About Ismail Melih Tas

I believe in continuous improvement. I try to make small continual improvements every day which will be compounded over time and give me desirable results. Improving every day, in every way, I will be better. I believe investing a significant amount of time daily to develop a growth mindset, have new knowledge, learn new skills will change my perception and allow me to anywise combine them in creative ways to contribute to my life.I believe making excuses limits and prevents people from growing personally and professionally. I am responsible for what happens next in my life. So it is not about what I have or what I am dealt with, but how I take role/action and play the game.Selected Presentations:2020 - BlackHat Arsenal EU 2020, “Mr.SIP: SIP-Based Audit and Attack Tool”2020 - DEF CON 28 Main Stage, "Practical VoIP/UC Hacking Using Mr.SIP"2019 - University of Oxford, “Practical Bug Hunting Methodology”2019 - BlackHat Arsenal EU 2019, “Mr.SIP: SIP-Based Audit and Attack Tool”2019 - BlackHat Arsenal USA 2019, “Mr.SIP: SIP-Based Audit and Attack Tool”2019 - Offzone Moscow 2019, “SIP-Based Attacks & Defense Approaches” 2019 - BlackHat Arsenal Asia 2019, “Mr.SIP: SIP-Based Audit and Attack Tool”2018 - Bogazici Uni., “Practical Bug Hunting Techniques”2017 - Bilgi Uni., “Tactical Bug Hunting Methodologies”2016 - ICR Workshop, “Our Proposed SIP-Based DRDoS Attacks & Effective Defense Mechanism”, Tallinn2015 - SAU Cyber 2015, “Being Security Researcher and VoIP Security”2012 - NopCon 2012, "Unified Communications Security Risks and Defense Strategies”2012 - NopCon Uni. 2012, "VoIP Security & SIP Attack Techniques"2011 - Cyber Security Conf. 2011, METU, "VoIP Hacking & SIP Security"Academic Journal Articles as First Author (SCI-Indexed):2020 - IEEE Access, "A Novel SIP Based DRDoS Attack and an Effective Defense Mechanism"2016 - Elsevier, Computers & Security, “Novel SIP-Based DDoS Attacks with Effective Defense Strategies”, More academic publications: https://scholar.google.com.tr/citations?user=Ss6rwWkAAAAJ&hl=trGovernment-Level Policy: 2015 - Author of National VoIP/UC Security Strategy Standard (coop w/TSE)Competitions:2020 - Champion of National Cyber Security Thesis Comp.
