What is one method to secure remote access to corporate networks?

A Virtual Private Network (VPN) connection is a widely accepted method to secure remote access to corporate networks. VPNs work by creating an encrypted tunnel between the user's device and the corporate network, ensuring that any data transmitted over the internet is secure and protected from potential eavesdroppers. This encryption safeguards sensitive information from interception, making it more difficult for unauthorized users to access or monitor the data being communicated.

In addition to encryption, VPNs also often provide authentication mechanisms to verify the identity of users before granting access to the network. This adds an extra layer of security, ensuring that only authorized personnel can connect to the corporate resources.

In contrast, using public Wi-Fi connections can expose corporate data to significant risks, as such networks are often unsecured and can be easily exploited by attackers. Email communication may not provide enough security on its own for remote access, as it does not create a secure tunnel or encrypt all types of data effectively. Direct server access lacks the security measures that a VPN offers, as it generally does not employ encryption or proper authentication, making the connection vulnerable to attacks. Thus, a VPN stands out as a robust solution for enabling secure remote access to corporate networks.
