Final answer:
The question pertains to a corporate security policy enforcing the use of secure tunnels, like VPNs, for remote data communications to a LAN. This guarantees encryption of transmitted data, safeguarding it against unauthorized access.
Step-by-step explanation:
The corporate security policy that requires all remote connections to use only secure tunnels for data communications LAN implies the use of Virtual Private Network (VPN) technology or similar secure tunneling protocols.
Secure tunnels ensure that data transmitted over a public network, such as the internet, is encrypted and protected from eavesdropping or interception. This is particularly important for organizations that require remote access to their Local Area Network (LAN) resources to maintain data confidentiality and integrity.
Common protocols used to establish secure tunnels include Secure Sockets Layer (SSL) VPN, Transport Layer Security (TLS), and Internet Protocol Security (IPsec). These protocols provide a secure and encrypted connection between a remote user's device and the corporate network, adhering to the organizational security policy mentioned.
