When maintaining a cloud environment, what should be done to ensure the security of data-in-transit?

Implementing a VPN tunnel for secure communication is a crucial measure to ensure the security of data-in-transit. A Virtual Private Network (VPN) encrypts the data being transmitted between the client and the cloud environment, providing a secure channel that protects against unauthorized access, eavesdropping, and data tampering. This encryption is essential for maintaining the confidentiality and integrity of sensitive information as it moves across the internet or through public networks.

While regularly updating firewall rules is important for overall security, it primarily addresses incoming and outgoing traffic rather than specifically securing data-in-transit. Utilizing HTTP instead of HTTPS undermines security, as HTTP does not provide encryption, leaving the data exposed during transmission. Limiting access to cloud resources only during business hours may provide some control over access but does not specifically address the need for safe transmission of data as it moves across networks. Therefore, setting up a VPN tunnel is a proactive approach to safeguarding the integrity and confidentiality of data while it is in transit.
