I am looking through the security events within Event Viewer and I am noticing several login failure attempts for a user with the name of email@example.com
. This log occurs two times a day 7:30AM and 1:30PM. I have enforced security by enabling settings in the domain controller group policy, as well as modified settings in shared network resources ACL. What are some other steps I can perform to verify that my network is secure enough to block out unwanted access?
