In the early hours of November 23, 2022, AIIMS in New Delhi suffered a ransomware attack. Attackers locked the data of over 40 million patients, disrupting services for two weeks. Just a month later, December brought RailYatri's own misfortune — a breach exposed sensitive user data, leaving questions unanswered and cybersecurity shaken.
What was missing in both cases? AI in data security! Had the companies made use of AI in cyber security, here's what could have happened.
- Long Short-Term Memory (LSTM) networks could've tracked ransomware patterns, stopping the AIIMS attack.
- Convolutional Neural Networks (CNNs) could've caught RailYatri's breach before it began.
So, you see? The role of AI in cyber security is pivotal. And that's precisely what this article talks about – how to strengthen cybersecurity with AI, key AI technologies, benefits of AI in network security, and more.
What is the Importance and Role of AI in Cybersecurity?
Did you know? According to Statista, the Indian Cyber Crime Coordination Centre (I4C) registered more than 7.4 lakh cyber crime cases between January 2024 and April 2024.
Cybersecurity threats are at an all-time high because cybercriminals are finding new ways to exploit digital systems daily. The scale and sophistication of cyber threats grow every day, making it harder for traditional security measures to keep up.
Here are a few of the most prevalent attacks on the rise.
- Phishing and spear-phishing scams that mimic real emails
- Ransomware attacks that can lock entire networks
- Brute force
- Social engineering
- IoT-targeted attacks
Traditional security methods, like simple firewalls or basic antivirus programs, can't keep up with these fast-evolving threats. That's because they rely on outdated databases of known attacks, which means new, modified, or hidden threats can slip by undetected.
This is where AI steps in as a crucial player.
When you lace cybersecurity with AI, here's what the latter does:
- Actively monitors, learns, and adapts.
- Analyzes patterns and anomalies in real-time.
- Detects suspicious activities that may indicate an attack, even if that threat hasn't been seen before.
To put it simply, the role of AI in cybersecurity goes beyond standard measures.
Here are the several distinct advantages that prove its importance.

2. AI for Behavioral Analysis and Anomaly Detection
One of AI's strengths is learning what "normal" looks like for each user or system and catching deviations from it.
Think of it as AI getting to know your digital habits.
- When you usually log in
- What data do you access
- Where do you do it from
Once it establishes this baseline behavior, it can spot even the smallest red flags, like logins from unexpected locations or access to sensitive data at strange hours. This feature helps protect against insider threats or unauthorized access that might otherwise go unnoticed.
This kind of behavioral analysis is essential for protecting sensitive information. By continuously monitoring and comparing activity to its learned baseline, AI successfully secures digital assets.

3. AI for Endpoint and Network Protection
AI also plays a crucial role in securing endpoints (like laptops and mobile devices) and monitoring network traffic. Nowadays, when remote work has become the lifeline of corporate jobs and endless smart devices have popped up, every connected device is a potential entry point for attackers.
AI-powered security tools monitor all these connections, analyzing data for signs of abnormal behavior, such as large data transfers or unusual device access.
AI's ability to monitor and protect multiple devices and networks at once is especially valuable in complex setups. It quickly identifies and isolates suspicious devices, stopping potential threats from spreading across the network.
What are the Advanced AI Techniques that Enhance Cybersecurity?
Integrating AI in network security proved to be a champion for a global financial service provider – unnamed to this date – a few years back. The service provider had used AI to mitigate threats stemming from the Log4j vulnerability.
The AI-deployed system detected unusual activity on its virtual desktop infrastructure (VDI) servers, which were being targeted by attackers attempting to exploit this critical vulnerability. The AI's rapid response helped contain the threat before it could spread throughout the network.
This is just one example of what the amalgamation of artificial intelligence and security can do.
But the question is – what are those advanced techniques that give AI the intelligence to nip dangerous cyber attacks in their bud? If that's what's occupying your mind, too, this section is a goldmine of answers. Have a look at the best techniques to watch out for and probably make a career in.
Machine Learning in Cybersecurity
Machine learning (ML) is a core component of AI's defense strategy against cyber threats. By analyzing large datasets, machine learning algorithms can identify patterns that may signal a security risk.
- With supervised machine learning, AI is trained using known threats, helping it spot similar attacks in the future.
- Unsupervised machine learning, on the other hand, identifies new patterns without prior knowledge, making it ideal for detecting unfamiliar or "zero-day" threats.
In practice, ML's adaptability allows it to learn from every encounter, refining its responses over time. This way, it becomes better at identifying potential threats and keeping systems secure even as attack strategies evolve.
Here's a real-life use case of machine learning in cybersecurity.

What is AI-Driven Automation in Cybersecurity?
AI-driven automation in cybersecurity refers to the integration of artificial intelligence into security to streamline routine tasks, assist in threat detection, and enable swift responses, often in real-time.
Rather than completely replacing human oversight, AI-driven automation complements the work of security teams, allowing them to focus on complex threats and strategic planning. At the same time, AI handles time-sensitive, repetitive tasks.
Let's now help you explore the many aspects of AI-driven cyber security in detail. Have a look.
1. Automated Security Controls and Incident Response
AI-driven automated controls allow cybersecurity systems to respond instantly to suspicious activities.
When a threat is detected, AI comes to life.
It triggers specific actions:
- Locking targeted accounts
- Blocking unauthorized access
- Isolating compromised systems
For example, if an unusual attempt to access sensitive data is detected, the AI can automatically lock the targeted account, alert security teams, and block further attempts from the source.
This kind of automation reduces reliance on human monitoring for each potential threat, allowing security teams to focus on more complex investigations and strategic planning while AI manages routine yet crucial defense tasks.
2. Security Information and Event Management (SIEM)
Security Information and Event Management (SIEM) systems gather security-related data from across an organization, tracking everything from logins to access patterns.
AI enhances SIEM capabilities by performing a few critical tasks.
- Analyzing data in real-time
- Pinpointing suspicious patterns
- Filtering out false positives
This ensures that alerts generated by the system reflect genuine threats that need immediate attention.
For example, AI-powered SIEM can differentiate between typical user behavior and suspicious access attempts, even flagging activities that deviate from established patterns. With AI's intelligent filtering, security teams can focus on high-risk incidents without being distracted by routine activity.
3. Predictive Analytics for Proactive Defense
Predictive analytics in cybersecurity uses AI to analyze historical data and anticipate future threats. This proactive approach allows organizations to prepare for attacks before they happen, applying targeted security measures to likely points of vulnerability.
For instance, if predictive analytics reveals an increase in phishing attempts targeting a specific department, AI can guide the security teams in the following ways.
- Enforce stricter email security for targeted department
- Help prevent a potential breach
In this way, AI-driven predictive analytics strengthens defenses in anticipation of emerging threats.
What are the Applications of AI in Identity and Access Management (IAM)?
Nowadays, securing user identities and managing access privileges have become crucial in cybersecurity. Why? Well, for one, as per reports by Microsoft, National Public Data suffered a terrible cybersecurity attack in early 2024. 2.9 billion user records were stolen, and almost 170 million people across countries were affected.
What's the solution, you ask? It's the use of AI in access management.
Identity and Access Management (IAM) is a framework of policies and technologies that ensures the right individuals have appropriate access to organizational resources. It involves managing digital identities and controlling who has access to specific data, systems, and applications within an organization.
AI enhances IAM by introducing dynamic security measures — enlisted below — that can adapt to new threats and support efficient and secure access controls.
1. Enhancing Authentication Mechanisms
