Introductory Cyber Security
This module provides an in-depth examination of Wireless Local Area Network (WLAN) security, detailing various vulnerabilities and attack vectors that threaten the security of wireless communications. It emphasizes the weaknesses of outdated protocols like WEP and contrasts them with modern standards such as WPA2 and WPA3. Comprehensive strategies for mitigating threats such as the Evil Twin attack and the deployment of rogue access points are also discussed, equipping students with the knowledge necessary to secure wireless infrastructures effectively.
Course Chapters
Introduction and Basic Terminology
Cyber security encompasses the protection of digital assets and information systems against unauthorized access and attacks. The foundational principles are framed within the CIA Triad—Confidentiality, Integrity, and Availability—each supported by various mechanisms. A comprehensive understanding of cyber threats helps in safeguarding against potential risks, while recognizing the importance of cyber-attack surfaces reveals vulnerabilities that need to be managed. Recent significant incidents highlight the critical need for robust security measures and proactive incident response plans.
Basic Cryptography
Cryptography is essential for securing information in the digital age, encompassing both mathematical and computational methods for protecting data integrity, confidentiality, and non-repudiation. This module explores the key principles of cryptographic algorithms, including symmetric and asymmetric methods, and highlights the role of digital certificates and public key infrastructure in establishing trust. Additionally, it emphasizes the importance of robust random number generation for cryptographic security.
Authentication, Authorization, and Privilege Management
The chapter discusses the critical role of authentication and authorization in securing digital systems, emphasizing the necessity of strong authentication methods and the distinct yet complementary nature of authentication and authorization processes. It explores various access control models, including Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role-Based Access Control (RBAC), while also addressing the concept of privilege and the risks associated with privilege escalation in cybersecurity.
Application Security
Application security is a comprehensive examination of software vulnerabilities and their mitigations, including risks related to coding errors, web application vulnerabilities, and core internet protocols. The chapter covers critical topics, such as buffer overflows, XSS attacks, and secure cookie management, alongside overarching strategies for ensuring both client-side and server-side security. By understanding these vulnerabilities and implementing recommended practices, individuals can significantly improve the protection of applications against malicious exploits.
Perimeter Protection and Intrusion Detection
The module explores perimeter protection and intrusion detection, focusing on firewalls as critical network security components. It discusses various firewall architectures, such as packet-filtering and stateful inspection firewalls, as well as advanced techniques used in firewalls like next-generation firewalls (NGFWs). In addition, the importance of intrusion detection systems (IDS) and security information and event management (SIEM) systems for comprehensive security monitoring is emphasized.
Basic Malware Analysis
The module provides an extensive introduction to malware analysis, covering the classification of various malware types and their characteristics. It explores critical methodologies for analyzing malware, specifically static and dynamic analysis, alongside contemporary detection paradigms, including signature-based and behavioral detection approaches. Finally, the module prepares students with the conceptual framework necessary for understanding malware investigation processes and the strategies for neutralizing threats in a real-world cybersecurity context.
Mobile Application Security
The chapter provides an in-depth analysis of mobile application security, focusing on the attack surface, permission management, and the Android execution model. It highlights the critical importance of understanding vulnerabilities, secure design principles, and inter-process communication mechanisms in safeguarding user data. The chapter emphasizes the need to mitigate risks associated with mobile applications through robust security practices and thorough knowledge of the associated attack vectors.
WLAN Security
This module provides an in-depth examination of Wireless Local Area Network (WLAN) security, detailing various vulnerabilities and attack vectors that threaten the security of wireless communications. It emphasizes the weaknesses of outdated protocols like WEP and contrasts them with modern standards such as WPA2 and WPA3. Comprehensive strategies for mitigating threats such as the Evil Twin attack and the deployment of rogue access points are also discussed, equipping students with the knowledge necessary to secure wireless infrastructures effectively.
