- the monitoring program 11 can have a function of notifying an administrator when a specific keyword is found, and can quickly respond to a user's suspicious operation. it can.
- a warning can be displayed on the display 28 of the client computer 2 or the user of the client computer 2 can be notified by e-mail or the like. You can notify the administrator by displaying a warning on the administrator's computer, sending a warning to the administrator's mobile phone, or sending a warning to the administrator's email address.
- the database 13 and the screen image can be stored in another electronic computer on the power network stored in the monitoring server 3 or in a local or external recording device of the client computer 2.
- the screen image to be saved may be a black and white image in order to reduce the storage capacity.
- This database 13 is also accessed by the client computer 2, the monitoring server 3, and other electronic computers connected via the network to search the contents recorded there and to store screen images. Can be played.
- a monitoring tool 10 that operates on the client computer 2 and a monitoring program 11 that operates on the monitoring server 3 are provided.
- the manager program can have only a playback function of the stored screen image and a search function of the database 3.
- This manager program may be installed and operated on a computer that can access the screen image and database 3 saved by a dedicated application program.
- this manager program can be a web-based program.
- Screen image playback in kernel mode 32 When the screen image stored in the storage device 30 is played back by the monitoring server 3, a method of playing back in the user mode 31 or the kernel mode 32 is used.
- the flowchart in Fig. 8 shows how to replay a screen image in kernel mode 32.
- a request for screen image data is made to the driverware 22 (step 50).
- the driverware 22 receives this screen image reproduction request (step 51), and requests data from the storage device driver module 38 of the dryware 22 to the storage device driver 29 (step 52). .
- the storage device device driver 29 also acquires the requested data from the storage device 30 (step 53) and transmits it to the storage device driver module 38.
- the storage device driver module 38 passes the data received from the storage device device driver 29 to the driverware 22.
- the driverware 22 sends this data to the graphic device driver 24 via the GDI monitoring module 36 (steps 56 and 57).
- the graphic device driver 24 and the graphic card 25 create a screen image that can be displayed on the display 28 even when the data power received from the GDI monitoring module 36 is transmitted to the display 28 (steps 58 and 59).
- the stored screen image data force screen image is reproduced.
- the data obtained from the storage device 30 is transmitted and processed only through the kernel mode 32 of the operating system 21, so the operating system 21 needs to switch between the kernel mode 32 and the user mode 31. A series of processing is performed at high speed.
- a flowchart of FIG. 9 shows a method of reproducing a screen image in the user mode 31.
- the monitoring program 11 requests the storage device 30 for screen image data (screen playback data) (step 70). This request is sent to the storage device driver 29 via the subsystem 33 (step 71).
- the operating mode of the operating system 21 is changed from the user mode 31 to the kernel mode. Mode.
- the storage device device driver 29 receives this request (step 72), acquires the requested screen reproduction data from the storage device 30 (step 73), and passes it to the monitoring program 11 via the subsystem 29. (Steps 74, 75).
- the operation mode of the operating system 21 is switched from the kernel mode 32 to the user mode 31.
- the power driver used via the driverware 22 is used. Server 22 does not perform any processing on these data.
- the monitoring program 11 reproduces the screen image using the screen reproduction data via the GDI32 monitoring module 35 (step 76).
- the GDI32 monitoring module 35 passes the screen reproduction data for the screen image passed from the monitoring program 11 to GDI32 (34) and GDI32 (34) force GDI23 (steps 76 and 77).
- the operating mode of the operating system 21 is switched from the user mode 31 to the kernel mode 32.
- the GDI 23 passes the screen image data to the graphic device driver 24 (step 78).
- the graphic device driver 24 and the graphic card 25 create a screen image that can be displayed on the display 28 from the data card received from the GDI monitoring module 36 and transmit it to the display 28 (steps 79 and 80).
- the screen playback data power screen image stored in the storage device 30 is played back.
- data acquired from the storage device 30 is processed while switching between the kernel mode 32 and the user mode 31 of the operating system 21.
- the series of processing speeds is slower than when the screen image is played back only in kernel mode 32 (see the flowchart in Fig. 8).
- the monitoring system 1 can monitor the client computer 2 by storing a record of all operations until the user logs in the client computer 2 and logs off the power.
- the administrator can periodically check and monitor the usage status of the client computer 2 from the stored screen image and text data. For example, specify a specific time zone, search for saved screen images and text data, The usage status of the computer 2 can be monitored. In addition, the usage status of the client computer 2 can be confirmed randomly several times a day.
- the monitoring system 1 has a report function that periodically reports the usage status of the client computer 2.
- FIG. 10 shows an example of a report.
- a report 70 illustrated in FIG. 10 is a report when a user using the client computer 2 performs a suspicious operation.
- Report 70 shows reports 71-73 for three computers.
- Each report 71-73 contains “computer” indicating client computer 2, “user name” indicating the user of client computer 2, “login time” indicating the login time, and “logoff time” indicating the login time. ”, There is an item“ Number of suspicious operations ”indicating whether or not a suspicious operation has been performed.
