About Me
Hello — I'm Janitha, a Cyber Security Analyst. I work at the intersection of secure operations, cyber security analysis, and telco signaling awareness.
My path blends DevOps discipline with a security mindset: how systems are built, observed, and defended — including signaling-plane risk in telecom environments. I am currently following CompTIA Security+.
Domains I am oriented around:
- ▹Cyber Security Analysis
- ▹DevOps & Secure Ops
- ▹Telco Signaling Security
- ▹Linux & secure ops habits

Focus
Three domains define the current path — analysis, secure operations, and telco signaling security. No employer labels; just the work I am oriented around.
Domain
Cyber Security Analysis
Threat and risk mindset, secure practices, and a structured path through CompTIA Security+.
Domain
DevOps & Secure Ops
Linux-oriented operations, monitoring habits, and hardening as part of how systems stay reliable.
Domain
Telco Signaling Security
Signaling-plane awareness with an SS7-oriented security path—how telecom control channels can be abused and defended.
Focus · Cyber Security Analysis
Ongoing
- ▹Building a structured cyber security analyst foundation while following CompTIA Security+.
- ▹Practicing threat and risk mindset: what to protect, how systems fail, and how controls reduce exposure.
- ▹Studying secure practices across identity, networks, and operational hygiene.
