The GREATEST advantage of using a virtual private network (VPN) over dedicated circuits and dial-in servers is that it is more cost effective. This is because a VPN is a technology that creates a secure and encrypted connection between a client and a server over an existing public network, such as the Internet. A VPN reduces the cost of establishing and maintaining a secure communication channel, as it does not require any additional hardware, software, or infrastructure, unlike dedicated circuits and dial-in servers, which require dedicated lines, modems, routers, switches, etc. The other options are not the greatest advantage of using a VPN over dedicated circuits and dial-in servers, because they either involve security (A), reliability (B), or speed C aspects that may not be significantly different or better than dedicated circuits and dial-in servers.

The best practice to prevent misuse of administrative privileges is to have administrators use a separate non-privileged account for routine tasks that do not require administrative rights. This reduces the risk of accidental changes or security breaches that could occur if the administrator’s highly privileged account were compromised or misused during daily operations.

References = This control measure is aligned with the principle of least privilege and is commonly recommended in cybersecurity frameworks. While I cannot cite the Cybersecurity Audit Manual directly, similar guidelines are often included in cybersecurity literature and standards, including those from ISACA1. For specific references, please consult the ISACA Cybersecurity Audit resources.

 Heuristic-based anti-malware is designed to detect new, previously unknown viruses and exploits by looking for known suspicious behavior patterns or anomalies. Unlike signature-based anti-malware, which relies on a database of known malware signatures, heuristic analysis can identify new threats without prior knowledge of the specific malware, making it more effective against unknown malware.

References: The effectiveness of heuristic-based anti-malware is supported by cybersecurity resources that highlight its ability to catch and block new and emerging threats before they can cause harm, as well as its capability to reduce false positives by evaluating the behavior of a file or program1. Additionally, heuristic analysis is recognized for its proactive threat detection, offering protection against malware that has yet to be discovered2.
