Using a VPN is a great start, but it isnt the only way to protect yourself from hackers online. Try these top tips to help keep your data and devices secure.: Pick password-protected Wi-Fi. When connecting to Wi-Fi, choose networks that have WPA or WP2 passwords for protected access. If the network doesnt require a password, the connection could be open to hackers and other threats. Look for the lock icon. Make sure that the web pages you visit are HTTPS encrypted whenever possible and contain a lock icon in the address bar. Do this by looking at the beginning of the URL you are accessing if the URL starts with HTTP, log out particularly if youre doing something sensitive. Watch for warning signs. SSL and TLS warnings are the messages that pop up in your browser when you come across an insecure connection and its likely that youve clicked through the notification without a second thought. Take a moment to think about what youre agreeing to before moving past the notifications next time because it could mean youre putting your devices and data in danger.

When a client connects through an IPSec VPN, he or she has virtually full access to the network. Clients appear as just another node on the network. IPSec VPNs have been around for a long time. For years, IPSec VPNs were the standard for client access VPNs. SSL VPNs have just begun to grow in popularity fairly recently. SSL VPNs use general SSL traffic over port 443 to establish the VPN connection. This is very useful when a user must initiate a connection from within a protected network. Many networks, especially corporate networks, filter what traffic is allowed to leave out through the firewall. In most cases, however, SSL over port 443 is allowed. SSL VPNs are considered most secure than IPSec VPNs because you have more control over what users can access. Another advantage SSL VPNs have over IPSec VPNs is the fact that most SSL VPNs can provide clientless access.
