Cyber Attack Countermeasures (Coursera)

Offered by New York University,
Cyber Attack Countermeasures (Coursera)

This course introduces the basics of cyber defense starting with foundational models such as Bell-LaPadula and information flow frameworks. These underlying policy enforcements mechanisms help introduce basic functional protections, starting with authentication methods. Learners will be introduced to a series of different authentication solutions and protocols, including RSA SecureID and Kerberos, in the context of a canonical schema.

The basics of cryptography are also introduced with attention to conventional block ciphers as well as public key cryptography. Important cryptographic techniques such as cipher block chaining and triple-DES are explained. Modern certification authority-based cryptographic support is also discussed and shown to provide basis for secure e-commerce using Secure Sockets Layer (SSL) schemes.

Deception As a Defense (Coursera)

In this course, defensive concepts will be explored and the power of using deception at different layers of the network. The attacker depends on information that is gathered during their surveillance, and with deception we change the network at layer 2-4 and the result of this is the attacker’s collected data is no longer valid and useless for them, this requires the attacker to start the information gathering process over again.

International Cyber Conflicts (Coursera)

By nature, cyber conflicts are an international issue that span across nation-state borders. By the end of the course, you will be able to apply the knowledge gained for analysis and management of international cyber incidents and conflicts including for activities such as development of policy related to cybercrime and cyberwarfare. Management of cyber incidents and conflicts requires an interdisciplinary perspective including an understanding of: 1) characteristics of the cyber threats and conflicts themselves, 2) international efforts to reduce and improve cyber security, and 3) psychological and sociopolitical factors.
