Many users are concerned about their security, and some may argue that an ordinary database Is more secure than an online one. In most databases, the user can’t see or edit the management system of a database. A login and password is required to change the database or see the database. Lots of databases also have additional measures of making sure that it is secure, they have an encryption key added to the login interface, making it harder for people to get in. There are, however, many other threats to online databases.

There are many threats to an online database, such as SQL Injection, DOS (Denial of Service) and having weak authentication. SQL Injection is when a user gains access to edit secured data by “injecting” various SQL queries into a vulnerable SQL data channel. A Denial of Service Is when a perpetrator attacks the database, by sending packets of Information to the server, making It slower. The server responds, but doesn’t detect the user, so waits for a response. When this times out, the attacker will send another packet full of requests, until eventually.
