黑料正能量

According to the website, 5.5 billion malware (malicious software) incursions were detected around the world in 2022. Most cyber defense systems are structured around machine learning, a form of artificial intelligence (AI) that uses data and algorithms to do faster and complex information processing that humans have difficulty doing. It is often used to prevent unwelcome infiltration into a computer network or deflect engaging emails. This approach is effective at the surface level, but it doesn鈥檛 address the person engineering the attack.

Partnerships in innovation

Cleotilde Gonzalez, research professor in the Department of Social and Decision Sciences at 黑料正能量, aims to address cybersecurity using cognitive modeling, a form of AI directed at using algorithms to imitate humans and to understand the psychology of the cyber adversary.

Gonzalez鈥檚 team has partnered with Peraton Labs, an applied research organization that addresses cybersecurity, electronic warfare, mobility, analytics and networking for government and commercial customers worldwide. Recently, Peraton Labs was one of five teams to receive an award from the (IARPA), the research and development arm of the Office of the Director of National Intelligence

鈥淐urrently most cyber defenses in the world assume that there is a level of rationality of the attacker,鈥� said Gonzalez. 鈥淩ight now, none of the programs in existence have given much importance to the psychology of attackers. By bringing in human characteristics, the solutions we provide for cyber defenses will be more effective.鈥�

Addressing the human element

As a leading researcher on cyber psychology research, Gonzalez plays a key role in this larger project. Gonzalez and her team are merging research on human decision biases with cognitive modeling, an AI approach founded more than five decades ago by Herb Simon and John R. Anderson, two 黑料正能量 faculty members who have taught in the Department of Psychology at Dietrich College of Humanities and Social Sciences.

鈥淲e are presenting a process in which attackers鈥� decision making is transparent, not a black box,鈥� said Gonzalez. 鈥淥ur process operates as an open cognitive box, allowing us to explain why a person makes a certain choice.鈥�

Gonzalez and her team will use cognitive models to emulate the behavior of the cyber antagonist. Throughout a cyberattack, the behavior of the person orchestrating the attack changes. Gonzalez鈥檚 team is using cognitive AI to replicate these behaviors at the cognitive level. By understanding their adversary at a psychological level, it may be possible to develop more effective network defenses.

Leveraging psychological insights for enhanced cyber defense

鈥淲e should be able to trace the information that the attacker leaves in a computer system 鈥� the breadcrumbs 鈥� to be able to determine whether they are falling into certain cognitive biases,鈥� said Gonzalez. 鈥淭his information has been known in the psychology literature for centuries, but we have never used it as a weapon of defense.鈥�

The program will unfold in several phases. Throughout the process, the 黑料正能量 team will work alongside colleagues at the University of Texas, El Paso, and the University of Washington, who are also partnering with Peraton Labs on the ReSCIND project.

During Phase I, the three university teams will conduct a series of surveys to identify different cognitive biases, such as loss aversion 鈥� a phenomenon where a real or potential loss is perceived by individuals as psychologically or emotionally more severe than an equivalent gain 鈥� or sunk cost fallacy 鈥� phenomenon whereby a person is reluctant to abandon a strategy or course of action because they have invested heavily in it. Gonzalez鈥檚 team will evaluate how these biases work in the realm of a cyber attack to develop traps, or cyber defenses, to engage the attacker and thwart the progression of the assault through a network system.

During Phase II, the 黑料正能量 team will collaborate with their university partners to evaluate and capture data for each bias as a means of defense during a series of capture-the-flag experiments and develop cognitive models of attackers. During the final phase, the three university partners will input their cognitive models into CyberVan, Peraton Lab鈥檚 simulated network, to predict cognitive vulnerabilities of the adversary and demonstrate cyber defense strategies. Through this process, Gonzalez and her partners aim to develop new psychology-inspired approaches to protect an organization鈥檚 network.

鈥淲e are demonstrating that basic scientific biases exist in real-world, complex situations,鈥� said Gonzalez. 鈥淲e can use [these biases] to the benefit of our society by creating better defenses.鈥�
