Implementing Privileged Session Monitoring

Implementing Privileged Session Monitoring

Overview

Cybersecurity skill for implementing privileged session monitoring. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "implementing privileged session monitoring"

• "Implements privileged session monitoring and recording using Privileged Access M"

• Deploying or configuring session recording for all privileged access to critical servers and databases

• Meeting compliance requirements (PCI-DSS 10.2, SOX, HIPAA, ISO 27001) that mandate privileged activity monitoring

• Investigating an incident where an administrator or third-party vendor may have performed unauthorized actions

• Implementing real-time alerting for high-risk commands executed during privileged sessions

• Establishing a forensic audit trail of all administrative actions on production infrastructure

Do not use for monitoring standard user sessions or endpoint activity; use EDR/UBA solutions for general user behavior monitoring. Privileged session monitoring focuses specifically on elevated-access sessions.

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• CyberArk PAM Self-Hosted or Privilege Cloud deployment with Digital Vault configured
• CyberArk Privileged Session Manager (PSM) or PSM for SSH (PSMP) installed on a hardened Windows/Linux jump server
• Network architecture where all privileged access is routed through the PSM proxy (no direct RDP/SSH to targets)
• PVWA (Password Vault Web Access) deployed and accessible for session review
• Active Directory integration for authenticating PAM users
• Sufficient storage for session recordings (estimate: 50-250 KB per minute for RDP, 5-20 KB per minute for SSH)
• Alternatively for open-source: Teleport, Apache Guacamole with session recording, or script/ttyrec for Linux

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}

1. Assess Requirements — Evaluate current environment and define privileged session monitoring implementation requirements.
2. Design Architecture — Plan the privileged session monitoring architecture, including components, integrations, and data flows.
3. Configure Components — Set up and configure each privileged session monitoring component according to best practices.
4. Test Integration — Validate that all components work together. Run functional and security tests.
5. Deploy to Production — Roll out the implementation with monitoring and rollback capabilities.
6. Validate and Document — Verify the implementation meets requirements. Document configuration and runbooks.

Tools

• Configuration Management — Infrastructure as code and automation
• Monitoring Stack — Observability and alerting
• Documentation Platform — Runbooks and architecture docs

Process

1. Plan — Define infrastructure requirements, security constraints, rollback strategy
2. Implement — Configure resources, apply security best practices, test in staging
3. Deploy & Monitor — Roll out to production, verify health checks, set up alerting

Verification

• All privileged session monitoring procedures executed completely and documented
• Findings validated against multiple data sources
• False positives identified and filtered
• Results documented with evidence and timestamps
• Recommendations provided with risk-based prioritization
