To be effective, ENS Sentinel 4-8 security needs to be up to date and have multiple levels. Sentinel 4/8 provides SSH v3.91.

The Sentinel uses the latest and greatest security and currently comes with SSH v3.91 and incorporates any additions or changes in the SSH encryption standard and makes them available within weeks of being released. The Sentinel generates both RSA and DSA keys instantly and allows you to validate certificates by Verisign at the press of a button.

The Scout II does not provide IP Packet Filtering to lock down access of groups or individual to specific equipment. The ENS uses IP packet filtering to further restrict and control access.

The Sentinel allows RADIUS, local authentication and Central Database Authentication, IP Packet Filtering and more. However, OutPost recommends against relying on RADIUS authentication because its technology needs to work when the network does not work. If there is a network issue you will be locked out of the network by relying upon the RADIUS server, which largely defeats the purpose of providing OBM.

Sentinel does not provide Access Control Lists (ACL) or redundant audit trails. Access Control Lists specify who and what machine has access to which equipment and what they can do to each piece of equipment. For example, using an ACL you can authorize Tech1 in the NOC to only view the status of all equipment, Tech2 can power the Cisco devices but only Tech3 has connect privileges to reconfigure the router. Tom can view it all from his desk in real time and see who has and is taking what actions.
