Quantum Threat Context
Why post-quantum cryptography matters and how this server is protected.
2022 – 2024
NIST PQC Standardization
NIST finalizes FIPS 203 (ML-KEM / Kyber), FIPS 204 (ML-DSA / Dilithium), FIPS 205 (SLH-DSA / SPHINCS+). First post-quantum standards ready for deployment.
2025 – 2026 (now)
Early Hybrid Deployment — This Server
OpenSSL 3.5 ships ML-KEM natively. Chrome 124+, Firefox 132+, and this Apache instance negotiate X25519MLKEM768 / SecP384r1MLKEM1024 hybrid key exchange. Classical + PQC keys are combined — breaking either requires breaking both.
~2030
Harvest Now, Decrypt Later risk materializes
Adversaries may already be archiving encrypted TLS traffic today. If a sufficiently powerful quantum computer becomes available by 2030, any RSA/ECC-only session recorded today could be decrypted retroactively. PQC hybrid KE prevents this.
2030 – 2035 (estimated)
Cryptographically Relevant Quantum Computer (CRQC)
Conservative NIST and NCSC estimates suggest a CRQC capable of breaking RSA-2048 and P-256 ECC within this window. Exact timeline is contested; defensive posture requires acting now.
ML-KEM security basis
Module Learning With Errors (MLWE)
ML-KEM is based on the hardness of MLWE, a lattice problem with no known efficient quantum algorithm. NIST Level 3 (ML-KEM-768) provides ~192-bit post-quantum security. The hybrid approach adds a classical key — even if PQC is somehow broken classically, the classical component still protects.
OWASP Coverage — This Endpoint
OWASP Top 10 (2021)
| ID | Category | Status | Mitigation in place |
|---|---|---|---|
| A01 | Broken Access Control | Mitigated | No writable endpoints; all routes return read-only diagnostic data; default-deny vhost blocks unknown hosts |
| A02 | Cryptographic Failures | Mitigated | TLS 1.3 + PQC hybrid KE; HSTS enforced; ECDSA P-384 cert; AES-256-GCM preferred; no plaintext fallback |
| A03 | Injection | Mitigated | No database, no shell execution of user input; all output escaped via html.escape(); WSGI isolates HTTP from OS |
| A04 | Insecure Design | Mitigated | Security by design: least privilege, defence-in-depth, fail-secure defaults; no sensitive data stored; read-only WSGI app |
| A05 | Security Misconfiguration | Mitigated | Hardened Apache: server tokens off, directory listing off, mod_evasive, custom error pages, security headers enforced |
| A06 | Vulnerable & Outdated Components | Mitigated | Ubuntu 26.04 LTS; OpenSSL 3.5 (ML-KEM native); Apache 2.4 current; no third-party libraries in WSGI app |
| A07 | Identification & Auth Failures | N/A | No authentication mechanism; endpoint is intentionally public read-only within authorized lab scope |
| A08 | Software & Data Integrity | Mitigated | No external package dependencies; no dynamic code execution; WSGI app is self-contained and version-controlled |
| A09 | Security Logging & Monitoring | Mitigated | Apache access/error logs with client port; fail2ban jails; session history recorded; syslog forwarding available |
| A10 | Server-Side Request Forgery | Mitigated | No user-controlled URL parameters; internal probes (TLS probe, headers probe) use hardcoded 127.0.0.1 only |
OWASP API Top 10 (2023)
| ID | Category | Status | Mitigation in place |
|---|---|---|---|
| API1 | Broken Object Level Authorization | N/A | No object-level resources or identifiers exposed |
| API2 | Broken Authentication | N/A | No authentication — public read-only endpoint by design |
| API3 | Broken Object Property Level Auth | N/A | No user-settable properties; all fields server-computed |
| API4 | Unrestricted Resource Consumption | Mitigated | mod_evasive rate limiting; RequestReadTimeout; sysctl SYN cookies; fail2ban; UFW rate limit rules |
| API5 | Broken Function Level Authorization | N/A | Single function: serve diagnostic page. No privileged functions exposed |
| API6 | Unrestricted Sensitive Business Flows | N/A | No business flows; lab endpoint only |
| API7 | Server-Side Request Forgery | Mitigated | Internal probes use static hardcoded addresses; no user input reaches network calls |
| API8 | Security Misconfiguration | Mitigated | Same as A05: hardened Apache, no defaults, minimal attack surface |
| API9 | Improper Inventory Management | Mitigated | Single versioned endpoint per domain; no shadow or undocumented routes |
| API10 | Unsafe Consumption of APIs | Mitigated | No external API calls; internal probes (NTP, DNS, OpenSSL) are read-only diagnostic queries |
Security by Design — Implemented Principles
| Principle | How it is applied here |
|---|---|
| Minimise attack surface | Read-only WSGI app; no file upload, no forms, no database, no shell exec; default-deny vhost drops unknown Host headers |
| Secure defaults | TLS enforced on first connection; HSTS with 2-year max-age; session tickets disabled; PQC groups active without opt-in |
| Least privilege | WSGI daemon runs as www-data; private key mode 0600 root:root; app directory 0755; no root-owned writable paths in WSGI |
| Defence in depth | TLS (transport) + security headers (browser) + mod_evasive (rate) + fail2ban (IP ban) + UFW (network) — multiple independent layers |
| Fail securely | Errors return generic messages; server tokens hidden; directory listing disabled; WSGI exceptions caught and logged, not exposed to client |
| Avoid security by obscurity | Security depends on strong crypto (ML-KEM, AES-256, ECDSA P-384) and correct configuration — not on hiding server identity |
| Separation of duties | Certificate management (local Python script) separated from server hardening (server bash script) separated from application logic (WSGI app) |
| Fix security issues correctly | Configuration generated from validated templates with backup/rollback; each hardening step idempotent and logged |
