DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Reference is now made to Figs. 1A, IB, 1C, ID and IE, which are simplified pictorial illustrations of operation of the data access permission management system of an embodiment of the present invention for revoking and thereafter regranting pre-existing access permissions of a user to network objects at future times set in advance by an operator.

As seen generally in Figs. 1A - IE, the network object access permission management system is useful with a computer network 100 including at least one server 102 and a multiplicity of clients 104. One or more storage elements 106 are also preferably provided. The system preferably resides on the server 102 and preferably includes:

an access permissions subsystem 110 which governs access permissions of users to network objects in the computer network 100 in real time; and

a future condition-based permissions instruction subsystem 112 providing instructions to the access permission subsystem 110 to grant or revoke access permissions of the users to network objects in real time in response to future fulfillment of conditions which are established by an operator in advance.

The term "network object" for the purposes of this application is defined to include user generated enterprise computer network resources on any commercially available computer operating system. Examples of network objects include structured and unstructured computer data resources such as files and folders, and user groups.

Access permissions of users to network objects may include for example, read or write permissions to a file, modification permissions to a folder (e.g. permissions to create or delete files), and modification permissions to a user group (e.g. permissions to add or remove a user from the group).

Fig. 1A shows a stage in typical operation of the data access permission management system, wherein an IT manager employs the future condition-based permission instruction subsystem 112 for revoking all access permissions for an employee about to go on vacation. The IT manager sets a future start date and a duration for the revocation, after which duration, the access permissions will be automatically restored. Fig. IB shows that at 12:01AM on July 15, the future start date set by the IT manager, the future condition-based permission instruction subsystem 112 automatically provides instructions to the access permission subsystem to immediately revoke all access permissions to the employee.

As seen in Fig. 1C, for the duration of the employee's vacation, typically on July 21, access is denied to the employee.

Fig. ID illustrates that automatically upon expiration of the above duration, the future condition-based permission instruction subsystem automatically provides instructions to the access permission subsystem to immediately regrant all access permissions to the employee and Fig. IE illustrates that thereafter, the employee employs the restored access permissions.

Reference is now made to Figs. 2A, 2B, 2C, 2D, and 2E, which are simplified pictorial illustrations of operation of the data access permission management system of an embodiment of the present invention for revoking and thereafter regranting pre-existing access permissions of a user to network objects in response to a future event set in advance by an operator.

As seen generally in Figs. 2A - 2E, the network object access permission management system is useful with a computer network 200 including at least one server 202 and a multiplicity of clients 204. One or more storage elements 206 are also preferably provided. The system preferably resides on the server 202 and preferably includes:

an access permissions subsystem 210 which governs access permissions of users to network objects in the computer network 200 in real time; and

a future condition-based permissions instruction subsystem 212 providing instructions to the access permission subsystem 210 to grant or revoke access permissions of the users to network objects in real time in response to future fulfillment of conditions which are established by an operator in advance.

Fig. 2A shows a stage in typical operation of the data access permission management system, wherein an IT manager employs the future condition-based permission instruction subsystem 212 for revoking all access permissions for an employee who is about to give birth and go on maternity leave. The IT manager sets a condition for revoking access permissions, i.e. maternity leave, after which duration, the access permissions will be automatically restored.

Fig. 2B shows that at 12:01AM on July 15, the future condition-based permission instruction subsystem 212 routinely queries a human resources system 218 residing on a server 220 connected to the network 200, whether the employee has given birth and is now on maternity leave. Upon discovering that the employee is now indeed on maternity leave, the future condition-based permission instruction subsystem 212 orders the access permissions subsystem 210 to revoke all access permissions from the employee.

As seen in Fig. 2C, for the duration of the employee's maternity leave, typically on July 21, access is denied to the employee.

Fig. 2D illustrates that on July 29 the future condition-based permission instruction subsystem 212 routinely queries the human resources system 218 and discovers that the employee is no longer on maternity leave. The future condition-based permission instruction subsystem 212 immediately orders the access permissions subsystem 210 to regrant all access permissions to the employee, and Fig. 2E illustrates that thereafter, the employee employs the restored access permissions.

Reference is now made to Figs. 3A, 3B and 3C, which are simplified pictorial illustrations of operation of the data access permission management system of an embodiment of the present invention for changing access permissions of a user to network objects in response to a future event at a known date set in advance by an operator

As seen generally in Figs. 3A - 3C, the network object access permission management system is useful with a computer network 300 including at least one server 302 and a multiplicity of clients 304. One or more storage elements 306 are also preferably provided. The system preferably resides on the server 302 and preferably includes:

an access permissions subsystem 310 which governs access permissions of users to network objects in the computer network 300 in real time; and

a future condition-based permissions instruction subsystem 312 providing instructions to the access permission subsystem 310 to grant or revoke access permissions of the users to network objects in real time in response to future fulfillment of conditions which are established by an operator in advance.

Fig. 3A shows a stage in typical operation of the data access permission management system, wherein an IT manager employs the future condition-based permission instruction subsystem 312 for revoking all access permissions for an employee to certain enterprise resources and for granting access permissions for the employee to other enterprise resources, due to the employee transferring to another department in the enterprise. The IT manager sets a future start date for the simultaneous revocation and granting of access permissions.

Fig. 3B shows that at 12:01AM on July 15, the future start date set by the

IT manager, the future condition-based permission instruction subsystem 312 automatically provides instructions to the access permission subsystem 310 to immediately revoke all existing access permissions to the employee, and to grant new, alternative, access permissions to the employee.

As seen in Fig. 3C, after transferring to another department in the enterprise, typically on July 21, access to resources belonging to the previous department is denied to the employee, while access to resources belonging to the employee's new department is granted.

Reference is now made to Figs. 4A, 4B and 4C, which are simplified pictorial illustrations of operation of the data access permission management system of an embodiment of the present invention for changing access permissions of a user to network objects in response to a future event associated with a related user at a known date set in advance by an operator.

As seen generally in Figs. 4A - 4C, the network object access permission management system is useful with a computer network 400 including at least one server 402 and a multiplicity of clients 404. One or more storage elements 406 are also preferably provided. The system preferably resides on the server 402 and preferably includes:

an access permissions subsystem 410 which governs access permissions of users to network objects in the computer network 400 in real time; and

a future condition-based permissions instruction subsystem 412 providing instructions to the access permission subsystem 410 to grant or revoke access permissions of the users to network objects in real time in response to future fulfillment of conditions which are established by an operator in advance.

Fig. 4A shows a stage in typical operation of the data access permission management system, wherein an IT manager employs the future condition-based permission instruction subsystem 412 for revoking all access permissions for an employee to certain enterprise resources and for granting access permissions for the employee to other enterprise resources, due to the employee transferring to another department in the enterprise as a result of the employee's manager transferring to another department in the enterprise. The IT manager sets a future start date for the simultaneous revocation and granting of access permissions.

Fig. 4B shows that at 12:01AM on July 15, the future start date set by the IT manager, the future condition-based permission instruction subsystem 412 automatically provides instructions to the access permission subsystem 410 to immediately revoke all existing access permissions to the employee, and to grant new, alternative, access permissions to the employee.

As seen in Fig. 4C, after transferring to another department in the enterprise, typically on July 21, access to resources belonging to the previous department is denied to the employee, while access to resources belonging to the employee's new department is granted.

Reference is now made to Fig. 5, which is a simplified flowchart indicating steps in the operation of the data access- permission management system of Fig. 1. As shown in Fig. 5, an IT manager utilizes the system by entering to the system an access permissions modification instruction to be implemented by the system upon fulfillment of a future condition. For example, the future condition may comprise the occurrence of a future date or an employee related event such as leave of absence of an employee, maternity leave, vacation leave, termination of employment of an employee and transfer of an employee to another department in the enterprise. The access permissions modification instruction may comprise granting or revoking access permissions of users to network objects.

The system continuously monitors relevant resources on the computer enterprise network for the fulfillment of the future condition. The resources may include, for example, human resources databases and IT security-related systems. Upon discovery that the future condition has been fulfilled, the system implements the access permissions modification instruction, and removes the access permissions modification instruction and its related future condition from the system.

Reference is now made to Fig. 6, which is another simplified flowchart indicating steps in the operation of the data access permission management system of Fig. 1. As shown in Fig. 6, an IT manager utilizes the system by entering to the system a temporary access permissions modification instruction to be implemented by the system for the duration of a future state. For example, the future state may comprise the occurrence of a future date or range of dates, or an employee related state such as leave of absence of an employee, maternity leave, vacation leave and temporary transfer of an employee to another department in the enterprise. The temporary access permissions modification instruction may comprise temporarily granting or revoking access permissions of users to network objects.

The system continuously monitors relevant resources on the computer enterprise network for the existence of the state. The resources may include, for example, human resources databases and IT security-related systems.

Upon discovering the existence of the state, the system implements the temporary access permissions modification instruction. The system continues to monitor relevant resources on the computer enterprise network for the continued existence of the state.

Upon discovering that the state no longer exists, the system reverses the temporary access permissions modification instruction, and removes the temporary access permissions modification instruction and its related future state from the system.

It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. Rather the scope of the present invention includes both combinations and subcombinations of the various features described hereinabove as well as modifications thereof which would occur to persons skilled in the art upon reading the foregoing description and which are not in the prior art.
