Welcome to Mikrocata2SELKS 👋

📋 Introduction

This repository is designed to simplify the installation process for the IDS/IPS Suricata for packet analysis from Mikrotik devices.

Minimum Requirements:

• 4 CPU cores
• 10 GB of free RAM
• Minimum 10 GB of free disk space (actual disk occupation will mainly depend of the number of rules and the amount of traffic on the network - 200GB+ SSD grade recommended).

🚀 Install

• Setup a fresh Debian 12 install on a dedicated machine (server or vm)
• Login as root
• Install git with 'apt install git'
• Clone this git repo 'git clone https://github.com/angolo40/mikrocata2selks.git'
• Edit easyinstall.sh with path where to install SELKS and how many Mikrotik to handle
• Run ./easyinstall.sh
• Once finished edit /usr/local/bin/mikrocataTZSP0.py with your Mikrotik and Telegram parameters and then reload service with 'systemctl restart mikrocataTZSP0.service'
• Configure Mikrotik

📡 Mikrotik Setup

• /tool sniffer set filter-stream=yes streaming-enabled=yes streaming-server=[DEBIANIP]:37008 (37008 is default port for Mikrotik0)
• /tool sniffer start
• /ip/firewall/raw/add action=drop chain=prerouting comment="IPS-drop_in_bad_traffic" src-address-list=Suricata
• /ip/firewall/raw/add action=drop chain=prerouting comment="IPS-drop_out_bad_traffic" dst-address-list=Suricata Enabling Mikrotik API:
• /ip service set api-ssl address=[DEBIANIP] enabled=yes Add Mikrocata user in Mikrotik:
• /user/add name=mikrocata2selks password=xxxxxxxxxxxxx group=full (change password)

🛠️ Handle Multiple Mikrotik Devices

• Setting more than 1 Mikrotik it will create for each device a dedicated dummy interface and dedicated mikrocata service.
• Example:
• • for Mikrotik0 will create tzsp0 interface listening at 37008 port and /usr/local/bin/mikrocataTZSP0.py
• • for Mikrotik1 will create tzsp1 interface listening at 37009 port and /usr/local/bin/mikrocataTZSP1.py
• • for Mikrotik2 will create tzsp2 interface listening at 37010 port and /usr/local/bin/mikrocataTZSP2.py
• • and so on...
• • So you have to edit:
• • /usr/local/bin/mikrocataTZSP0.py with specific Mikrotik0 value and enable sniffer on Mikrotik0 sending data to 37008 port.
• • /usr/local/bin/mikrocataTZSP1.py with specific Mikrotik1 value and enable sniffer on Mikrotik1 sending data to 37009 port
• • /usr/local/bin/mikrocataTZSP2.py with specific Mikrotik2 value and enable sniffer on Mikrotik2 sending data to 37010 port.
• • and so on...
