Core Skills Freshers Need to Build in 2025

Let’s look at the key skills that a fresher should focus on when starting a cyber security career:

1️⃣ Networking Basics

Understanding how networks operate is crucial. You’ll need to know how data flows through systems, what protocols are in use (TCP/IP, HTTP, DNS), and where potential vulnerabilities lie.

2️⃣ Operating Systems Knowledge

Cyber security professionals often work on both Windows and Linux platforms. You’ll need to understand how operating systems function, manage permissions, and secure configurations.

Courses at institutes like Boston Institute of Analytics offer practical labs that help you master these tools.

4️⃣ Risk Management & Compliance
