How does information systems security enhance data protection?

The correct choice highlights that information systems security enhances data protection primarily through the implementation of safeguards against unauthorized access. These safeguards are crucial in protecting sensitive data from threats such as hacking, data breaches, and other unauthorized activities that could compromise the integrity and confidentiality of the information stored within the systems.

Effective security measures often include a variety of tools and policies, such as firewalls, encryption, authentication protocols, and access controls. By ensuring that only authorized users can access certain data or systems, organizations can mitigate risks and protect their resources from potential misuse or exposure.

On the other hand, the other options do not align with the purpose of data protection through information systems security. Simplifying user access and reducing security protocols can actually lead to vulnerabilities. Increasing the complexity of data entry tasks does not enhance security; rather, it may lead to user errors which can increase security risks. Limiting access solely to high-level management does not offer comprehensive data protection and could hinder necessary access for employees who need it for their roles. Therefore, safeguarding against unauthorized access is essential in establishing a robust security framework for data protection.
