Cum obții un certificat SSL gratuit pentru o adresă IP publică cu Let’s Encrypt

În mod normal, pentru a securiza un server web cu HTTPS folosind Let’s Encrypt avem nevoie de un nume de domeniu asociat serverului.

Începând cu 2026, Let’s Encrypt permite însă emiterea certificatelor SSL/TLS și direct pentru adrese IP publice, atât IPv4, cât și IPv6. Astfel, putem avea o conexiune HTTPS validă chiar dacă accesăm serverul direct prin IP și nu avem un domeniu configurat. Această funcționalitate poate fi utilă pentru servere VPS, servicii de test, infrastructură cloud, servere temporare sau diferite servicii self-hosted.

Spyware-ul pe înțelesul tuturor: cum îl eviți?

Spyware-ul este un tip de program rău intenționat care îți poate urmări activitatea pe telefon, laptop sau calculator fără ca tu să îți dai seama. Poate colecta parole, conversații, istoricul de navigare, locația, date bancare sau alte informații personale. De multe ori, spyware-ul nu se manifestă evident, tocmai pentru că scopul lui este să stea ascuns cât mai mult timp.

7 Practical ways to repurpose your old Android Phone

Most people have at least one old Android phone sitting in a drawer. Maybe the battery is weaker than it used to be, maybe the camera is outdated, or maybe it no longer receives major software updates. That does not mean it is useless.

As long as the phone still turns on, connects to Wi-Fi, and can run basic apps, it can still serve a practical role around the house, in the car, or next to your main PC. The original article focused on Motorola phones, but most of the same ideas work for almost any Android device.

How security Professionals can actually use LLMs effectively

Large language models (LLMs) like ChatGPT, Claude, and development tools such as Cursor have quickly become part of many engineering and security workflows. Yet many security professionals still struggle to get meaningful results from them. The problem is rarely the tool itself. It is usually how the tool is being used.

Many people interact with LLMs the same way they use search engines: short queries, minimal context, and the expectation of a quick answer. That approach works poorly for complex security work. Security analysis depends on context, constraints, systems thinking, and domain knowledge. Without those elements, the model will default to generic answers.

Used properly, however, LLMs can accelerate research, system design, documentation, threat analysis, and engineering tasks. The following techniques outline practical ways security analysts, threat hunters, SOC analysts, and security engineers can structure their prompts to get much higher-quality output.

Tailscale: The Easiest way to access your Homelab from Anywhere

If you’ve ever tried to access your homelab, NAS, or Proxmox server from outside your house, you probably know the pain. Open ports on the router, deal with NAT, hope your ISP didn’t throw you behind CG-NAT, and then sit there wondering how exposed your services really are.

On top of that, you have to think about dynamic IPs, firewall rules, and whether you just made your setup visible to the whole internet.

Kaspersky Antivirus vs Bitdefender: which one should you choose in 2026

Choosing an antivirus today is less about flashy features and more about trust, performance, and how much it gets in your way. Two names come up again and again when people talk about serious protection: Kaspersky and Bitdefender.

Both are well-known, both score highly in independent tests, and both have been around long enough to prove they are not experiments. Still, they feel very different when you actually use them.

Windows 10 Support is Ending — Here’s how to keep getting Security Updates

On October 14, 2025, Microsoft will officially stop supporting Windows 10. That means no more feature updates, bug fixes, or security patches — unless you enroll in the Extended Security Updates (ESU) program. The ESU gives you one extra year of security updates, extending protection until October 13, 2026.

If you’re not ready to move to Windows 11 yet, here’s how to qualify and sign up.
