Data source definition
A data source is any location where all of the data that users gather comes from. It can be in the form of a database, XML file, a flat file, web services, cloud storage, data warehouses, or any other format that the system can read. Every data source can have unique characteristics, like the type of data it keeps, how it is structured, and how the user may access it. Data sources play a crucial role in data management because they make it possible for organizations to gather, store, and recover information quickly and effectively. They are also essential to business intelligence and data analytics since they deliver the unprocessed data required to produce insights and make acceptable choices. However, it often attracts hackers, as it includes personal and confidential information about users, such as login credentials, financial data, and bank accounts.
Preventing data source hacking
- Utilize strong and unique passwords. The passwords should consist of letters, numbers, and symbols. Therefore, hackers won’t be able to guess them easily.
- Encrypt data. While users share the data online, encryption methods like SSL, HTTPS, and TLS are crucial for data safety.
- Limit data access. Always grant access to data only to users who necessarily need it for work. Provide unique authorization methods for those users, such as passwords and two-factor authentication.
- Use two-factor authentication. This technique adds an extra layer of protection as it requires another form of identification. The second verification method can be a code sent via SMS or even a fingerprint or a face scan.
- Update the software. Ensuring that all software, such as web browsers, operating systems, and antivirus software, are up to date increases the security layer that prevents hackers from exploiting vulnerabilities.
- Avoid phishing emails. Don’t open suspicious links or other attachments from unknown senders because phishing scams will trick you into revealing your confidential data.
