Web server security and maintenance are essential aspects of keeping your online presence secure and running smoothly. To ensure the security of your web server, it's important to keep the operating system, software, and applications up-to-date with the latest security patches and updates. Adding a firewall and using encryption for data transfers can also provide an extra layer of security. Additionally, monitoring the server's logs regularly and implementing a backup strategy can help to protect against data loss. Finally, limiting access to only authorized personnel can further help to ensure the security of your web server.
