Optimizing Supply Chain Software: A Proven Framework for Building Smarter WMS, Fleet, and Inventory Systems
October 1, 2025How I Turned My Niche Hobby of Collecting 1950-1964 Proof Coins into a $50,000 Online Course on Teachable
October 1, 2025The best defense is a good offense — but only if your tools are built to last. Let’s talk about building smarter, sharper cybersecurity tools. Not flashy buzzword tools, but the kind that work *with* you, not against you. This is how we make threat detection more precise, more reliable, and more human.
Why the 1950–1964 ‘Imitation Thread’ Analogy Matters for Cybersecurity
Back in the 1950s, coin collectors obsessed over tiny details. A single hairline scratch, a faint double strike, a subtle toning pattern — those imperfections made a coin rare, valuable, *real*. That same mindset? It’s exactly what we need in cybersecurity today.
Think about it. A proof Kennedy half from 1961 isn’t valuable because it’s shiny. It’s valuable because of its anomalies — the die varieties, the cameo contrast, the way it stands out from the crowd. In the same way, modern threat detection isn’t about spotting the obvious. It’s about catching the rare, subtle, and often overlooked signals that most tools miss.
I’ve spent years in red teams and SOCs, and here’s what I’ve learned: the best analysts don’t just log data — they *collect* it. They look for patterns, like a numismatist spotting a doubled die in a stack of common coins. A zero-day exploit shows up the same way: not with a bang, but with a whisper in the logs.
Secure Coding: The ‘Grading’ Standard for Cybersecurity Tools
Just like a PR68 Cameo coin has to meet strict standards, your code should too. But too many tools are built like counterfeit coins — shiny on the outside, hollow inside. Raw SQL queries, unvalidated inputs, secrets baked into the config — it’s a time bomb.
Let’s build better. Here’s a simple, secure logging function in Python that treats every input like a suspect coin: inspect it, clean it, then log it properly.
import structlog
import re
logger = structlog.get_logger()
def log_threat_event(event_type, source_ip, payload):
# Always validate the basics
if not re.match(r"^(\d{1,3}\.){3}\d{1,3}$", source_ip):
logger.error("invalid_ip_format", ip=source_ip)
return False
if len(payload) > 8192:
logger.warning("payload_truncated", original_length=len(payload))
payload = payload[:8192]
# Strip newlines — no log injection here
payload = payload.replace("\n", "\\n").replace("\r", "\\r")
# Structured, machine-friendly logs
logger.info(
"threat_event",
event_type=event_type,
source_ip=source_ip,
payload=payload,
timestamp=structlog.processors.TimeStamper(fmt="iso").__call__(None, None, {})
)
return TrueRemember: Never trust input. Always sanitize. Use structured logging so your SIEM can actually *use* the data — not just store it.
Threat Detection: Building a ‘Proof Set’ of Detection Rules
In coin collecting, a full 1950–1964 proof set isn’t rare because it’s expensive. It’s rare because it’s complete — every piece fits, every coin verified. Your detection rules should be the same: a coherent, well-maintained collection, not a pile of random regexes.
Rule Design: From Heuristics to YARA/Sigma
Forget brittle regex patterns. Use Sigma rules — they’re portable, readable, and work across Splunk, Elastic, and Azure Sentinel. Think of them like a coin’s certification: clear, consistent, and trusted.
Here’s a Sigma rule to catch brute-force SSH attacks — the cybersecurity version of spotting a 1961 Doubled Die Reverse:

Pro tip: Version your rules like rare coins. sigma-ssh-bruteforce-v2.yaml tells the story of your detection strategy. And test it — just like a coin gets certified, your rules need validation.
Automated Rule Validation: The ‘CAC’ for Detection
Just like CAC verifies high-grade coins, automated testing verifies your rules. Run them in a safe, canary environment first — simulate attacks, check for false positives, and make sure nothing slips through.
Here’s how to do it in your CI/CD pipeline (GitHub Actions example):
- name: Validate Sigma Rules
run: |
sigtool --validate sigma-*.yaml
sigma-cli --rules sigma-*.yaml --backend elastic --query | grep -q "error" && exit 1 || exit 0
- name: Test Against Canary Logs
run: |
python3 test_sigma_rules.py --rule sigma-ssh-bruteforce.yaml --input ./canary/auth.logBottom line: A rule you don’t test is a risk you don’t need.
Penetration Testing: Ethical Hacking as ‘Die Variety Hunting’
Finding a rare die variety isn’t luck — it’s method. And the best penetration tests aren’t about running scanners. They’re about hunting for the weird, the broken, the overlooked.
Automated Recon with Custom Module Chaining
Build tools that work like a curated coin album: modular, reusable, and sharp. Here’s a Python script that checks for weak SSH banners and exposed admin panels — like scanning a proof set for hidden flaws.
import paramiko
import requests
import socket
from urllib.parse import urljoin
def probe_target(target, port=22):
# Grab SSH banner — no fancy tools, just raw connection
try:
sock = socket.socket()
sock.settimeout(5)
sock.connect((target, port))
banner = sock.recv(1024).decode().strip()
if "OpenSSH_7.2" in banner and "Ubuntu" in banner:
logger.warning("vulnerable_ssh_banner", target=target, banner=banner)
sock.close()
except Exception as e:
logger.debug("ssh_probe_failed", target=target, error=str(e))
# Check for admin paths — fast, light, effective
base_url = f"http://{target}"
admin_paths = ["/admin", "/admin.php", "/wp-admin", "/console"]
for path in admin_paths:
url = urljoin(base_url, path)
try:
r = requests.get(url, timeout=3, headers={"User-Agent": "SecurityAudit/1.0"})
if r.status_code == 200:
logger.critical("exposed_admin_panel", url=url, status=r.status_code)
except:
continueKey idea: Package each module in a Docker container. Version it. Run it in isolation. Each one is a proof coin — valuable alone, unstoppable in a set.
Integrating with SIEM: The ‘Proof Set’ of Telemetry
Your SIEM isn’t a trash bin. It’s your grading slab. Every log needs context — like a coin’s provenance, certification, and toning history.
Use OpenTelemetry to make your data clean, consistent, and useful:
from opentelemetry import trace
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.resources import Resource
resource = Resource(attributes={"service.name": "threat-hunter-v2"})
trace.set_tracer_provider(TracerProvider(resource=resource))
tracer = trace.get_tracer(__name__)
with tracer.start_as_current_span("analyze_network_flow"):
span = trace.get_current_span()
span.set_attributes({
"src_ip": "192.168.1.100",
"dst_port": 443,
"protocol": "HTTPS",
"tls.version": "TLSv1.2"
})
# Run detection logic hereNow your SIEM can correlate, analyze, and *act* — not just store.
Secure Coding: Preventing ‘Counterfeit’ Tools
A fake-toned 1950s proof coin is junk. A tool with vulnerable dependencies or hardcoded secrets is just as dangerous. Don’t build liabilities.
Use SBOMs (Software Bill of Materials) and SCA tools to audit every part of your stack. Think of it like verifying a coin’s minting history.
Here’s how to plug it into your build:
- name: Generate SBOM
run: syft . -o json > sbom.json
- name: Scan for Vulnerabilities
run: grype sbom.json --only-fixed -o tableAnd stop secrets before they ever get committed:

Whether you’re studying a 1964 Accented Hair Kennedy or hunting a brute-force attack, it’s the same mindset: see the details, trust the process, verify everything.
- Secure coding is your mint mark. No shortcuts.
- Threat detection rules are your die varieties — rare, precise, and worth testing.
- Penetration testing is the hunt for the ungraded gem.
- SIEM integration is where truth gets verified.
Build your tools like a collector builds a set: one careful step at a time. Not for show — but for lasting value. In cybersecurity, the real win isn’t just catching an attack. It’s building tools so sharp, so refined, they see it first.
Now go build something that earns a PR68 CAM — not from a grading service, but from your security team’s trust.
