Access Banner
Since version 10.4 PKI Server can be configured with access banner (e.g. warning, terms of service) that will appear in PKI CLI, PKI Console, and PKI UI.
By default access banner is not installed, so no banner will be displayed when a client tries to access the server.
To install banner, create /var/lib/pki/pki-tomcat/conf/banner.txt containing a banner message, for example:
WARNING! Access to this service is restricted to those individuals with specific permissions. Any attempts to gain access, authorized or not, and all operations that follow, are audited and could be used against you in the court of law.
Make sure the file is UTF-8 encoded and readable by pkiuser. If the file contains invalid character(s) or not readable, the server will fail on restart and an error message will be logged in systemd journal.
To uninstall banner, simply remove the banner.txt.
No server restart is necessary when configuring banner message.
See also PKI Server Banner CLI.
Banner is displayed once at the beginning of each client’s SSL session. If there the client is idle, the session will expire after sometime (i.e. timeout). If the client creates a new session to continue the interaction with the server, the banner will be displayed again.
See Session Timeout.
Note that In earlier PKI the session timeout was defined in the following files:
-
PKI main webapp config (i.e.
/pki):/usr/share/pki/server/webapps/pki/WEB-INF/web.xml -
PKI subsystem webapp config (e.g.
/ca,/kra):/usr/share/pki/<subsystem>/webapps/<subsystem>/WEB-INF/web.xml
Since these files are shared, to change the session timeout first customize the webapps, then change the session timeout in the customized web.xml files, then restart the server.
In newer PKI 10.5 and PKI 10.6.9+ the session timeout is only defined in the Tomcat default webapp config:
-
Tomcat default webapp config:
/var/lib/pki/pki-tomcat/conf/web.xml
To change the session timeout simply edit the above file and restart the server.
In PKI UI the banner will appear in a dialog box when the user starts a session over an SSL connection. The banner may reappear if the user continues to use the UI after the session has expired (i.e. starting a new session).
In PKI Console the banner will appear before the console is displayed, for example:
$ pkiconsole https://pki.example.com:8443/ca WARNING! Access to this service is restricted to those individuals with specific permissions. Any attempts to gain access, authorized or not, and all operations that follow, are audited and could be used against you in the court of law. Do you want to proceed (y/N)? y
In PKI CLI the banner will appear before the actual operation is executed, for example:
$ pki ca-cert-show 0x1 WARNING! Access to this service is restricted to those individuals with specific permissions. Any attempts to gain access, authorized or not, and all operations that follow, are audited and could be used against you in the court of law. Do you want to proceed (y/N)? y ----------------- Certificate "0x1" ----------------- Serial Number: 0x1 Issuer: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE Subject: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE Status: VALID Not Before: Mon Feb 20 18:21:03 CET 2017 Not After: Fri Feb 20 18:21:03 CET 2037
To bypass banner (e.g. for automation) specify the --ignore-banner option, for example:
$ pki --ignore-banner ca-cert-show 0x1 ----------------- Certificate "0x1" ----------------- Serial Number: 0x1 Issuer: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE Subject: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE Status: VALID Not Before: Mon Feb 20 18:21:03 CET 2017 Not After: Fri Feb 20 18:21:03 CET 2037
