Work History
CCNA Trainer
Unpaid Voluntary Work
09.2022 - Current
- Delivered dynamic presentations on key CCNA topics, facilitating active engagement from all participants in the learning process.
- Stayed current with advancements in networking technology, allowing for accurate instruction on relevant industry trends and practices.
- Improved CCNA training outcomes by incorporating real-world scenarios and hands-on activities in lesson plans using Cisco Packet Tracer and EVE-NG.
Wormhole Attack Prevention on BGPsec
University Projects
09.2023 - 12.2023
- Developed and tested a scenario using Cisco routers in EVE-NG to illustrate a wormhole attack, where two malicious ASes collude to create a GRE over IPsec tunnel. This tunnel is used to advertise a prefix with a shorter AS-PATH attribute, enabling them to hijack the prefix even when BGP security mechanisms like BGPsec were in place.
- Proposed mitigation technique for countering wormhole attacks on BGPsec and enhancing its security by appending AS-PATH multiple times before advertising the path from ISP to organizations.
Python Program to Deploy Firewall in SDN
University Projects
05.2023 - 08.2023
- Develop a Python program to interface with SDN controller via REST API.
- Implement NetConf rules deployment by the controller based on network topology and policies to enforce firewall functionalities.
- Manage packet handling decisions such as dropping, modifying, or allowing passage in accordance with controller directives using Deep packet Inspection procedures performed by firewalls .
- Utilize Wireshark for the establishment of a robust monitoring environment.
TLS Implementation on Top of UDP
University Projects
01.2023 - 04.2023
- Implementing reliable data Transfer Protocol on top of UDP using Go-Back_N concepts between sender and receiver in Python.
- Implementing TLS handshake protocol where the key exchange algorithm between sender and receiver can be ECDHE or RSA, digital signature and certificate can be DSS or RSA, the encryption/decryption algorithm after deriving session keys is AES-128 in CBC mode, and SHA256 as Hash function.
- TLS Record Protocol to bring encryption, authentication, and integrity using session keys derived in the handshake process.
A Comparative Study on OSPF and EIGRP
University Projects
09.2022 - 12.2022
- Conducted a comprehensive analysis of routing protocols in Terms of their Routing Algorithm, Routing cost, Best Path selection, convergence time, Queuing delay.
- Optimal Routing analysis in EIGRP using EVE-NG where input traffic can be shared on Cisco routers in the case that the link cost of the outgoing paths is unequal.
