NIST Special Publication 800-63 of June 2004 (revision two) suggested a scheme to approximate the entropy of human-generated passwords: [4] Using this scheme, an eight-character human-selected password without uppercase characters and non-alphabetic characters OR with either but of the two character sets is estimated to have eighteen bits of ...
The Worst Passwords List is an annual list of the 25 most common passwords from each year as produced by internet security firm SplashData. [4] Since 2011, the firm has published the list based on data examined from millions of passwords leaked in data breaches, mostly in North America and Western Europe, over each year.
A password policy is a set of rules designed to enhance computer security by encouraging users to employ strong passwords and use them properly. A password policy is often part of an organization's official regulations and may be taught as part of security awareness training. Either the password policy is merely advisory, or the computer ...

The easier a password is for the owner to remember generally means it will be easier for an attacker to guess. [12] However, passwords that are difficult to remember may also reduce the security of a system because (a) users might need to write down or electronically store the password, (b) users will need frequent password resets and (c) users are more likely to re-use the same password ...
NIST replaced these codes with the more permanent GNIS Feature ID, maintained by the U.S. Board on Geographic Names. The GNIS database is the official geographic names repository database for the United States, and is designated the only source of geographic names and locative attributes for use by the agencies of the Federal Government.

A complete set of the US DoD Rainbow Series computer security documents. The Rainbow Series (sometimes known as the Rainbow Books) is a series of computer security standards and guidelines published by the United States government in the 1980s and 1990s.
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 ...
