Introduction:
As security operations centers (SOCs) grapple with alert fatigue, artificial intelligence has emerged as a force multiplier—but one‑size‑fits‑all models often miss the mark. Panther Labs, a leader in cloud‑native security, now offers per‑user AI customization, enabling analysts to tailor threat intelligence outputs to their preferred language, tone, and technical depth. This evolution transforms generic alerts into actionable insights, bridging the gap between raw data and human decision‑making.
Learning Objectives:
- Understand Panther AI’s customization capabilities for security operations.
- Implement per‑user customization to tailor threat alerts and response language.
- Deploy custom detection rules and integrate Panther with existing SIEM and cloud environments.
You Should Know:
1. Setting Up Panther AI Customization Profiles
Panther’s AI allows each user to define how threat information is presented. To create a profile:
1. Log in to the Panther Console and navigate to Settings → AI Customization.
2. Click Create New Profile.
- Define the Tone (e.g., “technical,” “executive summary,” “forensic detail”) and Language preferences.
- Associate the profile with specific user roles (e.g., SOC analysts, threat hunters, CISOs).
- Test by triggering a sample alert—observe how the same finding is described differently based on the profile.
Why it matters: Tailored outputs reduce misinterpretation and speed up incident response.
2. Writing Custom Sigma Rules for Threat Detection
Panther supports Sigma—a generic signature format—to create detection logic.
1. Write a Sigma rule to detect suspicious PowerShell execution:
title: Suspicious PowerShell Download logsource: category: process_creation product: windows detection: selection: Image|endswith: '\powershell.exe' CommandLine|contains: 'Invoke-WebRequest' condition: selection
2. Use Panther’s Sigma converter (panther-cli sigma import) to translate the rule into a Panther‑compatible Python detection.
3. Deploy the rule via the Panther UI or CLI, and enable it for your log sources.
Pro tip: Regularly update Sigma rules from open‑source repositories to catch emerging threats.
- Integrating Panther with AWS Security Hub via API
To enrich AWS Security Hub with Panther’s findings:
- Generate an API key in Panther under Settings → API Keys.
2. Use `curl` to send a test finding:
curl -X POST https://api.panther.com/v1/findings \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"id": "test-001",
"title": "S3 Bucket Public Read",
"severity": "HIGH",
"resource": "arn:aws:s3:::example-bucket"
}'
3. Configure a webhook in AWS Security Hub to receive Panther alerts via Amazon EventBridge.
4. Verify integration by checking Security Hub’s Findings panel.
Security note: Rotate API keys frequently and restrict permissions to the minimum required.
4. Customizing AI Alert Descriptions with Python Scripts
For advanced users, Panther’s API allows programmatic adjustment of AI outputs.
1. Write a Python script that fetches recent alerts and modifies descriptions based on severity:
import requests
api_key = "YOUR_API_KEY"
headers = {"Authorization": f"Bearer {api_key}"}
Fetch recent alerts
alerts = requests.get("https://api.panther.com/v1/alerts", headers=headers).json()
for alert in alerts:
if alert["severity"] == "CRITICAL":
new_description = f"[bash] {alert['title']} – Immediate investigation required."
payload = {"description": new_description}
requests.patch(f"https://api.panther.com/v1/alerts/{alert['id']}",
headers=headers, json=payload)
2. Schedule the script via cron (Linux) or Task Scheduler (Windows) for continuous customization.
Benefit: Automate the enrichment of alerts with context from external threat intelligence feeds.
5. Hardening Panther Deployment in Cloud Environments
If you self‑host Panther in AWS, follow these hardening steps:
– IAM Roles: Apply the principle of least privilege—ensure Panther’s IAM role only has read access to necessary log sources.
– Encryption: Enable AWS KMS encryption for S3 buckets storing logs and Panther’s database.
– Network Security: Deploy Panther within a private VPC, using VPC endpoints for AWS services.
– Compliance: Run `aws config` to check against CIS AWS Foundations Benchmark.
aws configservice describe-compliance-by-config-rule --config-rule-names CIS-Benchmark-Rule
– Backup: Enable versioning on S3 buckets to protect against accidental deletion or ransomware.
- Leveraging Panther CLI for Log Analysis on Linux
Panther provides a powerful command‑line tool for ad‑hoc queries.
1. Install the Panther CLI:
pip install panther-cli
2. Configure it with your API token:
panther-cli config set api_key YOUR_API_KEY
3. Run a search across your logs:
panther-cli search --query "sourceIp='192.168.1.100'" --start "2025-01-01" --end "2025-01-07"
4. Pipe the JSON output to `jq` for pretty‑printing and filtering:
panther-cli search --query "eventName='ConsoleLogin'" | jq '.[] | {time: .eventTime, user: .userIdentity.userName}'
Use case: Quickly investigate an IP address without opening the web UI.
7. Testing Custom AI Responses with Simulated Attacks
Validate that your AI customizations behave as expected.
- Simulate a brute‑force attack using a tool like `hydra` (in a lab environment):
hydra -l admin -P /usr/share/wordlists/rockyou.txt ssh://target-ip
- Trigger the corresponding Panther rule (e.g., “Multiple Failed SSH Logins”).
- Check the alert in Panther—verify that the AI description matches the tone you set (e.g., technical details for analysts, plain‑language summary for management).
- Adjust the profile if the output deviates, and re‑test.
Best practice: Create a dedicated test environment to avoid impacting production.
What Undercode Say:
- Key Takeaway 1: Per‑user AI customization transforms raw security alerts into actionable intelligence, directly addressing alert fatigue and improving SOC efficiency.
- Key Takeaway 2: Customization must be balanced with standardization to ensure that critical findings are never lost or misprioritized due to overly personalized filters.
Analysis: Panther’s move toward user‑tailored AI reflects a broader industry trend—adaptive security interfaces that mold to the analyst’s expertise and role. This not only accelerates incident response but also democratizes threat hunting, allowing less technical team members to grasp complex threats. However, organizations must implement governance around customization to prevent shadow configurations and ensure auditability. The integration of Sigma rules and API‑driven workflows further solidifies Panther as a flexible platform that can evolve with emerging threats. Ultimately, the combination of AI and user control represents the next frontier in cybersecurity operations.
Prediction: Within two years, AI‑driven SOC platforms will offer fully customizable interfaces where analysts can not only set language preferences but also define custom logic for alert aggregation and prioritization. This hyper‑personalization will empower teams to handle larger volumes of data with fewer false positives. Concurrently, adversaries will begin exploiting these customization layers—crafting attacks that inject misleading language into AI outputs to manipulate analyst responses. Defenders will need to implement strict input validation and anomaly detection on AI‑generated content to counter this new attack vector.
