Threat Stack Playbooks - Part 3

Self-Protecting Cloud - Part 3

Setup Python Bot

The following series of commands are intended to configure the python bot to communicate with the Threat Stack API. The python bot can be found in the home directory of the Linux host.

Step 1: Download & Unzip Python-Bot

Step 2: Update Threat Stack Credentials File

Launch Python Bot

Use the RuleID provided below to detect network outbound connection to WAN and then auto add the CIDR block to the AWS NACL ID. The AWS VPC will block the added CIDR Block in near-realtime.

• RuleID: 448889bf-eb81-11ec-b41e-1734e5d9feb0
• ACL ID: acl-06ead5a200e17b7d4

Be aware that the RuleID below is a VALID and can be found in F5 - Agility Labs > Rules > Base Rule Set > Network: Outbound Connection (Connects) to WAN.

Warning

In UDF, Linux instance python bot may require pip3 install boto3 or pip3 install –upgrade awscli

The python bot will now watch for the RuleID to be triggered. Leave terminal connected, and **start a new terminal session*.

Results

New Terminal

In a new terminal we will sample activity from the python bot observing the rule. Once the rule triggers, the python bot grabs the destination/source IPs from the alert (and any contributing event) to then add them to the AWS VPC ACL using the AWS CLI.
