- 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

- 16. Case Study: • ANorway 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 lastweek, 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 alsoheard 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.

Editor's Notes
- #4 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
- #5 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.
- #6 If you already built a software product, you have to establish a security assessment methodology.
- #7 3 popular assessment methodology for security.
- #8 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)
- #9 How you can handle these security risks?
- #12 This can be done either beginning of the software development or at the end.
- #13 What are the possible ways to break the system ?
- #24 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.
