Port 135 Block Implementation Recently, the US Department of Homeland Security issued an advisory to Internet Service Providers, including Cox Communications. It warns of a potential network disruption due to a security loophole in the Windows 2000, XP, NT, and 2003 operating systems. This loophole may allow hackers unauthorized access to computers on our Cox High Speed Internet network and the Internet at large, using computer viruses or worms. The government has called for the filtering of three ports (ports 135, 137 and 445) to prevent hackers from exploiting the security loopholes. A port is basically a point of connection for a specific type of program. For example, whenever a request is sent to display a web page like www.cox.net, it is sent to port 80. Cox currently filters (in both directions) two of the ports identified in the advisory -- ports 137 and 445. This prevents computers on the Internet from talking to your computer on these ports. In the last week, the Cox Abuse department has seen a significant increase in the number of computers on our customer network that have been infected with viruses and worms; we are therefore complying with the Department of Homeland Security Advisory. The spread of infection is due to a high number of users operating exploitable versions of Microsoft Windows, primarily XP and 2000 (i.e. unpatched machines). Cox recommends that customers visit the Microsoft Windows Update website frequently to insure they are updating and protecting themselves from newly discovered exploits. Cox anticipates the filter of port 135 will be implemented in all markets by August 10th, 2003.
