Security Tip
by Chris Doggett
What are the most common sources of vulnerabilities that security tests reveal?
Typically security vulnerabilities arise most commonly as a result of inadvertent configuration errors and omissions.
Some of the most common recommendations to counter the vulnerability include:
- Implement and enforce strong passwords (8+ characters with 3 of the 4 character sets)
- Require that all remote users either have security on their computers, use a secure remote access method or have their computers scanned for compliance before allowing them to connect to your internal network (this should include anti-virus, patch levels, and firewall)
- Disable an unnecessary services, especially for external-facing servers
- Establish and adhere to a thorough patch management process and check for deficiencies regularly
- Perform periodic vulnerability scanning to identify issues regularly (monthly is recommended)
- Implement rules on your firewall to restrict both inbound and outbound traffic as much as possible
- Utilize available security logging and auditing, and review / alert on key conditions
Following these basic practices will go a long way to improving your security posture.
