Offensive Security

Cloud Security Assessment

AWS, Azure and GCP configuration review, IAM analysis and exploitation of misconfigured cloud resources — against CIS Benchmarks and the CSA Cloud Controls Matrix.

Overview

Misconfiguration is the cloud’s number-one risk.

Most cloud breaches come down to misconfiguration and over-permissive access rather than exotic exploits. Public storage, broad IAM roles and exposed management interfaces quietly create serious risk.

We combine configuration review against CIS Benchmarks with hands-on testing of IAM, network controls and exposed services — identifying not just individual misconfigurations but the privilege-escalation paths that chain them together.

What we test

Focus areas of the assessment.

The core areas we examine in a cloud security assessment engagement.

IAM & privilege analysis

Over-permissive roles, policies and escalation paths to higher access.

Storage & data exposure

Public or misconfigured buckets, blobs and databases exposing data.

Network & security-group config

Exposed services, open ports and weak network segmentation.

Logging, monitoring & keys

Gaps in audit logging, monitoring and key/secret management.

CIS benchmark gaps

Configuration drift from hardening baselines across the estate.

Privilege escalation paths

Chained misconfigurations that lead from low to high privilege.

Regulatory drivers

Why this is required

Misconfigured cloud is now a leading cause of breaches and an explicit focus of regulators and frameworks, so benchmarking your environment against CIS and provider best practice is expected for regulated workloads.

RBI / SEBI cloud expectations

Regulated entities must assess and govern the security of cloud deployments, including configuration, identity, data localisation and exit.

ISO/IEC 27001:2022

Cloud services fall within the ISMS scope and its supplier, configuration and access controls.

CIS Benchmarks & CSP best practice

The recognised baselines against which cloud configuration and hardening are assessed.

DPDPA & GDPR

Require security of processing for personal data hosted or processed in the cloud.

How we work

A disciplined testing methodology.

A repeatable, standards-based process that balances depth with operational safety.

Scoping & account intake

Defining in-scope cloud accounts, services and access for review.

Configuration & IAM review

Benchmarking configuration and identity against CIS and best practice.

Identity, network & data analysis

Analysing exposure across identities, network paths and data stores.

Exploitation of misconfigurations

Safely demonstrating impact from real misconfigurations.

Privilege & blast-radius validation

Mapping privilege escalation and the blast radius of a compromise.

Reporting & remediation

FAQ

Common questions

Is this a config review or a penetration test?

Both. We review configuration against CIS Benchmarks and actively test IAM and exposed services to demonstrate real, exploitable impact — not just a checklist of settings.

Do you need access to our cloud account?

Read-only access enables a thorough configuration and IAM review; we can also test from an external attacker’s perspective. We agree the right combination during scoping.

Do you cover multi-cloud environments?

Yes. We assess AWS, Azure and GCP individually and can review how identity and trust span multiple clouds in a single engagement.
