But there are some terms you really should be aware of to help keep your online activity safe. Along with these new phrases, cybersecurity has joined the club of terms that can be confusing.
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.
training key - (NSA) unclassified key used for instruction and practice exercises. Type 1 key - (NSA) keys used to protect classified information. See Type 1 product. Type 2 key - (NSA) keys used to protect sensitive but unclassified (SBU) information. See Type 2 product. Vernam key - Type of key invented by Gilbert Vernam in 1918. See stream key.
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...
The following outline is provided as an overview of and topical guide to computer security: . Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data, as well as from the ...
Typically, a unique salt is randomly generated for each password. The salt and the password (or its version after key stretching) are concatenated and fed to a cryptographic hash function, and the output hash value is then stored with the salt in a database. The salt does not need to be encrypted, because knowing the salt would not help the ...
Key stretching also improves security in some real-world applications where the key length has been constrained, by mimicking a longer key length from the perspective of a brute-force attacker. [1] There are several ways to perform key stretching. One way is to apply a cryptographic hash function or a block cipher repeatedly in a loop.
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 ...
