* Languages: Ansible, Bash, OVAL, Puppet
+shell_lineinfile::
+* Checks shell variable assignments in files.
+Remediations will paste assignments with single shell quotes unless there is the dollar sign in the value string, in which case double quotes are administered.
+The OVAL checks for a match with either of no quotes, single quoted string, or double quoted string.
+* Parameters:
+** *path* - What file to check.
+** *parameter* - name of the shell variable, eg. `SHELL`.
+** *value* - value of the SSH configuration option specified by *parameter*, eg. `"/bin/bash"`. Don't pass extra shell quoting - that will be handled on the lower level.
+** *no_quotes* - If set to `"true"`, the assigned value has to be without quotes during the check and remediation doesn't quote assignments either.
+** *missing_parameter_pass* - If set to `"true"` the OVAL check will pass if the parameter is not present in the target file.
+* Languages: Ansible, Bash, OVAL
+* Example:
+A template invocation specifying that parameter `HISTSIZE` should be set to value `500` in `/etc/profile` will produce a check that passes if any of the following lines are present in `/etc/profile`:
+** `HISTSIZE=500`
+** `HISTSIZE="500"`
+** `HISTSIZE='500'`
++
+The remediation would insert one of the quoted forms if the line was not present.
++
+If the `no_quotes` would be set in the template, only the first form would be checked for, and the unquoted assignment would be inserted to the file by the remediation if not present.
+

+title: 'SSH server uses strong entropy to seed'
+
+description: |-
+ To set up SSH server to use entropy from a high-quality source, edit the <tt>/etc/sysconfig/sshd</tt> file.
+ The <tt>SSH_USE_STRONG_RNG</tt> configuration value determines how many bytes of entropy to use, so
+ make sure that the file contains line
+ <pre>SSH_USE_STRONG_RNG=32</pre>
+
+rationale: |-
+ SSH implementation in RHEL8 uses the openssl library, which doesn't use high-entropy sources by default.
+ Randomness is needed to generate data-encryption keys, and as plaintext padding and initialization vectors
+ in encryption algorithms, and high-quality entropy elliminates the possibility that the output of
+ the random number generator used by SSH would be known to potential attackers.

+ To determine whether the SSH service is configured to use strong entropy seed,
+ run <pre>$ sudo grep SSH_USE_STRONG_RNG /etc/sysconfig/sshd</pre>
+ If a line indicating that SSH_USE_STRONG_RNG is set to 32 is returned,

Subject: [PATCH] Ansible mount_option: split mount and option task
Separate task that adds mount options mounts the mountpoint into two tasks.
Conditioning the "mount" task on the absence of the target mount option
caused the task to always be skipped when mount option was alredy present,
and could result in the mount point not being mounted.

Subject: [PATCH 2/3] no_shelllogin_for_systemaccounts: simplify check for
range of UIDs
There is no need to make calculations on top of the UIDs, we can compare
the collected UIDs with shell againt the states that define the valid range.
Avoiding the calculations has the added benefit of not using/referencing
a variable that can be empty (when no user has shell, except root).

+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.

- 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.
