The operating system of the hardware-based network engines, such as NAEs, SNEs, and SNCs, is secured using an account in the controller's embedded operating system. This account is the MetasysSysAgent account and is the only Windows account located on these devices. The account has administrative privileges and the password can be changed by logging in to the device directly with the Site Management Portal UI and resetting the password of the MetasysSysAgent user.
Many of the operating system features not required by Metasys software have been removed from the network engines, rendering them less vulnerable to operating system attack.
