We've all experienced the annoyance of a virus on our home computers. To defend against another attack we keep our computers updated, arm them with the latest antivirus software, and make sure our information is safely stored in second or even third copy on external devices.
The situation is much more serious when a big company's IT security is breached. "The consequences can be far-reaching," says Romain Bourgue, responsible for IT security at ITER. "A virus in an industrial information system can translate into losing the control of a vital piece of equipment like a pump, a lift or a crane. Effective protection of all IT assets is crucial for the entire ITER Project."
When Bourgue joined ITER in 2016, an initial status check of ITER's information system confirmed that it was adequately protected. But, there was no reason to be complacent. "Cyber threats are a constant challenge," he says. "Every day we detect and deter up to 70,000 attacks on our IT systems."
"In addition, of the 60,000 emails received from the outside every day only a tenth reaches ITER email accounts. We reject the remaining 90 percent because of spam or malicious software, so-called malware."
How then do we maintain the high-level protection of ITER's roughly 3,000 computers—including its 600 servers—against this constant barrage of cyber warfare? Just as with your home computer, regular software updates and data backups are the backbone of IT systems protection. But there is always the specter of emerging threats or targeted attacks going undetected. That is why constant monitoring is a key element of cyber security. It helps to detect early signs of a compromise and take proactive actions to prevent a breach.
New threats in the cyber world pop up like mushrooms. It is impossible to predict what the next one will be and where it will strike. So how do you prepare for the unknown? "We are aiming to limit our exposure and control our environment," says Bourgue. "This may at times appear restrictive."
