Exploring Network Security with Raspberry Pi
Basic Concepts of Network Security
Network security encompasses safeguarding your network from unauthorized access, data breaches, and other cyber threats. A Raspberry Pi firewall plays a pivotal role in this process by enforcing security policies and vigilantly monitoring traffic for any suspicious activity, thereby ensuring a secure and protected digital environment.
Common Threats to Home Networks
Home networks are frequently targeted by various cyber threats, including:
- Malware and Viruses: Malicious software designed to disrupt or gain unauthorized access to computer systems.
- Phishing Attacks: Deceptive tactics aimed at stealing sensitive information such as login credentials and credit card numbers.
- DDoS Attacks: Distributed Denial of Service attacks overwhelm your network with excessive traffic, causing it to crash or become inaccessible.
- Unauthorized Access Attempts: Efforts by unauthorized individuals to gain access to your network without permission.
Unlocking Advanced Features of Raspberry Pi Firewalls
Virtual Private Networks (VPNs)
Incorporating a Virtual Private Network (VPN) with your Raspberry Pi firewall adds an extra layer of security by encrypting your internet traffic. This is particularly advantageous when accessing public Wi-Fi networks or handling sensitive information, ensuring your data remains confidential and secure.
Intrusion Detection Systems (IDS)
An Intrusion Detection System (IDS) continuously monitors your network for signs of malicious activity and promptly alerts you to potential threats. Many Raspberry Pi firewall solutions, including pfSense and OPNsense, come equipped with built-in IDS capabilities, enhancing your network's overall security posture.
Addressing Common Issues and Troubleshooting
