This is a list of cybersecurity information technology. Cybersecurity is security as it is applied to information technology . This includes all technology that stores, manipulates, or moves data , such as computers , data networks , and all devices connected to or included in networks, such as routers and switches .
The field includes cryptographic security, transmission security, emissions security and physical security of COMSEC equipment and associated keying material. COMSEC is used to protect both classified and unclassified traffic on military communications networks, including voice, video, and data. It is used for both analog and digital ...
An important problem concerning technology assessment is the so-called Collingridge dilemma: on the one hand, impacts of new technologies cannot be easily predicted until the technology is extensively developed and widely used; on the other hand, control or change of a technology is difficult as soon as it is widely used. It emphasizes on the ...
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.
The Certified Information Systems Auditor Review Manual 2006 by ISACA provides this definition of risk management: "Risk management is the process of identifying vulnerabilities and threats to the information resources used by an organization in achieving business objectives, and deciding what countermeasures, if any, to take in reducing risk to an acceptable level, based on the value of the ...
Security was a problem. If you broadcast your plans over radio waves, anyone with a similar radio listening to the same frequency could hear your plans. Trench codes became the tactical part of World War I cryptography. Advances in electronics, particularly after World War II, allowed for electronic scrambling of voice radio.
In computer security, a threat is a potential negative action or event enabled by a vulnerability that results in an unwanted impact to a computer system or application.. A threat can be either a negative "intentional" event (i.e. hacking: an individual cracker or a criminal organization) or an "accidental" negative event (e.g. the possibility of a computer malfunctioning, or the possibility ...
Surveillance cameras can be a deterrent [16] when placed in highly visible locations and are useful for incident assessment and historical analysis. For example, if alarms are being generated and there is a camera in place, security personnel assess the situation via the camera feed.
