Demonstrating L7 DoS capabilities of NGINX App Protect

This repository contains the necessary files for creating NGINX App Protect DoS configuration for protection of HTTP, gRPC and Websockets.

• HTTP endpoint @ https://bank.f5labs.dev
• gRPC endpoint @ https://grpc.f5labs.dev
• Websockets endpoint @ wss://ws.f5labs.dev

Baseline and performance tests are performed with k6

To run a test:

1. start a test from one of the following baseline test files
2. on a separate host (not the same one as baseline is running from) run a test from one of the following load test files

Monitoring logs on the host where NGINX App Protect DoS is installed should show something similar to the following while under load:

[e-mail]# tail -f /var/log/adm/admd.log

ADMD.Daemon0 Feb 22 03:23:02 [info] : attack started on vs<vhost-bank.f5labs.dev>, profile<vhost-bank.f5labs.dev_prof_0>, attack_id<22>, is_under_attack=<1>, arb_declared_attack<0>, health<1.50>, global_conn<10>, L7 Drop ratio=0.00000
ADMD.Daemon0 Feb 22 03:25:26 [info] : attack ended on vs<vhost-bank.f5labs.dev> profile<vhost-bank.f5labs.dev_prof_0>, m_time_without_attack<0>

Once the baseline test is finished it should report details such as the following (showing whether traffic was affected during the load generation):

[e-mail]# k6 run k6/baseline/http-baseline-test.js

          /\      |‾‾| /‾‾/   /‾‾/

NGINX App Protect DoS Dashboard will look something like the following under a load test:

Tests can also be run with 'slow HTTP DoS' with the following commands:

[e-mail]$ slowhttptest -u https://bank.f5labs.dev

Output like the following during a 'slow HTTP DoS' will be seen in the NGINX App Protect Dashboard:
