Solution: NOTE: This rule is created to block Google,this rule can be used to block any website that is needed by making changes accordingly.

In the SEPM console, in the system navigation bar, click Policies
In the View Policies navigation bar, select Intrusion Prevention
In the Tasks list, click Add a Custom Intrusion Prevention Signatures.
In the Custom Intrusion Prevention Signatures window, set the Name of the policy to Block Google (just an example, you can choose the website that you need to block).

Under the Signature tab, in the Signature Groups section, click Add
In the Intrusion Prevention Signature Group dialog, add the Group Name and Description as shown below, and then click OK.
Group Name: Block Google 
Highlight the newly created Signature Group (Block Google), then in Signature for this Group section, click Add
In the Add Signature window, fill in the following information shown below:

In the Content section add the following text:

rule tcp, dest=(80), msg="GOOGLE BLOCKED", content=""

Under the Action section do the following:

Click OK to close the Add Signature window. 
Click OK to close the Custom Intrusion Prevention Signatures window. 
When prompted to assign the policy, click Yes
In the Assign Intrusion Prevention Policy window, click the Global group, and then click Assign.
