Claim:
1. A computer-implemented method, comprising: selecting a second computer system for testing from a plurality of computer systems in a distributed system; obtaining a message addressed from a first computer system to the second computer system, the message comprising cryptographic information and being part of a handshake process for establishing a secure communications channel, the handshake process being part of a protocol that specifies a particular response as a result of the cryptographic information being invalid; modifying the cryptographic information of the message obtained to cause the cryptographic information to become invalid, thereby resulting in a modified message; transmitting the modified message to the second computer system; determining, as a testing result, that the second computer system, after receiving the modified message, failed to implement the particular response; and on a condition that the testing result indicates that the second computer failed to implement the particular response, performing one or more mitigating operations.
