Isaca Cybersecurity-Audit-Certificate Practice Exam Questions & Answers

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.

Asymmetric algorithms are commonly used to securely distribute symmetric keys. The asymmetric encryption process involves a public key for encryption and a private key for decryption. This method ensures that even if the public key is intercepted, the encrypted data cannot be decrypted without the corresponding private key. Symmetric keys are then used for the bulk encryption of data due to their efficiency in processing large volumes of information.

Reference= The use of asymmetric algorithms for key distribution is a well-established practice in the field of cryptography.It is mentioned in various ISACA resources that asymmetric encryption, such as RSA and ECC, is crucial for secure communications, especially for the initial exchange of symmetric keys, which are then used for encrypting data streams or bulk data123.

An information security procedure that indicates a requirement to sandbox emails means that the emails need to be isolated and tested for malicious content. This is because sandboxing is a technique that creates a virtual or isolated environment, where suspicious or untrusted emails can be executed or analyzed without affecting the rest of the system or network. Sandboxing helps to detect and prevent malware, phishing, or spam attacks that may be embedded in emails, and protect the users and the organization from potential harm. The other options are not what sandboxing emails means, but rather different concepts or techniques that are related to information security, such as encryption and nonrepudiation (A), backup and recovery (B), or firewall and delivery (D).

Availability can be protected through the use of redundancy, backups, and business continuity management. This is because these measures help to ensure that systems, data, and services are accessible and functional at all times, even in the event of a disruption or disaster. The other options are not directly related to protecting availability, but rather focus on enhancing confidentiality (A), integrity C, or awareness (D).

An incremental backup is a type of backup that only copies the files that have changed since the last backup was made. This means that after a full backup, subsequent incremental backups will only include the data that has been altered or newly created since the previous backup, making it a more efficient way to save storage space and reduce backup time.

Reference= While I can't provide direct references from the Cybersecurity Audit Manual, the concept of incremental backups is a standard practice in data management and is covered in various cybersecurity and IT audit resources, including those provided by ISACA1. For a detailed understanding, you may refer to the ISACA Cybersecurity Audit Certificate resources or other ISACA study materials.
