Security Posture

Suggest Edits

Introduction

Continuous checks on the security posture of your cloud accounts are essential to maintaining a secure cloud environment. The Security Posture feature in the platform provides information about threats, vulnerabilities, and guardrail findings across your cloud accounts. The summary section provides the consolidated counts across all accounts, and the grid section provides account-specific details.

  • Threats: These are consolidated security alerts and threats that originate from cloud-native threat management services such as AWS GuardDuty and Azure Security Center (Standard).
  • Vulnerabilities: These are the result of vulnerability assessments of the workloads running in your cloud environments, which are an essential part of cyber security programs. These vulnerabilities are fetched from cloud-native services including AWS Inspector and Azure Security Center across all your cloud accounts.
  • Guardrail Findings: These are policy violations identified in your cloud accounts based on the guardrails configured for those accounts. These guardrails are typically comprised of industry standards and best practices, including those recommended by AWS and Azure. Any violations to such checks are listed here so that the appropriate actions can be taken.

📘

Note:

To ensure that CoreStack can fetch threats and vulnerabilities from native cloud services, it’s required that the respective cloud services are enabled in the preferred regions.

Please note that these services are associated with some cost, but they do go a long way in ensuring security and can help save on costs incurred in case of a security breach.
