St Metrics in the development of Java Library: How to ensure security and reliability
With the widespread application of the Java library in software development, developers need to pay attention to security and reliability.You can use ST (Security, Safety, and TrustWorld) indicators to ensure that the developed libraries meet these requirements.This article will introduce the use of ST Metrics in the development of the Java class library and provide some Java code examples.
一、ST Metrics
ST Metrics is an indicator for assessing software security, security and credibility.Developers can use these indicators to ensure the quality and reliability of code and class libraries.Here are several commonly used St Metrics indicators:
1. Security: The ability to evaluate the category library in protecting the system to avoid malicious attacks and threats.For example, you can use the following indicators to evaluate the safety of the class library:
-D quantity of security vulnerabilities: Analysis tools and dynamic vulnerability scanners through static code analysis tools and dynamic vulnerabilities.You can use the standards such as OWASP TOP 10 to identify common vulnerabilities.
-Clery and authentication: Whether the appropriate encryption algorithm and authentication mechanism are used in the assessment class library to protect sensitive data.
2. SafeTy: It is used to evaluate the stability and robustness of the class library during runtime.Here are some common reliability indicators:
-Cleway: Evaluate whether the abnormality is dealt with reasonably in the class library, for example, capture abnormalities and perform appropriate error treatment.
-Datalog leakage: By using memory analysis tools, there is a problem with memory leakage to ensure that the class library can correctly release resources.
3. Trustworthice: used to evaluate the credibility and reliability of the class library.The following are several common credibility indicators:
-Code coverage: use code coverage tool to evaluate the code coverage of the class library to ensure that the unit test covers the maximum code.
-Prown support: evaluate the community activity and feedback of the class library.More active communities usually mean higher reliability and credibility.
Second, the practice of ensuring the safety and reliability of class libraries
1. Use Safety Development Life Cycle (SDLC): Incorporate ST Metrics into a safe development life cycle to ensure that every stage of development pays attention to security and reliability.For example, consider security needs in the demand analysis phase, carry out security design in the design stage, and perform code review and security testing in the code writing stage.
2. Application of best practice: In the development of the class library, follow the best security programming practice, such as using secure API, input verification and output coding to reduce the risk of security vulnerabilities.
3. Use appropriate tools and libraries: Use the appropriate static code analysis tools, dynamic vulnerabilities scanners and other security tools to assist the safety and reliability of the class library.
The following is a simple Java code example to demonstrate how to enable input verification in the class library to ensure security:
public class User {
private String username;
private String password;
public User(String username, String password) {
if (isValidUsername(username)) {
this.username = username;
} else {
throw new IllegalArgumentException("Invalid username");
}
if (isValidPassword(password)) {
this.password = password;
} else {
throw new IllegalArgumentException("Invalid password");
}
}
private boolean isValidUsername(String username) {
// Implement the verification logic of custom user name
}
private boolean isValidPassword(String password) {
// Implement the customized password verification logic
}
// Other code and methods
}
In the above examples, the User class executes input verification in the constructor to ensure that only the user name and password that only meets the requirements is accepted.By achieving custom user name and password verification logic, malicious users can prevent malicious users from input invalid or insecure inputs.
Summarize
In the development of the Java class library, it is crucial to ensure safety and reliability.ST Metrics provides a set of indicators to help developers evaluate the safety, reliability and credibility of the class library.By following the safety development life cycle and the adoption of the best practice, developers can create high -quality, safe, and reliable Java class libraries.
