A VPN is the ultimate tool for protecting your internet security and privacy. A VPN does this by creating a secure encrypted tunnel through which your data is routed through the VPN servers to its destination. With strong, unbreakable encryption, your internet traffic won’t be visible to prying eyes. And even if they manage to intercept it, it won’t be of much use as they still need a decryption key to gain access to your data of which they don’t have.
Besides encryptions, when using a VPN, your actual IP address is replaced with a virtual IP address of the server you select. When you access the internet, the web servers and other internet services will only see your virtual IP address and a virtual location. Your real IP address and your actual location won’t be known.
Làm thế nào bạn có thể dễ bị tổn thương?
Ngay cả khi sử dụng VPN, bạn vẫn có thể phát hiện ra rằng quyền riêng tư và bảo mật của mình hoàn toàn không được bảo vệ. Hãy xem bạn có thể dễ bị tổn thương như thế nào trước các mối đe dọa về bảo mật và quyền riêng tư trực tuyến ngay cả khi sử dụng VPN;
- Thiết bị/hệ thống của bạn bị xâm phạm
Your VPN connection will still work normally even if your device is compromised. This means that a VPN will carry out the encryption and its other functions without caring about your underlying problem.
For instance, if your device has malware or you fell for some phishing scam, cybercriminals can gain access to your data even if you have your VPN on. This is because they already have access to your device and using the strongest VPN encryption won’t help you. In this case, always be cyber-aware, use strong, unique passwords, and update your antivirus/antimalware regularly. Also, avoid bad internet behavior.
- Truy cập các trang web độc hại
If you visit an unsecured site or a malicious website, a VPN will still protect your internet traffic from being accessible to prying eyes. What a VPN won’t protect it you against are dangers that come from visiting a malicious site. That’s, a VPN will protect your compromised internet traffic.
Một lần nữa, trừ khi VPN có một số khả năng khác như chặn phần mềm độc hại, hãy tránh truy cập các trang web không an toàn và thực hành hành vi an ninh mạng tốt ngay cả khi sử dụng VPN.
- Mã hóa yếu
This is one of the major factors that make you vulnerable when using a VPN. Cybercriminals such as hackers know to penetrate systems and are relentless in doing so. When you use weak encryption, hackers will try and crack the encryption protocol to get access to your data and other sensitive information.
Most VPNs offer secure encryptions protocols, but still, there are some weaker protocols such as PPTP. This protocol gives you speed but compromises your security.
Để giải quyết các mã hóa yếu, hãy luôn sử dụng các VPN cung cấp mã hóa cấp quân sự như tiêu chuẩn mã hóa AES 256 bit, mã hóa OpenVPN 256 bit, IKEv2 và IPSec. Các giao thức này có mã hóa mạnh mẽ và cũng cung cấp cho bạn tốc độ cần thiết để lướt internet.
- Các vấn đề liên quan đến dịch vụ VPN
Subscribing to a VPN service means you are placing all your trust in the VPN service to protect you against internet security threats and privacy intrusions. Sometimes it’s not the case especially when the VPN service is not reliable. For instance, if you connect to an unsecured VPN server, your internet traffic will be compromised, and you will no longer be secure and private. It’s even worse if the VPN server keeps logs.
Another VPN service problem would be unreliable connections. If your connection to the VPN server keeps dropping every time and there’s no kill switch, eventually your internet traffic will leak to the open internet and be accessible by prying eyes.
