INSTALLATION INSTRUCTIONS for RHEL 7.x and CentOS 7.x


-1/ Installer and Manual install instructions

Make sure you are reading the parsed version of this Document. When in doubt click here.

Warning

In the future, to install MISP on a fresh RHEL 7 install all you need to do is:

# Please check the installer options first to make the best choice for your install
wget -O /tmp/INSTALL.sh https://raw.githubusercontent.com/MISP/MISP/2.4/INSTALL/INSTALL.sh
bash /tmp/INSTALL.sh

# This will install MISP Core
wget -O /tmp/INSTALL.sh https://raw.githubusercontent.com/MISP/MISP/2.4/INSTALL/INSTALL.sh
bash /tmp/INSTALL.sh -c
The above does NOT work yet

0/ Overview and Assumptions

Notice

There are technically only minor differences between CentOS and RHEL.
For more information on what might differ, this StackExchange question might answer some questions.

Warning

The core MISP team cannot verify if this guide is working or not. Please help us in keeping it up to date and accurate. Thus we also have difficulties in supporting RHEL issues but will do a best effort on a similar yet slightly different setup.

Notice

Maintenance for CentOS 7 will end on: June 30th, 2024 Source[0] Source[1] CentOS 7-1908 NetInstallURL

This document details the steps to install MISP on Red Hat Enterprise Linux 7.x (RHEL 7.x) and CentOS 7.x. At time of this writing it was tested on versions 7.6 for both. This is a joint RHEL/CentOS install guide. The authors tried to make it contextually evident what applies to which flavor.

The following assumptions with regard to this installation have been made.

  • A valid support agreement allowing the system to register to the Red Hat Customer Portal and receive updates
  • The ability to enable additional RPM repositories, specifically the EPEL and Software Collections (SCL) repos
  • This system will have direct or proxy access to the Internet for updates. Or connected to a Red Hat Satellite Server
  • This document will bootstrap a MISP instance running over HTTPS. A full test of all features have yet to be done. The following GitHub issue details some shortcomings.

Note

For fresh installs the following tips might be handy.
Allow ssh to pass the firewall on the CLI

firewall-cmd --zone=public --add-port=22/tcp --permanent
firewall-cmd --reload

To quickly make sure if NetworkManager handles your network interface on boot, check in the following location:
/etc/sysconfig/network-scripts/ifcfg-*

1/ OS Install and additional repositories

1.1/ Complete a minimal RHEL/CentOS installation, configure IP address to connect automatically.

1.2/ Configure system hostname (if not done during install)

sudo hostnamectl set-hostname misp.local # Your choice, in a production environment, it's best to use a FQDN

1.3/ [RHEL] Register the system for updates with Red Hat Subscription Manager

# <snippet-begin 0_RHEL_register.sh>
sudo subscription-manager register --auto-attach # register your system to an account and attach to a current subscription
# <snippet-end 0_RHEL_register.sh>

1.4/ [RHEL] Enable the optional, extras and Software Collections (SCL) repos

# <snippet-begin 0_RHEL_SCL.sh>
enableReposRHEL () {
  sudo subscription-manager refresh
  sudo subscription-manager repos --enable rhel-7-server-optional-rpms
  sudo subscription-manager repos --enable rhel-7-server-extras-rpms
  sudo subscription-manager repos --enable rhel-server-rhscl-7-rpms
}
# <snippet-end 0_RHEL_SCL.sh>

1.4c/ [CentOS] Enable EPEL for additional dependencies

# <snippet-begin 0_CentOS_EPEL.sh>
centosEPEL () {
  # We need some packages from the Extra Packages for Enterprise Linux repository
  sudo yum install epel-release -y

  # Since MISP 2.4 PHP 5.5 is a minimal requirement, so we need a newer version than CentOS base provides
  # Software Collections is a way do to this, see https://wiki.centos.org/AdditionalResources/Repositories/SCL
  sudo yum install centos-release-scl -y
}
# <snippet-end 0_CentOS_EPEL.sh>

1.5a/ Install the deltarpm package to help reduce download size when installing updates (optional)

sudo yum install deltarpm -y

1.5.b/ Install vim (optional)

# Because (neo)vim is just so practical
sudo yum install neovim -y

1.5.c/ Install ntpdate (optional)

# In case you time is wrong, this will fix it.
sudo yum install ntpdate -y
sudo ntpdate pool.ntp.org

1.5/ Update the system and reboot

# <snippet-begin 0_yum-update.sh>
yumUpdate () {
  sudo yum update -y
}
# <snippet-end 0_yum-update.sh>

1.6/ [RHEL] Install the EPEL repo

# <snippet-begin 0_RHEL_EPEL.sh>
enableEPEL () {
  sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm -y
}
# <snippet-end 0_RHEL_EPEL.sh>

2/ Dependencies

Note

This guide installs PHP 7.2 from SCL

Warning

PHP 5.6 and 7.0 aren't supported since December 2018. Please update accordingly. In the future only PHP7 will be supported.

2.01/ Install some base system dependencies

# <snippet-begin 0_yumInstallCoreDeps.sh>
yumInstallCoreDeps () {
  # Install the dependencies:
  sudo yum install gcc git zip rh-git218 \
                   httpd24 \
                   mod_ssl \
                   rh-redis32 \
                   rh-mariadb102 \
                   libxslt-devel zlib-devel ssdeep-devel -y

  # Enable and start redis
  sudo systemctl enable --now rh-redis32-redis.service

  WWW_USER="apache"
  SUDO_WWW="sudo -H -u $WWW_USER"
  RUN_PHP="/usr/bin/scl enable rh-php72"
  PHP_INI="/etc/opt/rh/rh-php72/php.ini"
  # Install PHP 7.2 from SCL, see https://www.softwarecollections.org/en/scls/rhscl/rh-php72/
  sudo yum install rh-php72 rh-php72-php-fpm rh-php72-php-devel \
                   rh-php72-php-mysqlnd \
                   rh-php72-php-mbstring \
                   rh-php72-php-xml \
                   rh-php72-php-bcmath \
                   rh-php72-php-opcache \
                   rh-php72-php-gd -y

  # Python 3.6 is now available in RHEL 7.7 base
  sudo yum install python3 python3-devel -y

  sudo systemctl enable --now rh-php72-php-fpm.service
}
# <snippet-end 0_yumInstallCoreDeps.sh>

Notice

$RUN_PHP makes php available for you if using rh-php72. e.g: sudo $RUN_PHP "pear list | grep Crypt_GPG"

# <snippet-begin 0_yumInstallHaveged.sh>
# GPG needs lots of entropy, haveged provides entropy
# /!\ Only do this if you're not running rngd to provide randomness and your kernel randomness is not sufficient.
sudo yum install haveged -y
sudo systemctl enable --now haveged.service
# <snippet-end 0_yumInstallHaveged.sh>

Warning

If you have installed the recommended Python 3 virtualenv to the recommended place of ${PATH_TO_MISP}/venv set the following MISP configurable

sudo -H -u www-data $CAKE Admin setSetting "MISP.python_bin" "${PATH_TO_MISP}/venv/bin/python"
or on CentOS
sudo -u apache $RUN_PHP "$CAKE Admin setSetting "MISP.python_bin" "${PATH_TO_MISP}/venv/bin/python""

Warning

Make sure that the STIX libraries and GnuPG work as intended, if not, refer to the relevant sections in the install guide you are currently reading.

Notice

Now log in using the webinterface: http://misp/users/login
The default user/pass = admin@admin.test/admin
Using the server settings tool in the admin interface (Administration -> Server Settings), set MISP up to your preference.
It is especially vital that no critical issues remain!
Don't forget to change the email, password and authentication key after installation.
Once done, have a look at the diagnostics.

Notice

If any of the directories that MISP uses to store files is not writeable to the apache user, change the permissions
you can do this by running the following commands:

chmod -R 750 ${PATH_TO_MISP}/<directory path with an indicated issue>
# /!\ Depending on your OS replace www-data with apache or www or whatever user is the web server user.
chown -R www-data:www-data ${PATH_TO_MISP}/<directory path with an indicated issue>

Notice

If anything goes wrong, make sure that you check MISP's logs for errors:

# ${PATH_TO_MISP}/app/tmp/logs/error.log
# ${PATH_TO_MISP}/app/tmp/logs/resque-worker-error.log
# ${PATH_TO_MISP}/app/tmp/logs/resque-scheduler-error.log
# ${PATH_TO_MISP}/app/tmp/logs/resque-2018-10-25.log //where the actual date is the current date


  • By default CakePHP exposes its name and version in email headers. Apply a patch to remove this behavior.

  • You should really harden your OS

  • You should really harden the configuration of Apache
  • You should really harden the configuration of MySQL
  • Keep your software up2date (MISP, CakePHP and everything else)
  • Log and audit

11/ LIEF Installation

lief is required for the Advanced Attachment Handler and requires manual compilation

The installation is explained in section 3.01

12/ Known Issues

12.01/ Workers cannot be started or restarted from the web page

Possible also due to package being installed via SCL, attempting to start workers through the web page will result in error. Worker's can be restarted via the CLI using the following command.

systemctl restart misp-workers.service

Note

No other functions were tested after the conclusion of this install. There may be issue that aren't addressed
via this guide and will need additional investigation.

Hardening a base system

Intro

MISP is a web-based information sharing platform, by design it is kept rather simple and hardening can be done by following the common best practices.

Bare in mind that neither the MISP documentation efforts or the core MISP project can give you the ultimate guide on how to harden your system. This is not the purpose of the MISP Project but the purpose and care of those individuals and organizations deploying MISP Instances.

Nevertheless here is a very rough food for thoughts bulletpoint list for you to consider, and a list of some hardening ressources below.

  • Are we using SSL by default? (Especially when syncing over the internet and exposing the API)
  • How to we access the machine remotely? Via ssh? What is the path to get there? Does a bastion host make sense?
  • Is the machine shared with other user accounts? Do I need to care about useri-land security due to this sharing?
  • Is the instance deployed in the "cloud"? Is it a VPS? AWS? docker? ansible? kubernetes? whateverCloudContainterMagicIsFancibleNow?
  • Do we need to encrypt the partitions where some data is stored?
  • Are we redundant in case one MISP instance might fail?
  • Is the database server and any other servers running on the machine bound to localhost? Do we need to expose because our setup is more complex?
  • Do we have enough storage? What about MISP and size estimation anyways?
  • Do we care about BIOS updates?
  • Do we care about physical access to the servers? (Disabling USB ports etc...)
  • Is any fancy management engine à la IME in use?

Apache

To make Apache less verbose in terms of sending banners, the belo might help.
