Where I Add Security Value

A practical, layered approach to defense — from perimeter monitoring to post-incident forensics — tailored to enterprise, NGO, and government environments operating in Central Equatoria and beyond.

Network Security & Monitoring

Enterprise firewall configuration, real-time traffic inspection, packet analysis, and intrusion detection to keep unauthorized activity out and visibility in.

// NETSEC

Vulnerability Assessment & Auditing

Systematic identification of security flaws, misconfigurations, and exposure points across systems and infrastructure — before an attacker finds them.

// VULN-ASSESS

Digital Forensics & Incident Response

Analysis of system artifacts and logs to reconstruct attack vectors, contain active threats, and support post-incident recovery and reporting.

// DFIR

Hardware & Infrastructure Hardening

Device security audits, firmware analysis, and secure configuration protocols to reduce attack surface across physical and virtual infrastructure.

// HW-HARDENING

Security Operations & Compliance

Implementing industry-standard best practices for day-to-day security operations, tailored for both local and remote-managed environments.

// SECOPS

Threat Monitoring & Telemetry

Continuous log analysis and alert triage using custom telemetry pipelines, built to surface real threats and suppress noise.

// MONITORING

Selected Work

A sample of engagements demonstrating methodology, tooling, and measurable security outcomes.

CASE STUDY / NETSEC-HARDENING

Network Infrastructure Security Audit & Hardening

A full-scope audit of a multi-site organizational network, closing exposure gaps across firewalls, switching infrastructure, and remote access points.

SCOPE
Perimeter firewall review, internal segmentation analysis, VPN and remote-access configuration audit across a distributed office network.
TOOLS USED
Nmap · Wireshark · Nessus-class scanners · vendor firewall CLI
OUTCOME
Identified and remediated critical open-port exposures and flat-network risks, implemented segmentation policy, and delivered a hardened baseline configuration with ongoing monitoring recommendations.
CASE STUDY / WIRELESS-RF

Wireless Protocol & Handshake Vulnerability Analysis

An authorized assessment of enterprise wireless deployments, evaluating handshake integrity and encryption posture against modern attack techniques.

METHODOLOGY
Controlled capture and analysis of WPA2/WPA3 handshake exchanges, rogue access point detection, and signal-boundary mapping to assess real-world exposure.
TOOLS USED
Wireshark · Aircrack-ng suite · Kali Linux
RISK MITIGATION
Recommended migration to WPA3-Enterprise, certificate-based authentication, and segmented guest networking — reducing credential-capture risk substantially.
CASE STUDY / TELEMETRY-BUILD

Custom Security Telemetry & Log Monitoring System

Design and deployment of a lightweight, centralized log monitoring pipeline for real-time visibility into infrastructure activity.

ARCHITECTURE
Centralized log aggregation from endpoints and network devices into a single analysis layer, with rule-based alerting for anomalous behavior.
TOOLS USED
Security Onion · Ubuntu Server · custom detection rules
DEPLOYMENT
Delivered a running real-time detection environment with dashboards and alert triage workflows, reducing mean time to detection for the client team.

About TommieSec

I'm a cybersecurity specialist working out of Juba, South Sudan, focused on giving organizations a clear, honest picture of their security posture — and the practical steps to strengthen it. My work spans network security, vulnerability assessment, digital forensics, and infrastructure hardening, applied to environments ranging from local businesses to NGOs and government agencies.

Operating from Central Equatoria, I understand the specific infrastructure and connectivity constraints facing organizations in this region, while holding every engagement to international security standards. I approach each assessment methodically: understand the environment, map the attack surface, verify findings, and deliver remediation guidance that teams can actually act on.

Security is not static, and neither is my practice. I maintain a continuous learning discipline across both offensive and defensive operations — tracking emerging threats, refining detection techniques, and testing new tooling — so that the guidance I give clients reflects the current threat landscape, not last year's.
