Cloud Security protects access to sensitive information and applications across a variety of environments, whether they are public, private or hybrid clouds. It addresses stringent compliance requirements and provides a framework for regulatory adherence, and it protects against data breaches that could damage commercial or personal information.

Understanding which tasks are the responsibility of your CSP and which you take on yourself is crucial for building a resilient cloud security strategy. These tasks typically fall under the umbrella of identity and access management, network controls, security monitoring, encryption, and compliance. These cloud security best practices ensure secure collaboration and remote access for authorized users and safeguard against threats that could impact application availability, integrity, and confidentiality.

IAM enables an organization to deploy security policies for all user and system interactions with cloud apps. It verifies identities through authentication methods like multi-factor authentication and regulates authorization by defining permissions to reduce the risk of unauthorized access. It also manages account provisioning and de-provisioning to revoke access for employees who no longer require it, reducing the risk of insider threats.

Network security aims to secure the cloud infrastructure by deploying perimeter defenses such as firewalls, intrusion detection and prevention systems (IDPS) or virtual private networks (VPNs), guaranteeing isolation through segmentation, and continuously monitoring to detect anomalies. It also identifies and mitigates vulnerabilities in cloud-based apps by performing code reviews, encrypting data at rest or in motion, and updating the application with security patches.
