The invention discloses a mail security control method and system, and relates to the technical field of network security. A specific implementation of the method includes: in response to receiving the port mirroring traffic, parsing the port mirroring traffic; sending the parsing result to the email security gateway; processing the parsing result through the email security gateway, The destination IP address and destination port in the group information are adjusted to the local loopback virtual IP address and local port; according to the local loopback virtual IP address and local port included in the adjusted quintuple information, the processing result of the email security gateway is returned to the local Transparent proxy application; based on the processing results received by the local transparent proxy application, control the email security gateway, and monitor the security of emails through the serial mode of the email security gateway. This implementation enables the Email Security Gateway to juggle serial mode and bypass mode.
Description
technical field [0001] The invention relates to the technical field of network security, and in particular, to a method and system for email security control. Background technique [0002] At present, mail security is mainly achieved through mail gateways. Among them, the implementation of the mail gateway can have bypass mode and serial mode. Among them, the bypass mode means that the mail gateway obtains the mirror traffic of the mail, and judges whether the mail is safe by analyzing the mirror traffic; the serial mode means that the mail gateway intercepts the mail, parses the mail, and compares the analysis result with the preset black List or whitelist, etc. to match, according to the matching results, to determine whether the mail is safe. [0003] Due to the different internal working methods of the email security gateway in serial mode and bypass mode, the email security gateway cannot take into account the serial mode and bypass mode.
