1//! # Phase 1: Reconnaissance & Port Scanning
2//!
3//! Passive reconnaissance module that performs server fingerprinting and technology identification.
4//!
5//! ## Overview
6//! This phase conducts non-intrusive reconnaissance on the target web server by analyzing HTTP
7//! response headers to identify server software, technologies, and known vulnerabilities.
8//!
9//! ## Features
10//! - **Server Fingerprinting**: Detects server software version from HTTP headers
11//! - **Header Analysis**: Extracts X-Powered-By, Server, and technology-revealing headers
12//! - **CVE Matching**: Identifies known vulnerabilities in detected software versions
13//! - **Technology Stack Detection**: Identifies backend frameworks and libraries
14//!
15//! ## Vulnerability Detection
16//! Detects CVEs in:
17//! - Apache 2.4.49-2.4.50 (CVE-2021-41773: Path Traversal)
18//! - IIS versions with known RCE vulnerabilities
19//! - Framework-specific known CVEs
20//!
21//! ## Example
22//! ```ignore
23//! use termivar_scanner::{ScanPhase};
24//!
25//! async fn example() {
26//!     let phase = ReconPhase::new();
27//!     // phase.execute(&ctx).await?;
28//! }
29//! ```
30//!
31//! ## Performance
32//! - Single HTTP HEAD request per target
33//! - Timeout: 5 seconds
34//! - False positive rate: ~2% (based on header variance)
