Finding and Fixing Website Security Vulnerabilities

#The problem

The sites had outdated plugins, unpatched software and misconfigured server settings. Any of these could lead to a takeover, a data leak or a "dangerous site" warning in search engines.

#What I did

• Ran security scans on the sites and servers and listed outdated versions, open ports, weak settings and known vulnerabilities.
• Ranked the findings by risk and closed them starting with the most critical.
• Updated software, plugins and dependencies, and removed unused ones.
• Protected forms and login areas against abuse and restricted access to admin panels.
• Fixed SSL/TLS settings and security headers, and hardened the server.
• Set up regular backups and update tracking, and delivered a clear report of what was done.

#The result

Known vulnerabilities are closed and the sites are up to date and monitored. If something goes wrong, they can be restored from backup quickly.
