Your Car Breaks Down on the Highway 🚗
Scenario: You’re driving to work and your car suddenly dies on the highway. After getting it towed, the mechanic says “Your engine overheated because the radiator was empty.”
Now you have two choices:
❌ Quick Fix: Just fill the radiator and drive away
- Result: Car works for now, but the underlying problem isn’t solved
- What happens: Next week, radiator is empty again and engine overheats
✅ Corrective Action: Find out WHY the radiator was empty and fix the real problem
- Investigation: Discover there’s a small leak in the radiator hose
- Real Fix: Replace the leaky hose AND fill the radiator
- Result: Problem is actually solved and won’t happen again
This is EXACTLY how corrective actions work in cybersecurity! Instead of just patching problems, you find the root cause and fix it properly.
What Are Corrective Actions? 🔧
Simple definition: Corrective actions are steps taken to fix problems AND prevent them from happening again.
Even simpler: It’s learning from mistakes and making sure you don’t repeat them.
The 5 Whys: Detective Work Made Simple 🕵️
The best tool for finding root causes is asking “Why?” five times in a row.
Example: Company Gets Hacked
Problem: Hacker accessed customer credit cards
Why #1: Why did the hacker get the credit cards? Answer: They logged into the payment system
Why #2: Why could they log in? Answer: They had an employee’s username and password
Why #3: Why did they have the employee’s password? Answer: Employee used “password123”
Why #4: Why was the password so weak? Answer: No company policy requiring strong passwords
Why #5: Why was there no password policy? Answer: Small business owner didn’t know this was important
Root Cause: Lack of basic security awareness and policies!
Corrective Actions:
- Immediate: Change all passwords, remove hacker access
- Root Cause: Create password policy, security training, password manager
Real Examples You Already Use 🏠
You do corrective actions naturally:
Burned Dinner:
- Quick fix: Order pizza
- Root cause: Got distracted by phone
- Corrective action: Set timer, silence phone while cooking
Locked Out of House:
- Quick fix: Call locksmith
- Root cause: Only had one key
- Corrective action: Hide spare key, give copy to neighbor
Same thinking applies to cybersecurity!
Key Takeaways ✅
- Fix problems AND prevent recurrence - not just band-aids
- The 5 Whys finds root causes - keep asking “why”
- You already use this thinking when things go wrong
- Document lessons learned to help everyone improve
- Good corrective actions make organizations stronger
