Code Injection

 

Code Injection

 Definition:

Code injection occurs when an attacker exploits a vulnerability in a system by injecting malicious code into a vulnerable program. This manipulation allows the attacker to alter the program’s intended execution, often resulting in severe consequences such as the spread of computer viruses or worms.

Types of Code Injection:

1. Cross-site Scripting (XSS): Learn more
2. SQL Injection: Learn more
3. LDAP Injection
4. Carriage Return-Line Feed Injection (CRLF)
5. SMTP Injection
6. Command Injection

How to Protect Against Code Injection:

1. Strong Coding Practices:
   Ensure secure coding techniques are followed during application development. Validate and sanitize all user inputs to prevent malicious code from being processed.

2. Comprehensive Security Testing:
   Perform thorough security testing of applications or websites before deployment to identify and fix potential vulnerabilities.

3. Use Trusted and Secure Applications:
   Always use authorized websites and verified secure applications to minimize risks.

4. Implement Least Privilege Access:
   Grant users only the minimum access necessary for their roles. For instance, if an employee does not require internet access for their work, restrict their access to prevent unnecessary exposure to risks.
