Essential CMD Commands for Security and Audit Checks
Hello friends! Have you ever wondered how to enhance your system's security or perform quick audit checks without installing heavy tools?
If you’re using Windows, the Command Prompt (CMD) is a powerful tool that can help you inspect, monitor, and even defend your system with just a few typed commands.
In this post, we’ll walk through some essential CMD commands you can use for security analysis and audit checks. Whether you're a beginner or just brushing up your skills, this guide will make things easy to understand and apply right away!
System Info and User Accounts
One of the first steps in a system audit is understanding the current system and who has access to it.
Here are some key commands:
| Command | Purpose |
|---|---|
systeminfo |
Displays detailed information about the system, including OS version, BIOS, RAM, and patches. |
whoami |
Shows the current logged-in user and domain. |
net user |
Lists all user accounts on the system. |
net localgroup administrators |
Displays users in the Administrators group – crucial for access control. |
Tip: Always monitor who has administrative rights to reduce unnecessary privileges.
Network and Firewall Status
Network monitoring is vital for identifying unusual or unauthorized activities. CMD offers several helpful commands:
| Command | Purpose |
|---|---|
ipconfig /all |
Displays all IP configuration details including DNS, gateways, and interfaces. |
netstat -ano |
Shows all active connections and their corresponding PIDs. |
ping [address] |
Tests connectivity to other hosts – useful for detecting dropped or slow responses. |
netsh advfirewall show allprofiles |
Displays the status of the Windows Firewall for all profiles. |
Keep an eye out for unknown connections in your netstat output – they could be a sign of intrusion.
Active Processes and Services
Keeping track of what's running in the background is essential for performance and security.
| Command | Function |
|---|---|
tasklist |
Lists all running processes with memory usage and PID. |
taskkill /PID [id] /F |
Forcefully stops a process by ID. Use with caution! |
sc query |
Displays active services and their states. |
net start |
Lists all services currently running. |
Suspicious processes or unknown services should be investigated immediately to prevent threats.
Audit Logs and Event Viewer
Windows keeps a detailed record of system activities, which can be accessed via CMD. These logs are essential during audits or incident investigations.
| Command | Description |
|---|---|
wevtutil qe Security /f:text /c:5 |
Displays the last 5 security event log entries. |
auditpol /get /category:* |
Shows current auditing policies on the system. |
eventvwr |
Opens the graphical Event Viewer for detailed log access. |
Reviewing audit logs regularly helps detect failed login attempts, privilege changes, and system modifications.
Common CMD Security Checks
Here are some simple yet powerful security checks every Windows user should run regularly:
net accounts– Checks password policies like max age and lockout settings.net share– Lists shared folders and resources, often a blind spot.dir /s /b *.exe– Searches for all executables. Helpful to spot unknown apps.attrib -H -S /S /D– Lists hidden/system files. Useful for detecting malicious files.cipher /w:C:\– Securely deletes free space to wipe deleted data traces.
Combining these commands gives you a strong foundation for securing and auditing your system using CMD.
CMD Best Practices and Automation
To make security checks more efficient and less error-prone, consider these best practices:
- Create batch scripts to run frequent audits quickly.
- Use logging by appending
> logfile.txtto commands. - Schedule tasks using
Task Schedulerfor daily or weekly checks. - Document everything – knowing when and why a command was run is critical for audits.
- Practice safe usage – double-check commands before executing anything destructive.
By following these tips, you can turn CMD into a proactive security and auditing ally!
