Social media is an ever-present area of most of our lives and makes up a large portion of user activity on the web on a daily basis. Knowing how to use social media safely is key to protecting yourself from cyber-attacks online.
Be careful what you share – an attacker could be watching!
New employers may also use social media to find out about you.
Most people will have multiple social media accounts: Facebook, Twitter, LinkedIn, Instagram, Snapchat … the list goes on. Most businesses will also have the same. It is important to use social media as it is a powerful tool for staying in touch with friends, colleagues and even clients. However, if used incorrectly it can cause issues.
Posting in isolation
When you post on a platform, it is typically a small update about something seemingly insignificant. Then a photo is shared on another platform and so on. This can be used by attackers to gain lots of knowledge about a person or business. They can add up all these snippets and link together posts from multiple platforms. Some of the biggest platforms have been around for ten years – this is a lot of data about a single person that can be investigated.
Know what’s public
One of the most important things about social media platforms is for users to know what is public, what can be seen by friends and what is private. All large platforms have Security Settings and Privacy Settings options. You should double check these settings to make sure you know what can be seen. If you are a parent and you set up pages for your families or children make sure you have checked the settings and they are set to an appropriate level.
