Build security into your IoT plan or risk attack

The Internet of Things (IoT) is no longer some futuristic thing that’s years off from being something IT leaders need to be concerned with. The IoT era has arrived. In fact, Gartner forecasts there will be 20.4 billion connected devices globally by 2020.An alternative proof point is the fact that when I talk with people about their company's IoT plans, they don’t look at me like a deer in headlights as they did a few years ago. In fact, often the term “IoT” doesn’t even come up. Businesses are connecting more “things” to create new processes, improve efficiency, or improve customer service.As they do, though, new security challenges arise. One of which is there's no “easy button.” IT professionals can’t just deploy some kind of black box and have everything be protected. Securing the IoT is a multi-faceted problem with many factors to consider, and it must be built into any IoT plan.To read this article in full, please click here

What is a firewall? How they work and how they fit into enterprise security

Firewalls been around for three decades, but they’ve evolved drastically to include features that used to be sold as separate appliances and to pull in externally gathered data to make smarter decisions about what network traffic to allow and what traffic to block.Now just one indespensible element in an ecosystem of network defenses, the latest versions are known as enterprise firewalls or next-generation firewalls (NGFW) to indicate who should use them and that they are continually adding functionality.What is a firewall? A firewall is a network device that monitors packets going in and out of networks and blocks or allows them according to rules that have been set up to define what traffic is permissible and what traffic isn’t.To read this article in full, please click here

How SD-WAN can improve your security strategy

Data breaches and security threats are a top concern among IT leaders, yet it’s harder than ever to hire skilled security professionals. That has organizations looking for ways to more easily improve their security strategy. One option is to implement a software-defined WAN (SD-WAN).I recently talked with Hamza Seqqat, director of solutions architecture at Apcela, to get his take on how SD-WAN affects security strategy. Seqqat helps enterprise organizations redefine their wide-area networks to accommodate the growing use of cloud-based applications and services. In our discussion, he outlined four areas where SD-WAN offers new security benefits.To read this article in full, please click here

Batten down the DNS hatches as attackers strike Feds

If enterprise IT folks haven’t taken a look at their DNS ecosystem recently now may be a good time. This week the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) told all federal agencies to bolt down their Domain Name System in the face of a  series of global hacking campaigns.

Cisco patches serious SD-WAN software security holes

Cisco has patched security vulnerabilities in four packages of SD-WAN Solution software that address buffer overflow, arbitrary file override and privilege access weaknesses that could have led to denial-of-service attacks or access problems.The first patch, called “Critical” by Cisco, fixes a vulnerability in the vContainer of the Cisco SD-WAN Solution that could let an authenticated, remote attacker cause a denial of service (DoS) and execute arbitrary code as the root user, the company wrote in a security advisory. To read this article in full, please click here

Durham County goes Cisco for enterprise network ops and security proficiency

The IT department in Durham County, N.C.'s government was spending far too much time manually addressing network and security operations and turned to Cisco to help achieve the operational and security effectiveness it was looking for.The government in Durham County, N.C., was spending hours and hours manually provisioning its network and keeping security policies current, so it decided two-and-a-half years ago to upgrade for the sake of efficiency and security.Since then, the government’s IT staff of four has migrated its traditional point-to-point network to a more modern enterprise featuring the software-defined technologies of Cisco’s Application Centric Infrastructure (ACI) and DNA Center that support its 2,100 enterprise end-users and online services for 315,000 county residents. To read this article in full, please click here(Insider Story)

Quantum-embedded chips could secure IoT

Microprocessors that are unique to each Internet of Things (IoT) device is the way forward in the ongoing and tricky quest to secure the IoT, says Crypto Quantique. One idea is that by making each chip one of a kind and unclonable, an application would become almost impossible to hack.The U.K.-based startup says it has introduced “the world's most advanced security product for IoT devices.” The microprocessor-based solution uses quantum physics, combined with cryptography, all embedded in silicon, it explained in a press release last October.To read this article in full, please click here

Top 10 IoT vulnerabilities

Security questions have dogged the Internet of Things (IoT) since before the name was invented. Everyone from vendors to enterprise users to consumers is concerned that their fancy new IoT devices and systems could be compromised. The problem is actually worse than that, as vulnerable IoT devices can be hacked and harnessed into giant botnets that threaten even properly secured networks.But what exactly are the biggest problems and vulnerabilities to avoid when building, deploying, or managing IoT systems? And, more to the point, what can we do to mitigate these issues?To read this article in full, please click here

First step to becoming a hacker: Linux!

If you're contemplating a career in cybersecurity and haven't come up to speed on Linux, now's the time to get ramped up and here's one easy way to do it. This new book from no starch press was written with people like you in mind. Authored by OccupyTheWeb, the force behind Hackers-Arise, Linux Basics for Hackers provides everything from basic Linux command line skills through to scripting, manipulating logging, network scanning, using and abusing system services, and remaining stealthy in the process.Why Linux? Because Linux is open source, tool developers (and you) have a level of access that is unsurpassed. Linux is transparent and this means that you can learn to manipulate it in ways that are not possible with most OSes. In addition (and undoubtedly for the reason just mentioned), most cybersecurity tools are written to run on Linux.To read this article in full, please click here
