Thus, since the partners can not control the network security policies and activities, then it should be for each of the joint venture to create a DMZ, and the resources they need access to the DMZ in the appropriate place, the internal network does not allow them to other resources visit. 5, turn off unused network server Large enterprise network may also support four to five server send e-mail, and some corporate networks will appear dozens of other servers SMTP port to monitor the situation. The host may have a potential point of attack mail server. So to break one by one web server to be reviewed.
