Header checking

What is meant by Header checking?

The term "header verification" refers to the process of analyzing and validating header data in an email or other data packets to ensure its authenticity and integrity. The header contains important information such as sender, recipient, subject, and timestamp, which is used to identify and classify the message. Header verification is crucial for detecting and preventing phishing attacks, spam, and other security risks.

Typical software functions in the area of "header verification":

1. Header Data Analysis: Detailed examination of header information to verify the origin and path of the message.
2. Authentication: Validation of the authenticity of header information to ensure that the message comes from a legitimate sender.
3. Tampering Detection: Detection and reporting of alterations or manipulations in the header data that might occur during transmission.
4. Email Domain Validation: Verification of the match between the sender’s domain and the domains specified in the headers.
5. Logging and Reporting: Documentation and analysis of the results of header verification, including the creation of reports on suspicious or erroneous headers.
6. Integration of Security Protocols: Support for protocols such as SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to verify header authenticity.
7. Error Notification: Automated notifications and alerts for faulty or suspicious header data.
