Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn’t needed, block access at the network perimeter to computers hosting the vulnerable operating system.

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 such as unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Do not accept or execute files from untrusted or unknown sources.
To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.

Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Do not use client software to access unknown or untrusted hosts from critical systems.
To limit the risk of exploits, never connect to unknown or untrusted services.
