Of course none of them can be labelled as secure protocols (TCP nor UDP). But in a context which should be some dialogue in or packet exchange between two nodes, TCP can be considered more secure. This assert is made upon de premise that it is easier spoofing the source IP Addr if there is not packet exchange, because if not, the attacker need a MIM attack which must impact the victim and also any other intermediate nodes (like ISP routers in an Internet based scenario). This change the context of an attack from one targeted to a multi-targeted attack shifting difficulty. Regards Daniel Largacha Lamela Departamento de Gerencia de Riesgos y Operaciones.

You can read the RFC for this, but I think that the point is not security,. TCP is conection based and UDP is conectionless When you initiate a TCP transfer after every packet that is sent ans acknowledge one is needed from the receiver, with UDP this is nos necessary, that is the difference between this protocols. paavan.shah () gmail com wrote:
It is said that UDP is considered more vulnerable to spoofing than TCP? Can anyone point me to any document/link which describes TCP is more secure than UDP
