It is not possible to entirely eliminate vulnerabilities in your application, but you can limit system attacks by hardening your application's operating system, filesystem, and directory. Once attackers can get into your application, they can get root access and orchestrate an attack on the entire infrastructure. It is essential to limit attacks to the application level by restricting the directory by hardening permission. At the process level, restrict memory and CPU utilization to prevent a DOS attack.
Set the right permission at the file, folder, and file partition levels, which is the only requirement for the application to execute. Avoid giving root privilege to the application or their user. You should create a separate user and directory, with only required access for each application. Don't use common access for all applications.
Automate application restart by using tools and avoid a manual approach, whereby users need to log...
