MITRE ATT&CK is a free, open knowledge base of the tactics and techniques used by real world cyber adversaries. It is not a product or a standard but a common language that red teams, blue teams, threat intelligence and SOCs all share. We explain its structure (tactics, techniques, sub-techniques), how to use it for threat informed defense, and how it differs from the Cyber Kill Chain, with sources.
Read moreOT is the technology that controls a factory's, power plant's or water treatment facility's physical processes, and ICS and SCADA are its most common forms. A cyber attack here is not just data loss, it can mean production stoppage, equipment damage or a safety risk. We explain the Purdue model, insecure legacy protocols like Modbus and DNP3, asset visibility and IEC 62443 based defense, with sources.
Read moreContainers and Kubernetes have become the standard way to run modern applications fast and at scale, but that speed often lets security slip through. Image scanning, non root runtime, Kubernetes RBAC and network policies, and secrets management. We explain container and Kubernetes security across four layers, with a checklist and sources.
Read moreA supply chain attack hits you not directly but through a third party you trust, a software library, an update server, a supplier or a service provider. One successful compromise can affect thousands of organizations at once. We explain what supply chain attacks are, their forms, why traditional defenses miss them, and how to defend with SBOM, dependency scanning, provenance and vendor risk management, with sources.
Read moreRAG is the most powerful way to run an AI model with your organization's own documents, but this knowledge base and the vector database that holds it are a new, often overlooked attack surface. Indirect prompt injection through documents, knowledge base poisoning, embedding privacy and access control issues. We explain RAG and vector database security, the threats and the defense, with sources.
Read moreAn AI model is only as good as the data it learned from, and an attacker can corrupt the model from the inside by poisoning that data. Data poisoning, backdoor insertion, model theft and adversarial examples are a new attack class specific to AI. We explain how these attacks work, their real risks and how to defend with data provenance, red teaming and monitoring, with MITRE ATLAS and OWASP references.
Read moreRunning a language model on your own server instead of the cloud preserves privacy and ends API dependency. But how is it done? The hardware needed, local runtime tools like Ollama, open models (Llama, DeepSeek, Mistral), quantization, RAG on your own documents and securing the local model. A practical, sourced local LLM setup guide for organizations.
Read moreYour employees may be pasting customer data, source code and contracts into cloud based AI tools to speed up their work. This is called Shadow AI and it is one of the biggest unnoticed data leakage channels. We explain what Shadow AI is, how data leaks, the KVKK risk, and how to solve it with a local model and a usage policy rather than a ban, with sources.
Read moreCloud based AI is powerful, but it sends every query, code and piece of data to another company's server. In work that requires security and privacy this is unacceptable. Local (offline) AI runs models on your own hardware, giving the power of AI without the data ever leaving. We explain what local AI is, why it is critical for data sovereignty and KVKK, and why DSET's KAOS engine runs fully local, with sources.
Read moreIf you have lost data in Istanbul, whether a business server, a personal laptop or a phone, the first rule is not to touch the device and not to keep powering it. We explain the whole data recovery process, failure types and how to choose the right service for individuals and companies in Istanbul, with our cargo flow to the Ankara Hacettepe Teknokent lab, cleanroom and PC-3000 hardware, a free diagnosis and a no data no fee approach.
Read moreBefore an attacker attacks your company, they collect every piece of information exposed about you on the internet, open ports, forgotten subdomains, leaked employee emails, exposed panels and social media traces. This is called the external attack surface and OSINT. We explain how the attacker sees you, what information leaks and how to narrow your attack surface, with sources.
Read moreThe password you signed up to a site with ends up in attackers' hands when that site is breached. If you used the same password elsewhere, attackers try it on your other accounts with automated tools, this is called credential stuffing. We explain where leaked passwords come from, how accounts are taken over automatically, and how to protect yourself with unique passwords, 2FA and passkeys, with sources.
