A popular endpoint security strategy for users who have access to important data is to implement a physical air gap, also known as “Privileged Access Workstations” (PAW) or “Secure Access Workstations” (SAW). With PAWs, each end user has a separate laptop or desktop that is dedicated solely to sensitive tasks and information. These devices are […]
We all know that organizations going through the digital transformation revolution have to navigate significant technology, culture and workflow challenges. What’s becoming increasingly clear is that, as more of their business becomes digitized, they’re increasingly facing three major user-related challenges that can’t be ignored and require radical new approaches. In this first of a two-part […]
For over 2,000 years, people have leveraged elevated terrain, or “high ground,” to gain a strategic advantage over enemies and protect their realm. The Chinese “Art of War” suggests high ground as a strategic position that provides a wide point of view with full visibility over the landscape. In medieval Europe, castles and fortresses included […]
From app sandboxing to OS isolation: How the endpoint is evolving Last week, HP announced that it has acquired Bromium, maker of an app sandboxing product that uses virtual machines (VMs) to sandbox specific applications, such as browsers and office apps. This acquisition marks another important milestone in the evolution of endpoint isolation technologies. […]
Authentication solutions have been around for years. I actually started my cyber career working on one of the original and best two-factor (2FA) products – SecurID. Over the decades, the tech we use, the way we communicate and connect, and the threats we face have changed dramatically. So has authentication. 2FA is now MFA – […]
As a systems administrator, it has always been a difficult struggle to balance Microsoft User Rights Assignments in the Windows Operating System. Too much access on a file system is dangerous, while not enough causes subsequent tickets created at a help-desk. An equilibrium of supportability and security is ideal, yet seldom achieved. Windows Local Administrator […]
The end of the Windows 7 lifecycle is fast approaching: January 2020. This pending “end of life” means Microsoft will discontinue all support, including paid support, and all updates, including security updates. Of course, Microsoft might make an exception for some of its larger customers, but at a heavy price. What does this mean for […]
Isolation is an increasingly popular endpoint security strategy, and with good reason. It reduces risk by separating endpoint attack vectors from cyber criminals. Browser isolation is one of several isolation approaches. (Application, virtual and physical air gaps and virtual desktop infrastructure/VDI are others). Its concept is simple: move Internet activity away from a company’s local networks […]
Many IT organizations use app sandboxing in an attempt to safeguard sensitive information from cybercriminals. It’s a pretty straight-forward concept: contain threats coming from the sandboxed application to prevent them from affecting the OS. Kind of like making sure your kids can’t track sand from their outside sandbox into your house, where it would keep […]
Network Isolation, the segmenting of a computer network into separate zones with distinct trust levels, for the purpose of containing hazards or reducing damage caused by a threat actor, is a hallmark of nearly every security-minded network design. Even though implementing port security policies, VLANs, VPNs, and other technologies can take many months of planning […]
I’m excited to be starting a new journey as CEO of Hysolate. I first met Tal Zamir, Hysolate’s Founder, two and a half years ago when he was just getting started with Hysolate. He presented this grand vision of splitting up people’s laptops into multiple, totally isolated and virtualized operating systems but unifying them into […]
When considering endpoint security strategies, it’s incredibly common to have an endpoint protection platform (EPP) in place. Let’s face it – Anti-virus (AV) is the OG endpoint security solution. Over the years, these tools have evolved into next generation antivirus (NGAV) and endpoint detection and response (EDR). What that really means is that vendors have […]
I hate airport security. The endless lines. Taking off your shoes. And your jacket. And your belt. Pulling all of your gadgets / laptops / tablets out of your bag, throwing away your toothpaste because it’s oversized, being scanned by mysterious scanners, being patted-down by strangers, answering security questions about your visit at 6AM after […]
Could it be used to compromise your corporate environment? This week a vulnerability in the messaging app WhatsApp was reported that has allowed attackers to inject commercial spyware on to phones. WhatsApp, which is used by 1.5 billion people worldwide, discovered in early May that attackers were able to install surveillance software on to both […]
Anyone who’s been in enterprise IT long enough has already heard of, tested or deployed virtual desktop infrastructure (VDI). And why not? The promises made by VDI vendors have been compelling, if not always accurate: cost savings, enabling bring your own device (BYOD), improving the user experience and business continuity, amongst others. However, there is […]
Microsoft’s recent security patches, released on “Patch Tuesday,” reveal more vulnerabilities with Windows Dynamic Host Configuration Protocol (DHCP). Here’s what they imply and how Hysolate protects against them. Quick Summary: Of the 64 bugs squashed in Redmond’s March update, three caught our eyes: CVE-2019-0697, CVE-2019-0698, and CVE-2019-0726, all of which address holes in the DHCP […]
For a number of reasons, I’m pretty excited about the Privileged Access Workstation (PAW) Survey conducted by Cybersecurity Insiders. First – there seems to be a resounding agreement that IT admins need to use separate operating systems for sensitive and corporate activities. Nearly all respondents (94%) agree that IT admins are at increased risk of […]
CISOs and security professionals often refer to Virtual Desktop Infrastructure (VDI) and other “remote application” solutions as security barriers that hackers have a hard time bypassing. That’s a myth, and here’s why. Thin client scenarios are precarious. These uses of VDI pose only a minor hurdle to determined cyber-criminals. An employee using a thin client […]
It’s been a week since Cybertech 2019, and while the event made headlines for some of its famous speakers, most notably Benjamin Netanyahu, it held great importance for Hysolate for many more reasons. Our co-founder and CEO, Tal Zamir, had the opportunity to speak on a panel with fellow Team 8 co-founders Ofer Israeli, Illusive, […]
In recent years, enterprises have started to become much more aware of the importance of IT hygiene for privileged accounts. With so many public cases of hackers gaining access to critical resources and causing insurmountable damage, it’s hard to escape the reality of today’s ever-increasing cyberattacks. One prominent example is the attack on the Ukrainian […]
