What are YOUR go-to Git commands?

Hollywood convinced everyone that cybersecurity = guys in hoodies hacking mainframes. 🧑‍💻❌

Reality:
Cybersecurity is 100% about managing RISK. 🛡

Here is the ultimate cheat sheet of the 10 Core Security Concepts every IT professional must know:

1. The CIA Triad
Confidentiality. Integrity. Availability. If one falls, the whole system breaks.

2. Principle of Least Privilege (PoLP)
Default to NO. Give users the bare minimum access needed to do their jobs. Stop giving admin rights to everyone.

3. Defense in Depth
No single tool will save you. Layer your security: Firewalls + IAM + Encryption + Monitoring.

4. Zero Trust Architecture
Never trust, always verify. Yes, even if they are already inside your corporate network.

5. MFA is Mandatory
Passwords are weak. If you aren't enforcing OTPs, biometrics, or hardware keys, you are a sitting duck.

6. Encryption Everywhere
Protect Data at Rest AND Data in Transit. HTTPS is not optional; it's the absolute baseline.

7. Patch Management
Zero-days get the headlines, but unpatched 3-year-old vulnerabilities cause the actual breaches. Update your systems.

8. Logging & Monitoring
You can't secure what you can't see. Log everything, alert on anomalies.

9. Incident Response (IR)
Stop asking "What if we get hacked?" Start planning for "When we get hacked, what is our immediate first step?"

10. The Human Element
The most dangerous vulnerability isn't in your code. It's someone clicking a phishing link.

Security isn't a software you buy. It’s a culture you build. 🧠
