NIST Version 1.1. The NIST Cybersecurity Framework organizes its "core" material into five "functions" which are subdivided into a total of 23 "categories". For each category, it defines a number of subcategories of cybersecurity outcomes and security controls, with 108 subcategories in all.
The authors of Falcon provide a reference implementation in C as required by the NIST and one in Python for simplicity. The set of parameters suggested by Falcon imply a signature size of 666 bytes and a public key size of 897 bytes for the NIST security level 1 (security comparable to breaking AES-128 bits). The key generation can be performed ...
Published in September 2006, the NIST SP 800-92 Guide to Computer Security Log Management serves as a key document within the NIST Risk Management Framework to guide what should be auditable. As indicated by the absence of the term "SIEM", the document was released before the widespread adoption of SIEM technologies.
[1] [3] The RMF steps link to several other NIST standards and guidelines, including NIST Special Publication 800-53. The RMF process includes the following steps: Prepare to execute the RMF by establishing a context and setting priorities for managing security and privacy risk at both organizational and system levels.
The Gordon-Loeb model provides a framework for determining how much to invest in cybersecurity, using a cost-benefit approach. The model includes the following key components: Organizational data vulnerable to cyber-attacks, with vulnerability denoted by v (0 ≤ v ≤ 1), representing the probability of a breach occurring under current conditions.
An extension to the NIST Cybersecurity Framework is the Cybersecurity Maturity Model (CMMC) which was introduced in 2019 (though the origin of CMMC began with Executive Order 13556). [41] It emphasizes the importance of implementing Zero-trust architecture (ZTA) which focuses on protecting resources over the network perimeter.
Information security standards (also cyber security standards [1]) are techniques generally outlined in published materials that attempt to protect a user's or organization's cyber environment. [2] This environment includes users themselves, networks, devices, all software, processes, information in storage or transit, applications, services ...
Although it is not a standard, the NIST Cybersecurity Framework (NIST CSF) provides a high-level taxonomy of cybersecurity outcomes and a methodology to assess and manage those outcomes. It is intended to help private sector organizations that provide critical infrastructure with guidance on how to protect it.
