The process of automatically sorting and managing incoming email messages based on predefined criteria.
Description
Email filtering is a crucial cybersecurity practice that helps organizations manage and protect their email communications from threats such as spam, phishing attacks, and malware. By implementing email filtering systems, businesses can automatically identify and segregate unwanted or harmful emails from legitimate correspondence. These systems use various techniques, including keyword analysis, sender reputation, and machine learning algorithms, to assess the risk level of each incoming message. For instance, a company might use email filters to block emails containing suspicious links or attachments, thus reducing the likelihood of a successful cyber attack. Additionally, email filtering can enhance productivity by ensuring that employees are not overwhelmed with spam and irrelevant messages. Organizations often adjust their filtering criteria based on evolving threats and business needs, making it a dynamic aspect of their cybersecurity strategy.
Examples
- Spam filters that block unsolicited promotional emails, like those from companies offering free trials.
- Phishing detection systems that flag emails pretending to be from well-known banks asking for sensitive information.
Additional Information
- Many email service providers, like Gmail and Outlook, have built-in email filtering capabilities to enhance user security.
- Regular updates and training on email security can help employees recognize phishing attempts that may bypass filters.
