Network Security Course Curriculum & Syllabus at Techcadd

Before diving into complex security protocols, students must build a rock-solid understanding of how networks operate. This foundational module covers the essential concepts of network architecture, including the OSI model, TCP/IP stack, and various network topologies. You will learn how data packets travel across networks, the function of different hardware components like routers and switches, and how to configure IP addresses, subnets, and routing protocols effectively.

Furthermore, this module introduces students to network services such as DNS, DHCP, and HTTP/HTTPS. Understanding these core services is critical, as they are often the primary targets for cyberattacks. By the end of this module, you will have the practical skills to set up a basic network environment and troubleshoot common connectivity issues, laying a strong foundation for the advanced security topics that follow.

This module transitions into the core principles of cybersecurity, introducing students to the CIA Triad—Confidentiality, Integrity, and Availability. You will explore the current threat landscape, understanding the motivations and methodologies of different types of hackers, including black hat, white hat, and gray hat. The curriculum covers various forms of malware, such as viruses, worms, trojans, and ransomware, and how they infiltrate systems.

Additionally, students will learn about social engineering tactics, phishing attacks, and insider threats. The module emphasizes the importance of security policies, risk management, and compliance standards. By analyzing real-world case studies of major data breaches, learners will understand the devastating impact of poor security practices and the critical role of a proactive defense strategy in modern organizations.

In this hands-on module, students step into the shoes of an ethical hacker to understand how vulnerabilities are discovered and exploited. You will learn the phases of ethical hacking, including reconnaissance, scanning, gaining access, maintaining access, and covering tracks. The course provides extensive training on using industry-standard tools like Nmap, Wireshark, and Metasploit to perform network scanning and vulnerability assessments.

Students will also delve into web application security, learning about the OWASP Top 10 vulnerabilities, such as SQL injection, Cross-Site Scripting (XSS), and broken authentication. Through practical lab exercises, you will learn how to safely exploit these vulnerabilities in a controlled environment and, more importantly, how to recommend and implement effective remediation strategies to secure the systems.

Building on the offensive skills learned previously, this module focuses on defensive strategies and security architecture. Students will learn how to configure and manage firewalls, Intrusion Detection Systems (IDS), and Intrusion Prevention Systems (IPS) to protect network perimeters. The curriculum also covers Virtual Private Networks (VPNs), secure remote access, and the implementation of Network Access Control (NAC) policies.

A significant portion of this module is dedicated to cryptography, covering symmetric and asymmetric encryption, hashing algorithms, and Public Key Infrastructure (PKI). You will learn how encryption is used to secure data in transit and at rest, and how to implement SSL/TLS certificates. By the end of this module, students will be capable of designing a robust, multi-layered defense strategy for any organization.
