    Assignment Prompt & Instructions

    Hacking web servers involves gaining unauthorized access to the server that hosts a website or web application. This can be done through various techniques and vulnerabilities, and once access is gained, hackers may exploit the server for malicious purposes such as data theft, website defacement, or using it as a platform for further attacks.
    Here are some common methods hackers use to hack web servers:
    1. **Exploiting Vulnerabilities**: Hackers often exploit known vulnerabilities in server software, operating systems, or web applications. These vulnerabilities could be in the form of software bugs, misconfigurations, or outdated software versions.
    2. **SQL Injection (SQLi)**: SQL injection attacks occur when attackers inject malicious SQL queries into input fields of a web application, exploiting vulnerabilities in the application's database layer. If successful, attackers can gain unauthorized access to the server's database and extract sensitive information or modify data.
    3. **Cross-Site Scripting (XSS)**: XSS attacks involve injecting malicious scripts into web pages viewed by other users. If a web server is vulnerable to XSS, attackers can execute arbitrary scripts on users' browsers, potentially stealing their session cookies or performing other malicious actions.
    4. **Brute Force Attacks**: In a brute force attack, hackers attempt to guess usernames and passwords by systematically trying different combinations until they find the correct credentials. This can be effective if the server allows unlimited login attempts or if weak passwords are used.
    5. **Remote Code Execution (RCE)**: RCE vulnerabilities allow attackers to execute arbitrary code on the server remotely. If an attacker can exploit an RCE vulnerability, they can gain full control over the server, allowing them to install backdoors, modify files, or execute commands.
    6. **File Inclusion Vulnerabilities**: File inclusion vulnerabilities occur when an application allows an attacker to include a file from the server filesystem. By exploiting this vulnerability, attackers can execute arbitrary code, read sensitive files, or escalate their privileges.
    Hacking web servers poses significant risks to both the server owner and its users. To protect against such attacks, server administrators should regularly update software, apply security patches, use strong authentication mechanisms, employ web application firewalls, and conduct regular security audits and penetration testing. Additionally, developers should follow secure coding practices to minimize the risk of introducing vulnerabilities into their applications.
    **Week Assignment:**
    1. What is a SQL injection attack, and how can it be used to compromise a web server? Provide an example scenario.
    2. Explain the concept of remote code execution (RCE) and describe how it can be exploited to hack into a web server.
    3. What role does cross-site scripting (XSS) play in hacking web servers, and how can developers mitigate the risk of XSS attacks?
    4. Describe the process of brute force attacks on web servers. What measures can server administrators take to defend against brute force attacks?
    5. How can server misconfigurations lead to vulnerabilities that hackers exploit to gain unauthorized access to web servers? Provide examples of common misconfigurations and their potential impact.
    **Assignment Requirments:**
    – Please have APA standard format for paper
    – Please use at least 5 references and 3 references must be from the ANU library
    – Citations must be included
    – Write at least 3 pages on the questions that have been asked.

    Domain-3: Security Engineering
    The Security Engineering domain contains the concepts, principles, structures, and standards used to design, implement, monitor, and secure operating systems, equipment, networks, applications, and those controls used to enforce various levels of confidentiality, integrity, and availability. Information security architecture and design covers the practice of applying a comprehensive and rigorous method for describing a current and/or future structure and behavior for an organization’s security processes, information security systems, personnel and organizational sub-units, so that these practices and processes align with the organization’s core goals and strategic direction. Cryptography examines the principles, means, and methods of applying mathematical algorithms and data transformations to information to ensure its integrity, confidentiality, and authenticity. Physical security focuses on the threats, vulnerabilities, and countermeasures that can be utilized to physically protect an enterprise’s resources and sensitive information. These resources include people, the facility in which they work, and the data, equipment, support systems, media, and supplies they utilize. Physical security describes measures that are designed to deny access to unauthorized personnel (including attackers) from physically accessing a building, facility, resource, or stored information, and guidance on how to design structures to resist potentially hostile acts. In addition to preventing unauthorized personnel from accessing information, a focus on physical security makes it possible to ensure protection for users from hazards like fire as well as providing for clearly marked safe passages out of the facility. Explaining the “what,” “why,” and “how” of this domain will help frame the rest of the chapter.
