Input sanitization is a critical security measure to prevent SQL injection attacks, which occur when an attacker exploits vulnerabilities in a website's input fields to execute malicious SQL code. By properly sanitizing and validating all user inputs, developers can prevent malicious code from being executed, thereby securing the website against such attacks.

Detailed Explanation:Data sovereignty refers to the principle that data stored in another country remains subject to the originating country's laws. This is a common concern in cloud computing. Reference:
CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Data Sovereignty and Regulatory Compliance".

Detailed Explanation:Standard operating procedures (SOPs) outline the steps to be followed to maintain a secure baseline, such as testing and deploying patches while minimizing risk to the system. Reference:
CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Patch Management and Baseline Compliance".

The CCTV system and signs about the possibility of being filmed serve as both deterrent and detective controls.
* Deterrent controls: Aim to discourage potential attackers from attempting unauthorized actions.
Posting signs about CCTV serves as a deterrent by warning individuals that their actions are being monitored.
* Detective controls: Identify and record unauthorized or suspicious activity. The CCTV system itself functions as a detective control by capturing and recording footage that can be reviewed later.
* Preventive controls: Aim to prevent security incidents but are not directly addressed by the CCTV and signs in this context.
* Corrective controls: Aim to correct or mitigate the impact of a security incident.
* Directive controls: Provide guidelines or instructions but are not directly addressed by the CCTV and signs.
* Compensating controls: Provide alternative measures to compensate for the absence or failure of primary controls.

Detailed Explanation:
Corrective controls, such as auditing and versioning, help prevent unauthorized changes to financial data, ensuring data integrity and compliance with regulations. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Controls for Financial Systems".
