Book Review: Practical Packet Analysis: Using Wireshark to Solve Real-World Network Problems

The overall equation is pretty simple: If you want to understand network traffic, you really should install Wireshark. And, if you really want to use Wireshark effectively, you should consider this book. Already in its third edition, Practical Packet Analysis both explains how Wireshark works and provides expert guidance on how you can use the tool to solve real-world network problems.Yes, there are other packet analyzers, but Wireshark is one of the best, works on Windows, Mac, and Linux, and is free and open source. And, yes, there are other books, but this one focuses both on understanding the tool and using it to address the kind of problems that you're likely to encounter.To read this article in full, please click here

Acer’s new Holo 360 is a 360-degree camera in a smartphone

The effort to grow in the virtual reality market has Acer chasing weird, but rather interesting, devices.The company introduced the Holo 360 camera, which is first and foremost a 360-degree camera. It can capture 3D content, much like other 360-degree cameras, and could be used to capture, view, and create content for VR headsets.But, seemingly as an afterthought, the device also has WiFi and LTE connectivity. The device itself looks like a bulky smartphone and can be used to make phone calls. It has a small screen, much like those on candy-bar phones.It's clearly not designed to be a full-fledged smartphone. No information about the chipset was provided. Different countries have different types of networks, and not all modems support all networks, especially in countries like China.To read this article in full or to leave a comment, please click here

How Google and Amazon think about multi-cloud workloads

It was not a big announcement from Google this week, but in a way it could be seen as a symbolic one.In a blog post, Google announced new functionality that will allow its Cloud Endpoints API (Application Programming Interface) management platform to integrate with Amazon Web Service’s Lambda functions-as-a-service product. The idea is you can build an application in Lambda and use Google Cloud’s Endpoints to manage API calls associated with it.+MORE AT NETWORK WORLD: Serverless explainer: The next generation of cloud infrastructure +To read this article in full or to leave a comment, please click here

2.4GHz is a headache for Wi-Fi users, and it’s here to stay

Current-generation Wi-Fi technology lives in the 5GHz band. Almost all of the major innovation in wireless standards takes place in the relatively untroubled frequencies around 5GHz (and well above), where there’s little radio competition and the living is easy.But wireless LAN users can’t just stay comfortable in the 5GHz realm – the older 2.4GHz frequency bands are a necessary part of most wireless implementations, and they’re rarely a favorite of the people who have to build and operate Wi-Fi networks.+ ALSO ON NETWORK WORLD: Toward a bigger, faster, denser Wi-Fi WorldTo read this article in full or to leave a comment, please click here

Advances in multifactor authentication (MFA) technologies

Enterprises authenticate users based on their knowledge, possession, or inherence of some evidence that they are the party with the given right of access. Some experts see the context of the user’s authentication such as the time, their network IP and device, and their location as the fourth factor of authentication.Stephen Cobb, senior security researcher at ESET says you can assure greater security with each additional factor of authentication that you add.MFA is more important than ever as attackers are increasingly breaking into accounts that use single-factor authentication and sometimes even those with two factors. In one example, attackers tried to get the second factor by using phishing texts that asked users to send over their tokens.To read this article in full or to leave a comment, please click here

Sensitive data often follows former employees out the door

There is an old cliché that says a company's most valuable assets walk out the door at the end of the day. However, according to a recent security report, some other valuable assets are walking out the door as well, and they're not coming back.In a survey from Osterman Research, 69 percent of organizations polled say that they have suffered significant data or knowledge loss resulting from employees who took information resources with them when they left the business.Any form of data loss is a threat to a business, but the report notes that problems can arise both from employees actually taking data with them when they leave, and when departing employees have parked corporate information in locations like cloud storage services that are unknown or inaccessible to their former employer.To read this article in full or to leave a comment, please click here

Failure to communicate helps ransomware prosper

At least one of the major reasons for the ongoing exponential increase in ransomware as a criminal business model could be summed up with the iconic line from the prison boss in 1967’s “Cool Hand Luke”: “What we got here is a failure to communicate.”That was a recurring theme from those on a “Ransomware Panel” Thursday at SOURCE Boston 2017, moderated by Paul Roberts, founder and editor in chief of The Security Ledger.The communication breakdown occurs at all levels, the panelists said, starting with victims. ■ MORE FROM SOURCE Boston: Cyber infrastructure: Too big to fail, and failing Frank McLaughlin, a Boston Police detective, said when a business gets hit with ransomware, “the police are the last people they want to call, for obvious reasons. It becomes a public record.”To read this article in full or to leave a comment, please click here
