Cybersecurity for Small Networks
Cybersecurity for Small Networks is a straightforward guide to improving network security whether you’re running Linux, Windows, or macOS.
As you work through the book’s projects, you’ll learn core hardening techniques like how to map a network, track the status of devices, and recognize unusual activity that might signal an attack. You’ll explore ways to eliminate vulnerabilities and prevent unwanted access to mobile, desktop, or even IoT endpoints. You’ll also learn how to implement custom back-up strategies and how to detect, prevent, and mitigate malware or ransomware attacks.
On the still more technical side, you will:
- Use and configure firewalls like pfSense and iptables to filter network traffic
- Create a network segmentation plan to separate devices by risk, manage user access, and configure wireless authentication
- Deploy OpenVPN or Wireguard network-wide to encrypt and protect network communication
- Use a Squid proxy to obfuscate personal or business data and control web traffic
- Implement a traffic access point (TAP) to capture and analyze network traffic, and build a Security Onion monitoring appliance to alert you to suspicious activity
No matter your level of experience, Cybersecurity for Small Networks will arm you with the tools and knowledge you need to lock down your network, and defend and recover from attacks.
“An excellent crash course for someone like me with a technical background but little security experience. I've always wanted to beef up my home server and network security but didn't know where to start . . . This book has given me actionable steps I can take today, this week, this month, and beyond. And it gives me the confidence that I'm following reasonable best practices for an actual small network.”
