Ever since CVE-2022-2274, didn’t reach Heartbleed levels of ick, but it was more than bad enough.
What happened was that the OpenSSL 3.0.4 release introduced a serious RSA bug in X86-64 CPUs supporting the AVX512 IFMA instructions. This set of CPU single instruction, multiple data (SIMD) instructions for floating-point operations per second (FLOPS) was introduced in 2018. You’ll find it in pretty much every serious Intel processor, from Skylake to AMD’s forthcoming Zen 4. In other words, it’s probably in every server you’re currently running.
Is that great news or what?
Memory Corruption
The problem is that RSA 2048-bit private key implementations fail on this chip architecture. Adding insult to injury, memory corruption results during the computation. The last straw? An attacker can use this memory corruption to trigger a remote code execution (RCE) on the machine.
Exploiting it might not be easy, but it is doable. And, even if an attack isn’t that reliable, if it’s used to hit a server that constantly respawns, say a web server, it Continue reading

Networks are so vital because they enable business, human and mission-critical processes by connecting organizations with customers, employees and partners, increasing efficiency, powering automation, driving engagement and accelerating productivity. Networks are the glue that knit modern applications together.
But apps can only be as available and fast as the network that underpins them. Achieving high levels of reliability and speed are keys to success. Network disruptions and slowness are a daily reality that lead to downtime with Starlink.

Here a security hole, there a security hole, everywhere a security hole. One of the latest is an obnoxious one labeled Apache HTTP Server‘s CVE-2022-23943, an Apache memory corruption vulnerability in mod_sed, was uncovered. This one was an out-of-bounds Write vulnerability that enabled attackers to overwrite heap memory. When you say, “overwrite heap memory,” you know it’s bad news. This impacted the Apache HTTP Server 2.4 version 2.4.52 and earlier versions.
New Problems
It was quickly fixed. But, JFrog Security Research team’s Security Research Tech Lead, worried that while the
Tailscale SSH, which simplifies authentication and authorization by replacing SSH keys with the Tailscale identity of any machine.
A Secure Shell or SSH key is an access credential in the SSH.COM.
Tailscale gives each server and user device its own identity and node key for authenticating and encrypting the Tailscale network connection and uses access control lists defined in code for authorizing connections, making it a natural extension for Tailscale to now manage access for SSH connections in your network.
Removes the Pain
“SSH is an everyday tool for developers, but managing SSH keys for a server isn’t so simple or secure,” said Tailscale Product Manager
According to the Fortinet vArmour senior vice president. “This enables organizations to not have to in essence boil the ocean and try and adopt unilateral controls too quickly, but instead lock down their crown jewels and understand the relationships those assets have to address resilience planning in a phased approach.”
One of the biggest mistakes we see when implementing zero trust is insufficient investing in visibility, observability, and analytics across the organization, Kuehn added. “Without visibility, companies are limited Continue reading
Zero Trust Architecture (ZTA) builds on the foundational principles of zero trust security as defined by the National Institute of Standards and Technology (NIST) in publication Ansible, Puppet, and Crowdstrike offer products that cover the entire spectrum of detecting and protecting endpoints within a corporate network. This would include everything from antivirus and antimalware to abnormal network activity monitoring. Microsoft, Trend Micro, and SentinelOne offer similar capabilities and made Gartner’s upper quadrant in their 2021 Endpoint Protection report.
Wrap up Zero Trust Architecture
The real answer to the question of what is zero trust architecture depends on your most important corporate assets. Any network design should also include consideration of the humans with access to those critical assets. Trust but verify applies to corporate employees as well as geopolitical relationships.
Choosing the right vendors and partners to meet your specific objectives will help you implement a solid Zero Trust Architecture. Once implemented it comes down to diligence and persistence. New threats pop up regularly and must be met with an adaptive security posture. Those who don’t adapt and change will be doomed to failure.

Tackling the challenge of providing fast, smooth, jitter-free gameplay with super low end-to-end latency, social media giant in a blog post Thursday.
This low-latency gaming platform could also serve as the base Meta’s pending Metaverse, they asserted.
Facebook launched its cloud gaming platform in 2020, providing users quick access to native Android and Windows mobile games across all the browsers. Along with high a volume of consumer access came a high volume of developer and engineering challenges.
Network, Hosting, and Cluster Management
The first step Meta took in providing low end-to-end latency was a physical one — to reduce the distance between the cloud gaming infrastructure and the players themselves. For this Meta used edge computing and deployed in edges that were close to large populations of players. The goal of edge computing is to “have a unified hosting environment to make sure we can run as many games as possible as smoothly as possible,” Meta engineers Xiaoxing Zhu wrote.
The more edge computing sites, the lower the user latency.

As cyberattacks continue to escalate; companies grow their use of tech services outside of their network perimeters and the government and other organizations work with ever more sensitive personal, corporate, and government data, there is increasing adoption of zero trust data protection.
So, What Is Zero Trust Data Protection?
Zero trust data protection is a security methodology that includes a framework of technologies and best practices that an organization needs to define and adopt across their IT environments over time, explained Steve Malone, Sumo Logic director of security product. “It’s the culmination of something that’s been happening in security over the last 20 years, which is the perimeter is not the point of enforcement anymore because of the way that technology works today.”
Interest in operating in a zero trust data protection environment has gained plenty of interest in the last few years, according to Michael Gorelik,

Modern, cloud-based, distributed networks may lack a defined perimeter to protect, but they still need network security. And nearly all organizations know that:
In the first article in this series, we discussed what zero trust security is and why it matters. In this article, we will take a deep dive into zero trust network access, how it works, and its benefits to the modern organization.
What Is Zero Trust Network Access?
Zero Trust Network Access, or ZTNA, is a security solution that many IT departments and IT organizations use to ensure secure remote access to a range of data, applications, networks, and services within an organization. ZTNA is based on defined access control policies that clearly communicate who has access to what and for how long that access is granted.
ZTNA is a gap-filler when it comes to secure remote access tools, methods, and technologies. VPNs or virtual private networks are different from zero trust network access because VPNs give access to an entire network rather than specific applications or data. As the remote workforce continues to take shape and many companies lean on it as a source of employee satisfaction and employer productivity. Zero trust network access is pertinent to keeping the right people in and the wrong people out of your organization’s systems.
