Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both ...
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. The protocol is widely used in applications such as email , instant messaging , and voice over IP , but its use in securing HTTPS remains the most publicly visible.
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security, cybersecurity, digital security, or information technology security (IT security) is the protection of computer systems and networks from attacks by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware ...

The Cisco Certified Internetwork Expert (CCIE) and Cisco Certified Design Expert (CCDE) certifications were established to assist the industry in distinguishing the top echelon of internetworking experts worldwide and to ...
IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks. It supports network-level peer authentication, data origin authentication, data integrity, data confidentiality , and replay protection (protection from replay attacks).
AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. By contrast, Rijndael per se is specified with block and key sizes that may be any multiple of 32 bits, with a minimum of 128 and a maximum of 256 bits. Most AES calculations are done in a particular finite field .
Network Security Services. Network Security Services ( NSS) is a collection of cryptographic computer libraries designed to support cross-platform development of security-enabled client and server applications with optional support for hardware TLS/SSL acceleration on the server side and hardware smart cards on the client side.
