SEC511: Cybersecurity Engineering: Advanced Threat Detection and Monitoring

Overview

The traditional security model, focused primarily on prevention, has proven insufficient against the sophisticated and persistent threats faced by organizations today. Given the frequency and extent of significant intrusions, this should not come as a surprise.

In this section of the security engineering course, students explore the foundational concepts and methodologies that shape modern cybersecurity strategies. Beginning with a current state assessment, they review traditional and modern attack techniques, understanding how these have evolved and the implications for modern post-exploitation scenarios. The section then delves into advanced cyber defense principles, emphasizing the shift from reactive to proactive measures in continuous security monitoring, threat detection, and response. Key techniques, models, and frameworks such as MITRE ATT&CK, CIS Controls, OWASP LLM Top 10, Zero Trust, and Long Tail Analysis are introduced, providing a conceptual toolkit to better understand and mitigate threats. Students learn how to utilize frameworks to better align their defenses with known adversary tactics and techniques.

Threat-informed defensive strategies and threat hunting are central to modernized cyber defense. Learners explore how to apply MITRE ATT&CK in practical scenarios, enhancing their ability to anticipate and respond to threats.

Foundational understanding of GenAI and LLMs equips students to both leverage and defend against emerging AI technologies. Frameworks such as MITRE ATLAS and OWASP LLM Top 10 will be highlighted to structure understanding of this evolving area of cyber defense. Hands-on labs focus on detecting traditional and modern attack techniques, including practical exercises with Security Onion and Apache ActiveMQ analysis. This immersive, hands-on section is a critical component of the course's security engineer training, culminating in a NetWars Bootcamp designed to test and apply skills in real-world scenarios.

Overview

This section covers the critical aspects of security visibility and protection across cloud, edge, and network environments. It begins with an exploration of network intrusion detection and prevention systems, including malware sandboxes and honeypots, highlighting their roles in identifying and mitigating threats. The impact and importance of encryption, particularly TLS inspection and DNS query encryption, is discussed in detail, providing students with insights into balancing protection of data in transit without compromising visibility. The module also introduces various cloud protection mechanisms, such as CSPM, CIEM, CWPP, and CNAPP, alongside the MITRE ATT&CK Cloud Security Mappings, focusing on securing cloud infrastructures and services like AWS.

Edge security is another key focus, where students learn about services such as Cloud Access Security Broker (CASB), SASE, Secure Web Gateway (SWG), and Firewall-as-a-Service (FWaaS). These are vital for protecting data and applications in a modern hybrid enterprise where data, applications, and users are no longer found exclusively on-premises. This section also covers boundary protection and detection strategies, including next-generation firewalls (NGFWs) and web application firewalls (WAFs), emphasizing their role in a layered security approach. Hands-on labs provide practical experience with tools like ModSecurity, Wireshark, and intrusion detection honeypots, reinforcing the theoretical knowledge through real-world applications. The NetWars Bootcamp offers an additional immersive experience, challenging students to apply their skills in a controlled, competitive environment.

Overview

In this section, students delve into the specialized field of NDR, exploring its role within the broader context of NSM and SIEM. The content covers the essential components and tools of an NDR/NSM setup, emphasizing the importance and efficacy of various data sources, including cloud-specific considerations. These elements must be designed to provide comprehensive coverage and analytical capabilities, allowing security teams to detect and respond to threats swiftly. By leveraging advanced NDR tools and methodologies, students learn to identify and interpret suspicious activities, even within encrypted communications. Equipping students with the skills needed to identify anomalies and potential threats in network traffic requires exploration of various analytic approaches and techniques.

The focus then shifts to the hands-on practice of network threat hunting, where students learn to track implants, detect C2 traffic, and analyze both decrypted and encrypted network traffic. This section includes detailed coverage of techniques for identifying malicious traffic via beacon discovery, entropy analysis, and behavior anomaly detection, with specific reference to modern adversary tactics and tooling. The practical labs in this section include pcap payload carving and analysis with Zeek, intrusion analysis with Security Onion, and TLS anomaly detection. Hands-on labs and this sections NetWars Bootcamp provide students with the opportunity to apply these techniques and further solidify NDR skills through challenging, real-world scenarios.
