Researchers develop automated approach to extract security policies from software
A platoon of UTSA experimenters is exploring how a new automated approach could help software security vulnerabilities.
The platoon — made up of Ram Krishnan, associate professor in the UTSA Department of Electrical and Computer Engineering; Yufei Huang, professor in Electrical and Computer Engineering; Jianwei Niu, professor in Computer Science; Ravi Sandhu, professor and Lutcher Brown Distinguished Chair in Cyber Security; and John Heaps, a postdoctoral experimenter in the UTSA Institute for Cyber Security — sought to develop a deep literacy model that could educate software how to prize security programs automatically.
Unlike traditional software models, the nimble software development process is meant to produce software at a faster pace, barring the need to spend time on comprehensive documents and changing software conditions. Stoner stories, the specifications that define the software’s conditions, are the only needed attestation. Still, the practices ingrain to this process, similar as constant changes in law, limit the capability to conduct security assurance reviews.
“The introductory idea of addressing this dissociate between security programs and nimble software development came from occurrence discussion with software leaders in the assiduity, “Krishnan said. “We were suitable to assemble a platoon of faculty and scholars with moxie in cybersecurity, software engineering and machine literacy to start probing this problem and develop a practical result.”
The experimenters looked at different machine learning approaches before settling on a deep literacy approach, which can handle several formats of stoner stories. The model consists of three pieces to perform the vaticination Access control groups, named reality recognition and access type bracket. Access control bracket helps the software decide if stoner stories contain access control information. Named reality identifies the actors and data objects in the story. The access type bracket determines the relationship between the two.

The platoon took a data set of 21 web operations, each conforming of 50-130 stoner stories, or aggregate, to test their approach.
“With a dataset of stoner stories, we developed a literacy model grounded on mills, a important machine learning fashion, “Krishnan said. “We were suitable to prize security programs with good delicacy and fantasize the results to help stakeholders more upgrade stoner stories and maintain an overview of the system’s access control.”
This innovative new approach will serve as a precious tool in the ultramodern nimble software development life cycle, Krishnan said.
“Since nimble software development focuses on incremental changes to law, a homemade process of rooting security programs would be error-prone and burdensome,” he added. “This is yet another area where machine literacy/ artificial intelligence shows to be a important approach.”
Krishnan said the platoon still has several directions they would like to take the design.
“We fete that there’s little fresh information about access control that can be uprooted or determined directly from stoner stories in a completely automated approach, “Krishnan said. “That means it’s delicate, or insolvable, to determine a software’s exact access control from stoner stories without mortal involvement. We plan to extend our approach to make it interactive with stakeholders so that they can help upgrade the access control information.”
