Availability can be protected through the use of:
Answer : 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).
When passwords are tied into key generation, the strength of the encryption algorithm is:
Answer : D
When passwords are used in key generation, they serve as a component of the encryption process. The strength of the encryption algorithm itself is not inherently affected by the use of passwords for key generation. Instead, the security of the encryption relies on the strength and complexity of the password, the key generation process, and the encryption algorithm's resilience to attacks. A strong, complex password can contribute to a robust encryption key, thereby maintaining the intended strength of the encryption algorithm.
When reviewing user management roles, which of the following groups presents the GREATEST risk based on their permissions?
Answer : A
When reviewing user management roles, the group that presents the GREATEST risk based on their permissions is privileged users. This is because privileged users are users who have elevated or special access rights or permissions to systems or resources, such as administrators, superusers, root users, etc. Privileged users present the greatest risk based on their permissions, because they can perform actions or operations that can affect the security, availability, or functionality of systems or resources, such as installing or uninstalling software, modifying or deleting files, granting or revoking access rights, etc. Privileged users can also abuse or misuse their permissions for malicious or unauthorized purposes, such as stealing or leaking sensitive data, sabotaging systems or services, bypassing security controls, etc. The other options are not groups that present the greatest risk based on their permissions, but rather different types of users that may have different levels of access rights or permissions to systems or resources, such as database administrators (B), terminated employees C, or contractors (D).
Which of the following is an objective of public key infrastructure (PKI)?
Answer : B
An objective of public key infrastructure (PKI) is to independently authenticate the validity of the sender's public key. PKI is a system that uses cryptographic keys to secure communications and transactions. PKI involves a trusted third party called a certificate authority (CA) that issues digital certificates that link a public key with an identity. The recipient can use the CA's public key to verify the sender's certificate and public key.
Which of the following is an example of an application security control?
Answer : A
An example of an application security control issecure coding. Secure coding is the practice of developing software applications that follow security principles and standards to prevent or mitigate common vulnerabilities and risks. Secure coding involves applying techniques such as input validation, output encoding, error handling, encryption, and testing.
Which of the following is MOST critical to guiding and managing security activities throughout an organization to ensure objectives are met?
Answer : C
The MOST critical thing to guiding and managing security activities throughout an organization to ensure objectives are met is establishing metrics to measure and monitor security performance. This is because metrics provide quantifiable and objective data that can be used to evaluate the effectiveness and efficiency of security activities, as well as identify gaps and areas for improvement. Metrics also enable communication and reporting of security performance to stakeholders, such as senior management, board members, auditors, regulators, customers, etc. The other options are not as critical as establishing metrics, because they either involve spending money without knowing the return on investment (A), adopting standards without customizing them to fit the organization's context and needs (B), or conducting training without assessing its impact on behavior change (D).
Which control mechanism is used to detect the unauthorized modification of key configuration settings?
Answer : D
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.
