Graduate Assistant – Wichita State University September’2014 - May’ 2016


oWorked as a Graduate Assistant and used to support customers on various issues related to Layer2/Layer3 technologies such as Spanning-tree, VLAN, OSPF, DHCP and IP addressing.

oUsed protocols based on a methodology called differentiated key pre-distribution.

oSpanning tree protocol is used to obtain the shortest possible route; in that way we can send the packets in quick time.

oWorked on Windows OS 7,8,10 and troubleshooted all the various issues related to it.

oStatic route configuration and virtual LAN technologies were used to enhance the secure transmission of data.

oDocument, implement test plans and test cases deriving information from existing deployments, consulting with developers and evaluates existing test case accuracy and coverage.

oCommunicate test results to other engineers and cross-functional teams.


+ Novel Security Scheme for online banking based on Virtual Machine:

oDeveloped the project “Novel Security Scheme for online banking based on Virtual Machine” and implemented the database on Oracle 10g. The current online banking scheme built on ordinary software stack, which comprises of the operating system and its applications running on it, is facing attacks including Phishing, Pharming, Malicious Software Attacks (MSW), Man in the Middle Attacks (MITM) and Key logger. Here, we used C language, .net and introduced the Domain Online Banking, a novel security scheme for online banking that combines the virtual machine (VM) technology with web services.

+ Women security system using RFID:

oDesigned a project “Women security system using RFID” to build a security system for women which allows immediate response in case of any harassment. Here, we used JAVA language and the concepts of wireless sensor networks in implementing a RFID tag in an electronic device.
