Building an AppSec Culture
- 1. How to develop an AppSec culture in your project Nirosh
- 2. A bit about Me I’m a Senior Security Engineer & Pentester. I have nearly three years of experience in Information Security and Secure Software Development. Educational Background • BSc. Eng (Hons) in Computer Science and Engineering - University of Moratuwa, Sri Lanka • MSc in Security Engineering (Reading) - University of Moratuwa, Sri Lanka Certifications Web application Penetration Tester (eWPT) - eLearnSecurity Certificate ID: EWPT-343 Certified Ethical Hacker (CEHv9) – EC Council Certification Number: ECC39012388466 Certified Information Security Expert (CISE) – Innobuzz License Number: 30471
- 3. Why AppSec is a major concern? From https://www.akamai.com/ (2018/08/12 – 2018/08/19)
- 4. Why web application attacks occur? Application Developers and QA Professionals Don’t Know Security “As an Application Developer, I can build great features and functions while meeting deadlines, but I don’t know how to develop my web application with security as a feature.” Steve Carter
- 5. Security Assessments What ? Why? How ?
- 6. • Periodic Assessments – Once in every quarter ( Recommended) Vulnerability Assessments • Twice a year Penetration Testing • Twice a year Security Code Reviews
- 7. Risk Classification Methodology Risks can be classified using the following methodology: Risk = Impact × Likelihood Reference: OWASP Standards
- 9. Security in Agile • Dedicated sprint focusing on application security • Stories implemented are security related • Code is reviewed Security Sprint Approach • Similar to Microsoft Security Development Lifecycle (SDL) • Consists of the requirements and stories essential to security • No software should ever be released without requirements being met Every Sprint Approach
- 10. Secure Software Development Process •Guide Developers to follow Secure Coding Guidelines •Help QAs to integrate basic security test checklist into their regular test cases •Threat Modeling and Security Designs
- 11. Threat Modeling What is it?
- 12. It is a structured approach that enables you to identify, quantify, and address the security risks associated with an application Step 4 Validate Step 3 Determine countermeasures and mitigation Step 2 Identify threats Step 1 Diagrams
- 13. An Example – User Login
- 14. Username harvesting – Show generic error message
- 15. Too user friendly. :P
- 16. Case Study: • A Norway based professional company uses a software application which can allow users to book professionals (Electrician, Plumber) and request professional services through the company. • They wanted a new feature in this application which can allow users to upload and download property documents and maintenance documents. Access to these documents must be strictly restricted to relevant users.
- 17. • Since last week, the dev team is designing the new feature for the website, that will enable authenticated users to upload and download property documents. • The architects will reuse the existing infrastructure whenever possible (they already have user accounts). • One of the board members got to know about these cyber attackers and the crazy attacks they perform which can easily damage the business and its reputation.
- 18. • He also heard about the threat modeling which helps project teams to identify major threats and take necessary security measures before they even start implementation. • He hired you to help project team with this.
- 20. What can go wrong? Microsoft’s STRIDE Model • Spoofing - Impersonate User • Tampering - Maliciously change/modify persistent data, such as persistent data in a database, and the alteration of data in transit • Repudiation - Perform an illegal action and deny it. • Information Disclosure - Read a file that one was not granted access to, or to read data in transit • Denial of Service - Deny access to valid users • Elevation of Privilege - Gain privileged access or gain unauthorized access
- 21. Threat Model
- 23. Secure Design Principles / Trust Model Authentication Authorization Cookie Management Data/Input Validation Error Handling/Information leakage Logging/Auditing Cryptography Secure Code Environment Session Management
- 26. Web Application Security Risks For 2017, the OWASP Top 10 Most Critical Web Application Security Risks are:
- 27. Tools & Technologies Vulnerability Assessment & Pentesting -OWASP ZAP, Burp suite Scanner, Acunetix, SQLMap, Kali Linux, Arachni -With lots of Manual effort- OWASP/ SANS security assessment guidelines -Third party libraries – OWASP Dependency Check, RetireJs Server-side Security Assessment Tools -Nessus, Nmap, Nikto, OpenVAS, Wireshark, Metasploit framework Static Code Analysis -Manual Code Review, Findsecbug/PMD You can use commercial tools to perform assessments if you can purchase them
- 28. Demo
- 30. Acunetix Web App Scanner
Editor's Notes
- Appsec plays a major role in the current cyber world Linkedin breach –password cracking attacks A small breach can cause huge damage to the business
- We ignore security. And we don’t consider security as a part of business requirement Secure software development life cycle. Security testing is part of that process.
- If you already built a software product, you have to establish a security assessment methodology.
- 3 popular assessment methodology for security.
- Impact – What are the consequences or damages if the vulnerability is exploited. Likelihood- how easy it is to exploit the vulnerability ( exploits available on the net)
- How you can handle these security risks?
- This can be done either beginning of the software development or at the end.
- What are the possible ways to break the system ?
- Once the basic threat agents and business impacts are understood, we should try to identify the set of controls that could prevent these threat agents from causing those impacts.
