Virtual Private Network (VPN)
Why in News?
Recently, the District Magistrate of Doda (Jammu & Kashmir) imposed a two-month blanket ban on the use of Virtual Private Networks (VPNs) across the district.
About VPN
- Encrypted Tunnel: A VPN routes your internet traffic through an isolated digital tunnel, scrambling your data so it cannot be read by hackers or third parties.
- IP Masking: It hides your actual Internet Protocol (IP) address, replacing it with an IP address from the VPN server's location.
- Bypassing the ISP: Your online activity bypasses your Internet Service Provider’s (ISP) direct tracking servers, meaning they can only see that you are connected to a VPN, not what websites you visit.
Key Benefits and Uses
- Data Security: Protects logins, passwords, and personal financial information, especially when using untrusted public Wi-Fi networks (e.g., cafes, airports).
- Remote Work: Allows employees and freelancers to securely log into internal corporate systems and access private files from anywhere in the world.
- Bypassing Geo-Restrictions: Enables users and journalists to access region-locked streaming platforms, websites, or communication tools.
- Prevents ISP Throttling: Stops internet providers from selectively slowing down your connection when they detect bandwidth-heavy activities like gaming or streaming.
Limitations & Disadvantages
- Legal Basis: The order was issued under Section 163 of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, citing misuse for unlawful activities, cybersecurity threats, and risks to public order and national security.
- Scope: The ban applies to individuals, institutions, cyber cafés, businesses, and ISPs, except where VPN use is explicitly authorised by the government.
- Not Total Anymore: A VPN does not grant 100% anonymity; your ISP can still monitor the volume of data you send and receive.
- Reduced Speed: Because data must travel to a remote VPN server first, your internet latency may increase, slightly lowering connection speeds.
- No Malware Protection: VPNs do not act as antivirus software; they cannot prevent a device from being infected by downloaded malware, phishing links, or scams.
- Privacy Risks with Free Services: Many free VPN applications track user habits and sell browsing data to third-party advertisers to make money.
