Boosting Securities Ops with AI: A Practical Intelligent Operations Platform

Intelligent Operations Platform Overview

The platform adopts a “1+3” architecture: a central operations data bus plus three sub‑platforms (integrated ops, big‑data, and algorithm services). It is organized into five vertical layers:

Discovery Layer : real‑time collection of topology and status from applications, storage, network devices, and operating systems via automatic discovery or configured rules.

Interface Layer : aggregation of heterogeneous monitoring data (out‑of‑band management, cloud‑control platforms, ITIL tools) using a Kafka message bus for decoupled, high‑throughput ingestion.

Data Layer : normalized storage in a CMDB, a knowledge base, and a time‑series store (ElasticSearch) to support fast distributed queries.

Analysis Layer : AI algorithms implemented in Python on Apache Spark; data exchange via JSON. Provides semantic analysis, graph algorithms, and traditional ETL services.

Scenario Layer : maps concrete use cases (network‑attack detection, root‑cause analysis, capacity prediction) to the platform. Prioritization follows a four‑quadrant method.

Scenario Implementations

1. Root‑Cause Analysis

Problem : Massive correlated alerts make manual diagnosis infeasible.

Algorithm : A ranking algorithm inspired by search‑engine sorting combines three sub‑algorithms:

White‑box : evaluates alert propagation order based on system topology. Scores are derived from a pre‑computed “impact‑score” table for each device type.

Black‑box : a convolutional neural network (CNN) learns correlations between concurrent alerts and root causes from synthetic training data generated by grouping alerts whose first‑occurrence interval ≤ 2× monitoring interval.

Change‑experience : assigns higher scores to components with recent configuration changes (ITIL‑based).

Y = Σ (Wi × Xi)   // Wi = weight of sub‑algorithm i, Xi = score from sub‑algorithm i

Weights (W1, W2, W3) are tuned by a genetic algorithm that searches the space [0,1] with 0.01 granularity to maximize hit‑rate on a validation set. Production tests show a >90% root‑cause hit rate. The final ranking UI displays weighted scores and ranked candidates.

2. Intelligent Knowledge Base

Goal : Consolidate system documentation and troubleshooting solutions, and enable natural‑language Q&A.

Data Pipeline :

Web‑crawled generic IT knowledge (Microsoft, Apache, Red Hat, etc.) and industry‑specific operational knowledge (~10 k entries) are collected.

SVM classifiers filter and clean the raw crawl, reducing ~300 k raw records to 131 k high‑quality entries.

ElasticSearch stores the indexed knowledge base.

Model : An LSTM‑based backend provides answer generation; a graph‑based reasoning model enriches semantic understanding. Feature extraction includes question words, core semantics, named entities, and part‑of‑speech tags.

In production the knowledge base contains >140 k entries. User queries achieve an 87% hit rate within three searches and an average satisfaction score of 4.27/5.

3. Capacity Prediction

Scope : Forecast key performance indicators (QPS, CPU utilization, memory usage) for an online trading system.

Method : Holt‑Winters triple exponential smoothing applied to minute‑level historical metrics. The first two‑thirds of the time series are used for training; the remaining third serves as a test set. Model accuracy is measured by Mean Absolute Percentage Error (MAPE).

Results:

QPS prediction MAPE ≈ 2.24%

CPU utilization prediction MAPE ≈ 2.38%

Memory usage prediction MAPE ≈ 2.18%

When forecast confidence intervals exceed predefined thresholds, tiered alerts are generated (yellow for early warning, red for critical), enabling proactive scaling.

Evaluation and Conclusions

The integrated AI‑big‑data platform substantially improves operational efficiency in the securities domain. Quantitative outcomes include:

Root‑cause analysis hit rate > 90% with a median ranking of the true cause within the top‑3 results.

Intelligent knowledge base delivers an 87% hit probability within three queries and a user satisfaction score of 4.27/5.

Capacity forecasting achieves MAPE ≈ 2% across key metrics, enabling reliable pre‑emptive scaling.

Remaining challenges are handling unrelated concurrent alerts in root‑cause analysis and ensuring comprehensive, high‑quality data for the knowledge base.
