What is the meaning of Proper programming
Proper programming of the ports of the company's Web server through detection of IP addresses could be an excellent strategy or solution for preventing every unauthorised access. For example, it is possible to set up a firewall policy that will exclude everything sent to port 80 (that is mostly used by hackers) except those sent to the public Web server. It may, however, be noted that this kind of filtering can only act as a good first level of security.
