人工智能和机器学习对网络安全的影响

by MustafaAbdulhussein Dissertation SubmittedinPartialFulfillment LibertyUniversity,SchoolofBusiness February2024 Abstract As internet technology proliferate in volume and complexity, the ever-evolving landscape ofmalicious cyberattacks presents unprecedented security risks in cyberspace. Cybersecuritychallenges have been further exacerbated by the continuous growth in the prevalence andsophistication ofcyber-attacks. These threats have the capacity to disrupt business operations, erasecritical data, and inflict reputational damage, constituting an existential threat to businesses, criticalservices, and infrastructure.The escalating threat is further compounded by the malicious use ofartificial intelligence(AI) andmachine learning(ML), which have increasingly become tools in thecybercriminal arsenal.In this dynamic landscape, the emergence of offensiveAIintroduces a newdimension to cyber threats. The current wave of attacks is surpassing human capabilities,incorporating AI to outsmart and outpace traditional, rule-based detection tools. The advent of"offensive AI" allows cybercriminals to execute targeted attacks with unprecedented speed andscale, operating stealthily and evading conventional security measures.As offensive AI looms onthe horizon, organizations face the imperative to adopt new, more sophisticated defenses. Human-driven responses tocyber-attacks are struggling to match the speed and complexity of automatedthreats. In anticipation of this growing challenge, the implementation of advanced technologies,including AI-driven defenses, becomes crucial.This dissertation exploredthe profound impact ofbothAIandMLoncybersecurity in the United States. Througha qualitative, multiple case study,combining a comprehensive literature review with insights fromcybersecurityexperts, the researchidentifiedkey trends, challenges, and opportunities for utilizing AI incybersecurity.
