SQL Server decoy

SQL Server is a common target in Windows networks. This decoy poses as SQL-PROD01, with the database port, the SQL Browser service and SSH.

What it emulates

Poses as: Microsoft SQL Server.

It records every connection and what each client sends. For full SQL Server emulation, which records the username and password, use the Windows file server decoy.

  • SSH 22

    Records every username, password and key fingerprint tried, then refuses them. Disconnects after six tries.

  • SQL Server 1433

    Accepts the connection and records the first bytes sent. It does not speak the protocol yet.

  • SQL Browser 1434/udp

    Records every packet that arrives. Never replies.

What it catches

Every touch, explained in plain English.

Each event gets a plain-English explanation. Related events from the same source become one incident with a recommended action.

  • Connections to the database port
  • SQL Browser queries that list instances
  • SSH password guessing
  • Port scans across the server

MITRE ATT&CK

Techniques come from a fixed table, not from AI, so the same activity always maps the same way.

  • T1046Network Service Discovery
  • T1110Brute Force

Incidents go to email, Slack, your SIEM or a signed webhook. Kandaro and your SOC

Safe by design

Built to be attacked. Never a way in.

A decoy only listens and answers with fake data. It never runs code and only connects out to Kandaro, so it can never become a way into your network.

  • It runs nothing

    The sensor has no way to run a command, load code or update itself. Every command an intruder types gets a fake text answer.

  • It connects to one place only

    Its only outbound connection is HTTPS to the Kandaro API address set at install time. Nothing Kandaro sends can change that address.

  • Kandaro can only send it settings

    Which decoy to imitate, which services to turn off, which addresses to ignore. There is no field for code, files, commands or updates.

  • It holds no real secrets

    Passwords, keys and records it shows are fake. Its only credential is its own key, which can send events for your organisation and nothing more.

  • It cannot be used to attack others

    It never forwards traffic, never fetches a URL and never serves scripts or programs. Its only UDP replies (SNMP) are rate-limited per address.

Where to put it

Place it where an intruder will look.

Put it in the database network, next to your real SQL Servers.

Installs in about a minute with Docker, Kubernetes, Ansible, a VM or a Raspberry Pi, and needs outbound HTTPS only. Deployment guide · Where to put your first decoys

FAQ

SQL Server decoy questions

Does it hold any data?
No. It accepts connections and records what clients send, nothing more.
Is it safe to run on my network?
Yes. A decoy only answers connections with fake data. It runs nothing, forwards nothing and only connects out to the Kandaro API over HTTPS. It runs as an unprivileged, read-only container.
