Profile
Jeff Lomas grew up building and learning about computers. Five years ago, he became a digital forensic examiner in law enforcement and now he investigates cyber-related crimes.
The world of cybersecurity is a challenging field where few know everything. Jeff loves the digital forensic, cyber investigative, and OSINT community because we all learn from each other and he’s finds it to be very inclusive, even for new people.
His work requires him to maintain technical skills as well as perform non-technical administrative duties. Jeff appreciates that, knowing that many of his students are in similar positions, and he often leverages their shared experiences to show students how to be successful while wearing many hats.
Two of Jeff’s passions are learning and teaching. Becoming a SANS Instructor gave him the ability to fulfill both, as he’s been able to learn from students and colleagues, and each of their unique experiences.
Jeff Lomas works as a Detective and Digital Forensic Examiner at the Las Vegas Metropolitan Police Department and has proudly served the Las Vegas community since 2008. His view of OSINT is unique as he started using OSINT while performing digital forensics for his primary job. Having knowledge from the digital forensic side and investigative side has enabled him to become a well-rounded digital forensic examiner and cyber investigator.
OSINT changes by the minute and the techniques that Jeff often describes as a SANS instructor in SANS SEC497: Practical Open-Source Intelligence (OSINT), may be different than what are explained in the base material received in class. Jeff’s goal is to give students the ability to recognize these challenges and learn how to use OSINT in multiple different ways to find the answers they're looking for.
Jeff’s academic credentials include a bachelor’s degree in Intelligence Management with a focus in Cybersecurity and a master’s degree in Cybersecurity. He is a faculty member of the SANS Technology Institute, an NSA Center of Academic Excellence in Cyber Defense and multiple winner of the National Cyber League competition. Jeff currently holds (and or held) various industry certifications such as GSEC, GOSI, ACE, CFCE, CCME and CAIE.
Jeff is a blog contributor for Osintcurio.us, a judge for Trace Labs, a member of NCPTF (National Child Protection Task Force), and a volunteer for ATII (Anti-Human Trafficking Initiative).
When he’s not working or teaching, Jeff enjoys spending time with his family and playing multiple instruments such as guitar and ukulele, and he also enjoys playing various board games.
Why is it important to continuously learn and train yourself?
