Protection and access
Decide what reaches the server, find malware, and control who can sign in to the host.
Protection holds the firewall rules that decide what reaches the server. Guard refuses addresses after repeated failed sign ins, and Web firewall filters requests to each site.
Malware scans accounts and quarantines what it finds. Advisor gathers findings from across the server and says what to do about each, and Security event review lists events for a person to look at.
SSH access decides who can sign in to the host and how, and Root access decides who can become root. Plan a change there before you apply it, so nobody is locked out.
Your own password, second factor and sessions are under Login and security in the account menu.
