Top 10 Anomaly Detection Software for Secured Enterprise

Top 10 Anomaly Detection Software for Secured Enterprise

Anomaly detection involves identifying data points and patterns deviating from an established hypothesis. This practice, enduring through time, holds vital importance in contemporary contexts. Detecting anomalies is imperative as they often signify crucial information, including a pending or ongoing security breach, hardware or software malfunctions, or shifts in customer demands. These anomalies signal various challenges necessitating immediate attention.

Anomaly detection can be applied to both single-series and multi-series data. Multi-series data comprises multiple independent sequences of events. For instance, in sales data for multiple stores, each store’s sales can be individually analyzed by a single model using the store identifier.

How does Anamoly Detection Work?

Anomaly detection is essential in business settings as it presents accurate and imperative means of detecting unusual cybersecurity and enterprise IT incidents. Utilizing AI models characterizing system behavior and data analytics enables organizations to compare real-world data against predicted values, thus providing critical insights.

When the difference between predicted and actual data measurements exceeds a prescribed threshold, actual data is considered an outlier or anomaly. This identification helps analysts and decision-makers:

  • Understand the causes of an anomaly
  • Forecast future trends

No model can fully characterize the behavior of complex real-world systems. For example, network traffic to servers is a function of hardware and software systems performance that route global traffic, and the preferences and intents of a heterogeneous set of users.

However, data-driven organizations depend on concrete information from real-world interactions between technologies and end-users. This information, usually collected by monitoring techniques such as synthetic monitoring and real-user monitoring, is used to formulate data models or establish a generally acceptable basis and abide by factors and constraints.

Overcoming Anomaly Detection Challenges

Anomaly detection faces several challenges, such as distinguishing noise from genuine outliers. However, the most complex task is modeling normal behavior to provide the appropriate context for identifying anomalies.

Modeling Normal Behavior

Time series data offers the essential context for normal behavior, critical for detecting anomalies. Without this context, identifying outliers becomes difficult, especially in large, complex systems like environmental trends and traffic fluctuations. Predictive data quality addresses this challenge by facilitating unsupervised anomaly detection at the organizational level. This method involves creating rough statistical models by compressing raw data into significantly smaller chunks, allowing for benchmarking and baselining datasets over time.

Additionally, approved variance in modeling normal behavior enhances the precision of anomaly detection.

Noise and Poor Data Quality

In specific use cases, such as healthcare, the detection rules for outliers are stringent, and even minor changes can be critical. Therefore, managing noise and ensuring high data quality is vital for distinguishing outliers from normal records. Failing to do so can undermine the effectiveness of anomaly detection.

Streaming Data Volume

Large volumes of streaming data can impact system processing speeds. Scalable predictive data quality solutions help detect drifts and outliers in real-time, providing early warnings through machine learning-based algorithms.

In-Depth Data Understanding

Some datasets include specific values not intended for outlier detection or data quality assessments. Understanding these extreme values can be challenging, as time-series context alone is often insufficient. Data intelligence aids in accurately comprehending and utilizing enterprise-level data. By connecting insights, data, and algorithms, businesses can thoroughly understand their data, enabling more accurate identification of anomalies.

Types of Anomalies

Global Anomalies (Point Anomalies)

A global anomaly is a data point that is significantly higher or lower than the average. For instance, if the average credit card bill is $2,000, a bill of $10,000 would be considered a global anomaly.

Contextual Anomalies

Contextual anomalies depend on the specific context in which they occur. For example, credit card bills may vary seasonally, such as higher spending during holidays. While these spikes might appear anomalous when viewed in aggregate, they are expected within the seasonal context.

Collective Anomalies

Collective anomalies refer to a set of data points that, when considered individually, may not appear unusual but collectively indicate an anomaly over time. For example, a credit card bill increasing from $2,000 to $3,000 for one month might not raise concern. However, if it stays at $3,000 for several months, it becomes a detectable anomaly. These are often identified using “rolling average” data, which smooths out a time series to highlight trends and patterns.

Anomaly Detection in Artificial Intelligence

In the evolving field of Artificial Intelligence, anomaly detection continues to gain prominence as AI capabilities advance. Anomaly detection in AI involves analyzing:

  • Nature of Data Instances and Observations: This includes incidents, sensor data, alerts, and metrics data.
  • Nature of Deviation: This encompasses contextual (related to multiple metrics or decision classes), point-wise (related to a single metric or decision category), behavioral (not assignable to specific quantitative metrics), and collective (related to all data instances across all metrics or decision classes).
  • Learning Methodology: This includes supervised learning (with available ground truth), unsupervised learning (without available ground truth, where models identify patterns within datasets for classification), and semi-supervised learning (which incorporates some ground truth).
  • Output Thresholds, Scores, and Classification Labels: These are based on business context and aim to quantify the business impact of acting on the outcomes of an anomaly detection model.

AI-based anomaly detection is a crucial component of intrusion prevention systems. These systems prevent unauthorized network traffic, login attempts, and data transfers by:

  1. Evaluating network requests based on a set of metrics.
  2. Computing expected behavior.
  3. Comparing expected behavior with the actual nature of the network request.
  4. Classifying the request as unauthorized if it significantly deviates from expected behavior, thus preventing its execution.

Strengthening anomaly detection algorithms and improving data quality initiatives necessitates the development of a robust data governance program. By prioritizing data governance, organizations can enhance anomaly detection capabilities and ensure the integrity of their data.
