Three system calls were implemented to achieve the synchronization. A patchfile was used to patch and build the new kernel with system
calls. Linux Kernel , multi-thread programming , building linux , linux patching
4. Distributed Journal file system in C in Multi-threaded architecture: File System in an error-prone environment was implemented by
using various distributed systems consistency/atomicity/Recovery models. Error recovery mechanisms for partial writes were implemented to
provide a higher layer atomicity and consistency. Various approaches for atomicity were explored. Skills : C programming , Atomicity-
Consistency approaches , File Systems
5. Don't care positions in a Covering Array using parallel programming in OpenMP: In this project ,parallel programming using openMP
was used to find the 'don't care' positions in a covering array. A comparative study was done for : use of openMP vs serial program for
various datasets. ASU high performance computing cluster with 16 cores was used to do the parallel programming. Skills: C , parallel
programming , open MP, Intel Advisor XE

Strace,GDB.Path attacks , TOCTTOU attacks , Overflow attacks, ShellCode. Used X86 assembly , process internals ,stack , system security ,system
calls , Linux , C programming , X86 Assembly
2. Data exfiltration by byte level modification of IP Datagrams (Stealth Network attack) by bypassing security features. Network
Stack programing. Exploiting vulnerabilities in Linux environment and network protocols. TCP/IP, UDP,
3. Implemented the Morris worm Host Discovery Functionality using python. Created a parser to extract host names known and trusted
by the current host by scanning through appropriate files in the Linux environment of the host. Python, Linux
5. P2P file sharing system using network programming in Java. Protocols used UDP, TCP, HTTP, Multi-threaded Clients and Servers,
Sequencing, Time-outs were implemented at application layer to provide reliable communication. A bit-torrent/Napster type system was
implemented. A central server and peer interaction was implemented using UDP to provide a HTTP 1.0 type of functionality. Java, J2EE, socket
