2. Description of the Related Art
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes, thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more information handling systems, data storage systems, and networking systems.
It is known to install software and to perform tests on information handling systems before they are shipped to businesses or individual customers. A goal of software installation is to efficiently produce a useful, reliable information handling system. Software installation often includes loading a desired package of software onto the information handling system, preparing appropriate environment variables for the information handling system, and preparing appropriate initialization files for the loaded software.
When installing hardware and software onto multiple information handling systems in a manufacturing environment, one issue relates to installing firewall software onto the multiple information handling systems.
Known firewall software includes application level checks whenever an application requests access to the internet. Many known firewall implementations allow a user to grant or block access to the internet by a given application. For security reasons, simply adding file names to a default approved application list is generally not permitted by the firewall software. Some form of additional authentication is performed to assure that the application has not been modified from its original form. One form that this additional authentication has taken is generating a unique application identifier, such as a checksum, that uniquely identifies a particular application. For example, known firewall applications use an MD5 signature as a checksum which is used by the firewall application to determine whether an application in the firewall application database has changed.
One challenge associated with pre-installing firewall software is that even when the firewall is configured to allow certain applications access, an application that is installed may be a different version from that identified by the firewall software provider checksum and therefore the checksum may not match what had been previously allowed. This challenge is further enhanced when an information handling system manufacturer develops its own software applications (e.g., support applications, alert applications and solution center applications) that firewall software providers do not necessarily have visibility to and cannot maintain an updated database of checksums without a great deal of manual effort.
It is desirable to address challenges associated with factory installing a firewall application in a dynamic build to order environment. For example, customers may not appreciate why they are prompted when an application requests access to the internet, so they may block the application request and thus deny their system access to the internet. Additionally, customers may block access to the internet of manufacturer specific applications that actually increase the security of the system such as support applications and alert applications.
In accordance with the present invention, a system which dynamically generates a list of applications on an individual machine that a firewall application should enable access to the internet by default is provided. The system includes an assumption that applications installed during the factory install process are safe and have not had a chance to be modified by a Trojan since the machine has not yet been connected to the internet. The list is generated via registering applications during factory installation and expecting firewall application providers to scan this list of registered applications during the installation or setup of the firewall application and to add all applications in the list to the list of default trusted applications.
Such a system advantageously provides a seamless customer experience when operating an information handling system with preinstalled firewall software. Such a system also advantageously provides a customer with access to the firewall application without having to make decisions that are unnecessary for the security of the system.
One embodiment of the invention relates to a method for pre-trusting applications for a firewall application. The method includes reading an order for an information handling system, installing a software application onto the information handling system, adding an identifier for the software application to a list of trusted applications, installing the firewall application onto the information handling system, and accessing the list of trusted applications to automatically identify to the firewall application that the software application is a trusted application.
In another embodiment, the invention relates to an apparatus for pre-trusting applications for a firewall application. The apparatus includes means for reading an order for an information handling system, means for installing a software application onto the information handling system, means for adding an identifier for the software application to a list of trusted applications, means for installing the firewall application onto the information handling system, and means for accessing the list of trusted applications to automatically identify to the firewall application that the software application is a trusted application.
In yet another embodiment, the invention relates to an information handling system which includes a processor, memory coupled to the processor, a firewall application stored on the memory, and an approved application file stored on the memory. The approved application file includes a list of trusted applications. The firewall application accesses the list of trusted applications to automatically identify a software application as a trusted software application.
The present invention may be better understood, and its numerous objects, features and advantages made apparent to those skilled in the art by referencing the accompanying drawings. The use of the same reference number throughout the several figures designates a like or similar element.
Because different families of information handling systems and different individual computer components may require different software installations, it is desirable to determine which software to install on a target information handling system 120. A descriptor file 130 is provided by converting an order 110, which corresponds to a desired information handling system having desired components, into a computer readable format via conversion module 132.
Component descriptors are computer readable descriptions of the components of target information handling system 120 which components are defined by the order 110. In one embodiment, the component descriptors are included in a descriptor file called a system descriptor record which is a computer readable file containing a listing of the components, both hardware and software, to be installed onto target information handling system 120. Having read the plurality of component descriptors, database server 140 provides an image having a plurality of software components corresponding to the component descriptors to file server 142 over network connection 144. Network connections 144 may be any network connection well-known in the art, such as a local area network, an intranet, or the internet. The information contained in database server 140 is often updated such that the database contains a new factory build environment. The software is then installed on the target information handling system 120 via file server 142. The software is installed on the target information handling system via the image. The image may include self-configuring code.
The database server 140 may also be provided with an approved application firewall file 180. The approved application firewall file 180 identifies to the installed firewall software a list of those applications that are installed during the manufacture of the target system 120 and are thus presumed safe from the standpoint of the firewall software.
An approved application system 182 dynamically generates the approved application firewall file 180 based upon applications that are to be installed on an individual target system 120. The applications that are to be installed may be derived from the descriptor file 130. Thus, the approved application firewall file 180 sets forth applications that a firewall application should enable access to the internet by default. The system 182 includes the assumption that applications installed during the factory install process are safe and have not had a chance to be modified by a Trojan since the machine has not yet been connected to the internet.
