In a server environment, which action would typically enhance the security of data in transit?

• A. Using VPN
• B. Implementing RAID
• C. Regular software updates
• D. Physical security measures

Answer: (A)

Using a VPN, or Virtual Private Network, is a widely recognized method for enhancing the security of data in transit. It creates a secure tunnel between the user’s device and the destination server, encrypting the data being transmitted over the network. This encryption protects sensitive information from being intercepted by unauthorized users, such as hackers or anyone on a public network. By masking the user's IP address and securing the connection, a VPN ensures that the data remains confidential and integral as it travels across potentially insecure channels like the internet. The other options, while important for overall security, do not specifically address the security of data during transmission. Implementing RAID primarily focuses on data redundancy and improving availability rather than securing data in transit. Regular software updates are crucial for patching vulnerabilities and security flaws but mainly protect the system and data at rest rather than moving data. Lastly, physical security measures protect hardware and restrict access to facilities, but they do not control or secure data being transmitted over networks. Thus, using a VPN is the most effective option for safeguarding data as it travels.
