FortiGate is a comprehensive network security platform that provides firewall, VPN, intrusion prevention, and other security features. One of its key features is the ability to perform an email checksum check, which helps to enhance email security. In this article, we will explore what email checksum is, how it works, and how FortiGate can help businesses improve their email security by performing an email checksum check.
What is Email Checksum?
A checksum is a value that is calculated from a block of digital data to verify its integrity. In the context of email, a checksum is used to ensure that the email has not been altered during transit. When an email is sent, a checksum is calculated based on the content of the email. When the email is received, the recipient’s email client recalculates the checksum and compares it to the original checksum. If the two values match, the email has not been tampered with during transit.
How Email Checksum Works
Email checksum works by creating a hash value of the email content, which is a unique digital fingerprint of the email. This hash value is calculated using a cryptographic algorithm, such as MD5 or SHA-1. The hash value is then inserted into the email header as a checksum.
When the email is received, the recipient’s email client calculates the checksum value based on the email content and compares it to the checksum value in the email header. If the two values match, the email has not been tampered with during transit.
How FortiGate Performs Email Checksum Check
FortiGate is a network security platform that provides a wide range of security features, including the ability to perform an email checksum check. When an email is sent through FortiGate, it calculates the email checksum and inserts it into the email header. When the email is received, FortiGate recalculates the checksum value based on the email content and compares it to the checksum value in the email header. If the two values match, the email is considered to be valid and has not been tampered with during transit. If the two values do not match, the email is considered to be invalid and may be blocked or quarantined.
