There are three key points that we will talk about here. First of all, user accounts. Hijacking is a frequently used system breach. Be sure to check that a particular user’s account can’t be hijacked by another user. Secondly, performance and data integrity. Standard workflows and functionalities might not be under as much risk of being hacked, but they’re the parts most vulnerable to being bug-infected. So,, to maintain safety, you need to try corrupting each and every feature of the system. Thirdly, limitations. The administrator may limit access or functionality for different users. Therefore violation of access controls becomes an essential part of the testing.
