Building a Secure House: Understanding the Difference Between Software Testing and Penetration Testing,
Software Testing: Makes sure the house is built correctly and works as planned (lights turn on, doors open, etc.). They check for bugs and defects like leaky faucets (improper functionality) or uneven floors (bad user experience).
Penetration Testing: Tries to break into the house like a thief (ethical hacker) to find any weak spots (vulnerabilities) that real criminals could exploit. They might discover unlocked windows (security flaws) or weak walls (exploitable vulnerabilities).
