The invention discloses a firewall policy processing method and device. The method comprises the following steps: pre-creating a corresponding relation between a network security domain topology and acorresponding firewall policy; searching security domain related information associated with target policy information from the above corresponding relation after acquiring an operation instruction of the firewall policy input by a user and the corresponding target strategy information; and then determining whether to execute the operation instruction according to the security domain related information corresponding to the target policy information; if determining to execute the operation instruction, sending the operation instruction and the target firewall policy corresponding to the target policy information to the target firewall, and enabling the target firewall to execute the operation instruction. By using the method disclosed by the invention, a security domain path and the security domain capital information associated with the target policy information can be precisely determined, and operation of searching the security domain involved to the firewall policy by artificiallychecking the network topology structure is unnecessary, therefore, the management efficiency of the firewall policy is improved, and the error rate of the configuration of the firewall policy is reduced at the same time.
