SECURITY SETTING SUPPORT APPARATUS, SECURITY SETTING SUPPORT METHOD AND PROGRAM

1 . A security setting support device for supporting security setting for a device on a network, the security setting support device comprising:

a preliminary verification unit, including one or more processors, configured to perform preliminary verification for determining whether a security setting parameter is settable for the device based on a verification scenario including a feature amount obtained from traffic data in the network and the security setting parameter; and

a verification result output unit, including one or more processors, configured to output a result of the preliminary verification.

2 . The security setting support device according to claim 1 , further comprising

a setting control unit, including one or more processors, configured to set, for the device, a security setting parameter determined to be settable by the preliminary verification unit.

3 . The security setting support device according to claim 1 , wherein

the preliminary verification unit is configured to make the determination by performing preliminary verification simulation by use of a learned model learned by supervised machine learning.

4 . The security setting support device according to claim 1 , wherein

in a case where it is determined that the security setting parameter is not settable for the device, the preliminary verification unit is configured to change the security setting parameter and make the determination again by use of the changed security setting parameter.

5 . The security setting support device according to claim 1 , wherein

the security setting parameter is a threshold value for detecting a DDoS attack on the network.

6 . The security setting support device according to claim 5 , wherein

the preliminary verification unit is configured to make the determination based on whether a DDoS attack is not overlooked by the threshold value, whether a normal communication is not erroneously detected as a DDoS attack by the threshold value, or whether an SLA of a service is satisfied by the threshold value.

7 . A security setting support method executed by a security setting support device that supports security setting for a device on a network, the security setting support method comprising:

a preliminary verification step of performing preliminary verification for determining whether a security setting parameter is settable for the device based on a verification scenario including a feature amount obtained from traffic data in the network and the security setting parameter; and

a verification result output step of outputting a result of the preliminary verification.

8 . A non-transitory computer-readable storage medium storing a program for causing a computer to function as a security setting support device for supporting security setting for a device on a network to perform operations comprising:

performing preliminary verification for determining whether a security setting parameter is settable for the device based on a verification scenario including a feature amount obtained from traffic data in the network and the security setting parameter; and

outputting a result of the preliminary verification.

9 . The non-transitory computer-readable storage medium according to claim 8 , wherein the operations further comprise:

setting, for the device, a security setting parameter determined to be settable by the preliminary verification unit.

10 . The non-transitory computer-readable storage medium according to claim 8 , wherein the operations further comprise:

making the determination by performing preliminary verification simulation by use of a learned model learned by supervised machine learning.

11 . The non-transitory computer-readable storage medium according to claim 8 , wherein the operations further comprise:

in a case where it is determined that the security setting parameter is not settable for the device, changing the security setting parameter and makes the determination again by use of the changed security setting parameter.

12 . The non-transitory computer-readable storage medium according to claim 8 , wherein

the security setting parameter is a threshold value for detecting a DDoS attack on the network.

13 . The non-transitory computer-readable storage medium according to claim 12 , wherein the operations further comprise:

making the determination based on whether a DDoS attack is not overlooked by the threshold value, whether a normal communication is not erroneously detected as a DDoS attack by the threshold value, or whether an SLA of a service is satisfied by the threshold value.

14 . The security setting support method according to claim 7 , further comprising:

setting, for the device, a security setting parameter determined to be settable by the preliminary verification unit.

15 . The security setting support method according to claim 7 , further comprising:

making the determination by performing preliminary verification simulation by use of a learned model learned by supervised machine learning.

16 . The security setting support method according to claim 7 , further comprising:

in a case where it is determined that the security setting parameter is not settable for the device, changing the security setting parameter and makes the determination again by use of the changed security setting parameter.

17 . The security setting support method according to claim 7 , wherein

the security setting parameter is a threshold value for detecting a DDoS attack on the network.

18 . The security setting support method according to claim 17 , further comprising:

making the determination based on whether a DDoS attack is not overlooked by the threshold value, whether a normal communication is not erroneously detected as a DDoS attack by the threshold value, or whether an SLA of a service is satisfied by the threshold value.
