What is a primary advantage of dial-up access control?

A primary advantage of dial-up access control is that it generally comes with far fewer compliance requirements compared to higher-speed connectivity solutions like broadband. Dial-up access involves a simpler and often less complex infrastructure, which can lead to fewer regulations and standards to adhere to under frameworks like NERC's Critical Infrastructure Protection. Organizations using dial-up may find it easier to manage their compliance obligations because the technology is straightforward, and the risks can be more easily assessed and mitigated.

In contrast, options that suggest high-speed connectivity or real-time data transmission imply a more complex setup that often necessitates stricter compliance due to the increased data flow and the potential for significant impacts on the infrastructure if security is breached. Similarly, ease of use can vary significantly among users, especially with dial-up systems that may be slower and less user-friendly compared to modern solutions. Ultimately, the fewer compliance requirements associated with dial-up can simplify the security management process, making it easier for organizations to focus on maintaining their security posture without the burdens of extensive regulation.
