A computer-implemented method is presented for extracting data from textual records. The objective of the disclosure is to identify the most appropriate pattern in a set of patterns for extracting data from data records and by applying the most appropriate pattern to a plurality of data records, to robustly extract data from textual records.

A unified storage format is presented for received observation data records of various formats, including individual observations or histograms and pre-sampled records describing multiple observations. The proposed storage format also supports various data reduction technologies, including coarsening of time and observation value resolutions, where the proposed data reduction technologies retain data describing the quantity of observations. In addition, sampling-based data reduction approaches are described, which at least retain the statistical expectancy value for the number of observations. Further, a definition and storage format for histogram buckets is provided with guaranteed relative error behavior over the whole value range of observation data, that only requires the definition of a number of significant bits for the recording and interpretation of histogram data. The proposed histogram storage scheme is applicable to integer and floating-point observation data. (Fig. 1)

The present disclosure relates to the detection of cross-site scripting vulnerabilities in a web application. The objective of the disclosure is to find a computer-implemented method for detecting cross-site scripting vulnerabilities in a web application. The detection of XSS vulnerabilities shall be performed automatically and the number of false positives shall be reduced compared to the prior art.

A technology is disclosed for automated risk analysis for the deployment of software component updates in complex microservice architectures. Dependencies and versions of deployment situations in test setup environments and in a target environment are analyzed and compared to identify a version delta between tested and production deployments. Further, test results for test deployments are used to identify and remove unsuccessful test setups. Successful test setups are ranked according to extend of their version delta against the target environment and one of the successful test setups is selected according to a deployment strategy. After a test setup is selected, a deployment plan considering service versions and dependencies is generated that guarantees a tested and functional state of the target environment after each deployment step.

A computer-implemented method is presented for identifying vulnerable software from a computer system. The method includes: identifying name of a given software component in a vulnerability database by analyzing text of an entry in the vulnerability database using a large language model, where entries in the vulnerability database have known vulnerabilities; identifying a patch for the given software component in a source code repository by analyzing text of the entry in the vulnerability database using the large language model; identifying the patch for the given software component in the source code repository by analyzing text in the source code repository using the large language model; and reporting the given software component as being vulnerable in response to identifying the patch for the given software component in the source code repository.
