Determine about the Complete and proper security

Complete and proper security configuration and administration is indeed a complex issue. One should think carefully about the security breaches before connecting tothe Internet. One of the simplest and crudest methods could be that too many system administrators connect to the Intranet first assuming that the Internet should be treated as the potentially hostile environment and consider security at a later stage. This method could be highly useful in detecting possible loopholes in the system beforehand.
