This invention relates to the field of cloud computing and more particularly to a system for expedited delivery of files from cloud systems.
The use of cloud computing has become ubiquitous. Cloud storage is used to safely store backup files, corporate databases, user files such as photographs, or just about anything that was previously stored locally to a home or office computer, previously in local mass storage.
Currently, many software systems attempt to provide a secure computing environment to a large variety of systems and devices such as computers, smartphones, notepads, smartwatches, etc. Protection software is typically loaded on these systems and devices that recognizes viruses and thwarts attempts at loading, storing, or executing of viruses or other malware. As virus and malware evolves, the protection software must evolve as well to be aware of new virus strains and new forms of malware. As new viruses and malware are found, entries or scripts are added to files used by the protection software in the detection and prevention of viruses and malware. In the past, the protection software evolved by periodically accessing a central server to see if new protection files are available, downloading the new protection file when they are available. As most devices are now connected to a network and have access to the Internet, the protection files are often stored in cloud storage to enable concurrent distribution to a large number of devices. As such, when administrators make a change to one of the protection files stored in cloud storage, eventually all devices will have access to the updated protection files, but not instantaneously.
As an example of the above, some protection software limits execution of programs to those on a list of allowed programs. When a user requests that an administrator allow execution of a new program, the administrator adds that program to the protection files, then while in communications with the user, the administrator often wishes to make sure the change to the protection files works as expected and the user is able to run the program, but due to various activities with cloud computing, it often takes several minutes before the protection file is distributed to all protected systems. This results in longer than needed interactions between the user and administrator as the communications between them need be open until the new protection file appears on the user’s device and, as this often takes several minutes, the user must periodically check to see if the program can be run.
What is needed is a system that will cause the protection software to pull down the protection file in real-time.
Distribution of files/settings such as virus protection files is a difficult task. For example, security software such as antimalware software periodically checks to see if new virus protection files are available. In the past, such checking was performed on a daily or weekly basis or on-demand when users are notified of an important update. Now with modern, high-speed data communications to protected devices, checking is performed more regularly, perhaps every ten minutes. Although ten minutes does not seem like a long time, when an end-user desires to run an application that is not currently in a whitelist and the administrator has added that application to the master whitelist, the end-user will have to wait up to ten minutes to see the change and the administrator often needs to continue communications with the end-user during that time to make sure the change to the whitelist did what was expected. Further, when a particularly dangerous malware is uncovered, every minute that this malware has the opportunity to infect user devices adds to the risk of such infection. Still further, it is often desired to update files such as whitelists and blacklist concurrently across a population of user devices, for example, all user devices in a company, or all user devices in a department.
As cloud computing becomes more prevalent, especially for use in distributing certain security software updates, the time gap between a change to a security software update in the cloud (e.g., a master file, settings) and delivery of the security software update to many user devices is of issue. For one, this time lag creates frustration between the end users and the administrators, as changes to permissions are not immediately available at the devices of the user. Further, although a short interval, when critical updates are made to the security software, the time between the updates to the cloud and distribution to all devices leaves a window of opportunity for attacks by malware.
In one embodiment, a system for computer security is disclosed including security software running on a user device. The security software has a local file or settings for control of the security software (e.g., whitelists, blacklists, virus detection files). A server has storage containing a master file for control of the security software. Upon initialization of the security software, the security software connects to the server by way of a persistent connection. After receipt of a refresh message over the persistent connection, the security software downloading the master file and updating the local file or settings from the master file.
In another embodiment, a method of protecting a user device, that has a processor is disclosed including installing security software on the user device. The security software runs on the processor after the user device is initialized and reads a local data file or settings to control access of the user device to resources (e.g., programs, network resources). Upon initialization of the security software on the processor, the security software makes a persistent connection to a server. When receiving a refresh message over the persistent connection, the security software downloads a master data file and updates the local data file and/or settings from the master data file.
In another embodiment, computer readable instructions for providing security to a user device are tangibly embodied in a non-transitory storage medium are disclosed including computer readable instructions running on a processor of the user device after the user device is initialized, the computer readable instructions reading a local data file to control access of the user device to resources. Upon initialization, the computer readable instructions running on the processor creates a persistent connection to a server and when the computer readable instructions running on the processor receives a refresh message over the persistent connection, the computer readable instructions running on the processor downloads a master data file and updates the local data file and/or settings from the master data file.
The invention can be best understood by those having ordinary skill in the art by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:
Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.
In general, the system for expedited delivery initiates fast downloads of cloud files that have been recently updated, in particular, virus protection files.
Throughout this description, the term, “computer” refers to any system that has a processor and runs software. One example of such is a personal computer. Another example is a smartphone or tablet. The term, “user” refers to a human that has an interest in the computer, perhaps a user who is using the computer.
In general, the user of the system, method, and apparatus being described utilizes cloud systems for distribution of virus prevention files and data such as whitelist, blacklists, virus scanner settings, and virus detection files.

As it is known in the industry, at some indeterminate time in the future, the copy of the master file 110C is downloaded to the user devices 12 and stored locally as local files 110A. This indeterminate time is dependent upon the cloud software system scheduling the downloads or the period of time that the file is requested by a program running on each user device 12, for example, by the security software 16 running on the user device 12. For example, some security software 16 requests updated files every ten minutes.
Once downloaded, the security software 16 accesses the local file 110A during, for example, virus scanning or determining if a program is allowed to run. Prior to the present disclosure, this indeterminate time ranges from seconds to several minutes, all of which time any changes to the master file 110M are not yet available at the user devices 12 as the master file 110M is not immediately downloaded to update the local files 110A.
To reduce this indeterminate time, the server 500 has a persistent communication link 14 to each security software 16 (the security software 16 runs on every user device 12 that is protected). When the master file 110M is updated, for example, when an administrator using the administrator device 10 adds an entry to the master file 110M, e.g., a new program to a whitelist, a message is sent out in one or more of the persistent communication links 14 and upon recognizing the message, the security software 16 that is running on each user device 12 initiates downloading of the master file 110M to update the local file 110A. Once the local file 110A is downloaded, the change is recognized by the security software 16, for example, the entry that was added to the master file 110M is now reflected in the local file 110A and, the new program is now permitted to run on the user device(s) 12.
In some embodiments, the persistent communication links 14 are named-pipes and a specific message such as “Blackwhiterefresh” is sent to clearly identify the task that the security software 16 need perform, e.g., update the local file 110A (e.g., whitelist/blacklist) from the master file 110M.

In the example of
If the incoming refresh message 206 is not received, a test to see if the timer expired 210 is made. If the timer expired 210, the download 208 is performed as above, for example retrieving a copy of the master file 110C from the cloud 100 or retrieving a copy of the master file 110M from the server 500. Once the download 208 is complete, the loop restarts with setting 204 the timer.
If the timer has not expired 210, then the above two tests are repeated.
The above is an exemplary implementation using a polling algorithm and it is equally anticipated to implement the same or similar functionality using interrupt algorithms in which the receipt of the refresh message and/or expiration of the timer interrupts the security software and initiates the download 208.
Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.
