After a wave of zero-day attacks targeting widely used security and networking appliances, the Cybersecurity & Infrastructure Security Agency (CISA) is taking new measures to protect Internet-exposed networking equipment.

Increasingly, security teams are tasked with identifying, understanding, and managing risk around devices that may live outside the traditional IT umbrella. Operational Technology (OT) refers to computing systems that are used to manage and process operational functions as opposed to administrative operations, with Industrial Control Systems (ICS) being a major segment of that OT sector.

Network complexity is at an all-time high. Between legacy technology, hybrid-multi-cloud environments, and networks cobbled together by mergers and acquisitions, it’s impossible for people to keep track of the network, its topology, and behavior. The idea of trying to trace a path through a multi-cloud network seems akin to being asked to pull a rabbit out of your hat.

In our final OT:ICEFALL report, Forescout Vedere Labs presents three new vulnerabilities and concludes the project after one year of research following the original disclosure. The OT:ICEFALL research, including 61 vulnerabilities affecting 13 vendors, has yielded three key insights into the current state of OT product security.

Complexity is the new normal, which applies equally to businesses’ networks and wireless environments. This is complicated further by the fact that cyberattacks that seek to exploit vulnerabilities in organizations' WLANs (Wireless Local Area Networks) are becoming increasingly sophisticated. On World Wi-Fi Day, we want to offer you security tips to create a safer wireless environment.
