8,497 recent views

This course builds upon the skills and coding practices learned in both Principles of Secure Coding and Identifying Security Vulnerabilities, courses one and two, in this specialization.  This course uses the focusing technique that asks you to think about:  “what to watch out for” and “where to look” to evaluate and ultimately remediate fragile C++ library code. 
The techniques you’ll be examining will make your programs perform accurately and be resistant to attempts to perform inaccurately. This is really what the term secure programming means. You will be shown common errors that people make, and then learn how to program more robustly. You will apply tips and best practices to help you improve your programming style and help you to avoid common problems like buffer overflows, which may or may not cause security problems.

What you will learn

Apply “what to watch out for” and “where to look” to evaluate fragility of C++ library code.
Given a fragile C++ library, code a robust version.
Identify problems w/ privilege, trusted environments, input validation, files & sub-processes, resource mngmt, asynchronicity, & randomness in C/C++.
Remediate examples of problems that apply to C/C++ interactions with the programming environment.

Users, Privileges, and Environment Variables

In this module, you will be able to manage users and privileges when you run programs or sub-programs. You will be able to identify and use the different types of privileges on a Linux (and UNIX-like) system. You'll be able to identify how program shells preserve environment settings. You will be able to examine how your shell (or other program that uses the PATH variable) deals with multiple versions of that variable.

Validation and Verification, Buffer and Numeric Overflows, and Input Injections

In this module, you will be able to breakdown how the process of checking inputs, known as validation and verification works. You will be able to avoid and buffer numeric overflows in your programs. You will be able to discover what happens when you call functions with parameters that cause overflows. And finally, you will be able to detect various input injections such as cross-site scripting and SQL injections and be able to describe the consequences of not examining input.

Randomness, Cryptography, and Other Topics

In this module you will be able to distinguish between pseudo-randomness and actual randomness. You will be able to apply randomness in the coding environment and generate random numbers and look at their distribution. You'll be able to identify and describe how and why cryptography is used, as well as why you should use trusted cryptography code libraries instead of crafting your own solution. You will be able to analyze and consider best practices for handling sensitive information, passwords, crypto keys, how to handle errors in security sensitive programs, and how to defend against string attacks. You will be able to hash a password and then try to guess another one. You will be able to practice cleaning out environments to make them safe for untrusted subprocesses, as well as practice handling integer overflow.

TOP REVIEWS FROM IDENTIFYING SECURITY VULNERABILITIES IN C/C++PROGRAMMING

by RKMay 12, 2020

Practical demos could have added more fun to this course.

by VPNov 30, 2020

More code and Example would be good in this code, Example code for Discussion would be good for ideal reference

by BDJun 12, 2020

This was interesting: a good introduction on what we need to develop a secure program and most common sources of vulnerabilities. Thank you!

by HHMay 30, 2020

Thoroughly enjoyed the course. learned a lot. thank you.

About the Secure Coding Practices Specialization

This Specialization is intended for software developers of any level who are not yet fluent with secure coding and programming techniques.Through four courses, you will cover the principles of secure coding, concepts of threat modeling and cryptography and exploit vulnerabilities in both C/C++ and Java languages, which will prepare you to think like a hacker and protect your organizations information. The courses provide ample practice activities including exploiting WebGoat, an OWASP project designed to teach penetration testing.

Frequently Asked Questions

When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
