1. An image processing apparatus comprising at least one processor and at least one memory coupled to the at least one processor which acts as:
a management unit configured to manage write authority information of one of communities defined in Simple Network Management Protocol (SNMP) indicating an authority to change a setting value of a setting item in Management Information Base (MIB);
a security policy setting unit configured to set whether or not to apply a security policy regarding a setting value in the MIB information an application operated in the image forming apparatus wherein the security policy provides a setting constraint for the setting value in the MIB information and wherein the security policy regarding the setting value in the MIB information is defined separately from the communities defined in SNMP;
a receiving unit configured to receive a SNMP set request from an information processing apparatus capable of communicating with the image processing apparatus via a network, the SNMP set request including community information and setting item information for identifying a setting item;
a determination unit configured to, based on the community information included in the SNMP set request received by the receiving unit, the setting item information included in the SNMP set request, and the write authority information regarding the community defined in SNMP managed by the management unit, determine whether a community corresponding to the community information included in the SNMP set request has a write authority on the setting item identified by the setting item information included in the SNMP set request; and
a control unit configured to, in at least a condition that the determination unit determines that the community has the write authority on the identified setting item and the security policy setting unit sets to apply the security policy which provides a setting constraint regarding a setting value of a setting item regarding the MIB information control whether to permit a change of a setting value of the identified setting item, based on a setting value of security policy associated with the identified setting item after the determination by the determination unit, and
at least in a condition that the determination unit determines that the community has the write authority on the identified setting item in the MIB information and the security policy setting unit does not set to apply the security policy which provides the setting constraint regarding the setting value, control whether to permit a change of a setting value of the identified setting item in accordance with the authority information in association with the communities defined in SNMP without the security policy.
