5 difficulties in anomaly detection

Anomaly detection, also known as outlier detection or outlier recognition, is an algorithm and technique used to identify anomalies or unusual patterns in a data set. Anomaly detection is an important branch of data mining and machine learning, which is widely used in many industries and fields. Anomaly detection, also known asoutlier detection, has applications in…

The importance of anomaly detection in data analysis

Anomaly detection methods are effective in identifying outliers or unusual patterns in data, which can be crucial for fraud detection and security. These techniques can enhance operational efficiency by flagging issues early, allowing organisations to address problems before they escalate. Anomaly detection is widely applicable across various domains, including finance, healthcare, and manufacturing, making it…

Is anomaly detection supervised or unsupervised?

Anomaly detection can be approached using both supervised and unsupervised methods, depending on whether you have labelled data. Unsupervised methods are often used when labelled examples are not available, while supervised techniques are applied when such data is present. Supervised anomaly detection Supervised anomaly detectioninvolves training a model on a dataset with labelled examples of…

Exploring packet filters for anomaly detection in network security

Packet filters can analyse incoming and outgoing network packets to identify unusual patterns that may indicate security threats. Different types of packet filtering technologies, such as stateful and stateless filters, have varying capabilities for detecting anomalies based on traffic behavior. Combining packet filtering with other security tools enhances an organisation’s ability to detect and respond…

What is network anomaly detection?

Network anomaly detection involves identifying unusual patterns or behaviours within a network that deviate from the expected norm. It plays a crucial role in maintaining network security and performance by detecting potential threats and issues early. Network anomaly detectionis a critical aspect of network security and performance management. It involves the continuous monitoring of network…

What is a host-based intrusion detection system?

A host-based intrusion detection system is a security software that monitors and analyses events occurring within a computer or server to detect suspicious activities indicative of a security breach. The key components of a HIDS include event generators that collect data, event analysers that detect anomalies through rule-based or statistical methods, and response mechanisms that…
