What is the most effective defense against cross-site scripting attacks? a) Limiting account privileges b)User Authentication c) Input validation d)encryption - Answer- c) Input validation prevents cross-site scripting attacks by limiting user input to a predefined range. This prevents the attacker from including the HTML ˂SCRIPT˃ tag in the input. What phase of the Electronic Discovery Reference Model puts evidence in a format that may be shared with others? a) production b) proce...
