Course Outline

Basics of wireless networks IEEE 802.11 standard - history, versions, principles of operation IEEE 802.11 messages - format, transmitted information, applications Devices - access points, repeaters, client stations Architecture and design of wireless networks Security mechanisms used in WiFi networks Security systems: WEP, WPA Mechanisms Encryption and Ensuring Integrity Authentication: Shared Key, IEEE 802.1x WPS - simple client connection Security issues in WiFi networks WiFi network reconnaissance - hardware and software SSID hiding and MAC address filtering - effectiveness analysis DoS attacks and affecting the performance of WEP networks - simple attacks for encryption (aircrack-ng, kismet) WEP - advanced mechanisms (Chop-Chop attacks, Caffe-Latte, fragmentation, fake authentication, replay) WPA - brute force attacks, attacks on PMKID and exploiting vulnerabilities (KRACK) WPS - implementation problems , password repeatability, brute force attacks (reaver, bully, pixiewps) How to increase password cracking efficiency? (calculations on GPU, rainbow tables) Other vulnerabilities and errors on network devices (routersploit package and others) Social engineering and fake WiFi networks (Fluxion, wifipumpkin3, WiFi Pineapple) Network security analysis packages (wash, wifite, airgeddon) IEEE authentication system 802.1x What is IEEE 802.1x and WPA-Enterprise? Authentication protocols - RADIUS, Diameter, TACACS EAP authentication methods and their weaknesses (EAP-MD5, EAP-TLS, EAP-TTLS, EAP-FAST and others) WPA-Enterprise wireless network configuration (based on FreeRADIUS server) Reconnaissance and network security WPA-Enterprise (eapeak) Securing WiFi networks IPS/IDS systems - general approach Wireless IPS Design and separation of traffic in WiFi networks How to design a secure hotspot? Physical security (RF shielding) Privacy in wireless networks - what to watch out for and what information can be obtained from WiFi?
