Este trabalho da Microsoft representa uma conexão significativa entre a inteligência artificial (IA) e o mundo tecnológico prático. A Microsoft está se tornando, rapidamente, uma especialista na aplicação criteriosa da IA a problemas reais e prementes. Devido ao escopo de visibilidade que têm em questões de segurança, abrangendo de kernels brutos até a camada de aplicativos, as empresas de software estão muito bem posicionadas para assumir a liderança em segurança, e isto reafirma tal vantagem.

É exatamente por causa de serviços assim que os provedores de nuvem pública estão tão à frente. As grandes empresas são capazes de combinar o conhecimento das diversas áreas em que atuam, produzindo competências únicas que os outros não conseguem replicar. Isso não é novidade, mas deve servir como lembrete de que a especialização é o caminho a ser trilhado, pois a infraestrutura e os serviços relacionados são continuamente comoditizados. Aproveite esses serviços em vez de construí-los por conta própria e use o tempo extra para desenvolver competências diferenciadas no seu setor.

Microsoft has released an artificial intelligence (AI)-powered tool to help developers categorise bugs and features that need to be addressed in forthcoming releases.

The software giant's machine learning system classifies bugs as security or non-security with a 99% accuracy, and also determines whether a bug is critical or non-critical with a 97% accuracy rating.

With ambitions to build a system with a level of accuracy as close as possible to a security expert, Microsoft fed its machine learning model with bugs labelled as security and non-security. Once this was trained, it could then label data that was not pre-classified.

"Every day, software developers stare down a long list of features and bugs that need to be addressed," said Microsoft’s senior security program manager Scott Christiansen, and data and applied scientist Mayana Pereira.

"Security professionals try to help by using automated tools to prioritize security bugs, but too often, engineers waste time on false positives or miss a critical security vulnerability that has been misclassified.

"At Microsoft, 47,000 developers generate nearly 30 thousand bugs a month. These items get stored across over 100 AzureDevOps and GitHub repositories. To better label and prioritize bugs at that scale, we couldn’t just apply more people to the problem. However, large volumes of semi-curated data are perfect for machine learning."

Because the system needs to be as accurate as a security expert, security professionals approved training data before this was fed into the machine learning model. Once the model was operational, they were brought back to evaluate the model in production.

The project began with data science and the collection of all data types and sources to evaluate quality. Security experts were then brought in to review the data and confirm the labels assigned were correct.

Data scientists then chose a modelling technique, trained the model, and evaluated performance. Finally, security experts evaluated the model in production by monitoring the average number of bugs and manually reviewing a random sample.

The mechanism uses a step-step machine learning model operation; first learning how to classify between security and non-security bugs and then to apply a severity rating.

As a result of the level of accuracy, Microsoft now believes it’s catching more security vulnerabilities before they are exploited in the wild.

Development teams can read details in a published academic paper, with the machine learning methodology set to be open-sourced through GitHub in the coming months.
