What is a common use of a Virtual Private Network (VPN)?

A common use of a Virtual Private Network (VPN) is to connect remote users securely to a corporate network. VPNs establish a secure and encrypted connection over the internet, allowing users to access resources in a private network as if they were physically present at the office. This secure tunnel protects sensitive data from potential interception by providing confidentiality and integrity for the information being transmitted.

The need for secure remote access has become increasingly important as organizations embrace flexible work arrangements and remote employees. By using a VPN, organizations can maintain robust security measures, ensuring that remote connections are safe and that corporate data remains private and secure from unauthorized access.

Other options, while relevant to network security, do not accurately represent the primary function of a VPN. For instance, validating device status before network access typically involves other security solutions like Network Access Control (NAC), and filtering traffic between cloud services is often managed by other technologies such as firewalls or cloud security platforms. Additionally, while VPNs can provide some level of protection against DNS attacks by encrypting all internet traffic, their main and common function is facilitating secure remote access to networks.
