• conf_purge - [ Optional[Boolean] ] - Default: undef - Setting purge to true means that no default values will be used. WARNING: You MUST configure ALL CONFIG OPTIONS when using purge to ensure that AIDE can function.
• conf_db_dir - [ Optional[String] ] - Default: /var/lib/aide - The directory AIDE will use to store the DB.
• conf_log_dir - [ Optional[String] ] - Default: /var/log/aide - The directory AIDE will use to store the log file.

• conf_report_urls - [ Optional[Array[String]] ] - Default: ["file:@@{LOGDIR}/aide.log", "stdout"] - Where AIDE should send check results.
• conf_rules - [ Optional[Array[String]] ] - Default: ["PERMS = p+u+g+acl+xattrs", "CONTENT_EX = sha256+ftype+p+u+g+n+acl+xattrs"] - Custom rule definitions for the AIDE config file. Each item is passed into the config as is, so rule definitions should look like: "PERMS = p+u+g+acl+selinux+xattrs". See docs for defaults.
• conf_checks - [ Optional[Array[String]] ] - Default: ["/boot/ CONTENT_EX", "/bin/ CONTENT_EX", "/sbin/ CONTENT_EX", "/lib/ CONTENT_EX", "/lib64/ CONTENT_EX", "/opt/ CONTENT_EX", "/root/\\..* PERMS", "/root/ CONTENT_EX", "!/usr/src/", "!/usr/tmp/", "/usr/ CONTENT_EX", "!/etc/mtab$", "!/etc/.*null", "/etc/hosts$ CONTENT_EX", "/etc/passwd$ CONTENT_EX", "/etc/group$ CONTENT_EX", "/etc/gshadow$ CONTENT_EX", "/etc/shadow$ CONTENT_EX", "/etc/resolv.conf$ CONTENT_EX", "/etc/login.defs$ CONTENT_EX", "/etc/libuser.conf$ CONTENT_EX", "/var/log/faillog$ PERMS", "/var/log/lastlog$ PERMS", "/var/run/faillock/ PERMS", "/etc/pam.d/ CONTENT_EX", "/etc/security$ CONTENT_EX", "/etc/securetty$ CONTENT_EX", "/etc/polkit-1/ CONTENT_EX", "/etc/sudo.conf$ CONTENT_EX", "/etc/sudoers$ CONTENT_EX", "/etc/sudoers.d/ CONTENT_EX", "!/var/log/sa/", "!/var/log/aide.log", "/etc/ PERMS", "!/var/log/httpd/", "!/opt/puppetlabs/puppet/cache/", "!/opt/puppetlabs/puppet/public/last_run_summary.yaml"] - Directory and file checks. As AIDE parses these from top to bottom in the config file, the way you order this array matters. Individual file checks should come before their parent directory checks. Each check is passed into the config as is, so checks should look like: "/boot/ CONTENT_EX". See docs for defaults. If you choose not to use the default values, it is HIGHLY RECOMMENDED that you ignore the directory /opt/puppetlabs/puppet/cache/ and ignore the file /opt/puppetlabs/puppet/public/last_run_summary.yaml as these change every Puppet run.

1.4.1 - Ensure bootloader password is set

Parameters:

• password_protect - [ Boolean ] - Default: true - Whether or not to password protect the bootloader.
• superuser - [ Optional[String[1]] ] - Default: undef - The username of the grub2 superuser. This is used to set a superuser password in the bootloader configuration. This is only used if password_protect is true.
• superuser_password - [ Optional[Sensitive[String]] ] - Default: undef - The password of the grub2 superuser. This will be the superuser password in the bootloader configuration. This is only used if password_protect is true.
• password_file - [ Stdlib::UnixPath ] - Default: /etc/grub.d/50_password - The path to the file containing the bootloader password(s). This is only used if password_protect is true.
• replace_password_file - [ Boolean ] - If true, replaces the password file if it exists with a NEW hash of the password. Also, when set to true, this resource is NOT idempotent. When set to false, this prevent accidental overwriting of the password file with a new hash of the same password.
• hash_superuser_password - [ Boolean ] - Default: true - If true, the superuser password will be hashed using PBKDF2-HMAC-SHA512. If false, the superuser password will be stored in the password file as-is. This is only used if password_protect is true.
• superuser_password_salt_length - [ Optional[Integer] ] - Default: undef - The length of the salt in bits used to hash the superuser password. Default is 128. This is optional and only used if password_protect and hash_superuser_password are true.
• superuser_password_buffer_length - [ Optional[Integer] ] - Default: undef - The length of the resulting hash. Default is 128. This is optional and only used if password_protect and hash_superuser_password are true.
• superuser_password_iterations - [ Optional[Integer] ] - Default: undef - The number of times the password is passed through the hash function. Default is 120000. This is optional and only used if password_protect and hash_superuser_password are true.
• other_users - [ Optional[Array[Struct[{username=>String[1], password=>Sensitive[String], salt_length=>Optional[String], buffer_length=>Optional[Integer], iterations=>Optional[Integer]}]]] ] - Default: undef - An array of structured hashes to add other users besides the superuser to the password file. This is optional only used if password_protect is true. The users specified here will be added to the password file as regular users, not superusers. Other user passwords will be hashed using PBKDF2-HMAC-SHA512, just like the superuser password, if hash_other_user_passwords is true.
