Website security should be approached with a multi-layered strategy that is used by most Web development services, including using strong passwords, keeping software updated, implementing SSL encryption, using firewalls and malware scanners, and regularly backing up website data. Additional measures can include using two-factor authentication, limiting access to sensitive information, and educating users on best security practices. It is also important to regularly monitor website activity and stay up-to-date on potential threats and vulnerabilities.
