AI as a change agent for security

1. AI as a change agent for security

In this video we will explore how AI can enhance organizational security, as well as the risks that it may bring.

2. AI-powered security

AI's role in an organization's security can be significant, rapidly processing vast amounts of data, quickly identifying threats, and learning from its findings. This allows analysts to focus on more complex tasks. Let's have a look at some common AI applications in security.

3. Automated anomaly detection

Automated anomaly detection is one example of how AI can augment security. To uncover irregular patterns, it can sift through various data like network activity, user behaviors, and system logs. This is crucial because these could be warning signs of various threats, such as malware, unauthorized access, or fraud. An example of this is user and entity behavior analytics, or UEBA, tools. They use AI to study patterns of user behavior, looking for irregularities. This helps pinpoint compromised accounts or flag people within an organization who may pose security risks.

4. Threat Intelligence Platforms (TIPs)

Risk and threat intelligence platforms, or AI-powered TIPs, are a second use case. TIPs analyze threat intelligence data to recognize the "who," "why," "how," and "what next" of potential threats. It helps organizations understand attackers' motivations, tactics, and techniques. This enables organizations to prepare for potential attacks and stay one step ahead of relevant risks.

5. Security Orchestration, Automation, Response (SOAR)

Security orchestration, automation, and response, or SOAR tools, are other examples of how AI is used in platforms. These tools use AI to streamline and synchronize security tasks across different systems, such as security log analysis, threat containment, and security patch management. This allows experts to direct their focus on tackling more sophisticated threats.

6. Security Information and Event Management (SIEM)

Finally, AI can increase the efficacy of security information and event management systems, or SIEMs. SIEMs analyze real-time security event data to identify anomalies, find patterns, and flag potential security incidents. Adding AI introduces new functionalities and enhances existing ones.

7. AI-powered SIEM

AI capabilities like machine learning and advanced data correlation enable SIEMs to identify complex security threats and anomalies more efficiently than traditional methods. This translates to faster incident detection, improved threat prediction, and the generation of actionable insights for security teams.

8. Faster, smarter, more secure

Let's look at an example of a bank integrating AI with its SIEM. The SIEM detects unusual patterns in international wire transfers. For instance, sudden transfers to rarely used accounts in high-risk countries at unusual times. The AI, trained on past fraud attempts, analyzes the wire transfer details in real time. It flags potentially fraudulent activity faster and more accurately than a manual review. The bank can investigate immediately, minimizing potential losses.

9. Huge upside, but with new risks

Despite its potential to revolutionize security, AI also carries certain risks. In the previous video, we discussed AI bias, data manipulation, and sensitive data exposure. Besides these factors, there are also ethical and accountability considerations when using AI in security. Accountability for AI in security can be very challenging. Because it is difficult to understand how some systems make decisions, it can be hard to know who is responsible for them.

10. Ethical dilemmas

The decision to use AI can bring ethical dilemmas. For instance, using facial recognition in surveillance can produce unfair results for specific groups and raise privacy concerns. Thus, the benefits of its use must be carefully considered against these drawbacks.

11. AI must be adopted carefully

In conclusion, although AI can be invaluable in security, it must be adopted carefully. Before introducing AI to support an organization’s security efforts, it is crucial to know and mitigate any related risks. As we will see in the upcoming chapters, it’s important to embrace both AI's potential and the new responsibilities that it brings.
