Case study
AWS Attack Path Analysis and Risk Prioritization
Evaluated how exposure, permissions, and trust relationships could combine, then sequenced remediation by business impact.

Context
The organization operated a rapidly evolving AWS environment supporting production web services, APIs, internal tooling, and CI/CD infrastructure. While standard security checks existed, cloud security visibility was largely control- and checklist-driven, making it difficult to understand how individual misconfigurations combined into real attack paths.
My objective was to move cloud security from static misconfiguration reporting to risk-based attack path analysis, enabling teams to focus on what actually mattered.
Problem Statement
Traditional cloud security approaches exposed several limitations:
- Large volumes of isolated misconfiguration findings
- Difficulty prioritizing which issues posed real exploitation risk
- Limited understanding of cross-service attack chains
- Engineering fatigue caused by low-signal alerts
- Security discussions focused on “best practices” rather than business risk
This resulted in security effort being spread thin and high-impact risks competing with low-value findings for attention.
My Role and Ownership
I owned the design, execution, and prioritization of cloud security analysis across AWS, including:
- Continuous assessment of AWS configurations
- Identification of realistic attack paths, not just single-point failures
- Risk prioritization based on exploitability and blast radius
- Translating technical findings into actionable remediation for engineering teams
- Advising leadership on cloud risk posture and trade-offs
This role required both deep AWS knowledge and attacker-oriented thinking.
Strategy and Methodology
1. From Misconfigurations to Attack Paths
Instead of treating findings independently, I analyzed how multiple weaknesses could be chained together, for example:
- Overly permissive IAM roles combined with public-facing services
- Weak network segmentation enabling lateral movement
- Insecure CI/CD permissions leading to credential exposure
- Excessive trust relationships between AWS services
The focus shifted from “what is misconfigured” to “how an attacker would progress”.
2. Continuous Cloud Posture Assessment
I implemented continuous posture visibility using CSPM tools (Prowler, ScoutSuite) to:
- Detect deviations from secure baselines
- Track recurring configuration patterns
- Identify control drift over time
Findings were filtered to surface exploitable conditions, not informational gaps.
3. Risk-Based Prioritization Framework
Each attack path was evaluated based on:
- Initial access likelihood (public exposure, credential paths)
- Privilege escalation potential
- Lateral movement opportunities
- Blast radius (data access, production impact)
- Ease of exploitation
This enabled objective prioritization and avoided debates based on theoretical severity.
4. Engineering-Focused Remediation
Rather than delivering raw CSPM output, I:
- Documented attack paths in plain engineering language
- Highlighted why a fix mattered, not just what to fix
- Suggested remediation options with minimal operational impact
- Worked with teams to sequence fixes safely in production
This improved adoption and reduced resistance to cloud security changes.
Impact and Outcomes
- Identified and remediated high-risk attack paths that would not have been prioritized using checklist-based reviews
- Reduced alert fatigue by focusing on exploitable conditions
- Improved engineering understanding of cloud threat models
- Enabled leadership to make informed risk decisions
- Established a repeatable approach for cloud risk prioritization
Cloud security shifted from “fix everything” to “fix what matters first.”
Trade-offs and Lessons Learned
- Not all misconfigurations deserve immediate remediation
- Context and chaining matter more than individual findings
- Cloud security must align with operational realities
- Engineers engage more when risk is explained through attacker perspective
These lessons informed improvements across DevSecOps and compliance efforts.
