The recent acquisition of Red Canary by Zscaler marks a significant move in the Managed Detection and Response (MDR) space. Historically, MDR services have faced challenges in adoption, with even established players like Mandiant (now part of Google Cloud) struggling to maintain momentum. This consolidation highlights the evolving cybersecurity market, where integration and scalability are becoming critical.
You Should Know:
Key MDR & Threat Detection Commands
To stay ahead in threat detection and response, security teams should be proficient in the following tools and commands:
Linux-Based Threat Hunting
1. Auditd for Real-Time Monitoring
sudo auditctl -a always,exit -F arch=b64 -S execve -k process_execution
Tracks process execution for suspicious activity.
2. YARA for Malware Detection
yara -r malware_rules.yar /path/to/scan
Scans files using custom or community YARA rules.
3. Zeek (Bro) for Network Analysis
zeek -i eth0 local
Captures network traffic metadata for anomaly detection.
Windows Incident Response
1. Sysmon for Advanced Logging
Get-WinEvent -LogName "Microsoft-Windows-Sysmon/Operational" | Where-Object {$_.ID -eq 1}
Lists process creation events.
2. KQL for Microsoft Sentinel Queries
SecurityEvent | where EventID == 4688 | project CommandLine, ParentProcessName
Extracts process execution details from Windows logs.
3. PowerShell for Rapid Triage
Get-Process | Where-Object { $_.CPU -gt 90 } | Stop-Process -Force
Kills high-CPU processes (useful for stopping malware).
Cloud & Zscaler-Specific Commands
1. Zscaler API for Threat Intel
curl -X GET "https://api.zscaler.com/v1/threatIntel/feeds" -H "Authorization: Bearer YOUR_API_KEY"
Retrieves threat intelligence feeds.
2. AWS GuardDuty Findings Export
aws guardduty list-findings --detector-id d1a2b3c4d5e6f7g8h9i0j1k2l3m4n5o6p
Lists security findings in AWS environments.
Automated Response with SOAR
Integrating MDR with SOAR platforms like Splunk Phantom or Palo Alto XSOAR allows automated playbooks. Example:
def isolate_host(ip):
requests.post(f"https://api.soc-tool.com/isolate/{ip}", headers={"Auth": "API_KEY"})
What Undercode Say
The cybersecurity market is undergoing rapid consolidation, with Zscaler’s acquisition of Red Canary signaling a push toward integrated security platforms. Teams must adapt by mastering hybrid (cloud + endpoint) detection techniques. Expect more AI-driven MDR solutions and tighter SIEM-MDR integrations in 2025.
Prediction
- More MDR acquisitions by cloud security vendors (e.g., CrowdStrike, Palo Alto).
- Rise of AI-augmented threat hunting, reducing reliance on human analysts.
Expected Output:
A hardened security posture combining:
- Zscaler’s cloud enforcement + Red Canary’s endpoint visibility.
- Automated response scripts (e.g., AWS Lambda + Zscaler API).
- Cross-platform threat correlation (Linux + Windows + Cloud).
