To Ikea Canada’s credit, said Erich Kron, security awareness advocate at KnowBe4, it spotted the kind of data access that many organizations would not have noticed, and by furnishing the information to the Office of the Privacy Commissioner of Canada, allowed potential victims to take steps needed to protect themselves. “Like with their store layouts, spotting when and where data may have been accessed, especially by an internal employee, can lead down an ever-twisting path full of false flags and pointless distractions, often resulting in nothing useful being found.
“Organizations should be careful to periodically confirm the type of data employees can access and should limit it to the least amount needed to perform their job. In addition, penetration tests should be performed to look for vulnerabilities within the network and Data Loss Prevention (DLP) controls enabled to reduce the chance of sensitive data being removed from the network.”
The incident accentuates the threat posed by the “inside job,” said Erfan Shadabi, cybersecurity expert with data security specialists comforte AG. “When we hear of careless handling of sensitive information, we begin to wonder just how secure our own data is within the many different data ecosystems housing and processing it. Employees are usually granted a certain level of trust with enterprise data, even if they don’t have access and rights to all information within the organization. Working from the inside with an implied level of trust means that the inside job has more time to develop and execute an effective exfiltration strategy.
“The answer to counter this threat,” he said, “is to recognize how vulnerable businesses are from the inside and to adopt security stances like Zero Trust, which denies implicit trust to users, devices, and other entities regardless of their location within the network.
“Also, protect all sensitive enterprise data with more than just perimeter security, even if you feel that the impenetrable vault you’ve stored it all in is foolproof. Make sure that data-centric protection such as tokenization or format-preserving encryption effectively obfuscate sensitive information in case internal or external threat actors find their way into your data ecosystem.”The post Ikea Canada tight-lipped on details of breach of security controls first appeared on IT World Canada.
