CompTIA CAS-004 Dumps Questions Answers

In a SaaS cloud service model, the client is typically responsible for the data, including its security and compliance aspects. The SaaS provider would handle the infrastructure, including physical security and network security, but the client must ensure the data they input into the SaaS application is protected in line with their own security policies and compliance requirements.

Before migrating previously isolated systems to the cloud, it is essential to perform patching and hardening. These systems may have been neglected while isolated, so updating them with the latest security patches and applying hardening measures (such as disabling unnecessary services and implementing strict access controls) is crucial to reduce vulnerabilities. This ensures that the systems are secure before they are exposed to the wider cloud environment. CASP+ emphasizes the importance of securing systems through patch management and hardening before integrating them into more exposed environments like the cloud.

A content delivery network (CDN) is a distributed system of servers that delivers web content to users based on their geographic location, the origin of the content, and the performance of the network. A CDN can help improve the availability and performance of web applications by caching content closer to the users, reducing latency and bandwidth consumption. A CDN can also help mitigate distributed denial-of-service (DDoS) attacks by absorbing or filtering malicious traffic before it reaches the origin servers, reducing the impact on the application availability. Supporting heterogeneous architecture means using different types of hardware, software, or platforms in an IT environment. This can help improve resilience by reducing single points of failure and increasing compatibility, but it does not directly prevent DDoS attacks. Ensuring cloud autoscaling is in place means using cloud services that automatically adjust the amount of resources allocated to an application based on the demand or load. This can help improve scalability and performance by providing more resources when needed, but it does not directly prevent DDoS attacks. Scaling horizontally means adding more servers or nodes to an IT environment to increase its capacity or throughput. This can help improve scalability and performance by distributing the load across multiple servers, but it does not directly prevent DDoS attacks. References: [CompTIA Advanced Security Practitioner (CASP+) Certification Exam Objectives], Domain 2: Enterprise Security Architecture, Objective 2.4: Select controls based on systems security evaluation models
