In the fields of physical security and information security, access control AC is the selective restriction of access to a place or other resource. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization. Locks and login credentials are two analogous mechanisms of access control.

Cara Kerja Software Komputer Audit' title='Cara Kerja Software Komputer Audit' />Physical access control can be achieved by a human a guard, bouncer, or receptionist, through mechanical means such as locks and keys, or through technological means such as access control systems like the mantrap. Within these environments, physical key management may also be employed as a means of further managing and monitoring access to mechanically keyed areas or access to certain small assets. Physical access control is a matter of who, where, and when. An access control system determines who is allowed to enter or exit, where they are allowed to exit or enter, and when they are allowed to enter or exit. Historically, this was partially accomplished through keys and locks. When a door is locked, only someone with a key can enter through the door, depending on how the lock is configured. Mechanical locks and keys do not allow restriction of the key holder to specific times or dates. Mechanical locks and keys do not provide records of the key used on any specific door, and the keys can be easily copied or transferred to an unauthorized person. When a mechanical key is lost or the key holder is no longer authorized to use the protected area, the locks must be re keyed. Electronic access control uses computers to solve the limitations of mechanical locks and keys. A wide range of credentials can be used to replace mechanical keys. The electronic access control system grants access based on the credential presented. When access is granted, the door is unlocked for a predetermined time and the transaction is recorded. When access is refused, the door remains locked and the attempted access is recorded. The system will also monitor the door and alarm if the door is forced open or held open too long after being unlocked. Access control system operationeditWhen a credential is presented to a reader, the reader sends the credentials information, usually a number, to a control panel, a highly reliable processor. The control panel compares the credentials number to an access control list, grants or denies the presented request, and sends a transaction log to a database. When access is denied based on the access control list, the door remains locked. If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the door. The control panel also ignores a door open signal to prevent an alarm. Often the reader provides feedback, such as a flashing red LED for an access denied and a flashing green LED for an access granted. The above description illustrates a single factor transaction. Credentials can be passed around, thus subverting the access control list. For example, Alice has access rights to the server room, but Bob does not. Alice either gives Bob her credential, or Bob takes it he now has access to the server room. To prevent this, two factor authentication can be used. In a two factor transaction, the presented credential and a second factor are needed for access to be granted another factor can be a PIN, a second credential, operator intervention, or a biometric input. There are three types factors of authenticating information 2something the user knows, e. PINsomething the user has, such as smart card or a key fobsomething the user is, such as fingerprint, verified by biometric measurement. Passwords are a common means of verifying a users identity before access is given to information systems. In addition, a fourth factor of authentication is now recognized someone you know, whereby another person who knows you can provide a human element of authentication in situations where systems have been set up to allow for such scenarios. For example, a user may have their password, but have forgotten their smart card. In such a scenario, if the user is known to designated cohorts, the cohorts may provide their smart card and password, in combination with the extant factor of the user in question, and thus provide two factors for the user with the missing credential, giving three factors overall to allow access. CredentialeditA credential is a physicaltangible object, a piece of knowledge, or a facet of a persons physical being that enables an individual access to a given physical facility or computer based information system. Typically, credentials can be something a person knows such as a number or PIN, something they have such as an access badge, something they are such as a biometric feature, or some combination of these items. This is known as multi factor authentication. The typical credential is an access card or key fob, and newer software can also turn users smartphones into access devices. There are many card technologies including magnetic stripe, bar code, Wiegand, 1. Hz proximity, 2. 6 bit card swipe, contact smart cards, and contactless smart cards. Also available are key fobs, which are more compact than ID cards, and attach to a key ring. Biometric technologies include fingerprint, facial recognition, iris recognition, retinal scan, voice, and hand geometry. The built in biometric technologies found on newer smartphones can also be used as credentials in conjunction with access software running on mobile devices. In addition to older more traditional card access technologies, newer technologies such as Near field communication NFC and Bluetooth low energy also have potential to communicate user credentials to readers for system or building access. Access control system componentsedit. Various control system components. An access control point can be a door, turnstile, parking gate, elevator, or other physical barrier, where granting access can be electronically controlled. Typically, the access point is a door. An electronic access control door can contain several elements. At its most basic, there is a stand alone electric lock. The lock is unlocked by an operator with a switch. To automate this, operator intervention is replaced by a reader. The reader could be a keypad where a code is entered, it could be a card reader, or it could be a biometric reader. Readers do not usually make an access decision, but send a card number to an access control panel that verifies the number against an access list. To monitor the door position a magnetic door switch can be used.
