Ángel Longueira-Romero

Bio

I am a PhD student from Mondragon University in Spain, currently working in the Industrial Cybersecurity Team at IKERLAN in The Basque Country, Spain.

I hold a Master's degree in Automation Engineering and Industrial Informatics, and a Bachelor's degree in Industrial Electronics and Automation Engineering, both from the University of Oviedo.

Research Interests

My research focuses on system security, and more precisely, I am interested in security testing methodologies for Embedded Systems (ES). I would like to measure quantitavely the partial level of security of each asset or component of the ES, and then, compute the overall security value associated to the hole device. The most powerfull means to achieved these goals are security metrics, specially those proposed in the standards, such as the CPE, CWE, CVE, CVSS, or CAPEC.

The most interesting point in my research will be the use of standardised security metrics. Available methodologies do not usually propose metrics to know the level of security reached with all the controls and countermeasures. And when metrics are proposed, they are usually qualitative, or the way to obtain a final value is not clearly explained, nor can be applied to embedded systems. You can take a look to the more than 500 security metrics that were reviewed.

To overcome this, I am analysing the ISA/IEC-62443 standard to propose possible enhancements, and to integrate metrics in its evaluation process. The ISA/IEC-62443 is a series of standards, technical reports, and related information that define procedures and requirements for implementing electronically secure Industrial Automation and Control Systems (IACS).

Because of my background, I usually work on my own projects about electronics. I am passionate about designing and building circuits, PCBs, vacuum tubes and solid state amplifiers and anything of this kind.
