This in-depth analysis delves into how Cryptography has become key to modern security especially in areas using SSL for securing bank transactions, encryption for e-commerce purchases or hard drive encryption just to mention a few.
Brainstorm situations you face in your career that are unique to you alone with a highly regarded expert in this extremely technical field, at the end of the day you will be among a very elite group of specialist armed with unique skills setting you apart from other cryptanalysts.
Hacking "Secure" Encryption and Countermeasures course immerses students into the intricate science of cryptography teaching students the history of cryptography, modern cryptographic methods, and how to use techniques like cryptanalysis to break cryptography. The course also covers closely related topics such as hashing and digital certificates.
This course is appropriate for security professionals who want to understand encryption on a deeper level, and for those who may need to learn techniques in breaking encryption.
Chuck Easttom is the author of 13 computer science books including 2 computer security textbooks used at universities around the globe and translated into several languages. He also holds a host of IT certifications including MCP, MCSA, MCSE, MCAD, MCTS (Windows 7, Windows Server 2008, SQL Server 2008, and Visual Studio 2010), MCITP (Windows 7 and SQL Server 2008), MCDBA, MCT, A+, Network+, Linux+,iNet+, Server+, CEH, CHFI, ECSA, and CISSP. He currently has 7 provisional patents, all related to computer science and 4 related to computer security. One of those patents regards a new method of steganography, another regards a new approach to detecting spyware, and yet another involves the invention of a new, more stable file system.
Mr. Easttom is also the inventor of a method for quantifying network security that is being taught at several universities, and most recently has developed a new approach to creating ghost drives. He has taught various security related courses for several years and has over 10 years of teaching experience. He is also a frequent consultant on various computer related court cases including both criminal and patent cases. While Mr. Easttom has a broad range of security expertise, his passion has always been cryptography.

It is possible to circumvent or crack encryption, including hard drive encryption, depending on the way it was implemented. Cryptography is necessary in order to be able to unlock encrypted evidence.
Pen Testers/Ethical Hackers
Most penetration testers do not understand enough about cryptography to really test an organizations encryption. That means that even a thoroughly audited and pen tested organization may have major vulnerabilities in their encryption.
Selecting, implementing VPN’s or digital certificates.
Without understanding the cryptography at some depth, people are limited to following marketing hype. Understanding the actual cryptography allows you to know which one to select. A person successfully completing this course would have that knowledge.
A practical example of the benefits of cryptographic knowledge.
Hard drive encryption is a critical topic. A classic example is the use of hard drive encryption products. Windows 7 Enterprise and Ultimate come with BitLocker. This is for you to encrypt your hard drive. There are also open source products like TruCrypt that also allow you to encrypt your hard drive. Which should you use? And why? Well it so happens that Bitlocker uses AES 128 bit whereas TruCrypt uses AES 256 bit. It also happens that the U. S. National Security Agency rates the AES 256 bit for Top Secret documents whereas 128 bit AES is not rated for secret or top secret data. This course goes in detail through the AES algorithm. A student successfully completing this course would be well equipped to make this decision.
