If you’re looking to deepen your understanding of information security, the course ‘Segurança de TI: defesa contra as artes negras digitais’ on Coursera is an excellent choice. Designed to provide both foundational knowledge and advanced practices, this course covers a wide array of critical topics in cybersecurity. From understanding common threats and malware to diving into cryptography, network security, and building a security-aware organizational culture, it offers a holistic approach to cybersecurity.
The course is structured into detailed weekly modules, making complex concepts accessible. In the initial weeks, you will learn about the threats faced in the digital landscape, including malware, network attacks, and security principles such as the CIA triad. As you progress, you’ll explore cryptography — understanding the differences between symmetric and asymmetric encryption, hashing, and how to select suitable cryptographic methods.
Subsequent modules focus on AAA security principles (Authentication, Authorization, and Auditing), network architecture security, and advanced defensive strategies like system hardening, firewalls, encryption, and patch management. The course culminates in teaching how to foster a security-conscious culture within an organization, equipping you with the skills to create effective security policies and plans.
What makes this course particularly valuable is its practical orientation. The inclusion of tools like tcpdump for network analysis and guidance on configuring security measures ensures you’re not just learning theory but also acquiring hands-on skills applicable in real-world scenarios.
I highly recommend this course for IT professionals, cybersecurity enthusiasts, or anyone interested in understanding how to defend digital assets effectively. It provides a comprehensive, well-structured curriculum that balances theory with practical skills — essential in today’s increasingly digital and threat-prone environment.
