You have a secure building with many rooms (your network). Each room represents a device or a user. Most of the time, what’s happening inside each room is hidden.
But what if you want to monitor what’s going on—without disturbing or exposing anything?
That’s what SPAN and RSPAN are for. They’re digital security cameras for your network.
- What it does: Makes a copy of all the digital traffic (like emails, files, apps) going in and out of a certain port (or “room”).
- Where it sends it: To a monitoring system like a cybersecurity tool (SIEM, IDS, etc.).
🧠 Think of it as placing a camera right at the door of a room to watch who goes in or out—without blocking them.
- What it does: Same as SPAN—but it lets you watch traffic happening in another building (or another part of your network).
- Where it sends it: The copied traffic is sent across the network to a remote location for analysis.
🧠 It’s like sending a live camera feed to a command center in another city.
| Benefit | Explanation |
|---|---|
| Incident Response | Security teams can “see” what happened during or after a breach. |
| Compliance & Auditing | Regulators often require activity logging—SPAN helps create this trail. |
| Threat Detection | SPAN lets AI or human analysts catch suspicious patterns in real time. |
| Zero Trust Forensics | In systems like ZeroTrustBSD, SPAN helps prove policy enforcement is working. |
In the context of ZeroTrustBSD, SPAN is tightly integrated with microsegmentation and threat detection. Each “camera” is placed with precision—only watching what’s necessary, and always under cryptographic policy.
It’s not about surveillance. It’s about resilience, evidence, and control.

Quantum Key Distribution (QKD) is a method of distributing encryption keys using quantum particles—typically photons. Its security is based on the laws of quantum mechanics.
- Photons are transmitted with quantum states (e.g., polarization).
- The receiver randomly measures the photons.
- Both parties compare results and keep only matching basis values.
- Any eavesdropping attempt introduces detectable anomalies.
- Based on physics, not math
- Eavesdropping is detectable (via Quantum Bit Error Rate)
- Immune to quantum computer attacks
- Requires expensive specialized equipment
- Works best over fiber or line-of-sight paths (≤100 km)
- Not practical for large-scale global deployment
📚 References:
Post-Quantum Cryptography (PQC) consists of cryptographic algorithms that are secure against both classical and quantum computers, but do not require quantum technology.
PQC algorithms rely on mathematically hard problems like lattice reduction, multivariate equations, and hash functions.
- Kyber (encryption)
- Dilithium, FALCON, SPHINCS+ (signatures)
- Classic McEliece, NTRU (encryption)
- Standardized by NIST in 2022.
- Runs on classical hardware
- Internet-scalable and backward compatible
- Already in pilot deployment stages
- Larger key sizes and signature overhead
- Still under active evaluation
- May be slower in embedded environments
📚 References:
| Feature | QKD | PQC |
|---|---|---|
| Based on Physics | ✅ Yes | ❌ No (math-based) |
| Needs Special Hardware | ✅ Yes (QKD devices) | ❌ No |
| Internet-Scalable | ❌ No | ✅ Yes |
| Immune to Quantum | ✅ Yes | ✅ Yes |
| Detects Eavesdropping | ✅ Yes | ❌ No |
| Used in TLS | ❌ Not yet | ✅ Kyber & Dilithium (in trials) |
Both QKD and PQC aim to secure communications against the threat of quantum computing, but approach it differently:
- QKD = Use light and quantum states to share keys securely.
- PQC = Use post-quantum algorithms to replace RSA/ECC across digital systems.
A hybrid model may offer the best defense; QKD for high-assurance key distribution, and PQC for global digital infrastructure.
