Both reports found that insider attacks result in costly outages, lost business, legal liability and, inevitably, failed audits. In one case study, it took 115 employees 1800 hours to restore data deleted by a disgruntled insider. At the time of the attack, the perpetrator was an ex-employee of the IT department who was able to remotely access key systems. According to these reports, IT insiders commonly acquire and maintain powerful system access even after termination by using privileged accounts and passwords.
Privileged passwords have become a real concern for auditors and enterprises and here are six of the best practices that we’ve found are the best way to battle with this menace.
1. Create an Inventory of Privileged Passwords
Privileged passwords are the non-personal, shared passwords that exist in virtually every device or software application in an enterprise, such as root on a UNIX server, Administrator on a Windows workstation, and an Application ID used by a script to connect two databases. Many companies begin the process of securing their privileged passwords by taking an inventory of how many exist and how often they’re updated.
In this effort, it is important to note that privileged passwords exist in many places within your enterprise, such as:
- Administrative accounts that are shared by multiple IT professionals and come predefined by the manufacturer. These include UNIX root, Cisco enable, DBA accounts, Windows domain and so on.
- General shared administrative accounts, such as help-desk, fire-call, operations and emergency accounts.
- Hard-coded and embedded application accounts, including resource DB IDs, Generic IDs, batch jobs, testing scripts and application IDs.
- Service accounts such as Windows service accounts and scheduled tasks.
- Personal computer accounts, including the Windows Local Administrator on laptops and desktops.
