Over $50 billion was spent shopping online last year and it is hardly surprising that criminals want a share of the action. No businessman or woman in his or her right mind would leave a shop unattended, unlocked and without an alarm and most take precautions to protect their virtual shops too but not to the same degree of security. Many businesses do little more than install a firewall and antivirus and anti-spyware software and they believe this is all the security that is required. But the more recent developments in online threats are no longer guaranteed to be excluded by the most commonly available security software. Retailers should take professional advice on the system and consider redirecting all of their inbound and outbound traffic to web security specialists who scan all traffic and block threats. Extra special care needs to be taken with the management of systems involved in the handling of payments by credit cards.
