It’s worth exercising some caution when using social media. Not everyone using social media is necessarily who they say they are. Take a moment to check if you know the person, and if the friend/link/follow is genuine. 

Less obviously, you should think about your digital footprint, which is a term used to describe the entirety of information that you post online, including photos and status updates. Criminals can use this publicly available information to steal your identity, or use it to make phishing messages more convincing. You should:

• Think about what you’re posting, and who has access to it. Have you configured the privacy options so that it’s only accessible to the people you want to see it?
• Consider what your followers and friends need to know, and what detail is unnecessary (but could be useful for criminals).
• Have an idea about what your friends, colleagues or other contacts say about you online.
