Wirelesssecurity is the protection of wirelessnetworks, devices and data from unwanted access and breaches. It involves a variety of strategies and practices designed to preserve the confidentiality, integrity and availability of wirelessnetworks and their resources. What is WirelessSecurity?
Networksecurity threats weaken the defenses of an enterprise network, endangering proprietary data, critical applications, and the entire IT infrastructure. This guide to major networksecurity threats covers detection methods as well as mitigation strategies for your organization to follow.
Check Point experts discovered a high-severity flaw in Philips Hue Smart Light Bulbs that can be exploited to gain entry into a targeted WiFi network. The bridge discovers the hacker-controlled bulb with updated firmware, and the user adds it back onto their network. ZigBee is an IEEE 802.15.4-based
Many people assume that WiFi is short for “wireless fidelity” because the term “hi-fi” stands for “high fidelity.” ” Some members of the WiFi Alliance, the wireless industry organization that promotes wireless technologies and owns the trademark, may even have encouraged this misconception.
These are the leaders in networking, and accounting for nearly 70% of the market.” ” At the time it is not clear the exact number of affected devices, it has been estimated that Cisco and Aruba Networks provide 70% of the wireless access points sold to enterprises every year. or earlier. ” continues the post.
Networks connect devices to each other so that users can access assets such as applications, data, or even other networks such as the internet. Networksecurity protects and monitors the links and the communications within the network using a combination of hardware, software, and enforced policies.
The problem: D-Link’s DAP-2310 Wireless Access Point vulnerability known as “BouncyPufferfish” allows for unauthenticated remote code execution. ” To reduce risks, replace unsupported equipment, apply available firmware updates, and keep an accurate IT asset inventory. or later to fix the vulnerability.
Industrial Networks Communication networks are crucial for connecting all components of an ICS. These networks enable data exchange between PLCs, RTUs, SCADA systems, and HMIs. Industrial networks include wired and wireless technologies such as Ethernet, Modbus, and Profibus.

Common in all the affected devices is firmware from Arcadyan, a communications device maker. Vulnerabilities like these highlight the difficulty in assessing network problems, according to Yaniv Bar-Dayan, co-founder and CEO of Vulcan Cyber, a risk remediation firm.
The emergence of SD-WAN and SASE technologies bundled together has led many vendors to address both advanced routing and networksecurity vendors for clients. Networking specialists like Cisco and HPE’s Aruba are moving deeper into security. Palo Alto Networks.
Deploy patches Add multi-factor authentication to security controls Upgrade or replace vulnerable IT Resource Isolate and protect vulnerable IT Resource (network segmentation, disconnect wireless access, etc.) Appendix I.
Firmware attacks: Attackers target vulnerabilities in the simplified software that runs computer hard drives, printers, medical devices, and other Internet of Things (IoT) or operational technology (OT) devices to gain unauthorized access, control the devices, or use them as a launching pad for other attacks.
And so I was always kind of into you know, wireless stuff. It's always seems kind of magical, I guess to people, you know, wireless transmission and everything else and how it works. It's not networksecurity where you can download a spec or code and analyze it on your Linux box. To this research.
“So, for example, if you’re enclaving off a bunch of IoT devices so that they are protected from the internet, you may also be protecting them from firmware updates. And how do you vet those firmware updates? There are all kinds of interesting challenges that will need to be sorted out.”.
The updates are done through firmware, firmware updates that we get from the vendor. The wireless Bill has been around for quite some time. Their security researchers know that maybe they have firmware or maybe they found a program or something somewhere. So persons that are the adversary got into your network.
The wireless village has been around for quite some time. There is other ones such as the car hacking village and stuff but so the the API says village started several years ago at DEF CON to bring education awareness and exposure to industrial control systems technology security. At that time, there was a few other ones.
