01 / Overview
Authorized infrastructure security testing.
Infrastructure Security is a separate operational service. It covers infrastructure exposure, identity paths, endpoint behavior, runtime controls, cloud boundaries, and privilege movement only where the owner has approved scope, timing, targets, and rules of engagement in writing.
OSCP / OSEP is used here as a scope reference for the kind of infrastructure and exploitation discipline involved. It is not a public claim of certification, client authorization, or permission to test. The work is useful only when safety, evidence, communication, remediation, and retest expectations are defined before activity begins.
Infrastructure security work is not one generic scan. OCO runs it as a written, authorized engagement that separates what can be observed, what can be actively validated, what can be stressed, what evidence can be retained, and what must be repaired and retested before the work is closed.
Infrastructure Security Flow
A controlled path for infrastructure, identity, cloud, runtime, and access testing.
03 / Asset inventory
Asset inventory
OCO builds the approved infrastructure map before testing: domains, DNS zones, edge services, cloud accounts, repositories, CI/CD routes, VPN or access gateways, identity providers, endpoints, servers, containers, Kubernetes clusters, databases, storage, backup paths, monitoring systems, and administrative consoles. The work identifies what exists, who owns it, why it is exposed, and what data or operation it supports.
Basic inventory checks for missing ownership, unknown assets, stale routes, exposed admin paths, untracked services, old certificates, unmanaged endpoints, weak backup visibility, and logging gaps. Advanced inventory separates internet-facing assets, internal trust zones, privileged administration paths, production dependencies, non-production exposure, shared-provider risk, and recovery systems that need stronger protection.
04 / External exposure
External exposure
External exposure work reviews the public and partner-facing boundary: DNS records, edge routing, CDN and WAF behavior, TLS posture, open services, remote access points, exposed APIs, admin panels, mail and domain controls, storage URLs, webhook receivers, and non-production environments. The goal is to understand what an outside party can discover or reach before testing deeper paths.
Basic validation confirms whether exposed services are intentional, patched, documented, rate-limited, logged, and behind the expected access layer. Advanced validation can test controlled abuse pressure against routing assumptions, weak segmentation between public and private surfaces, exposed staging services, misrouted callbacks, edge bypass assumptions, and monitoring response to noisy but authorized probes.
05 / Identity
Identity
Identity testing covers users, groups, MFA, SSO, service accounts, API keys, tokens, machine identities, cloud roles, admin roles, break-glass access, onboarding and offboarding, and session behavior. Basic work verifies that expected identity controls exist and are enforced. Advanced work examines chained identity assumptions across cloud, endpoint, repository, CI/CD, runtime, and administration paths.
A realistic identity stress scenario can start from an approved low-privilege test identity and measure whether MFA, conditional access, device posture, token lifetime, role boundaries, service-account limits, and alert escalation prevent the identity from reaching protected administration or sensitive records. The test records what stopped the path and what did not.
06 / Endpoint
Endpoint
Endpoint review examines workstations, servers, management agents, device posture, local administrator use, patching, EDR or antivirus behavior, disk encryption, browser and credential storage, remote-management paths, and developer machines where source code or deployment access may exist. Basic testing checks hygiene. Advanced testing focuses on whether endpoint compromise would become infrastructure compromise.
Controlled endpoint stress testing can validate whether a simulated suspicious process, credential-use pattern, unusual admin action, or approved containment exercise is detected, isolated, escalated, and recovered. The point is not theatrical exploitation; it is proving that endpoint controls, identity controls, logging, and operator response work together.
07 / Cloud/runtime
Cloud/runtime
Cloud and runtime testing covers provider accounts, IAM, projects, subscriptions, VPCs, firewalls, Kubernetes clusters, container registries, secrets, serverless functions, queues, storage, databases, deployment identities, runtime permissions, logs, and backup controls. Basic review confirms configuration hygiene. Advanced review checks trust boundaries between workloads, environments, providers, and deployment systems.
Advanced scenarios can test whether one workload can reach another without approval, whether a deployment identity can touch production data, whether secrets are overexposed, whether a container or job has more permission than required, and whether logs show the path. Stress testing can pressure environment separation and rollback behavior without targeting unrelated production systems.
08 / Network paths
Network paths
Network-path review covers segmentation, routing, firewall rules, ingress and egress, VPN, private links, service discovery, admin ports, internal APIs, database reachability, vendor connections, and monitoring visibility. Basic work confirms that routes match the intended architecture. Advanced work tests whether a reachable path can be chained into a higher-risk operation.
A realistic network stress scenario can validate whether approved test traffic crossing zones is blocked, logged, rate-limited, or escalated, and whether fallback routes or provider links bypass intended controls. OCO records the route, control point, expected behavior, observed behavior, and operational risk without publishing reusable attack instructions.
09 / Privilege paths
Privilege paths
Privilege-path testing follows how access could expand across identity, endpoint, repository, CI/CD, cloud, runtime, database, and administration layers. Basic checks identify excessive permissions and missing separation. Advanced checks model chained control failures: weak role design, overpowered service accounts, deployment identities with production reach, stale administrator paths, and recovery accounts without strong review.
The stress question is whether a low-risk starting point can become a high-risk action before controls stop it. OCO can simulate an approved access chain and measure where it fails: MFA, conditional access, device posture, role policy, runtime permission, network segmentation, privileged approval, alert escalation, or human approval. Each step is evidence-driven and bounded.
10 / Detection
Detection
Detection review checks whether infrastructure activity becomes usable operational evidence: identity logs, endpoint telemetry, cloud audit logs, runtime logs, network events, WAF and edge events, CI/CD logs, admin actions, storage access, backup events, alerts, dashboards, and incident handoff. Basic checks confirm the logs exist. Advanced checks test whether related signals connect into one incident story.
A controlled detection stress test can create an approved sequence of events across identity, endpoint, cloud, runtime, and network layers, then measure alert timing, correlation, severity, owner notification, containment action, evidence quality, and whether the team can explain what happened without manually guessing from unrelated logs.
11 / Stress scenario
Stress scenario
The stress scenario is a controlled, time-boxed exercise that combines approved infrastructure signals into a realistic operating test. It can include a simulated low-privilege identity, a reachable non-production service, a cloud role boundary, an endpoint containment event, a noisy but rate-limited probe, a recovery action, and an alert escalation path. The scenario is designed to test controls together, not to create uncontrolled damage.
The scenario defines start condition, target controls, expected stop points, monitoring expectations, contact path, rollback path, evidence to capture, success criteria, failure criteria, and residual-risk decision. A strong scenario measures whether the system can resist, detect, contain, explain, and recover from realistic pressure across several layers without crossing the authorized boundary.
12 / Remediation
Remediation
Findings are converted into engineering work: reduce access, close exposure, adjust identity policy, harden endpoints, separate privileged operations, tune cloud roles, improve segmentation, protect secrets, add logs, improve alerts, patch systems, change deployment paths, improve backups, and document recovery. Basic remediation closes obvious exposure. Advanced remediation reduces chained risk across layers.
Each fix needs an owner, severity, affected asset, affected control, expected behavior, implementation path, rollback path, operational impact, residual risk, and the exact retest condition. OCO avoids reporting that says only fix the issue; the output must make the engineering and operating change clear enough to execute.
13 / Retest
Retest
Retest verifies that the control holds under the same pressure that produced the finding. It does not only confirm that a configuration value changed. The retest checks the fixed route, identity path, endpoint behavior, cloud permission, network path, detection signal, and recovery behavior that were part of the original evidence.
Closure requires retest evidence, remaining risk, owner acceptance, monitoring proof, rollback notes where relevant, and a clean explanation of what changed. If the same path still works, the finding remains open. If the control holds but creates operational friction, the residual-risk decision is recorded instead of hidden.
14 / Security report
Security report
The final infrastructure security report separates owner-only technical evidence from disclosure-safe summaries. It records authorization, exclusions, tested assets, methods, timeline, findings, affected controls, stress-test behavior, remediation status, retest proof, residual risk, and owner decisions. The report is written so engineering teams can fix issues, operators can understand impact, and leadership can see what risk changed.
Owner-only material can include screenshots, logs, request or event references, configuration evidence, control behavior, and retest artifacts. Public or partner-facing summaries remove exploit steps, credentials, private architecture, sensitive data, client material, and anything that would make the finding easier to reproduce outside the approved scope.
