+title: 'Harden OpenSSL Crypto Policy'
+
+description: |-
+ Crypto Policies are means of enforcing certain cryptographic settings for selected applications including OpenSSL.
+ OPenSSL is by default configured to modify its configuration based on currently configured Crypto-Policy. However, in certain cases it might be needed to override the Crypto Policy specific to OpenSSL r and leave rest of the Crypto Policy intact.
+ This can be done by dropping a file named <tt>opensslcnf-xxx.config</tt>, replacing <tt>xxx</tt> with arbitrary identifier, into <tt>/etc/crypto-policies/local.d</tt>. This has to be followed by running <tt>update-crypto-policies</tt> so that changes are applied.
+ Changes are propagated into <tt>/etc/crypto-policies/back-ends/opensslcnf.config</tt>. This rule checks if this file contains predefined <tt>Ciphersuites</tt> variable configured with predefined value.
+
+rationale: |-
+ The Common Criteria requirements specify that certain parameters for OpenSSL are configured e.g. cipher suites. Currently particular requirements specified by CC are stricter compared to any existing Crypto Policy.
