With the recent discovery of a significant Chrome vulnerability tagged as CVE-2025-0762, Google Chrome has again come under fire. This new threat, found in the DevTools function of the browser, is a use-after-free memory issue, which opens the door for potential attackers to execute arbitrary code, thereby compromising system security. Given Chrome’s ubiquitous presence across various platforms, the urgency to update Chrome to version 132.0.6834.159 cannot be overstated.

A Linux Admins Guide to Ensuring Data Privacy in 2025

A Linux Admin's Guide to Ensuring Data Privacy in 2025

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

In 2025, we Linux security admins face new challenges brought on by growing data privacy concerns that demand increased attention to detail and strict compliance. The rise of biometric security—a powerful tool for authentication—also brings significant risks if not managed correctly. Look no further than the high-profile troubles of Bunnings Group and White Castle, where failures in obtaining explicit user consent for biometric data collection led to legal and financial repercussions. Ensuring transparent, consent-based data collection practices is key to avoiding similar pitfalls.

With the support of the open-source community and a strict privilege system embedded in its architecture, Linux has security built into its design. That being said, gone are the days when Linux system administrators could get away with subpar security practices. Cybercriminals have come to view Linux as a viable attack target due to its growing popularity, the valuable devices it powers worldwide, and an array of dangerous new Linux malware variants that have emerged in recent years.

Migrating from .NET Framework to .NET Core: Security and Open Source Benefits

Migrating from .NET Framework to .NET Core: Security and Open Source Benefits

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

As organizations look to modernize their applications and increase performance, .NET Core can be a pivotal shift from the .NET Framework. It is the perfect platform to build secure, scalable, and future-ready solutions, with a growing emphasis on open-source technologies and cross-platform compatibility. In this article, we explore the migration process and how using Linux and open source can make it more secure and efficient before and after the migration.

Linux vs. Viruses: The Power of User Savvy & System Architecture

Linux vs. Viruses: The Power of User Savvy & System Architecture

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

As a Linux security admin, you've likely spent countless hours fine-tuning your systems' defenses, but here's a reality check: Linux's inherent safety isn't just about firewalls and kernel updates. Often, the savvy users themselves serve as a frontline defense against malware. Unlike their Windows and macOS counterparts, Linux users tend to have a deeper understanding of their operating systems, enabling them to identify and avoid suspicious activity before it becomes a threat. This user knowledge cultivates a proactive approach to security that bridges the gap traditional measures might miss.

Agility and scalability are paramount for us Linux security admins, and traditional software deployment methods often fall short in these critical areas. Container technology is a game-changing innovation that has revolutionized how software is deployed, managed, and scaled. It offers many benefits to ensure that applications run consistently regardless of the hosting environment.

Balancing Security with Transparency in Open-Source AI

Balancing Security with Transparency in Open-Source AI

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Open-source AI offers many opportunities, including high levels of innovation, while also presenting security admins with unique challenges. Leaders in AI, such as Clem Delangue from Hugging Face and Rahul Roy-Chowdhury from Grammarly, stress the significance of transparency and ethical decision-making when building trustworthy AI systems. Delangue advocates for greater transparency even at the expense of performance, while Roy-Chowdhury notes how open-source AI provides transparency for otherwise opaque systems that would otherwise remain hidden and untrustworthy.

As more vendors, suppliers, and contractors become integral to an organization's operation, the need to identify and mitigate risks associated with such external partners is significant. Third-party risk management automation (TPRM) is essential in this process. TPRM involves integrating technology that streamlines and automates various methods for identifying, assessing, and mitigating risks from external partners.
