Top 3 Tips for Ensuring Security During Java Development

This article reviews three of the best practices developers can use to code with Java safely and securely.

Even though Java has been around since the 1990s, it continues to be a popular programming language in the development ecosystem. It is because Java has long demonstrated its value as an A-grade resource that allows developers to effectively deal with the many challenges associated with other prevalent languages and enable the development of high-quality solutions. 

Java continues to be celebrated as a terrific programming language that delivers ace levels of security. However, that also does not mean that programmers can take protection for granted. To put it simply, ensuring the safety of your Java app should be one of the top priorities for any company, for, without it, the business is likely to suffer the wrath of consumers' distrust! So, to help you avoid that situation and continue to deliver Java apps with top-notch quality and safety, we have listed some of the best practices that one would do well to adopt and integrate into their Java web application development project.

Safeguard Against Injection Attacks

SQL injection, easily one of the biggest vulnerabilities in this context, can allow nefarious elements to gain access to sensitive data. It happens when an attacker is successfully able to intercept an app's queries to its database and use it to access user data, which can then be leveraged for any illegal purposes. However, this can be prevented, of course; you can ensure attackers are unable to use SQL injection attacks against your app by parameterizing queries. It, in turn, can be done by making use of a prepared statement. Ideally, developers should use only this method to build queries. Given below is a sample code snippet to help you understand this better:

Java
 




x
10


 
1
public void prepStatmentExample(String parameter) throws SQLException {
2
   Connection connection = DriverManager.getConnection(DB_URL, USER, PASS);
3
   String query = "SELECT * FROM USERS WHERE lastname = ?";
4
   PreparedStatement statement = connection.prepareStatement(query);
5
   statement.setString(1, parameter);
6
   System.out.println(statement);
7
   ResultSet result = statement.executeQuery();
8
 
          
9
   printResult(result);
10
}



Vet External Libraries

It is one of the most constructive steps any Java development team must undertake to make sure that the code that they ship does not include a vulnerability, that can destroy the quality as well as the reputation of the web app. Additionally, it also allows developers to identify bugs, performance issues, and more

Deal with Data with Abundant Caution

Every web app typically contains an abundance of sensitive data, such as customers' bank account details, and more. Hence, developers must be abundantly cautious when it comes to the data; you can start with evaluating if you need the sensitive data the app is asking for. And don't forget to purge the domain entities' toString() methods.

Java web application development, when done with a specialized focus on security, can empower not only customers but also the companies. And with this, it becomes that much easier to take your business to the next level.
