Why is patch management so important? If your servers aren’t updated and managed properly, your data and applications are left vulnerable to hackers, identity thieves and other malicious attacks against your systems.
And when it comes to sensitive data and national industry compliance standards, such as HIPAA and PCI DSS compliance, your company can’t afford to suffer a data breach or theft, as the fines and estimated financial loss per data breach record continues to rise each year.
The above video was a concept exploit of the recent vulnerability MS11-83. The theory behind MS11-83 is that you can send specially crafted UDP packets to a target machine and gain access to it, whether the port is closed or not.

By comparison, the much talked about Stuxnet variant “Duqu” uses a Win32k TrueType font parsing engine vulnerability to inject itself into target machines. Unlike MS11-83, Duqu is a real-world example of the exploit that has the ability to cause considerable damage and spread itself by embedding itself into Microsoft Word documents sent as email attachments or even USB keys.
In each of these cases these vulnerabilities are known, and fixes have been released (though in Duqu’s case, there is only a temporary patch), and have been disseminated down to WSUS servers and individual computers worldwide. While MS11-083 has been patched within a week, Duqu was detected in the middle of October, with Microsoft releasing an advisory three weeks later. This exemplifies the importance of immediate patch management. One can little afford to not keep their public facing servers up-to-date with the latest patches.
Security is a paramount concern of clients, but so is the stability of your IT operations. Clients often mix and match patching levels to balance these two concerns. At Online Tech, we offer three different levels of patch management, notify clients of outstanding updates waiting to be applied, and offer any assistance with patch installation to ensure comprehensive security measures are implemented accurately and timely.
