I'm sorry to hear that you're having security issues with your websites. Securing websites is a complex matter, and it requires a comprehensive approach to identify and address vulnerabilities. Here are some general steps you can take to improve the security of your WordPress and Open Journal System (OJS) websites:
Regularly Backup:
Ensure that you regularly back up your websites. These backups should include both the file system state and the database.
Keep Software Up to Date:
Keep both WordPress and OJS up to date. This includes themes, plugins/modules, and the core of the software.
Use Security Plugins:
Install security plugins for WordPress, such as Wordfence or Sucuri. These plugins can detect and block attacks.
Use Strong Passwords:
Use strong, unique passwords for all user accounts, including administrator accounts and database access.
Check File Permissions:
Ensure that file permissions are configured correctly. Files should have only the necessary permissions for operation.
Configure Firewall:
Implement a firewall to block unwanted traffic. This can be done at the server level or through plugins.
Review Custom Code:
If you have custom code (e.g., in themes or plugins), carefully review it for security vulnerabilities. Use trusted sources for themes and plugins.
Monitoring and Logging:
Set up monitoring and logging to detect suspicious activities. Analyzing logs can help identify attacks.
Use SSL:
Implement SSL certificates for both websites to ensure data encryption between the user and the server.
Server Hardening:
Perform server hardening steps to disable unnecessary services and protect the server against attacks.
Website Monitoring:
Utilize website monitoring services to quickly respond to downtime or unusual activities.
Seek Professional Assistance:
If you're having difficulty identifying or fixing security issues, consider seeking professional assistance. An experienced security expert can help analyze and address security vulnerabilities.
