DevSecOps stands forDevelopment, Security, and Operationsand represents the integration of security practices within the DevOps process from the very beginning. The key difference between traditional DevOps and DevSecOps is thatDevSecOps embeds security as a core componentrather than an afterthought.

In traditional DevOps, security is often handled as a separate process at the end of the development lifecycle. However, this can lead to vulnerabilities being identified late, increasing the cost and effort required to fix them.

In DevSecOps, security is "baked in" from the start,involving practices such as:

Automated security testing:Integrating security checks into CI/CD pipelines.

Continuous monitoring:Real-time threat detection during development and production.

Collaboration:Cross-functional teams working together to maintain security at each stage.

Why Other Options Are Incorrect:

A. Removes the need for a separate security team:This is false as DevSecOps does not eliminate security teams; it integrates them within the development lifecycle.

B. Focuses on automating development without security:The opposite is true; DevSecOps specifically focuses on integrating security.

C. Reduces development time by skipping security checks:This contradicts the core principle of DevSecOps, which enhances security without sacrificing speed.

MFA enhances security by requiring multiple independent forms of authentication, making it harder for attackers to gain unauthorized access. Reference: [Security Guidance v5, Domain 5 - IAM]

Establishing a cloud deployment registry is crucial for cloud incident response because it helps track critical information related to the cloud environment, such as incident support options, account details, and contact information for cloud service providers (CSPs). This registry provides a central place where key details about cloud services and deployments are documented, allowing the incident response team to quickly access necessary information, escalate issues to the appropriate CSP support teams, and coordinate response efforts effectively.

Passwordless authentication removes the reliance on traditional passwords and instead relies on strong, cryptographic-based login mechanisms. The primary technology behind passwordless authentication is the use of local tokens or certificates, particularly implemented through protocols like FIDO2 and WebAuthn.

These mechanisms work by storing a private key on the user’s device (like a hardware security module or TPM), while the public key is stored with the cloud service. When a login attempt is made, the system uses asymmetric cryptography to verify the user—without ever transmitting a secret like a password.

“Passwordless authentication is enabled by mechanisms such as biometric verification and secure local credentials like hardware-bound certificates or tokens. The use of cryptographic authenticators (such as FIDO2) is becoming the cornerstone of secure, phishing-resistant authentication.”

Also supported by the Cloud Controls Matrix (CCM) under IAM-12:

“Utilize multifactor authentication or strong authentication mechanisms such as cryptographic tokens or certificates for user access to cloud services.”
