Which of the following is a required action for maintaining security in any business?

Regularly reviewing security protocols is a critical action for maintaining security in any business because it helps ensure that security measures remain effective in the face of evolving threats and changing technology. As cybersecurity threats advance and new vulnerabilities are discovered, businesses must assess their existing policies and controls to identify potential gaps. This proactive approach can involve updating software, revising incident response plans, ensuring compliance with regulatory requirements, and adapting to industry best practices.

By continuously reviewing and updating security protocols, organizations can better protect sensitive data and mitigate the risks of potential breaches. This action demonstrates a commitment to security and helps to foster a culture of vigilance throughout the organization. In contrast to this, ignoring aspects like outdated technology, avoiding personnel training, or reducing security budgets would undermine overall security efforts and increase the likelihood of successful cyber attacks.
