Defense in Depth for a Small Office/Home Office

Much attention is given to enterprise security with expensive solutions and teams of both IT and security personnel, but the home office may only ever be proactively defended by a single amateur or hobbyist. Large scale corporate solutions may deal with Advanced Persistent Threats (APTs) and corporate espionage, but there are far fewer solutions to home office threats. This paper focuses on best practices for a home network running minimal servers to protect from casual browsing and careless home users. This research intends to demonstrate meaningful defense of endpoints in a local network by drastically reducing potential communication to C2 nodes and data exfiltration with proper filtering and minimal extra hardware.
