Enabling and Disabling Strict Authentication

After you have installed certificates on each EncrypTight component, you can enable strict authentication.
Strict authentication is a setting that affects communications between all EncrypTight components. Once
you enable strict authentication on a component, it begins to use certificates to authenticate
communications from devices that attempt to communicate with it. To use strict authentication system-
wide, you must specifically enable it in the EncrypTight software, the ETKMSs, and each PEP in use.
To enable strict authentication in the EncrypTight software:
1 In EncrypTight, select Edit > Preferences.
2Click ETEMS to expand the tree, and then click Communications.
3Click Use Strict Certificate Authentication for XML/RPC.
4Click OK.
To enable strict authentication on the ETKMSs, you need to edit the ETKMS properties file. The ETKMS
properties file kdist.properties is located in the /opt/etkms/conf directory.
To enable strict authentication on the ETKMS:
1 Log in directly on the ETKMS as root, or open an SSH session and su to root.
2Edit the kdist.properties file and set the strictCertificateAuth property to true. For
example:
strictCertificateAuth=true
3 Save and close the file.
4 At the command line type
service etkms restart
To enable strict authentication on PEPs:
1 For each PEP, in the Appliance Manager, right-click on the PEP and select Configuration.
2 In the Configuration editor, click the Features tab.
3Click Enable Strict Client Authentication.
4Click OK to close the warning message.
5Click OK to save and close the editor.
6 Select all of the PEPs that you changed.
7Click Put Configuration.
Ignore Failure to Respond Not receiving a response does not indicate that a certificate has
expired or that it has been revoked. This option allows the ETEP to
proceed when a response to an OCSP query is not received in a
timely manner. The default is to ignore the failure to respond.
Check Certificate Chain When checked, this option instructs the ETEP to use OCSP to
check the validity of every certificate in the responder’s chain of
trust. The default is unchecked.
OCSP URL Specifies the URL to use for the OCSP responder.
