Parameterized Statements: Parameterized statements ensure that your inputs are handled safely.If your user enters something like 100 DROP TABLE Orders for their userID, the SQL statement becomes: SELECT * FROM Users WHERE userID = 105 DROP TABLE Orders īest practices for guarding against SQL injections The above example returns all the rows from the Users table and then deletes the Orders table. This will return all the rows from the Users table because OR “”=”” is always true.Įnjoying the article?

The above code gets the username and password of a user and selects data based on that. Sql = 'SELECT * FROM Users WHERE Name ='' + userName + '' AND Pass ='' + userPass + '''

Let’s look at another example: userName = getRequestString('username') This can be pretty dangerous if your table contains information like usernames and passwords. Since 1=1 is always true, the above statement will return all the rows of the Users table. If your user enters something like 100 OR 1=1 for their userID, the SQL statement looks like this: SELECT * FROM Users WHERE userID = 100 OR 1=1 Let’s look at some of the ways things can go wrong. The next line of code selects a user based on their id. In this example, we have a variable ( textuserID) that is fetched from the user input. textuserID = getRequestString('userID') textSQL = 'SELECT * FROM Users WHERE userID = ' + textuserID

SQL injections are fairly common strategies for attackers, so it’s important to learn how to defend against them. Attackers can bypass authentication, retrieve, add, or modify your database.

Attackers accomplish this by constantly creating traffic and sending requests.Ī common hacking technique that could destroy your database, SQL injections occur when you ask users for input, e.g., their id or username, and they enter an SQL statement instead. Though npm helps with app performance and developer productivity, you need to keep in mind the dependencies and security risks involved.ĭoS attacks either slow down your service or crash it completely. One of the largest open-source package ecosystems, npm is Node.js’s default package manager. Using default cookie names is a threat, as hackers can easily identify them. Your actions on a website are stored as cookies.

XSS attacks occur on input forms when they are not properly encoded or validated.ĬSRF attacks target changes in an application’s state requests leading to end users executing unnecessary actions on authenticated web applications. They can also redirect users to malicious websites. This section will briefly cover some of the popular attacks and threats, and explain how they work.Ĭross-site scripting lets hackers inject malicious client-side scripts into a viewed page, leading to data leaks. It’s important to know how hackers/attackers try to breach your Node.js app before you can start defending it. You’ll learn everything from sanitizing user inputs, encryption, hashing algorithms, and beyond.
