Seeing clearly: How exposure management streamlines SOC investigations

In this article:

When a data breach or a ransomware attack takes place, incident-response teams often lack full context and visibility into how assets and identities connect across the environment. If they can't see how an attacker can jump from one compromised asset to another, or which crown jewels may be at risk, any containment efforts will be incomplete.

Exposure-management platforms are proactive, not reactive, yet they are valuable tools in adequately preparing SOC teams for worst-case scenarios. They can close information gaps by providing a unified inventory of assets and identities that reveals critical relationships, potential attack paths and remediation choke points — all before an attack occurs.

For more information:

Using the total visibility and context that exposure management offers, incident responders can hit the ground running when the alerts go off. The team can now quickly assess threats, disrupt attacks, prioritize fixes, determine material impact — and reduce the likelihood of further successful compromises.

Panic mode

Every good SOC team prepares for security incidents, but as Mike Tyson once said, everyone has a plan until they get punched. Without adequate information about the systems being attacked, the nature of the attack and the criticality of the vulnerable assets, any response will be insufficient.

In the meantime, alarm bells are going off in the SOC and team members are scrambling to put together all the information they need, but they often can't see how all the various parts of the environment interact and impact each other.

"One of the challenges these teams face is that the SIEM tools collect telemetry data, but lack relationship context," explains Pierre Coyne, Director of Product Marketing for the Tenable One exposure-management platform. "The result is many alerts flooding the SOC. They then have to go to different tools to piece together how all these individual alerts may be related, and what the potential impact may be."

Nor can SIEM or SOAR tools adequately track the potential blast radius of a compromised identity, the leading vector for successful intrusions per the 2025 Verizon Data Breach Investigations Report. Overly generous identity permissions and system privileges grow like weeds in mature environments, posing a latent threat that many SOC teams maybe be unaware of.

"If an identity is phished, SOC teams have no idea what that identity had access to and how [an attacker] could move around the environment and disrupt the business," says Coyne.

Meanwhile, regulations like HIPAA, PCI-DSS, GDPR and, most recently, the SEC's updated Systems Compliance and Integrity rules mandate timely reporting of what the SEC calls "material" breaches that could impact on business or customer data.

"When an incident does occur," says Coyne, "incident teams don't know if there has been a material impact to the organization, and must spend days sometimes looking for information from different tools to piece together what happened."

Proper preparation is the best response

Exposure management puts all the crucial information together ahead of time so that incident-response teams can spend their time fixing what's important instead of guessing what that might be.

As part of its process of finding every potential flaw in an environment, an exposure-management platform will perform a thorough, automated asset inventory, and not just of software and hardware. Identities and their permissions are catalogued as well.

"This isn't just a list of IPs and hostnames," says a recent Tenable blog post. "A true exposure management platform creates a rich, contextualized view by aggregating data from all of your sensing tools ؅— including those from Tenable as well as third-party, cloud, identity and OT systems."

Each asset is not only inventoried, but its criticality to the organization's business is estimated, its connections to other assets mapped out, and its ownership attributed. Identity roles are defined and privileges are listed.

"For a compromised identity, we can see what devices that user has access to," Coyne explains. "Are there any exploitable risks on those devices? What attack paths are related to the user or device that lead to crown-jewel assets?"

From there, the platform uses its understanding of the entire environment to map out potential attack paths that lead to crown-jewel assets. It links vulnerabilities, misconfigurations, compromised identities and other weaknesses that may have seemed unimportant on their own but could be devastating when chained together.

"Whether it's a storm of alerts generated by anomalous activity, or a user that was phished and called into the service deck to report it, staff can drill into deep asset and user information instantly with exposure management and get rich technical and business context," Coyne says.

This wealth of information makes clear which assets are most important and how their compromise could affect normal business processes. From there, it's a short step to full compliance with reporting rules and regulations.

"If a breach does occur, SOC teams must understand if it represents a material impact to its customers, or to investors," explains Coyne. "Depending on the regulations like GDPR, SEC or others, the organization must disclose these often within 2-4 days. If they can see how attackers can use weakness and what they can get to, then can quickly assess if it is a material breach."

Again, an exposure-management tool does not detect or respond to incidents. It does not locate attackers or eradicate malware. Instead, it gives you a holistic view of your entire environment and all the ways an adversary might get into it to reach your organization's most valuable assets — invaluable knowledge for an incident-response team to possess in the minutes after the intrusion alerts start to go off.

"The goal is to see your organization not as you've built it, but as an attacker sees it -- as a web of interconnected opportunities," the Tenable blog post says. "The most powerful capability of a mature exposure-management program is the ability to visualize these connections as potential attack paths."
