Method(s) and apparatus are described for use in preventing unauthorised redirection and/or routing of packets transmitted in a communication network. Packets generated by one or more devices in the communications network are intercepted by an apparatus. The intercepted packets are inspected and it is detected whether at least one of the intercepted packets is associated with redirection based on an unauthorised destination. For each intercepted packet, packet and protocol inspection may be used to determine the originally intended destination of the packet and to determine any other destination(s) associated with redirection of the packet. For each intercepted packet, if the any other destination(s) are not associated with one or more authorised destinations corresponding to the originally intended destination, then the intercepted packet is associated with redirection to an unauthorised destination. Those detected intercepted packets associated with redirection based on the unauthorised destination are blocked or corrected. |
