  • Place the Network DLP Management console only on a trusted network.
  • Give accounts on Network DLP systems only to personnel with a "need-to-know".
  • Apply network restrictions such that only Network DLP Appliances can communicate with Network DLP Managers.
  • Use only a single network interface card (NIC) for inter-system communications.
  • Present management functions only on a single NIC. Configure the management NIC to accept connections only from a trusted, restricted network.

What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council's effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, visit the CVSS website at: http://www.first.org/cvss/.
 
When calculating CVSS scores, McAfee has adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by the successful exploitation of the issue being scored.
