Cloud Security Assessment (CSA)

Understand the risks to which your Cloud environment is exposed

Are you ready to face the cloud security challenge?


A key enabler of digital transformation for an organization is their cloud computing capabilities. Any cloud footprint transforms business, private and governmental organizations, enabling new levels of speed, agility and access. However, like any emerging technology, the cloud computing requires heightened thinking from business leaders and even traditional IT professionals, to address the evolving set of security threats spawning from Cloud computing infrastructure and its rapid adoption and use.

To address the cloud security challenges, at Atos, we propose an approach in 3 steps: assess, protect, detect & respond. To protect your cloud environments, you must first identify the ‘what’, the associated risks and requirements.

The aim of cloud security assessment


The cloud environment is constantly changing and it makes it difficult to rapidly detect and respond to threats. A cloud security assessment (CSA) can help you identify and mitigate security risks in cloud computing. It covers the 11 major security threats identified by the Cloud Security Alliance:

  1. Data breaches
  2. Misconfiguration and Inadequate Change Control
  3. Lack of Cloud Security Architecture and Strategy
  4. Insufficient Identity, Credential, Access and Key Management
  5. Account hijacking
  6. Insider Threat
  7. Insecure Interfaces and APIs
  8. Weak Control Plane
  9. Metastructure and Applistructure Failures
  10. Limited Cloud Usage Visibility
  11. Abuse and Nefarious Use of Cloud Services

Manage risks in the cloud

The Atos Cloud Security Assessment (CSA) is a service to assess the security and risk posture of public clouds in use by clients. The CSA is a tightly-scoped service in terms of activities and pricing. Tight scoping provides cost predictability while still assuring high-quality results based on a carefully design framework.

Current state assessment

Assess your infrastructure and application landscape on 5 dimensions (business and IT alignement, IT org., Agile and DevOps maturity, cloud awareness, change readiness).

Application assessment

Define your cloud fitness and analyze your applications’ classification, future positioning and code.

Cloud security enhancement

Establish the cloud security program with key services such as cloud security posture management (CSPM), data leakage prevention, endpoint detection & response.


The current cloud environments offered are Google Cloud Platform (GCP), Microsoft Azure platform and Amazon Web Services (AWS). The CSA results will enable the clients to address immediate issues, plan for long-term cloud security and risk management, and confidently adopt emerging technologies that are enabled through cloud computing.

Are you ready?


A Cloud Security Assessment can help you answer the following questions and can guide you on the steps to take:

  • Do you know where your data is stored and what type of data it is (e.g. personal data)?
  • What are the security and privacy risks inherent to your Cloud usage?
  • What is your visibility on Shadow IT?
  • Are your current security controls providing sufficient visibility, context and insight to the threat facing your sensitive data across the hybrid cloud?
  • Taking account of GDPR, NIS and other regulations, are you investing in the right places to achieve the correct levels of security for how your sensitive data should be protected across the hybrid cloud?
