Network Security is a practice of prevention and protection against unauthorized intrusions into any large corporate or smaller home network. The SysAdmin, Audit, Network and Security Insitute, or SANS is a private U.S. for-profit company founded in 1989, which specializes in information security, cybersecurity training and certificates. The best way to view network security is not as one line of defense, which if broken everything gets compromised but as a field of battle, which even if invaded the threat can still be isolated, and then expunged from the system without letting them compromise the whole field.
