Security Awareness Tip


Social media platforms create an avenue for people to connect and share information with each other over the internet.

These include wikis, blogs, social networking sites such as Facebook, Twitter, LinkedIn, Google Plus, Instagram, Snapchat, Tumbler, WhatsApp etc.Â

These websites can however pose a threat to individuals, ranging from young kids, teenagers and even adults, all who have access to the social networking sites and hence are susceptible to a myriad of threat actors.

It is therefore important for society at large, beginning with the basic unit, the family, to implement sound security practices and create necessary security awareness for children so as to reduce the exposure & risk associated with social media platforms.

This guide covers what you need to know and issues to raise with kids about living their lives online.
