Network Security Basics

Welcome to the basics of network security! In this guide, we'll cover the fundamentals of keeping your data and devices safe on the internet.

What is Network Security?

Network security is the practice of protecting your network from unauthorized access, misuse, modification, or destruction. This includes protecting both the hardware and software components of your network.

Common Threats

Here are some common threats that you should be aware of:

Malware: Software designed to damage, disrupt, or gain unauthorized access to computer systems.
Phishing: A type of cyber attack where an attacker tries to steal your personal information by pretending to be a trustworthy entity.
DDoS Attacks: Distributed Denial of Service attacks that overload a network or system, rendering it unusable.
Man-in-the-Middle (MitM): An attacker intercepts and potentially alters the communication between two parties.

Best Practices

To protect your network, follow these best practices:

Use Strong Passwords: Make sure all your accounts have strong, unique passwords.
Keep Software Updated: Regularly update your operating system and applications to patch vulnerabilities.
Use a Firewall: A firewall helps protect your network from unauthorized access.
Backup Your Data: Regularly back up your important files to prevent data loss.
