Network Security Kya Hai?
Network security ek aisa process hai jisme aap apne computer network ko unauthorized access, misuse, ya attacks se protect karte ho. Simple words mein: Jaise aap apne ghar ko lock karte ho taaki chor na ghus sake, waise hi network security aapke digital "ghar" (jaise Wi-Fi, office LAN, ya cloud network) ko hackers se bachati hai.
In technical terms, network security includes hardware, software, and policies jo data transmission ko secure karte hain. Yeh OSI model ke layers par kaam karta hai, jaise physical layer se leke application layer tak.
Kyun Important Hai?
Aaj kal, har cheez online hai – banking, shopping, work from home. Ek chhota sa breach (attack) aapka data leak kar sakta hai, financial loss ho sakta hai, ya even identity theft. Statistically, 2025 mein cyber attacks 15% badh gaye hain. Isliye, network security jaan'na zaroori hai, especially if you're a student, professional, or business owner.

Network Security Ke Prakar
- Firewall Protection: Yeh ek barrier hai jo incoming aur outgoing traffic ko monitor karta hai. Jaise ek security guard jo check karta hai ki kaun andar aa raha hai.
- Intrusion Detection System (IDS) and Intrusion Prevention System (IPS): IDS attacks ko detect karta hai aur alert bhejta hai, jabki IPS unhe block bhi kar deta hai.
- Virtual Private Network (VPN): Public Wi-Fi par safe browsing ke liye VPN use karo. Yeh data ko encrypt karta hai.
- Antivirus and Anti-Malware: Yeh software viruses, worms, trojans ko scan aur remove karte hain.
- Access Control: Role-Based Access Control (RBAC) se ensure karo ki sirf authorized users hi access karein.
Network Ke Common Khatre
- Malware Attacks: Viruses jo files corrupt karte hain.
- Phishing: Fake emails se credentials churaana.
- DDoS Attacks: Distributed Denial of Service, jisme website ko overload karke down kar diya jaata hai.
- Man-in-the-Middle (MITM): Hacker beech mein aa kar data intercept karta hai.
- Zero-Day Exploits: Unknown vulnerabilities jo pehle se attack ho jaati hain.
Network Secure Karne Ke Tips
- Strong Passwords: Kam se kam 12 characters, with numbers, symbols. Password managers use karo.
- Regular Updates: Software aur firmware ko update rakho.
- Multi-Factor Authentication (MFA): Sirf password nahi, OTP ya biometrics add karo.
- Network Segmentation: Important data ko alag segment mein rakho.
- Monitoring Tools: Tools jaise Wireshark se traffic monitor karo.
- Employee Training: Sabko aware karo phishing ke baare mein.
