CISA promotes a fresh way to deter cyberattackers: Lie to them

CyberScoop

The Cybersecurity and Infrastructure Security Agency (CISA) has released its first guidance on using decoys, such as honeypots, to combat cyberattacks. This approach aims to mislead attackers by providing false information and diverting them from valuable targets. By deploying these deceptive tactics, organizations can not only detect intrusions more effectively but also buy time to respond to threats. This guidance represents a shift in how organizations can defend against cyber threats, emphasizing the need for creativity in cybersecurity strategies. As cyberattacks become more sophisticated, CISA’s recommendations may help organizations better protect their assets and data.
