As of today, individuals, companies, counties and cities are breathing a sigh of relief that there was minimal impact from last week's WannaCry ransomware attack. One of the most wide-spread cyber-security events in recent years infected hundreds of thousands of computers in over 150 countries and continues to generate front-page news coverage.
Ransomware is a type of malicious software that infects a computer and restricts users' access to it until a ransom is paid to unlock it. For those with old versions of Windows operating systems that had not been updated were the ones at risk for this particular attack.
It would be easy to sit back and move on without using this incident as an important wake-up call. But the continuous threat of ransomware and other forms of malware exists at all times. And while 2015 was a bad year for ransomware attacks, IBM reports that it increased 6000% in 2016. Most alarming is the fact that malware enters our systems by someone opening an attachment or link that usually looks authentic. In the government sector, most at risk are usually smaller counties and cities – including local police and health services.
It appears that most local governments have been quite good at updating and protecting their operating systems. However, the risk is always present and the bad guys are constantly perfecting their craft. Some localities have held off updating their operating systems because of concerns that the newer systems were viewed as being incompatible with some major legacy software.
Organizations that have received ransomware threats were notified that all files will become encrypted and will be destroyed unless a payment is made – often in Bitcoins – not credit cards. This ransomware threat is also impacting personal PCs – some connected to public sector information systems. Most entities wind up paying the ransom as it often relatively cheap compared with the time and cost of restoring systems.
As bad as this recent threat was, it was highly preventable. Here is what you or your IT staff can do to make your computer systems safe and secure:
Cyber-security and protecting government systems and information consistently rank as the number 1 priority for local government IT executives. This most recent attack shows just how vulnerable our IT systems can be. And with the notoriety it has caused, this attack serves as a reminder that cyber-security is no longer just for IT professionals.
Being "security aware" involves everyone within the organization. This most recent scare should be viewed as an opportunity for local government officials to re-examine policies and procedures to protect government networks. When was the last time your security policies were reviewed? PTI recommends your cyber-security plan address each of the following areas:
