Report: Mirai tries to hook its tentacles into SD-WAN

Network World - Fri, 06/14/2019 - 12:16pm

Mirai – the software that has hijacked hundreds of thousands of internet-connected devices to launch massive DDoS attacks – now goes beyond recruiting just IoT products; it also includes code that seeks to exploit a vulnerability in corporate SD-WAN gear.

That specific equipment – VMware’s SDX line of SD-WAN appliances – now has an updated software version that fixes the vulnerability, but by targeting it Mirai’s authors show that they now look beyond enlisting security cameras and set-top boxes and seek out any vulnerable connected devices, including enterprise networking gear.

IoT security vs. privacy: Which is a bigger issue?

Network World - Wed, 06/12/2019 - 5:30am

If you follow the news surrounding the internet of things (IoT), you know that security issues have long been a key concern for IoT consumers, enterprises, and vendors. Those issues are very real, but I’m becoming increasingly convinced that related but fundamentally different privacy vulnerabilities may well be an even bigger threat to the success of the IoT.

In June alone, we’ve seen a flood of IoT privacy issues inundate the news cycle, and observers are increasingly sounding the alarm that IoT users should be paying attention to what happens to the data collected by IoT devices.

Predictably, most of the teeth-gnashing has come on the consumer side, but that doesn’t mean enterprises users are immune to the issue. One the one hand, just like consumers, companies are vulnerable to their proprietary information being improperly shared and misused. More immediately, companies may face backlash from their own customers if they are seen as not properly guarding the data they collect via the IoT. Too often, in fact, enterprises shoot themselves in the foot on privacy issues, with practices that range from tone-deaf to exploitative to downright illegal—leading almost two-thirds (63%) of consumers to describe IoT data collection as “creepy,” while more than half (53%) “distrust connected devices to protect their privacy and handle information in a responsible manner.”

Free course - Ethical Hacking: Hacking the Internet of Things

Network World - Wed, 06/12/2019 - 12:46am

IoT devices are proliferating on corporate networks, gathering data that enables organizations to make smarter business decisions, improve productivity and help avoid costly equipment failures, but there is one big downside – security of the internet of things remains a problem.

It makes sense, then, for enterprises to try to spot vulnerabilities in the IoT gear in their networks before they can be exploited by malicious actors.

Cisco security spotlights Microsoft Office 365 e-mail phishing increase

Network World - Wed, 05/29/2019 - 4:52pm

It’s no secret that if you have a cloud-based e-mail service, fighting off the barrage of security issues has become a maddening daily routine.

The leading e-mail service – in Microsoft’s Office 365 package – seems to be getting the most attention from those attackers hellbent on stealing enterprise data or your private information via phishing attacks. Amazon and Google see their share of phishing attempts in their cloud-based services as well.

But attackers are crafting and launching phishing campaigns targeting Office 365 users, wrote Ben Nahorney, a Threat Intelligence Analyst focused on covering the threat landscape for Cisco Security in a blog focusing on the Office 365 phishing issue.

Survey finds SD-WANs are hot, but satisfaction with telcos is not

Network World - Wed, 05/29/2019 - 3:10pm

This week SD-WAN vendor Cato Networks announced the results of its Telcos and the Future of the WAN in 2019 survey. The study was a mix of companies of all sizes, with 42% being enterprise-class (over 2,500 employees). More than 70% had a network with more than 10 locations, and almost a quarter (24%) had over 100 sites. All of the respondents have a cloud presence, and almost 80% have at least two data centers.  The survey had good geographic diversity, with 57% of respondents coming from the U.S. and 24% from Europe.

Highlights of the survey include the following key findings:

Study: Most enterprise IoT transactions are unencrypted

Network World - Thu, 05/23/2019 - 4:07pm

Of the millions of enterprise-IoT transactions examined in a recent study, the vast majority were sent without benefit of encryption, leaving the data vulnerable to theft and tampering.

The research by cloud-based security provider Zscaler found that about 91.5 percent of transactions by internet of things devices took place over plaintext, while 8.5 percent were encrypted with SSL. That means if attackers could intercept the unencrypted traffic, they’d be able to read it and possibly alter it, then deliver it as if it had not been changed.
