Security Overview
The GSR provides security features that help control access to the GSR and filter traffic
going through the GSR. Access to the GSR can be controlled by:
•
Enabling RADIUS
•
Enabling TACACS
•
Enabling TACACS Plus
•
Password authentication
Traffic filtering on the GSR enables:
•
Layer-2 security filters - Perform filtering on source or destination MAC addresses.
•
Layer-3 Access Control Lists - Perform filtering on source or destination IP address,
source or destination TCP/UDP port, TOS or protocol type for IP traffic. Perform
filtering on source or destination IPX address, or source or destination IPX socket.
Perform access control to services provided on the GSR, for example, Telnet server and
HTTP server.
Note:
Currently, Source Filtering is available on GSR WAN cards; however, application
must take place on the entire WAN card.
