misp-compliance

Legal, procedural and policies document templates for operating MISP and information sharing communities following existing regulations, laws or policies.

This repository is a collaborative effort to improve the state of information sharing and exchange within and outside the MISP Project.

Information sharing and cooperation enabled by GDPR

The General Data Protection Regulation (GDPR) aims to reduce legal uncertainty and limits the interpretations by setting out clear rules and conditions for the processing and sharing of personal data as well as the protection of natural persons with regard to the processing of personal data. Organisations must ensure that they process only the minimum amount of personal data necessary to achieve their lawful processing purposes. To this end, the GDPR distinguishes the roles and obligations of data processors and data controllers, provides precise definitions of personal data and establishes the conditions under which information can be shared.

National and governmental Computer Security Incident Response Team (n/g CSIRTs) are teams that serve the government of a country by helping with Critical Information Infrastructure Protection (CIIP). They coordinate incident management with the relevant stakeholders at national level, and cooperate with the national and governmental teams in other countries.

The Malware Information Sharing and Threat Intelligence Sharing Platform (MISP) is a software for sharing, storing and correlating indicators of compromise of targeted attacks, cybersecurity threats and financial fraud indicators, among which SHA1 hashes (a cryptographic function to fingerprint files), threat actor names and Bitcoin addresses. The MISP data model is composed of "events", which usually represent threats or incidents, which in turn are composed of a list of "attributes" (e.g. IP addresses, domain names etc..). Other data models exist in MISP such as "objects", which allow advanced combinations of attributes and "galaxies" which enable a deeper analysis and categorisation of events.

Information sharing communities are enabled using tools like MISP. As a Computer Security Incident Response Team for the private sector communes and non-governmental entities in Luxembourg, CIRCL has created and operates several communities to automate information sharing at national, European and international levels.

Information sharing enabled by DORA

The Digital Operational Resilience Act (DORA) is a new EU legislation aiming at improving the operational and cyber resilience of the Union's financial sector. Set to enter into application in early 2025, DORA will apply to a very wide range of entities, which will benefit from new provisions on information sharing. Those provisions will reinforce the legal grounds for information sharing arrangements on cyber threat information and intelligence.

MISP as supporting platform for sharing information, following ISO/IEC 27010:2015

Threat intelligence sharing comes with its own caveats and presents a few challenges. For example, organisations may end up with raw, unevaluated data, which adds an extra burden to the security team of the organisations by increasing the number of events and alerts rather than decreasing them. Moreover, some security vendors loath to share information to avoid losing the competitive edge.

Some of these issues are dealt by the ISO/IEC 27000-series (also known as the 'ISMS Family of Standards' or 'ISO27k' for short) of standards. It comprises information security standards published jointly by the International Organisation for Standardisation (ISO) and the International Electro technical Commission (IEC). The ISO/IEC 27000 series of standards provides best practice recommendations on information security management. The series is deliberately broad in scope, covering more than just privacy, confidentiality and cybersecurity issues. It is applicable to organisations of all shapes and sizes. All organisations are encouraged to assess their information risks, then treat them according to their needs, using the guidance and suggestions where relevant (typically using information security controls).

One of such standards is ISO/IEC 27010:2015, covering ‘Information security management for inter-sector and inter-organisational communications’, a supplement to ISO/IEC 27001:2013 and ISO/IEC 27002:2013 for use by information sharing communities.

Standard ISO/IEC 27010 (hereafter, the standard) is particularly relevant for MISP because it provides controls and guidance specifically relating to initiating, implementing, maintaining, and improving information security in inter-organisational and inter-sector communications. Moreover, it provides guidelines and general principles on how the specified requirements can be met using established messaging and other technical methods.

The standard is applicable to all forms of exchange and sharing of sensitive information, both public and private, nationally and internationally, within the same industry or market sector or between sectors. In particular, it may be applicable to information exchanges and sharing relating to the provision, maintenance and protection of an organisation or nation state's critical infrastructures. It is designed to support the creation of trust when exchanging and sharing sensitive information, thereby encouraging the international growth of information sharing communities.

How MISP enables stakeholders identified by the NISD to perform key activities

Network and Information Security (NIS) means ‘the ability of a network or an information system to resist accidental events or unlawful or malicious actions that compromise the availability, authenticity, integrity and confidentiality of data and the related services’ . The Directive on security of network and information systems (NISD) lays down specific obligations for Member States of the EU to adopt a national NIS strategy, to designate National Competent Authorities (NCA), Single Points of Contact (SPoC) and specific NIS tasks to Computer Security Incident Response Teams (CSIRTs). In addition, the NIS Directive establish es security and incident notification requirements for Operators of Essential Services (OES) such as banking, energy, financial market infrastructure, digital infrastructure; and Digital Service Providers (DSP), including online marketplaces, online search engines and cloud services. Furthermore, it creates a cooperation group in order to develop trust amongst MSs and facilitate strategic cybersecurity information sharing. In parallel, it creates a CSIRTs network to build confidence amongst MSs to boost operational cybersecurity cooperation.

The Malware Information Sharing and Threat Intelligence Sharing Platform (MISP) is an open source tool which primary purpose is to share cyber threat intelligence. It is broadly used in the CSIRTs community in the EU and beyond. It can be used for many other activities in addition to share cyber threat intelligence. Therefore, this article takes a closer look at how MISP can support stakeholders mentioned in the NISD to better perform the tasks identified therein. Especially CSIRTs, OESs and DSPs are the stakeholders that could benefit the most from using MISP in the scope of the NISD. Member States and Single Point of Contacts could also use MISP for the performance of their tasks, especially as a tool to receive and share NIS events and notify NIS incidents.

Guidelines to setting up an information sharing community such as an ISAC or ISAO

The objective of this guideline (this document) is to describe the practical aspects of setting up a new information sharing community, such as an Information Sharing and Analysis Centre (ISAC) or an Information Sharing and Analysis Organisation (ISAO). In this guideline, we will refer to individuals or organisations that intend to set up a sharing community as "you" or the "operator".

Relevant research has already been conducted and published by organisations such as the European Union Agency for Network and Information Security (ENISA) and the ISAO Standards Organisation. Our guideline provides practical best practices to set up an information sharing community based on feedback and experience from existing information sharing communities.

This guideline is focused around the Open Source Threat Intelligence Sharing platform (MISP) used in support on information sharing activities.
