TCP协议和UDP协议有什么区别？被攻击怎么防御？

TCP（传输控制协议）和UDP（用户数据报协议）是两种广泛使用的传输层协议。尽管它们都在网络上传输数据，但它们在多个方面存在显著差异，这些差异决定了它们各自适用的场景以及面对网络攻击时的防御策略。TCP协议与UDP协议的区别连接性：TCP：是一种面向连接的协议，数据传输前必须先建立连接。这一连接通过三次握手实现，确保双方都已准备好传输数据。UDP：是一种无连接的协议，发送方不需要与接收方建立连接，可以直接发送数据。可靠性：TCP：对数据的可靠性要求非常严格。它通过确认和重传机制确保数据的完整性和正确性。如果接收方未收到数据，发送方会不断重传，直到接收方确认收到。UDP：对数据的可靠性要求较低，不提供确认、重传和流量控制机制。如果数据丢失或损坏，UDP不会进行重传，这可能导致接收方收到的数据不完整。速度和效率：TCP：由于需要建立连接和使用确认重传机制，TCP的传输速度相对较慢，特别是在网络拥堵时，TCP的拥塞控制机制会进一步降低发送速率。UDP：不受拥塞控制的限制，没有连接建立和确认重传的开销，因此传输速度通常更快。数据包大小：TCP：将数据划分为较小的数据包进行传输，并根据网络状况进行调整，没有固定的数据报大小限制。UDP：允许发送方一次性将多个数据包打包成一个较大的数据报进行传输，数据报的大小一般由应用层决定。适用场景：TCP：适用于对数据可靠性要求较高的应用场景，如文件传输、电子邮件、网页浏览等。UDP：适用于对数据实时性要求较高的应用场景，如音频和视频流传输、网络游戏、实时通信等。防御策略TCP协议的防御策略：TCP SYN泛洪攻击防御方法：安装防火墙，过滤可能的恶意TCP数据包。使用TCP SYN Cookie机制，在不存储连接信息的情况下正确处理TCP连接请求。限制TCP连接数，减少攻击的危害。及时更新系统和应用程序，修复已知漏洞。TCP SYN扫描攻击和TCP FIN扫描攻击：防御方法：同样可以使用防火墙进行过滤。关闭不经常使用的服务，减少系统漏洞。使用IDS/IPS（入侵检测系统/入侵防御系统）及时发现并防御攻击。TCP Land攻击：防御方法：检查和过滤具有相同源IP和目标IP的TCP数据包。部署防火墙和入侵检测系统，防止此类攻击的发生。UDP协议的防御策略：UDP洪水攻击和UDP反射放大攻击：防御方法：限制UDP端口的使用，只允许受信任的应用程序使用特定的UDP端口。使用TCP协议代替UDP协议，在需要时利用TCP的拥塞控制和流量整形功能。配置防火墙规则，阻止来自未知IP地址的数据包进入网络。载荷检查和指纹学习：防御方法：对UDP流量进行统计，当流量超过阈值时触发载荷检查，丢弃超过部分的数据包。使用指纹学习技术，动态学习并识别恶意数据包的显著特征，丢弃匹配的报文。关联TCP类服务防范：防御方法：当UDP业务受到攻击时，对关联的TCP业务强制启动防御措施。通过关联防御产生TCP白名单，以确定同一源的UDP流量的走向，只允许白名单内的流量通过。TCP和UDP作为网络传输层的两种重要协议，在连接性、可靠性、速度和效率、数据包大小以及适用场景等方面存在显著差异。了解这些差异有助于在设计和部署网络应用时选择合适的协议。同时，针对不同类型的网络攻击，通过实施有效的防御策略，可以确保网络的安全和稳定运行。

漏洞扫描对系统有损害吗?产生系统漏洞原因

　　面对漏洞会影响到的范围很大，包括系统本身及其支撑软件，网络客户和服务器软件，那么漏洞扫描对系统有损害吗？不少企业在进行漏洞扫描的时候都会担心是不是会造成一些不必要的损害。今天我们就一起来学习下产生系统漏洞原因。 　　漏洞扫描对系统有损害吗？ 　　漏洞是系统在设计时的不足是黑客攻击计算机所利用的通道，所以如果扫描出了问题的话就一定要补好不然你的电脑很容易中毒。各种杀毒软件都有漏洞扫描。 　　系统漏洞分为很多等级，一般的说在微软的网站上定义为严重的都应该及时更新。比如ms06-040漏洞可以远程获得你系统的权限，也就是说如果你没有更新这个补丁的话，可能有些骇客利用这个漏洞来控制你的计算机。如果没有特殊原因的话建议你一直打开WINDOWS的自动更新各种系统漏洞及应用软件漏洞都比较严重危害较大。 　　网络影响：漏扫本身就是一种攻击，请求网络包的频率、数量，对网络和应用造成影响，交换机 / 路由器可能因此宕机； 　　异常处理影响：业务无法正确处理请求包里的特殊输入引发异常宕机； 　　日志影响：每一个 URL 的探测都可能造成一个 40x 或者 50x 的错误日志。 　　产生系统漏洞原因 　　1、编程人员在设计程序时对程序逻辑结构设计不合理不严谨，因此产生一处或者多处漏洞，正是由于这些漏洞，给病毒入侵用户电脑提供了入口。 　　2、编程人员的程序设计错误也是计算机系统漏洞产生的原因之一，受编程人员的能力经验和当时安全技术所限在程序中难免会有不足之处，轻则影响程序效率重则导致非授权用户的权限提升这种类型的漏洞最典型的是缓冲区溢出漏洞它也是被黑客利用得最多的一种类型的漏洞。 　　3、由于目前硬件无法解决特定的问题，使编程人员只得通过软件设计来表现出硬件功能而产生的漏洞会让黑客长驱直入攻击用户的电脑。漏洞会影响到的范围很大包括系统本身及其支撑软件网络客户和服务器软件网络路由器和安全防火墙等。 　　漏洞扫描对系统有损害只是轻微的影响，产生系统漏洞原因有很多，系统在不同的设置条件下都会存在各自不同的安全漏洞问题。因而随着时间的推移旧的系统漏洞会不断消失新的系统漏洞会不断出现。系统漏洞问题也会长期存在。
