Episode 23 — Use business operations knowledge to select telemetry that matters most

In this episode, we’re going to connect two ideas that beginners often keep separate in their minds: how a business actually runs day to day, and what signals a Security Operations Center (S O C) should collect to spot trouble early. When someone first hears the word telemetry, it can sound like a purely technical topic, as if the right answer is always to gather the most detailed logs possible from every device. The reality is that the value of telemetry depends on whether it helps you protect what the organization depends on, and that requires understanding how money is made, how services are delivered, and where the organization would feel pain if something breaks. Business operations knowledge is not about being a finance expert or a manager, because it is about knowing what workflows keep the lights on and what systems and identities are essential to those workflows. Once you can link telemetry to the business story, you can choose signals that reduce uncertainty in the moments that matter, instead of collecting a mountain of data that is expensive, noisy, and hard to use.

Before we continue, a quick note: this audio course is a companion to our course companion books. The first book is about the exam and provides detailed information on how to pass it best. The second book is a Kindle-only eBook that contains 1,000 flashcards that can be used on your mobile device or Kindle.

The first step is to clarify what we mean by business operations knowledge, because it is not a vague concept and it is not a fancy term meant to impress people. Business operations knowledge is the practical understanding of how work gets done, such as how customers place orders, how staff access systems, how approvals happen, and what dependencies exist between teams and services. It includes knowing which systems are customer-facing, which systems support internal productivity, and which systems hold sensitive information like payments, personal data, or proprietary designs. It also includes knowing what normal looks like, such as typical login patterns for staff, normal seasonal spikes in activity, and routine administrative changes that happen during maintenance windows. When you bring this knowledge into telemetry selection, you shift from collecting what is easy to collect to collecting what is meaningful to defend. That shift is central to effective monitoring because it keeps your attention on impact, not just on technical curiosity.

Telemetry matters most when it answers questions that are hard to answer under pressure, and business knowledge helps you predict which questions will show up during an incident. For example, if a customer service workflow depends on a specific application and identity system, then a sudden login anomaly or permission change in those areas is more important than a minor warning on a less critical system. If a revenue-generating system must be available at all times, then telemetry about performance degradation, unusual spikes, or repeated failed access attempts becomes a security concern because it could signal abuse or disruption. If the business relies on vendors or partners, then telemetry around third-party access, remote connections, and account usage becomes essential because those pathways can be abused. Beginners sometimes believe security monitoring starts with attackers, but it often starts with understanding what the business cannot afford to lose. Once you know what matters, the telemetry you choose becomes more targeted, more defensible, and more likely to create useful alerts.

A useful mental model is to think of telemetry as evidence you might need later, because that frames selection as preparation rather than collection for its own sake. Evidence needs to show who did what, where they did it, when it happened, and what changed as a result, and those questions align closely with business operations. Who often ties back to identities, roles, and access levels, which are defined by business processes like hiring, onboarding, and job responsibilities. What ties back to actions that affect business outcomes, like changes to pricing rules, updates to customer records, or configuration changes to services that support transactions. Where ties back to which systems or environments were involved, including whether activity touched production systems, customer data stores, or administrative consoles. When ties back to time, including whether the activity happened during a planned change window or at an unusual hour for the role involved. If your telemetry cannot support these simple evidence questions, investigations become slower and more uncertain, which is exactly what you want to avoid.

Business operations knowledge also helps you identify the most important identities to watch, because access is often the real center of gravity in modern incidents. Organizations have many accounts, but not all accounts carry the same risk, and the difference usually comes from what the account can do in business terms. Accounts tied to payroll, billing, vendor payments, and customer management often have direct business impact because they can trigger money movement or expose sensitive records. Privileged administrative accounts matter because they can change security settings, disable logging, or create new access paths, and those actions can hide an attack in plain sight. Service accounts matter because they often run behind the scenes with steady permissions, and if they are abused, the activity can blend into normal automated behavior. Business operations knowledge helps you understand which roles are high-value targets and which roles have unusual access patterns that should stand out if something changes. When telemetry selection highlights identity activity for these areas, you gain earlier and clearer signals of meaningful risk.

Another place where business context improves telemetry selection is in understanding the critical paths of services, which are the sequences of systems and steps that must work for key outcomes to happen. A critical path might be the flow from a customer login to a purchase, or from an employee authentication to access of an internal tool, or from a device connection to a sensitive database. If you know the critical path, you can choose telemetry that covers the key transitions, such as authentication events, authorization decisions, and high-impact actions within the systems that complete the workflow. This coverage prevents a common monitoring mistake where you collect a lot of detail inside one system but miss the boundary events where security decisions actually occur. Boundaries are where users authenticate, where systems talk to each other, and where permissions are evaluated, and those are also where attackers try to pivot. Telemetry that captures boundary behavior tends to be high value because it helps you see the story of access across systems. In practice, business operations knowledge tells you which critical paths are worth protecting with deeper visibility.

Business knowledge also helps you spot where data sensitivity is highest, which changes what telemetry you want and how you want to handle it. If a system stores personal data, payment details, health information, or confidential business plans, then telemetry needs to capture access patterns and administrative changes more carefully because unauthorized access is a major impact event. At the same time, you must consider privacy and the principle of collecting only what you need, because security monitoring should reduce risk, not create new risk by copying sensitive data into additional places. This is where selection becomes thoughtful rather than aggressive, because you might prefer telemetry that captures access decisions and metadata about actions rather than capturing the content of sensitive records. Business operations knowledge helps you differentiate between the need to know that a record was accessed and the temptation to capture what the record contained. That distinction is important for governance, for trust, and for keeping the monitoring system itself from becoming a sensitive data warehouse. Telemetry that balances visibility with responsible collection is a hallmark of a well-run program.

It is also important to recognize that business operations explain what normal variability looks like, which is critical when deciding which telemetry signals will be meaningful. Many systems behave differently during month-end closing, holiday shopping periods, product launches, or major marketing campaigns, and those shifts can look suspicious if you do not understand the business calendar. For example, a surge in customer logins during a promotion might be normal, while a surge in administrative changes during that same period might be unusual and risky. A spike in support staff access during an outage might be expected, while the same spike at an odd hour with unusual geography might deserve attention. Telemetry is only useful when you can interpret it against a baseline of expected behavior, and business operations knowledge provides the reason behind the baseline. Without that context, monitoring can become a constant stream of false alarms that desensitizes the team. Selecting telemetry with an understanding of normal business rhythms helps you build detections that are both sensitive and practical.

Business operations knowledge can also guide you to telemetry that captures changes, not just events, because many high-impact incidents involve something being altered rather than simply accessed. Changes to payment destinations, changes to user permissions, changes to security settings, changes to integrations, and changes to customer account details can all be security-critical because they can enable fraud, cover tracks, or disrupt services. Beginners sometimes focus on login events and forget that what happens after a login is often the real problem, especially if an attacker has stolen a legitimate account. Telemetry that records configuration changes, administrative actions, and policy updates provides a clearer view of whether access was used responsibly or abused. Business context helps you prioritize which changes matter most by asking which changes could cause real damage if performed incorrectly or maliciously. It also helps you identify which systems have change processes that should be reflected in the data, such as approvals, maintenance windows, and documented releases. When telemetry aligns with expected change processes, anomalies stand out more clearly and investigations become more efficient.

A practical way to apply business operations knowledge is to map telemetry to business risk scenarios, not as a formal exercise but as a habit of thinking. If the business worries about downtime, then telemetry about availability, service errors, and unusual traffic patterns becomes important because it can reveal disruption attempts. If the business worries about fraud, then telemetry about account changes, payment workflows, and unusual transaction patterns becomes important because it can show manipulation. If the business worries about data exposure, then telemetry about access to sensitive stores, large exports, and permission escalations becomes important because it can reveal leakage paths. Each scenario points to a different set of signals, and the best collection plan includes at least a baseline for the most relevant scenarios. This is not about predicting every attack, but about collecting the evidence that would let you quickly confirm or deny the most damaging possibilities. Business operations knowledge makes these scenarios more realistic because it highlights what the organization truly values. When you choose telemetry this way, you are prioritizing signals that shorten the time between suspicion and certainty.

Another key idea is that telemetry should support triage, which is the early decision-making step where an analyst determines whether something needs urgent action or simple documentation. Triage depends on context, and context is often business-owned information, such as asset criticality, service ownership, and role-based access expectations. If telemetry includes identifiers that let you tie an event to a specific system, a specific user role, and a specific business service, then triage becomes faster and more consistent. Without that, analysts waste time figuring out whether a system is important, whether an account is privileged, or whether an action is expected for that team. Business operations knowledge helps you insist on collecting telemetry that can be connected to this context, because you know what questions will be asked in the first five minutes of an investigation. It also helps you recognize the difference between interesting technical anomalies and business-relevant anomalies that justify attention. In a well-designed monitoring program, telemetry is chosen not only for deep investigation but also for quick sorting of what matters right now. That is how you keep the S O C focused and sustainable.

Business context also informs how you handle tradeoffs, because not every useful signal is equally feasible to collect at full detail. Some telemetry sources are expensive, some are high-volume, and some are sensitive, and you may need to start with a lighter approach that still provides meaningful coverage. For example, you might start with summaries of access patterns rather than capturing highly detailed traces, especially if you are still learning what normal looks like. You might prioritize collecting events for the most critical systems first, then expand as you validate value and tune detections. You might choose to collect metadata fields that support correlation, such as user identifiers, device identifiers, and event types, while avoiding unnecessary content that increases privacy risk. Business operations knowledge helps you explain these tradeoffs clearly, because you can tie them to business needs and constraints rather than presenting them as arbitrary technical limitations. This is important because telemetry collection is not just a technical project, it is a cross-functional decision that affects costs, risk, and trust. When your choices are grounded in operations, they are easier to defend and easier to improve over time.

It is also worth reviewing how business operations knowledge influences where you look for gaps, because gaps are not simply missing logs, they are missing visibility into important workflows. A gap might mean you cannot see administrative changes on a critical platform, or you cannot reliably trace a user action across systems in a transaction flow. It might mean you have authentication logs but no record of high-impact actions after authentication, leaving you unable to confirm what an account actually did. It might mean you collect network data but cannot connect it to business services, so you see traffic but cannot judge importance. Business operations knowledge helps you rank these gaps by asking which missing visibility would cause the most confusion during an incident that threatens core outcomes. That focus keeps gap analysis from turning into a checklist exercise where you try to collect one of everything. Instead, you learn to pursue the gaps that block decisive response, because those are the gaps that increase damage and recovery time. When you build the habit of finding workflow gaps, your telemetry program becomes more aligned with real needs and less driven by volume.

As we wrap up, keep the central review idea in your mind: telemetry selection is strongest when it is guided by how the business operates, not by what is technically possible. The organization’s workflows, critical paths, sensitive data locations, and high-impact identities define where security visibility matters most, and those operational realities should shape what you collect and how you prioritize it. When you use business context, you can choose signals that support fast triage, confident investigation, and responsible handling of sensitive information without drowning the S O C in noise. You also gain a clear way to explain tradeoffs, because you can connect costs and constraints to business priorities rather than treating them as technical excuses. Over time, this mindset creates a monitoring program that grows intelligently, filling the gaps that block decision-making and strengthening the signals that reveal meaningful risk. If you remember one thing for the exam and for practice, remember that good telemetry is not the most telemetry, but the telemetry that most reliably explains what is happening to the business systems that matter.
