A remote access VPN typically uses IPsec or Secure Sockets Layer in order to authenticate the communication between network and device. To do so, it uses a « secret key » (or key-value pair) which is kept secret and cannot be recovered. By having the secret key, the client can communicate securely with the server.

You may think that to protect a remote access VPN from the network, you can simply add a firewall rule to it, but firewall rules only allow traffic on a specific IP address. In reality, an attacker can simply open up multiple ports, thus allowing any connection to reach your VPN. Even if you disable port forwarding on your router, your connection to the internet will remain unaffected, also there are services such as Fortinet online that offer great option for VPN connections.

VPNs that are offered as free, for example, typically have no security at all and you should not use them.

Another important issue, which we will cover in more detail in the following section, is that if you have a compromised router, then it can be used to spy on your internet traffic. When your router is compromised, it becomes the gateway to your entire internet, and it’s possible that the attacker could see any of your traffic, even traffic that isn’t encrypted, just because they can see the network itself. And since your router will be connected to the outside world, anything your attacker sees can be used to break the security of your network as a whole. The final major concern is that if you are using your router at home, you should avoid allowing it to act as a wireless access point in your home, because your home WiFi security is severely lacking. In the home, a WiFi access point is a wireless access point, but it is often hidden, not attached to your router or access point and is not connected to your home network in any way. This gives your home network complete privacy, and does not allow any of your neighbors, friends, or family members to connect.

In your office, a WiFi access point is simply a wireless access point. You need to attach it to your access point, so the access point is « connected » to the internet, and your wireless router is also « connected ». You can see in the diagram below that a device with a wireless network adapter attached to the access point is connected to the Internet, as well as connected to your wireless router. If you attach a device without a network card, the device will not be connected to the network, nor will it be connected to your wireless router, making it an « unplugged » device.

As you can see from the above diagram, an app can take advantage of this functionality, so you can even take advantage of the Android Auto feature of the Google Chrome browser.

While this may be new to you, it’s an excellent feature. Google has been working for a while now to bring the Android Auto feature into the stock version of Android, which is why we’re seeing it in stock Android devices. It also allows for a number of additional features to be implemented in the future, including in-car streaming and vehicle-to-vehicle (V2V) capabilities.

As mentioned, Google just unveiled Android Auto’s new « smart-speaker » features at Google I/O. The new feature allows Android Auto speakers to listen for your commands and respond back in an instant, as seen below.

The smart speaker features are very similar to the Google Home and Alexa’s Echo products, although the new features will require an update to the latest version of Android.
