AI Cybersecurity

AI has revolutionized the way IT security professionals think about cybersecurity. Newer AI-powered cybersecurity  tools and systems have the ability to support providing even better data protection against threats by quickly recognizing behavior patterns, automating processes, and detecting anomalies.

AI in Cybersecurity

AI powered cybersecurity can monitor, analyze detect, and respond to cyber threats in real time. As AI algorithms analyze massive amounts of data to detect patterns that are indicative of a cyber threat, it can also scan the entire network for weaknesses to prevent common kinds of cyber attacks.

AI primarily monitors and analyzes behavior patterns.  Using these patterns to create a baseline, AI can detect unusual behaviors and restrict unauthorized access to systems.  AI can also help to prioritize risk, instantly detect the possibility of malware and intrusions before they begin.

When implemented properly, AI can serve as the engine for security automation, which frees up the time and resources of employees by automating repetitive tasks. AI can also reduce the occurrence of human error by removing humans from a task or process.

How Is AI Cybersecurity Different?

Cybersecurity protection with artificial intelligence will never fully replace security professionals, as there will always be a need for creative problem-solving and more complex challenges in the workplace. However, AI can and already does assist human security professionals by analyzing vast amounts of data, recognizing patterns, and creating insights based on large volumes of security data. This could take hours, sometimes weeks to complete with traditional security processes.

Before AI, security professionals used signature-based detection tools and systems to identify potential cyber threats. These security tools compare incoming network traffic to a database of known threats or malicious code signatures. Upon detection, the system triggers an alert and suggests to the security professional that they should take an action to block or quarantine the threat.

This signature-based security approach has been reasonably effective against known threats. However, the signature-based detection approach has proven to be inadequate against new (Zero-Day) or unknown threats. Too often, these tools also resulted in a higher frequency of false positives, which sent security professionals on a “wild goose chase.”

Traditional cybersecurity also relies heavily on manual analysis. Security analysts must manually investigate security alerts and event logs in search of any identifiable patterns that serve as indicators of a potential security breach. Investigating logs and events can take extensive amounts of time and relying solely on a single security analyst is a mistake companies cannot afford to make.

What Are the Risks of AI in Cybersecurity?

Like any technology, AI can be used for good or malicious purposes. Threat actors can use some of the same AI tools designed to help humanity to commit fraud, scams, and other cybercrimes.

1: Cyber attacks optimization 

Experts say that attackers can use generative AI and large language models to scale attacks at an unseen level of speed and complexity. They may use generative AI to find fresh ways to undermine cloud complexity and take advantage of geopolitical tensions for advanced attacks. They can also optimize their ransomware and phishing attack techniques by polishing them with generative AI.

2: Automated malware 

An AI like ChatGPT is excellent at accurately crunching numbers. According to Columbia Business School professor Oded Netzer, ChatGPT can already “write code quite well.”

While software like ChatGPT has some protections to prevent users from creating malicious code, experts can use clever techniques to bypass it and create malware. For example, one researcher was able to find a loophole and create a nearly undetectable complex data-theft executable. The executable had the sophistication of malware created by a state-sponsored threat actor*.

This could be the tip of the iceberg. Future AI-powered tools may allow developers with entry-level programming skills to create automated malware, like an advanced malicious bot. A malicious bot can steal data, infect networks, and attack systems with little to no human intervention.

3: Physical safety 

As more systems such as autonomous vehicles, manufacturing and construction equipment, and medical systems use AI, risks of artificial intelligence to physical safety can increase. For example, an AI-based true self-driving car that suffers a cyber security breach could result in risks to the physical safety of its passengers. Similarly, the dataset for maintenance tools at a construction site could be manipulated by an attacker into creating hazardous conditions.

AI privacy risks 

In what was an embarrassing bug for OpenAI CEO Sam Altman,ChatGPT leaked bits of chat history of other users. Although the bug was fixed, there are other possible privacy risks due to the vast amount of data that AI crunches. For example, a hacker who breaches an AI system could access different kinds of sensitive information.

An AI system designed for marketing, advertising, profiling, or surveillance could also threaten privacy in ways George Orwell couldn’t fathom. In some countries, AI-profiling technology is already helping states invade user privacy.

Stealing AI models 

There are some risks of AI model theft through network attacks, social engineering techniques, and vulnerability exploitation by threat actors such as state-sponsored agents, insider threats like corporate spies, and run-of-the-mill computer hackers. Stolen models can be manipulated and modified to assist attackers with different malicious activities, compounding artificial intelligence risks to society.  AI privacy risks

What is Machine Learning (ML)?

Machine learning (ML) is a branch of artificial intelligence (AI) and computer science that focuses on the using data and algorithms to enable AI to imitate the way that humans learn, gradually improving its accuracy.

How does machine learning work?

Machine learning is a subset of artificial intelligence that allows computers to learn from data without being explicitly programmed.

Data Collection: Gathering relevant data is the first step. This data can be anything from images, text, numbers, or a combination.

Data Preparation: The collected data is cleaned, organized, and transformed into a suitable format for the machine learning model.

Choosing an Algorithm: Selecting the right algorithm depends on the problem you’re trying to solve.

• Supervised Learning: The algorithm learns from labeled data (data with correct answers). Examples: classification (spam detection) and regression (predicting house prices).
• Unsupervised Learning: The algorithm finds patterns in unlabeled data. Examples: clustering (grouping similar data points) and association rule learning (finding relationships between items).
• Reinforcement Learning: The algorithm learns by interacting with an environment and receiving rewards or penalties. Examples: game playing, robotics.

Training the Model: The algorithm processes the prepared data to learn patterns and relationships. This process is called training.

Evaluation: The model’s performance is assessed on a separate dataset to see how well it generalizes to new data.

Prediction or Decision Making: Once trained and evaluated, the model can be used to make predictions or decisions on new data.

Machine learning methods

Supervised machine learning            

Supervised learning, also known as supervised machine learning, is defined by its use of labeled datasets to train algorithms to classify data or predict outcomes accurately. As input data is fed into the model, the model adjusts its weights until it has been fitted appropriately. This occurs as part of the cross validation process to ensure that the model avoids overfitting or underfitting. Supervised learning helps organizations solve a variety of real-world problems at scale, such as classifying spam in a separate folder from your inbox. Some methods used in supervised learning include neural networks, naïve bayes, linear regression, logistic regression, random forest, and support vector machine (SVM).

Unsupervised machine learning

Unsupervised learning, also known as unsupervised machine learning, uses machine learning algorithms to analyze and cluster unlabeled datasets (subsets called clusters). These algorithms discover hidden patterns or data groupings without the need for human intervention. This method’s ability to discover similarities and differences in information make it ideal for exploratory data analysis, cross-selling strategies, customer segmentation, and image and pattern recognition. It’s also used to reduce the number of features in a model through the process of dimensionality reduction. Principal component analysis (PCA) and singular value decomposition (SVD) are two common approaches for this. Other algorithms used in unsupervised learning include neural networks, k-means clustering, and probabilistic clustering methods.

Semi-supervised learning 

Semi-supervised learning offers a happy medium between supervised and unsupervised learning. During training, it uses a smaller labeled data set to guide classification and feature extraction from a larger, unlabeled data set. Semi-supervised learning can solve the problem of not having enough labeled data for a supervised learning algorithm. It also helps if it’s too costly to label enough data.
