1.2. Explain the security risks pertaining to system hardware and peripherals.
System hardware and peripherals require physical access controls and protections in order to maintain the logical security imposed by software. Without access control over the facility and physical environment, otherwise secured systems can be quickly compromised. Physical protections are used to protect against physical attacks, whereas logical protections protect only against logical attacks. Without adequate layers of protection, security is nonexistent. This section discusses several issues that often lead to security compromise because they are overlooked or deemed nonserious threats.
