I am a Cyber Security professional with 6 months of hands-on internship experience at Cyberhunt IT Solution. I successfully built an enterprise SOC lab using Splunk ES and developed detection rules that identified and mitigated 15 different attack vectors, including brute-force attempts and suspicious PowerShell activity. I'm building toward a Cybersecurity Engineer role, where I can leverage my strong technical and analytical skills to enhance security measures and protect critical systems.
