Securing wireless LANs

Securing wireless networks is a critical component of an organization’s security plan. Learn about Wi-Fi security standards, such as WEP, WPA, and WPS, and find out more about RFID, NFC and Bluetooth.

  • Wi-Fi encryption standards Video — 00:09:42
    • Securing Wi-Fi networks is crucial since physical access is not required to gain network access. In this video Wi-Fi security standards such as WEP, WPA, and WPS are discussed.

  • Ask me anything Video — 00:01:16
    • Some wireless networking attacks involve deception. In this episode, Mike describes how there are variations of Evil Twin attacks including through DNS.

  • Exam question review Video — 00:01:42
    • Malicious users will often mimic legitimate services in an attempt to trick unsuspecting victims into connecting to the service. This episode presents a scenario where the viewer must determine what type of attack has taken place.

  • Wi-Fi hardening Video — 00:10:30
    • There are many options for securing Wi-Fi networks. Disabling items such as WLAN name broadcast, DHCP, and public network management are the first consideration. Using WPA3 enterprise mode and changing default settings also help harden your Wi-Fi network.

  • Wi-Fi discovery and attacks Video — 00:12:09
    • Is your Wi-Fi network completely invisible if you disable SSID broadcasting? No! Periodic beacon frames are still sent wirelessly with the WLAN name field excluded. Freely available tools can be used to discover and crack WEP and WPA passphrases.

  • RFID, NFC, and Bluetooth Video — 00:06:50
    • While there are many wireless network standards, which ones are designed for close proximity? This video covers RFID, NFC and Bluetooth wireless network communications.

  • Security+ – Web Vulnerabilities Lab — 00:30:00
    • Because of the need to be public-facing and the information they provide, websites and web servers are a common target of attacks. The path to exploiting these attacks is most commonly created by logical errors in development or using vulnerable software to aid in building up the website. What adds to the pool of possible weak points is the need to integrate several technologies to create an interactive and responsive user experience, usage of legacy systems and failure to keep up with security patches. All these factors amount to a vast number of threats, all specific to different versions and programming languages.

  • WPA2 cracking lab Video — 00:06:28
    • Wi-Fi Protected Access (WPA) protects Wi-Fi network communications. This episode demonstrates how there are ways to crack a WPA2 using offline attack methods.

  • Cracking WPA2 Video — 00:10:24
    • One way to crack WPA2 passphrases is to de-authenticate an existing connected client, then capture and analyze the client re-authenticating. This episode will demonstrate how to perform an offline dictionary attack using a WPA2 authentication packet capture file.

  • Wi-Fi coverage and performance Video — 00:08:20
    • Optimizing Wi-Fi communication means ensuring there is proper coverage over a given area and that there are no wireless interference issues from other transmitting devices. A wireless site survey with a heat map can identify overlapping Wi-Fi channels or wireless dead spots where connectivity may need to be improved.
