Managing privileged access is critical to protecting sensitive systems and data. Here are 5 key metrics to monitor and strengthen your Privileged Access Management (PAM) strategy:
- Unused Privileged Accounts: Identify inactive accounts, as they can be exploited by attackers. Monitor last password changes, access key usage, and login activity.
- Failed Login Attempts: Track login failures to detect potential breaches. Pay attention to timing, frequency, and source of failed attempts.
- Privileged Session Length: Monitor session durations to prevent misuse. Use tools to set thresholds, terminate long sessions, and audit activities.
- Off-Hours Account Usage: Analyze account activity outside regular hours to spot unusual behavior. Implement alerts and stricter controls during high-risk times.
- Privileged Commands: Record all commands run by privileged accounts to ensure accountability and compliance.
Key Takeaways:
- 80% of breaches involve privileged credentials.
- Use tools like AWS IAM Access Analyzer or ADAudit Plus for automated monitoring.
- Implement multi-factor authentication to block 99.9% of automated attacks.
- Regular audits and real-time alerts help meet compliance standards like HIPAA and PCI DSS.
These metrics help reduce risks, improve security, and support compliance efforts. Start monitoring today to protect your organization from potential threats.
Privileged Session Monitoring
1. Detecting Unused Privileged Accounts
Inactive privileged accounts are a serious security risk. Studies show that over 10% of Active Directory accounts are inactive, and 52% of public sector accounts haven’t been used in over six months. These dormant accounts can become easy targets for attackers. Using automated tools to detect and address them is a smart move.
For tracking unused privileged accounts, automated solutions are key. For example, AWS IAM Access Analyzer can continuously monitor AWS environments, providing detailed insights about IAM roles and users. In one case, a security team uncovered an "Audit" account with five unused access keys and six roles with unused permissions using this tool.
Here are key metrics to keep an eye on:
- Last Password Change: Identify accounts with passwords that haven’t been updated in six months.
- Access Key Usage: Check the last API activity for each access key.
- Console Login Activity: Track the most recent login date.
- Service Account Activity: Ensure service accounts are only used for their designated purposes.
Admins can use the AWS Management Console to monitor password and access key usage, download credential reports for usage data, and run AWS CLI commands for more detailed insights.
Enhancing authentication methods is another critical step. Adding two-factor or multi-factor authentication can block 99.9% of automated attacks. Keeping a complete inventory of all privileged accounts - whether user, service, or shared - is equally important for both security and compliance. Regular account audits, paired with automated alerts for dormant accounts, help organizations stay compliant with standards like PCI DSS, HIPAA, and ISO 27001.
2. Tracking Failed Login Attempts
Failed login attempts can be an early warning sign of potential security threats. Insider risks alone cost organizations around $16.2 million in 2023. Keeping an eye on failed logins, much like monitoring dormant accounts, is a critical step in identifying risks and strengthening access security.
Key Areas to Monitor
- Login Source Analysis: Look at IP addresses and geographic locations to spot unusual activity.
- Timing Patterns: Pay attention to failed logins during off-hours, which might indicate unauthorized attempts.
Distinguishing between accidental and malicious login attempts is essential. Here's a quick guide:
| Characteristic | Likely Accidental | Potentially Malicious |
|---|---|---|
| Frequency | 1–2 attempts in minutes | Multiple rapid attempts |
| Source | Known office locations | Unfamiliar locations |
| Timing | During business hours | Off-hours or unusual times |
| Username Format | Minor typos | Systematic variations |
"The key to protecting against security logging and monitoring failures is to log all critical security events and monitor them for suspicious activity." – Security Journey
Best Practices for Implementation
- Set up strict lockout thresholds to prevent brute-force attacks.
- Trigger immediate alerts for multiple failed attempts.
- Require stronger authentication measures after failures.
- Investigate any unusual patterns to rule out threats.
A real-world example underlines the importance of proactive monitoring. In the 2013 Target data breach, attackers exploited repeated login attempts that went unnoticed.
Organizations using Active Directory can simplify this process with tools like ADAudit Plus. It provides pre-built audit reports, making it easier to identify threats compared to native AD auditing. This also helps meet compliance requirements for standards like PCI-DSS, HIPAA, and NIST.

3. Measuring Privileged Session Length
Keeping track of session durations is crucial for spotting misuse and ensuring compliance. This is especially important since 70% of data breaches involve privileged account abuse.
Key Monitoring Components
Privileged Session Manager (PSM) tools capture detailed audit logs through multiple methods:
| Audit Type | Captured Information | Purpose |
|---|---|---|
| Video Recording | Full session activity | Provides visual evidence |
| SQL Command Audit | Database operations | Tracks query patterns |
| SSH Keystrokes Audit | Terminal commands | Monitors command sequences |
| Windows Events Audit | Window titles opened | Tracks app usage behavior |
| Universal Keystrokes | All typed input | Captures detailed actions |
Setting Duration Thresholds
To better manage session lengths and reduce risks, security teams should consider these strategies:
- Just-in-time access: Only allow privileged access for the exact time needed to perform tasks.
- Automated session termination: Configure systems to end sessions that exceed predefined durations.
- Real-time monitoring: Actively observe sessions and step in if any suspicious activity is detected.
Adding advanced tools can streamline these processes and improve oversight.
Advanced Monitoring Features
The Privileged Vault Web Access (PVWA) interface simplifies session management. Teams can search and filter session recordings by criteria like username, IP address, commands used, timestamps, or event types.
According to Gurucul's 2023 Insider Threat Report, 54% of insider threats come from credentialed users. To combat this, organizations should connect their PSM tools with threat analytics platforms. This integration allows for real-time risk assessments and automated responses to suspicious activity. Partnering with specialized security providers can also help ensure thorough monitoring and compliance with industry regulations.
4. Monitoring Off-Hours Account Usage
Analyzing off-hours account usage adds an extra layer of security to privileged access management. According to data, 74% of breaches involve lost or stolen credentials.
Defining Off-Hours Access Patterns
Organizations need to set clear guidelines for normal working hours and expected privileged account usage. Here's a breakdown:
| Time Period | Risk Level | Monitoring Requirements |
|---|---|---|
| Standard Hours (9 a.m.–5 p.m.) | Low | Regular activity logging |
| Early/Late Hours (6 a.m.–9 a.m., 5 p.m.–8 p.m.) | Medium | Additional verification |
| Overnight Hours (8 p.m.–6 a.m.) | High | Strict authorization and real-time alerts |
| Weekends/Holidays | High | Mandatory approval and session recording |
Defining these time frames helps identify unusual activity more effectively, similar to tracking login attempts or session lengths.
Implementing Detection Systems
User and Entity Behavior Analytics (UEBA) tools are essential for spotting unusual activity during off-hours. For example, SolarWinds Security Event Manager can:
- Disable suspicious accounts
- Automatically revoke privileged access
- Notify security teams in real time
When anomalies are detected, immediate action is key.
"Privileged accounts are at the root of most data breaches, informing the Who, What, Where, and How questions that follow." – WALLIX
Risk Mitigation Strategies
To reduce risks tied to off-hours access, consider these measures:
- Use dynamic, context-aware access controls
- Maintain whitelists of approved IP addresses for remote access
- Keep comprehensive audit logs
- Set up alerts for multiple failed login attempts outside regular hours

5. Recording Privileged Commands
Tracking privileged commands is a crucial step in creating a complete audit trail and ensuring accountability. By recording these commands, organizations can bolster both security and compliance efforts.
Command Logging Requirements
When it comes to logging, focus on these three critical areas:
| Logging Component | Purpose | Implementation Requirements |
|---|---|---|
| System Events | Monitor logon/logoff and key actions | Enable process creation and command-line auditing |
| Network Activity | Track firewall and access control events | Set up real-time alerts for unusual patterns |
| Application Commands | Log privileged application usage | Use structured formats like JSON for logs |
Implementing Secure Logging
A centralized logging system is key to maintaining data integrity. Use TLS 1.3 to secure log transmissions and encrypt logs at rest. For added protection, store logs in a separate environment from production systems. This setup ensures that all privileged actions are properly recorded and safeguarded.
"Effective monitoring of their use requires continuous visibility and reporting that ties all privileged activity back to a specific user." - Tony Goulding, Author
Real-Time Detection Capabilities
A strong logging system enables real-time anomaly detection. Tools like UEBA (User and Entity Behavior Analytics) can create baselines for normal command usage and flag unusual activity as it happens.
In addition to real-time detection, logs must meet regulatory compliance standards.
Compliance-Driven Monitoring
- SOC 2 Requirements: Maintain detailed audit trails to satisfy SOC 2 standards.
- HIPAA Guidelines: Ensure compliance with HIPAA by including features like file integrity monitoring and configuration assessments.
Best Practices for Log Management
To streamline log management, follow these steps:
- Use role-based access controls to restrict log access.
- Enable real-time monitoring for critical systems.
- Store logs separately from production systems to enhance security.
- Implement indexing for faster log searches.
- Regularly test your logging setup to ensure it’s effective.
Lastly, filter event logs before sending them to SIEM or XDR platforms. This reduces storage and processing costs while retaining essential security data.
Conclusion
Monitoring privileged access is crucial for protecting your organization from potential risks. As David Fairman explains:
"If a privileged account is accidentally compromised or maliciously used, there is a much greater risk to the organisation. It can lead to data loss, system outage, and more. The risk to your environment, if not managed well, can be catastrophic."
By using the right metrics, you can enhance both security and compliance efforts:
| Metric | Security Benefit | Compliance Impact |
|---|---|---|
| Unused Account Detection | Reduces attack exposure | Supports access review requirements |
| Failed Login Tracking | Detects breaches early | Confirms authentication controls |
| Session Length Monitoring | Curbs unauthorized access | Highlights session management |
| Off-Hours Usage Analysis | Spots unusual activity | Proves monitoring practices |
| Command Recording | Creates detailed audit trails | Aids investigations |
These metrics highlight the importance of keeping privileged access tightly monitored. Account compromise remains a major security risk, making such oversight a key part of protecting your systems and ensuring compliance.
