We’ll discuss how a security team works towards a mission.
- Mission: Reducing risks, increasing trust, and complying with governance.
- Work: Balancing effort across business needs, operations, engineering, and incidents.
This section should help a new manager tackle existential questions about what security is trying to accomplish, and how.
Security work may not feel like like it directly contributes to a mission. This writing will help sharpen that sense.
A mission for the security team
Security teams may define how their mission relates to the organization. The overall organization’s mission is often simple. Often, a sentence or two.
The mission is unlikely to spells out all of the laws, risks, ethics, and other constraints it operates within; To do so would weaken the mission’s purpose of simplicity and memorability.
A simple, agreeable mission has the power to align a group of individuals towards a north star.
However, aspects of quality are lost in simple mission statements. A security team carries these values for the organization, as other teams may carry their own.
A security team typically aims to:
- Reduce risks.
- Increase trust.
- Comply with governance.
The mission of a security team tries to capture and articulate some amount of these motivations.
Risk based missions hope to reduce the frequency and impact of undesirable scenarios.
These scenarios may injure the company or impose harm on others (e.g., customers). Our organizations, customers, or society can experience harm in a variety of forms.
Trust missions aim to improve the perception of risk that others have of your organization.
Trust may improve the efficient pursuit of goals (revenue, customers, renewals, etc.). An effort to build trust may sound similar to the management of risk. Not always. Customers can distrust an organization that manages its risks. Customers can trust an organization on reputation alone. These strategies are not honest, desirable, or even efficient.
Governance missions seek to adhere to laws, contracts, and regulations that may impose some level of requirements on how an organization operates.
These missions intermingle. All pursuit of these missions produces work for an organization. The concept of work is crucial to these essays. We’ll discuss how work occurs within each of these motivations by examining each idea individually.
A risk is an undesirable future scenario with consequences. Here is an example:
An insider accesses our customer service tools and steals customer data.
Security teams are chiefly concerned with mitigating a complex constellation of risk scenarios like these.
A security team wouldn’t exist without risk. If a security team cannot describe the risks they are concerned about, we might question where they’ve gotten their original direction. Direction without any defined risks can lead to directionless organizations. We should start with risks.
We can build a risk based, foundational view of what an organization does and what motivates it. The reduction of risk should be a core principle for the mission of a security team. Risks generate the work a security team undertakes.
Let’s work on our previous insider scenario. We might create particular work tasks to mitigate that risk. Here are some common examples:
- Reduce the number of employees with access to production.
- Centralize logging from production administrative tools.
- Delete customer data after 30 days.
Assuming these are good ideas, the security team is now off and running doing security work. The work was derived from the risk scenario we used in our example.
Trust is the perception of risk associated with our organization. Any organization may hope to build trust in others: Customers, partners, consumers, etc.
Unique organizations are exposed to trust issues more than others.
A social website will see reduced engagement and adoption if there’s a belief that their privacy guarantees are not predictable.
A SaaS platform might not pass a security review if a customer believes the response to a security questionnaire is not representative of reality.
A hardware manufacturer might have reduced sales if customers believe that a backdoor exists in the product.
A security team can choose work that has the potential to build trust. Trust is a delicate subject that is often considered an intangible. KPI selection and precision measurement of trust is a difficult task.
Trust still appears in second-order measurements. Here are some example questions:
- Will transactions increase if we switch our payment processor?
- How often do users quit if they see spam on our platform?
- How many sales conversations churn because we lack at-rest encryption?
A laser focus on trust can result in narrow, unauthentic tasks aimed at influencing these metrics. For example, a growth team may be interested in adding a “certification” badge on a sign-up or payment form. Or a lock icon. Was that effort worth it?
Narrow trust tasks are less efficient as ones that can also reduce prioritized risks. For instance, a blog post describing a risk they’ve mitigated may also build trust amongst readers. Sometimes we see security teams blogging about their open-source contributions as an example of this efficiency at work.
Trust is often a byproduct of transparency from an organization’s risk reductions. An honest focus on risk reduction will often have opportunities for making these improvements transparent.
A security team will burn out unless they are working efficiently on both trust and risk.
Additionally, trust increases by mitigating the risks imposed on others. An organization may only be concerned with risks to itself. A customer relying on this self-interested organization may experience risks being imposed on it.
Let’s take an example SaaS platform. This company may have a robust security program intent on securing its customer’s data at rest. The customer may still be concerned with what risks it has to manage by using the platform.
Here are some example reasons:
- Customer is limited to a single, shared user account for use across many employees.
- The customer has no logs available to investigate an incident with the platform.
- Customers cannot restrict confidential information to their employees.
These sorts of product decisions limit a customer’s ability to manage their risks. The company may reduce their risks of a potential incident, the customer cannot effectively their own.
These risks are imposed and left for the customer to handle.
Markets that require a higher level of trust (larger enterprise) can be more easily accessed when customers can manage their risks. Listen to customers for opportunities to self-manage risk.
Our institutions impose risk reductions on one another.
- Laws influence us to behave within constraints.
- Contracts address requirements before a party enters a relationship.
- Regulations impose restrictions on the industry.
Any organization is often subject to a patchwork of these forms of governance. Compliance frameworks exist to gather up a complex set of requirements and standardize them. Frameworks may simplify a governance situation while also introducing complexities of their own.
Rather than eliminating the work, security teams often own a function called “Governance, Risk Management, and Compliance” or GRC. Their goal is compliance to this constellation of governance sources.
In theory, a compliant organization:
- Has reduced risks. A compliant organization is a secure one.
- Has increased trust. A compliant organization is a trustworthy one.
In practice, compliance frameworks, laws, and regulations may not reduce the most critical risks that concern an organization. Additionally, compliance with some standard or framework may also build negligible trust among a market you operate it.
An approach to governance should be aware of how it can also manage risks to the business and build trust amongst a customer base while performing activities it already has to govern itself.
This level of efficiency isn’t always possible. Some compliance needs are outlandish and cannot be reasonably bypassed. This doesn’t excuse good prioritization: always make sure that risk and trust is forefront in compliance work.
Note: Negative views of governance-driven security teams are widespread. These views describe governance as authoritarian, friction based, and prescriptive. Leadership should be on the lookout for these patterns, and should screen candidates that may contribute to this perception.
How does a security team work?
We can describe how a security team works day to day as types of work. These types can apply to most organizations, large or small. What’s work, anyway?
Work applies to anything where our team spends time and effort.
Work is loosely defined. You know it when you’re doing it. Work may be a project, a commitment, an opportunity, or a process.
Work makes us busy.
We can categorize work into four buckets. Three are planned, and one is unplanned.
This model is based on lessons popularized by The Phoenix Project.
- Business Projects: How does security help with new business efforts?
- Operations: What ongoing tasks are security engineers committed to accomplishing?
- Engineering: How does security make investments for a better future?
- Incidents (Unplanned): What takes attention from planned work?
To simplify, we’ll use the example of a farm:
- Business project: Build a new barn, buy animals, and hire a farmhand.
- Operations: Feed the animals daily.
- Engineering: Pave a concrete path to more easily move equipment.
- Incidents and unplanned: Wolves ate the chickens. Repair fence.
We’ll move to discuss these as security team concepts.
A security team often finds itself supporting a business’s efforts towards a mission or objective. Work piles up for security at the business’ request.
We can approximate what a security team will have tasks for by exploring how the business grows.
For example, leadership may plan a new office. The plans immediately cause security work. Security may need to install appliances or configure networks at the location before employees arrive.
Another example might be a vendor relationship. The business might intend to purchase a service from a vendor. Security might tag along to manage risks associated with it with contracts, access control, or how data transits.
A final example: A business might be launching a new software product. A security team will get involved to reduce vulnerabilities to the company or consumers using it. Security requires collaborative work on product decisions or various types of assessments to find and fix bugs.
A defining factor of business projects is that security can anticipate involvement and plan their involvement.
Business projects are planned work. Planned work can be staffed and resourced effectively, unplanned work is thrown together in a panic.
A decision to mitigate a risk might commit a security team to own operational work. Operational work comes in many forms. We can better predict how much work a security team holds by exploring what it is regularly committed to performing.
An infrastructure environment might be too complex to understand its risks fully. A security team might rely on detection to gain certainty that no adversaries are creeping around. Though, what happens when something is detected? A detection pipeline might require an on-call employee to respond to alerts. Detection commitments create operational work. Now, the rotation and scheduling of an on-call to respond to alerts is the resulting operational work.
The follow-up work from vulnerability scanning. It makes little sense to scan for vulnerabilities in any environment and never return to scan again. Things change! The regularity a security team commits to managing vulnerabilities becomes operational work predicated on that regularity.
A final example might be a security awareness program. A typical output of these programs is training. We hope employees are suspicious of certain behaviors and escalate them to security. These are rarely one-and-done efforts and categorize easily into operational work, especially as employees are onboarded.
Operational work, while necessary, is often a target to be minimized or eliminated through automation. Operational work can become a difficult management and performance subject as a result. A realistic view of KPI’s and performance management can help deter operational work from being used as an unrealistic proxy for risk reduction.
Operational work must relate to the reduction of risk. Work with a low impact on risks may contribute to the feeling of toil in operational work, as does repetitive work.
Additionally, opportunities to eliminate operational toil will surface with engineering practices that we’ll discuss next.
No organization wants to repeat tasks for too long. A principle of any good organization is to become more efficient. A security team often invests in itself to expand its ability to support the business and eliminate toil. The result should be more efficient business projects, operations, and reduced incidents or unplanned work.
I will use examples to highlight engineering’s effect on other types of work.
- Integrating static analysis into a build pipeline may discover issues in business projects quicker.
- Automating the analysis of suspicious emails to reduce the amount of operations time spent investigating benign links.
- Segmenting an untrustworthy part of the network exposed to a vendor may reduce unplanned incidents.
Effective security engineering builds towards reducing the entire organization’s risks, as opposed to solely making their own lives easier. Additionally, project work is often the most desirable for a talented engineer.
It’s for this reason that strong, well-directed engineering organizations will eventually shift environments away from toil (repetitive, low impact, or unplanned work) and into engineering projects.
A security team should push for a positive project workload that increases efficiency and keeps heads above water.
Lastly, we have incidents and other unplanned work.
Incidents and Unplanned
Unplanned work is a broad term that counts all distractions from planned work—included as a special case is incident response. Incidents are straightforward to plan for, but difficult to predict the work they’ll create when they occur. As a result, there is often some amount of toil involved.
It’s through unplanned work that we can develop an organization. Unplanned work guides the resources and tasks to shift work into planned work we can anticipate. A case for headcount or budget is easiest with a demonstrated need to manage unplanned work that regularly rears its head.
Organizations make predictions about where unplanned work may rear its head. Predictions generate work in all three areas: business projects, operations, and engineering. These predictions would have to be accurate to successfully shift left from unplanned work into planned work.
This ties types of work together—a clear, upward relationship forms from transitioning unplanned work into planned work.
- Business projects hope to protect an expanding business.
- Operations runs the commitments made in protecting the business.
- Engineering makes it more efficient to support business projects, perform operational work, and avoid risks.
- Should any of these efforts fail to anticipate problems; they become unplanned work.
The resulting unplanned work then is where learning begins. Those lessons bring us back into improving business projects, operations, and security engineering.
- Unplanned work inspires business projects, operations, and security engineering.
- Business projects and security operations feed work into engineering.
- Engineering projects march toward a better state of being.
Foundations in practice
Every security team has problems. A perfect strategy is unobtainable.
The risks at every organization are different. Missions are different. Technology choices are different. The management principles that leadership may subscribe to will be different.
As organizations grow, the security team may come together slowly, first from brave souls stepping up. Then, expanded headcount by headcount. A team may come to realize that a security team was never really founded at a precise time or direction. Rather, the team was more of a culmination of ad-hoc tasks and self-directed projects.
Early incidents often influence team-building decisions as well. Frequent re-organizations and M&A’s are also highly disruptive to the trajectory of a team. Large customers can also be an outsized voice in what a security team looks like to have their needs addressed in a contract.
All of these dynamics pull us away from idealist views of a security team. Security teams all work towards a larger mission by tackling risk, trust, and governance issues. These concepts are only a north star. A north star is helpful with distractions but does not eliminate them.
As a result, security teams are never as clean-cut as this writing might suggest they could be.
Next, imbalances in work are also very common. Teams drown themselves with operational work (alerts, vulnerabilities, tickets) or overly focus on pet project work. There is no prescribed balance for these, other than making sure engineering projects help diminish the efforts involved with business projects, operations, or incidents. Having the terminology to discuss friction points in terms of work allows an organization to find this balance. We’ll discuss some of the efforts to find this balance next with management.
