Use secure passwords

Enforce strong passwords for all accounts and require periodic password changes.

Regularly update software:

Ensure that the web application is regularly updated with the latest security patches and software.

Use encryption

Encrypt data and communications with SSL/TLS to protect against eavesdropping and man-in-the-middle attacks.

Monitor activity

Use monitoring tools to detect and investigate anomalies in web application activity.
