The Cisco BGP router must be configured to use a unique key for each autonomous system (AS) that it peers with.

Description
If the same keys are used between eBGP neighbors, the chance of a hacker compromising any of the BGP sessions increases. It is possible that a malicious user exists in one autonomous system who would know the key used for the eBGP session. This user would then be able to hijack BGP sessions with other trusted neighbors.

Check Text (C-216992r945862_chk)

This check is Not Applicable for JRSS internal EBGP use. Review the BGP configuration to determine if it is peering with multiple autonomous systems. Interview the ISSM and router administrator to determine if unique keys are being used. router bgp xx no synchronization bgp log-neighbor-changes neighbor x.1.1.9 remote-as yy neighbor x.1.1.9 password yyyyyyyy neighbor x.2.1.7 remote-as zz neighbor x.2.1.7 password zzzzzzzzz If unique keys are not being used, this is a finding.

Fix Text (F-18220r287305_fix)

Configure the router to use unique keys for each AS that it peers with as shown in the example below. R1(config)#router bgp xx R1(config-router)#neighbor x.1.1.9 password yyyyyyyy R1(config-router)#neighbor x.2.1.7 password zzzzzzzzz
