SSH-2 with Critical System Protection

Hi Guys,

I have SCSP 5.2.9 in a vulnerability assesment we received the following recomendation:

"Stop Using SHA-1

Stop using signature algorithms relying on SHA-1, such as "SHA1withRSA", when signing X.509 certificates. Instead, use the SHA-2 family (SHA-224, SHA-256, SHA-384, and SHA-512). "

How can wecorrect thisvulnerability..?

It is installed onWindows2008 R2

Thanks.
