Quick Summary

IoT Kya Hota Hai?

IoT ka full form hai:
Internet of Things

Simple language me:
Aise devices jo internet se connected hote hain aur data share karte hain.

Examples of IoT Devices

✔ Smart TV
✔ Smart watch
✔ Smart bulb
✔ CCTV cameras
✔ Smart refrigerator
✔ Alexa / Google Home
✔ Smart locks

Ye sab internet ke through communicate karte hain.

IoT Security Kya Hai?

IoT security ka matlab hai:

Smart devices aur unke data ko hackers aur cyber attacks se protect karna.

Simple line:

“Smart devices ko secure rakhna = IoT Security”

IoT Devices Kaise Kaam Karte Hain?

Basic Process

1. Device internet se connect hota hai
2. Data collect karta hai
3. Cloud ya app ke through control hota hai

Example:

Smart CCTV:

✔ Camera record karta hai
✔ Mobile app me live view dikhata hai

IoT Security Important Kyun Hai?

Aaj smart devices:

✔ Personal data collect karte hain
✔ Audio/video record karte hain
✔ Home systems control karte hain

Agar hacker access le le:

• ❌ Privacy risk
• ❌ Data theft
• ❌ Home security danger

IoT Devices Hack Kaise Hote Hain?

1. Default Passwords

Bahut log device ka default password change nahi karte.

Example:

admin / admin

Hackers easily access le lete hain.

2. Weak WiFi Security

Weak WiFi = easy entry point
