A recent report from the Information Systems Audit and Control Association (ISACA) states that employees accessing social media at work expose their company's systems to security risks.
In a report entitled 'Social Media: Business Benefits With Security, Governance and Assurance Perspectives', ISACA listed malware, brand hijacking, lack of content control, non-compliance with rules over record keeping, and unrealistic expectations of Internet performance as the five major risks businesses faced from social media.
The ISACA says that because both Facebook and Twitter aren't tied to specific hardware, and require no software to be downloaded, employees could work around a company's security systems to view the sites - and unwittingly expose its systems to security threats.
In a statement to CNet, Robert Stroud, international vice president of ISACA, said: “Historically, organizations tried to control risk by denying access to cyberspace, but that won't work with social media. Companies should embrace it, not block it.”
