Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Cyber Security (CYBER). The present document is part 1 of a multi-part deliverable covering the Critical Security

18、Controls for Effective Cyber Defence, as identified below: Part 1: “The Critical Security Controls“; Part 2: “Measurement and auditing“; Part 3: “Service Sector Implementations“; Part 4: “Facilitation Mechanisms“. Modal verbs terminology In the present document “should“, “should not“, “may“, “need n

19、ot“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Executive summary The present docum

20、ent captures and describes the top twenty Enterprise industry level cybersecurity best practices that provide enhanced cyber security, developed and maintained by the Center for Internet Security (CIS) (formerly the Council on CyberSecurity) as an independent, expert, global non-profit organization.

21、 The CIS provides ongoing development, support, adoption, and use of the Critical Security Controls i.1. The Controls reflect the combined knowledge of actual attacks and effective defences of experts from every part of the cyber security ecosystem. This ensures that the Controls are an effective an

22、d specific set of technical measures available to detect, prevent, respond, and mitigate damage from the most common to the most advanced of those attacks. The Controls are not limited to blocking the initial compromise of systems, but also address detecting already-compromised machines and preventi

23、ng or disrupting attackers follow-on actions. The defences identified through these Controls deal with reducing the initial attack surface by hardening device configurations, identifying compromised machines to address long-term threats inside an organizations network, disrupting attackers command-a

24、nd-control of implanted malicious code, and establishing an adaptive, continuous defence and response capability that can be maintained and improved. The five critical tenets of an effective cyber defence system as reflected in the Critical Security Controls are: Offense informs defence: Use knowled

25、ge of actual attacks that have compromised systems to provide the foundation to continually learn from these events to build effective, practical defences. Include only those controls that can be shown to stop known real-world attacks. ETSI ETSI TR 103 305-1 V2.1.1 (2016-08)5 Prioritization: Invest

26、first in Controls that will provide the greatest risk reduction and protection against the most dangerous threat actors, and that can be feasibly implemented in a computing environment. Metrics: Establish common metrics to provide a shared language for executives, IT specialists, auditors, and secur

27、ity officials to measure the effectiveness of security measures within an organization so that required adjustments can be identified and implemented quickly. Continuous diagnostics and mitigation: Carry out continuous measurement to test and validate the effectiveness of current security measures,

28、and to help drive the priority of next steps. Automation: Automate defences so that organizations can achieve reliable, scalable, and continuous measurements of their adherence to the Controls and related metrics. Introduction The evolution of cyber defence is increasingly challenging. Massive data

29、losses, theft of intellectual property, credit card breaches, identity theft, threats to privacy, denial of service - these have become endemic. Access exists to an extraordinary array of security tools and technology, security standards, training and classes, certifications, vulnerability databases

30、, guidance, best practices, catalogues of security controls, and countless security checklists, benchmarks, and recommendations. But all of this technology, information, and oversight has become a veritable “Fog of More:“ competing options, priorities, opinions, and claims that can paralyze or distr

31、act an enterprise from vital action. Business complexity is growing, dependencies are expanding, users are becoming more mobile, and the threats are evolving. New technology brings great benefits, but it also means that data and applications are now distributed across multiple locations, many of whi

32、ch are not within the organizations infrastructure. In this complex, interconnected world, no enterprise can think of its security as a standalone problem. Focus is needed to establish priority of action, collective support, and keeping knowledge and technology current in the face of rapidly evolvin

33、g problems and an apparently infinite number of possible solutions. The most critical areas need to be addressed and the first steps taken toward maturing risk management programs. This includes a roadmap of fundamentals, and guidance to measure and improve the implementation defensive steps that ha

34、ve the greatest value. These issues led to, and drive, the Critical Security Controls. The value is determined by knowledge and data - the ability to prevent, alert, and respond to the attacks that are plaguing enterprises today. Initiating Implementation Some of the Critical Security Controls, in p

35、articular CSC 1 through CSC 5, are foundational, and are the primary recommended actions to be taken. This is the approach taken by, for example, the DHS Continuous Diagnostic and Mitigation (CDM) Program. A similar approach is recommended by the Australian Signals Directorate (ASD) with their “Top

36、Four Strategies to Mitigate Targeted Intrusions“ - a well-regarded and demonstrably effective set of cyber-defense actions that map very closely into the CIS Critical Security Controls.
