communication security的意思|示意

Communication security, also known as cyber security or information security, is the protection of data sent and received by digital channels, such as phone lines, radio waves and the Internet. It is used to protect data from being stolen, manipulated or otherwise misused by unauthorised parties.

Communication security works by encrypting data sent and received. Encryption scrambles the data so that only authorised users can decode it. This prevents third parties from understanding the data and using it for malicious purposes. For example, communication security can be used to protect financial transactions sent over the internet and to protect sensitive emails from being accessed without permission.

Communication security can also involve authentication protocols, which verify that the sender and receiver of data are authorised to do so. This makes sure that only authorised users can access the data, as well as ensuring that the data sent is exactly what was intended.

Communication security is an important part of any business's security protocol. It ensures that critical data is protected from unauthorised access and misuse. It is important to keep communication security up to date to protect against new threats, as the technology used can become outdated quickly.
