Open and closed social networking services-
Open Networks
Open networks, such as Twitter, Instagram and Pinterest, are designed for you to communicate with the whole world. They don’t make it easy to restrict who sees your posts although it is possible to have some control over this. In general, when using these networks you should assume everyone can see everything you post, everything you like or favourite, and everyone you are connected to.
Closed Networks
Whereas Closed networks like WhatsApp, Snapchat and to some degree Facebook are used by groups of friends or connections to share updates, photos, thoughts etc. with each other. While most of the stuff you post on these networks isn’t accessible to everyone, some of it is. Unintended sharing of personal information in public spaces can have serious consequences. You need to be particularly vigilant when using these networks.
- Multi-factor Authentication- This should be standard security practice for everyone online today. Multi-factor authentication forces anyone logging into an account to supply a code sent to an external device or use other 3rd party software.
- Encryption- is a means of securing digital data using one or more mathematical techniques, along with a password or “key” used to decrypt the information. The encryption process translates information using an algorithm that makes the original information unreadable.
