<p><font color="#ff0000"><strong>软件详细信息</strong></font></p><p> 你的网络是否经常掉线,是否经常发生IP冲突?<br/> 你是否担心通讯数据受到监控(如MSN、QQ、EMAIL)?<br/> 你的网络速度是否受到网管软件限制(如聚生网管、P2P终结者)?<br/> 你是否深受各种ARP攻击软件之苦(如网络执法官、网络剪刀手、局域网终结者)? <br/><br/> 以上各种问题的根源都是ARP欺骗(ARP攻击)。在没有ARP欺骗之前,数据流向是这样的:网关<->本机。ARP欺骗之后,数据流向是这样的:网关<->攻击者(“网管”)<->本机,本机与网关之间的所有通讯数据都将流经攻击者(“网管”),所以“任人宰割”就在所难免了。 <br/><br/> ARP防火墙通过在系统内核层拦截虚假ARP数据包以及主动通告网关本机正确的MAC地址,可以保障数据流向正确,不经过第三者,从而保证通讯数据安全、保证网络畅通、保证通讯数据不受第三者控制,从而完美的解决上述所有问题。 <br/><br/> ARP防火墙几大功能<br/> 1. 拦截ARP攻击。<br/> (A) 在系统内核层拦截外部虚假ARP数据包,保障系统不受ARP欺骗、ARP攻击影响,保持网络畅通及通讯安全;<br/> (B) 在系统内核层拦截本机对外的ARP攻击数据包,以减少感染恶意程序后对外攻击给用户带来的麻烦;<br/> 2. 拦截IP冲突。在系统内核层拦截IP冲突数据包,保障系统不受IP冲突攻击的影响;<br/> 3. Dos攻击抑制。在系统内核层拦截本机对外的TCP SYN/UDP/ICMP/ARP DoS攻击数据包,定位恶意发动DoS攻击的程序,从而保证网络的畅通;<br/> 4. 安全模式。除了网关外,不响应其它机器发送的ARP Request,达到隐身效果,减少受到ARP攻击的几率;<br/> 5. ARP数据分析。分析本机接收到的所有ARP数据包,掌握网络动态,找出潜在的攻击者或中毒的机器;<br/> 6. 监测ARP缓存。自动监测本机ARP缓存表,如发现网关MAC地址被恶意程序篡改,将报警并自动修复,以保持网络畅通及通讯安全;<br/> 7. 主动防御。主动与网关保持通讯,通告网关正确的MAC地址,以保持网络畅通及通讯安全;<br/> 8. 追踪攻击者。发现攻击行为后,自动快速锁定攻击者IP地址; <br/> 9. ARP病毒专杀。发现本机有对外攻击行为时,自动定位本机感染的恶意程序、病毒程序;<br/> 10. 系统时间保护。防止恶意程序修改系统时间,导致一些安全防护软件失效。<br/> 11. IE首页保护。防止IE首页被恶意程序篡改。<br/> 12. ARP缓存保护。防止恶意程序篡改本机ARP缓存。<br/> 13. 自身进程保护。防止被恶意软件终止。<br/> 14. 智能防御。 在只有网关受到攻击的情况下,智能防御功能可以检测到并做出反应,保障网络畅通!<br/><script language="javascript" src="../newhuagg/js_ad_show_8.js"></script></p>

病毒成千上万,一个程序对应一种病毒,似乎挺浪费的. 合一到一个杀毒软件里倒是挺不错~
