BHJ suggests security and backup policy

Manage User Access to protect a system from scam or hack by unauthorized users. Assign permissions for usage like WordPress allow different levels of access.
Use SSL Certificate to establish secure, encrypted connection between your website and a visitor’s web browser. It gives assurances to visitors that your site takes privacy and security seriously. And, if you are storing login, personal information or processing payments then SSL is a must.
Plan Backup Policy
Backup your website both locally and online. Depending upon the usage, plan site backups.
Having precaution is good.
Update Softwares
To patch up vulnerabilities and security flaws, update your software as it becomes available.
