The control mechanism that is used to detect the unauthorized modification of key configuration settings isfile integrity. File integrity is the property of ensuring that files are not altered or corrupted by unauthorized users or processes. File integrity can be monitored by using tools that compare the current state of files with a baseline or checksum and alert on any changes.

An example of an attack attribute of an advanced persistent threat (APT) that is designed to remove data from systems and networks is anexfiltration attack vector. An exfiltration attack vector is a method or channel that an APT uses to transfer data from a compromised system or network to an external location. Examples of exfiltration attack vectors include email, FTP, DNS, HTTP, or covert channels.

A limitation of intrusion detection systems (IDS) is that they cannot detectapplication-level vulnerabilities. An IDS is a tool that monitors network traffic or system activity and alerts on any suspicious or malicious events. However, an IDS cannot analyze the logic or functionality of applications and identify vulnerabilities such as SQL injection, cross-site scripting, or broken authentication.

The BEST response to an IT manager's statement that the risk associated with the use of mobile devices in an organizational setting is the same as for any other device is thatreplication of privileged access and the greater likelihood of physical loss increases risk levels. Mobile devices pose unique risks to an organization due to their portability, connectivity, and functionality. Mobile devices may store or access sensitive data or systems that require privileged access, which can be compromised if the device is lost, stolen, or hacked. Mobile devices also have a higher chance of being misplaced or taken by unauthorized parties than other devices.

The MOST serious consequence of mobile device loss or theft is thecompromise of transient data. Transient data is data that is temporarily stored or processed on a mobile device, such as cached data, cookies, browsing history, passwords, or session tokens. Transient data can reveal sensitive information about the user or the organization and can be exploited by attackers to gain access to other systems or networks.

The EASIEST thing for a malicious attacker to detect is thesusceptibility to reverse engineering. Reverse engineering is the process of analyzing the code or functionality of an application to understand its structure, logic, or design. Reverse engineering can be used by attackers to discover vulnerabilities, bypass security mechanisms, or modify the application's behavior. Mobile applications are often susceptible to reverse engineering because they are distributed in binary form and can be easily decompiled or disassembled.

In cloud computing, the type of hosting that is MOST appropriate for a large organization that wants greater control over the environment isprivate hosting. Private hosting is a type of cloud service model where the cloud infrastructure is dedicated to a single organization and hosted either on-premise or off-premise by a third-party provider. Private hosting offers more control over the security, performance, customization, and compliance of the cloud environment than other types of hosting.

The FIRST thing that an IS auditor should do to ensure cyber security-related legal and regulatory requirements are followed by an organization is to determine if the cybersecurity program is mapped to relevant legal and regulatory requirements. This is because mapping the cybersecurity program to relevant legal and regulatory requirements helps to ensure that the organization has identified and addressed all the applicable laws and regulations that affect its cybersecurity posture, such as data protection, privacy, breach notification, etc. Mapping the cybersecurity program to relevant legal and regulatory requirements also helps to evaluate the alignment and compliance of the organization's cybersecurity policies, procedures, controls, and practices with the legal and regulatory requirements. The other options are not the first thing that an IS auditor should do to ensure cyber security-related legal and regulatory requirements are followed by an organization, but rather follow after determining if the cybersecurity program is mapped to relevant legal and regulatory requirements, such as reviewing the most recent legal and regulatory audit report (B), determining if there is a formal process to review changes in legal and regulatory requirements C, or obtaining a list of relevant legal and regulatory requirements (D).

A feature of an intrusion detection system (IDS) is automated response. This is because an IDS is a system that monitors network or system activities for malicious or anomalous behavior, and alerts or reports on any detected incidents. An IDS can also perform automated response actions, such as blocking traffic, terminating sessions, or sending notifications, to contain or mitigate the incidents. The other options are not features of an IDS, but rather different concepts or techniques that are related to intrusion detection or prevention, such as intrusion prevention (A), interface with firewalls C, or back doors into applications (D).
