Cybersecurity attacks are inevitable for modern businesses. Therefore, it is vital that businesses deploy countermeasures to mitigate the damage these attacks cause.

This quick glossary, created by Mark W. Kaelin for TechRepublic Premium, explains the terminology behind the most common cybersecurity countermeasures.

Featured definition from the glossary:

Checksum

Refers to a numerical value that is calculated based on the contents of the data with which it is associated. If the data is altered in any way after the checksum is calculated, users should assume the data is compromised. This security protocol is used to verify sensitive data as it is transmitted or disseminated. Checksum is often systematically used in databases.
