Warning banners often work: Here’s how hospitals can use them to ward off hackers

Researchers have found that displaying a warning banner when someone is logging in reduces the frequency of harmful attacks by hackers. The study found that 45% fewer cyberthieves continued to attempt to infiltrate networks after encountering a warning banner. However, the banners were found to be ineffective against hackers using administrative user accounts, such as IT security professionals. The researchers recommend revising the approach and content of the warning messages. Warning banners are just one component of a broader cybersecurity strategy.
