Answer: A
Explanation:
Implementing centralized log management with access controls, encryption, and regular integrity checks is the most effective control for ensuring that system logs are protected from tampering and provide accurate records for auditing. System logs are critical for monitoring activities, detecting incidents, investigating breaches, and supporting regulatory compliance. If logs are not properly secured, they can be modified or deleted by unauthorized personnel, compromising their reliability and undermining audit and forensic efforts. Centralized log management consolidates logs from multiple systems and applications into a single, secure repository, reducing the risk of data loss, inconsistent logging practices, or localized tampering. Access controls restrict who can view, modify, or delete logs, ensuring that only authorized personnel have appropriate permissions. These controls enforce the principle of least privilege, which minimizes the risk of insider misuse or accidental deletion. Encryption protects logs both in transit and at rest, ensuring that unauthorized individuals cannot read or alter the contents, maintaining confidentiality and integrity. Regular integrity checks, such as hashing and checksum validation, verify that logs have not been modified, providing further assurance of reliability and completeness. This integrated approach provides preventive assurance by securing logs from unauthorized access and tampering, and detective assurance by monitoring access and validating integrity. Auditors can review centralized log management configurations, access control policies, encryption implementations, and integrity check records to confirm compliance with organizational standards and regulatory requirements such as ISO 27001, PCI DSS, SOX, HIPAA, and NIST guidelines.

A) Implementing multi-factor authentication, VPNs, access controls, logging, and monitoring of remote sessions
B) Monitoring network bandwidth usage
C) Performing endpoint antivirus scans
D) Conducting annual security awareness training
Answer: A
Explanation:
Implementing multi-factor authentication, VPNs, access controls, logging, and monitoring of remote sessions is the most effective control for ensuring that remote access to corporate systems is secure and monitored. Remote access allows employees, contractors, and partners to connect to corporate systems from outside the organizational network, increasing operational flexibility but also introducing significant security risks, including unauthorized access, data leakage, and exposure to malware. Multi-factor authentication (MFA) strengthens security by requiring users to provide two or more independent credentials, typically something they know, something they have, or something they are, making it much more difficult for attackers to gain access even if passwords are compromised. Virtual private networks (VPNs) encrypt data traffic between remote devices and corporate systems, ensuring cthe onfidentiality and integrity of communications and protecting sensitive information from interception over public networks. Access controls define who can connect remotely and what resources they can access, enforcing the principle of least privilege and reducing the risk of unauthorized activities. Logging and monitoring of remote sessions provide visibility into remote access activities, including successful and failed login attempts, duration of sessions, and specific actions taken. These records support auditing, anomaly detection, and forensic investigations in case of incidents. This integrated approach provides preventive assurance by securing authentication, access, and communications, and detective assurance by tracking, logging, and monitoring activity. Auditors can review authentication methods, VPN configurations, access control policies, session logs, and monitoring reports to confirm that remote access policies are enforced and aligned with organizational standards and regulatory requirements such as ISO 27001, NIST, HIPAA, and PCI DSS. Effective remote access management reduces the risk of unauthorized access, data breaches, insider threats, regulatory violations, and operational disruptions. Continuous monitoring, periodic reviews, and testing of remote access controls ensure they remain effective as threats, technologies, and business requirements evolve.
