Introduction
Data security is more important today than ever before. As organizations collect and store more sensitive customer data, cybercriminals work to steal that data for profit. Fortunately, artificial intelligence (AI) is transforming data security in incredible ways. In this article, I will explore how AI is revolutionizing data security across three key areas:
Detecting Emerging Threats
One of the biggest challenges in data security is detecting new threats that evade traditional security tools. AI and machine learning allow security teams to identify these novel attacks much faster.
Here’s how it works:
-
AI systems are trained on millions of samples of normal network traffic and known cyber attacks. This allows the AI to learn the patterns of typical system activity versus malicious activity.
-
The AI can then monitor network traffic and system logs in real-time to detect anomalies – activity that deviates from the norm. This enables the AI to flag potential zero-day threats and emerging attack vectors.
-
For example, if an AI system notices outbound network traffic with an unusual destination, it can block the traffic and alert security analysts. This quick threat detection stops attacks before they compromise sensitive data.
According to a recent study by Capgemini, AI-enabled cybersecurity tools detect 10% more security incidents than traditional tools. The faster an attack is identified, the less damage it can inflict.
Prioritizing Security Operations
Another key application of AI is automating the triage and prioritization of security alerts. Traditional security tools often produce thousands of alerts each day, overwhelming security teams. AI helps make sense of this flood of data.
-
AI algorithms can analyze hundreds of attributes of each security alert – IP address, timestamp, attack type, target system, etc. The AI can correlate these details across historical alerts to prioritize the most critical threats.
-
For instance, if an IP address is associated with previous malicious activity, any new alerts involving that IP will be escalated. This allows security teams to focus on alerts that pose the greatest risk.
-
According to IBM research, AI reduces false positives from security tools by up to 95%. This significantly cuts the noise and helps security staff pinpoint the real attacks.
Protecting Sensitive Data
In addition to improving threat detection, AI also enables more proactive protection of sensitive customer data.
-
AI-powered data loss prevention (DLP) tools use machine learning to automatically discover sensitive data repositories across an organization’s systems. This allows security teams to properly classify and secure sensitive data.
-
AI can also monitor user activity and communications for signs of risky behavior – like an employee emailing customer lists to a personal account. The AI can flag these activities as potential data exfiltration attacks, preventing data from leaving the organization.
-
For example, Darktrace’s AI-enhanced DLP can detect insider threats in real time with up to 92% accuracy. This prevents breaches before critical data is compromised.
Conclusion
From recognizing novel zero-day attacks to proactively securing sensitive data, AI is transforming data security. These intelligent technologies enable security teams to keep pace with rapidly evolving threats and massive amounts of security data. While AI alone can’t eliminate cyber risk, it provides unparalleled improvements in monitoring, detection, and response capabilities. With AI as a key component of modern security strategies, organizations can protect their critical information assets now and into the future.
