Deep Packet Inspection is a method of inspecting network traffic at a detailed level, analyzing the content of packets that are being transmitted across the network to detect malicious activity or violations of security policies. DPI technology became important for detecting advanced persistent threats (APTs) and identifying hidden vulnerabilities in encrypted traffic. Learn more: https://en.wikipedia.org/wiki/DPI

Kerberos is a network authentication protocol that uses ticket-based authentication to securely verify users and services in a network. Developed by MIT, it is widely used in Windows Active Directory (AD) and Unix/Linux environments. Kerberos operates on the basis of a trusted third party, known as the Key Distribution Center (KDC), which issues encrypted tickets […]

A cold site is a backup facility with basic infrastructure (power, cooling, and network connectivity) but no pre-installed hardware, software, or data. In the event of a disaster, businesses must bring in equipment and restore data before resuming operations, making it the slowest and least expensive disaster recovery option. Best for businesses that can afford […]

Disaster recovery (DR) refers to the strategies, policies, and procedures an organization implements to recover and protect its IT infrastructure, data, and applications after a disaster or significant disruption. The goal of disaster recovery is to minimize downtime, restore operations quickly, and prevent data loss in the event of natural disasters (e.g., floods, earthquakes), human […]
