Machine Learning for Cyber Security
In the world of cyber security, there are two main types of attack detection techniques: signature-based cyber security and anomaly-based cyber security. They share a common application of machine learning methods. Signatures that accurately detect malicious code’s code and behavior are being built with the help of machine learning techniques. Signature-detection techniques, such as Network-based Signature Generation (NSG), Length-based Signature Generation (LSEG), and F-Sign, are designed to operate automatically.
To detect and slow the spread of worms, the LSEG algorithm zeroes in on those that employ a buffer overflow attack, while the F-Sign retrieves a signature based on the code of a specific worm. Other algorithms, like Semantic Aware’s, are made to create malware signatures based on the traffic they cause on a network. When there is abnormal traffic, these technologies are able to detect malicious activity.
Machine Learning Techniques
In order to spot cyberattacks, anomaly-based techniques create a smart model that defines typical and anomalous network activity. Unsupervised, semi-supervised, and supervised machine learning techniques are likely used in such approaches. K-means, fuzzy c-means, QT, and support vector machines (SVM) are only some of the algorithms adapted for usage in clustering approaches for unsupervised learning. In many cases, it is necessary to decide whether or not a particular cluster of network traffic established utilizing the ways should be marked as harmful. The vast majority of unsupervised algorithms rely on the majority rule, which states that only the largest clusters should be treated as typical. This means that typical network occurrences show no signs of compromise. It takes a human eye to determine whether or not a cluster should be flagged as unusual.
For the supervised machine learning methods, just one iteration of learning is necessary to construct the traffic model. The training takes place in a non-real-time environment using simulated traffic data. Some supervised machine learning models for network intrusion detection use anomaly detection to adapt different machine learning techniques. Most approaches consist of three stages:
- Attack Detection
- Feature Vector Extraction
- Algorithm Learning
The network operates in a very unique way; unlike most others, it can read data files of varying types, extract user information, and feed it to machine learning models. Anomalies in data are flagged by ml engines, which also provide the predicted attack’s monitor if the forecast from the machine learning model is negative. If the prediction is positive, the data is accepted as normal. They pass the data normally if it is normal. They would first issue a warning, then halt data transfer, and finally protect the systems from whatever anomaly had been detected.
NetworkFort as a Cyber security solution
NetworkFort identifies and mitigates cyber security threats including DDoS attacks, exfiltration attacks, and DNS attacks, among others. You can prevent these kind of cyber attacks in one fell swoop if a machine-learning engine is built into your network’s defenses.
NetworkFort identifies and stop such assaults since we monitor and analyse all network traffic. We uses traffic analysis for the detection of attacks by adding an alert about the suspicious log.
