Summary  
This chapter covers the implementation of encryption protocols, authentication filters, and monitoring systems in code to protect data transmission and enforce access control, demonstrating how to integrate multi-layered security measures.  

General domain of usage  
Wireless network security

**Trådløse nettverk** gir fleksibilitet og bekvemmelighet, men introduserer også flere sikkerhetssårbarheter sammenlignet med kablede nettverk. Sikring av trådløse nettverk innebærer bruk av en kombinasjon av **kryptering**, **tilgangskontroll** og **overvåking** for å redusere disse risikoene og sikre at data forblir beskyttet.

Hvorfor er det viktig å endre standard SSID og passord på en trådløs ruter?

Nettverksgrunnleggende er et omfattende kurs utviklet for nybegynnere og viderekomne som ønsker å bygge praktiske ferdigheter innen nettverk. Kurset dekker alt fra grunnleggende konsepter til avanserte anvendelser, og tar deg gjennom sentrale emner som nettverkstyper, IP-adressering, protokoller og nettverkssikkerhet. Etter endt kurs vil du ha nødvendige ferdigheter for å feilsøke, sikre og administrere nettverk effektivt, og legge et solid grunnlag for videre spesialisering innen nettverk.

Learn about the history and evolution of networking technologies and how modern communication systems rely on networks. This section provides a comprehensive overview of how devices communicate and share resources efficiently across different types of networks.

Discover the fundamental role of IP addressing in identifying devices on a network and how subnetting helps optimize network efficiency. This section covers the basics of IP addressing, introduces subnetting techniques to segment networks, and explores how these concepts contribute to smooth communication across connected devices.

Explore the foundational rules and protocols that govern how data is transmitted and received over networks. This section delves into essential networking models, such as the OSI Model and the TCP/IP Model, while covering widely-used protocols like HTTP, FTP, and DNS. Understanding these protocols ensures that devices communicate effectively, regardless of their underlying technologies, creating seamless interactions between global networks.
