A worm infection can lead to network congestion, system slowdowns, and the spread of additional malware, often resulting in significant operational disruptions.
- How can organizations protect against worms?
Organizations can protect against worms by keeping software and systems up to date with security patches, using firewalls, and implementing strong network segmentation.
