How Does AI Cybersecurity Work?
AI in cybersecurity works through AI algorithms, machine learning, and neural networks that are capable of analyzing massive amounts of data to detect patterns and anomalies indicative of cyberattacks. Furthermore, AI helps to scan the entire network to identify loopholes to prevent cyberattacks in the future. Here is a simplified workflow to understand the use of AI in cybersecurity:
1. Gathering the Data: AI algorithms use various sources to gather the required data. Some of the prominent sources for data collection include user behavior, system logs, and network traffic.
2. Processing the Data: The collected data is then filtered and processed to eliminate irrelevant information. Processing of data involves a reduction of noise in the data.
3. Training the AI Model: AI algorithms are then trained to recognize normal behavior and then look out for anomalies and abnormal activities, which deviate from normal behavior.
4. Detection of Threats: The trained AI model, algorithms, and neural networks monitor massive amounts of real-time data to identify threat patterns, assisting in the detection and prevention of threats.
5. Response to Abnormalities: Upon identifying a threat to the system, the automated AI algorithm intimates the human security analysts about the potential software attack. They tend to block malicious IP addresses and email senders to stop attacks like phishing.
Artificial Intelligence Vs. Data Analytics
Though AI in cybersecurity and data analytics in cybersecurity play a crucial role in detecting, preventing, and responding to cyberattacks, they both differ in their approaches and their respective capabilities. Undoubtedly, advances in AI are redefining how cybersecurity works. AI focuses on the creation of machines and systems that are capable of performing tasks that otherwise require human intelligence.

Traditional Cybersecurity vs Modern AI-Driven Approaches
Traditional approaches to cybersecurity rely on the application of perimeter defense to protect the network, application, and data of an organization. Traditional approaches include functional tools such as firewalls and the setting up of presumptive trusted zones within the perimeter. This approach relies on predefined rules to identify threats. This approach is useful only in case of known threats. However, it tends to fail with new and evolving threats. In contrast to this, modern AI-driven approaches to cybersecurity are adaptable as they do not follow rule-based static systems and can learn about new threats. Furthermore, Artificial Intelligence Cybersecurity has reduced the response time significantly because AI processes real-time data at a very fast speed. In comparison to traditional approaches, AI-driven approaches are more scalable as they can easily scale to protect huge networks without much involvement of humans. Also, modern-day approaches have come up with predictive analytics, which assists in the prediction and mitigation of threats and attacks before they actually occur. This highlights the fact that traditional approaches are reactive in nature, whereas Artificial Intelligence Cybersecurity is proactive in nature.
