RAMESH KRISHNA SARATHIPERSONAL PORTFOLIO / 2026
DETECT · DEFEND · DETER
I'm an Information Security postgraduate focused on understanding how attacks happen, how risk is managed, and how security teams respond.
At Royal Holloway, I studied cryptography, network security and security management, performed academic risk assessments, and analyzed cloud-based DDoS attack patterns.
Beyond cybersecurity, I bring experience in business development, Android development and web development. Today I am building SHIELD as an emerging cybersecurity and AI initiative while pursuing junior cybersecurity and SOC analyst roles.

Example security risk register
This example demonstrates how a risk can be captured, assigned an owner and addressed through proposed security controls. Residual scores require real evidence before acceptance.
| Risk scenario | Initial | Proposed controls | Owner | Illustrative residual |
|---|---|---|---|---|
| Unauthorised SaaS access | High | MFA, least privilege, access reviews | IT / IAM | Medium |
| Untested backup recovery | High | Recovery testing, documented recovery targets | IT Operations | Low* |
| Inconsistent awareness | Medium | Role-based training and completion tracking | Security / HR | Low* |
*Residual values are hypothetical. This is an educational illustration, not a completed risk assessment or audit, and does not imply professional certification.
