Before you connect to the MySQL databases, take a look at SSL-related content in the MySQL official document.

So let’s take a look at how to make SSL connections. Encrypted query information thanks to SSL connection Learn MySQL SSL Connections 1. You're not going to see the user executes the application information because it's now encrypted. After you have established an SSL link, try using WireShark again. Exposed query information that users run on a general connectionĮven when connecting to an SSL database, users send and receive information between their device and the database is encrypted. A situation as simple as this can lead to an attack in which personal information is leaked, or a middle man falsifies queries. The image below shows an example where a user executes the SELECT * FROM STAFF query, and easily found by any third party with the help of Wireshark. Try analyzing the query performed through a packet analysis program, like the open source program WireShark, and you see the information passed between the user and the database. Let’s assume we run a simple SELECT * FROM STAFF query that shows table data containing personal information of customers while we have an unprotected connection. Let’s think about a particular situation in which SSL is not used, and the database security is vulnerable. Without an encrypted connection (SSL) to the databases, query statements, or data results exchanged between the user and the database can be exposed to a middle man. Similar to websites, SSL features are also useful when connecting to Databases. For example, the TLS/SSL protocol is an authentication process based on public keys and allows applications to protect their users’ privacy by providing essential support for SSL functionality.ĭoes the database require SSL capabilities? However, adding a security authentication procedure to the connection between the user and the server can help prevent a 3rd party attack.
This act is defined as a Man in the Middle (MITM) attack. But what if someone intercepted sensitive data such as credit card numbers, account passwords, and other private information? Because the information is not encrypted, third parties may steal it and exploit it. It wouldn’t be a problem if it weren’t important information. So third parties may access that communication through the web server and pick off your information. Accessing a website that does not support SSL, your communication (sending and receiving information) with the site you’re accessing is not encrypted. You can still use the site after viewing the warning if you click the little Continue button, but if you choose to do so, then you will have no security. This error commonly occurs when HTTPS (SSL) is not applied to a website that’s accessed through Chrome. Even if you never heard of the term SSL, I think everyone has run into this error page at least once: Website warning that SSL is not applied While surfing the web, sometimes you might run across the error message “ Your connection is not private” when HTTPS is not set up locally. Why do we need a Secure Sockets Layer (SSL)? Today, I’d like to suggest some steps to increase the security of a database: How to connect to an SSL-based database using JDBC. Given these backgrounds, database security solutions are no longer an option but a necessity. So there have been growing calls for companies to ensure strict data security. There have been dozens of data leakage incidents that made the entire nation uneasy in the past, like the famous situations with Facebook and Amazon. Security issues that occur in databases storing particularly sensitive personal information have a huge impact because they significantly violate the privacy of individuals. Difficulty in controlling access to databases: Issues that need to be given and managed by different users, such as modifying, adding, and deleting data depending on user needs.Data leakage and malicious change: When access information is leaked, data in the database is leaked out or tampered with for malicious purposes.Database Access Information Leaks: Exposure of accessible information such as usernames, passwords, and other sensitive information allows access to unauthorized third-parties.Here is an overlook on the issues involved: Database Security Issues But of course, there are multiple security issues in every database used. Why is Security important for a database?Īlmost every company, from start-ups to large corporations, uses databases to collect and store important information.
