How does a policy-based email filtering approach function?

A policy-based email filtering approach functions by applying predefined rules to incoming and outgoing emails. This method is grounded in an organization's specific guidelines and security requirements, allowing for consistent and automated handling of emails based on established criteria.

These rules can encompass various parameters such as content keywords, attachment types, sender addresses, and recipient behaviors. By defining these policies, organizations can effectively manage and mitigate risks associated with email communications. For instance, a policy might automatically quarantine emails containing sensitive information or flagged attachments, enhancing security and helping to prevent the spread of malware within the network.

This technique allows for a systematic response to different types of threats and helps ensure compliance with regulatory standards as well as internal policies. As organizations continually refine these policies based on emerging threats or changes in business needs, the filtering approach becomes a dynamic aspect of their overall cybersecurity strategy.
