open wifi – in 2018 none should access untrusted unsecured wireless networks anymore

wpa encryption – works with “handshake” to ensure trust between devices – wpa2 added advanced encryption standart (aes) – wpa2 is vulnerable: key reinstallation attacks – wi-fi alliance announced wpa3 with additional security features

public wifi – when accessing a wifi while shopping, your devices are redirected to a captive portal to accept policies and establish a secure connection

vpn – apps like nordvpn esablish secure connection to add another layer of security, browse incognito through the internet

business – could use radius protocol to check validity of authentification – further enroll client certificate via mdm to authenticate via 802.1x – aruba clearpass can check devices status in mdm to ensure security and trust at the entire cycle

rouge access – attacker can fake access points to start a man in the middle (mitm) attack, intercept your private data, for example this pineapple nano

hashcat – new technique allow to get all the information they need to brute force decrypt a Wi-Fi password, by snooping on a single data packet going over the air

ssl srip – a method to redirect traffic from https to http to force unencrypted transport – every passcode is unprotected, even it is shown as secure

mobile devices management – is a way to protect company devices, e.g. disallow profile installation – but in a byod or mam-only scenario you can’t disable all features

mobile thread defense – mtd is for private and business devices, check behaviour and use ai to protect – like lookout as cloud service and additionally on device like zimperium, partners with mobileiron
