Force everybody to have to strengthen the safe protection of the network system of one's own computer, guard enterprise's network according to the safety regulation that the system administrator establishes, offer the strong one , use strobe , information filtering , flow controlling , such functions as the network intercepts . A other one is it control VPN , identity authentication , virtual net bridge , network address change , offer perfect security establishment to visit, go on through high-performance network core function controlled to visit I is it is it realize to come further to determine. The system has adopted VB to manage interfaces , the systematic function strong in management , complicated through the ocular , apt to use interface. The interface hits culture completely, it is simple and direct to operate , really make to measure. Thus reduced their attack of enterprises greatly In fact,the protection of multiter firewalls have becomed the main ways Current online security. |
