Data integration unifies information from across different sources, such as databases, applications, and the cloud, and creates a consistent format for analysis and decision-making. In cybersecurity, it is essential to eliminate silos and inconsistencies and make information more accessible.
This process goes beyond data ingestion to include its transformation, analysis and visualisation, and also supports business intelligence (BI) tools. It is critical to identify threats and vulnerabilities in real time, strengthening security and responsiveness to threats.
Processes bring together data from multiple sources
1
Data identification and extraction - The first step is to identify all relevant data sources for the integration, which can include internal databases, spreadsheets, legacy systems, cloud services, external APIs and more. Next, the data is extracted using specific extraction tools, which can range from database queries to APIs.
2
Data mapping and transformation - It is essential to create a mapping schema that defines how data from different systems should be aligned and correlated. The data is then transformed into a common and consistent format through cleansing, enrichment and normalisation.
3
Data quality validation - A critical stage in verifying the accuracy, integrity and consistency of information. At this stage, errors, inconsistencies or format problems are detected and corrected using quality control processes. Only valid and error-free data can be considered useful.
4
Loading and synchronising data - Data is loaded into the target system, such as a data warehouse or other designated target. The data is then synchronised to ensure that the information is always up to date and ready for real-time use.
5
Data governance, security and analytics - Data integration requires governance practices to ensure regulatory compliance and to protect privacy and security. At the same time, data is made available for analysis through business intelligence tools to support business decisions and strategies.
Data integration systems include many of the following tools:
