Information
The IDPS must include protection against DoS attacks that originate from inside the enclave which can affect either internal or external systems. These attacks may use legitimate or rogue endpoints from inside the enclave.
To perform signature-based attacks on the Juniper SRX IDPS device, create a signature-based attack object.
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Solution
Specify a name for the attack. Specify common properties for the attack. Specify the attack type and context. Specify the attack direction and the shellcode flag. Set the protocol and its fields. Specify the protocol binding and ports. Specify the direction.
