How automated investigation can accelerate threat detection

Finding threats quickerImage by ThinkstockCyber‫ security analysts are overwhelmed with the pressure of keeping their companies safe. Not only do they need to filter through countless alerts, many of which turn out to be false positives, but also the volume of real threats is growing exponentially. They quickly need to triage and move on, stopping the most pressing threats – but not always the most dangerous. Cyber analysts need a new, holistic approach to threat detection that monitors, analyzes and cross-references data across multiple dimensions to help them detect complex threats as early as possible.To read this article in full or to leave a comment, please click here

Security analysis of popular IoT devices

Have you wondered if your internet-connected devices are infected with Mirai malware and were part of the DDoS attacks?In response to the recent IoT DDoS attacks, researchers at Zscaler analyzed IoT traffic patterns not only on the days of the DDoS attacks on Dyn and Krebs on Security, but going back to July.While Zscaler does not believe any of the devices connected to Zscaler Cloud had been compromised and used in the IoT botnet attacks, ThreatLabz researchers analyzed the security of five security cameras, three smart TV entertainment devices, three smart network printers and scanners, two DVRs and NVRs, two IP phones and a partridge in a pear tree. The last one of course was just to see if you were paying attention: no partridges were harmed in the course of this research.To read this article in full or to leave a comment, please click here

IDG Contributor Network: What is the General Data Protection Regulation and why should you care?

In 2012, the European Commission proposed new regulations on data protection that would supersede the national laws of the 28 EU member states. It was formally approved in April this year, and it will go into effect May 25, 2018. This General Data Protection Regulation (GDPR) introduces several major changes that will impact many organizations worldwide. The smart move is to familiarize yourself with the incoming regulation now, and begin preparing to comply with your obligations. The GDPR will apply to any business that operates within the EU, but also any company that processes data from EU citizens. It doesn’t matter where the organization is located.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Is your network a platform for business innovation and growth?

The whole point of a network is just to connect stuff, right? Connect people to people, people to machines, and machines to machines. It’s pipes and plumbing, a necessary part of the business infrastructure and, hopefully, one that costs less and less over time. After all, it’s a cost center not a growth engine. At least, that’s the way it’s treated by most businesses these days.Most, but not all.+ Also on Network World: Accelerating business innovation: Don't let networks get in the way +To read this article in full or to leave a comment, please click here

Healthcare, retail industries give blockchain a try

The U.S. Department of Health and Human Services hopes to put a new technology to use in its ongoing effort to improve the health and well-being of Americans. The technology in question isn't something one might expect to see in the healthcare IT toolkit; rather, it's blockchain, the technology that underpins cryptocurrency and has primarily been associated with bitcoin. HHS sees blockchain as a potential salve for ills that plague the increasingly complex world of digital health records.To read this article in full or to leave a comment, please click here(Insider Story)

This malware attack starts with a fake customer-service call

Hotel and restaurant chains, beware. A notorious cybercriminal gang is tricking businesses into installing malware by calling their customer services representatives and convincing them to open malicious email attachments. The culprits in these hacks, which are designed to steal customers’ credit card numbers, appear to be the Carbanak gang, a group that was blamed last year for stealing as much as $1 billion from various banks. On Monday, security firm Trustwave said that three of its clients in the past month had encountered malware built with coding found in previous Carbanak attacks.To read this article in full or to leave a comment, please click here

Network Automation Survey

Network Automation is just getting started and it’s odd to say that as IT professionals from other technology disciplines are always surprised to see how much manual interaction there still is between the networking engineering/operations teams and the actual devices they manage.

I’ll never forget the days in 2012-2013 performing my best Google searches to find ways to program or to automate network routers and switches. I didn’t care what programming language was being used or even what tool, but I found nothing. Every time I heard someone say they were using a network script, I’d say “email it to me, that sounds interesting.” Unfortunately, 100% of the time, it ended up being a notepad or a Word file, not a script. What a bummer.

I like to think I’m a solid Googler too. It was amazing though - there was near nothing. Do a search today on network automation or network programming and you’d be amazed on what you’ll find - we’ve come a long way in the past 36 months with respect to network automation, but I truly believe we’re still in the 2nd or 3rd inning (if we were playing a game of baseball, of course).
