“The biggest exposure was the Death Star,” a member of the Ivanti team recently told attendees at a GovEvents and Carahsoft hosted Webinar on exposure management.
The webinar and the messenger: Ivanti and Derek Illum
The comment came during a GovEvents and Carahsoft webinar titled “Beyond Patch Management: Proactive Exposure Management for a Modern Threat Landscape,” in which Ivanti solutions architect Derek Illum outlined how traditional vulnerability workflows leave large, complex environments exposed. Illum used the Death Star anecdote to make a practical point: a single, shared insider vulnerability can undermine an otherwise formidable defense.
Know Your Unknowns: asset discovery as the starting point
Illum argued that the modern attack surface has grown far beyond the laptops and servers that drove legacy patching programs. “There are other things that you have to be aware of... cloud and containerization and social media,” he said, and those elements can affect awareness. Because organizations can only remediate what they can see, Illum called asset discovery “essential” and described it as “the start for any and all exposure management or vulnerability remediation practice.”
Where historical approaches relied on deployed agents or software to validate resources, Illum said, unmanaged or unregistered devices can still be present on networks. Modern exposure management, he said, uses comprehensive mapping and network scans to find such resources and to surface authentication or credential issues that would otherwise be missed.
Combining multiple sources of truth into an environment map
Illum described exposure management platforms as more than scanners. They “combine numerous sources of truth to build out a much clearer, more detailed map of the network.” Discovery tools are intended to be merged with entitlements, billing systems, consumption reports and asset management solutions to create a master record of endpoints and to identify what is or isn’t managed.
That consolidated environment map, he said, “essentially reflects what your attack surface looks like, and that attack surface is where remediation occurs.”
Exposure management lifecycle and the problem of handoffs
Illum described the “exposure management lifecycle” as historically inefficient because of a disjointed handoff between security and operations. “The legacy exposure management life cycle is cumbersome and time consuming,” he said. In his depiction, the security team may take several days to identify exposures, then need another week or two to prepare the data for the operations team; remediation tracking often falls to spreadsheets or email chains.
Those silos, Illum argued, hinder prioritization and slow remediation. Exposure management’s promise, he said, is to “bring together these parts of the organization” so vulnerability fixes happen in the right order and at the right pace.
Cover the exhaust port FIRST: prioritization and limited resources
Illum used the Death Star’s exposed exhaust port as a shorthand for prioritization: if an organization must triage vulnerabilities, it should fix the most critical, most exploitable exposures first. He framed prioritization as working “backward” from the most valuable resources and the most likely avenues of exploitation.
He emphasized that modern exposure management tools can automate and streamline that prioritization, creating what he called a “tactical risk funnel” so agencies can “maximize the impact of the limited time that their security and operations teams have.” Illum linked that need to current workforce constraints, noting agencies are “forced to do more with less following layoffs across the federal government and extended hiring freezes intended to reduce government spending on employees and personnel.”
What this means for government agencies, security teams, and operations teams
- Government agencies should invest in tools that build an environment map by combining discovery with billing, entitlements and asset records, because visibility is a precondition for remediation.
- Security teams need to shorten the identification-to-handoff timeframe: Illum described discovery taking “several days” and data preparation another “week or two,” delays that modern exposure management platforms aim to collapse.
- Operations teams must act on prioritized guidance; Illum framed remediation as a joint function and warned that tracking via spreadsheets or email undermines speed and clarity.
Ivanti’s message is concise: find what you don’t know, map it accurately, and allocate scarce human effort to the exposures that matter most. If a single uncovered exhaust port could doom a galaxy-class weapon, Illum’s takeaway for government cyber defenders is simply to learn that lesson before an adversary writes the exploit.
