SASE stands for Secure Access Service Edge. It is a cloud-based service that combines network and security functions into a single integrated solution. SASE can help reduce traffic on the VPN and internet circuit by providing secure and optimized access to the data center and cloud applications for remote employees. SASE can also monitor and enforce security policies on the remote employee internet traffic, regardless of their location or device. SASE can offer benefits such as lower costs, improved performance, scalability, and flexibility compared to traditional VPN solutions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 457-458 1

A disaster recovery plan (DRP) is a set of policies and procedures that aim to restore the normal operations of an organization in the event of a system failure, natural disaster, or other emergency. A DRP typically includes the following elements:

A risk assessment that identifies the potential threats and impacts to the organization’s critical assets and processes.

A business impact analysis that prioritizes the recovery of the most essential functions and data.

A recovery strategy that defines the roles and responsibilities of the recovery team, the resources and tools needed, and the steps to follow to restore the system.

A testing and maintenance plan that ensures the DRP is updated and validated regularly. A DRP is required for an organization to properly manage its restore process in the event of system failure, as it provides a clear and structured framework for recovering from a disaster and minimizing the downtime and data loss. References = CompTIA Security+ Study Guide (SY0-701), Chapter 7: Resilience and Recovery, page 325.

The correct answer is B. Code signing.

Code signing uses a digital signature to verify the authenticity and integrity of software, scripts, drivers, or compiled binaries. If a compiled binary is signed, the production environment can verify that the binary came from a trusted source and has not been modified since it was signed.

This supports integrity because any unauthorized change to the binary would invalidate the signature.

Why the other options are incorrect:

A. Input validation

Input validation helps prevent attacks such as injection, cross-site scripting, and malformed input attacks. It does not verify the integrity of compiled binaries.

C. SQL injection

SQL injection is an attack technique, not a security measure.

D. Static analysis

Static analysis reviews source code or binaries without executing them. It can help identify vulnerabilities before deployment, but it does not provide ongoing integrity verification of compiled binaries in production.

Therefore, the best answer is code signing.

Integrating each SaaS solution with an Identity Provider (IdP) is the most effective way to address the security issue. This approach allows for Single Sign-On (SSO) capabilities, where users can access multiple SaaS applications with a single set of credentials while maintaining strong password policies across all services. It simplifies the user experience and ensures consistent security enforcement across different SaaS platforms.
