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of exploits.
  • Deploy network intrusion detection systems to monitor network traffic for malicious activity.
    Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
Updates are available. Please see the references or vendor advisory for more information.
