Security Posture Assessment & Roadmap

Discover gaps in security best practices, create a timed roadmap to improve security posture.

Customers are concerned about a lack of insight into their security risks, the inability to comprehensively communicate their security posture to senior stakeholders, understand gaps in their security approach, and overcome challenges to accelerating innovation while being secure and compliant.

Security Posture Assessment & Roadmap consulting offering aims to address these challenges. It allows an organization to establish a strategic engagement model to understand and visualize their AWS security posture across various workloads or use cases namely data, application, infrastructure, networking, identity and access management, incident response, and regulatory compliance.

In addition, TCS also engages with customers to assess their existing landing zone set up in order to understand their implemented security controls and identify any deviations in security best practices.

  • How it works
  • The consulting engagement begins with a discovery exercise through a standard questionnaire in order to understand the customer's business objectives on AWS.

    The consulting offer uses TCS' security assessment application which customers register themselves for using their contact details to begin the assessment.

    The application then sends the customer instructions to create a cross-account role in order to perform a scan of their target AWS account using an external third-partner identity.

    The scan generates a report containing metrics on their AWS security posture, namely the presence of elevated IAM permissions and public AWS Lambda functions, any absence of Amazon CloudWatch metrics and alarms to name a few. The application also collects a total of 70+ findings across use cases that include data, application, infrastructure, networking, logging & monitoring, incident response and regulatory compliance. The findings are gaps found in security posture such as presence of elevated IAM privileges, presence of vulnerable AWS Lambda functions, presence of sensitive information in EC2 user data and many more.

    The above findings are stored in customer's S3 bucket in their AWS account in order to ensure there is no storage of customer data.

    Based on the observation and analysis gained so far, security remediations are prescribed and presented in the form of a timed roadmap. This roadmap contains an implementation plan where remediations are categorized into three "win" phases:quick, medium-term, and long-term wins.

    Quick wins contain those security recommendations that are critical but simple to carry out. Medium-term wins include remediations that take more time but are still important. Long-term wins are highly strategic in nature, bringing in governance and optimization, and therefore will take more planning and implementation time.

    At the completion of the consulting engagement, the customer receives a roadmap, including a timeline and the costs involved to increase their security posture.
