In computer networking, a reliable protocol is a communication protocol that notifies the sender whether or not the delivery of data to intended recipients was successful. Reliability is a synonym for assurance , which is the term used by the ITU and ATM Forum , and leads to fault-tolerant messaging .
The Recovery Time Objective (RTO) [9] [10] is the targeted duration of time and a service level within which a business process must be restored after a disruption in order to avoid a break in business continuity.
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 ...
The physical security of a data center is the set of protocol built-in within the data center facilities in order to prevent any physical damage to the machines storing the data. Those protocols should be able to handle everything ranging from natural disasters to corporate espionage to terrorist attacks.
An exploit is the delivery mechanism that takes advantage of the vulnerability to penetrate the target's systems, for such purposes as disrupting operations, installing malware, or exfiltrating data. [6] Researchers Lillian Ablon and Andy Bogart write that "little is known about the true extent, use, benefit, and harm of zero-day exploits". [7]
Information security is the practice of protecting information by mitigating information risks. It is part of information risk management. [1] It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information.
An example of a data-integrity mechanism is the parent-and-child relationship of related records. If a parent record owns one or more related child records all of the referential integrity processes are handled by the database itself, which automatically ensures the accuracy and integrity of the data so that no child record can exist without a parent (also called being orphaned) and that no ...
The standard requires effective security measures that protect sensitive (personal) data and other assets, such as command and control data. It also requires that security vulnerabilities in the software have been eliminated, security principles, such as defense-in-depth have been followed, and the security of the software has been verified ...
