Elastic Security 8.1 introduces enhanced capabilities to protect against emerging threats, such as the Log4Shell vulnerability, by improving visibility into host-based network activity and offering new sources of threat intelligence. The update strengthens defenses for macOS and Windows systems with protections against credential theft and malicious behavior, mapped to the MITRE ATT&CK framework. It also includes a Network Packet Capture integration to provide comprehensive network visibility across different operating systems, aiding in the detection of suspicious activity. New threat intelligence feeds and data integrations from various providers enhance the system's ability to automate detection and improve analysis. The release simplifies detection engineering and endpoint administration by refining the user interface for faster investigation of alerts and more efficient rule management, aiming to reduce alarm fatigue and streamline security operations. Existing Elastic Cloud customers can immediately access these features, while new users have options for free trials and training to explore the platform's capabilities.
