This booklet has been produced by the Metropolitan Police Fraud and Linked Crime Online (FALCON) team to assist you in taking the necessary steps needed to protect your business and customers. With limited resources and turbulent economic conditions SMEs may prioritise innovation and growth over online security and risk. These issues are often seen as expensive, burdensome and time consuming. It is important these areas are recognised and assessed and companies are aware of the risks they face from cyber criminals. This booklet aims to identify common types of cybercrime and the ways you can protect yourself from them. It is not an exhaustive list, in what is an ever changing landscape, but by following the advice given, you can improve your protection of the systems and your knowledge of your staff using them.
