  • Wrap up

What you will learn

  • Getting familiar with essential cyber security concepts
  • Understanding how cryptography supports security
  • Learning how to use cryptographic APIs correctly in Java
  • Understanding Web application security issues
  • Detailed analysis of the OWASP Top Ten elements
  • Putting Web application security in the context of Java
  • Going beyond the low hanging fruits
  • Managing vulnerabilities in third party components

Description

Your Web application written in Java works as intended, so you are done, right? But did you consider feeding in incorrect values? 16Gbs of data? A null? An apostrophe? Negative numbers, or specifically -1 or -2^31? Because that’s what the bad guys will do – and the list is far from complete.

Handling security needs a healthy level of paranoia, and this is what this course provides: a strong emotional engagement by lots of hands-on labs and stories from real life, all to substantially improve code hygiene. Mistakes, consequences, and best practices are our blood, sweat and tears.

The curriculum goes through the common Web application security issues following the OWASP Top Ten but goes far beyond it both in coverage and the details.All this is put in the context of Java, and extended by core programming issues, discussing security pitfalls of the Java language and the runtime environment.

So that you are prepared for the forces of the dark side.

So that nothing unexpected happens.

Nothing.

I didn't expect this coming

I have been coding for 15 years and never thought I would still come across such important security cornerstones.
