Messaging Security

  Messaging security refers to the measures taken to protect electronic communications from unauthorized access or interference. This can include measures to secure the infrastructure that supports messaging, as well as measures to secure the actual messages themselves.
  There are a number of threats to messaging security, including spam, phishing, malware, and interception of messages. To protect against these threats, organizations may use a combination of technologies, such as firewalls, antivirus software, email filters, and encryption.
  In addition to protecting against external threats, messaging security also involves protecting against internal threats, such as employees who may accidentally or intentionally expose sensitive information through messaging. This can be achieved through the use of policies and training, as well as technical controls such as data loss prevention (DLP) systems.
