You are a system administrator setting up a secure connection for employees to access the corporate network remotely. Which of the following best practices should you implement to ensure secure communication?
Allow split tunneling without restriction
Require multifactor authentication for access
Use strong encryption protocols such as AES-256 for the connection
The correct answer is 'Use strong encryption protocols such as AES-256 for the connection.' Strong encryption protocols like AES-256 (Advanced Encryption Standard with 256-bit keys) ensure that the data transmitted over the connection is secure and less vulnerable to attacks. 'Requiring multifactor authentication' is a good practice but does not pertain specifically to securing the communication channel itself. 'Using outdated encryption protocols like DES' is not secure as DES (Data Encryption Standard) is considered weak. 'Allowing split tunneling without restriction' can expose the network to security risks if users can access potentially insecure external networks while connected.
