Small businesses may lack the expertise to identify and deal with computer security incidents (Williams & Manhcke 2010), making them an attractive target for online offenders (Verizon 2011). An overview of some of the threats faced by small businesses, including the nature of the threat and potential outcomes, is provided in the following section. Scenarios include malware infection, wireless internet misuse and session hijacking, online fraud, compromised websites, denial of service attacks, phishing, spear phishing, unauthorised access and risks associated with cloud computing. While this overview is not exhaustive, it aims to increase awareness of the types of vulnerabilities small business operators may face.
