What are countermeasures? Why is it important for organizations to implementcountermeasures?
What will be an ideal response?
Countermeasures are software or procedures used to prevent an attack. They make data
breaches improbable, or unlikely to occur. Phishing detection software, user authentication
systems, network intrusion detection systems, and data loss prevention systems are examples of
countermeasures that can be taken by organizations. A network intrusion detection system
(NIDS) used to examine traffic passing through an organization's internal network can identify
possible attacks. Finally, data loss prevention systems (DLP), which are designed to prevent
sensitive data from being released to unauthorized persons, can be used to stop the data from
leaving the internal network. Such countermeasures help to detect and stop hacker activity at
each step of data breaching.
