The entry fields of web forms lacking input validation are vulnerable to SQL injection attacks. This is a type of attack where malicious actors inject SQL code into web form fields to gain unauthorized access to a website's database. SQL injection attacks can be used to steal sensitive information, modify or delete data, or even take control of a website.

Input validation is an important security measure that helps prevent SQL injection attacks. It involves checking user input to ensure it conforms to a specific set of criteria, such as length, format, and type. If input validation is not implemented, attackers can exploit vulnerabilities in web forms to inject SQL code and gain access to sensitive information.

Other types of attacks that may be facilitated by web forms lacking input validation include spear phishing, where attackers use fraudulent emails to trick users into divulging sensitive information, and watering hole attacks, where attackers infect legitimate websites with malware to target specific groups of users. However, these attacks are not directly related to the lack of input validation in web forms, and so SQL injection remains the primary vulnerability that needs to be addressed in this context.

To protect against SQL injection attacks, web developers should implement input validation, as well as other security measures such as user authentication, access controls, and regular security audits. Additionally, users can protect themselves by being cautious about the information they share online and keeping their software and security tools up to date.

A. Encryption, when used within an organization, is the LEAST likely to interfere with vulnerability scanning results achieved by external penetration testers.

A security technique called encryption turns plain text into a coded version that cannot be decoded without the right decryption key. Encryption is implemented at the data level and has the least potential to impede the results of vulnerability scanning performed by outside penetration testers since it does not affect network traffic or packet transfer. On the other side, the outcomes of vulnerability scanning may be adversely affected by firewalls, IPSs, and containerization. While containerization may restrict access to the scanning target or erect extra security barriers that may obstruct the scanning process, firewalls and intrusion prevention systems (IPS) may block or filter out the scanning traffic. Therefore, encryption can be used to protect sensitive data within an organization without significantly impacting the accuracy of vulnerability scanning results obtained by an external penetration tester

Implementation inheritance, which involves overriding, can break encapsulation in the following ways:

1. Inheritance: When a class (subclass) inherits properties and methods from another class (superclass), it is called inheritance. This allows the subclass to reuse and extend the functionality of the superclass.

2. Encapsulation: Encapsulation is the process of hiding the internal details of an object and exposing only what is necessary. It ensures that an object's data and methods are protected from being accessed or modified directly by other parts of the program.

3. Breaking encapsulation with overriding: When a subclass overrides a method of the superclass, it can access and modify the internal data and behavior of the superclass, which might not be intended. This can lead to a breach of encapsulation, as the subclass can potentially alter the internal state or behavior of the superclass in an unintended way.

A Web Server would use threads to improve performance by allowing multiple requests to be processed concurrently, thereby increasing the server's capacity to handle more traffic.

When a web server gets a request, it generates a new thread to handle it, allowing numerous requests to be processed at the same time. Each thread can run its code path and work independently of the others, allowing the server to process several requests at the same time. This increases server performance and decreases response time for each request.

Using threads can also assist the server in avoiding blocking, which occurs when a single long-running request monopolizes server resources and prevents subsequent requests from being handled. The server can restrict the number of active threads at any given moment by employing a thread pool, ensuring that each request receives a fair amount of resources while preventing the server from becoming overburdened.

However, using threads adds complexity and cost since threads must be controlled and coordinated to minimize conflicts and preserve data integrity. Threads must be used properly and efficiently, which necessitates careful design and execution.
