Web security remains one of the most pressing concerns for IT organizations as recent high-profile cyberattacks have proven that all businesses can be attacked. Because of the sensitive data usually housed, web servers IBM 3rd party support are among the most targeted places in an organization. Securing your web server is just as important as securing your website, web application, and network.
Securing a web server is a tricky operation, but it is certainly possible. Unfortunately, no matter what web server software and operating system you use, out of the box configuration is generally insecure.
The Tips Below Will Help You Improve The Security Of Your Web Server
- Removing unnecessary services
The default operating system settings and configurations are not secure. A typical default installation includes many network services that you will not need in your web server settings, such as remote registry services, print server service, etc. The more services run in the OS, and the more ports are left open, so disable services you are not using.
- Management of permissions and privileges
File and network service permissions that affect the security of the webserver. If the network services software compromises the webserver mechanism, the user can gain access to the account on which the network service is running. For added security, assign the least privilege required to run a specific network service. Also, assign minimum privileges to any anonymous user needed to access the website, web application files, and databases.
- Remove unnecessary modules and app extensions
Apache default installations have a few predefined modules that you probably aren’t using. Disable these modules to prevent targeted attacks against them.
Microsoft’s web server, Internet Information Services, is similar. By default, it is configured to serve a wide variety of application types such as ASP, ASP.NET, etc. The list of application extensions should only include a list of your website or web application extensions. Each app extension should also be restricted only to use specific HTTP verbs whenever possible.
- Web Server Monitoring and Auditing
Ideally, you should keep all logs present on the webserver in a separate area. Network service logs, website access logs, database server logs, and operating system logs should be monitored regularly. Keep log entries as log files usually provide all information about an attempted attack. If you notice suspicious activity in the logs, immediately investigate what is happening.
