Summary  
This chapter explains how to implement encryption protocols, access control methods, and monitoring mechanisms to protect data transmissions and restrict unauthorized device access.  

General domain of usage  
Wireless network security

**Wireless networks** offer flexibility and convenience, but they also introduce additional security vulnerabilities compared to wired networks. Securing wireless networks involves using a combination of **encryption**, **access control**, and **monitoring** to mitigate these risks and ensure data remains protected.

Why is it important to change the default SSID and password of a wireless router?

Explore the essentials of network security and understand how modern systems are protected from cyber threats. Learn about common network attacks, firewalls, intrusion detection systems (IDS), encryption, VPNs, and the key principles of securing wireless networks.
