Differential Backup vs. Full Backup: How to Choose

TL;DR: A full backup copies all data in a single self-contained set for the fastest restore, while a differential captures everything that changed since the last full backup, cutting daily backup time and storage but requiring two sets to recover. The differential backup vs. full backup choice comes down to data size, change rate, and RTO/RPO targets.

AI transformation means reaching the point of no return

There’s a simple way to know when technology has been truly transformative. It’s when your work would fall apart if you took it away. Think about electricity, the internet, personal computers — we’re pathetically helpless when they break, and we’d struggle to redesign work without them. Very few teams have reached this point with AI. Software engineers are the exception — AI has radically changed how they build and ship software.

Stopping an Intrusion Doesn't Mean the Incident Is Over

When unauthorized access is detected and blocked, the threat might seem contained. But locking the attacker out doesn't answer the most critical questions: What did they do before they were discovered? What did they access? Were they able to exfiltrate data? This is what happened in the recent cyberattack on France's General Directorate of Public Finances. In late June, the agency detected multiple instances of unauthorized access during a routine check and immediately shut them down.

Nvidia Brev Security Breach: SSH Keys for Customer VMs Exposed

Nvidia disclosed in early November that its Brev cloud development platform experienced a security incident with unauthorized activity spanning October 4 through October 20, 2026. Brev is the GPU-instance platform Nvidia acquired from Brev.dev in July 2024, used by developers to spin up on-demand cloud GPU compute for AI and ML workloads.

ML-KEM vs ML-DSA vs SLH-DSA: Which Is Best for Post-Quantum Signatures?

RSA and ECC are geared toward the day quantum computers arrive, and the industry is trying to get ahead of the curve. NIST has adopted three algorithms for key establishment (ML-KEM), ML-DSA, and SLH-DSA for signatures. NIST has recently completed three post-quantum standards that will help keep systems secure when quantum computers can break RSA/ECS encryption. ML-KEM is used for setting up shared secrets via key encapsulation and is not a signature algorithm.

Critical vulnerability: OpenSSH authentication bypass on Alpine Linux (CVE-2026-123158)

On November 5, 2026, Alpine Linux published a security advisory for an authentication bypass in its openssh-server package, nicknamed sshole by researcher Özgün Kültekin of Wakefield, who reported it. An attacker who can reach the SSH port can log in to accounts that have no password set, such as key-only users, without knowing any password. Every Alpine release from 3.16 through 3.24 and edge is affected. No CVE identifier has been assigned yet. Fixed packages are available.

Agentic AI Security: The Risks Every Business Must Know | Erich Kron (KnowBe4)

AI agents don't just answer questions; they take action. And when an AI agent gets bad information, a wrong answer can quickly become a security incident. In this 403 Circle webinar powered by Astra Security, Erich Kron (CISO Advisor at KnowBe4, 30 years in cybersecurity, former Security Manager of the U.S. Army's Second Regional Cyber Center) breaks down why agentic AI is going to change the way we do business and what security leaders need to do before handing autonomous AI agents the keys.

What Happens if You're Injured in an Accident While Driving a Company-Owned Vehicle?

Being involved in any type of automobile crash can be a very stressful experience. This situation becomes significantly more stressful when you were in a crash while driving a company-owned vehicle. Whether you're a delivery driver or were just running an errand, this type of accident presents some complex legal challenges and insurance considerations.
