Plan and implement a security strategy across teams
Shifting to the cloud for security is more than a simple technology change, it's a generational shift in technology akin to moving from mainframes to desktops and onto enterprise servers. Successfully navigating this change requires fundamental shifts in expectations and mindset by security teams. Adopting the right mindsets and expectations reduces conflict within your organization and increases the effectiveness of security teams.
While these could be part of any security modernization plan, the rapid pace of change in the cloud makes adopting them an urgent priority.
Partnership with shared goals. In this age of fast paced decisions and constant process evolution, security can no longer adopt an "arms-length" approach to approving or denying changes to the environment. Security teams must partner closely with business and IT teams to establish shared goals around productivity, reliability, and security and work collectively with those partners to achieve them.
This partnership is the ultimate form of "shift left"---the principle of integrating security earlier in the processes to make fixing security issues easier and more effective. This requires a culture change by all involved (security, business, and IT), requiring each to learn the culture and norms of other groups while simultaneously teaching others about their own. Security teams must:
Learn the business and IT objectives and why each is important and how they're thinking about achieving them as they transform.
Share why security is important in the context of those business goals and risks, what other teams can do to meet security goals, and how they should do it.
Security is an ongoing risk, not a problem. You can't "solve" crime. At its core, security is just a risk management discipline, which happens to be focused on malicious actions by humans rather than natural events. Like all risks, security isn't a problem that can be fixed by a solution, it's a combination of the likelihood and impact of damage from a negative event, an attack. It's most comparable to traditional corporate espionage and criminal activities where organizations face motivated human attackers who have financial incentive to successfully attack the organization.
Success in either productivity or security requires both. An organization must focus on both security and productivity in today's "innovate or become irrelevant" environment. If the organization isn't productive and driving new innovation, it could lose competitiveness in the marketplace that causes it to weaken financially or eventually fail. If the organization isn't secure and loses control of assets to attackers, it could lose competitiveness in the marketplace that causes it to weaken financially and eventually fail.
No organization is perfect at adopting the cloud, not even Microsoft. Microsoft's IT and security teams grapple with many of the same challenges that our customers do such as figuring out how to structure programs well, balancing supporting legacy software with supporting cutting-edge innovation, and even technology gaps in cloud services. As these teams learn how to better operate and secure the cloud, they're actively sharing their lessons learned via documents like this along with others on the IT showcase site, while continuously providing feedback to our engineering teams and third-party vendors to improve their offerings.
Opportunity in transformation. It's important to view digital transformation as a positive opportunity for security. While it's easy to see the potential downsides and risk of this change, it's easy to miss the massive opportunity to reinvent the role of security and earn a seat at the table where decisions are made. Partnering with the business can result in increased security funding, reduce wasteful repetitive efforts in security, and make working in security more enjoyable as they will be more connected to the organization's mission.
As an architect you need to ensure all teams are aligned to a single strategy that both enables and secures enterprise systems and data.
Security strategy principles
Watch the video below for an overview about the Security Strategy principles:
Security roles and responsibilities
Business and technology outcomes are traditionally driven using a plan/build/run framework (which is becoming increasingly agile for digital transformation with rapid iteration through all stages). Security Outcomes are driven through a similar framework of governance, prevention and response that maps to that framework. This also maps to the NIST Cybersecurity framework of identify, protect, detect, respond, and recover functions. The diagram below shows how security roles map to business outcome enablement:
Security Leadership Roles and Security Architect Roles provide vision, guidance, and coordination across the organization and technical estate.
Security Posture and Compliance Roles focus on identifying security risks across the enterprise and work with subject matter experts to ensure the top risks are mitigated. The responsibility of these roles typically includes Security Compliance Management, Policy and Standards, and Posture management.
Platform Security Engineers are security subject matter experts (SMEs) that focus on enterprise-wide systems like identity and key management, and various infrastructure and endpoint disciplines like Network security, Server/VM security, and Client endpoints/devices.
Application Security Engineers are security SMEs that focus on securing individual workload and applications, often as they're developed. These responsibilities include per-workload application of infrastructure and endpoint skills as well as application security & DevSecOps and Data security. We expect that demand will continue to increase for these skillsets as digital transformation increases adoption of Cloud technology, DevOps/DevSecOps models, and Infrastructure as Code approaches.
People Security is an emerging discipline that focuses on educating people, protecting them, and protecting the organization against insider risks.
The operational phase is executed by a combination of operations teams who are responsible for the production environments (IT & OT Operations, DevOps) + Security Operations teams.
Security Operations typically focuses on reactive Incident monitoring & response and proactive Threat Hunting for adversaries that slipped past detections. Threat Intelligence and Incident preparation functions are often incubated in security operations, but then shift to a broader scope as they mature and become integrated into technology and organizational processes.
Creating a healthy Feedback loop is critical to effectiveness in all parts of security (and in maturing security processes). We expect the relationship between prevention and response to continue to get closer as teams increasingly automate technical processes and adopt DevOps style processes focused on rapid agile iteration.
Security strategy considerations
Security helps create assurances of confidentiality, integrity, safety, and availability for a business. Security efforts have a critical focus on protecting against the potential impact to operations caused by both internal and external malicious and unintentional acts. The diagram below shows that security is integrated as part of the cloud adoption process and from the beginning (defining the strategy), security is taking into consideration.
Adhering to these steps will help you integrate security at critical points in the process. The goal is to avoid obstacles in cloud adoption and reduce unnecessary business or operational disruption.
Effective security in the cloud requires a strategy that reflects the current threat environment and the nature of the cloud platform that's hosting the enterprise assets. A clear strategy improves the effort of all teams to provide a secure and sustainable enterprise cloud environment. The security strategy must enable defined business outcomes, reduce risk to an acceptable level, and enable employees to be productive.
A cloud security strategy provides guidance to all teams working on the technology, processes, and people readiness for this adoption. The strategy should inform the cloud architecture and technical capabilities, guide the security architecture and capabilities, and influence the training and education of teams.
Build and implement a security strategy for cloud that includes the input and active participation of all teams. While the process documentation format can vary, it always includes:
Active input from teams: Strategies typically fail if people in the organization don't buy into them. Ideally, get all teams in the same room to collaboratively build the strategy. In the workshops we conduct with customers, we often find organizations have been operating in de facto silos and these meetings often result in people meeting each other for the first time. We find that inclusiveness is a requirement. If some teams aren't invited, this meeting typically has to be repeated until all participants join it. If they don't join, then the project doesn't move forward.
Documented and communicated clearly: All teams must have awareness of the security strategy. Ideally, the security strategy is a security component of the overall technology strategy. This strategy includes why to integrate security, what is important in security, and what security success looks like. This strategy includes specific guidance for application and development teams so they can get clear, organized guidance without having to read through non-relevant information.
Stable, but flexible: Keep strategies relatively consistent and stable, but the architectures and the documentation might need to add clarity and accommodate the dynamic nature of cloud. For example, filtering out malicious external traffic would stay consistent as a strategic imperative even if you shift from the use of a third-party next generation firewall to Azure Firewall and adjust diagrams and guidance on how to do it.
Start with business alignment: Security teams will address many strategy issues large and small, but you need to start somewhere. We recommend establishing alignment to business goals and risk as the north star and starting point for the security strategy. This may be challenging at first, but by starting with concrete questions like "what would you restore first if all business systems were down?" you can start building relationships while establishing quick wins.
The strategy step should result in a document that can easily be communicated to many stakeholders within the organization. The stakeholders can potentially include executives on the organization's leadership team.
We recommended capturing the strategy in a presentation to facilitate easy discussion and updating. This presentation can be supported with a document, depending on the culture and preferences.
Strategy presentation: You might have a single strategy presentation, or you might choose to also create summary versions for leadership audiences.
Full presentation: This should include the full set of elements for the security strategy in the main presentation or in optional reference slides.
Executive summaries: Versions to use with senior executives and board members might contain only critical elements relevant to their role, such as risk appetite, top priorities, or accepted risks.
You can also record motivations, outcomes, and business justifications in the strategy and plan template.
Best practices for building security strategy
Successful programs incorporate these elements into their security strategy process:
Align closely to business strategy: Security's charter is to protect business value. It's critical to align all security efforts to that purpose and minimize internal conflict.
Build a shared understanding of business, IT, and security requirements.
Integrate security early into cloud adoption to avoid last-minute crises from avoidable risks.
Use an agile approach to immediately establish minimum security requirements and continuously improve security assurances over time.
Encourage security culture change through intentional proactive leadership actions.
Modernize security strategy: The security strategy should include considerations for all aspects of modern technology environment, current threat landscape, and security community resources.
Adapt to the shared responsibility model of the cloud.
Include all cloud types and multicloud deployments.
Prefer native cloud controls to avoid unnecessary and harmful friction.
Integrate the security community to keep up with the pace of attacker evolution.
|Accountable team||Responsible and supporting teams|
|Security leadership team (chief information security officer (CISO) or equivalent)||Cloud strategy team|
|Cloud security team|
|Cloud adoption team|
|Cloud center of excellence or central IT team|
Executives and business leaders with accountability for outcomes or risks of business lines within the organization should approve this strategy. This group might include the board of directors, depending on the organization.
