Rivest-Shamir-Adleman (RSA)
Algorithm developed by Rivest, Shamir and Adelman (allowed in FIPS 186-3 and specified in ANS X9.31 and PKCS #1).See NIST SP 800-89 under RSA for ...
Radio Frequency (RF) Jamming
A threat in which an adversary introduces a powerful RF signal to overwhelm the spectrum being used by the system, thus denying service to all ...
Random Number
For the purposes of this recommendation, a value in a set that has an equal probability of being selected from the total population of possibilities ...
Random Number Generator
A process used to generate an unpredictable series of numbers. Also called a Random bit generator (RBG). See NIST SP 800-57 Part 1 Rev. 4 under Random number ...
Read-Only Memory
ROM is a pre-recorded storage medium that can only be read from and not written to. See NIST SP 800-88 Rev. 1 for more detailed information.
Recovery Point Objective
The point in time to which data must be recovered after an outage. See NIST SP 800-34 Rev. 1 for more detailed information.
Remote Access
Access to an organizational information system by a user (or an information system) communicating through an external, non-organization-controlled network (e.g., the Internet). See the following for ...
Remote Access Server
Devices, such as virtual private network gateways and modem servers, that facilitate connections between networks. See NIST SP 800-86 for more information.
Replay Attacks
An attack in which the Attacker is able to replay previously captured messages (between a legitimate Claimant and a Verifier) to masquerade as that Claimant ...
Risk Assessment
The process of identifying risks to organizational operations (including mission, functions, image, reputation), organizational assets, individuals, other organizations, and the Nation, resulting from the operation ...
Risk Management
The process of managing risks to organizational operations (including mission, functions, image, or reputation), organizational assets, or individuals resulting from the operation of an information ...
Risk Mitigation
Prioritizing, evaluating, and implementing the appropriate risk-reducing controls/countermeasures recommended from the risk management process. A subset of Risk Response. See the following under Risk Mitigation for ...
Risk Response
Accepting, avoiding, mitigating, sharing, or transferring risk to organizational operations (mission, functions, image, or reputation), organizational assets, individuals, other organizations, and the Nation. See the following ...
