Abstract
The secondary OS is executed on the primary OS running on a computer, and a data server is implemented in the computer by executing an application program on the secondary OS. Then, executing an illegal access coping program on the primary OS, the computer accesses the data server, judges whether a response to the access received from the data server is normal or abnormal and obtains data stored in memory managed by the secondary OS if it is judged that the response is abnormal.
Claims20
A method for coping with an illegal access to a computer, comprising:
- executing a secondary operating system on a primary operating system running on the computer;
- executing an application program for implementing a data server publishing data in a communication network on the secondary operating system;
- accessing the data server, which is implemented by executing the application program, under the management of the primary operating system;
- judging whether a response to the access received from the data server is normal or abnormal, under the management of the primary operating system;
- and
- obtaining data stored in memory managed by the secondary operating system, under the management of the primary operating system if it is judged that the response is abnormal.
A method for coping with an illegal access to a computer, comprising:
- executing a secondary operating system on a primary operating system running on the computer;
- executing an application program for implementing a data server publishing data in a communication network on the secondary operating system;
- accessing the data server, which is implemented by executing the application program, through the communication network under the management of the primary operating system;
- judging whether a response to the access received from the data server through the communication network is normal or abnormal, under the management of the primary operating system;
- and
- compulsorily terminating the execution of the secondary operating system managing the execution of the application program, under the management of the primary operating system if it is judged that the response is abnormal.
A storage medium on which is recorded an illegal access coping program for enabling a computer to perform a process for coping with an illegal access to a data server publishing data in a communication network that is implemented in the computer by executing an application program on a secondary operating system executed on a primary operating system running on the computer, said illegal access coping program being executed on the primary operating system and enabling the computer to perform the following processes when being executed in the computer:
- accessing the data server implemented by executing the application program;
- judging whether a response to the access received from the data server is normal or abnormal;
- and
- obtaining data stored in memory managed by the secondary operating system if it is judged that the response is abnormal.
