.NET 1.1 Security risks

I am looking for justification to upgrade a server and .net framework(1.1) from a 2003 server to 2008r2 .NET 4.0 framework. I can think of a million reasons but what are security risks just in having the site be .NET 1.1 framework? Are there any technical articles I can reference?

Thanks

You might make it easy for yourself. .NET 1.1 is gone and does not even install on a modern machine. It does not go on Windows 7 Pro 64-bit, nor Windows 8 Pro 64-bit and then very unlikely on Server 2008 R2.

Server 2003 is going away in seven or eight months (no support), XP is going away at the same time. So all that is left is stuff that does not support .NET 1.1.

Hi thenrich,

Biggest security risk I can think of right away is, it is darn obsolete. So even if there are security vulnerabilities you will not get a fix for it.

The extended support ends on 10/8/2013
