Guard or guards may refer to:

Guard (computer science)

In computer programming, a guard is a boolean expression that must evaluate to true if the program execution is to continue in the branch in question.

Regardless of which programming language is used, guard code or a guard clause is a check of integrity preconditions used to avoid errors during execution. A typical example is checking that a reference about to be processed be not null, which avoids null-pointer failures. Other uses include using a boolean field for idempotence (so subsequent calls are nops), as in the dispose pattern. Guard code provides an early exit from a subroutine, and is a commonly used deviation from structured programming, removing one level of nesting and resulting in flatter code: replacing if guard { ... } with if not guard: return; ....

The term is used with specific meaning in Haskell, Clean, Erlang, occam, Promela, OCaml, Swift and Scala programming languages. In Mathematica, guards are called constraints. Guards are the fundamental concept in Guarded Command Language, a language in formal methods. Guards can be used to augment pattern matching with the possibility to skip a pattern even if the structure matches. Boolean expressions in conditional statements usually also fit this definition of a guard although they are called conditions.

In the following Haskell example, the guards occur between each pair of "|" and "=":

f x | x > 0 = 1 | otherwise = 0

This is similar to the respective mathematical notation:

$f(x) = \left\{ \begin{matrix} 1 & \mbox{if } x>0 \\ 0 & \mbox{otherwise} \end{matrix} \right.$

In this case the guards are in the "if" and "otherwise" clauses.

If there are several parallel guards, such as in the example above, they are normally tried in a top to bottom order and the branch of the first to pass is chosen. Guards in a list of cases are typically parallel.

However, in Haskell list comprehensions the guards are in series, and if any of them fails, the list element is not produced. This would be the same as combining the separate guards with logical AND, except that there can be other list comprehension clauses among the guards.

Guard (surname)

Guard is a surname. Notable people with the surname include:

  • Christopher Guard (born 1953), English actor
  • Dominic Guard (born 1956), English actor
  • Jeremy Guard (born 1970), Australian rules footballer
  • Kelly Guard (born 1983), Canadian ice hockey player
  • Philip Guard (born 1928), English actor
  • Pippa Guard (born 1952), British actress
  • Rick Guard, English singer-songwriter
Guard (grappling)

The guard is a ground grappling position in which one combatant has their back to the ground while attempting to control the other combatant using their legs. In pure grappling combat sports, the guard is considered an advantageous position, because the bottom combatant can attack with various joint locks and chokeholds, while the top combatant's priority is the transition into a more dominant position, a process known as passing the guard. In mixed martial arts competition or hand-to-hand combat in general, it is possible to effectively strike from the top in the guard, even though the bottom combatant exerts some control. There are various types of guard, with their own advantages and disadvantages.

The guard is a key part of Brazilian Jiu-Jitsu where it can be used as an offensive position. It is also used, but not formally named, in judo though it is sometimes referred to as "dō-osae" in Japanese, meaning "trunk hold". It is called the "front body scissor" in catch wrestling.

Guard (American and Canadian football)

In American and Canadian football, a guard (G) is a player who lines up between the center and the tackles on the offensive line of a football team on the line of scrimmage used primarily for blocking. Right guards (RG) is the term for the guards on the right of the offensive line, while left guards (LG) are on the left side. Guards are to the right or left of the center.

The guard's job is to protect the quarterback from the incoming defensive line and linebackers during pass plays, as well as creating openings (holes) for the running backs to head through. Guards are automatically considered ineligible receivers, so they cannot intentionally touch a forward pass, unless it is to recover a fumble or is first touched by a defender or eligible receiver.

Guard (information security)

In information security, a guard is a device or system for allowing computers on otherwise separate networks to communicate, subject to configured constraints. In many respects a guard is like a firewall and guards may have similar functionality to a gateway.

Whereas a firewall is designed to limit traffic to certain services, a guard aims to control the information exchange that the network communication is supporting at the business level. Further, unlike a firewall a guard provides assurance that it is effective in providing this control even under attack and failure conditions.

A guard will typically sit between a protected network and an external network, and ensure the protected network is safe from threats posed by the external network and from leaks of sensitive information to the external network.

A guard is usually dual-homed, though guards can connect more than two networks, and acts as a full application layer proxy, engaging in separate communications on each interface. A guard will pass only the business information carried by the protocols from one network to another, and then only if the information passes configured checks which provide the required protection.
