According to the CIS AWS (Center for Internet Security AWS) benchmarks, unauthorized API calls should be closely monitored because they indicate potential security threats or malicious activity within the AWS environment. Monitoring unauthorized API calls helps detect unauthorized access, misconfigurations, or attempts to exploit cloud resources. It's a key part of maintaining a secure AWS environment and helps ensure compliance with security best practices.

Regular file backups are important but not specifically a focus of the CIS AWS benchmarks. Data encryption at rest is a security best practice but monitoring unauthorized API calls directly addresses access control and security within the environment. Successful login attempts are important but monitoring failed login attempts (as opposed to successful ones) is generally a better practice for identifying suspicious activity.

While AI improves threat detection, it also introduces risks as attackers can use it to develop advanced attack methods. Organizations must balance these risks. Reference: [CCSK Study Guide, Domain 12 - AI and Security]

Load balancing is a key resilience strategy in both traditional and cloud environments. It evenly distributes network or application traffic across multiple servers to ensure no single server becomes a point of failure or overloaded, thereby improving system availability, performance, and fault tolerance.

In cloud infrastructure, load balancers may work at various OSI layers (Layer 4 or Layer 7) and are often integrated into cloud platforms as managed services (e.g., AWS Elastic Load Balancer or Azure Load Balancer). They play a critical role in mitigating risks like traffic spikes, system failure, or regional outages.

This technique is described inDomain 7: Infrastructure Securityof the CCSK guidance, which highlights tools like load balancing, redundant systems, and failover mechanisms to support cloud resilience and availability.

Aligning CSP policies with security and regulatory objectives is essential for ensuring compliance and robust security measures. Reference: [Security Guidance v5, Domain 3 - Risk, Compliance, and Governance]
