- 共享网络性能信息（TCP控制块和拥塞管理模块）
有些信息不应当被共享。例如，TCP顺序号用来防止伪装攻击（spoofing attacks），甚至有关性能参数的共享都会给拒绝服务攻击造成机会[Touch97]。
- 性能增强代理（Performance Enhancing Proxies）
从安全攻击角度看，此类系统扮演了中间人（men-in-the-middle）的角色。因此，必须要特别小心，以避免系统被劫持（hijack）或被滥用（misuse）。
最后的观点不应被轻视：只要中间介质节点进行的操作与其在端对端下不同，就会存在安全问题。这并非专指性能增强代理。应当提前应用基于IPSEC的保护，以使殊如SNOOP模块、头压缩（TCP、UDP、RTP等）、HTTP代理能够参与工作。
一些高层的安全机制（如RTP加密、在TCP负载中进行TLS加密）已经减轻了这个安全问题的影响，然而，协议头仍是可见的，仍可能被通信分析所破解并遭受拒绝服务攻击。
