INSTALLATION INSTRUCTIONS

for CentOS 6.10

-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 CentOS 6 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/ MISP CentOS 6 Minimal NetInstall - Status


Notice

Maintained and tested by the community.
Parts of the installation procedures can also be found in the automatic VM generator script bootstrap.sh of misp-packer.

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.

Notice

Semi-maintained and tested by @SteveClement, CentOS 6.10 on 20190417
It is still considered experimental as not everything works seemlessly.

Notice

Maintenance will end on: November 30th, 2020 Source[0] Source[1]

1/ Minimal CentOS install


Install a minimal CentOS 6.x system with the software:

  • OpenSSH server
  • LAMP server (actually, this is done below)
  • Mail server
# Make sure you set your hostname CORRECTLY vs. like an brute (manually in /etc/hostname)
sudo hostnamectl set-hostname misp.local # Your choice, in a production environment, it's best to use a FQDN

# Make sure your system is up2date:
sudo yum update -y

2/ Dependencies *


Once the system is installed you can perform the following steps as root or with sudo.

# We need some packages from the Extra Packages for Enterprise Linux repository
curl -o /tmp/epel.rpm http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
sudo rpm -Uvh /tmp/epel.rpm

# php 7.2
# sudo rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
# sudo yum install yum-utils
# sudo yum-config-manager --enable remi-php72
# sudo yum update


# 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

# Because vim is just so practical
sudo yum install vim -y

# Install the dependencies:
sudo yum install gcc git zip \
       httpd \
       mod_ssl \
       redis \
       mysql-server \
       python-devel python-pip python-zmq \
       libxslt-devel zlib-devel ssdeep-devel -y

# Install PHP 7.0 from SCL, see https://www.softwarecollections.org/en/scls/rhscl/rh-php70/
sudo yum install rh-php70 rh-php70-php-fpm rh-php70-php-devel rh-php70-php-mysqlnd rh-php70-php-mbstring rh-php70-php-xml rh-php70-php-bcmath rh-php70-php-gd

# Install Python 3.6 from SCL, see https://www.softwarecollections.org/en/scls/rhscl/rh-python36/
sudo yum install rh-python36 -y

# rh-php70-php only provided mod_php for httpd24-httpd from SCL
# if we want to use httpd from CentOS base we can use rh-php70-php-fpm instead
sudo chkconfig rh-php70-php-fpm on
sudo service rh-php70-php-fpm start

# php-fpm is accessed using the fcgi interface
sudo yum install mod_fcgid mod_proxy_fcgi

Notice

$RUN_PHP makes php available for you if using rh-php70. e.g: $RUN_PHP "pear list | grep Crypt_GPG"

# GPG needs lots of entropy, haveged provides entropy
sudo yum install haveged -y
sudo chkconfig haveged on
sudo service haveged start

# Enable and start redis
sudo chkconfig redis on
sudo service redis start

4/ CakePHP


CakePHP is now included as a submodule of MISP and has been fetch by a previous step.

Install CakeResque along with its dependencies if you intend to use the built in background jobs.

sudo chown -R apache:apache $PATH_TO_MISP
sudo mkdir /var/www/.composer/
sudo chown apache:apache /var/www/.composer/
cd $PATH_TO_MISP/app
# Update composer.phar (optional)

#$SUDO_WWW $RUN_PHP "php composer-setup.php"
#$SUDO_WWW $RUN_PHP -- php -r "unlink('composer-setup.php');"
$SUDO_WWW $RUN_PHP "php composer.phar install"

sudo yum install php-redis -y
sudo service rh-php70-php-fpm restart

# If you have not yet set a timezone in php.ini
echo 'date.timezone = "Europe/Luxembourg"' |sudo tee /etc/opt/rh/rh-php70/php-fpm.d/timezone.ini
sudo ln -s ../php-fpm.d/timezone.ini /etc/opt/rh/rh-php70/php.d/99-timezone.ini

# Recommended: Change some PHP settings in /etc/opt/rh/rh-php70/php.ini
# max_execution_time=300
# memory_limit=2048M

do
    sudo sed -i "s/^\($key\).*/\1 = $(eval echo \${$key})/" $PHP_INI
done
sudo service rh-php70-php-fpm restart
# To use the scheduler worker for scheduled tasks, do the following:
sudo cp -fa $PATH_TO_MISP/INSTALL/setup/config.php $PATH_TO_MISP/app/Plugin/CakeResque/Config/config.php

5/ Set the permissions


# Make sure the permissions are set correctly using the following commands as root:
sudo chown -R apache:apache $PATH_TO_MISP
sudo find $PATH_TO_MISP -type d -exec chmod g=rx {} \;
sudo chmod -R g+r,o= $PATH_TO_MISP
sudo chmod -R 750 $PATH_TO_MISP
sudo chmod -R g+xws $PATH_TO_MISP/app/tmp
sudo chmod -R g+ws $PATH_TO_MISP/app/files
sudo chmod -R g+ws $PATH_TO_MISP/app/files/scripts/tmp
sudo chmod -R g+rw $PATH_TO_MISP/venv
sudo chmod -R g+rw $PATH_TO_MISP/.git
sudo chown apache:apache $PATH_TO_MISP/app/files
sudo chown apache:apache $PATH_TO_MISP/app/files/terms
sudo chown apache:apache $PATH_TO_MISP/app/files/scripts/tmp
sudo chown apache:apache $PATH_TO_MISP/app/Plugin/CakeResque/tmp
sudo chown -R apache:apache $PATH_TO_MISP/app/Config
sudo chown -R apache:apache $PATH_TO_MISP/app/tmp
sudo chown -R apache:apache $PATH_TO_MISP/app/webroot/img/orgs
sudo chown -R apache:apache $PATH_TO_MISP/app/webroot/img/custom

6/ Create a database and user


# Enable, start and secure your mysql database server
sudo chkconfig mysqld on
sudo service mysqld start
sudo yum install expect -y

# Add your credentials if needed, if sudo has NOPASS, comment out the relevant lines
pw="Password1234"

expect -f - <<-EOF
  set timeout 10

  spawn sudo mysql_secure_installation
  expect "*?assword*"
  send -- "$pw\r"
  expect "Enter current password for root (enter for none):"
  send -- "\r"
  expect "Set root password?"
  send -- "y\r"
  expect "New password:"
  send -- "${DBPASSWORD_ADMIN}\r"
  expect "Re-enter new password:"
  send -- "${DBPASSWORD_ADMIN}\r"
  expect "Remove anonymous users?"
  send -- "y\r"
  expect "Disallow root login remotely?"
  send -- "y\r"
  expect "Remove test database and access to it?"
  send -- "y\r"
  expect "Reload privilege tables now?"
  send -- "y\r"
  expect eof
EOF

sudo yum remove tcl expect -y

# Additionally, it is probably a good idea to make the database server listen on localhost only
echo [mysqld] |sudo tee /etc/my.cnf.d/bind-address.cnf
echo bind-address=127.0.0.1 |sudo tee -a /etc/my.cnf.d/bind-address.cnf
sudo service mysqld restart

Manual procedure:

# Enter the mysql shell
mysql -u root -p
mysql> create database misp;
mysql> grant usage on *.* to misp@localhost identified by 'XXXXXXXXX';
mysql> grant all privileges on misp.* to misp@localhost ;
mysql> exit

Same as Manual but for copy/paste foo:

sudo mysql -u $DBUSER_ADMIN -p$DBPASSWORD_ADMIN -e "create database $DBNAME;"
sudo mysql -u $DBUSER_ADMIN -p$DBPASSWORD_ADMIN -e "grant usage on *.* to $DBNAME@localhost identified by '$DBPASSWORD_MISP';"
sudo mysql -u $DBUSER_ADMIN -p$DBPASSWORD_ADMIN -e "grant all privileges on $DBNAME.* to '$DBUSER_MISP'@'localhost';"
sudo mysql -u $DBUSER_ADMIN -p$DBPASSWORD_ADMIN -e "flush privileges;"

Import the empty MySQL database from MYSQL.sql

$SUDO_WWW cat $PATH_TO_MISP/INSTALL/MYSQL.sql | mysql -u $DBUSER_MISP -p$DBPASSWORD_MISP $DBNAME

7/ Apache configuration


Notice

SELinux note, to check if it is running:

$ sestatus
SELinux status:                 disabled
If it is disabled, you can ignore the chcon/setsebool/semanage/checkmodule/semodule* commands.

# Now configure your apache server with the DocumentRoot $PATH_TO_MISP/app/webroot/
# A sample vhost can be found in $PATH_TO_MISP/INSTALL/old/apache.misp.centos6

sudo cp $PATH_TO_MISP/INSTALL/old/apache.misp.centos6 /etc/httpd/conf.d/misp.conf

# Allow httpd to connect to the redis server and php-fpm over tcp/ip
sudo setsebool -P httpd_can_network_connect on

# Enable and start the httpd service
sudo chkconfig httpd on
sudo service httpd start

# Open a hole in the iptables firewall
sudo iptables -I INPUT 5 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT
sudo service iptables save

# We seriously recommend using only HTTPS / SSL !
# Add SSL support by running: yum install mod_ssl
# Check out the apache.misp.ssl file for an example
# If a valid SSL certificate is not already created for the server, create a self-signed certificate:
sudo openssl req -newkey rsa:4096 -days 365 -nodes -x509 \
-subj "/C=${OPENSSL_C}/ST=${OPENSSL_ST}/L=${OPENSSL_L}/O=${OPENSSL_O}/OU=${OPENSSL_OU}/CN=${OPENSSL_CN}/emailAddress=${OPENSSL_EMAILADDRESS}" \
-keyout /etc/ssl/private/misp.local.key -out /etc/ssl/private/misp.local.crt

8/ Log rotation


# MISP saves the stdout and stderr of its workers in $PATH_TO_MISP/app/tmp/logs
# To rotate these logs install the supplied logrotate script:

sudo cp $PATH_TO_MISP/INSTALL/misp.logrotate /etc/logrotate.d/misp
sudo chmod 0640 /etc/logrotate.d/misp

# Now make logrotate work under SELinux as well
# Allow logrotate to modify the log files
sudo semanage fcontext -a -t httpd_log_t "$PATH_TO_MISP/app/tmp/logs(/.*)?"
sudo chcon -R -t httpd_log_t $PATH_TO_MISP/app/tmp/logs
sudo chcon -R -t httpd_sys_rw_content_t $PATH_TO_MISP/app/tmp/logs

# Allow logrotate to read /var/www
sudo checkmodule -M -m -o /tmp/misplogrotate.mod $PATH_TO_MISP/INSTALL/misplogrotate.te
sudo semodule_package -o /tmp/misplogrotate.pp -m /tmp/misplogrotate.mod
sudo semodule -i /tmp/misplogrotate.pp

9/ MISP configuration


# There are 4 sample configuration files in $PATH_TO_MISP/app/Config that need to be copied
$SUDO_WWW cp -a $PATH_TO_MISP/app/Config/bootstrap.default.php $PATH_TO_MISP/app/Config/bootstrap.php

#}

# Important! Change the salt key in $PATH_TO_MISP/app/Config/config.php

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

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.
