Cyber Tip: Segment your administrative network and separate privileged access.
Keep domain controllers, jump servers, and management systems separate from user workstations.
Isolation limits lateral movement and protects privileged credentials.

Cyber Tip: Patch your third-party software.
Attackers don’t always need zero-days, just an old plug-in or unpatched tool.
Centralize patching, remove legacy apps, and stay current.
Every unpatched tool is a potential entry point.

Cyber Tip: Close what you don’t use. Unused ports and services expand your attack surface and invite scanning or exploitation. Disabling them keeps your network lean, secure, and harder to breach.

Cyber Tip: Keep an eye on outbound traffic. Attackers often use it to exfiltrate data or maintain control of compromised systems. Reviewing outbound connections helps you detect and contain threats before sensitive data leaves your network.

Cyber Tip: Review your PowerShell logs regularly. Attackers often abuse built-in tools like PowerShell to run commands, move laterally, and hide activity. Detailed logging helps spot unusual scripts or commands that may signal an intrusion before it spreads.

Cyber Tip: Check file hashes before installing or running downloads. Verifying the SHA256 or MD5 ensures the file hasn’t been tampered with and matches the official source. This quick step helps prevent malware from slipping in through fake or modified installers.
