In the previous blog, we explored the importance of securing data at rest, focusing on encryption methods and best practices to protect sensitive information stored within PostgreSQL databases.

As we continue our journey toward comprehensive data security, we now turn our attention to securing data in transit. Ensuring that data transmitted between clients and the database server is protected against interception and tampering is equally vital.

Recently, I gave a presentation on database security, focusing on essential aspects such as users, roles, permissions, Row-Level Security (RLS), and Column-Level Security (CLS). Inspired by that experience, I thought of putting together a comprehensive blog post that deeply explores these crucial elements.

This post will provide a concise overview of how to implement a robust security model that addresses the following key elements:

Introduction to LDAP

Purpose

The Lightweight Directory Access Protocol (LDAP) is a directory service protocol that runs on a layer above the TCP/IP stack. It provides a mechanism used to connect to, search, and modify Internet directories.

How directory service works?

The LDAP directory service is based on a client-server model.

LDAP stores data in tree structure. When LDAP client connects to an LDAP server and requests information or performs an operation, the server performs the operation or provides the information.
