Ensuring Your Privacy: The Critical Role of Security in Choosing a VPN

Among the growing digital threats to privacy, picking out a Virtual Private Network with the right security features makes it very fundamental. The VPN will not only hide your IP address but will go ahead and encrypt your internet connection, thus helping maintain your privacy while online. On the other hand, not all VPNs are created equal. When it comes to the question of what security in a VPN is, it can enable one to make-without question-an informed decision towards guarding one's digital life.

How a Network Digital Twin Prevents Change-Related Outages

In today's rapidly evolving IT landscape, effective change management is crucial for maintaining network stability and performance, but many organizations lack a consistent change process. Lack of process often leads to unintended consequences, such as outages and performance degradation. A network digital twin offers a transformative solution to these challenges by streamlining change management processes and providing pre- and post-change verification to enhance operational efficiency.

New NIST Zero Trust Guidance Reinforces Agent Hygiene Value

This week, the National Institute for Standards and Technology (NIST) released “Implementing a Zero Trust Architecture (NIST SP 1800-35)” for public comment. The guide is written by NIST’s National Cybersecurity Center of Excellence (NCCoE) in collaboration with 24 cybersecurity companies. Now in its fourth draft, NCCoE has opened up comments for this Zero Trust Architecture (ZTA) guide through Sept. 30, 2024, as part of a 60-day review cycle.

Firmware Vulnerabilities Run Rampant in Cellular Routers

The current state of OT/IOT security is being repainted with a new coat of risk. The shade of color? Cellular routers and the vulnerabilities within firmware. In our new report with Finite State, our joint research explores the risks organizations face within the software supply chains of OT/IoT routers. Hardware has firmware – operational software – within its memory components.

Corelight Announces Cloud Enrichment for AWS, GCP, and Azure

This week, I’m excited to announce Cloud Enrichment for AWS, GCP, and Azure. These enhancements are designed to accelerate incident response and unlock threat hunting capabilities by automatically combining the insights of your cloud network with the native control plane data from your cloud service provider.

The Importance of Firewall Logs

A firewall is a crucial network security element that forms a barrier between an internal network (e.g. a company's intranet) and external networks (e.g. the Internet). A firewall's main objective is to regulate and monitor incoming and outgoing network traffic based on prescribed rules. This helps prevent unauthorized access, safeguards sensitive data, and mitigates security risks.

ICS Malware 'FrostyGoop/BUSTLEBERM': Insights Others Missed

In the last few weeks, there have been a few announcements made about a new malware threat known as FrostyGoop or BUSTLEBERM (as it was originally tracked by Mandiant). It is being recognized as the first custom malware to integrate Modbus for the purpose of causing physical damage. An associated incident has been reported where the malware was used to disrupt heating in Ukrainian homes in the context of a Russian cyberattack.

Decoding Networks: The Revolutionary Impact of Mapping Tools

In today's hyper-connected world, unraveling the complex tapestry of relationships within various systems has become crucial. Enter the network mapping tool - a game-changing innovation empowering professionals across industries to visualize, dissect, and enhance intricate networks.

Common Types of Network Devices and Their Functions

Modern IT infrastructure is comprised of various interconnected network components that make communication and resource sharing possible throughout your organization. Whether securing sensitive data, facilitating collaboration, or simply ensuring uninterrupted access, a network of devices is at play—and the elements of these devices are critical to a business’s successful operation.
