Microsoft Windows Netlogon CVE-2016-3300 Remote Privilege Escalation Vulnerability

Description

Microsoft Windows is prone to a remote privilege-escalation vulnerability. An attacker can exploit this issue to gain elevated privileges within the context of the affected system.

Technologies Affected

Recommendations

Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isn’t needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.

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.
