Its final goal is to improve security practices and, through that, to find, fix and preferably prevent security issues within applications. It encompasses the whole application life cycle from requirements analysis, design, implementation, verification as well as maintenance <!– more –> Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. https://dornea.nu/service/secure-software-engineering/ Mon, 23 May 2022 14:32:43 +0200 https://dornea.nu/service/secure-software-engineering/ Following the principle of security and privacy by design, the Secure Software Engineering Group thrives to support software developers in designing and implementing software systems that are known upfront to be secure with respect to certain attack vectors. Opposed to offensive approaches to software security, like ethical hacking, our group specializes on constructive techniques for software security. Our recipe to success is a unique novel combination of program synthesis and analysis techniques https://dornea.nu/service/pkms/ Wed, 26 Feb 2025 06:54:44 +0100 https://dornea.nu/service/pkms/ Personal knowledge management (PKM) is a systematic process of collecting information that a person uses to gather, classify, store, search, retrieve, and share knowledge in their daily activities. It’s a response to the idea that knowledge workers need to be responsible for their own growth and learning in an era of information overload. My PKMS Journey My journey with knowledge management began over a decade ago when I was overwhelmed with information from multiple sources - books, articles, work documentation, and personal research. https://dornea.nu/service/golang/ Wed, 26 Feb 2025 06:37:15 +0100 https://dornea.nu/service/golang/ Securing modern web applications while ensuring seamless deployment and continous integration is critical. I’ve been leveraging Golang’s capabilities for a while now to build secure and scalable solutions. Go is known for its simplicity, efficiency and but also for strong support for cross-platform compatibility. By combining DevOps best practices and cybersecurity you’ll get DevSecOps, which offers a unique approach to securing applications throughout the entire development lifecycle: From deployment strategies to monitoring and maintenance. https://dornea.nu/cv/skills/ Wed, 29 Nov 2023 15:16:18 +0100 https://dornea.nu/cv/skills/ Programming languages Lang Examples Proficiency Golang ★★★★★ gocial aws-custom-resource-golang access-key-rotator widdly tw5-cli Python ★★★★★ smalisca netgrafio crudappify appvulnms icmpknock C ★★★ ixkeylog rsachat x86 ASM ★★★ Java ★★ Elisp ★★ DevSecOps Cloud Computing Serverless AWS Lambda Frameworks serverless. https://dornea.nu/cv/activities/ Tue, 11 Feb 2025 06:51:38 +0100 https://dornea.nu/cv/activities/ 2025 2024 Setup defersec.com where I write about Golang & DevSecOps I’ve left Cashlink and joined SAP as a Development Expert for Security At SAP I started contributing to OSS (heureka, barbican) My article on Golang debugging in Emacs was featured in Golang Weekly I’ve started learning how to play Congas 🪘 Read my 2024 review 2023 Played with AWS custom resources in Golang Started my Documentation as Code for Cloud series Learned some terraform Learned about Kubernetes (and especially EKS) basics Attended the AWS Summit 2023 in Berlin Read my 2023 review 2022 Setup slides. https://dornea.nu/cv/papers/ Mon, 23 May 2022 14:34:04 +0200 https://dornea.nu/cv/papers/ Binary analysis - Brief overview University Feb 2012 - Jul 2012 This article was written during an IT security related seminar at the university.
