Your Internet Service Provider can potentially see all your information, if you don’t encrypt your traffic. This can be a sensitive issue as your confidential data can be compromised, due to technical vulnerability, and it can result in loss of private information. Let us break down what is visible to your ISP and how to address any problem, both when your traffic is encrypted and unencrypted.
Sites You Visit
The ISP can know the exact sites you are visiting, if they are unencrypted. If the site is using http instead of https, the ISP would be able to track your login details and payment information. Keep an eye on any website you are visiting and don’t visit the ones with invalid SSL certificates. Use a good proxy to stay protected.
Email services without Transport Layer Security encryption is exposed to your ISP. When using Google Mail, it notifies you with a red lock if the sender or recipient does not make correct use of TLS. You can either ask for another email address, or notify the sender. One can also choose to delete their Gmail account.
The ISP may not be interested in knowing what sort of content you are downloading from torrent, but if you are using enough bandwidth, they might choke down your download speeds. Use a virtual private network for safe downloading, without your ISP knowing it.
Is Encryption Enough To Stay Protected?
Even after you are done encrypting your data, your ISP can see the unencrypted metadata following the encrypted web traffic. Based on the nature of the traffic, they can make strong references. Network operators can easily learn about your browsing, by analyzing unique traffic pattern streamed to your device. In simple words, anything from your SleepSense Monitor to Alexa can challenge your privacy by exposing your daily routine.
Connecting devices through a VPN-supported router will make it tough for your ISP to know which device you are using. But you cannot say that it is impossible for an adversary to conclude what sort of traffic you are sending, particularly if you have multiple devices sending out sparse traffic or only have an IoT device. By adding random outbound and inbound traffic into your encrypted traffic, you can scramble the pattern. You will have to use the proxy services to bundle all the traffic together so your Internet Service Provider cannot differentiate between a website, a torrent or a movie. You have to ensure constant traffic exchange, even when you are not around. This is important to avoid traffic spike, when, for instance, you come online at home after work.
Creating a constant stream helps you in creating inbound traffic that covers up any jump in traffic rate. This can generally happen when you switch on your system after coming from work. Run a digital radio broadcast and mute it, or an audio service like Spotify. On the other hand, you can share popular files on file-sharing service, in order to create outbound traffic.
