AIX7-00-001105 - AIX must only allow the use of DoD PKI-established certificate authorities for verification of the establishment of protected sessions - Certificate Issuer
Untrusted Certificate Authorities (CA) can issue certificates, but they may be issued by organizations or individuals that seek to compromise DoD systems or by organizations with insufficient security controls. If the CA used for verifying the certificate is not a DoD-approved CA, trust of this CA has not been established. The DoD will only accept PKI-certificates obtained from a DoD-approved internal or external certificate authority. Reliance on CAs for the establishment of secure sessions includes, for example, the use of SSL/TLS certificates.
Note: Depending on which version of GSKit is installed on AIX, the GSK commands that are used to manage the Key Database (KDB) have different names. The possible GSK commands are: gsk8capicmd (used below), gsk8capicmd_64 and gsk7cmd. Create a key database with DoD PKI or DoD-approved certificate using one of the following commands: # gsk8capicmd -keydb -create -db <KDB_FILE> -pw <KDB_PASSWORD> -type cms -stash Edit '/etc/security/ldap/ldap.cfg' and add or edit the 'ldapsslkeyf' setting to reference a KDB file containing a client certificate issued by DoD PKI or a DoD-approved external PKI. Install a certificate signed by a DoD PKI or a DoD-approved external PKI using the following command: # gsk8capicmd -cert -add -db <KDB_FILE> -pw <KDB_PASSWORD> -file <CERT_FILE> -label <CERT_LABEL> Remove un-needed CA certificates using one of the following commands: # gsk8capicmd -cert -delete -db <KDB_FILE> -pw <KDB_PASSWORD> -label <CERT_LABEL> Restart LDAP client using command: # /usr/sbin/restart-secldapclntd
