Projects

Overview

Implemented comprehensive Active Directory security hardening in a lab environment, focusing on Group Policy Objects (GPOs) to enforce security baselines and reduce attack surface.

Key Features

• Configured password policies with complexity requirements and account lockout thresholds
• Implemented audit logging for security events and privilege escalation attempts
• Created baseline security documentation and change control procedures
• Reduced misconfiguration risk through standardized GPO templates

Technologies Used

Outcomes

Successfully established a hardened AD environment with documented baselines, improving auditability and reducing potential security vulnerabilities by implementing industry-standard security controls.

Overview

Developed and implemented secure baseline configurations for network infrastructure devices, focusing on eliminating legacy protocols and enforcing modern security standards.

Key Features

• Disabled insecure legacy services (Telnet, HTTP) across all network devices
• Enforced SSH v2 with strong encryption for remote management
• Configured role-based access control (RBAC) with privilege levels
• Implemented Access Control Lists (ACLs) for network segmentation
• Created comprehensive documentation for secure baseline standards

Technologies Used

Outcomes

Achieved a hardened network infrastructure with documented secure baseline, enabling faster incident triage and reducing exposure to common network-based attacks.

Overview

Explored data hiding and extraction techniques using steganography tools to understand covert communication methods and develop detection capabilities for digital forensic investigations.

Key Features

• Analyzed various steganographic techniques in image and audio files
• Used OpenPuff for multi-carrier steganography testing
• Implemented Xiao Steganography for LSB (Least Significant Bit) analysis
• Developed detection methodologies for hidden data in digital media
• Created documentation on forensic analysis procedures

Technologies Used

Outcomes

Gained practical understanding of steganographic techniques and detection methods, enhancing digital forensics capabilities for identifying covert data transmission.
