Top security tips for email, Wi-Fi and mobile phones

In this blog, the East Midlands Cyber Protect Network offers 26 tips for improving your company's cyber security.



Cyber crime knows no borders and criminals take advantage of the borderless nature of the internet to commit crimes globally.


In an effort to combat this the SafeBorders project was initiated, resulting in the first global safer internet day in February 2004, it was celebrated in 14 countries.


Safer Internet Day (SID) has become a landmark event in the online safety calendar, on the second Tuesday of February each year. It is now celebrated in more than 170 countries across all continents, and reaches millions of people worldwide.


The Internet is a powerful tool with enormous opportunities for learning, enhancing skills and acquiring new knowledge, as highlighted especially during the COVID-19 pandemic.



However, with opportunities come risks and the goal of SID is to raise awareness of the risks.


The pandemic has introduced new challenges to maintain a strong security posture. The reliance on technology is a double edge sword.


On the one hand, it has made the storage, retrieval and manipulation of information remarkably simple opening vast opportunities to provide customer services and exploit market opportunities. On the other hand, it has introduced unparalleled threats to business operations.


Here are some of our top tips for end users and organisations:
