What You Will Learn
System Security
1 month to completeExplore the basics of system security and its implementation at the operating system level. Learn about implementing authentication and authorization as a means to protect access to data and services. Learn about detecting unauthorized changes to a system and how to effectively counter them. By the end, you’ll understand how to build logging, monitoring, and auditing tools that can alert system security breaches and how to effectively counter them in a real-world case.
Prerequisite knowledge
Basic familiarity with Cybersecurity topics
Identifying Vulnerabilities
Explore the operating system’s security model and understand CVEs and third party advisory reports. Detect vulnerabilities in software and third-party libraries and patch identified vulnerabilities
Authentication
Explore Unix password storage management and its security features. Defend remote service authentication mechanisms and server hardening principles and implement encryption for data at rest and in motion.
Authorization
Understand access controls and their implementation as a means for securing data. Explore ways to detect unauthorized services and processes and how to remediate them. Use networking features to prevent unauthorized access to the system or server.
Isolation
Learn how to implement a chroot jail to enhance system security. Understand mandatory access control and how it differs from discretionary access control. Understand advanced attacks like buffer overflows.
Auditing
Implement auditing controls on critical files and services and host-based intrusion detection. Implement file integrity monitoring through osquery. Detect the presence of malware through system scans and write YARA rules for advanced threat hunting.
Course Project: Responding to a Nation-State Cyber Attack
In this project, you will implement the course learnings to investigate a Linux virtual image that was taken from the server and was compromised in the cyber espionage campaign carried out by North Udan. You will work towards identifying the infection chain along with assessing and improving the system’s resilience against malicious attacks by building scanning, monitoring, and auditing tools.
