Since I am currently studying at the university, I possess knowledge of the following OSI layers:
- Physical (Fiber, wireless, repeaters)
- Data link (Ethernet, PPP, switch, bridge)
- Network (packets, IP, ICMP, IPSec)
- Transport (TCP/UDP, end-to-end connections)
Moreover, I have a foundational understanding of information security principles, including confidentiality, integrity, and availability.
Of paramount importance, since the beginning of 2024, I have actively engaged in CTF challenges, enriching my skills and knowledge. During this time, I have:
- Enhanced proficiency in Linux and Windows OS
- Demonstrated high stress resistance
- Gained insight into basic principles of website attacks, such as port scanning using nmap, examining the robots.txt file, and reconnaissance on subdomains and website pages using gobuster/dirbuster.
Additionally, I am a proud member of the Cyber Rangers cyber team, which as of 03/22/2024, holds the top rank in Ukraine based on overall score. I have actively participated in events such as:
- Cyber Apocalypse 2024: Hacker Royale
- BITSCTF 2024
- bi0sCTF 2024
- VishwaCTF 2024 (Received a certificate from this competition)
- GCC CTF 2024
Furthermore, I have completed Web Security courses on the PortSwigger website and successfully passed three levels of "Learn The Basics of Penetration Testing" on the HackTheBox platform.
