Connect Akto with F5

F5 is a leading application security and delivery platform that provides advanced traffic management and security features. Integrating F5 with Akto allows automatic discovery and security testing of all APIs flowing through your F5 infrastructure, ensuring comprehensive security coverage across your application delivery network.

Prerequisites

1. Go to app.akto.io. Login/Signup into your account.
2. Click on Quick Start tab in left nav

3. Search for Hybrid SaaS Connector and click connect

4. Copy the token as specified under Runtime Service Command heading. This will be later used in setting up Akto Traffic Processor

Setting Up Akto Traffic Collector

1. Create a new instance

2. Login into the instance and save the following file as docker-compose-traffic-collector.yml

1. Replace ${AKTO_KAFKA_IP} in the above file with your instance’s ip

2. Save below snipped as docker-akto-collector.env. Replace <traffic_processor_instance_ip> with your instance ip.

AKTO_TRAFFIC_BATCH_TIME_SECS=10
AKTO_TRAFFIC_BATCH_SIZE=100
AKTO_KAFKA_BROKER_MAL=<traffic_processor_instance_ip>:9092
AKTO_BYTES_IN_THRESHOLD=10

1. Run docker-compose -f docker-compose-traffic-collector.yml up -d

2. Expose UDP port 1053 on this instance

Traffic Processor Setup

1. Login into the Traffic Collector Instance

2. Save the following file as docker-compose-runtime.yml

version: '2.1'

services:
  akto-api-security-runtime:
    image: public.ecr.aws/aktosecurity/akto-api-security-mini-runtime:latest
    env_file: ./docker-mini-runtime.env
    mem_limit: 8g
    restart: always

1. Save the following file as docker-mini-runtime.env. Replace with token value copied in Prerequisites step. Replace <traffic_processor_instance_ip> with your instance ip.

AKTO_CONFIG_NAME=staging
AKTO_KAFKA_TOPIC_NAME=akto.api.logs

    set response_payload ""
    if { [HTTP::payload length] > 0 } {

    }
}

1. Attach the iRule to your virtual server by going to resources section under your virtual server.
