Modern Cloud Attack Paths & Preventive Design Patterns

Privilege Escalation Patterns

Once inside, an attacker's primary goal is to escalate their privileges. There are several common patterns for this in the cloud. Abusing the instance metadata service is a classic technique for stealing credentials. Lateral movement via the IAM passRole permission allows an attacker to assign powerful roles to resources they control. The use of wildcards in IAM policies can create "shadow admins" with far more power than intended. Finally, the exploitation of mis-scoped service accounts can provide a pathway to sensitive data and services. Understanding these patterns, as detailed in our [Identity-First Security guide](/resources/blog/identity-first-security), is the first step to defending against them.

• Remove * wildcards in high-sensitivity policies
• Bounded permission sets per workload tier
• Runtime detection: anomalous AssumeRole chaining

Design Patterns That Collapse Blast Radius

Effective cloud security is not just about preventing breaches; it's also about collapsing the blast radius when a breach does occur. Several key design patterns can help achieve this. Enforcing a strict identity boundary between the build and runtime environments prevents a compromise in one from affecting the other. The use of ephemeral credentials and just-in-time elevation limits the window of opportunity for an attacker. Environment partition keys and explicit data classification tags that gate replication can also help to contain the impact of a breach and prevent lateral movement. These concepts are also discussed in our [Zero Trust Whitepaper](/resources/whitepapers/zero-trust-whitepaper).

Misconfiguration Archetypes

Many cloud security incidents are caused by a small number of recurring misconfiguration archetypes. By understanding these archetypes, organizations can implement templated prevention measures. Common examples include logging being disabled on sensitive services, orphaned security groups that provide unintended network access, mis-scoped cross-account trust relationships, and unrotated machine identities. By automating the detection and remediation of these common misconfigurations, organizations can significantly improve their security posture. This is a core principle of our [Cloud Security Integration services](/resources/services/cloud-security-integration).

• Automate drift detection for logging config
• Centralize machine identity issuance with TTL enforcement
• Continuous review of cross-account trust relationships

Attack Path Mapping Cadence

In a dynamic cloud environment, a quarterly attack path mapping exercise is no longer sufficient; it quickly becomes stale. A more effective approach is to adopt a lightweight monthly diff process. This involves identifying new services, new roles, and new external principals that have been added to the environment. By using graph queries to surface privilege escalation sequences that are less than three hops long, security teams can proactively identify and close the most dangerous attack paths before they can be exploited.

Telemetry Priorities

Not all telemetry is created equal. To maximize signal and minimize noise, security teams should focus their collection efforts on identity boundary transitions and control plane mutations. This includes role assumption events, policy attachments, key creation, and edits to routes, tables, and security groups. These are the high-value events that are most likely to indicate a security incident. High-cardinality data-plane logs can be collected later, once a strong baseline of control plane coverage has been established. This is a key part of our [Detection Engineering Playbook](/resources/blog/detection-engineering-playbook).

• Centralize role assumption logging with session tagging
• Normalize resource ARNs for fast path queries
• Track newly public resources diff daily
• Alert on wildcard policy introduction to privileged roles

Chaos & Validation

The only way to know if your security controls are truly effective is to test them. This is where chaos and validation come in. By intentionally injecting controlled failures—such as removing a least-privilege boundary or introducing a benign misconfiguration in a sandbox environment—security teams can validate their detection and response pipeline speed. This proactive approach to testing helps to identify weaknesses in the security posture before they can be exploited by an attacker.

• Automated diff PR gate for IAM changes
• Monthly misconfiguration game days
• Time-to-detect metric for injected risky policy
• Drift dashboard ownership rotation

Benchmark & Research Signals

External reports continue to surface identity plane abuse and rapid exploitation of exposed control plane permissions. Align monthly attack path mapping outputs with published breakout time benchmarks (e.g., avg eCrime breakout ~48m) to articulate remaining gap between internal detection latency and adversary operational tempo.
