Type: Technical Publication / Academic Research Report
Length: 26 pages
Abstract:
Communication networks are the foundation of modern society; they allow the secure exchange of information across organizations, governments, and defense systems. But these networks face increasing risks from cyberattacks that exploit both technical flaws and human error. This report analyzes six major attack types: ransomware, zero-day exploits, phishing and spear phishing, SQL injection, DNS spoofing, and man-in-the-middle (MITM), and the related defenses designed to protect communication networks. Each section defines the attack, explains how it works, highlights real-world examples, and describes defense techniques such as patch management, network segmentation, encryption, multi-factor authentication, and user awareness training. The report shows how these attacks threaten data integrity, confidentiality, and availability within the Department of Defense (DoD) and other critical infrastructure networks. Overall, the report demonstrates that layered security combining technical controls, user education, and continuous monitoring is essential to maintaining reliable communication networks and national cybersecurity resilience.
Skills Demonstrated:

Executive Summary:
This publication provides a detailed analysis of six major cyberattacks targeting communication networks, ransomware, zero-day exploits, phishing, SQL injection, DNS spoofing, and MITM. It includes attack flow diagrams, real-world case studies, and defense strategies. Visuals from pages 7, 10, 12, 18, 19, and 22 illustrate how attackers breach communication networks and how layered defense mechanisms stop them. The report highlights the importance of segmentation, encryption, patching, monitoring, and user training in defending national-security systems and critical-infrastructure networks.
