Hackers could have changed Facebook Messenger chat logs

Here's a Facebook hack straight from the pages of the novel 1984: A way to rewrite the record of the past."Who controls the past controls the future: who controls the present controls the past," went the ruling party's slogan in George Orwell's dystopian novel.Security researchers have found a way to control the past, by altering Facebook's logs of online chats conducted through its website and Messenger App.Such modified logs could be used to control the future, the researchers suggest, by using them to commit fraud, to falsify evidence in legal investigations, or to introduce malware onto a PC or phone.Roman Zaikin of Check Point Software Technologies discovered a flaw in Facebook's chat system that made it possible for an attacker to modify or remove any sent message, photo, file or link in a conversation they were part of.To read this article in full or to leave a comment, please click here

6 ways video can boost your business

According to a recent Aberdeen report, marketers who use video see much faster revenue growth (49 percent) than those who do not. However, video has become more than just a marketing tool. With their capability to visually explain and demonstrate things and concepts, videos can help businesses not only showcase their products and services, attracting new customers, but they can help companies attract new employees and even make workers more productive.Here are six cases where video can be beneficial.1. Explaining your value proposition/what you do Why tell people what you do when you can show them?To read this article in full or to leave a comment, please click here

Ghost story blogger has kinds words for Comcast

It's not every day I come across positive sentiments about Comcast, so I thought I'd share this example that I stumbled upon in a local blog focused on, of all things, ghost stories.Author Liz Sower writes realistic but fictional accounts of the paranormal at "Ghosts in the Burbs," and she caught my eye with this recent headline: Xfinity vs. Verizon. I thought for sure she was going to dive into haunted DSL or eerie broadband experiences.To read this article in full or to leave a comment, please click here

When you isolate your industrial control systems don’t forget about DNS

Many organizations that run industrial control systems strive to isolate them from the Internet, but sometimes forget to disallow Domain Name System (DNS) traffic, which provides a stealthy way for malware to exfiltrate data.Sometimes referred to as supervisory control and data acquisition (SCADA) systems, industrial control systems (ICS) are notoriously insecure. Not only is their firmware full of flaws, but the communication protocols many of them use lack authentication or encryption.Since most ICS systems are typically meant to last over a decade once deployed, they're not easily replaceable without considerable costs. As such, ICS operators tend to focus on securing the perimeter around control systems instead of patching the devices themselves, which is not always possible. This is done by isolating ICS environments from corporate networks and the larger Internet, an action sometimes referred to as airgapping.To read this article in full or to leave a comment, please click here

Endpoint detection and response: What’s important?

My colleagues Doug Cahill, Kyle Prigmore and I recently completed a research project on next-generation endpoint security. We determined that there are actually two distinct product categories within next-generation endpoint security: advanced prevention and advanced detection and response (EDR). While most firms seem to be gravitating toward advanced prevention, massive enterprise organizations tend to move in the opposite direction by evaluating, testing and deploying EDR products. Why? These organizations have large cybersecurity teams with lots of experience, so they are willing to dedicate resources toward more complex projects.Furthermore, many of these enterprise organizations are already investing in security analytics by collecting, processing and analyzing data from numerous disparate sources (i.e., network forensics, events/logs, threat intelligence, etc.). Endpoint forensic data is a natural extension of these cybersecurity analytics efforts. To read this article in full or to leave a comment, please click here

Download the New ‘Wi-Fi Design Poster’ Today!

Performing a proper Wi-Fi design is critical to success. Modern WLANs have grown ever more complex, having to provide high quality coverage, meet density and capacity requirements, facilitate user mobility and roaming, all while minimizing both Wi-Fi interference and external RF interference. The new 'Wi-Fi Design Poster' can provide a quick reference for wireless engineers. The poster was a collaborative effort between myself and Ekahau.

The poster covers the 4 critical aspects of Wi-Fi design, an overview of the design process, and 10 high-performance Wi-Fi tips and tricks.

Download and print yours today! It is available as both a poster and an infographic. We hope you like it :) Please share it if you think others would benefit as well.

Transfer by US of Internet oversight could face new hurdles

U.S. plans to transfer the oversight of key technical Internet functions to an international multi-stakeholder governance model have run into hurdles with two bills being introduced on Wednesday that would require the government to first take the approval of Congress for the transition.A bill proposed in the Senate by Ted Cruz, a Republican from Texas, called the Protecting Internet Freedom Act, would prohibit any transfer of Internet domain name system functions except if expressly allowed under a federal statute passed after the new legislation has been enacted.To read this article in full or to leave a comment, please click here

Do it now! From SHA-1 to SHA-2 in 8 steps

As deadlines go, Jan. 1, 2017, isn’t far away, yet many organizations still haven’t switched their digital certificates and signing infrastructure to use SHA-2, the set of cryptographic hash functions succeeding the weaker SHA-1 algorithm. SHA-1 deprecation must happen; otherwise, organizations will find their sites blocked by browsers and their devices unable to access HTTPS sites or run applications.7.

The most common is currently SHA-1, despite significant cryptographic weaknesses that render the certificates vulnerable to collision attacks.To read this article in full or to leave a comment, please click here(Insider Story)
