Network security covers a variety of computer networks, both public and private, that are used in everyday jobs: conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.
The security of the system depends on the secrecy of the private key, which must not become known to any other. Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key.
A virtual private network (VPN) is one of the most important ways to protect personal information. A VPN connects a private network to a public network, which helps users share information through public networks by extending them to their computer devices. Thus, VPNs users may benefit from more security. [11]
A public key infrastructure (PKI) is a system for the creation, storage, and distribution of digital certificates which are used to verify that a particular public key belongs to a certain entity. The PKI creates digital certificates which map public keys to entities, securely stores these certificates in a central repository and revokes them ...
A key aspect of privacy in blockchains is the use of private and public keys. Blockchain systems use asymmetric cryptography to secure transactions between users. [7] In these systems, each user has a public and private key. [7] These keys are random strings of numbers and are cryptographically related. [7]
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 ...
Soft privacy technologies are used where it can be assumed that a third-party can be trusted for the processing of data. This model is based on compliance, consent, control and auditing. [2] Example technologies are access control, differential privacy, and tunnel encryption (SSL/TLS).
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.
