A potential security risk lurks within every business, from the extensive enterprise computer network to the small business with a handful of synced desktops and laptops. This security hole can be attributed to administrator credentials. Plugging the hole is challenging because administrator accounts and their access credentials are essential to the security of the network. Still, they are often ignored.
Malicious or careless insiders can easily use administrator privileges to gain unlimited access to the network. Cybercriminals, who know all about administrator credentials, can crack weak or standardized administrator passwords to break into your system.
The Irony of Securing Administrator Credentials
The irony of this security risk is that administrator accounts were first developed as a basic security precaution against both user error and malicious intrusion. Most users do not need to perform system maintenance tasks such as installing software patches or modifying internal permissions, and they are usually happy to be relieved of the worry of accidentally causing system damage. Privileged administrator accounts shield most users from these complications and limit administrator powers to specific, trusted users.
But according to Infosec Island, administrator accounts and their credentials have proliferated in modern networks. A PC’s local operating system has an administrator account and password, but many network functions and services also have their own administrator credentials. As a result, it can be “tedious to locate, let alone update, all the local administrator accounts. And that doesn’t include the accounts used by tasks, services and COM objects on machines throughout the network. Consequently, many of these updates are never done,” InfoSec Island noted.
Worst of all, these network service administrator credentials are often given default factory settings that are never changed. The IT team may not even know that they exist.
Minimizing the Risk
Because this security risk takes multiple forms, several strategies must work in concert to protect against it. To minimize risks from insiders, organizations should disable computer ports for flash drives or CD-ROM drives whenever their use is not actually required.
Administrator passwords should be changed regularly. This is good practice for all passwords, but because administrator credentials are rarely used, it is all too easy to forget about them. Commercial tools for privileged identity management can automate the process of finding and managing those little-used administrator accounts. Still, the crucial first step in getting a handle on this security challenge is being aware that it exists across multiple administrator accounts.
