Use cases
Reduce risk, accelerate hunting and investigation, and consolidate existing toolsets with Corelight's complete range of on-prem, cloud, and SaaS-based solutions.
Threat hunting
Replace a standalone IDS with Corelight’s Open NDR Platform
Replace a standalone IDS with Corelight's Open NDR Platform, which delivers IDS alerts integrated with the evidence needed to investigate them.
Identify the early stages of a ransomware attack
Use the rich evidence and detections Corelight generates around RDP, SSH, and SMB traffic to find early warning signs of ransomware, before encryption occurs.
Fingerprint encrypted connections
Fingerprint SSL or SSH connections via the JA3/HASH packages so analysts can identify and track attacker movements across encrypted channels.
Assess the scope of a malware attack
Pivot off a malware hash in Corelight’s files.log to immediately see all hosts that have downloaded the malicious file and then prioritize additional response work such as agent deployment.
Verify containment and remediation
Use Zeek's network logs for conducting post-breach monitoring to look for the recurrence of malware beaconing.
Improve defensibility
Use Zeek's continuous logging across protocols to establish the "ground truth" of what happened historically, minimizing both legal expenses and the scope of disclosure.
Get insights into SSH connections without decryption
Investigate a suspicious SSH connection and see evidence of file transfers and human keystroke activity via insights from Corelight’s encrypted traffic collection.
Find ATT&CKs with Corelight
Corelight's alerts and network evidence help you uncover a wide range of adversary tactics, techniques, and procedures (TTPs) within the MITRE ATT&CK® framework.
Incident response
Get insights into SSH connections without decryption
Investigate a suspicious SSH connection and see evidence of file transfers and human keystroke activity via insights from Corelight’s Encrypted Traffic Collection.
Assess the scope of a malware attack
Pivot off a malware hash in Corelight’s files.log to immediately see all hosts that have downloaded the malicious file and then prioritize additional response work such as agent deployment.
Automate repetitive manual investigations
Turn manual data aggregation tasks into automated investigative playbooks in your SIEM. One SOC built a SOAR playbook around Corelight’s dns.log and reduced their average incident response times by 75%.
Locate PCAP files needed for an investigation
Pivot from the logs of a Corelight-parsed connection directly into the related packets in using precise timestamps and Zeek Community ID appended to Corelight’s conn.log.
Threat Hunting Guide
Learn how to use network traffic data to hunt for:
• Spearphishing attacks
• Automated exfiltration
• Lateral movement
And dozens more additional tactics and techniques.
Threat detection
Detect SSH client bruteforce attacks
Discover when a client attempts to authenticate beyond a pre-configured threshold and then successfully authenticates.
Detect hidden C2 server communications
Uncover live C2 communications via Zeek’s dpd.log when an attacker attempts to disguise their C2 traffic in a purported SSL connection.
Detect lateral movement
Detect lateral movement in MITRE ATT&CK related to SMB and DCE-RPC traffic, such as indicators targeting Windows Admin Shares and Remote File Copy. Stream Zeek logs to the Real Intelligence Threat Analytics (RITA) tool to create a daily report of potential beaconing activity.
Detect off-port protocol usage
Use Zeek’s deep protocol parsing capabilities to identify network services, such as HTTP or DNS, running on non-standard ports.
Fingerprint connections for fraud detection
Create custom Zeek logs to fingerprint connections and identify issues like API fraud and account takeovers.
Investigate unauthorized SMB file access
Use Zeek’s SMB logs as a source of evidence to document end user access to a sensitive SMB file share without authorization.
Data enrichment
Enhance traffic monitoring with local context
Use the Zeek Input Framework to append internal server names and IT contact information fields to the conn.log to accelerate investigations and
remediation workflows.
Enhance DNS visibility
Use Zeek’s dns.log—which contains both queries and responses—to access forensic information server logs can’t provide, due to a lack of detail.
Identify vulnerable software
Use Zeek’s software.log to identify outdated or vulnerable software, such as Java or Flash, running in an environment.
Flag Cyrillic keyboard usage
Monitor Zeek’s rdp.log to identify the use of Russian character set keyboards in an environment, which could signal unusual behavior.
Fingerprint connections for fraud detection
Create custom Zeek logs to fingerprint connections and identify issues like API fraud and account takeovers.
Investigate unauthorized SMB file access
Use Zeek’s SMB logs as a source of evidence to document end user access to a sensitive SMB file share without authorization.
Network operations
Create inventories of connected devices
Inventory network-connected devices and their services without needing to install host agents, and use Zeek’s software.log to monitor BYO software used by employees.
Monitor risky SSL certificates
Monitor self-signed and expired (or soon-to-expire) certificates via Zeek’s ssl.log.
Troubleshoot a load balancer issue
Diagnose a load balancer performance problem that is difficult or impossible to replicate in a lab environment via evidence gathered from Zeek’s network logs and end finger pointing between security and network operations teams.
