The bigger question is how to secure the computer that is in use at home and the connection between the computer and the enterprise network. You may want to assume that the local network or any network is hostile, and configure users' computers and remote connections to be resilient to attacks by using a host-based firewall and verifying that connections to your network are secure. Even if securing the home network is a losing battle, the most important points are to configure your computers securely, provide secure remote access to your enterprise network by using a VPN or similar technologies, and educate your users with basic information security skills to help prevent serious security issues.
