An administrator is writing into a database and received an error detailed in the exhibit. The two steps to be taken to resolve this are :

- A firewall is used as layered security measure to secure networks and systems.It is most commonly used security measure for enterprise products.
- A server is typical example of physical control. In this it protects actual IT servers, high-end servers, cloud servers and any physical hardware and assets.
- An Application can be used an example of Layer security. Applications like Antiviruses, Vulnerability Scanners, Anti Malware software and Web Application firewall gateways are typical examples
Control Standard is not an example of Layered Security.
