Furthermore, simple passwords are much easier for an attacker to crack offline should they manage to steal MySQL users’ password hashes. This means that the database user account can be brute-forced either remotely or locally (requires to already have access to the server). Many administrators, choose very easily guessable passwords for their own convenience, or forget to change passwords when the server moves into a production environment. A strong password should be longer than 12-15 characters and should be a combination of alphanumeric and special characters and ideally, it should not contain words you can find in a dictionary (e.g. Mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server mysql-server-5.7 mysql-server-core-5.7Ġ to upgrade, 9 to newly install, 0 to remove and 253 not to upgrade.Īfter this operation, 160 MB of additional disk space will be used.ĭo you want to continue? Y MySQL Setup – Root accountĭuring the initial setup, we are being prompted to set a password for the MySQL’s root account. The following NEW packages will be installed Mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7 mysql-server-core-5.7 The following additional packages will be installed: The installer will search for the packages and dependencies that need to be installed and then we will be prompted to confirm that we want to proceed with the installation of those packages. Now that our package lists are updated, we can proceed with the installation of the latest version of MySQL server by running the following command. We will proceed with the second option, since it is always better to run the latest version of a software.īefore installing any software, we need to make sure that our system has the latest package lists from its repositories, otherwise, this might result in installing outdated software. We can either do a version-specific installation or automatically install the latest version that is available for our distribution. MySQL server can be installed in two ways. ![]() ![]() We have also edited our hosts file to point ‘’ to the IP address of our test machine. In this series, we will focus on SQL Security, showing how to create a more secure environment for MySQL server, which is currently the second most popular database management system (DBMS), in order to prevent common attacks, as well as to mitigate the attack vector of other vulnerabilities.įor the purposes of this article we have setup a machine running Ubuntu 16.04 LTS (Xenial Xerus) and MySQL 5.7. However, misconfiguration of the database server itself can also lead to unauthorized access or escalation of privilege which is granted via other vulnerabilities like the SQL Injection. In SQL injection, the database server is not directly exposed to the attacker since an attacker would exploit vulnerabilities that arise as a result of poor coding practices in the frontend or backend of web applications. To such an extent, SQL security is crucial since securing databases and their content is key.įor the past 15 years, SQL injection has been among the most common and dangerous attacks on web applications. Legislation around the world is very strict when it comes to data privacy, so much so, that substantial fines may be incurred by organizations suffering a data breach. ![]() Data breaches, commonly expose data containing personally identifiable information such as names, usernames, passwords, email addresses, credit card numbers, health records as well as other confidential documents such as trade secrets or commercially sensitive information. ![]() As applications continue to grow, so is the amount of data that is being stored into their databases, which is the main reason why they are the number one target of attackers–databases frequently contain information that is useful or desirable to an attacker. Almost every software program relies on some sort of database to store its data. Databases can be found in everything from desktop applications, web applications, corporate servers to smartphones and other devices.
