Hello everyone. im trying to Send/Receive messages between Server and Clients. for the moment im simply sending my buffers as byte's but It’s a massive security risk to take data coming in over the network and trust it. that’s exactly what im doing when i just copy a block of memory into a struct and if somebody constructs a malicious Packet (Tn) and sends it the Server will Crash for sure . i know i can do some sort of per-field checking that values are in range but this is not a good approach for performance. any suggestions will be much appreciated !!
