A free, almost foolproof way to check for malware

No single antimalware engine can keep up with all the malware out there. But how about 57 of 'em?In this video, you'll learn how to download and run Windows Sysinternals Process Explorer to test all currently running executables on your Windows system against VirusTotal's 57 antivirus engines, which together offer the best accuracy you can ever get (with a small percentage of false positives that are pretty easy to spot). Neither the Sysinternals Process Explorer software nor the VirusTotal service cost anything at all. The whole setup process will take you about five minutes and the scan, which you can execute any time you like, takes less than a minute. Only malware in memory will be detected, but if you're infected, very likely that malicious process will be running -- and this easy method will sniff it out. Watch and learn.To read this article in full or to leave a comment, please click here

Endpoint security still inadequate despite growing threats

Endpoint security solutions today are lacking in spite of significant gaps, vulnerabilities in security and heightened fear of a security breach, says Promisec, endpoint security and compliance vendor.According to Promisec data, 89 percent of VP and C-Level IT leaders who responded in a Promisec survey have a heightened fear of a breach over the next year while only 32 percent of respondents have advanced endpoint security in place.The fact that 73 percent of the respondents agree that endpoints are the most vulnerable point for attack should magnify concerns. The demand is there and analyst market valuations for endpoint security reflect that. The market value should grow from $11.62 billion this year to $17.38 billion by 2020, according to a recent MarketsandMarkets report. Analyst group TechNavio pegs the growth at a CAGR of 10.4 percent over the period 2014-2019.To read this article in full or to leave a comment, please click here

Transforming ideas into light bulbs – LiFi

About 4 years ago, Harald Haas, a physicist and professor of mobile communications at the University of Edinburgh, was the first to coin the term Li-Fi, at a TED Talk during TEDGlobal 2011. Since then, millions of bits about this technology roamed the Internet, and many companies already started implementing it.

Who’s doing this already?

The history begins with a company named Velmenni, which has produced a light bulb that works with Li-Fi technology on a small scale. They are not the first to prove the technology works, nor the first to conduct a real-world experiment, but here’s their Jugnu Lighbulb demo.

Philips has developed a VLC (Visible Light Communication) system for shoppers at stores. People have to download an app on their smartphone and then it will interact with the LEDs in the store. The LEDs can pinpoint their location in the store and give them corresponding coupons and information based on which aisle they are on and what they are looking at.ByteLight has developed a system similar to Philips’ lighting network, making LEDs “talk” to any smartphone and tablet with a camera and/or Bluetooth Smart technology that is “opened to listen”.

The first VLC smartphone prototype was Continue reading

CPLANE Networks on Software Gone Wild

When I wrote a blog post explaining the difference between centralized control and centralized control plane, John Casey, CEO of CPLANE Networks wrote a comment saying “yeah, that’s exactly what we’re doing.”

It took us a while to get the stars aligned, but finally we managed to sit down and chat about what they’re doing, resulting in Episode 46 of Software Gone Wild.

Custom metrics with Cumulus Linux

Cumulus Networks, sFlow and data center automation describes how Cumulus Linux is monitored using the open source Host sFlow agent that supports Linux, Windows, FreeBSD, Solaris, and AIX operating systems and KVM, Xen, XCP, XenServer, and Hyper-V hypervisors, delivering a standard set of performance metrics from switches, servers, hypervisors, virtual switches, and virtual machines.

Host sFlow version 1.28.3 adds support for Custom Metrics. This article demonstrates how the extensive set of standard sFlow measurements can be augmented using custom metrics.

Recent releases of Cumulus Linux simplify the task by making machine readable JSON a supported output in command line tools. For example, the cl-bgp tool can be used to dump BGP summary statistics:

cumulus@leaf1$ sudo cl-bgp summary show json
{ "router-id": "192.168.0.80", "as": 65080, "table-version": 5, "rib-count": 9, "rib-memory": 1080, "peer-count": 2, "peer-memory": 34240, "peer-group-count": 1, "peer-group-memory": 56, "peers": { "swp1": { "remote-as": 65082, "version": 4, "msgrcvd": 52082, "msgsent": 52084, "table-version": 0, "outq": 0, "inq": 0, "uptime": "05w1d04h", "prefix-received-count": 2, "prefix-advertised-count": 5, "state": "Established", "id-type": "interface" }, "swp2": { "remote-as": 65083, "version": 4, "msgrcvd": 52082, "msgsent": 52083, "table-version": 0, "outq": 0, "inq": 0, "uptime": "05w1d04h", "prefix-received-count": 2, "prefix-advertised-count": 5, "state": "Established", "id-type": "interface" } },  Continue reading

I use SNMP SETs and I’m not afraid to admit it.

Do you remember back in CCNA school when we learned all sorts of great things that we very rarely followed. One of the favourites was that we are supposed to put meaningful descriptions on all of our interfaces so we know what the other side is connected to.

How many people actually follow that advice?

Yeah, I never do it either. There’s always just too many things on the list that need to get done and it seems like that extra 5 seconds it would take me to update the description to the interface just doesn’t seem like it’s worth the effort. Of course, then I later check the port and end up knocking out my XYZ services and cause myself an outage.

This is where a little python and a decent NMS can help to solve a problem.

Understanding ifIndex

Before we get into the code. We need to understand a little about ifIndex values and how they relate to the physical interfaces of the devices. If you’re REALLY interested, you can do some reading in RFC 2863.  But in a nutshell, each interface on a device, whether physical or logical has a specific numeric value assigned to it Continue reading

Policy wonks aren’t computer experts

This Politico story polls "cybersecurity experts" on a range of issues. But they weren't experts, they were mostly policy wonks and politicians. Almost none of them have ever configured a firewall, wrote some code, exploited SQL injection, analyzed a compromise, or in any other way have any technical expertise in cybersecurity. It's like polling a group of "medical experts", none of which has a degree in medicine, or having a "council of economic advisers", consisting of nobody with economics degrees, but instead representatives from labor unions and corporations.

As an expert, a real expert, I thought I'd answer the questions in the poll. After each question, I'll post my answer (yes/no), the percentage from the Politico poll of those agreeing with me, and then a discussion.

Should the government mandate minimum cybersecurity requirements for private-sector firms?

No (39%). This question is biased because they asked policy wonks, most of which will answer "yes" to any question "should government mandate". It's also biases because if you ask anybody involved in X if we need more X, they'll say "yes", regardless of the subject you are talking about.

But the best answer is "no", for three reasons.

Firstly, we experts don't know Continue reading

The latest IoT network builds on a power-grid foundation

New networks being built with far less fanfare than cell towers will connect objects that in some cases have never been linked before, like street lights and traffic signals. The latest, called Starfish, is now debuting in Silicon Valley.The many new dedicated networks for the Internet of Things aren't as fast as LTE or Wi-Fi, but they're designed to reach devices across an entire region with lower cost and power consumption. That's part of the equation that's supposed to make IoT work.But as a new kind of network, these LPWA (low-power wide area) technologies are still a Wild West of competing vendors and approaches. Take your pick: Ingenu, SigFox, LoRaWAN, NB-LTE and more. To read this article in full or to leave a comment, please click here

This Japanese security drone will chase intruders

Security guards in Japan have a new tool to deter intruders: a drone that will chase down and follow people without human intervention.Made by Secom, Japan's biggest security company, the drone goes on sale Friday to organizations that need to protect large parcels of land. It will launch whenever suspicious cars or people are detected on the property by other security equipment.The drone will snap pictures and send them to a Secom monitoring center where it can determine the threat. Today, the company sends security guards to investigate potential intrusions, so a drone could reduce its response time considerably.To read this article in full or to leave a comment, please click here

Using SSH Multiplexing

In this post, I’m going to discuss how to configure and use SSH multiplexing. This is yet another aspect of Secure Shell (SSH), the “Swiss Army knife” for administering and managing Linux (and other UNIX-like) workloads.

Generally speaking, multiplexing is the ability to carry multiple signals over a single connection (see this Wikipedia article for a more in-depth discussion). Similarly, SSH multiplexing is the ability to carry multiple SSH sessions over a single TCP connection. This Wikibook article goes into more detail on SSH multiplexing; in particular, I would call your attention to the table under the “Advantages of Multiplexing” to better understand the idea of multiple SSH sessions with a single TCP connection.

One of the primary advantages of using SSH multiplexing is that it speeds up certain operations that rely on or occur over SSH. For example, let’s say that you’re using SSH to regularly execute a command on a remote host. Without multiplexing, every time that command is executed your SSH client must establish a new TCP connection and a new SSH session with the remote host. With multiplexing, you can configure SSH to establish a single TCP connection that is kept alive for a specific period Continue reading

Technology Short Take #57

Welcome to Technology Short Take #57. I hope you find something useful here!

Networking

• Tor Anderson has an article on using IPv6 for network boot using UEFI and iPXE.
• Larry Smith Jr. has a great blog series going called “Hey, I can DevOps my Network too!” He started out with an intro post just to set the stage for the series, then had a post on the prep work required to get ready to proceed with the series. In part 2 Larry walks through the node definitions in Vagrant, and in part 3 he reviews the Vagrantfile and turns up the environment. Parts 4 and 5 walk through auto-configured OSPF and manually-configured OSPF, respectively. I’m looking forward to more posts in this series!
• Sometimes I see blog posts that tout themselves as a “deep dive” but aren’t really that deep or detailed. However, this OVN L3 deep dive by Gal Sagie really is a deep dive—he goes into a pretty fair amount of detail on how OVN’s L3 implementation works. Good stuff if you’re interested in getting more details on how OVN is implementing new features like L3.
• Kirk Byers has a helpful article that provides some Continue reading
