1. What is a cybersecurity plan and why do you need it?
Developing a cybersecurity plan is not a simple process; it requires expertise, resources, and diligence. Even a simple plan may involve several months of development, more depending on the complexity involved. The time it takes to develop the plan may also be impacted by how much executive support is provided, the size of the development team (bigger is not always better), and how available required resources are.[1]
2. What are the major standard and regulations dictating cybersecurity action?
3. The NIST Cybersecurity Framework and its control families
4. Fitting a framework or specification into a cybersecurity plan
5. Develop and create the cybersecurity plan
What follows is a template to help guide you in developing your own cybersecurity plan. This template has at its core a modified version of the template structure suggested in the late 2018 Cybersecurity Strategy Development Guide created for the National Association of Regulatory Utility Commissioners (NARUC).[1] While their document focuses on cybersecurity for utility cooperatives and commissions, much of what NARUC suggests can still be more broadly applied to all but the tiniest of businesses. Additional resources such as AHIMA's AHIMA Guidelines: The Cybersecurity Plan[4]; National Rural Electric Cooperative Association (NRECA), Cooperative Research Network's Guide to Developing a Cyber Security and Risk Mitigation Plan[2]; and various cybersecurity experts' articles[3][5][6][7][8][9] have been reviewed to further supplement the template. This template covers 10 main cybersecurity planning steps, each with multiple sub-steps. Additional commentary, guidance, and citation is included with those sub-steps.
Note that before development begins, you'll want to consider the knowledge resources available and key stakeholders involved. Do you have the expertise available in-house to address all 10 planning steps, or will you need to acquire help from one or more third parties? Who are the key individuals providing critical support to the business and its operations? Having the critical expertise and stakeholders involved with the plan's development process early on can enhance the overall plan and provide for more effective strategic outcomes.[1]
Also remind yourself that completing this plan will likely not require a straightforward, by-the-numbers approach. The most feasible outcome will have you jumping around a few steps and filling in blanks or revising statements in previous portions of the plan. While the ordering of these items is deliberate, completing them step by step may not make the best sense for your organization. Don't be afraid to go back and update sections you've worked on previously using new-found knowledge.
5.1. Develop strategic cybersecurity goals and define success
5.1.1 Broadly articulate business goals and how information technology relates
Something should drive you to want to implement a cybersecurity plan. Sometimes the impetus may be external, such as a major breach at another company that affects millions of people. But more often than not, well-formulated business goals and the resources, regulations, and motivations tied to them will propel development of the plan. Business goals have, hopefully, already been developed by the time you consider a cybersecurity plan. Now is the time to identify the technology and data that are tied to those goals. A clinical testing laboratory, for example, may have as a business goal "to provide prompt, accurate analysis of specimens submitted to the laboratory." Does the lab utilize information management systems as a means to better meet that goal? How secure are the systems? What are the consequences of having mission-critical data compromised in said systems?
5.1.2 Articulate why cybersecurity is vital to achieving those goals
Looking to your business goals for the technology, data, and other resources used to achieve those goals gives you an opportunity to turn the magnifying glass towards why the technology, data, and resources need to be secure. For example, the clinical testing lab will likely be dealing with protected health information (PHI), and an electric cooperative must reliably provide service practically 100 percent of the time. Both the data and the service must be protected from physical and cyber intrusion, at risk of significant and costly consequence. Be clear about what the potential consequences actually may be, as well as how business goals could be hindered without proper cybersecurity for critical assets. Or, conversely, clearly state what will be positively achieved by addressing cybersecurity for those assets.
5.1.3 Based on the above, state the cybersecurity mission and define how to achieve it
You've stated your business goals, how technology and data plays a role in them, and why it's vital to ensure their security. Now it's time to develop your strategic mission in regards to cybersecurity. You may wish to take a few extra steps before defining the goals of that mission, however. The NARUC has this to say in that regard[1]:
Establishing a strategic [mission] is a critical first step that sets the tone for the entire process of drafting the strategy. Before developing [the mission], a commission may want to do an internal inventory of key stakeholders; conduct blue-sky thinking exercises; and do an environmental assessment and literature review to identify near-, mid-, and long-term drivers of change that may affect its goals.
Whatever cybersecurity mission goals you inevitably declare, you'll want to be sure they "provide a sense of purpose, identity, and long-term direction" and clearly communicate what's most important in regards to cybersecurity to internal and external customers. Also consider adding concise points that paint the overall mission as one dedicated to limiting vulnerabilities and keeping risks mitigated.[1]
5.1.4 Gain and promote active and visible support from executive management in achieving the cybersecurity mission
Ensuring executive management is fully on-board with your stated cybersecurity mission is vital. If key business leaders have not been intimately involved with the process as of yet, it is now time to gain their input and full support. As NARUC notes, "with leadership buy-in, it will be easier to institutionalize the idea that cybersecurity is a priority and can result in more readily available resources."[1] Consider what AHIMA calls a "State of the Union" approach to presenting the cybersecurity mission goals to leadership, being prepared to answer questions from them about responsible parties, communication policies, and "cyber insurance."[4] (Answers to such questions are addressed further into this template. You may wish to have some of what follows informally addressed before taking it to leadership. Or perhaps have an agreement to keep leadership appraised throughout cybersecurity plan development, gaining their feedback and overall acceptance of the plan as development comes to a close.)
5.2 Define scope and responsibilities
5.2.1 Define the scope and applicability through key requirements and boundaries
Now that the cybersecurity mission goals are clear and supported by leadership, it's time to tailor strategies based on those stated goals.
How broad of scope will the mission goals take you across your business assets? Information technology (IT) and data will surely be at the forefront, but don't forget to also address operational technology (OT) assets as well.[1] One helpful tool in determining the strategies and requirements needed to meet mission goals is to clearly define the logical and physical boundaries of your information system.[1][2] When considering those boundaries, remember the following[2]:
- An information system is more than a piece of software; it's a collection of all the components and other resources within the system's environment. Some of those will be internal and some external.
- The system is more than just hardware; the interfaces—physical and logical—as well as communication protocols also make up the system.
- The system has physical, logical, and security control boundaries, as well as data flows tied to those boundaries.
- The data housed and transmitted in the system is likely composed of varying degrees of sensitivity, further shaping boundaries.
- The information system's primary functions are directly tied to the goals of the business.
Additionally, when considering the scope of the plan, you'll also want to take into account advancements in both technology and cyber threats. "Unprecedented cybersecurity challenges loom just beyond the horizon," states CNA, a nonprofit research and analysis organization located in Arlington, Virginia. But we have to focus on more than just the "now." CNA adds that "today's operational security agenda is too narrow in scope to address the wide range of issues likely to emerge in the coming years."[10] Just as CNA is preparing a global initiative to shape policy on future cybersecurity challenges, so should you apply some focus to what potential technology upgrades may be made and what new cyber threats may appear.
Finally, some of the plan's scope may be dictated by prioritized assessment of risks to critical assets—addressed in the next section—and other assessments. It's important to keep this in mind when developing the scope; it may be affected by other parts of the plan. As you develop further sections of the plan, you may need to update previous sections with what you've learned.
5.2.2 Define the roles, responsibilities, and chain of command of those enacting and updating the cybersecurity plan
You'll also want to define who will fill what roles, what responsibilities they will have, and who reports to who, as part of the scope of your plan. This will include not only who's responsible for developing the cybersecurity plan (which you'll have hopefully determined early on) but also implementing, enforcing, and updating it. Having a senior manager who's able to oversee these responsibilities, make decisions, and enforce requirements will improve the plan's chance of success. Having clearly defined security-related roles and responsibilities (including security risk management) at one or more organizational levels (depending on how big your organization is) will also improve success rates.[1][2][8][9]
5.2.3 Ensure that roles and responsibility for security (the “who” of it) are clear
Defining roles, responsibilities, and chain of command isn't enough. Effectively communicating these roles and responsibilities to everyone inside and outside the organization—including third parties such as contractors and cloud providers—is vital. This typically involves encouraging transparency of cybersecurity and responsibility goals of the organization, as well as addressing everyday communications and education of everyone affected by the cybersecurity plan.[1][2][8] However, through it all, keep in mind for future communications and training that ultimately security is everyone's responsibility, from employees to contractors, not just those enacting and updating the plan.
