Abstract
Separating awareness of multipart file transmissions of different applications from traffic handling at a granularity of an individual application layer session facilitates efficient cybersecurity enforcement on multipart file transmissions. A protocol-based multipart file transmission regulator (“regulator”) determines a per session message handling action to prevent completion of a multipart file transmission based on a protocol of an application identified for the session until cybersecurity analysis can be performed. The regulator then communicates the message handling action to a network component supporting the session. The regulator maintains information and file chunks in a data store for active sessions and determines with the data store whether a condition for requesting cybersecurity analysis for a multipart file transmission is satisfied. Upon obtaining a cybersecurity analysis verdict, the regulator provides the verdict or a verdict based instruction to the network component that ensures the multipart file transmission is compliant with a cybersecurity policy(ies).
