About

** WebShield IDS — Extension Description

WebShield IDS is a browser-based intrusion detection and URL security extension designed to protect users from phishing, malware, and malicious websites in real time.

It operates using a hybrid detection approach that combines machine learning models with deterministic security heuristics to analyze URLs during normal browsing activity.

* Key Capabilities

Real-time detection of malicious and suspicious URLs

Classification of URLs into phishing, malware, defacement, or benign categories

Ensemble-based decision logic for improved accuracy and reduced false positives

Detection of typosquatting, brand impersonation, and deceptive domain patterns

Confidence-driven risk scoring to prioritize high-risk threats

Lightweight architecture with minimal impact on browser performance

* How the Extension Works

Monitors URL changes during active browsing sessions

Extracts structured features from the URL (domain structure, entropy, keywords, similarity patterns)

Applies heuristic checks and local threat intelligence first

Uses machine learning models only when necessary

Produces a final decision based on combined signals rather than a single source

All analysis is performed automatically and only when relevant.

* Privacy and Data Handling

No personal user data is collected, sold, or shared

URL analysis is performed solely for security evaluation

No browsing history is stored beyond the active session and scan history relevent according to user requirements and can be cleared by user on click on a button.

No tracking, profiling, or advertising functionality is included

* Intended Audience

Users seeking protection from phishing and malicious links

Students and professionals browsing unfamiliar or untrusted URLs

Individuals who want an additional, automated layer of browser security
