What Is Cloud Security?
Cloud Security is a specialized subset of cybersecurity focused on safeguarding data, applications and services from threats in cloud environments. It addresses unique risks like misconfigurations, insecure APIs and shared infrastructure vulnerabilities.
Sensitive data must be protected at rest in public clouds and in transit to prevent unauthorized access or leakage. Encryption and access control tools enable this protection, while identity management solutions (SSO, MFA) limit user privileges. Security information and event management (SIEM) tools deliver visibility into cloud activity and threat detection.
Security teams must also monitor cloud architecture for misconfigurations and vulnerabilities, and be able to quickly respond to in-progress attacks. Threat detection and response solutions support this, including continuous monitoring, alerting, and investigation of attacks, with capabilities for containment and remediation.
Other key areas include governance and compliance, which builds redundancy to ensure systems can be recovered in case of a disruption; and business continuity, which maintains services in the event of an outage or data loss. Additionally, regulatory compliance focuses on meeting organizational or governmental regulations.
As the world continues to move more and more to the cloud, it’s essential to adopt a comprehensive security strategy that covers all aspects of your cloud environment. By deploying best practices and implementing strong security measures, you can protect your organization’s data from cyberattacks, maintain operational resilience and maintain customer trust. To do this, start by understanding your needs:
