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

Chain of custody is critical in legal contexts as it documents the seizure, custody, control, transfer, analysis, and disposition of evidence. If the chain of custody is broken, it means there is a possibility that the evidence could have been tampered with or compromised, which can lead to it being deemed inadmissible in court.

A protocol analyzer, such as Wireshark, is a tool used to capture and analyze network traffic. It allows security administrators to inspect individual packets, understand the traffic flow, and identify any unusual patterns or issues that may be impacting performance, such as high latency or unusual volume of traffic on a specific port.

A non-disclosure agreement (NDA) is crucial when external parties are provided access to sensitive company devices or information. The absence of an NDA poses a risk that confidential information could be disclosed by the service provider. Therefore, ensuring an NDA is in place with the company that supports sensitive devices would be a key risk identified in the contract.
