Study Notes

Software Security Practices Quiz Overview

Multiple-choice quiz focused on software security principles, practices, and risks.
Questions test knowledge on the goals of software security, practices for accountability, and phases of the Software Development Lifecycle (SDLC).

Key Facts and Concepts

Primary Goal of Software Security:
- Maintaining confidentiality, integrity, and availability (CIA) of information resources.
Accountability in Development:
- Clearly defining roles and responsibilities is crucial for accountability in a software development team.
Integration of Security in SDLC:
- Secure SDLC activities should be integrated into each phase to ensure software security.
Importance of Secure Coding Standards:
- Establishing secure coding standards helps minimize the introduction of vulnerabilities.
Reusable Object Library Benefits:
- Creating and maintaining a reusable object library ensures the consistent use of secure components across projects and enhances development speed.
Design Phase Security Flaws:
- The failure to identify security requirements upfront can introduce significant security flaws during the design phase.
Server-Side Validation:
- Validating data on the server side ensures data modifications are checked, providing protection against various attacks.
Principle of Least Privilege:
- Users should only have the minimum level of access necessary to perform their specific tasks to enhance security.
Preventing SQL Injection Attacks:
- Parameterized statements are highly effective in preventing SQL injection by binding input parameters.
Mitigating Denial of Service (DoS) Attacks:
- Employing firewalls and intrusion detection/prevention systems is recommended to protect against DoS attacks.
Output Encoding Against XSS Attacks:
- Escaping or encoding output helps prevent the execution of injected code, thus mitigating Cross-Site Scripting (XSS) risks.
Secure Password Storage Practices:
- Passwords should be hashed using a strong cryptographic algorithm and salted to ensure security.
Prepared Statements in SQL:
- Using prepared statements binds parameters in SQL queries, effectively preventing SQL injection.
Secure Authentication Management:
- Centralized authentication systems enhance security by managing how credentials are stored and authenticated.
Error Handling Security Considerations:
- Avoid disclosing sensitive information in error messages to maintain security.
Unauthorized Data Modification Prevention:
- Server-side validation and access controls are essential to protecting against unauthorized data modifications.
Mitigating Session Hijacking Risk:
- Ensuring session IDs are sufficiently random and secure can protect against session hijacking attacks.
Importance of Network Security Measures:
- Implementing firewalls helps prevent unauthorized access and provides protection against DoS attacks.
