BGPalerter: BGP prefix monitoring

  1. 1. BGPalerter Md. Zobair Khan MANRS Fellow (Training) kzobair@gmail.com Anirban Datta MANRS Ambassador (Training) engr.anirban@gmail.com
  2. 2. About BGPalerter is a self-configuring BGP prefix monitoring tool, which allows you to monitor in real-time if: • any of your prefixes loses visibility; • any of your prefixes is hijacked; • your AS is announcing RPKI invalid prefixes (e.g. not matching prefix length); • your AS is announcing prefixes not covered by a ROAs; • your AS is announcing a new prefix that was never announced before; • one of the AS path used to reach your prefix matches a specific condition defined by you. You just run it. You don't need to provide any data source or connect it to anything in your network since it connects to public repos. https://github.com/nttgin/BGPalerter
  3. 3. Composition 3 main components: connectors, monitors, and reports. Connectors retrieve/listen to the data from different sources and transform them to a common format. Monitors analyze the data flow and produce alerts. Different monitors try to detect different issues. Reports send/store the alerts, e.g. by email or to a file. Reports can also provide the data triggering such alerts. https://github.com/nttgin/BGPalerter
  4. 4. Installation Download the binary: wget https://github.com/nttgin/BGPalerter/releases/latest/download/bgpalerter-linux-x64 Download config.yml.example as config.yml (in the same directory of the binary) Make the binary executable (e.g. chmod +x bgpalerter-linux-x64) Auto-configure it: ./bgpalerter-linux-x64 generate -a _YOUR_ASN_ -o prefixes.yml -i -m Run it: ./bgpalerter-linux-x64 & to leave it running after you close the terminal https://github.com/nttgin/BGPalerter
  5. 5. Configuration For any kind of configuration, config.yml file is used. Basically nothing much to configure apart from reporting method. You can get notified by BGPalerter in case of any monitoring channel matches by various platform.

For Mail reporting: - file: reportEmail channels: - hijack - newprefix - visibility - path - misconfiguration - rpki params: showPaths: 5 # Amount of AS_PATHs to report in the alert senderEmail: zzzzzzzzz@something.net smtp: host: HOST port: 25 ignoreTLS: true auth: user: USERNAME pass: PASSWORD type: login notifiedEmails: default: - reciepiant@something.net
