BYOD, or Bring Your Own Device, is the correct answer because the company is allowing employees to use personally owned devices to access internal company resources such as email. In Security+ architecture and operations topics, mobile deployment models are important because each model shifts ownership, management, and risk differently. BYOD reduces hardware procurement costs, but it increases security concerns because the organization does not fully own or control the endpoint. Controls such as MDM, conditional access, encryption, remote wipe, acceptable use policies, and device compliance checks are commonly needed. CYOD means employees choose from approved corporate devices, while COPE means the company owns the device and permits personal use. MDM is a management control, not the deployment strategy itself.

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.

An Acceptable Use Policy (AUP) defines what users are permitted and prohibited from doing on an organization's systems, including website access. Accessing unauthorized sites is a common violation of the AUP.

The logs show an SQL injection attack. The first step is to verify if new accounts have been created, indicating a successful injection.

Detailed Explanation:Proper data sanitization ensures that sensitive data is securely erased from storage devices, preventing unauthorized access or recovery when the devices are disposed of or reused. Reference:
