This module installs and configures MISP (Malware Information Sharing Platform) on CentOS 7. It has been tested on Puppet 3.8.7 and with MISP versions 2.4.50 and 2.4.51.

Module Description

This module installs and configures MISP on CentOS 7. It installs all the needed dependencies, configures MISP and starts the services. However it does not set up the database nor the GPG key, that is up to the administrator to do. In addition it does not set up the web server on top of which MISP would run, meaning that Apache, Nginx or another web server of your choice would be needed (nevertheless the module need to know to know the name of the service of the web server (e.g. httpd)).

As mentioned before the database would need to be set up, the schema imported and then a user with rights to access the 'misp' database created. If GPG would be used, the GPG key would need to be created and placed in the configured directory (by default '/var/www/MISP/').

The module follows the installation instructions that can be found here. Also details about the database and GPG key creation and set up can be found there.

NOTE: the configuration and database files of MISP are used as templates on the module, therefore if the are major changes on the version of MISP the template might cause troubles and need to be updated.

Setup

What MISP affects

The MISP module will not alter any OS files, all the configuration will happen in '/config_dir/' (by default /install_dir/app/Config/') where the core.php, bootstrap.php, database.php and config.php files will be deployed with the established values.

This module needs the following packages:

* gcc: Needed for compiling Python modules
* git: Needed for pulling the MISP code and other git repositories which MISP depends on
* zip, redis, haveged and maria db
* python-devel, python2-pip, python-lxml, python-dateutil, python-six,: Python related packages
* rh-php56, rh-php56-php-fpm, rh-php56-php-devel, rh-php56-php-mysqlnd, rh-php56-php-mbstring, php-pecl-redis, php-pear: PHP 5.6 related packages
* php-mbstring, php-pear-crypt-gpg: Python package required by Crypt_GPG
* sclo-php56-php-pecl-redis: Redis related packages
* libxslt-devel', 'zlib-devel
* haveged

The services needed by MISP are:

* rh-php56-php-fpm
* haveged
* redis: This package installs the redis server, therefore it would only be installed if the 'redis' parameter is 
set to true. 
* The 4 workers and the scheduler [CakeResque]

Usage

Basic usage

In order to use the module it would be enough to include the module:

include ::misp,

Or the class:

class{ ::misp:}

And the module will use all parameters with default values, these values are specified later on.

Another usage example

class {'::misp':
    git_tag          => 'v2.4.67',
    email            => 'someone.someother@somewhere.ch',
    contact          => 'someone.someother@somewhere.ch',
    salt             => 'Rooraenietu8Eeyo<Qu2eeNfterd-dd+',
    cipherseed       => '9999999999999999999999999999999999999999999999999999999999999999',
  }

Parameters of the MIPS Class

The MISP class can take many parameters to change the configuration of MISP. However, they all have the default value set to the recommended value so there is no need to change it. The parameters can be classified in the ones needed for the installation of MISP itself, for the database, for the configuration and for the services. The parameters are the following:

MISP installation

  • misp_git_tag - Version of MISP that will be installed. By default "v2.4.71".
  • install_dir - Directory in which MISP will be installed. By default "/var/www/MISP/".
  • config_dir - Directory in which the configuration of MISP should be located. By default "/var/www/MISP/app/Config/".
  • stix_git_repo- Git url of the STIX module. By default "https://github.com/STIXProject/python-stix.git".
  • stix_git_tag- Version of the STIX module. By default "v1.1.1.4".
  • cybox_git_repo- Git url of the CyBox repository. By default "https://github.com/CybOXProject/python-cybox.git".
  • cybox_git_tag- Version of the CyBox module. By default "v2.1.0.12".
  • timezone- Timezone where the instance has been placed. By default "UTC".
  • default_user- User as which to run the installation of MISP. By default apache.
  • default_group- Group as which to run the installation of MISP. By default apache.
  • default_high_user- In some cases root permissions are need in the installation, this user will be used in those cases. By default root.
  • default_high_group- In some cases root permissions are need in the installation, this group will be used in those cases. By default apache.
  • uuid - The MISP instance UUID. This UUID is used to identify this instance. By default set to 0.

Database configuration

  • db_name - Name of the database. By default "misp".
  • db_user - Name of the user with rights on the database. By defeault "misp".
  • db_host - Name of the host in which the database is located. By default "localhost".
  • db_port - Port to connect to the database in the specified host. By default 3306.
  • db_password - Password used to access the database. By default is empty.

This module does not install the MariaDB server. However, if that was needed it could be done, in your manifest, in a similar manner as the following puppet fragment:

  $mysql_passwd = mysql_password('mispdb')

  class {'mariadb::server':
    root_password => 'mispdb',
    users                         => {
      'misp@localhost' => {
        ensure                   => 'present',
        max_connections_per_hour => '0',
        max_queries_per_hour     => '0',
        max_updates_per_hour     => '0',
        max_user_connections     => '0',
        password_hash            => $mysql_passwd,
        tls_options              => ['NONE'],
      },
    },
    grants => {
      'misp@localhost/misp.*' => {
        ensure     => 'present',
        options    => ['GRANT'],
        privileges => ['ALL'],
        table      => 'misp.*',
        user       => 'misp@localhost',
      },
      'misp@localhost/*.*' => {
        ensure     => 'present',
        options    => ['GRANT'],
        privileges => ['USAGE'],
        table      => '*.*',
        user       => 'misp@localhost',
        options    => "IDENTIFIED BY ${$mysql_passwd}",
      },
    },
    databases   => {
      'misp'  => {
        ensure  => 'present',
        charset => 'utf8',
      },
    },
  }

Note that it requires the edestecd-mariadb module.

Redis

GnuPG

To set up GPG fist you need to generate a gpg key with:

gpg --gen-key

Note that the email should be the email set up in the GnuPG part of the configuration (gpg_email parameter), and the same applies for the password (gpg_password parameter). There are known cases of errors when using it with a password (instead of passwordless as in the default configuration). If it gives an error run is as root.

Then move the key to the directory set up as home directory (gpg_homedir parameter), set apache as owner and group and the selinux context httpd_sys_rw_content_t.

mv ~/.gnupg /var/www/MISP/
chown -R apache:apache /var/www/MISP/.gnupg
chcon -R -t httpd_sys_rw_content_t /var/www/MISP/.gnupg

Finally export the public key to the webroot

sudo -u apache gpg --homedir /var/www/MISP/.gnupg --export --armor YOUR-EMAIL > /var/www/MISP/app/webroot/gpg.asc
