Sealed Authenticator System safe at a missile launch control center with two crew locks. The two-person rule is a control mechanism designed to achieve a high level of security for especially critical material or operations. Under this rule, access and actions require the presence of two or more authorized people at all times.
A number of computer operating systems employ security features to help prevent malicious software from gaining sufficient privileges to compromise the computer system. . Operating systems lacking such features, such as DOS, Windows implementations prior to Windows NT (and its descendants), CP/M-80, and all Mac operating systems prior to Mac OS X, had only one category of user who was allowed ...
Mutual authentication is a desired characteristic in verification schemes that transmit sensitive data, in order to ensure data security. [1] [2] Mutual authentication can be accomplished with two types of credentials: usernames and passwords, and public key certificates. Mutual authentication is often employed in the Internet of Things (IoT ...
In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.
IBM Tivoli Access Manager (TAM) is an authentication and authorization solution for corporate web services, operating systems, and existing applications. [1] [2] [3] Tivoli Access Manager runs on various operating system platforms such as Unix (AIX, Solaris, HP-UX), Linux, and Windows. It has been renamed as IBM Security Access Manager (ISAM ...
In computers, logical access controls are tools and protocols used for identification, authentication, authorization, and accountability in computer information systems. Logical access is often needed for remote access of hardware and is often contrasted with the term "physical access", which refers to interactions (such as a lock and key) with ...
Pre-boot authentication can by performed by an add-on of the operating system like Linux Initial ramdisk or Microsoft's boot software of the system partition (or boot partition) or by a variety of full disk encryption (FDE) vendors that can be installed separately to the operating system. Legacy FDE systems tended to rely upon PBA as their ...
These physical security systems are known and commonly referred to as access control. Multi-factor authentication is typically deployed in access control systems through the use, firstly, of a physical possession (such as a fob, keycard, or QR-code displayed on a device) which acts as the identification credential, and secondly, a validation of ...
