Aim higher college has deployed an open source blog package. this package uses a database backend and allows users to create user ids, sites, and their own content to post it. recently, the service has had off-campus users who have posted links that appear to be directed towards university resources, but they are getting redirected toward off-campus malware sites. what would you recommend that the application administrator should do?

The application administrator should tighten measures on the external application used in the database backend especially when it comes to creating user IDs in order to prevent unauthorized users - any off-campus or even non-affiliated users to indiscriminately post links, especially malware and malicious ones. This can be done by selecting a viable verification method in order to only allow on-campus students to sign-up to the service.
