As a Cyber Security engineer with a focus on network security, I have 2 years of experience in managing and securing computer network systems. I have expertise in DNS, DHCP, Routing protocols, Linux configuration, and the OSI model. Additionally, I am skilled in using network simulation tools like GNS3 and Packet Tracer to test and validate network designs before deployment. I also have a good understanding of network segmentation, access control, and authentication mechanisms. Pursuing professional development opportunities is important to me, and I have earned relevant certifications such as CompTIA Network+ and Cisco Certified Network Associate (CCNA). I am always looking for ways to improve my knowledge and stay current with the latest trends and technologies in network security.
