Tracie Thompson, CEO, HackHunter A company's Wi-Fi network is an ever-present target for attackers, and the range of risks, particularly in an era of pervasive IoT, continues to grow. IT security pros work to ensue unauthorized devices, including video cameras, small hacking tools and BYOD items, don't join the network. Also a threat are so-called "evil twin" attacks, where an attacker creates an access point that masquerades as a real one in order to get victims to connect. Regularly auditing corporate Wi-Fi is a best practice, says Tracie Thompson, CEO and co-founder of the Australian startup HackHunter. PCI-DSS requires regular Wi-Fi audits as well as the removal of unauthorized access points, she points out.
