User Access ControlSECURE CO NSO LE S ERVERS

2.4 User Access Control

Access to a Port is controlled on a per-user basis via a user profile, which is stored

as a file on the local SCS. This profile is created by the root user using the command

‘adduser’. See Section 8.1.1, adduser, on page 68.

2.4.1 User Sessions

Each SCS supports up to 250 simultaneous user sessions. This is possible since a

user can generate multiple sessions. This number of sessions is perceived to be far

greater than would be needed in most SCS product applications.

2.5 Port Buffers

The Secure Console Servers provide real-time serial port data buffering. Each Port

buffer stores up to 256 KB of data in a buffer, held in RAM in a separate file. This

provides hundreds of pages of port data for each attached device, which can be

reviewed at a later time. The data may be viewed while users are not interacting with

the attached port. Port buffers are enabled by default.
