The role of AI in improving cloud detection and response (SEC105)

Summarizing the Video Transcript

Introduction

  • The speaker is James Hall, a Cloud Solutions Architect at Darktrace, a cybersecurity company based on AI.
  • The talk will cover the role of AI in improving cloud detection and response, the evolution of AI technology, and the introduction of cloud detection and response to address security concerns.

The Evolution of AI Technology

  • In the 2010s, AI was adopted by innovators and early industry adopters, leading to the development of solutions by cloud service providers.
  • In the early 2020s, the creation of large language models and generative AI made the technology easily accessible to everyone, enabling simple research and automation of tasks.
  • This increased accessibility raises concerns about the potential for AI to speed up the pace of attacks.

The Cyber Kill Chain and AI

  • The cyber kill chain, consisting of reconnaissance, weaponization, delivery, and other steps, can be accelerated by the use of AI.
  • Threat actors can leverage AI for reconnaissance, such as using web scrapers and publicly accessible domains to target organizations.
  • AI can also be used for weaponization, with supervised machine learning systems adapting to various endpoints.

The Need for Advanced Cloud Security

  • Current security approaches often involve point solutions and manual investigation, which can be time-consuming and inefficient.
  • As companies migrate to the cloud, the attack surface expands, and unique cloud-based threats arise.
  • There is a need for advanced security solutions that can detect, investigate, and respond to threats quickly.

Cloud Detection and Response

  • Cloud detection and response is built on three core pillars: detection, investigation, and response.
  • Detection involves processing large amounts of data from disparate platforms and identifying correlations between alerts.
  • Investigation and response aim to provide suggestive or automated actions to help security teams resolve issues quickly.

Leveraging AI and Machine Learning

  • AI and machine learning are crucial for cloud detection and response.
  • Supervised and unsupervised machine learning models can be used to establish a baseline of normal activity in an organization and detect both known and unknown threats.
  • This approach can help security teams keep up with the speed of AI-powered attacks by automating and correlating threat detection, investigation, and response.

The Benefits of AI-Driven Cloud Security

  • Reduced time to meaning: AI can quickly correlate threats and generate clear, actionable reports for security teams.
  • Improved threat detection: The ability to detect both known and unknown threats, including insider threats.
  • Increased efficiency: AI-powered tools can help security teams manage a large attack surface and keep pace with the rapid creation of cloud assets.

The Future of AI in Cloud Security

  • The adoption of AI in everyday life highlights the need to leverage this technology to keep up with the dynamic and fast-paced nature of cyber threats.
  • By building a business-centric understanding of an organization's "pattern of life," AI-driven cloud security can proactively detect and respond to threats, both known and unknown.
