Which of the following is a key aspect of ensuring digital security in Azure?

Implementing Azure Security best practices is crucial for ensuring digital security in the Azure environment. This involves leveraging the built-in security features and services provided by Azure, such as Azure Security Center, Azure Active Directory, and role-based access control. These tools and strategies help protect against unauthorized access, data breaches, and various cybersecurity threats.

By adhering to best practices, organizations can consistently monitor their cloud environments, manage security configurations, conduct threat assessments, and continually improve their security posture based on the latest recommendations. This proactive approach ensures that applications and data hosted in Azure are safeguarded effectively.

Utilizing third-party security solutions can complement Azure's security features but does not solely ensure comprehensive security. Restricting access to on-premises servers only does not take advantage of the flexible and scalable nature of Azure services, and using outdated firewall technologies directly contradicts modern security protocols and best practices, rendering systems vulnerable to current threats.
