As a Senior Cybersecurity Engineer at Bistwork, I undertake several critical functions to ensure the security and protection of the organization's digital assets. My key responsibilities include:- Simulated Attacks: As part of Red Team operations, I orchestrate simulated real-world attacks on our client's infrastructure. These encompass exploiting zero-day vulnerabilities, conducting advanced network penetration testing, bypassing security controls like firewalls and intrusion detection systems, and utilizing techniques such as buffer overflows and SQL injection.- Code Vulnerability Review: I oversee the implementation of code review processes to identify and address vulnerabilities in software applications and systems. - Penetration Testing: In my role leading Red Team operations, I simulate real-world attacks on our client's infrastructure. This involves exploiting zero-day vulnerabilities, conducting advanced network penetration testing, bypassing security controls such as firewalls and intrusion detection systems, and leveraging techniques like buffer overflows and SQL injection

- Managed the response to cybersecurity threats and incidents, orchestrating plans for incidentresponse and conducting vulnerability assessments across networks, operating systems, cloudcomputing systems, and scan-based applications. Utilized automated tools such as Nessus, Microsoft Baseline Analyzer, OpenVAS, Nikto, and Burp Suite to enhance response efficiency. - Spearheaded penetration tests on web technologies, databases, and networks, employing advanced hacking techniques to escalate privileges and exploit vulnerabilities. Proficient in conducting internal and external network exploitation, application exploitation, and code review. Employed methodologies including SQL injection, cross-site scripting (XSS), session hijacking, directory traversal attacks, firewall evasion techniques, VLAN hopping, ARP spoofing, and DNS poisoning to comprehensively assess and mitigate vulnerabilities. Additionally, conducted assessments on web server misconfigurations, insecure network protocols, and weak encryption algorithms to ensure a robustnetwork security posture.- Led a team of software engineers, developers, system network administrators, and other associates, ensuring secure design, development, and implementation of applications and networks. Employee methodologies including SQL injection, cross-site scripting (XSS), session management vulnerabilities, insecure deserialization, sensitive data exposure, broken authentication, and XML external entity attacks to assess and mitigate vulnerabilities. Additionally, conducted secure code reviews to identify and address potential security flaws, focusing on common vulnerabilities such as buffer overflows, insecure cryptographic storage, and improper input validation.

- Conducted comprehensive network traffic analysis, utilizing techniques such as examining raw packet data, network flow analysis, interpreting output from Intrusion Detection Systems (IDS), and leveraging customized sensor data derived from communication networks.- Proficient in setting up, configuring, and maintaining web servers on both Windows and Linux platforms, ensuring optimal performance and security.- Designed, implemented, and maintained local networks and network segments, including the configuration of routers, switches, and other network systems to support seamless communication and data flow.- Spearheaded the design, configuration, and installation of a robust network datacenter tailored to accommodate over 1000 users, encompassing load balancers, Firewall configuration, and Intrusion Detection Systems (IDS) to fortify network security posture.
