Artificial Intelligence (AI) in Cybersecurity
AI in Cybersecurity
Artificial intelligence (AI) broadly refers to any human-like behavior displayed by a machine or system that enables it to perform a function or complete a task. In AI’s most basic form, computers are programmed to “mimic” human behavior using extensive data from past examples of similar behavior. AI enables computers to make decisions that allow them to act on their own without human input and take care of routine tasks like maintenance without human intervention.
What is AI in cybersecurity?
Artificial intelligence (AI) has been a game-changer in many industries including cybersecurity. With the power of AI, security solutions can offer organizations many benefits including stronger protection against cyberattacks, lower payroll costs and increased cyber resilience. 41% of companies employ AI security tools like automated email security.
Why is cybersecurity AI important?
Cyber threats become more complex and sophisticated every day as cybercriminals evolve their tactics through social engineering. That’s bad news for businesses – an estimated 97% of employees are unable to detect a sophisticated cyberattack attempt like a spear phishing message. But AI isn’t fooled by cybercriminals tricks, enabling it to spot cybersecurity threats that humans can’t.
How is AI used in cybersecurity?
AI is often used as an umbrella term that encompasses the technology behind many smart solutions and devices. It’s a constantly evolving field with new innovations emerging regularly. These terms are often used in discussions about AI.
Machine learning (ML), which is sometimes used interchangeably with AI, refers to the process by which computers develop pattern recognition, or the ability to continuously learn from and make predictions based on data, then make adjustments without being specifically programmed to do so. Machine learning collects, organizes and structures data, ensuring that AI has the information that it needs to plug into its algorithm.
Deep learning is a subset of machine learning (ML), which is itself a subset of artificial intelligence (AI). The concept of AI has been around since the 1950s, with the goal of making computers able to think and reason in a way similar to humans. As part of making machines able to think, ML is focused on how to make them learn without being explicitly programmed. Deep learning goes beyond ML by creating more complex hierarchical models meant to mimic how humans learn new information.
A neural network is a method in artificial intelligence that teaches computers to process data in a way that is inspired by the human brain. It is a type of machine learning process, called deep learning, that uses interconnected nodes or neurons in a layered structure that resembles the human brain. It creates an adaptive system that computers use to learn from their mistakes and improve continuously. Thus, artificial neural networks attempt to solve complicated problems, like summarizing documents or recognizing faces, with greater accuracy.
Computer vision is a field of artificial intelligence (AI) that enables computers and systems to derive meaningful information from digital images, videos and other visual inputs — and take actions or make recommendations based on that information. If AI enables computers to think, computer vision enables them to see, observe and understand.
In artificial intelligence, an expert system is a computer system emulating the decision-making ability of a human expert. An expert system is divided into two subsystems: the inference engine and the knowledge base. The knowledge base represents facts and rules. The inference engine applies the rules to the known facts to deduce new facts. Inference engines can also include explanation and debugging abilities.
Natural Language Processing (NLP)
Natural language processing (NLP) combines computational linguistics, the rule-based modeling of human language, with statistical, machine learning and deep learning models. This enables computers to process human language in the form of text or voice data and to ‘understand’ its full meaning, complete with the speaker or writer’s intent and sentiment.
Is AI a benefit or threat to cybersecurity?
AI can be beneficial in cybersecurity, but it can also be a security threat that impacts cybersecurity in myriad positive and negative ways. Security automation and AI can save businesses more than 80% of the cost of manual security. Plus, AI and security automation enabled organizations to respond to breaches nearly 30% faster than companies without security automation.
However, there are downsides. IBM researchers identified a technique that cybercriminals can use to manipulate AI to serve their ends. In adversarial machine learning, AI systems’ neural networks are tricked by intentionally modified external data. An attacker ever so slightly distorts these inputs for the sole purpose of causing AI to misclassify them.
How does AI improve cybersecurity?
AI can improve an organization’s defenses in many important ways. Every business can reap the benefits of AI thanks to today’s affordable, automated security solutions.
Advanced Unknown Threat Hunting & Detection
AI-enabled tools are much more likely to spot a zero-day threat than conventional security tools because of their constant collection and analysis of fresh threat intelligence. Since AI doesn’t rely on threat reports to detect vulnerabilities, AI-enabled tools can come up with clues fast, leading to early detection of threats to prevent the attack.
Accelerated Incident Response Rates
AI and security automation enabled organizations to respond to breaches nearly 30% faster than companies without security automation.

Protection That Gets Smarter with Time
When businesses choose automated security solutions that utilize AI, their protection only gets better over time, preventing solutions from becoming obsolete quickly.
How is AI a threat to cybersecurity?
Unfortunately, advances in technology can also benefit the bad guys. Malicious hackers can leverage AI tools to enhance the precision and effectiveness of their attacks as well as find exploitable vulnerabilities. For example, they can use AI to bypass detection by having it learn the most common detection rules. Criminals can also use AI to conceal malicious codes in benign applications that they can execute later to enable a cyberattack.
The Information Systems Audit and Control Association (ISACA) cautions that AI can have a negative impact on data privacy, pointing out that the AI processing of personal data can impinge on individuals’ rights and freedoms. ISACA lists several privacy challenges of AI including, data persistence (data existing longer than the human subjects that created it, driven by low data storage costs), data repurposing (data being used beyond their originally imagined purpose) and data spillovers (data collected on people who are not the target of data collection).
What companies use AI in cybersecurity?
Companies have been making use of AI for decades because it’s a flexible, dynamic tool that can be used in so many ways. Some cybersecurity companies specialize in AI-driven security solutions, while others make use of AI to improve performance and add automation options to more conventional security solutions.
