Matt Walmsley, Director EMEA at Vectra industry unlocked 44 H The abundance of data in the possession of healthcare organisations makes them a ripe target for cybercriminals. Matt Walmsley, Director EMEA at Vectra, tells us why the industry is so targeted and why visibility is crucial for staying one step ahead of attackers. Healthcare data has long been one of the favourite targets for cyberattackers. A set of medical records can provide a wealth of data for criminals to conduct fraud or launch more effective targeted attacks. Ironically there have been so many healthcare breaches that the value of an individual data set has dropped significantly in recent years, but medical data is still a basic commodity in the underground cybercriminal economy. Low hanging fruit The healthcare industry has an unfortunately well-founded reputation as a softer target. A combination of factors including legacy equipment, stretched resources and funding constraints mean the industry often falls behind when it comes to keeping systems up-to-date and secure. Organisations on the frontend of healthcare also face unique security challenges due to the fact their main priority is treating patients and saving lives. This makes it far more difficult to manage the downtime required to keep systems updated and secured – even a few hours of downtime can impact lives – so it’s common to find systems running outdated software and lagging behind on patches that would address common exploits. The connectivity dichotomy Ironically, healthcare providers are also under pressure to invest in the latest smart medical technologies. These connected devices can help to deliver a more efficient and responsible environment that helps provide a higher level of clinical care while also reducing costs. However, connected devices also present an easy target for cyberattacks. Clinical imperatives often trump technical security consideration. It’s common to find that smart medical devices have been deployed without any IT or security planning and their network behaviours, update capabilities and vulnerabilities are often not well understood. These concerns are common in every industry where Internet of Things (IoT) devices are used, but the issue is especially pressing in the medical field, where patients’ lives may be directly at stake. A recent report found that a widely used series of connected anaesthetic machines could be vulnerable to attack, enabling a threat actor to inject overdoses or disable warning alarms among other potentially fatal activity. Any new device added to the network – whether it’s a smart MRI machine or a Wi-Fi enabled infusion pump – also increases the potential attack surface. This is exacerbated by the large number of visiting devices that are connected to the typical hospital’s networks. Patients and their visitors, visiting physicians and specialists working at multiple sites, medical students and many other third parties will constantly be connecting to the network.
