Technical Details

what runs on :19315

KeyShadow for K2 is a suite of Software Asset Management (SAM) tools provided by Sassafras Software, incorporating components like KeyAuditor and KeyServer. This suite enables centralized control over software licensing, deployment, and usage auditing across enterprise environments. Port 19315 is used by these components to facilitate communication between client systems requesting license validation and the central KeyServer.

When a client application is launched on a user’s system, it sends a request over this port using either TCP or UDP to the KeyServer to verify license availability, lease licenses dynamically, or log audit information. This client-server communication allows real-time enforcement of licensing policies, ensuring compliance with vendor agreements and avoiding over-deployment of software.

The system supports a wide array of platforms and integrates with other IT infrastructure to enable detailed software inventory, usage analytics, and license reconciliation. By using port 19315, organizations maintain centralized control while minimizing network overhead, ensuring SAM operations are efficient and scalable.

security overview

Common Vulnerabilities:

  • Unauthorized access if the server is exposed on untrusted networks can result in license theft or tampering with audit data.
  • If communication is unencrypted, sensitive licensing or audit information can be intercepted through packet sniffing.
  • Lack of strict authentication mechanisms may allow rogue clients to impersonate legitimate clients, potentially exhausting license pools.

Mitigations:

  • Restrict access to port 19315 using firewalls or network segmentation, allowing only trusted clients and administrative IPs to connect.
  • Where possible, wrap communications within secure tunnels such as VPNs or implement application-layer encryption if the service supports it.
  • Enforce strong authentication and authorization controls for clients.
  • Keep Sassafras Software components regularly updated to patch known vulnerabilities.
  • Monitor this port for unusual activity, such as repeated failed connection attempts or unknown client signatures.
