Introduction

Machine Learning in cyber security, a bliss or hit-and-miss?
No, you don’t need to wait for time to tell. We will reveal everything you need to know about boosting your cyber safety with machine learning. As innovation takes the front seat, cyber threats are evolving at a breakneck speed. With businesses and individuals relying more on interconnected systems, the risks of data breaches, ransomware attacks, and hacking incidents are growing exponentially. Traditional cybersecurity measures, though essential, often struggle to keep up with the sheer volume and complexity of these threats.
Enters machine learning—a game-changer in revolutionising the world of cybersecurity.
This blog explores how this cutting-edge technology is transforming the cybersecurity landscape, paving the way for a safer, and more secure digital future.

What is Machine Learning?

A seemingly complex concept, yet ML is widely used in versatile applications and across various domains. Technically speaking, Machine learning is a mix of computer science and artificial intelligence (AI). As the term depicts, machines learn from data and algorithms to make predictions and decisions. The learning process goes through trial and error based on the dynamic algorithm.

What is Cyber Security?

Cybersecurity is the practice of securing and protecting computers, network infrastructure, servers, and data from malicious attacks. Currently, cyber space is going through a challenging phase with sophisticated attacks bombarding the digital privacy and integrity of individuals and organisations.
Precisely speaking, cybersecurity encompasses a wide spectrum of various categories like - network security, application security, information security, operational security, disaster recovery, and end-user security.

How do ML & Cybersecurity complement each other?

As the global business environment swiftly adapts to the ongoing technological revolution, the risks of network intrusions and data breaches continue to rise.
Furthermore, the growing use of cloud services has significantly amplified data security concerns, with vast amounts of information being stored both on-premises and in the cloud. This is where machine learning and deep learning step in, offering solutions for identifying patterns and detecting threats.
To give you a clearer understanding of how machine learning complements cybersecurity, here we present a quick snapshot:

• Decision tree algorithm for threat detection & classification
• Dimensionality reduction algorithm for irrelevant data removing
• K as clustering for malware detection
• K as nearest neighbour classifier (kNN) for authentication in facial recognition
• Linear regression for predicting the outcomes of network security
• Logistic regression for the detection of fraud
• Naive Bayes algorithm for detecting unauthorised intrusions
• Random forest algorithm for classification of various types of phishing attacks
• Support Vector Machine (SVM) for classifying, detecting, and predicting blacklisted IP and port addresses

ML Applications in Cybersecurity

The advent of machine learning has significantly revolutionised the cybersecurity domain - simplifying and empowering every crucial aspect of maintaining its security and integrity. Let’s dig into some of the key contributions of machine learning in shaping the present and future of cybersecurity.

• Supervised ML in cybersecurity: Supervised machine learning in cybersecurity helps classify data and predict outcomes by training on labelled datasets. It’s used to identify network risks like scanning or spoofing and detect threats such as DDoS attacks. ML also helps to train models on both benign and malicious samples to predict whether new data poses a security risk.
• Reinforcement ML in cybersecurity: Very similar to supervised machine learning, this form of machine learning trains the algorithm through trial and error, instead of using sample data. Reinforcement machine learning is proactively used for identifying and responding to real-time attacks, intrusion detections, and defending distributed denial of service (DDoS).
• Unsupervised ML in cybersecurity: This type of machine learning is widely used for identifying hidden patterns and grouping minus any human intervention. The process is done by scanning through datasets to identify patterns and is commonly used for deep learning. This form of machine learning is used to execute various cybersecurity tasks - such as the detection of unusual behaviour, identification of new attack patterns, and mitigation of zero-day risks.
• Semi-supervised ML in cybersecurity: This is a collaborative approach involving both supervised and unsupervised ML that involves pulling small-labelled data sets from large unlabelled datasets. It involves precise classification, feature extraction, and mitigation of various risks like identification of malicious and benign bots, malware, and ransomware detection.
