Techopedia Explains System-Level Security

System-level security is part of a multi-layered security approach in which information security (IS) is implemented on an IT infrastructure’s different components, layers or levels. System-level security is typically implemented on end-user computer and server nodes. It ensures that system access is granted only to legitimate and trusted individuals and applications. The key objective behind system-level security is to keep system secure, regardless of security policies and processes at other levels. If other layers or levels are breached, the system must have the ability to protect itself.

Methods used to implement system-level security are user/ID login credentials, antivirus and system-level firewall applications.
