DISA Rule

SV-215700r521266_rule

Vulnerability Number

V-215700

Group Title

SRG-APP-000412-NDM-000331

Rule Version

CISC-ND-001210

Severity

CAT I

CCI(s)

• CCI-003123 - The information system implements cryptographic mechanisms to protect the confidentiality of nonlocal maintenance and diagnostic communications.

Weight

Fix Recommendation

Configure the Cisco router to implement cryptographic mechanisms to protect the confidentiality of remote maintenance sessions using a FIPS 140-2 approved algorithm as shown in the examples below.

SSH Example

R1(config)#ip ssh server algorithm encryption aes128-cbc aes128-ctr aes192-cbc aes192-ctr

HTTPS Example

R2(config)#ip http secure-ciphersuite aes-128-cbc-sha

Check Contents

Review the Cisco router configuration to verify that it is compliant with this requirement.

SSH Example

ip ssh version 2
ip ssh server algorithm encryption aes128-cbc aes128-ctr aes192-cbc aes192-ctr

HTTPS Example

ip http secure-server
ip http secure-ciphersuite aes-128-cbc-sha
ip http secure-client-auth
ip http secure-trustpoint CA_XXX

If the router is not configured to implement cryptographic mechanisms to protect the confidentiality of remote maintenance sessions using a FIPS 140-2 approved algorithm, this is a finding.

Vulnerability Number
