Most Common Coding Errors

No matter what language is used when coding, there are common mistakes that can lead to big problems, if not dealt with early. These coding errors can cause serious breaches in security and unstable platforms, which costs time, effort and money to repair.

Recently, even big companies like Sony have suffered from error correction requires significant programming to protect their online customers private information. A small error in the coding required removal of part of the PlayStation Network. Users were asked to reset their passwords and cancel their credit cards as a result of hackers access to an exploitable vulnerability.

Each language has its own set of parameters and issues, but coding errors are common, for one reason – everyone has them. The trick is to recognize and address them early in the process of programming.

Some of the most common types of coding errors in the main languages ​​of programming:

VISUAL BASIC

The three most common coding errors in Visual Basic are syntax, run-time and logic errors.

Syntax: These errors involve typographical and grammar errors made when writing code. Repairs are relatively simple can be remedied immediately.

Run-time: After the code is compiled and ready to go, these errors appear when the code refuses to run. In this case, the wrong code needs to be identified and corrected. The whole process is then executed and tested again before going live.

C & C++

Coding errors in C and C++ not only affect the initial product, but are inherited by subsequent coders. The most common errors are made in the following areas:

• Memory and resource management
• Program data management
• Buffer overflows
• Concurrency violations
• Vulnerable coding practices
• Platform support
• Long-term maintenance support

Java

In addition to concurrency violations and resource management, Java presents a set of unique challenges to the coder. Areas of concern include:

• Web application weaknesses
• Unconfirmed user input
• Device-specific coding practices
• JSP interactions
• Invalid object references
• Improper collection usage

Another serious, yet common coding error involving cross-site scripting, and permissions incorrectly, which can lead to insider data breaches. Cross-site scripting is the result of a Web page may involve compromises and attacks against the web server itself. as another common problem is SQL injection. SQL injection is the result of not following key best practice in the management of user input: Always assume the data entry is hostile, to define specific models that are safe, and not allow entry to process if it corresponds to one of the reasons security.

System downtime and security vulnerabilities are the inevitable results of code errors, but they are not the only negative side effects. Erroneous output, loss of reputation, and / or loss of customer traffic are all likely possibilities.

Better security measures should start with correcting the most common errors in coding. Follow the best practices outlined in the language to keep things clean and safe. Try to keep things simple, the more complex you get, the more chances to make mistakes. More important, however, stay educated and updated information on errors and safety hazards that lie ahead.
