Microsoft Security Update March 2012 ISO Image Download [KB913086]
Microsoft Security Update (The Patch Tuesday) is a security update released by Microsoft on the second Tuesday of every month. The security update for March 2012 is rather an important one because Microsoft has closed some important security holes in Remote Desktop Connection (RDC) which is installed in every Windows OS by default.
The security flaw was because of the exploitation by Morto worm which appeared last year. This particular worm opens a huge number of outbound connections by using svchost. This is due to the Morto worm which can also give the exploiter access to the file system of the affected system. If you are a network administrator, you should update your network of Windows immediately. If you are a home user and you are not using RDC, make sure that you have disabled it in Windows. Microsoft recommends that everyone updates their Windows systems with this security update.
If you are unable to update your network or system immediately, there is a workaround fix for this threat. You can enable Network Level Authentication (NLA) for your network. This will ensure some level of security for RDC security hole. You can use Microsoft Fix it utility for enabling or disabling NLA.
Other than that the security update does not include any major security updates. The following security bulletins are included in this March 2012 update:
