TO enhance their approaches to cyber and other risks, forward-thinking organisations are embedding security, privacy, policy, and controls into their DevOps culture, processes, and tools. As the DevSecOps trend gains momentum, more companies will likely make threat modelling, risk assessment, and security-task automation foundational components of product development initiatives, from ideation to iteration to launch to operations. DevSecOps fundamentally transforms cyber and risk management from being compliance-based activities—typically undertaken late in the development life cycle—into essential framing mindsets across the product journey. Moreover, DevSecOps codifies policies and best practises into tools and underlying platforms, enabling security to become a shared responsibility of the entire IT organisation.
DevOps tactics and tools are dramatically changing the way IT organisations innovate. And in the midst of this transformation, IT leaders are finding that longstanding approaches for integrating security into new products are not keeping pace with high-velocity, continuous delivery software development. Indeed, in the DevOps arena, traditional “bolt-on” security techniques and manual controls that are reliant on legacy practises are often perceived as impediments to speed, transparency, and overall security effectiveness.
In a growing trend, some companies have begun embedding security culture, practises, and tools into each phase of their DevOps pipelines, an approach known as DevSecOps. Deployed strategically, DevSecOps can help improve the security and compliance maturity levels of a company’s DevOps pipeline, while boosting quality and productivity and shrinking time-to-market. How? Automation tools execute tasks uniformly and consistently, whereas humans using manual controls can and do make mistakes. At the same time, with DevSecOps, application changes flow freely through DevOps pipelines, giving developers more autonomy and authority without compromising security or elevating risk.
To be clear, DevSecOps is an evolution of DevOps culture and thinking. Rather than disrupting your current cyber agenda, it actually embeds many of the security processes, capabilities, and intelligence learnt over the years into your underlying platforms and toolchains. Building on your experience of developing and operating applications, DevSecOps enables you to automate good cybersecurity practises into the toolchain so they are utilised consistently.
The DevSecOps trend is only beginning to gather steam. For its 2018 DevOps Pulse Report, Logz.io surveyed more than 1,000 IT professionals worldwide about the state of DevOps in their industries. Roughly 24 per cent of respondents indicated their IT organisations were practising some DevSecOps elements. The other 76 per cent said their IT organisations either do not practise DevSecOps or are still in the process of implementation.1
Notably, 71 per cent of respondents feel that their teams currently lack adequate working knowledge of DevSecOps practises.2 During the next 18 to 24 months, expect that working knowledge to grow markedly as more CIOs and development leaders explore DevSecOps opportunities. Likewise, those with more advanced DevOps programmes in place may begin implementing governance, maximising automation, and cross-training both DevOps and cybersecurity specialists with new processes and tools.
DevOps’ fundamental value is speed to market.3 Organisations that do not incorporate security into every phase of their development and operations pipelines risk leaving much of its value on the table. Every product you stand up should be a known entity—tested, secure, and reliable. Internal and external users should not have to waste time grappling with cyber surprises, nor should you.
It’s time to stop playing the patch management game with security.
Even as IT organisations began embracing agile development practises over the last decade, many continued to approach security issues in the same incremental, siloed way they had with waterfall.4 Building on agile’s nimble, team-based approach to development, DevOps is now driving dramatic increases in end-to-end velocity. Yet with its heavy reliance on legacy processes and manual controls, security remains a challenge. In many DevOps pipelines, security is still treated as a bolt-on rather than a design feature. This can create pipeline bottlenecks, in part because few developers and system operators have cyber expertise and even fewer cyber specialists possess a deep understanding of development and operations. As a result, DevOps teams and cyber specialists continue to work separately within the pipeline, often slowing progress.
Increasingly, CIOs and DevOps leaders understand that unless these groups work as a unified team to bake security into products throughout the development and operations cycles, their companies may never realise DevOps’ full promise.5
DevSecOps is not a security trend in and of itself but, rather, an aspect of the ongoing DevOps revolution that Tech Trends has chronicled in past issues.6 It is also more of a mindset than a formal set of rules and tools. DevSecOps offers companies practising DevOps a different way of thinking about security. Consider the following characteristics of DevSecOps, and how they differ from the way you are approaching security in your development pipeline today:
Taken together, these DevSecOps elements can help improve the overall quality of security, boost productivity, and reduce compliance issues. Importantly, they can break the bottleneck that traditional security creates in high-velocity development environments, thus unleashing DevOps' full potential.
DevSecOps incorporates secure culture, practises and tools to drive visibility, collaboration and agility into each phase of the DevOps pipeline. Though companies can tailor their security approaches to support their own cyber agendas and product needs, DevSecOps initiatives typically rest on four foundational pillars:
Like any other IT programme, DevSecOps should directly tie to your broader IT strategy—which, in turn, should be driven by your business strategy. If a DevOps programme supports your IT and business strategies, then embed the “Sec” at the same time. In short order, it may help you bolster your cyber maturity posture and save you from having to rework your DevOps programme later when it’s much harder to do.
The National Institute of Allergy and Infectious Diseases (NIAID) works to keep us all safe by conducting and supporting research to prevent infectious, immunologic and allergic diseases. Within NIAID, the IT organisation is working to “future-proof” itself and provide timely and secure support to researchers and staff who conduct and manage key research projects. While the agency has used DevOps to ensure faster delivery of its software solutions, its need to protect sensitive health data has resulted in a vision for automated security everywhere and led to DevSecOps—the next logical step to DevOps.
“I think of DevSecOps as three legs of a stool: management practises, technological practises and cultural practises,” says Joe Croghan, chief of NIAID’s software engineering branch.8 “The cultural piece is the most challenging, though: You ask teams for transparency, to admit mistakes and to change continuously; it can be a lot for people to get their arms around.” Croghan believes the change is vital to ensure continued productivity in the face of rapid change and that it has enabled his team to continue to quickly respond to requests with secure products.
Long software release cycles were causing bottlenecks in delivering technology solutions at NIAID, compounding the existing challenges of the rapidly changing security landscape. Implementing DevOps practises—continuous integration and continuous delivery, automated testing and infrastructure-as-code—has helped shorten the lead time to deliver software and to patch critical defects. Infrastructure-as-code practises reduce vulnerabilities by making some aspects of security, such as application and server configurations, inspectable. And integrating security scanning tools like Fortify into the DevSecOps pipeline stops coding vulnerabilities from getting to production in the first place.
“The challenges we’ve always had with security are consistency, predictability and putting security policies into a systematic framework,” Croghan says. “By implementing a DevSecOps approach, we can run scans and put specific, consistent security protocols in place. When we’re using these techniques, we can be very confident in what our servers look like and if there’s a problem, we can fix it consistently by changing the code.”
In the coming year, Croghan hopes to address some of the cultural and management changes that are crucial to sustaining the team’s DevSecOps momentum. Staff and customers now see the value of the new approach and have been pleased with the speed of new application deployment, with the software engineering team completing more than 250 automated deployments in a month. But Croghan aspires to change the culture and do much more. “I think a year from now we will continue to adopt new technologies,” he says, “but we need to change the way we work. The culture of DevSecOps is to constantly measure, reevaluate and change.” These changes include aligning behaviours by educating his staff on delivering secure code within a DevSecOps framework and exceeding his customers’ expectations of software delivery, security and velocity.
Security and safety lie at the heart of everything the US Food and Drug Administration does. Each day, the agency’s 17,500 employees work diligently to ensure the safety and efficacy of the United States’ food supply, pharmaceuticals, medical devices, cosmetics and more. Amid recent calls for the agency to accelerate the process by which approvals occur, teams throughout the agency are working to strike the right balance between speed and safety.
Given the criticality of this mission, the FDA needs to support the security, privacy and stability of its IT systems at speed. To this end, the Centre for Biologics Evaluation and Research (CBER) has launched an ambitious DevSecOps initiative to reengineer its approach to security throughout the product development process. Although the project is still in the early stages, its goals are clear: 1) build in security upfront rather than treating it as an afterthought, 2) automate as much as possible and 3) transform the agency’s development culture into one that emphasises agility and speed.
According to senior IT project manager Christopher Kiem, DevSecOps represents a significant opportunity to get everyone working on the same page from the start of every project. “On day one, we want our operations talent to provide security insights and guidance to our developers in what we hope will become a loop of continuous conversation in which everyone is learning from each other,” he says.
This project loop will include inputs from security automation tools as well. A static code analysis tool will scan the source code for security issues. Application scanners will review open-source library files for security issues. Upon detecting problems, all of these tools will open issues for developers and DevSecOps engineers to assess and resolve.
These and other DevSecOps tools will streamline the overall development process and accelerate the pipeline. “When project managers come up with new system requirements, critical development tools, processes and automation will already be in place,” Kiem says. “This will make it possible for project managers to make decisions quickly. Our goal is to eliminate the meetings, emails and back-and-forth that slow people down.”
Currently, the CBER is performing a modernisation analysis to identify the different pieces and parts—data standards, regulatory rules, submission types, stakeholders, among others—to include in a formal game plan. This plan will also identify the DevOps elements already in place that can be leveraged. In the coming months, CBER’s IT leadership will present the plan to the Centre’s management to solicit their input and secure their sponsorship. “Once we have backing for the project, we will begin assessing our technology needs and developing plans for putting a pipeline in place,” Kiem says. “We will also be working closely with our enterprise IT partners to design a DevSecOps architecture that fills any current infrastructure gaps and supports our priorities.”
The priorities to which Kiem refers are not limited to software development and enhanced product security. Indeed, with DevSecOps he sees a tangential opportunity to reengineer core systems and, in doing so, keep the agency’s costs in cheque. “I think that across the public and private sectors, there are opportunities to decrease expenditure on IT. As you reengineer development processes to enhance security and quality, you can use this opportunity to consolidate your technology footprint. When things are humming along in a well-developed pipeline and you are releasing the products your users want, you should no longer need your less secure legacy systems, the massive suites of tools and the time required to support and enhance them. Imagine being able to get rid of all those things—and the costs related to them.”9
Maersk, like many other industrial organisations, has become digitally dependent - for operational efficiency and as the driver into new products, offerings and markets. Maersk has always been a forward-looking business, but we have a heightened focus today in part because of a global cyberattack in 2017 that infected our network across ports and offices across dozens of countries. As part of the recovery, we rebuilt our core IT capability, including reconstructing server and network infrastructure, moving more than 60,000 devices to a new common standard, deploying global operating system upgrades, restoring our entire application stack and restarting the world’s most automated terminal, all in a matter of weeks. We now have one of the most standardised environments of any company in the industry - a foundation that’s letting us deliver change at the pace of digital business.
Given the ever-changing cyber landscape, we’re building an even more secure and reliable infrastructure that can support the future growth of Maersk. We’re focusing on automated toolchains, building relevant static and dynamic scanning processes into our continuous integration and deployment processes. We’ve adopted post-deployment monitoring through production and we’ve been able to go from writing a line of code to deploying it in production with no human touch. That’s posed some interesting challenges across the organisation: When do you do a product release? With such rapid churning and changing, at what point do you declare it a new version? Currently, we’re spending a good deal of time exploring these concepts, making DevSecOps a core area of interest.
We’ve asked our CISOs to identify the gaps we have in our infrastructure as well as the compensating controls available to address those gaps. One of the main things we’ve done in the last two years is move the governance of risk from a central corporate function to a CISO function, so the CISO makes policy as well as enforces it. I want them to kick down the door where there’s an area of the business that “doesn’t have any risk,” because that’s just not possible. CISOs work with business owners to make deliberate decisions and business owners can decide how to address the existing risks when they are contained within their functional geography. It’s a consultative approach, but it’s consultation with teeth.
To that end, our CISO may not be a standing member, but there’s not a quarterly audit committee meeting where he’s not on the agenda. At our supervisory board, every other update has some cyber topic associated with it. We show the board a funnel diagram representing the number of attacks on the external surface, the penetrations, all incidents and then the major incidents - not to show them what we are doing but, rather, to demonstrate that our processes are working. We want them to understand that if the external surface attacks go from 200 to 800 a week, they should be asking us questions; if they see an increase in those that are penetrating, we want a dialogue to ensue about how we can handle the uptick. We want non-technologists as well as IT leaders to understand there is a minimum level of control and recoverability that should be in place if and when we fail to stop a future attack. With their support, we can control the amount of damage done and speed our recovery.
In this environment, I don’t think it’s an either/or approach when it comes to traditional waterfall development, DevOps, integrated toolchains and agile delivery. We still organise our people under traditional plan-build-run structures, with functional homes organised around technology or IT life cycle capabilities. But we deploy our people in a DevSecOps model aligned to products, platforms and initiatives. This enables all areas of the business to gain from improvements in any area, across all activities. Without a functional home for people to return to, you’re constantly churning people and process, which means you’re failing to improve them each time. For example, I don’t want every one of my global teams solving for automated regression testing. So we implemented a centre of excellence that provides team members the tools, thinking and models they need to complete their tasks. This model has allowed us to increase in maturity and capability, while deploying applications in a more modern, diverse fashion.
This model only works, however, if everyone around the leadership table understands the inherent value in the technology organisation. Maersk is a digital business and we are incapable of operating if the technology does not work correctly, so our business leaders need to understand what’s at stake. You need a degree of trust, openness and desire in all the players around the table to play as a single team. I knew we’d achieved that at Maersk when I proposed a reduction to the technology budget and my peers argued against the notion, fearing we’d miss out on too much value. I think that’s the target for which we’re all aiming for: complete understanding of how security and DevSecOps can impact business outcomes.
My goal is to have anyone around the executive table capable of leading the technology function in a few years. This would reflect that operations and the underlying technology stack have stabilised and that the business leaders are tech-savvy enough to step in and lead the charge. But the real test will be if they strive to take roles in which technology enablement responsibilities are as recognised and as important as leading sales or a line of business. We’re well on our way.
For PayPal, with more than 254 million active account holders and over 7.5 billion payment transactions in 2017, security and trust are central to everything we do and what our customers expect. As such, we treat security as a strategic business priority and a fundamental part of how we develop, release and maintain our product code, integrating it by default into every layer, throughout the entire development life cycle.
For me, DevSecOps means not only empowering our developers with the tools necessary to develop high-quality, secure software, but also creating a culture that builds secure products by default. With our company, customer base and transaction volume growing so fast, we need security at scale: As of 2017, PayPal had 4,500 developers, 50 million lines of code, 1 million builds per month, 2,600 apps, nine availability zones, 230 billion hits and 42,000 batch executions per day! We give developers as much control as possible over their code and its outcomes to help them achieve this scale. When you offer developers flexibility and autonomy, it is important to build a talent base that lives and breathes your security mantra. We’ve worked to create a culture in which developers understand that successful products require an equal appreciation of development, security and operations. That’s been our journey: to meet security, availability and quality needs while enabling high-velocity code releases.
We adopted an agile methodology at the start of our journey and we’re currently transitioning to DevSecOps. We try to find balance between development and operations by providing tools that make every step - from ideation to releasing code - frictionless for developers. We empower them with the freedom to use our recommended tool suite, the “opinionated path,” which includes security penetration testing, auto-enabled security controls, threat modelling, automated scanning and other features. But we also believe developers shouldn’t be forced to use a specific tool suite, so we give them the autonomy to follow an un-opinionated path and bring their own stack. We provide the tools and processes they need to deploy code while meeting our security, availability and quality standards. This way of working under a DevSecOps framework is resulting in better performance and productivity for our developers. We are also seeing a reduction in potential vulnerabilities and improvements in maintaining product security standards - a result of ingraining risk-based thinking and processes within the DevOps pipeline.
Our primary focus now is to stand up an autonomous fleet of development, operations and security tools that we can maintain virtually hands-free. There’s tremendous value in being able to run scans and end-to-end tests on a minute-by-minute basis, deploy patches through automation, identify potential vulnerabilities at regular intervals and ensure that applications are meeting standards, including configuration changes or vendor interface updates in production. Automating these processes is key for scaling a 200,000-plus-node fleet with speed and consistency while holding all deployments and processes to the same security and quality standards.
Our security and compliance automation have been helpful in related areas, as well. Our focus on automation has made it easier to address the complexities of legal and compliance obligations and policies, given that we operate in more than 200 global markets. With the nature of our business, security and trust will remain a core capability and priority for PayPal. It doesn’t matter what size company you are—if you build in security at your core, it will serve your business well.
Embedding security into DevOps pipelines may initially seem like a straightforward proposition. After all, if DevSecOps is just a way of thinking about security, then deploying it in your DevOps factory should be a light lift, right? For those few who have fully mastered DevOps, perhaps. For everyone else—and that is most organisations—developing DevSecOps practises will likely be another component in existing DevOps initiatives that are still in early stages. For example, in its 2018 Global Developer Report, GitLab surveyed roughly 5,300 IT professionals about their DevOps experiences. Thirty-five per cent of respondents said the DevOps culture at their companies was “somewhat established.” Only 23 per cent of those surveyed would go so far as to describe their development method as DevOps.10
As you explore DevSecOps opportunities, ask yourself the following questions not only about security but about how they may affect your current DevOps efforts.
Will I have to hire developers with security expertise?
Not necessarily. First, work to turn the combined knowledge of the security expert and the developer into code. Next, upskilling existing talent may be the only viable staffing option as the DevSecOps trend progresses, but it allows you to retain important business knowledge gained over the years from each respective area. Besides, developers with security expertise (and vice versa) are in high demand right now and increasingly hard to recruit (and keep).11
Won’t DevSecOps slow down my pipeline?
Probably not. Granted, if you had no security controls prior to DevSecOps, there will be some efficiency trade-off, but DevSecOps provides two major efficiency benefits: 1) Incorporating security into a DevSecOps pipeline still results in a faster pipeline than the waterfall method and 2) DevSecOps gets faster as time moves forward because vulnerabilities are mitigated over time and efficiency increases. Developers also gradually gain more freedom and autonomy to move product through the pipeline because of automated controls.
Can DevSecOps be compatible with my compliance requirement?
Yes—if anything, it helps ease the burden of maintaining compliance. In an ideal DevSecOps state, security auditing, monitoring and notification are fully automated and continuously monitored, enhancing compliance.
My DevOps process is still immature. How can I make sure that my DevSecOps governance is scalable?
Plan, storyboard and start small. Sustainable and scalable DevSecOps governance models typically feature the following components:
The ever-growing need to get quality products out the door faster has elevated DevOps practises to the position they hold today in the arena of software development. In a natural extension of DevOps evolution, the DevSecOps trend offers CIOs and their development teams a new mix of tools, practises and automation that, deployed in concert, can help secure development and operations.
