Unlocking Information Security @edX by Tel Aviv University

39. Unlocking Information Security I (edX course).

The course description states the students will learn the following concepts:

        • Information Security basic terminology, vulnerabilities, exploits, and an in-depth look at a real case-study (namely, Meltdown).
        • An overview of cryptography with an emphasis on symmetric ciphers.
        • A high-level examination of hash functions and an overview of common hash algorithms.
        • A critical look at different authentication schemes, including passwords, challenge-response, and biometrics.
        • An overview of the most critical vulnerability of all times - buffer overflow, including common variants like Variable and Stack Overflow and simple yet effective mitigation techniques like canaries and DEP.

40. Unlocking Information Security II (edX course).

The course description states the students will learn the following concepts:

        • An introduction to the typical Internet protocol stack vulnerabilities, including IP Spoofing, TCP Injections, and DDoS, and useful defenses against them like NAT Boxes and Firewalls.
        • An in-depth look at the cryptographic concepts and techniques that make up the security infrastructure of the Internet: Diffie-Hellman Key Exchange, RSA Public-Key Cryptography, Digital Signatures and MAC.
        • A survey of the world wide web's security concerns (SQL Injections, CSRF, and XSS): is the Internet ultimately vulnerable or is there a silver lining?
        • An introduction to the world of malware: viruses, worms, Trojans and more - computer viruses and how to beat them.
