# Server Message Block

## What is Server Message Block?

The Server Message Block (SMB) protocol is a client-server communication protocol that enables shared access to files, directories, printers, serial ports, and other resources on a network. It also provides an authenticated inter-process communication (IPC) mechanism.

## Why Should You Use the Server Message Block Connector?

The Server Message Block connector provides visibility into the assets in your environment. You can use this visibility to:

- ensure assets are managed per your security policies
- derive relationships between assets, users, applications, and data

## How Does This Connector Work?

Lucidum executes read-only requests to the Server Message Block REST API and ingests only meta-data about Server Message Block devices. Lucidum does not retrieve any data stored on your assets.
