SY0-701 2.3: Vulnerability Types

Security+ Topic

Vulnerability Types for Security+

This Security+ topic covers vulnerability class recognition: the underlying weakness, insecure condition, platform weakness, provider weakness, or flaw category that could be exploited.

Start first lesson

5 lessons in this topic

1

Application And Web Vulnerabilities

Recognize application and web vulnerability classes such as memory injection, buffer overflow, race conditions, SQL injection, and cross-site scripting.

2

OS, Hardware, And Firmware Vulnerabilities

Explain OS-based, firmware, end-of-life, and legacy vulnerabilities at a classification level.

3

Virtualization And Cloud Vulnerabilities

Recognize virtualization and cloud-specific weaknesses such as VM escape, resource reuse, and cloud misconfiguration.

4

Supply Chain And Cryptographic Vulnerabilities

Classify weaknesses caused by service providers, hardware providers, software providers, cryptographic flaws, or malicious updates.

5

Mobile, Misconfiguration, And Zero-Day Vulnerabilities

Recognize mobile device vulnerabilities, side loading, jailbreaking, misconfiguration, and zero-day exposure without turning into remediation workflow.

Common mistakes to avoid

1

Learners often confuse SQLi and XSS because both involve untrusted input. SQLi changes database query behavior. XSS runs script in a browser.

2

Learners often treat end-of-life and legacy as the same. End-of-life is a support status. Legacy is an older retained technology pattern.

3

Learners often label every cloud-hosted issue as cloud-specific. If the flaw would be the same in a non-cloud web application, such as SQLi or XSS, classify the application or web vulnerability.

4

Learners often confuse supply chain vector, supply chain vulnerability, and third-party risk management. The vector is the trusted path through a provider. The vulnerability is the weakness introduced by that provider, component, or update path.
