SY0-701 Practice Test

Explanation: Deploying a Security Information and Event Management (SIEM) solution allows for efficient log aggregation, correlation, and analysis across an organization’s infrastructure, providing real-time security insights.

Explanation: Reviewing the source code of an application to identify misconfigurations and vulnerabilities is best described as static analysis. Static analysis involves examining the code without executing the program. It focuses on finding potential security issues, coding errors, and vulnerabilities by analyzing the code itself.
Static analysis: Analyzes the source code or compiled code for vulnerabilities without executing the program.
Dynamic analysis: Involves testing and evaluating the program while it is running to identify vulnerabilities.
Gap analysis: Identifies differences between the current state and desired state, often used for compliance or process improvement.
Impact analysis: Assesses the potential effects of changes in a system or process.

Explanation: Jailbreaking is the process of removing the restrictions imposed by the manufacturer or carrier on a mobile device, such as an iPhone or iPad. Jailbreaking allows users to install unauthorized applications, modify system settings, and access root privileges. However, jailbreaking also exposes the device to potential security risks, such as malware, spyware, unauthorized access, data loss, and voided warranty. Therefore, an organization may prohibit employees from jailbreaking their mobile devices to prevent these vulnerabilities and protect the corporate data and network.

Explanation: A VPN is a virtual private network that creates a secure tunnel between two or more devices over a public network. A VPN can encrypt and authenticate the data, as well as hide the IP addresses and locations of the devices. A jump server is a server that acts as an intermediary between a user and a target server, such as a production server. A jump server can provide an additional layer of security and access control, as well as logging and auditing capabilities. A firewall is a device or software that filters and blocks unwanted network traffic based on predefined rules. A firewall can protect the internal network from external threats and limit the exposure of sensitive services and ports. A security analyst should recommend setting up a VPN and placing the jump server inside the firewall to improve the security of the remote desktop access to the production network. This way, the remote desktop service will not be exposed to the public network, and only authorized users with VPN credentials can access the jump server and then the production server.

Explanation: Firmware is a type of software that is embedded in hardware devices, such as BIOS, routers, printers, or cameras. Firmware controls the basic functions and operations of the device, and can be updated or patched to fix bugs, improve performance, or enhance security. Firmware vulnerabilities are flaws or weaknesses in the firmware code that can be exploited by attackers to gain unauthorized access, modify settings, or cause damage to the device or the network. A BIOS update is a patch that addresses a firmware vulnerability in the basic input/output system of a computer, which is responsible for booting the operating system and managing the communication between the hardware and the software. The other options are not types of vulnerabilities, but rather categories of software or technology.
