53 Essential IT Security Tips For Your Digital Business

As IT and the Internet matures we are all becoming much wiser about many of the online threats facing us personally and the organisations where we work.

However, cyber criminals are becoming cleverer and more sophisticated too! New threats, different ways of attacking network and information systems, and more sophisticated malware demand that we keep alert at all times.

Ongoing training for all members of staff across the organisation is your first line of defence. You need to keep them informed about the latest threats and what they should and shouldn’t do when working online.

Having policies in place to deal with staff use of business communications and the Internet whilst they are at work is also a priority. Staff policies should be linked to the contract of employment so that you can instigate disciplinary proceedings should a member of staff deliberately abuse the policy.
