Revoked certificates are certificates that are compromised for some reason. A revoked certificate that is in use is a security risk. You have options when verifying certificate revocation. You can use a static list or you can verify revocations dynamically over the HTTP protocol. You have four ways to handle revoked certificates.
You can instruct IKEv1 to ignore CRLs or OCSP whose uniform resource indicator (URI) is embedded in the certificate. This option is shown in Step 5.
You can provide the CRL as an argument to the ikecert certrldb command. For an example, see Example 10–3.
Before You Begin
You must become an administrator who is assigned the Network IPsec Management rights profile. For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .
For information about the arguments to the ikecert certdb command, see the ikecert (1M) man page.
# ikecert certdb -lv cert-protect.example.com Certificate Slot Name: 0 Type: dsa-sha256 (Private key in certlocal slot ) Subject Name: <O=Example, CN=cert-protect.example.com> Issuer Name: <CN=ExampleCo CO (Cl B), O=Example> SerialNumber: 14000D93 Validity: Not Valid Before: 2013 Sep 19th, 21:11:11 GMT Not Valid After: 2017 Sep 18th, 21:11:11 GMT Public Key Info: Public Modulus (n) (2048 bits): C575A…A5 Public Exponent (e) ( 24 bits): 010001 Extensions: Subject Alternative Names: DNS = cert-protect.example.com Key Usage: DigitalSignature KeyEncipherment [CRITICAL] CRL Distribution Points: Full Name: URI = #Ihttp://www.example.com/pki/pkismica.crl#i DN = <CN=ExampleCo CO (Cl B), O=Example> CRL Issuer: Authority Key ID: Key ID: 4F … 6B SubjectKeyID: A5 … FD Certificate Policies Authority Information Access
Notice the CRL Distribution Points entry.
The URI entry indicates that this organization's CRL is available on the web.
The DN entry indicates that the CRL is available on an LDAP server. Once accessed by IKE, the CRL is cached for further use.
To access the CRL, you need to reach a distribution point.
# Use CRL or OCSP from organization's URI use_http …
Add the keyword proxy to the ike/config file. The proxy keyword takes a URL as an argument, as in the following:
# Use web proxy to reach CRLs or OCSP proxy "http://proxy1:8080"
Name the LDAP server as an argument to the ldap-list keyword in the host's /etc/inet/ike/config file. Your organization provides the name of the LDAP server. The entry in the ike/config file would appear similar to the following:
# Use CRL from organization's LDAP ldap-list "ldap1.example.com:389,ldap2.example.com" …
IKE retrieves the CRL and caches the CRL until the certificate expires.
If the CA's CRL is not available from a central distribution point, you can add the CRL manually to the local certrldb database. Follow the CA's instructions for extracting the CRL into a file, then add the CRL to the database with the ikecert certrldb -a command.
# ikecert certrldb -a < ExampleCo.Cert.CRL
