Routing Information Protocol (RIP)
The routing information protocol (RIP) defines a manner for routers to share information on how to route traffic among various networks. RIP is classified by the internet engineering task force (IETF) as an interior gateway protocol (IGP), one of several protocols for routers moving traffic around within a larger autonomous system network.

Regression Analysis
The use of scripted tests which are used to test software for all possible input is expected. Typically developers will create a set of regression tests that are executed before a new version of a software is released.

Reconnaissance
Reconnaissance is the phase of an attack where an attacker is able to locate new systems, map out several networks, and probe for specific vulnerabilities in the system or network. It is used to obtain information by either visual observation or other detection methods about the activities and resources of an attacker.

Request for Comments (RFC)
A request for comments (RFC) is a type of publication from the internet engineering task force (IETF) and the internet society. An RFC is authored by engineers and computer scientists in the form of a memorandum describing methods, behaviors, research, or innovations applicable to the working of the internet and internet-connected systems. RFC started in 1969, when the internet was the arpanet.

Rivest-Shamir-Adleman (RSA)
Rivest-Shamir-Adleman (RSA) is one of the first practical public-key cryptosystems and is widely used for secure data transmission. RSA is an algorithm for asymmetric cryptography, invented in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman. This is based on the practical difficulty of factoring the product of two large prime numbers, the factoring problem.

Reverse Lookup
The reverse lookup is used to locate the hostname that corresponds to a particular IP address. Reverse lookup uses an IP (internet protocol) address to find a domain name.

Risk
Risk is the probability of a system or network attack. Risk is the potential of losing valuable and sensitive information.
