The RSA Conference 2025 highlighted the growing prominence of Agentic Security and AI Agents in cybersecurity. While some veteran security leaders remain skeptical, real-world implementations are proving their effectiveness. Here’s what you need to know about this emerging trend.

You Should Know: Practical Implementation of Agentic Security

Agentic security refers to AI-driven systems that autonomously detect, analyze, and respond to threats in real time. Below are key commands, tools, and steps to experiment with AI-driven security:

1. Setting Up an AI-Based Threat Detection System

  • Use Elasticsearch + Kibana + ML Modules for log analysis: 
    sudo apt-get install elasticsearch kibana
sudo systemctl start elasticsearch
sudo systemctl start kibana
  • Enable Machine Learning (ML) in Kibana: 
    PUT _ml/anomaly_detectors/network_threats
{
"analysis_config": {
"bucket_span": "15m",
"detectors": [
{
"function": "high_count",
"field_name": "source.ip"
}
]
},
"data_description": {
"time_field": "@timestamp"
}
}

2. Automating Threat Response with AI Agents

  • Deploy OpenAI’s API for security automation: 
    import openai</li>
</ul>

response = openai.ChatCompletion.create(
model="gpt-4",
messages=[
{"role": "system", "content": "Analyze this log for suspicious activity."},
{"role": "user", "content": "Log: Failed login attempts from 192.168.1.100"}
]
)
print(response.choices[bash].message['content'])

    3. AI-Powered SIEM Integrations

    • Use Splunk’s AI-driven analytics: 
      splunk add search-command -name ai_threat_detection -python ai_security.py
    • Example Splunk SPL query for anomaly detection: 
      index=firewall | anomaly action=block | table _time, src_ip, dest_ip, action

    4. Linux-Based AI Security Tools

    • Falco (Cloud-Native Runtime Security): 
      curl -s https://falco.org/repo/falcosecurity-3672BA8F.asc | sudo apt-key add -
sudo apt-get update && sudo apt-get install falco
sudo systemctl start falco
    • YARA for Malware Detection: 
      yara -r malware_rules.yar /suspicious_directory

    Prediction: The Decline of Traditional Security Conferences?

    Many vendors at RSA 2025 questioned the ROI of large expo booths, favoring private meetings. This could signal a shift toward virtual cybersecurity summits and AI-driven threat intelligence sharing over physical events.

    What Undercode Say

    Agentic security is not just hype—it’s the next evolution of cyber defense. By integrating AI-driven threat detection, automated response systems, and intelligent SIEM tools, organizations can stay ahead of attackers.

    Key Commands to Master AI Security:

    • Suricata (IDS): 
      sudo suricata -c /etc/suricata/suricata.yaml -i eth0
    • Snort (NIDS): 
      snort -A console -q -c /etc/snort/snort.conf -i eth0
    • MITRE ATT&CK Framework Integration: 
      python3 attack-matrix.py --threat T1059
    • Windows Defender AI Integration (PowerShell): 
      Set-MpPreference -DisableRealtimeMonitoring $false
Start-MpScan -ScanType FullScan

    Expected Output:

    • AI-driven threat detection logs
    • Automated incident response actions
    • Real-time SIEM alerts with AI analysis
