What Is Cloud Security?
Cloud Security consists of the strategies and technologies that protect data, applications, and infrastructure hosted in public or private clouds. It includes application, server, and network security solutions that provide visibility into cloud environments, protect against threats, and maintain compliance.
Cloud security is evolving rapidly, driven by a growing threat volume and sophistication. AI-driven attacks, automated reconnaissance, and identity-centric threats are challenging traditional defenses. Security teams need adaptive security that adapts to dynamic infrastructure. This includes software development practices that incorporate security and testing into the SDLC, and unified threat detection with a single Security Graph to reduce blind spots.
Deployment models like Infrastructure-as-a-Service (IaaS) separate management responsibilities between providers and clients. Clients are responsible for securing all layers stacked on top of the operating system, including applications, runtimes, data, and remote access. IaaS clouds require security monitoring that combines threat detection and response, vulnerability management, and context-aware policy controls.
Unsecured API endpoints, misconfigured services, and unmanaged shadow assets are high-risk exposure points for a cloud environment. Unified detection and response capabilities help eliminate blind spots by integrating data from multiple cloud platforms into a single view. They can also identify anomalous behavior and prioritize patching for critical vulnerabilities.
Data protection in the cloud ensures that data remains secure at rest, in transit, and during processing. Solutions include VPNs, Zero Trust networks, and encryption. This helps protect against breaches, downtime, and costly penalties for noncompliance. It also helps retain customer trust and reduce risk to the bottom line.
