This application claims the benefit of Greek Provisional Patent Application No. 20210100589, filed Sep. 8, 2021, which is hereby incorporated by reference in its entirety.
This technology generally relates to methods and systems for source code analysis, and more particularly to methods and systems for facilitating automatic analysis of source codes by using machine learning to identify secret information.
Many business entities utilize various software programs to provide services for consumers. Often, development of the software programs requires detailed source code analysis to ensure that secret and sensitive information are not inadvertently included in published products. Historically, implementation of conventional source code analysis techniques has resulted in varying degrees of success with respect to accurate and timely detection of the secret information.
One drawback of implementing conventional source code analysis techniques is that in many instances, the resulting data include many false positives. For example, a line of source code may be flagged as sensitive when there is no sensitive information present. As a result, developers must manually review positive detections, which requires large investments of time. Additionally, since secret information in a line of source code is traditionally flagged based on predetermined keywords, conventional source code analysis techniques are not able to anticipate and flexibly adjust to changing code environments.
Therefore, there is a need for an analysis technique that is based on machine learning to facilitate identification of secret information by efficiently and accurately analyzing large volumes of source codes.

The application(s) may be executed within or as virtual machine(s) or virtual server(s) that may be managed in a cloud-based computing environment. Also, the application(s), and even the SCPA device 202 itself, may be located in virtual server(s) running in a cloud-based computing environment rather than being tied to one or more specific physical network computing devices. Also, the application(s) may be running in one or more virtual machines (VMs) executing on the SCPA device 202. Additionally, in one or more embodiments of this technology, virtual machine(s) running on the SCPA device 202 may be managed or supervised by a hypervisor.
In the network environment 200 of
The communication network(s) 210 may be the same or similar to the network 122 as described with respect to
By way of example only, the communication network(s) 210 may include local area network(s) (LAN(s)) or wide area network(s) (WAN(s)), and can use TCP/IP over Ethernet and industry-standard protocols, although other types and/or numbers of protocols and/or communication networks may be used. The communication network(s) 210 in this example may employ any suitable interface mechanisms and network communication technologies including, for example, teletraffic in any suitable form (e.g., voice, modem, and the like), Public Switched Telephone Network (PSTNs), Ethernet-based Packet Data Networks (PDNs), combinations thereof, and the like.
The SCPA device 202 may be a standalone device or integrated with one or more other devices or apparatuses, such as one or more of the server devices 204(1)-204(n), for example. In one particular example, the SCPA device 202 may include or be hosted by one of the server devices 204(1)-204(n), and other arrangements are also possible. Moreover, one or more of the devices of the SCPA device 202 may be in a same or a different communication network including one or more public, private, or cloud networks, for example.
The plurality of server devices 204(1)-204(n) may be the same or similar to the computer system 102 or the computer device 120 as described with respect to
The server devices 204(1)-204(n) may be hardware or software or may represent a system with multiple servers in a pool, which may include internal or external networks. The server devices 204(1)-204(n) hosts the databases 206(1)-206(n) that are configured to store data that relates to data files, source code files, predetermined labels, training features, secret labels, non-secret labels, machine learning models, test files, set of source codes, features, and characteristics.
Although the server devices 204(1)-204(n) are illustrated as single devices, one or more actions of each of the server devices 204(1)-204(n) may be distributed across one or more distinct network computing devices that together comprise one or more of the server devices 204(1)-204(n). Moreover, the server devices 204(1)-204(n) are not limited to a particular configuration. Thus, the server devices 204(1)-204(n) may contain a plurality of network computing devices that operate using a master/slave approach, whereby one of the network computing devices of the server devices 204(1)-204(n) operates to manage and/or otherwise coordinate operations of the other network computing devices.
The server devices 204(1)-204(n) may operate as a plurality of network computing devices within a cluster architecture, a peer-to peer architecture, virtual machines, or within a cloud architecture, for example. Thus, the technology disclosed herein is not to be construed as being limited to a single environment and other configurations and architectures are also envisaged.
The plurality of client devices 208(1)-208(n) may also be the same or similar to the computer system 102 or the computer device 120 as described with respect to
The client devices 208(1)-208(n) may run interface applications, such as standard web browsers or standalone client applications, which may provide an interface to communicate with the SCPA device 202 via the communication network(s) 210 in order to communicate user requests and information. The client devices 208(1)-208(n) may further include, among other features, a display device, such as a display screen or touchscreen, and/or an input device, such as a keyboard, for example.
Although the exemplary network environment 200 with the SCPA device 202, the server devices 204(1)-204(n), the client devices 208(1)-208(n), and the communication network(s) 210 are described and illustrated herein, other types and/or numbers of systems, devices, components, and/or elements in other topologies may be used. It is to be understood that the systems of the examples described herein are for exemplary purposes, as many variations of the specific hardware and software used to implement the examples are possible, as will be appreciated by those skilled in the relevant art(s).
One or more of the devices depicted in the network environment 200, such as the SCPA device 202, the server devices 204(1)-204(n), or the client devices 208(1)-208(n), for example, may be configured to operate as virtual instances on the same physical machine. In other words, one or more of the SCPA device 202, the server devices 204(1)-204(n), or the client devices 208(1)-208(n) may operate on the same physical device rather than as separate devices communicating through communication network(s) 210. Additionally, there may be more or fewer SCPA devices 202, server devices 204(1)-204(n), or client devices 208(1)-208(n) than illustrated in
In addition, two or more computing systems or devices may be substituted for any one of the systems or devices in any example. Accordingly, principles and advantages of distributed processing, such as redundancy and replication, also may be implemented, as desired, to increase the robustness and performance of the devices and systems of the examples. The examples may also be implemented on computer system(s) that extend across any suitable network using any suitable interface mechanisms and traffic technologies, including by way of example only teletraffic in any suitable form (e.g., voice and modem), wireless traffic networks, cellular traffic networks, Packet Data Networks (PDNs), the Internet, intranets, and combinations thereof.
The SCPA device 202 is described and shown in
An exemplary process 300 for implementing a mechanism for facilitating automatic analysis of source codes by using machine learning to identify secret information by utilizing the network environment of
Further, SCPA device 202 is illustrated as being able to access a processed source codes repository 206(1) and a training data and machine learning models database 206(2). The source code predictive analytics module 302 may be configured to access these databases for implementing a method for facilitating automatic analysis of source codes by using machine learning to identify secret information.
The first client device 208(1) may be, for example, a smart phone. Of course, the first client device 208(1) may be any additional device described herein. The second client device 208(2) may be, for example, a personal computer (PC). Of course, the second client device 208(2) may also be any additional device described herein.
The process may be executed via the communication network(s) 210, which may comprise plural networks as described above. For example, in an exemplary embodiment, either or both of the first client device 208(1) and the second client device 208(2) may communicate with the SCPA device 202 via broadband or cellular communication. Of course, these embodiments are merely exemplary and are not limiting or exhaustive.
Upon being started, the source code predictive analytics module 302 executes a process for facilitating automatic analysis of source codes by using machine learning to identify secret information. An exemplary process for facilitating automatic analysis of source codes by using machine learning to identify secret information is generally indicated at flowchart 400 in
In the process 400 of
At step S404, the source code file may be parsed to identify at least one training feature. In an exemplary embodiment, the source code file may be translated from a raw file format to a structured file format prior to parsing. The translation of the source code file may enable processing of various computing languages such that the parsing action is file type agnostic. In another exemplary embodiment, the source code file may be tokenized to facilitate structuring of the source code file. Tokenizing the source code may include demarcating and/or classifying sections of a line of source code based on a predetermined requirement. For example, a line of source code may be tokenized to remove unnecessary elements such as, for example, white spaces and formatting characters. In another exemplary embodiment, each line of the source code file may be transformed into a numeric feature vector that is usable to train a machine learning classification model to predict a classification for each line. The transformation of the source code file may include specific preprocessing steps such as, for example, replacing numbers with constants, splitting camel-case words, lowercasing alphabetic characters, and stripping accents.
In another exemplary embodiment, the training feature may include at least one from among a token feature, an entropy-based feature, a structural feature, and a file type feature. The token feature may correspond to a count of tokens in the detections, the entropy-based feature may correspond to how random the string of characters is, the structural features may correspond to a logical structure of methods in the source code, and the file type feature may correspond to a file type of the source code file. In another exemplary embodiment, the training feature may include a measurable property of a phenomenon. The training feature may include numeric, alphabetic, and symbolic characters that together comprise the source code file.
In another exemplary embodiment, the entropy-based feature may be computed based on password strength, entropy bits, and residual strength. The password strength may be computed by using a custom function to normalize entropy bits to a range such as, for example, 0 to 1, which starts linear and becomes gradually more non-linear as entropy bits increases compared to some predetermined threshold.
Moreover, the entropy bits may be computed based on the entire line input from the detected secret. The entropy bits may be a sub-feature to the strength as outlined above. The entropy bits may correspond to information entropy of a value such as, for example, a password in integers, or equivalently the log (base 2) of the number of possible passwords of that string, assuming a random selection process for each character.
Additionally, the residual strength may be computed based on a subset of the line from the detected secret. Since functions relating to strength and entropy bits are computed on the entire line, the functions often include text that are not actually part of the password. To resolve this, the residual strength function may first split the line into tokens by using a splitting logic. Then, tokens that already exists in a vocabulary may be filtered out resulting in creation of a new string of unseen tokens. The new string of unseen tokens, i.e., the residual string may then be computed to determine the strength consistent with disclosures in the present application.
At step S406, a predetermined label may be associated with the training feature. The predetermined label may correspond to at least one from among a secret label and a non-secret label. In an exemplary embodiment, the predetermined label may include a weakly supervised label. The weakly supervised label may correspond to at least one from among a first label that results from regular expression patterns and a second label that results from distant supervision of an external knowledge base. In another exemplary embodiment, the secret label may describe information in the source code that is required to be hidden based on a business guideline. For example, the information may include a password, an application programming interface (API) key, and a username.
At step S408, a model may be trained by using the training feature and the corresponding predetermined label. In an exemplary embodiment, the training may include optimizing a hyperparameter by using a validation set. The hyperparameter may relate to the training feature and the corresponding predetermined label. In another exemplary embodiment, the hyperparameter may correspond to a machine learning parameter whose value may be used to control the learning process. The hyperparameter may include a configuration that is external to the model and whose value may not be estimated from training data.
In another exemplary embodiment, the model may include at least one from among a machine learning model, a statistical model, a mathematical model, a process model, and a data model. The model may also include stochastic models such as, for example, a Markov model that is used to model randomly changing systems. In stochastic models, the future states of a system may be assumed to depend only on the current state of the system.
In another exemplary embodiment, machine learning and pattern recognition may include supervised learning algorithms such as, for example, k-medoids analysis, regression analysis, decision tree analysis, random forest analysis, k-nearest neighbors analysis, logistic regression analysis, 5-fold cross-validation analysis, balanced class weight analysis, etc. In another exemplary embodiment, machine learning analytical techniques may include unsupervised learning algorithms such as, for example, Apriori analysis, K-means clustering analysis, etc. In another exemplary embodiment, machine learning analytical techniques may include reinforcement learning algorithms such as, for example, Markov Decision Process analysis, etc.
In another exemplary embodiment, the model may be based on a machine learning algorithm. The machine learning algorithm may include at least one from among a process and a set of rules to be followed by a computer in calculations and other problem-solving operations such as, for example, a linear regression algorithm, a logistic regression algorithm, a decision tree algorithm, and/or a Naive Bayes algorithm.
In another exemplary embodiment, the model may include training models such as, for example, a machine learning model which is generated to be further trained on additional data. Once the training model has been sufficiently trained, the training model may be deployed onto various connected systems to be utilized. In another exemplary embodiment, the training model may be sufficiently trained when model assessment methods such as, for example, a holdout method, a K-fold-cross-validation method, and a bootstrap method determine that at least one of the training model's least squares error rate, true positive rate, true negative rate, false positive rate, and false negative rates are within predetermined ranges.
In another exemplary embodiment, the training model may be operable, i.e., actively utilized by an organization, while continuing to be trained using new data. In another exemplary embodiment, the models may be generated using at least one from among an artificial neural network technique, a decision tree technique, a support vector machines technique, a Bayesian network technique, and a genetic algorithms technique.
At step S410, a test file may be received via a graphical user interface. The test file may include a set of source codes. In an exemplary embodiment, the test file may include a software program in development that a developer submits for testing consistent with disclosures in the present application. For example, prior to publishing, the developer may interact with the graphical user interface to provide the software program for testing to determine whether secret information has been inadvertently added in the source code. In another exemplary embodiment, the test file may include a published software program that is currently in use. An administrator may interact with the graphical user interface to provide the published software program for testing. For example, as part of an auditing process, an administrator may select the published software program for further evaluation consistent with disclosures in the present application. In another exemplary embodiment, the test file may include a data file such as, for example, a configuration file, a read me file, a commit history file, a list dependencies present file, a database schemas file, a structured query language (SQL) file, etc.
At step S412, the set of source codes in the test file may be parsed to identify at least one feature. Consistent with disclosures in the present application, the set of source codes may be translated from a raw file format to a structured file format prior to parsing. The translation of the set of source codes may enable processing of various computing languages such that the parsing action is file type agnostic. In another exemplary embodiment, the source code file may be tokenized to facilitate structuring of the set of source codes. Tokenizing the set of source codes may include demarcating and/or classifying sections of a line of source code based on a predetermined requirement. For example, a line of source code may be tokenized to remove unnecessary elements such as, for example, white spaces and formatting characters. In another exemplary embodiment, the set of source codes may be transformed based on specific preprocessing steps such as, for example, replacing numbers with constants, splitting camel-case words, lowercasing alphabetic characters, and stripping accents.
Consistent with disclosures in the present application, the feature may include at least one from among a token feature, an entropy-based feature, a structural feature, and a file type feature. As will be appreciated by a person of ordinary skill in the art, the feature may include a measurable property of a phenomenon. The feature may include numeric, alphabetic, and symbolic characters that together comprise the set of source codes.
At step S414, a first characteristic of the feature may be determined by using the model. The first characteristic may be determined in real-time by using the model. In an exemplary embodiment, the first characteristic may include at least one from among a secret characteristic and a non-secret characteristic. The secret characteristic may relate to information in the set of source codes that is required to be hidden based on a business guideline. For example, the information may include a password, an application programming interface (API) key, and a username. In another exemplary embodiment, the first characteristic may relate to a binary classification of a token that corresponds to the feature.
In another exemplary embodiment, a second characteristic of the feature may be determined by using the model. The second characteristic may be determined based on a first attribute of the first characteristic. The second characteristic may include at least one from among an obsolete characteristic, a usable characteristic, and a deprecated characteristic. For example, when a probability is high enough that a first characteristic is a secret characteristic, then the potential secret characteristic is passed to a second classifier that determines whether the secret characteristic is obsolete, usable, and/or deprecated.
In another exemplary embodiment, a third characteristic of the feature may be determined by using the model. The third characteristic may be determined based on a second attribute of the second characteristic. The third characteristic may include at least one from among a production characteristic and a development characteristic. For example, when the secret characteristic is deemed usable with a sufficiently high probability, then a third classifier may be used to detect whether the line of source code is a production or a non-production secret.
In another exemplary embodiment, a fourth characteristic of the feature may be determined by using the model. The fourth characteristic may be determined by the model when the third characteristic corresponds to the production characteristic. The fourth characteristic may include a production privilege level such as, for example, a low level or a high level. For example, when the secret characteristic is a production secret with a sufficiently high probability, then a fourth classifier may be used to determine the level of privilege that pertains to the secret in the production environment.
In another exemplary embodiment, a fifth characteristic of the feature may be determined by using the model. The fifth characteristic may be determined by the model when the third characteristic corresponds to the development characteristic. The fifth characteristic may include a development privilege level such as, for example, a low level or a high level. For example, when the secret characteristic is a development environment secret with a sufficiently high probability, then a fifth classifier may be used to determine the level of privilege that pertains to the secret in the development environment.
In another exemplary embodiment, a risk weighting value may be determined by using the model. The risk weighting value may be determined based on at least one from among the first characteristic, the second characteristic, the third characteristic, the fourth characteristic, and the fifth characteristic. Then, a severity level may be assigned to the feature based on the determined risk weighting value. For example, the secret characteristic may be assigned a risk weighting value depending on where the feature ends up with respect to leaf nodes of a probability tree. When the secret is production with a high privilege, the risk weighting value may be highest, i.e., a severe value. When the secret is a low privilege development secret, the risk weighting value may be low, i.e., a low value. When the feature is non-secret, the risk weighting value may be the lowest value, i.e., a baseline value.
In another exemplary embodiment, a course of action for the feature may be automatically identified. The course of action may be automatically identified by using the model based on the assigned severity level and the corresponding risk weighting value. For example, the detections from the classifier may be automatically resolved based on a human-in-the-loop implementation. The identified course of action may be automatically initiated, and a new test file may be automatically generated based on a result of the initiating. The new test file may then be executed to determine whether the new test file is operable. For example, a pull request may be automatically created to execute a build test and/or a unit test on the new test file to ensure that breaking changes are not made by the identified course of action. Then, a user may be notified via the graphical user interface. In another exemplary embodiment, the notification may include information that relates to the identified course of action, the assigned severity level, the new test file, and a result of the determined operability. For example, a developer may be emailed to request approval for the pull request.
In another exemplary embodiment, an input from the user may be received via the graphical user interface. The input may include manual attestation data that corresponds to one of the characteristics of the feature. Then, the model may be retrained by using the received input. Consistent with disclosures in the present application, the model may include at least one from among a machine learning model, a statistical model, a mathematical model, a process model, and a data model.
