What Are the Mitigation for All Owasp Top 10 Vulnerabilities?
With the growing number of applications and the sophistication of hackers, organizations must stay vigilant on security vulnerabilities. It’s also important to know how to mitigate them.
To this end, the Open Web Application Security Project (OWASP) helps organizations develop, operate, and maintain secure and trusted applications. Their projects, tools, chapters, and forums can help one improve the security of applications.
For example, they have a top ten list of mobile application security risks aimed at helping mobile app developers produce secure code.
They also have the top ten web application security risks that one can mitigate.
They include:
- Injection
These include SQL, LDAP, and code injection. These attacks allow manipulated or untrusted queries or commands to be executed on the app.
Mitigation
Use a vetted framework or library that prevents these attacks from happening. Input validation, use a safe API, and ensure the app runs with minimum privileges.
- Broken Authentication and Session Management
It allows the attacker to bypass authentication on the web application.
Mitigation
Enable encryption on requests with sensitive data and have a strong password policy for users.
- Sensitive Data Exposure
Failure to protect sensitive data can provide hackers with an opportunity to steal or modify the data for identity theft, card fraud, etc.
Mitigation
Encrypt data while in transit or at rest, use up to date security certificates, and encrypt stored passwords.
- XML External Entities (XXE)
Attackers exploit vulnerable XML processors using vulnerable code or by adding hostile content to XML documents.
Mitigation
Upgrade or patch all XML libraries and processors used by the application. Use less complex data formats, and don’t serialize sensitive data.
- Broken Access Control
Not enforcing restrictions on authenticated users can allow attackers to access unauthorized data.
Mitigation
Implement a robust access control, log access control failures, and invalidate JSON Web Tokens (JWT) after logout.
- Security Misconfiguration
Attackers access the system by exploiting insecure or incomplete configurations, unprotected files, unpatched flaws, etc.
Mitigation
Securely configure all frameworks, libraries, operating systems, and apps. You should also review and update all security updates, patches, and notes.
- Cross-Site Scripting XSS
XSS allows an attacker to execute code on the victim’s browser, hijack user sessions, redirect users to malicious sites, or deface web sites.
Mitigation
Use frameworks that escape XSS by design automatically and escape untrusted HTTP requests. Apply context-sensitive encoding techniques when modifying a client-side document against DOM XSS.
- Insecure Deserialization
It leads to remote code execution. Attackers use it for injection attacks, replay attacks, and privilege escalation attacks.
Mitigation
Do not accept serialized objects from untrusted sources.
- Using Components with Known Vulnerabilities
Attackers exploit known vulnerabilities in frameworks, libraries, and other software modules running with the same privileges as the app.
Mitigation
Have a patch management process for frameworks and libraries and only obtain components from trusted sources.
- Insufficient logging and monitoring
Attackers leverage the lack of monitoring and timely responses to exploit systems.
Mitigation
Log all access control, login, and server-side input validation failures with sufficient user context. Hold them for the time necessary to identify suspicious accounts and allow for delayed forensic analysis.
