In today's interconnected digital world, organizations face a constant barrage of cyber threats. To effectively defend against these threats, it is crucial to have a robust platform for sharing and analyzing threat intelligence. MISP (Malware Information Sharing Platform) is an open source solution that fills this need. Developed by a group of cybersecurity professionals, MISP provides a centralized platform for collecting, storing, and sharing indicators of compromise (IOCs) and threat data among trusted partners and communities.

What is MISP?

MISP is an open source threat intelligence platform that enables organizations to share, store, and correlate IOCs of targeted attacks, threat intelligence, financial fraud information, vulnerability data, and more. It serves as a centralized knowledge base where incident responders, security analysts, and researchers can collaborate on analyzing malware, attacks, and threats.

MISP's primary goal is to foster information sharing among cybersecurity teams and improve the detection and prevention of attacks against IT infrastructures, organizations, and people. By providing a structured format for storing technical and non-technical data, MISP enables the automation of IOC processing and integration with other security tools such as IDS, SIEM, and malware analysis platforms.

Key Features

MISP offers a comprehensive set of features designed to streamline threat intelligence management:

  • Flexible data model for expressing complex threat data and relationships

  • Automatic correlation engine to identify relationships between IOCs

  • Built-in sharing functionality with fine-grained distribution control

  • Intuitive web interface for creating, updating, and collaborating on events

  • Customizable taxonomies and tagging schemes for event classification

  • Export capabilities to generate IDS rules, OpenIOC, STIX, and other formats

  • Import functionality supporting various formats and feed integration

  • REST API for integration with other tools and platforms

  • Sighting support to track the observations of shared IOCs

  • Integrated PGP and S/MIME encryption for secure notifications

Who Can Use MISP?

MISP is designed to cater to a wide range of users within the cybersecurity community:

  • CERTs and CSIRTs

  • Security Operations Centers (SOCs)

  • Incident Response Teams

  • Threat Intelligence Analysts

  • Malware Researchers

  • Law Enforcement Agencies

  • Government Institutions

  • Private Sector Companies

  • Academic and Research Institutions

Whether you are part of a small security team or a large-scale international organization, MISP can be tailored to meet your threat intelligence sharing and collaboration needs.

Supported Platforms

MISP is a cross-platform solution that can be deployed on various operating systems:

  • Linux (recommended for production use)

  • macOS

  • Windows

The platform is built using open source technologies such as Python, PHP, and MySQL/MariaDB, ensuring compatibility and ease of installation across different environments.

How to Install MISP?

To install MISP, follow these step-by-step instructions:

  1. Choose your platform: MISP can be installed on Linux, macOS, or Windows. For production use, Linux (Ubuntu or CentOS/RHEL) is recommended.

  2. Prerequisites: Ensure that your system meets the minimum requirements for MISP, including a web server (Apache or Nginx), PHP, Python, and MySQL/MariaDB.

  3. Download MISP: Clone the MISP repository from GitHub or download the latest release archive from the official website.

  4. Install dependencies: Run the provided shell script to install the required dependencies for your operating system. For example, on Ubuntu, run:sudo apt-get install -y curl gcc git gnupg-agent make python openssl redis-server sudo vim zip

  5. Configure MySQL/MariaDB: Set up a MySQL or MariaDB database for MISP. Create a database and a user with appropriate permissions.

  6. Configure PHP: Install and configure PHP and its required modules. Ensure that the PHP command-line interface is working correctly.

  7. Install MISP core: Navigate to the MISP directory and run the following commands to install the MISP core components:git submodule update --init --recursivegit submodule foreach git checkout mastergit submodule foreach git pull

  8. Configure MISP: Copy the default configuration files and modify them to match your environment. Set up the database connection, server settings, and security keys.

  9. Install MISP modules: Install any additional MISP modules required for your specific use case. Modules can be installed using the MISP modules manager.

  10. Secure your installation: Configure your web server to use HTTPS and set up appropriate access controls. Regularly update MISP and its dependencies to ensure the latest security patches are applied.

  11. Test your installation: Access the MISP web interface and verify that everything is working correctly. Create a test event and ensure that data is being stored and retrieved properly.

For detailed installation instructions specific to your operating system and environment, refer to the official MISP installation guide and documentation.

How to Use MISP?

Using MISP involves interacting with the web interface and, optionally, the API. Here are some common tasks and their corresponding commands:

  1. Access MISP: Open a web browser and navigate to your MISP instance's URL. Log in using your username and password.

  2. Create an event:

    • Click on the "Add Event" button in the top menu.

    • Fill in the required fields, such as the event info, date, and threat level.

    • Add attributes and attachments as needed.

    • Click "Submit" to create the event.

  3. Add an attribute to an event:

    • Navigate to the event you want to update.

    • Click on the "Add Attribute" button.

    • Select the attribute type, enter the value, and set any additional properties.

    • Click "Submit" to add the attribute to the event.

  4. Create a sharing group:

    • Click on the "Add Sharing Group" button in the top menu.

    • Enter a name and description for the sharing group.

    • Select the organizations that should be part of the group.

    • Click "Submit" to create the sharing group.

  5. Publish an event:

    • Navigate to the event you want to publish.

    • Click on the "Publish Event" button.

    • Select the distribution level and sharing group, if applicable.

    • Click "Submit" to publish the event.

  6. Use the API:

    • MISP provides a comprehensive REST API for automation and integration.

    • To use the API, you'll need to generate an API key in your user profile settings.

    • Examples of API commands:

      • Get an event: curl -H "Authorization: <API_KEY>" https://<MISP_URL>/events/<EVENT_ID>

      • Add an attribute: curl -H "Authorization: <API_KEY>" -H "Content-Type: application/json" -d '{"type":"domain","value":""}' https://<MISP_URL>/attributes/add/<EVENT_ID>

      • Publish an event: curl -H "Authorization: <API_KEY>" -H "Content-Type: application/json" -d '{"id":<EVENT_ID>}' https://<MISP_URL>/events/publish

  7. Explore the user manual:

    • MISP provides a comprehensive user manual with detailed instructions and screenshots.

    • Access the user manual by clicking on the "User Manual" link in the top menu of your MISP instance.

Remember to replace <API_KEY>, <MISP_URL>, and <EVENT_ID> with your actual API key, MISP instance URL, and event ID, respectively, when using the API commands.

For more advanced usage and specific workflows, refer to the MISP user manual and the API documentation available on your MISP instance.
