Policy types

listen.dev allows for policy enforcement on network behavior.

Modes

There are 3 types of modes available

  • Observe

  • Alert

  • Action

Targets

Policy sets can be applied to targets including:

  • Network behavior: monitor network activity and allows for egress control through allowlist

  • Dependency insights: enables alerts for various types of heristics mapping to common supply chain attacks eg. unexpected outbound DNS connection, package source code accesses environment variables

  • Detection rules: these are common attack vectors (known bads) such as spawning a reverse shell (RCE), binary overwrite (tampering), read to .ssh directory (sensitive data exfiltration), etc.
