The Core outlines five key cybersecurity functions—Identify, Protect, Detect, Respond, and Recover—each of which is further divided into specific categories and subcategories. These functions offer a high-level, outcome-driven approach to managing cybersecurity risks.
The FIPS 140 standard established the Cryptographic Module Validation Program (CMVP) as a joint effort by the NIST and the Communications Security Establishment (CSEC) for the Canadian government, now handled by the CCCS, the Canadian Centre for Cyber Security, a new centralized initiative within the CSEC agency.
NIST's approach emphasizes a risk-based methodology, focusing on five core functions: Identify, Protect, Detect, Respond, and Recover. These principles form the backbone of many of its guidelines and frameworks, enabling organizations to assess and manage cybersecurity risks effectively.
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.
The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA". It was ...
NIST Special Publication 800-53 is an information security standard that provides a catalog of privacy and security controls for information systems.Originally intended for U.S. federal agencies except those related to national security, since the 5th revision it is a standard for general usage.
In the asymptotic setting, a family of deterministic polynomial time computable functions : {,} {,} for some polynomial p, is a pseudorandom number generator (PRNG, or PRG in some references), if it stretches the length of its input (() > for any k), and if its output is computationally indistinguishable from true randomness, i.e. for any probabilistic polynomial time algorithm A, which ...
The function has the same security properties as any (cryptographically secure) pseudorandom function. Specifically it shall be hard to distinguish the output from true randomness. The function is called an Oblivious Pseudorandom Function, because the second-party is oblivious to the function's output. This party learns no new information from ...
