Rohan Jacob

A 28-yr-old graduate (4 yrs) from India, completed M Engg in Cyber Security at École Spéciale de Mécanique et d'Electricité, Ivry Sur Seine. Worked for four years, in Networking and System Administration and handling Cybersecurity. In my last job, I was given an opportunity explore various spheres of Computer Science from Coding to operations, to Sys Admin and Cybersecurity, before settling in as part of the System Administration and Cybersecurity Team. 

I joined directly in Sem 7 for M Engg with working experience, I was given a 30 ECTS Project, where I built a Private Openstack Cloud backed by MAAS and Juju on real servers. I later worked in a research project at ISEP Engineering School on internship and with extra effort could also co-author an additional research paper. My research internship at Institut supérieur d'électronique de Paris (ISEP), Issy-les-Moulineaux was on “Cyber threat detection and mitigation strategies using CVE and MITER ATT&CK framework”.

I have worked on the Active Directory and its exploitation, networking-based attacks like IP sniffing and spoofing, ARP Cache Poisoning, TCP Attacks, Kerberoasting, Pass the Hash, ICMP Relay Attacks etc. I studied concepts related to Hardware and System security, software security, learning and implementing attacks like Specter Attacks, Buffer Overflow, Return to libc, Reverse Shell, etc. I have prior experience with Linux and Windows architecture, security tools like Bloodhound for Active Directory, cracking password hashes, smbclient, impacket tools, hashcat, etc. I know Python, C++ and C(earlier). Multiple projects done are in my CV. 

Strengths - 04 yr Graduation, 05 yrs  multifarious work experience, internships, projects and certifications (CCNA for networking and RHCE for Linux Systems), fluent English, and B1 level French, Member ISACA. Travelled Asia and explored France.   Can assimilate knowledge internationally, without restrictions. Looking for Cybersecurity, Sys Administration Jobs and long term relationships with reputed firms.

Apr 2023 to Sep 2023 Research Internship, Institut supérieur d'électronique de Paris (ISEP), Issy-les-Moulineaux 

Research work on Cyber threat detection and mitigation strategies: Linking CVE to MITRE ATT&CK framework using Machine Learning Algorithms. Also co-authored an additional technical paper based on research which is expected to be presented at COMPSAC 2024 in Osaka, Japan

Sep 2022 to Nov 2022. Internship, Creation of “On Call” Penetration Testing Labs at École Spéciale de Mécanique et d'Électricité, Ivry-sur-Seine

The methodology followed for setting up Penetration Testing labs or environment as part of our training process at École Spéciale de Mécanique et d'Electricité, for Cybersecurity Major students involved manually installation of individual virtual machines. As part of my internship, I was tasked to build multiple penetration testing labs using Docker containers for use by the Academic Staff and students to use in the future as an alternative, in a faster and more efficient manner. I created the Labs effectively, thus making the process of setting up the environment efficient, faster and bypassing dependency issues that happen when manually installing Virtual Machines. Professors and students could now call the required lab with a simple command as opposed to individually finding and installing large VM files.
