//! FJ-1390: Static IaC security scanner — 10 detection rules.
//!
//! Popperian rejection criteria for:
//! - SS-1: hardcoded secrets (password, token, api_key, secret, AWS_SECRET)
//! - SS-2: HTTP without TLS (http:// except localhost)
//! - SS-3: world-accessible permissions (mode last digit >= 4)
//! - SS-4: missing integrity check (external source, no check block)
//! - SS-5: privileged container (env privileged=true, root owner)
//! - SS-6: no resource limits (Docker without MEMORY/CPU limits)
//! - SS-7: weak crypto (md5, sha1, des, rc4, sslv3, tlsv1.0)
//! - SS-8: insecure protocol (telnet://, ftp://, rsh://)
//! - SS-9: unrestricted network (0.0.0.0, bind_address: *)
//! - SS-10: sensitive data (ssn=, credit_card=)
//!
//! Usage: cargo test --test falsification_security_scan
