Patent Application
20160092449
This disclosure relates in general to the field of information security, and more particularly, to data rating.
The field of network security has become increasingly important in today's society. The Internet has enabled interconnection of different computer networks all over the world. In particular, the Internet provides a medium for exchanging data between different users connected to different computer networks via various types of client devices. While the use of the Internet has transformed business and personal communications, it has also been used as a vehicle for malicious operators to gain unauthorized access to computers and computer networks and for intentional or inadvertent disclosure of sensitive information.
Malicious software (“malware”) that infects a host computer may be able to perform any number of malicious actions, such as stealing sensitive information from a business or individual associated with the host computer, propagating to other host computers, and/or assisting with distributed denial of service attacks, sending out spam or malicious emails from the host computer, etc. Hence, significant administrative challenges remain for protecting computers and computer networks from malicious and inadvertent exploitation by malicious software.
To provide a more complete understanding of the present disclosure and features and advantages thereof, reference is made to the following description, taken in conjunction with the accompanying figures, wherein like reference numerals represent like parts, in which:
The FIGURES of the drawings are not necessarily drawn to scale, as their dimensions can be varied considerably without departing from the scope of the present disclosure.
In example embodiments, communication system 10 can be configured to include a system where rating logic used for rating data in a data flow is separate from the rating system that uses the rating logic. Because it is separate from the rating system, the rating logic can be changed or added to without the need to patch or update the rating system. In addition, new rating types can be added to the rating logic by adding a new entry or variable to the rating logic.
Elements of
For purposes of illustrating certain example techniques of communication system 10, it is important to understand the communications that may be traversing the network environment. The following foundational information may be viewed as a basis from which the present disclosure may be properly explained.
Current security systems calculate/report on the (security) reputation of specific entities encountered on the Internet (e.g., URLs, files, IP addresses, email, etc.) using a rating system. The rating system typically involves a client (e.g., end user) sending a request for a rating of a particular rating type (e.g. URL) together with one or more data values to be used as a basis for the rating. The rating system uses some type of rating logic that interrogates one or more data sets for core reputation values and applies an algorithm or calculation to combine the values into a single rating of the type being requested. Traditionally, the data sets are local to the rating system and hard-coded within the rating system itself.
One problem with this approach is that there is typically one group or team responsible for the ratings and a different group that is responsible for the rating system. This can result in an inter-team dependency for any changes to the rating logic. The inter-team dependency can cause delays and potentially lengthy, high cost engineering cycles that have to be executed by each rating system team in order to modify existing rating logic. The potentially lengthy, high cost engineering cycles typically need to be executed by the group in charge of the rating system in order to deploy any rating logic for new rating types. Further, in the case where a rating system is running on premise, a product patching or updating cycle needs to be executed in order to deploy a change in the rating logic to all the end users. What is needed is a system that can update the rating logic without having to update the rating system.
A communication system for data rating, as outlined in
The rating logic is isolated from the rest of the rating system and can be deployed and updated using the same automatic update mechanisms as other data sets of the rating system. This allows the rating team to make changes to the rating logic in the same way they can change other content in the rating system and without the involvement of any other team. Also, the rating logic changes can be tested and deployed in isolation and independent of rating system engineering cycles. Further, new rating types can be added simply by adding a new entry to the rating logic table and independent of the rating system engineering cycles. In addition, rating logic changes and additions can be deployed both in the cloud and on-premise without any system or product patching or updating.
As a use example, to add a Twitter post (Tweet) rating feature based on the reputation of Twitter users and URLs referred to in a Tweet, a new dataset for “TwitterUserReputation” may be added as a new entry to the rating logic dataset with a key such as “Tweet” that would be associated with the appropriate logic to interrogate the URL and twitter user reputation datasets for each URL and user contained within the Tweet. The results could be combined into a single rating based on an appropriate algorithm. Such a system can avoid an engineering cycle and subsequent deployment of a new version of the rating system, which would be required to add in the new example feature.
Turning to the infrastructure of
In communication system 10, network traffic, which is inclusive of packets, frames, signals, data, etc., can be sent and received according to any suitable communication messaging protocols. Suitable communication messaging protocols can include a multi-layered scheme such as Open Systems Interconnection (OSI) model, or any derivations or variants thereof (e.g., Transmission Control Protocol/Internet Protocol (TCP/IP), user datagram protocol/IP (UDP/IP)). Additionally, radio signal communications over a cellular network may also be provided in communication system 10. Suitable interfaces and infrastructure may be provided to enable communication with the cellular network.
The term “packet” as used herein, refers to a unit of data that can be routed between a source node and a destination node on a packet switched network. A packet includes a source network address and a destination network address. These network addresses can be Internet Protocol (IP) addresses in a TCP/IP messaging protocol. The term “data” as used herein, refers to any type of binary, numeric, voice, video, textual, or script data, or any type of source or object code, or any other suitable information in any appropriate format that may be communicated from one point to another in electronic devices and/or networks. Additionally, messages, requests, responses, and queries are forms of network traffic, and therefore, may comprise packets, frames, signals, data, etc.
In an example implementation, electronic device 12, network gateway 14, cloud 16, and server 18 are network elements, which are meant to encompass network appliances, servers, routers, switches, gateways, bridges, load balancers, processors, modules, or any other suitable device, component, element, or object operable to exchange information in a network environment. Network elements may include any suitable hardware, software, components, modules, or objects that facilitate the operations thereof, as well as suitable interfaces for receiving, transmitting, and/or otherwise communicating data or information in a network environment. This may be inclusive of appropriate algorithms and communication protocols that allow for the effective exchange of data or information.
In regards to the internal structure associated with communication system 10, each of electronic device 12, network gateway 14, cloud 16, and server 18 can include memory elements for storing information to be used in the operations outlined herein. Each of electronic device 12, network gateway 14, cloud 16, and server 18 may keep information in any suitable memory element (e.g., random access memory (RAM), read-only memory (ROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), application specific integrated circuit (ASIC), etc.), software, hardware, firmware, or in any other suitable component, device, element, or object where appropriate and based on particular needs. Any of the memory items discussed herein should be construed as being encompassed within the broad term ‘memory element.’ Moreover, the information being used, tracked, sent, or received in communication system 10 could be provided in any database, register, queue, table, cache, control list, or other storage structure, all of which can be referenced at any suitable timeframe. Any such storage options may also be included within the broad term ‘memory element’ as used herein.
In certain example implementations, the functions outlined herein may be implemented by logic encoded in one or more tangible media (e.g., embedded logic provided in an ASIC, digital signal processor (DSP) instructions, software (potentially inclusive of object code and source code) to be executed by a processor, or other similar machine, etc.), which may be inclusive of non-transitory computer-readable media. In some of these instances, memory elements can store data used for the operations described herein. This includes the memory elements being able to store software, logic, code, or processor instructions that are executed to carry out the activities described herein.
In an example implementation, network elements of communication system 10, such as electronic device 12, network gateway 14, cloud 16, and server 18 may include software modules (e.g., rating module 20a, 20b, 20c, or 20d respectively) to achieve, or to foster, operations as outlined herein. These modules may be suitably combined in any appropriate manner, which may be based on particular configuration and/or provisioning needs. In example embodiments, such operations may be carried out by hardware, implemented externally to these elements, or included in some other network device to achieve the intended functionality. Furthermore, the modules can be implemented as software, hardware, firmware, or any suitable combination thereof. These elements may also include software (or reciprocating software) that can coordinate with other network elements in order to achieve the operations, as outlined herein.
Additionally, each of electronic device 12, network gateway 14, cloud 16, and server 18 may include a processor (e.g., processor 24a, 24b, 24c, and 24d respectively) that can execute software or an algorithm to perform activities as discussed herein.

Electronic device 12 can be a network element and includes, for example, desktop computers, laptop computers, mobile devices, personal digital assistants, smartphones, tablets, or other similar devices. Cloud 16 is configured to provide cloud services to electronic device 12. Cloud services may generally be defined as the use of computing resources that are delivered as a service over a network, such as the Internet. Typically, compute, storage, and network resources are offered in a cloud infrastructure, effectively shifting the workload from a local network to the cloud network. Server 18 can be a network element such as a server or virtual server and can be associated with clients, customers, endpoints, or end users wishing to initiate a communication in communication system 10 via some network (e.g., network 30). The term ‘server’ is inclusive of devices used to serve the requests of clients and/or perform some computational task on behalf of clients within communication system 10. Although rating module 20a is represented as being located in electronic device 12, rating module 20b is represented as being located in network gateway 14, rating module 20c is represented as being located in cloud 16, and rating module 20d is represented as being located in server 18, this is for illustrative purposes only. Each rating module 20a, 20b, 20c, and 20d could be combined or separated in any suitable configuration. Furthermore, each rating module 20a, 20b, 20c, and 20d could be integrated with or distributed in another network.
