I recently created a Threat Model for an application I am working on using Microsoft's Threat Modelling Tool<https://learn.microsoft.com/en-gb/azure/security/develop/threat-modeling-tool>.
It highlight two potential threats in relation to the use of the Kafka Protocol<https://kafka.apache.org/protocol> 1. Collision Attacks - Attackers who can send a series of packets or messages may be able to overlap data. For example, packet 1 may be 100 bytes starting at offset 0. Packet 2 may be 100 bytes starting at offset 25. Packet 2 will overwrite 75 bytes of packet 1. Ensure you reassemble data before filtering it, and ensure you explicitly handle these sorts of cases. 2. Replay Attacks - Packets or messages without sequence numbers or timestamps can be captured and replayed in a wide variety of ways. Implement or utilize an existing communication protocol that supports anti-replay techniques (investigate sequence numbers before timers) and strong integrity. My question is the Kafka Protocol mitigate these types of attacks and if so how?
