The EC-Council Centre of Advanced Security Training has arrived at Firebrand Training. This three-day Cryptography Deep Dive course is an in-depth look at the field of cryptography. All modern security depends on cryptography; from using SSL to secure bank transactions, to encrypting e-commerce purchases.

You will learn about:

  • Number theory and discrete mathematics
  • Symmetric algorithms
  • Asymmetric algorithms
  • Cryptanalysis
  • Steganography
  • The history of cryptography
  • Latest and key cryptographic methods
  • Hashing and digital certificates
  • Better encryption and decryption
  • The fundamentals of L0phtCrack and Brute-force tools
  • Both manual and computerised cryptanalysis tools

Note: this course doesn't include an exam, but you'll become Cryptography Deep Dive certified.

9x Accredited Training Centre of the Year

Accredited Training Centre of the Year

Firebrand Training has again won the EC-Council Accredited Training Centre of the Year Award, from a Training Partner network that has more than 700 training centres across 107 countries. This extends a record-breaking run of successive awards to nine years.

Jay Bavisi, President of EC-Council said: “The annual EC-Council Awards highlights the commitment and achievements of our global partners and trainers that have contributed to the information security community.”

Seven reasons why you should sit your course with Firebrand Training

  1. Two options of training. Choose between residential classroom-based, or online CAST CDD courses
  2. You'll be CAST CDD certified in just 3 days. With us, you’ll be CAST CDD trained in record time
  3. Our CAST CDD course is all-inclusive. A one-off fee covers all course materials, exams, accommodation and meals. No hidden extras
  4. Pass CAST CDD first time or train again for free. This is our guarantee. We’re confident you’ll pass your course first time. But if not, come back within a year and only pay for accommodation, exams and incidental costs
  5. You’ll learn more. A day with a traditional training provider generally runs from 9am – 5pm, with a nice long break for lunch. With Firebrand Training you’ll get at least 12 hours/day quality learning time, with your instructor
  6. You’ll learn CAST CDD faster. Chances are, you’ll have a different learning style to those around you. We combine visual, auditory and tactile styles to deliver the material in a way that ensures you will learn faster and more easily
  7. You’ll be studying CAST CDD with the best. We’ve been named in Training Industry’s “Top 20 IT Training Companies of the Year” every year since 2010. As well as winning many more awards, we’ve trained and certified 105152 professionals, and we’re partners with all of the big names in the business

You should be familiar with IT security best practices, the basics of TCP/IP networking, and basic programming concepts. You should also be familiar with Metasploit and VMware.

Knowledge of programming languages isn't necessary, but it is beneficial if you have exposure to a common programming or scripting language such as Python, Perl, Ruby, C, C++, or Assembly. A programming background is not required, but you will be writing lots of code in class.

Unsure whether you meet the prerequisites? Don’t worry. Your training consultant will discuss your background with you to understand if this course is right for you.
