gets and sets. Since SNMP v2C uses community strings for authentication, only gets are

allowed under SNMP v2C.

SSLv3.1/TLS Requirements and Cryptographic Algorithms

When negotiating SSLv3.1/TLS cipher suites, only FIPS approved algorithms must be

specified.

All other versions of SSL except version 3.1 must not be used in FIPS mode of operation

The following algorithms are not FIPS approved and should not be used in the FIPS-

approved mode:

MD5

RC4

RC2

DES

Remote Access

1. Telnet access to the module is only allowed via a secure IPSec tunnel between the remote

system and the module. The Crypto officer must configure the module so that any remote

connections via telnet are secured through IPSec, using FIPS-approved algorithms. Note

that all users must still authenticate after remote access is granted.

2. SSH access to the module is only allowed if SSH is configured to use a FIPS-approved

algorithm. The Crypto officer must configure the module so that SSH uses only FIPS-

approved algorithms. Note that all users must still authenticate after remote access is

granted.
