12.2 Restoring Previous Security Settings for Identity Server

12.2.1 Restoring the Previous Protocols Settings

  1. Open the backup server.xml. For location of the backup file, see Backed Up Configuration Files.

  2. Search for the sslProtocol attribute and copy the attribute value.

  3. Change to the Tomcat configuration directory:

    Linux: /opt/novell/nam/idp/conf

  4. Open the 4.3 server.xml file.

    Search for the sslProtocol attribute. You will see the following value:

    sslProtocol="TLSv1.2" sslEnabledProtocols="SSLv2Hello,TLSv1.1,TLSv1.2"

  5. Replace this attribute value with the previous value that you copied.

12.2.2 Restoring the Previous Settings of Ciphers for SSL Communication

  1. Open the backup server.xml. For location of the backup file, see Backed Up Configuration Files.

  2. Search for the cipher attribute in NIDP_Name="connector" inside the <Connectors> element and copy the list of ciphers.

  3. Using command prompt, change to the Tomcat configuration directory:

    Linux: /opt/novell/nam/idp/conf

  4. Open the 4.3 server.xml file.

    Search for the cipher attribute in NIDP_Name="connector" inside the <Connector> element.

  5. Replace this list of ciphers with the list copied in step 2.

  6. (Conditional) If you have multiple Identity Servers in your cluster configuration, repeat these steps on each Identity Server.

12.2.3 Disabling Perfect Forward Secrecy

  1. Open the backed up server.xml. For location of the backup file, see Backed Up Configuration Files.

  2. Search for the cipher attribute in NIDP_Name="connector" inside the <Connectors> element and copy the list of ciphers

  3. Using command prompt, change to the Tomcat configuration directory /opt/novell/nam/idp/conf:

  4. Open the server.xml file. Search for the cipher attribute in NIDP_Name="connector" inside the <Connectors> element.

  5. Replace the list of ciphers with the value you copied in step 2.

12.2.4 Restoring the Previous Settings of the Size of EDH Keys

  1. Open the /opt/novell/nam/idp/conf/tomcat.conf file.

  2. Remove the following line:

    JAVA_OPTS="${JAVA_OPTS} -Djdk.tls.ephemeralDHKeySize=2048"

12.2.5 Removing HTTP Strict Transport Security

  1. Change to the Tomcat configuration directory:

    /opt/novell/nam/idp/conf/web.xml

  2. Open the web.xml file and comment out the httpHeaderSecurity filter definition.

    <filter>
    <filter-name>httpHeaderSecurity</filter-name>
    <filter-class>org.apache.catalina.filters.HttpHeaderSecurityFilter</filter-class>
    <async-supported>true</async-supported>
</filter>

  3. Comment out the hstsMaxAgeSeconds parameter:

    <init-param>
    <param-name>hstsMaxAgeSeconds</param-name>
    <param-value>31536000</param-value>
</init-param>

  4. Comment out the filter mapping.

    <filter-mapping>
    <filter-name>httpHeaderSecurity</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
</filter-mapping>

12.2.6 Removing the Clickjacking Filter

  1. In the /opt/novell/nids/lib/webapp/WEB-INF/web.xml file, comment out the following tomcat filter configuration: 

    <filter>
    <filter-name>TomcatSameOriginFilter</filter-name>
    <filter-class>org.apache.catalina.filters.HttpHeaderSecurityFilter</filter-class>
    <init-param>
        <param-name>antiClickJackingOption</param-name>
        <param-value>SAMEORIGIN</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>TomcatSameOriginFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

  2. Restart Identity Server by running /etc/init.d/novell-idp restart.
