2 Common Strategies for Cisco IOS Device Hardening

Today, organizations have to apply extreme diligence in not only ensuring their network security parameter is secure, but also ensure that network connected devices and mobile devices are secure to minimize the likelihood of sustaining a cyberattack conducted by exploiting a network-connected device. To do so, one of the best starting points is to leverage the AAA or Authentication, Authorization, and Accounting framework protocol to secure mobile devices.

The AAA security framework leads with effective authentication measures to ensure users accessing a network are, in fact, who they say they are. Authorization accounts for the strategy in granting or denying access to certain resources based on what access that use has been granted within the environment. This access control allows organizations to build unique policies defining who has access to what sensitive resources.

Lastly, Accounting of the AAA security model allows organizations to track a user's activity within the network and monitor what sensitive information that user has accessed.
