Tips for Enhancing Website Security
The following list provides a few suggestions that may improve a web site’s security posture. These practices are not intended to be a complete listing of security enhancement measures, and there is no assurance that, if followed, a web site will not be compromised, defaced, or otherwise attacked or disabled.
Configure web server on a host computer dedicated to web server functions; remove all unnecessary services, applications, administrative tools, accounts, pages, files, and directories; change default passwords.
Data and file security
Do not store source code or data on web server; limit the files that can be uploaded; restrict access to directories and administrative tools; regularly review content exposed on the web server; maintain authoritative copies of content and application code in a separate secure location; utilize encryption to protect sensitive information transmitted over the Internet.
Identity and access management
For interactive websites, require users to provide unique identification (such as user ID and password); configure user accounts to access only the information that is necessary to complete the approved function or transaction.
Physical security and maintenance
Physically secure and restrict physical access to the web server; backup the web server on a frequent basis; keep web server current with recommended security patches for the version in use.
Implement anti-virus software and run regular scans for malicious code; implement a DMZ (demilitarized zone or perimeter network) with appropriate firewall to separate public facing web server from the internal network; implement intrusion detection and prevention software to identify suspicious traffic directed at the web server.
Log management and review
Review web server security event logs regularly for suspicious activity; maintain copies of security event logs separate from web server long enough to enable future research if a security incident occurs.
Ongoing review and maintenance
Assess the web server for vulnerabilities on a regular and continuing basis; engage the services of a trusted security consultant to assess the security posture of the web server environment for your specific needs.
