* Edge-Net Relay Security Test Suite
|
|
* Tests for authentication, authorization, and attack vector prevention
|
|
*
|
|
* Attack Vectors Tested:
|
|
* 1. Task completion spoofing (completing tasks not assigned to you)
|
|
* 2. Replay attacks (completing same task twice)
|
|
* 3. Credit self-reporting (clients claiming their own credits)
|
|
* 4. Public key spoofing (using someone else's key)
|
|
* 5. Rate limiting bypass
|
|
* 6. Message size attacks
|
|
* 7. Connection flooding
