What is Service account?
A login used by software rather than a person, which is why it is rarely watched and often over-privileged.
A service account is a login used by an application, script or system process rather than by a person. Backup software, databases and integration tools all run under service accounts.
They are attractive to attackers because they often hold broad permissions, have passwords that never change and are excluded from multi-factor authentication. Their logins also look routine, so misuse is easy to miss.
