Only 22 percent of organizations treat AI agents as independent, identity-bearing entities, while 88 percent have already dealt with suspected or confirmed security incidents involving AI agents. Ninety percent of AI usage occurs through unauthorized personal accounts, with an average of 223 shadow AI incidents per month.
Building security into the framework of an organization prevents security from being seen as a barrier to daily activities. If an employee feels as if a security measure is inhibiting them from completing their daily tasks, they're far more likely to find a way around that measure. This can range from propping open a door to using the same easy-to-remember password for every account.
We have already discussed in the previous two articles about file and folder permissions along with special permissions that are supported in linux. The permissions are effective for many scenarios. But what happens when you need more granularity? How do you grant write access to a file to just one specific user who isn't the owner and isn't in the owning group? How do you allow two different groups read access, but only one of them write access?
These freezers operate under extreme thermal and electrical conditions. Exposure to subzero environments, high-powered compressors, and sensitive control systems creates risks that demand structured procedures. Facilities that rely on equipment like a freezer -40C, must apply disciplined handling standards to protect both staff and stored materials.

In 2025, nearly every security conversation circled back to AI. In 2026, the center of gravity will shift from raw innovation to governance. DevOps teams that rushed to ship AI capabilities are now on the hook for how those systems behave, what they can reach, and how quickly they can be contained when something goes wrong. At the same time, observability, compliance, and risk are converging.
When he got notified of exceeding the limit, he wandered off to his user settings and found out he could simply change the organization's budget limitations (to over $1M!) - even though he wasn't the admin. The admin received no notification.
Linux enforces a powerful permission model designed for multi-user security, access isolation, and resource governance. Whether you are an SRE, DevOps engineer, or a systems programmer, mastering Linux permissions is fundamental for secure and reliable operations. In this deep dive, we'll break down the basic permission system with practical examples. Permission Types in Linux Linux defines three access types: read:
In broad strokes, Serval is using agentic AI models to automate IT service management, but the company has a unique approach that takes advantage of agentic AI's powers while avoiding many of its pitfalls. One agent is used to code internal automations for everyday tasks like authorizing software or provisioning a device. The founders see it as a kind of vibe-coding tool, overseen by an IT manager, but doing most of the work on its own.
Who controls the data? Every meeting should be captured, but not every recording needs to be shared. Use private meeting settings, control access permissions, and set retention policies that auto-delete after a certain number of days. Who needs access? The power of AI is capturing everything. The responsibility is controlling who sees what. Share broadly for team updates, narrowly for performance reviews, not at all for sensitive discussions.
Security guards patrol areas that used to feel universally safe. This shift reflects a hard truth about modern healthcare - the environments designed for healing have become unexpectedly dangerous places to work. Behind every access control system, every badge scan, every visitor check-in, there are real people trying to do their jobs while feeling safe. And right now, too many of them don't.
Multi-tenant authorization effectively manages user permissions across accounts, ensuring that each tenant operates within its own isolated environment and has tailored access controls.
Amazon Cognito simplifies user sign-up and sign-in for applications, enhancing security with features like JWTs and access token customization for diverse use cases.
