Helping Hand Questions for SY0-601

A generator and a UPS (uninterruptible power supply) are low-cost solutions that can provide backup power to an organization in case of a power outage. A generator is a device that converts mechanical energy into electrical energy, while a UPS is a device that provides battery power to a system when the main power source fails. A generator and a UPS can help the organization to maintain its operations and prevent data loss during a power outage.

A web application firewall (WAF) is a security solution that monitors and filters the traffic between a web application and the internet. It can prevent code injection attacks by blocking malicious requests that contain code snippets or commands that could compromise the web application. A WAF can also enforce input validation rules and sanitize user inputs to prevent code injection. References: CompTIA Security+ SY0-601 Certification Study Guide, Chapter 4: Implementing Secure Network Designs, page 194; 5 ways to prevent code injection in JavaScript and Node.js

Geolocation and time-of-day restrictions would be best to mitigate the CEO’s concerns about staff members working from high-risk countries while on holiday or outsourcing work to a third-party organization in another country. Geolocation is a technique that involves determining the physical location of a device or user based on its IP address, GPS coordinates, Wi-Fi signals, or other indicators. Time-of-day restrictions are policies that limit the access or usage of resources based on the time of day or week. Geolocation and time-of-day restrictions can help to enforce access control rules, prevent unauthorized access, detect anomalous behavior, and comply with regulations. References:

HSMaas stands for Hardware Security Module as a Service, which is a cloud-based service that provides secure and scalable key management and cryptographic operations for data encryption and decryption. HSMaas allows the organization to use its own keys or generate new ones, and to control and manage them centrally regardless of where the data is stored or processed. HSMaas also reduces the latency and complexity of managing multiple encryption keys across different cloud providers, as well as the cost and maintenance of deploying physical HSM devices.

A. Trusted Platform Module. This is not the correct answer, because a Trusted Platform Module (TPM) is a hardware chip that provides secure storage and generation of cryptographic keys on a device, such as a laptop or a server. A TPM does not offer a cloud-based solution for key management and encryption across multiple cloud providers.

B. laaS. This is not the correct answer, because laaS stands for Infrastructure as a Service, which is a cloud computing model that provides virtualized computing resources, such as servers, storage, and networks, over the internet. laaS does not provide a specific solution for key management and encryption across multiple cloud providers.

C. HSMaas. This is the correct answer, because HSMaas stands for Hardware Security Module as a Service, which is a cloud-based service that provides secure and scalable key management and cryptographic operations for data encryption and decryption across multiple cloud providers.

D. PaaS. This is not the correct answer, because PaaS stands for Platform as a Service, which is a cloud computing model that provides a platform for developing and deploying applications over the internet. PaaS does not provide a specific solution for key management and encryption across multiple cloud providers.
