Eliminating network security blind spots

Abstract

Blind spots in a network system are identified and eliminated. Synthetic transactions are generated and transmitted across a network system, and at least a portion of the synthetic transactions is captured. Parts of the synthetic transactions that were not captured can be determined and employed to generate a logical security map of the network system based on the captured synthetic transactions. At least one blind spot can be identified from in the logical security map of the network system, and a solution determined to eliminate the at least one blind spot. Subsequently, the solution is implemented for the network system to eliminate the blind spot.

Description

BACKGROUND

Network security is increasingly important. Security assets are deployed on network systems to ensure malicious software, data packets, or traffic are detected for the network system before causing network interruptions or compromising important data. However, oftentimes, the security assets fail to protect the entirety of the network system. The security assets may not protect unpredictable blind spots in the network system that can lead to the susceptibilities in the network system that can be compromised. Further, it is difficult and dangerous to troubleshoot and detect blind spots through conventional real network traffic.

BRIEF SUMMARY OF THE DESCRIPTION

The following presents a simplified summary of aspects of this disclosure to provide a basic understanding of some aspects of the innovation. This summary is not an extensive overview of the innovation. It is not intended to identify key/critical elements of the innovation or to delineate the scope of innovation. Its sole purpose is to present some concepts of the innovation in a simplified form as a prelude to the more detailed description that is presented later.

The innovation, as disclosed and claimed herein, in one aspect thereof, comprises systems and methods for eliminating network security blind spots. In one instance, a system is disclosed that comprises a hardware processor coupled to a memory that stores instructions that, when executed by the processor to generate a synthetic transaction that replicates an expected transaction on a network system for testing, initiate transmission of the synthetic transaction across the network system, and determine a blind spot in the network system where the synthetic transaction was sent and undetected. In one instance, the synthetic transaction can be designed so that it cannot damage the network system. The instructions further cause the processor to generate a logical security map of the network system based on captured synthetic transactions. The processor can subsequently identify the synthetic transaction as undetected based on analysis of the logical security map of the network system such that a synthetic transaction is deemed undetected when it is not captured by the logical security map. The analysis can also compare an expected logical security map to the logical security map to determine if the synthetic transaction is undetected. The instructions can further cause the processor to determine a solution to eliminate the blind spot. In one instance, the processor can initiate reconfiguration of a security asset to eliminate the blind spot. In another instance, the processor can initiate acquisition of a security asset to eliminate the blind spot. Further, the instructions can cause the processor to identify the blind spot on a heat map.

A method is also disclosed that comprises generating a synthetic transaction that replicates an expected transaction on a network system for testing, initiating transmission of the synthetic transaction across the network system, and determining a blind spot in the network system where the synthetic transaction was sent and undetected. The method further comprises identifying the synthetic transaction as undetected based on analysis of a logical security map of the network system. The method includes comparing an expected logical security map to the logical security map to identify an undetected transaction in one scenario. The method further comprising identifying an undetected synthetic transaction when the synthetic transaction is present in the expected logical security map and absent from the logical security map. The method further comprises identifying a solution that eliminates the blind spot by initiating configuration of a security asset to eliminate the blind spot or initiating acquisition of a security asset that eliminates the blind spot.

Also disclosed is a computer-readable storage medium having instructions stored thereon that enable at least one processor to perform operations upon execution of the instructions. The operations comprise generating a synthetic transaction that replicates an expected transaction on a network system for testing, wherein the synthetic transaction is unable to harm the network system, initiating transmission of the synthetic transaction across the network system, and determining a blind spot in the network system where the synthetic transaction was sent and undetected. Further, the operations can comprise deeming the synthetic transaction undetected based on analysis of a logical security map of the network system. Further, the operations comprise identifying a solution that eliminates the blind spot.

In aspects, the subject innovation provides substantial benefits in terms of network diagnostics and security. One advantage resides in a better understanding of the deficiencies of network security assets.

FIG. 1 illustrates a system 100 for determining network system blind spots in security assets/protocols implemented on a network system. The system 100 includes a traffic generator 110. The traffic generator 110 can generate synthetic transactions to test the network system. In some embodiments, the synthetic transactions travel across the network system. In some embodiments, the synthetic transactions replicate usual traffic expected for the network system. The synthetic transactions are known by a technician and are designed such that the synthetic transactions cannot damage the network system. The traffic generator 110 can replicate network traffic between nodes on the network system. The traffic generator 110 can generate traffic that can appear to be from outside the network system to specific nodes or parts of the network system.

The network system can be a mobile network, wired LAN, wireless LAN, an internet network, or the like to transmit communications. The network system can be a corporation-wide network that provides online services and/or access to corporate sites and/or information. In some embodiments, the network system is made up of network segments. The network system can be divided into a series of smaller networks (e.g., sub-networks, virtual networks, ad hoc networks, and/or the like) that can provide access to different services, devices, and/or functionality. The network system can control access to various network segments such that only part of the network may be available to certain users, devices, and/or applications.

The system 100 includes a capture component 120. The capture component 120 can capture the generated synthetic transactions at various locations of the network system. The capture component 120 resides on the network system. The capture component 120 can detect the synthetic transactions on the network system. In some embodiments, the capture component 120 is made of security assets residing on the network system. The security assets are hardware or software implementations to detect malicious network traffic. The capture component 120 can use the security assets to detect the synthetic transactions at different parts or nodes on the network system. In some embodiments, the capture component 120 captures part of the synthetic transactions and does not capture other synthetic transactions.

The system 100 includes a map component 130. The map component 130 generates a logical security map of the network system based on the captured synthetic transactions from the capture component 120. The map component 130 determines parts of the network where the synthetic transactions were detected and parts of the network where the synthetic transactions were not detected. The map component 130 can indicate blind spots in the network system where synthetic transactions were not detected where the transactions were sent and therefore expected to be detected.

The system 100 includes an implementation component 140. The implementation component 140 determines a solution to eliminate blind spots in the network system and implements the solution for the network system. In some embodiments, the implementation component 140 can prioritize acquisition of security assets to eliminate a blind spot. In other embodiments, the implementation component 140 can restructure and/or reconfigure existing security assets of the network system to eliminate a blind spot.

FIG. 2 illustrates a detailed component diagram of the traffic generator 110. The traffic generator 110 includes a packet configurator 210. The packet configurator 210 generates data packets between a plurality of nodes residing on the network system that mimic a financial transaction. The packet configurator 210 can design the data packets with benign data. In some embodiments, the data packets include a source address field and a destination address field that are recorded or otherwise known to the network system. The packet configurator 210 can generate a packet to be sent to each node in the network system such that the entire network system may be tested by the capture component 120 and mapped by the map component 130.

The traffic generator 110 includes a networking component 220. The networking component 220 sends the synthetic transactions and/or the data packets through the network system to simulate conventional traffic on the network system. In some embodiments, the networking component 220 can access or reside on a corporation-wide network that provides online services and/or access to corporate sites and/or information.

FIG. 3 illustrates a component diagram of the map component 130. The map component 130 includes a determination component 310 that determines the synthetic transactions that were not captured. In some embodiments, the determination component 310 can receive the total synthetic transactions sent through the network system from the traffic generator 110. The determination component 310 can receive the captured synthetic transactions from the capture component 120. The determination component 310 evaluates the differences between the total synthetic transactions and the captured transactions. The map component 130 generates a logical security map based on the evaluated differences.

In another embodiment, the map component 130 includes a prediction component 320 that generates an expected security map of the network system. The expected security map can be determined by an evaluation of the security assets to determine expected captured synthetic transactions or traffic. A comparison component 330 compares the expected security map to the generated logical security map to determine blind spots. For example, synthetic transactions directed to Node A of the network system were expected to be captured based on the expected security map. However, it was observed by the capture component 120 that the synthetic transactions were not detected, and therefore the logical security map shows there were no captured synthetic transactions. The comparison component 330 compares the expected security map to the logical security map and determines where expected captures are missing as blind spots.

In some embodiments, the map component 130 may include a heat map component 340 that generates a heat map of the network system based on the captured synthetic transactions. The heat map component 340 can generate a heat map that graphically depicts the severity of blind spots. For example, a node in which a lot of the synthetic transactions passed through uncaptured can be depicted in the heat map as a highlighted or more intensely hued color. In contrast, generally safe nodes where all transactions were captured can be depicted in a more muted color. The heat map provides the system 100, the implementation component 140, and/or a technician with visual feedback to facilitate prioritizing elimination of more critical blind spots over less critical blind spots.

FIG. 4 illustrates a component diagram of the implementation component 140. The implementation component 140 determines a solution to eliminate the at least one blind spot. The implementation includes a priority component 410. The priority component 410 prioritizes acquisition of at least one security asset to be deployed onto the network system that eliminates the at least one blind spot. In some embodiments, the priority component 410 determines a recommendation to a technician for acquiring additional security assets.

The implementation component 140 can include a restructuring component 420. The restructuring component 420 reconfigures existing security assets that are deployed on the network system. For example, the restructuring component 420 can determine a redundancy of security assets at one part of the network and recommend a redundant security asset to be deployed to a part of the network system having a blind spot. In some embodiments, the restructuring component 420 can determine a new configuration of an existing security asset to eliminate a blind spot. For example, a security asset that is not receiving many synthetic transactions or network traffic may be expanded in scope to include parts of the network system having a blind spot.

With reference to FIG. 5, example methods 500 are depicted for authenticating a user to verify identity. While, for purposes of simplicity of explanation, the one or more methodologies shown herein, e.g., in the form of a flow chart, are shown and described as a series of acts, it is to be understood and appreciated that the subject innovation is not limited by the order of acts, as some acts may, in accordance with the innovation, occur in a different order and/or concurrently with other acts from that shown and described herein.

FIG. 5 illustrates a method 500 for determining network system blind spots in security assets/protocols implemented on a network system. At 510, synthetic transactions are generated across a network system. For example, a network system is to be tested for blind spots. Synthetic transactions are generated to be directed across the entire (or substantially the entire) network system for a complete test for blind spots.

At 520, the generated synthetic transactions are captured at the network system level. The synthetic transactions may be captured using hardware security assets, software security tools, and/or a combination of the two. At 530, synthetic transactions that were not captured on the network system are determined. At 540, a logical security map of the network system based on the captured and not captured synthetic transactions is generated. The logical security map can show where the synthetic transactions were and were not captured.

At 550, blind spots in the logical security map of the network system are determined. The blind spots are parts in the network system where synthetic transactions were sent but were not detected during the capture 520. At 560, solutions to eliminate the blind spots in the network system are determined. The solutions can be acquisition of security assets to fill the blind spots or restructuring or reconfiguring of existing security assets.
