Hi! The part about not making any critical changes without approval and providing a full audit trail is smart — many “security experts” skip these, which can cause bigger problems later. I’ve done hands-on hardening and audit on Ubuntu, Debian, and Windows Server for SaaS apps handling sensitive user data — including server-side firewall review, access logs, and SSH review. Last month, I secured a Linux server stack used for a live AI platform, where transparency and a leave-no-trace policy were required. For your case, I’d start by reviewing login and network logs, scan for rootkits or unauthorized users, then step through firewall rules, SSH, and database access. Every step can be logged and paused for approval if something looks critical. One question — do you already have central log collection enabled, or will I need to set that up as part of the review? Happy to send a free 1-page checklist of what I’d cover, up front, so you can see the flow. You’ll find some relevant IT security work in my portfolio at work.techindika.com. — Pradeep

I can investigate your server, identify any active compromise or misconfiguration, and harden everything to a defensible baseline. My approach: review SSH config, authorized keys, login history, and active sessions for unauthorized access; audit firewall rules, open ports, and exposed services against what should actually be running; check API endpoints, database permissions, and file ownership for over-privilege; review logs for indicators of compromise; and deliver a written report with every finding, severity, and specific remediation steps. I work on Linux environments and have GCP experience. Hardening engagements like this typically run one to two days depending on the surface area. If you can share your OS version and hosting environment, I can scope the work and confirm timeline. Vicente

Application security enthusiast focused on real-world web security research across production-grade systems. I work on understanding how modern applications enforce security across layered architectures involving CDNs, WAFs, reverse proxies, and backend APIs. My focus areas include: - Web application security in real production environments - API security and broken access control analysis - Authentication and session trust boundary weaknesses - Multi-tenant isolation and authorization flaws - Business logic vulnerabilities in complex workflows - Edge vs backend consistency and request handling behavior I actively study how security controls behave under adversarial conditions and how trust is established and validated across distributed systems. My approach is highly analytical and impact-driven — I focus on mapping system architecture, identifying weak trust assumptions, and understanding how real-world security failures emerge in large-scale applications. Currently focused on advancing deep-dive vulnerability research, secure system design thinking, and responsible disclosure in real-world environments.
