The Problem Sentinel Solves

Security analysts don't just collect logs—they have to make sense of them.

Sentinel Log Core takes security logs from different formats and transforms them into actionable insights through:

✅ Parsing
✅ Normalization
✅ IOC Extraction

[Rotimi Ishola @Timi_phil]

🔹 Log parsing (Text, JSON & CSV)
🔹 Detection rules
🔹 IOC extraction
🔹 Threat intelligence matching
🔹 Event correlation
🔹 Timeline generation
🔹 Parser fuzzing with libFuzzer

[Rotimi Ishola @Timi_phil]

🚀 I built Sentinel Log Core, an open-source C++ security log analysis toolkit.

It demonstrates core SOC concepts including:

Completed a hands-on Azure project deploying a scalable and secure Grafana environment using:

✅ Azure VMSS
✅ Application Gateway
✅ PostgreSQL
✅ NAT Gateway
✅ Azure Bastion
✅ Azure Monitor
✅ Entra ID
✅ Storage & DNS
Great experience working on cloud infrastructure,

[Rotimi Ishola @Timi_phil]

Covered: • Web enumeration • Application mapping • Recon techniques • Information disclosure observations

One lesson: ��Good enumeration creates good opportunities.”

[Rotimi Ishola @Timi_phil]

Just completed the TryHackMe room “Walking An Application” and published a walkthrough🕸️

A good reminder that understanding how a web application works is often the foundation of finding vulnerabilities.

Excited to share that I’ve completed my Cyber Security Analyst (L1 SOC) internship with Duskbeacon.

During this experience, I worked on:👇

#CyberSecurity #SOC #BlueTeam #SIEM

[Rotimi Ishola @Timi_phil]

• Security monitoring and alert triage in a SOC environment.
• Threat intelligence using tools like VirusTotal and AbuseIPDB • Incident validation, escalation, and reporting
This journey strengthened my skills in SIEM, incident response, and real-world threat analysis.👇
