As DevOps continue to advance, and agile development continues to be widely adopted, the latest OWASP top 10 list shows little to no movement at the top in terms of the most serious vulnerabilities affecting web applications. With a plethora of tools and information to help reduce application vulnerabilities and increase the level of security awareness in development team available, why do we still see web applications as a significant attack vector?

Champion & Analyst CHAMPION Member of project team Key contact for security Not an expert A requirement for each project ANALYST Security team member Keeps security involved Key contact for the Champion(s) Security by design thinking • Links IT Security to Development teams and projects • Encourage a community between champions and brokers • Goal to improve the overall security posture • Encourage developer collaboration with champions and analyst

- 22. Choose the right tools for the job • Before settling on what tools, ask yourself: • How frequent are your ’sprints’? • How long does each tool take to run? • Can it be wholly automated into the CI/CD process? • Is it noisy, does it generate lots of false positives? • Answering these questions will help steer you in identifying the tools appropriate for your needs 22
- 23. Perfect is the enemy of Good • Chasing perfection in a DevOps culture leads to slower development • Don’t have to fix everything during development • Compensate with other tools : IPS, WAF to mitigate unknown vulnerabilities • Focus on fixing the critical known vulnerabilities during Development • The tools you select should be agile : in both integration and scanning speed 23

- 29. DevOps • Agile success drove the need for tighter integration between Development and Operations – Coined in 2009 • Encourages (and indeed needs) collaboration between development, operations and QA – results in the need for cultural change • Allows for focus on application release automation, continuous integration and continuous delivery • Process – People – Tools approach to development • Often (and initially) leave out ‘Security teams’ Takeaways DevSecOps – culture change implemented with People | Process | Technology Process – small steps, not immediate perfection, mandate security People – establish security champions in DevOps, support the mandate Tools – integrate into the DevOps tool chain natively Shift Left – introduce additional tools and information earlier in the DevOps process
Editor's Notes
- 2001 Writing Secure Code by Howard and LeBlanc from the earlier Microsoft’s Secure Windows Initiative
- And so we end up with Agile + DevOPs being likened to that fabled Silver bullet. You know : the thing that slays the beast. In this case, addressing the need to align development to an efficient, digital pace of business today. Or the thing that magically addresses a complicated probbkem
- With the success of Agile development, in 2009 the concept of DevOps was raised by Andrew Shafer and Patrick Debois. DevOps is essentially a natural evolution of Agile, it brings closer together the Development team. The Operations team and QA to allow for the rapid release of applications through sprints. Although it requires a cultural change, organizations embracing it can develop and deliver applications much fasters Security by design is often shoe’horned into the Devops process, often focusing on the end of the development journey. however, for many years the security teams were still precluded from the process. In fact, whilst remaining a silo separate to the Agile and DevOps processes security can become the inhibitor to successfully implementing Agile and Devops cultures
- Security by design,…… Agile and DevOPs allows customers to develop and deliver applications to the market at a quck pace. And yet, time after time the surveys show that web application attacks are continually features in the top lists of incidents and often right at the top in sources of breaches.
- And OWASP constantly publish the top 10 list, not the top 3 or 5. Couple that with almost no change in top 10 over the last 4 years, its little wonder our customers are asking how, as they adopt DevOps they are constantly facing the quandary of can security fit into the DevOps model without it being a hinderance.
- Earliest form of this was Harold Leavitt’s 1964 use of 4 elements (structure, tasks, people, technology) in describing organizational change – since then, we’ve improved it to just 3 elements I like this version from Chris Penn because it clearly shows the where the benefits come from – the intersections http://www.christopherspenn.com/2018/01/transforming-people-process-and-technology-part-1/
- In 2017 Gartner shows that the biggest strategy to overcome was collaborating with Security. As organisations adopt a
- If security teams remain silo’d and disengaged from the Agile DevOps process then challenges will arise. In fact, its highly likely that Security will become a stumbling block to the success of Agile. Remember, Agile and DevOps is about collaboration (and rapid iteration). So breaking down the silo’s between the teams, integrating them together to create ‘DevSecOps’
- 1. Wrong. With the right automation and tools security can be injected into the development process much earlier. 2. Wrong, whilst they help with deployment and redeployment they simply cannot handle the security analysis that a security professional can 3. Wrong. The majority of developers are NOT security experts. Neglecting the security experts can lead to your organization becoming the next statistic on the Verizon dibr report. 4. Wrong. Keeping security as its own functional area or Silo misses the point of Agile and DevOps – namely cross-functional integration. Security Experts must partner with development and operations at the beginning of the development process. It might mean a cultural change, but it is absolutely imperative to success
- Point out – this is about situations where you have control over the DevOps process – if you outsource development, you may not be able to evolve with out external collaboration. For customization on COTS, you can still treat it as development and work towards this process Whiilst we try to move away from waterfall in the agile devops world, if we take a moment to look atboth the types of tools available and where they sit in Software development lifecycle we can identify where our own organisation is. Think about a shift left approach, if you don’t have anything inplace today, then can you fit a penetration test into the process. However, remember agile is about shorter development sprints. Therefore your pen test partner needs to be able to deliver on demand and at speed. Likewise if your doing Dast today, shifting left might mean Sast or IAST or Mast depending on the applications you are developing.

- Ultimately when considering DevSecOP and starting the journey you need to consider Voltaire’s words: Perfect is the enemy of good. Don’t chase perfection, namely the fixing of ALL vulnerabilities during the Development cycle. This will kill your ability to deliver rapid sprints as you get bogged down with testing in the old Security by design mentality. Instead, use other tools to help mitigate the unknown or less common vulnerabilities : IPS, WAF, even next gen firewalls. Have the development team focus on the known critical vulnerabiltiies and fix them, use OWASP to help guide them on how to fix and not repeat the same errors. And when selecting your SAST, DAST, Mast, IAST tools, make sure they too are agile : agile in scanning and agile in the way they integrate in the CI/CD process.
- This is what our customers are asking us for time and again. 1. in DevOps, the development team should be capable of launching and executing automated scans from directly within their native toolchain. The scanners should be easy to use and not require significant security expertise. Moreover, findings should appear in the same DevOps native toolchain.
