Introduction: Two Organizations, One Attack, Two Completely Different Outcomes
Cybersecurity is often measured by the tools an organization owns: endpoint detection platforms, firewalls, identity protection, cloud monitoring, SIEM systems, and increasingly sophisticated security operations centers. But a new assessment from the U.S. Cybersecurity and Infrastructure Security Agency (CISA) demonstrates why technology alone is not enough.
In its August 25, 2026 advisory AA26-237A, “A Tale of Two SOCs,” CISA described simultaneous red team assessments against two critical infrastructure organizations. The attackers used broadly similar tradecraft against both environments, and the exercises ultimately demonstrated that both organizations contained serious weaknesses in Active Directory, cloud security, credential management, and privileged access. Yet their defensive outcomes were dramatically different.

One organization, identified as Organization A, failed to detect the red team’s activity. The attackers moved through its environment, reached sensitive business systems, compromised the domain, accessed cloud resources, and even monitored security-team communications without triggering an effective response.
The second organization, Organization B, had many of the same underlying weaknesses. But its security team detected the initial intrusion attempts within minutes, isolated affected workstations, and disrupted command-and-control communications before the simulated attack could develop normally.
The difference is the heart of
CISA Tested Two Critical Infrastructure Environments
CISA conducted the assessments against two organizations from different critical infrastructure sectors. Organization A belonged to the Government Services and Facilities Sector, while Organization B operated in the Water and Wastewater Systems Sector.

The assessments were designed to resemble realistic adversary behavior rather than simply testing whether individual security products could identify isolated indicators. The red team attempted to move through traditional IT infrastructure, Active Directory, sensitive business systems, cloud resources, and, where possible, operational technology environments.
The results were striking because neither organization had a completely secure environment.
Both contained weaknesses that could potentially allow an attacker to move from a relatively ordinary foothold toward highly privileged access. Both had problems involving credentials, identity infrastructure, and privileged permissions.
But only one organization was able to turn its security technology into an effective defensive response.
Organization A: When Security Alerts Become Background Noise
The assessment against Organization A began with a deceptively simple weakness: a web application containing default credentials for several built-in accounts.
That mistake gave the red team an initial foothold and allowed it to send phishing messages from an internal address. The simulated attackers subsequently reached four workstations, providing them with opportunities to continue expanding their access.
The lesson is uncomfortable because the initial weakness was not necessarily an exotic zero-day. It was a basic security hygiene problem that created an opening into a much larger environment.
Default Credentials Opened the First Door
Default credentials remain one of the most persistent security problems in enterprise environments because they can transform a forgotten application or appliance into an attacker-controlled launching point.
Once the red team discovered the vulnerable configuration at Organization A, it was able to use the compromised position to send convincing internal phishing messages.
This demonstrates an important escalation pattern: an attacker does not always need to compromise every system individually when one trusted system can be turned into a source of further attacks.
An email originating from inside an organization can carry a level of credibility that an external message may never achieve.
Active Directory Became the Highway to Privilege
After gaining access to workstations, the red team turned toward Active Directory.
CISA reported that the assessment uncovered two particularly important weaknesses: a default Machine Account Quota (MAQ) configuration and a misconfigured Active Directory Certificate Services (AD CS) certificate template.
Together, these weaknesses created a pathway toward privilege escalation and eventually domain-level compromise.
AD CS is especially important because certificate-based authentication can provide powerful access when certificate templates are improperly configured. CISA’s findings show why organizations cannot treat certificate infrastructure as a secondary administrative concern.
The Danger of an Overlooked Machine Account Quota
The Machine Account Quota controls how many computer accounts an ordinary domain user can create.
Leaving this setting at its default can create opportunities for abuse because users may be able to add machine accounts that can subsequently become useful in attack chains.
The problem is not simply that a single configuration is insecure. The bigger danger comes from chaining multiple ordinary weaknesses together.
An attacker who combines identity misconfigurations, certificate-template problems, excessive permissions, and exposed credentials can turn what appear to be isolated findings into a path toward complete domain compromise.
AD CS Misconfiguration Added Another Escalation Path
CISA identified an ESC1-style AD CS configuration weakness at Organization A.
In simple terms, an improperly configured certificate template could allow certificate requests to be made on behalf of other identities under conditions that should have been restricted.
This type of weakness matters because certificates can become an alternative authentication mechanism. If an attacker can obtain a certificate representing a privileged identity, traditional password protections may no longer provide sufficient protection.
The broader lesson is clear: identity security is no longer just about passwords.
Certificates, tokens, service principals, workload identities, machine accounts, application permissions, and cloud refresh tokens all need to be treated as potential authentication pathways.
Cleartext Credentials Turned Internal Systems Into Attack Resources
The red team also discovered credentials stored in cleartext on reachable systems.
CISA reported that sensitive credentials appeared in places such as decrypted database configuration files. Static AWS access keys were also present and configured without expiration.
This created an additional avenue into sensitive business systems.
Cleartext credentials are particularly dangerous because they can remain invisible to conventional perimeter defenses. A firewall may correctly block an external attacker while an attacker already inside the network simply searches accessible systems for secrets.
Once valid credentials are discovered, the attacker may not need to exploit another vulnerability at all.
Static Cloud Keys Created a Second Problem
The assessment also demonstrated why cloud credentials require the same level of protection as traditional administrative passwords.
Organization A had static AWS access keys that were configured never to expire. CISA also highlighted insufficient mechanisms for revoking tokens after compromise.
A credential that remains valid indefinitely effectively gives an attacker a potentially permanent opportunity unless defenders manually intervene.
Cloud environments therefore require lifecycle management, privilege minimization, monitoring, and rapid revocation procedures rather than simply storing credentials securely once and assuming the problem is solved.
Entra ID Extended the Attack Beyond the Local Network
The red team did not stop with traditional infrastructure.
It obtained a Primary Refresh Token and abused applications in Microsoft Entra ID that possessed elevated permissions. This allowed the team to access security-team email and determine whether defenders had discovered the simulated intrusion.
That is an especially revealing moment in the assessment.
The attackers were not merely inside the network. They were effectively looking at the defenders’ own communications.
Once attackers can observe security operations, the defensive advantage begins to disappear.
Organization A’s Biggest Weakness Was Not a Firewall
CISA said Organization A failed to detect the red team’s activity.
The organization had multiple SOCs and endpoint security technologies, but the different teams and tools did not provide sufficiently shared visibility.
At the same time, thousands of false-positive alerts generated by ordinary business activity created an enormous amount of background noise.
Some of those alerts were rated at relatively high severity, making it even more difficult for analysts to distinguish genuine malicious behavior from routine activity.
This created a classic alert fatigue problem.
When everything looks urgent, nothing receives the attention it deserves.
A Real Alert Was Dismissed as a False Positive
Perhaps the most damaging example involved activity associated with a System Center Configuration Manager, or SCCM, server.
A legitimate alert connected to the red team’s activity was reportedly dismissed because defenders could not identify the system’s owner.
That single example illustrates the difference between detection and response.
The security system generated information.
The human organization failed to convert that information into action.
A technically accurate alert therefore became operationally useless.
Organization B Told a Very Different Story
The same broad style of attack produced a dramatically different result at Organization B.
When phishing payloads executed, its SOC detected the activity and isolated affected workstations within approximately 2 to 20 minutes.
That rapid response prevented the red team from maintaining the same initial foothold and disrupted command-and-control communications.
The organization did not necessarily have a perfectly hardened environment.
Instead, it demonstrated something equally important: the ability to interrupt an attack before every weakness can be chained together.
Detection Changed the Entire Assessment
Because Organization B cut off the initial foothold, CISA had to change the methodology.
Trusted personnel at the organization executed a red team payload on a designated non-privileged host so the assessment could continue under an assume-breach model.
This distinction matters.
Organization B still contained serious security weaknesses. The assessment was therefore not a story about a perfectly protected network.
It was a demonstration of what happens when defenders can identify and contain the first stage of an intrusion.
Organization B Still Had Serious Identity Weaknesses
Once the assessment continued from an assumed-compromise position, the red team discovered problems similar to those found at Organization A.
For example, a domain service
That account had significant privileges over a domain controller.
This demonstrates why rapid detection should not be mistaken for complete security.
A company can successfully stop one attack path while still possessing structural weaknesses that another attacker could exploit later.
DCSync Demonstrated the Consequences of Excessive Privilege
The red team used the compromised service
The krbtgt account is central to Kerberos authentication in Active Directory, making its compromise particularly serious.
This is one reason service-account privilege must be carefully controlled.
A service account should not automatically have the ability to perform high-impact directory operations merely because a legacy application or management platform requires elevated functionality.
Organization B’s OT Environment Added Another Layer of Defense
The red team also reached a bastion host located in Organization B’s operational technology DMZ.
However, that host did not have outbound internet access.
As a result, the team could not establish the expected command-and-control channel from that location, and the assessment did not progress into the organization’s OT systems.
This illustrates the value of segmentation and egress control.
Even if an attacker reaches a strategically important machine, the environment can still limit what that attacker is capable of doing.
Segmentation Can Buy Defenders Critical Time
The OT DMZ example is important because critical infrastructure environments cannot rely exclusively on endpoint detection.
Operational technology often has different availability and safety requirements from conventional IT.
Strong network segmentation, restricted outbound connectivity, carefully controlled administration paths, and monitoring between IT and OT can prevent an IT compromise from automatically becoming an operational disruption.
In other words, containment is itself a security control.
The Real Difference Was People and Processes
CISA’s central conclusion is arguably more important than any individual vulnerability.
The agency emphasized that detection tools are only effective when supported by the people, processes, and procedures required to interpret and act on their output.
CSIRTS.com
+1
Organization A had security technology but lacked sufficient coordination and response authority.
Organization B demonstrated that rapid human intervention could dramatically change the trajectory of the same style of attack.
The difference was not simply which organization owned the better product.
It was which organization could turn an alert into a decision, and a decision into an action.
The Three Major Lessons From CISA
CISA’s findings can be condensed into three broad defensive lessons: reduce alert noise, break down organizational silos, and strengthen cloud security.
CSIRTS.com
Each of these problems is common across modern enterprise environments.
More importantly, they reinforce one another.
Poor visibility creates alert noise. Alert noise slows analysts. Slow analysts struggle to coordinate. Poor coordination makes cloud incidents harder to contain. Cloud compromise then creates additional identities and access paths that defenders may not fully understand.
Alert Fatigue Is a Security Vulnerability
Organizations frequently measure security maturity by how many alerts their tools generate.
That can be the wrong metric.
A SOC generating thousands of alerts that analysts cannot investigate may be less effective than a smaller system producing fewer but higher-confidence detections.
The objective should not be maximum alert volume.
The objective should be maximum defensive value per analyst decision.
Organizations should establish baselines for normal behavior, continuously tune detections, eliminate recurring false positives, and prioritize signals that indicate meaningful changes in identity, privilege, lateral movement, or cloud access.
Security Teams Need Authority to Act
A detection is worthless if an analyst cannot isolate a machine, disable an account, revoke a token, block an application, or escalate an incident without navigating excessive bureaucracy.
Organization
An alert connected to a compromised SCCM server was reportedly dismissed because defenders could not establish ownership.
That is a process problem.
Organizations need clearly defined incident ownership, escalation procedures, system inventories, emergency contacts, and pre-authorized containment actions.
Cloud Security Must Be Treated as Incident Response
The assessment also highlights a growing problem in hybrid environments: organizations may have strong procedures for responding to compromised laptops but much weaker procedures for compromised cloud identities.
A stolen refresh token, service principal, workload identity, or cloud access key can provide access that survives the isolation of a physical workstation.
For that reason, incident response plans should explicitly include cloud identity compromise.
Teams should know how to identify suspicious application activity, revoke tokens, disable compromised identities, rotate credentials, remove excessive permissions, and investigate access across cloud services.
Defensive Commands: Audit Before You Change Anything
PowerShell: Check Machine Account Quota
A Windows security team can review the current Machine Account Quota with a read-only PowerShell query:
Get-ADDomain | Select-Object DNSRoot, DistinguishedName, ms-DS-MachineAccountQuota
The objective is not to blindly change the value.
First determine whether the current configuration is required for legitimate operations, identify who can create computer objects, and document exceptions.
Defensive Commands: Review AD CS Certificate Templates
PowerShell: Inventory Certificate Templates
Administrators can begin a controlled inventory of certificate templates with:
certutil -CATemplates
For deeper AD CS auditing, organizations should review which templates permit authentication, who can enroll, whether requester-supplied identities are permitted, and whether privileged identities are exposed to inappropriate enrollment paths.
These checks should be performed as part of an authorized security assessment rather than against systems an administrator does not control.
Defensive Commands: Find Stored Secrets
PowerShell: Search Carefully for Credential Exposure
A basic defensive review can identify suspicious configuration files without attempting to use discovered credentials:
Get-ChildItem -Path C:\ -Recurse -File -ErrorAction SilentlyContinue |
Where-Object { $_.Extension -in '.config','.xml','.ini','.json' } |
Select-Object -ExpandProperty FullName
Organizations should then inspect relevant files through approved security procedures and replace exposed credentials rather than merely deleting the visible password.
The real fix is credential rotation, secret management, and privilege reduction.
Defensive Commands: Review Microsoft Entra Applications
Microsoft Graph PowerShell
Security teams can inventory enterprise applications and service principals through Microsoft Graph PowerShell:
Get-MgServicePrincipal -All | Select-Object DisplayName, AppId, Id, AccountEnabled
The next step should be permission review.
Applications with broad access should have a documented business justification, and unused or excessive permissions should be removed.
Defensive Commands: Review AWS Access Keys
AWS CLI
Organizations using AWS can review access-key metadata with:
aws iam list-access-keys --user-name USERNAME
The goal is to identify long-lived credentials, unnecessary keys, and credentials that lack an appropriate rotation process.
Security teams should avoid embedding credentials in configuration files and should prefer temporary credentials and managed identity mechanisms where practical.
What Undercode Say:
The Most Important Finding Is Not the AD CS Problem
CISA’s assessment contains numerous technical weaknesses, but focusing exclusively on AD CS, Machine Account Quota, or DCSync would miss the larger message.
The report is fundamentally about defensive resilience.
Both organizations contained exploitable weaknesses.
Only one initially demonstrated the ability to stop the attack.
Security Products Cannot Compensate for Broken Processes
Organization A appears to have had multiple security tools and multiple SOC functions.
Yet those tools produced limited defensive value because visibility was fragmented and alert volume was overwhelming.
Buying another security product would not necessarily have solved the underlying problem.
The organization first needed better coordination, ownership, prioritization, and response authority.
Alert Quality Matters More Than Alert Quantity
A SOC should not celebrate an enormous alert count.
The better question is whether analysts can distinguish meaningful threats from normal activity quickly enough to make the right decision.
A security operation that generates 100,000 alerts but misses the important one has failed at its primary objective.
CISA’s findings make alert tuning a strategic security issue rather than a minor SIEM housekeeping task.
Identity Has Become the New Security Perimeter
The assessment repeatedly returns to identity.
Machine accounts.
Certificates.
Service accounts.
Database credentials.
AWS keys.
Primary Refresh Tokens.
Entra ID applications.
These are all different mechanisms, but they share a common characteristic: they provide access.
Modern defenders therefore need to think about identity pathways rather than simply network boundaries.
Hybrid Networks Create Hybrid Attack Paths
An attacker may begin with a web application, move to a workstation, escalate through Active Directory, steal credentials from SCCM, access cloud applications, and eventually approach an OT environment.
None of those steps necessarily belongs to a single traditional security category.
This is why security teams must connect endpoint, identity, network, cloud, and OT telemetry.
Attackers do not respect organizational boundaries.
Defenders cannot afford to either.
SCCM Deserves More Security Attention
System Center Configuration Manager can possess powerful administrative capabilities.
That makes configuration files and service accounts associated with management infrastructure particularly important security assets.
Credentials stored in management infrastructure should be treated as high-value secrets.
A compromised management platform can become a force multiplier for lateral movement.
The Cloud Is Not an Escape From Active Directory Risk
Moving applications into the cloud does not eliminate identity problems.
Instead, it creates additional identity systems and authentication mechanisms.
The assessment demonstrates how a traditional enterprise compromise can extend into cloud services through tokens and application permissions.
Cloud security therefore has to be integrated into the organization’s broader identity-security strategy.
Token Revocation Must Be Practiced
Having the theoretical ability to revoke a token is not the same as being able to do it during a crisis.
Incident responders should understand which tokens exist, which identities issued them, how they can be revoked, and what downstream systems may continue trusting them.
These procedures should be tested before an incident.
Least Privilege Must Include Applications
Organizations often think about least privilege in terms of human users.
That is no longer enough.
Applications, service principals, workload identities, automation accounts, and machine accounts can possess enormous permissions.
Every one of them should have a documented purpose and the minimum permissions required to perform that purpose.
OT Segmentation Remains One of the Strongest Safety Nets
Organization
The red team reached the bastion host but could not establish the required outbound command-and-control path.
That limitation prevented the simulated compromise from automatically crossing into the operational environment.
Segmentation does not make an organization invulnerable.
It can, however, prevent one compromised zone from becoming the entire organization’s compromise.
Egress Filtering Is Often Underestimated
Organizations frequently focus on preventing unauthorized traffic from entering their networks.
But outbound controls can be equally valuable.
If a compromised host cannot freely communicate with external infrastructure, attackers may have fewer options for maintaining command-and-control or moving stolen information out of the environment.
Egress restrictions can therefore turn an initial compromise into a contained incident.
Incident Response Speed Is a Security Control
The difference between two minutes and two hours can completely change an intrusion.
Organization
Speed is therefore not merely an operational metric.
It is part of the security architecture.
Human Judgment Still Matters
Artificial intelligence, automated detection, behavioral analytics, and advanced endpoint platforms can dramatically improve security operations.
But the final decision often remains human.
Someone must decide whether an alert represents an attack.
Someone must determine whether a workstation should be isolated.
Someone must identify which account should be disabled.
Someone must determine whether a cloud token needs to be revoked.
Technology can accelerate those decisions.
It cannot eliminate the need for them.
Security Ownership Must Be Obvious
A security analyst should never have to spend critical incident time asking who owns a sensitive server.
Asset ownership should be documented.
Business owners should be identifiable.
Technical contacts should be reachable.
Escalation procedures should be tested.
The organization should know who can authorize emergency containment.
These administrative details can become security controls during a real attack.
Critical Infrastructure Has Less Room for Error
Government services, water systems, utilities, transportation, healthcare, and other critical infrastructure environments have consequences that extend beyond stolen files.
A successful cyberattack can potentially affect public services, safety, continuity, and trust.
That makes the lessons from this assessment particularly significant.
The objective should not simply be preventing every intrusion.
It should also be ensuring that an intrusion cannot easily become a catastrophic operational event.
“Assume Breach” Should Become a Practical Discipline
Organization
That concept deserves more attention.
Instead of asking whether the organization can prevent every compromise, defenders should repeatedly ask:
What happens if the attacker gets in?
Which credentials can they find?
Which systems can they reach?
Which identities can they impersonate?
Can they access cloud resources?
Can they reach OT?
Can they establish command and control?
Can defenders detect lateral movement?
Can compromised tokens be revoked?
Those questions provide a far more realistic picture of resilience.
The Best Defense Is Layered Failure
A mature security architecture assumes that individual controls will eventually fail.
The endpoint may miss something.
The firewall may allow something.
A credential may be stolen.
A user may click a malicious link.
A cloud identity may be compromised.
The important question is what happens next.
If multiple independent controls can detect, contain, or limit the attack, the organization can survive the failure of any individual defense.
Organization B Was Not “Secure”
This distinction is essential.
CISA did not demonstrate that Organization B was immune to compromise.
The red team still discovered major weaknesses after the assessment moved into the assume-breach phase.
Organization
That is a more realistic definition of cybersecurity maturity than claiming that an organization has eliminated every vulnerability.
The Biggest Enemy May Be Complacency
A dangerous security environment is not necessarily one with the largest number of vulnerabilities.
It can be an environment where teams believe their existing tools guarantee protection.
CISA’s report challenges that assumption.
A tool that produces an alert nobody investigates is not enough.
A privileged account nobody reviews is not enough.
A cloud credential nobody rotates is not enough.
A segmentation policy nobody tests is not enough.
Security must function in practice, not simply exist on paper.
Organizations Should Measure Containment, Not Just Detection
Security metrics often emphasize how quickly an alert was generated.
But the more important measurement may be how quickly defenders contained the threat.
A mature SOC should track metrics such as:
Time to detect.
Time to triage.
Time to isolate.
Time to revoke compromised access.
Time to identify affected identities.
Time to determine scope.
Time to restore normal operations.
These measurements reveal whether a security organization can actually fight an incident.
The Future SOC Will Be More Integrated
The traditional separation between endpoint security, network security, cloud security, identity security, and OT security is becoming increasingly difficult to maintain.
Modern attacks move across all of those layers.
The future SOC will therefore need unified visibility across identities, devices, applications, networks, cloud services, and operational environments.
The organizations that achieve that integration will have a major advantage over attackers who rely on gaps between teams.
CISA’s Message Is Ultimately Simple
The most powerful conclusion from the assessment is also the simplest:
Security technology does not defend an organization by itself.
People use the technology.
Processes give it meaning.
Policies determine what happens next.
Authority enables action.
Training determines whether analysts recognize the threat.
And architecture determines how far an attacker can travel when prevention fails.
That is why two organizations can face essentially the same attack and experience completely different outcomes.
Deep Analysis: Defensive Commands and Practical Checks
Check Machine Account Quota
Use a read-only domain configuration check to identify the current Machine Account Quota:
Get-ADDomain | Select-Object DNSRoot, 'ms-DS-MachineAccountQuota'
Review the result against your
Inventory AD CS Templates
Begin certificate-template auditing with:
certutil -CATemplates
Prioritize templates that permit authentication, have broad enrollment permissions, or allow identities to be specified in ways inconsistent with the organization’s certificate policy.
Review Service Accounts
List Active Directory service accounts and review their privileges:
Get-ADUser -Filter {ServicePrincipalName -like ""} `
-Properties Enabled,LastLogonDate,PasswordLastSet,ServicePrincipalName |
Select-Object SamAccountName,Enabled,LastLogonDate,PasswordLastSet,ServicePrincipalName
The purpose is defensive inventory and privilege review, not credential extraction.
Audit SCCM Configuration Storage
Identify configuration files associated with management infrastructure:
Get-ChildItem -Path C:\ -Recurse -File <code>-Include .config,.xml,.ini,.json</code> -ErrorAction SilentlyContinue |
Select-Object FullName
Review discovered files for accidentally stored secrets through approved administrative procedures.
Inventory Entra ID Service Principals
Use Microsoft Graph PowerShell to establish application visibility:
Get-MgServicePrincipal -All | Select-Object DisplayName,AppId,Id,AccountEnabled
Then identify applications that possess broad permissions or have no clear business owner.
Review AWS Key Age
For known AWS IAM users, inspect access-key metadata:
aws iam list-access-keys --user-name USERNAME
Long-lived keys should be investigated, rotated, or replaced with temporary credentials and role-based access where appropriate.
Test Token Revocation Procedures
Organizations should maintain a documented process for identifying and revoking compromised cloud sessions.
The test should answer:
Who can revoke a compromised token?
Which identity is affected?
Which applications trust that identity?
How quickly can access be revoked?
How is the revocation verified?
What happens if the attacker already has another valid session?
These questions should be answered before an emergency.
Test Alert Escalation
A controlled red-team or purple-team exercise should verify that a high-confidence alert produces an actual response.
The test should establish:
Detection → Analyst triage → Asset ownership → Escalation → Isolation → Investigation
If the process stops because nobody knows who owns the affected system, the organization has discovered a serious operational weakness.
Test OT Egress Restrictions
For critical infrastructure environments, defenders should validate that systems inside OT security zones cannot establish unauthorized outbound connections.
The objective is to confirm that segmentation and egress policies work as designed without disrupting legitimate industrial operations.
Organization
Reduce False Positives Continuously
SOC teams should maintain a formal process for recurring false positives.
Each recurring alert should be evaluated:
Is the activity legitimate?
Can the detection be tuned?
Can a baseline be established?
Should the alert severity change?
Does the alert require enrichment?
Who owns the resulting investigation?
The goal is not to eliminate alerts.
The goal is to eliminate meaningless alerts.
Build a Shared Security Picture
Security teams should be able to correlate:
Endpoint + Identity + Network + Cloud + Application + OT
An isolated alert may look harmless.
The same alert correlated with a new privileged login, unusual token activity, lateral movement, and suspicious cloud access may clearly indicate an intrusion.
Context transforms detection.

Prediction
(+1) Faster Detection Will Become the Bigger Security Metric
Organizations are likely to place greater emphasis on mean time to detect and mean time to contain rather than simply counting security products or vulnerabilities.
(+1) Identity Security Will Receive More Investment
The combination of Active Directory, certificate services, cloud identities, service accounts, application permissions, and authentication tokens will increasingly be treated as one interconnected security problem.
(+1) Assume-Breach Exercises Will Become More Common
More critical infrastructure organizations are likely to test what happens after an attacker obtains legitimate access instead of focusing exclusively on perimeter prevention.
(+1) SOC Automation Will Focus on Reducing Noise
Security teams will increasingly use automation and behavioral analytics to suppress repetitive false positives while elevating high-confidence identity and lateral-movement signals.
(+1) OT Segmentation Will Become a Strategic Priority
The inability of an attacker to freely move from IT infrastructure into operational technology can dramatically reduce the consequences of a compromise, making segmentation and controlled egress increasingly important.
(-1) Legacy Service Accounts Will Remain a Major Weakness
Organizations that continue to maintain highly privileged service accounts with static credentials and weak configuration controls will remain exposed to attack chains similar to those demonstrated by CISA.
(-1) Alert Fatigue Will Continue to Undermine Understaffed SOCs
Without sustained tuning, ownership, training, and clear escalation procedures, even advanced detection platforms can become overwhelmed by normal business activity.
(-1) Hybrid Cloud Environments Will Continue Expanding the Attack Surface
As organizations connect traditional Active Directory infrastructure with cloud identities and applications, attackers will have more opportunities to move between environments when permissions and authentication controls are poorly managed.
The Larger Prediction
The strongest organizations will not necessarily be those that prevent every intrusion.
They will be the organizations that detect compromise early, contain it quickly, revoke the attacker’s access, limit lateral movement, protect critical systems through segmentation, and recover without allowing a technical incident to become an operational disaster.
CISA’s “Tale of Two SOCs” is therefore more than a comparison of two red team exercises. It is a warning that cybersecurity maturity is ultimately measured not by how many defensive tools an organization owns, but by how effectively those tools, people, processes, and architectural controls work together when an attacker gets through.
