DARPA explores new computer architectures to fix security between systems

Solutions are needed to replace the archaic air-gapping of computers used to isolate and protect sensitive defense information, the U.S. Government has decided. Air-gapping, used often now, is the practice of physically isolating data-storing computers from other systems, computers, and networks. It theoretically can’t be compromised because there is nothing between the machines — there are no links into the machines; they’re removed.However, many say air-gapping is no longer practical, as the cloud and internet takes a hold of massive swaths of data and communications.“Keeping a system completely disconnected from all means of information transfer is an unrealistic security tactic,” says Defense Advanced Research Projects Agency (DARPA) on its website, announcing an initiative to develop completely new hardware and software that will allow defense communications to take place securely among myriad existing systems, networks, and security protocols.To read this article in full, please click here READ MORE HERE…

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 READ MORE 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 READ MORE 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 READ MORE HERE…

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.
