Readers are reminded that the certification of this product (TOE) is the result of maintenance, rather than an actual re-evaluation of the product.  Maintenance only considers the affect of TOE changes on the assurance baseline (i.e. the original evaluated TOE); maintenance is not intended to provide assurance in regard to the resistance of the TOE to new vulnerabilities or attack methods discovered since the date of the initial certificate.  Such assurance can only be gained through re-evaluation. 

Using a security impact analysis of the changes made to the TOE, which was provided by the developer, the CCEVS has determined that the impact of changes on the TOE are considered minor and that independent evaluator analysis was not necessary.  A summary of the results can be found in the Maintenance Report, which is written in relation to the product's original validation report and Security Target.  Readers are therefore reminded to read the Security Target, Validation Report, and the Assurance Maintenance Report to fully understand the meaning of what a maintained certificate represents. 

Product Description

The changes are divided into two categories:  new features and bugfixes.

               New Features

The following new features in the product were analyzed and determined to be minor with minor security relevance. The following list describes only features that are relevant to the TOE and the claims that are made in the ST.

·         FlexVPN Event Trace—Displays event trace messages for FlexVPN.

·         MACsec exception reports for invalid keys and replay attacks-You can use the show mka policy command to verify the XPN configuration. If you do not want to include icv-indicator in MKPDUs, use the no include-icv-indicator command in the MKA policy.

·         MACsec varialble length CKN and optional support for ICV-Use the platform macsec logging replay protection command in global configuration mode to configure the packet count global configuration mode to configure the packet count.

·         PKI - EST CA Certs on Reykey-This feature enables client devices to obtain CA certificate automatically as part of rekey.

·         Removal of Weak Encryption Types 0, 5, and 7 in AAA—Support has been added for auto-conversion of weak password types 0 and 7 to encrypted password type 6.

·         Improvement in Crypto Performance with Crypto Offload.

·         Scale Improvement for IPSec VPN tunnels - With Cisco IOS XE Gibralter 16.10.1, the total number of IPSec VPN tunnels supported on C1100 series has increased to 1000, with HSECK9 license.

The features above are disabled by default and not included in the evaluated configuration or does not impact the TOE security functions.

             Bug Fixes — Vulnerability Analysis

The developer searched for publicly disclosed cybersecurity vulnerabilities applicable to versions of the TOE on 29 August 2019. The search resulted in 15 CVEs that were relevant to the TOE. All 15 CVEs have been mitigated by the Vendor.

Regression Testing:

Each individual change was unit tested, and the IOS-XE 16.12.1 software image has had a limited amount of automated regression testing covering all major areas of baseline client functionality. Testing was completed by Cisco Business Unit engineers and developers.


NIST CAVP Certificates

The developer confirmed the changed TOE conforms to NIAP Policy 5.  The operational environment under which the validated cryptographic algorithm implementation was tested is the same as the operational environment as the changed TOE.  Therefore, the cryptographic algorithm implementation validated for CAVP conformance also applies to the changed TOE.
