Network Devices Need Least Privilege Too

Posted December 21, 2010    Peter McCalister

Any security infrastructure at an organization is only effective as its weakest link.  All too often, the weakest link in today’s enterprise networks are the non-production servers and network devices not deemed mission critical.  Eliminating shared passwords and logging activities down to the keystroke level on SSH-based network devices is a critical success factor for eliminating that security “weakest link”.

Implementing least privilege with a privilege identity management solution is the only way to ensure network devices aren’t susceptible to intentional, accidental or indirect misuse of privilege.  It closes an often overlooked “back door” frequented by hackers and malware who hijack accounts with admin or excessive privilege.

As seen in this diagram there are three levels of risk mitigation available.

  1. Vaulting passwords will let you know who was using the resource and when, but not what they did.
  2. Session management gives the who and when as well as what they did by logging everything and therefore, from a forensic perspective, you will know how to “unwind” what was done.
  3. Privilege delegation does all of the above, but also eliminates the possibility of someone doing something they should not be doing, thus stopping the problem before it occurs.

Implementing a privilege identity management solution across SSH based network devices can deliver the following key benefits:

  • Transparent role-based access to non-mission critical servers and devices
  • Full keystroke logging with firecall capability and auditing
  • Agentless deployment, no performance impact
  • Instantly indexable and searchable logging

“I’d love to come, but I’m on-call”: Privilege management can relieve holiday help desk headaches

Posted December 3, 2014    Jason Silva

Part of working in IT means you put in your time “on-call.” Companies either don’t realize there is a better way to allow users to maintain administrative access to endpoints, or they remove admin rights from users but don’t account for the resulting operational inefficiencies.
