Salting and hashing are techniques that can improve the security of passwords stored in a database by making them harder to crack or reverse-engineer by hackers who might access the database12.

Salting is the process of adding a unique, random string of characters known only to the site to each password before it is hashed2. Hashing is the process of converting a password into a fixed-length string of characters, which cannot be reversed3. Salting and hashing ensure that the encryption process results in a different hash value, even when two passwords are the same1. This makes it more difficult for an attacker to use pre-computed tables or dictionaries to guess the passwords, or to exploit duplicate hashes in the database4.

OWASP (Open Web Application Security Project) is a non-profit organization that provides resources and guidance for improving the security of web applications. It can be the best resource for a software developer who is looking to improve secure coding practices for web applications by offering various tools, frameworks, standards, cheat sheets, testing guides, etc., that cover various aspects of web application security development and testing

An evil twin attack is when an attacker sets up a fake Wi-Fi network that looks like a legitimate network, but is designed to capture user data that is sent over the network. In this case, the user's laptop is constantly disconnecting and reconnecting to the Wi-Fi network, indicating that it is connecting to the fake network instead of the legitimate one. Once the user connects to the fake network, they are unable to access shared folders or other network resources, as those are only available on the legitimate network.

Code signing is a cryptographic process that allows software developers to digitally sign their code. This ensures that the code has not been tampered with since it was signed and that it came from a trusted source.

Testing input validation on the user input fields is important for preventing malicious code from being entered into a system. However, it does not address the authenticity of the code itself.

Performing static code analysis on the software can help to identify security vulnerabilities. However, it cannot guarantee that the code has not been tampered with.

Ensuring secure cookies are used is important for preventing unauthorized access to user data. However, it does not address the authenticity of the code itself.

Therefore, the most appropriate option to ensure the authenticity of the code created by the company is to perform code signing on the software.

Here are some additional benefits of code signing:

• It can help to prevent malware from being installed on users' computers.
• It can help to protect intellectual property.
• It can help to improve user trust.

Capacity planning is the process of determining the resources needed to meet the demand for a service or product. It involves estimating the number of staff members required to sustain the business in the case of a disruption, as well as other factors such as equipment, space, and budget12.

Redundancy, geographic dispersion, and tabletop exercise are not directly related to determining the staff members needed for business continuity. Redundancy is the duplication of critical components or functions to increase reliability and availability2. Geographic dispersion is the distribution of resources across different locations to reduce the impact of a localized disaster2. Tabletop exercise is a simulation of a potential scenario that tests the effectiveness of a business continuity plan

 A jump server is a device that acts as an intermediary between users and other devices on a network. A jump server can provide a secure and controlled access point to the legacy devices without exposing them directly to the network. A jump server can also enforce authentication, authorization, logging, and auditing policies.

SQLi stands for SQL injection, which is a type of web security vulnerability that allows an attacker to execute malicious SQL statements on a database server. SQLi can result in data theft, data corruption, denial of service, or remote code execution.

The attacker in the web server log is trying to exploit a SQLi vulnerability by sending a malicious GET request that contains a UNION ALL SELECT statement. This statement is used to combine the results of two or more SELECT queries into a single result set. The attacker is attempting to retrieve user login, user pass, and user email from the wp users table, which is a WordPress database table that stores user information. The attacker may use this information to compromise the WordPress site or the users’ accounts.

According to Professor Messer’s video1, VDI stands for Virtual Desktop Infrastructure and it is a deployment model where employees use their personal computers to access a virtual machine that runs the company’s operating system and applications.

In the scenario described, the company is implementing a virtual desktop infrastructure (VDI) deployment model [1]. This allows employees to access the cloud computing environment using their personal computers, while the company manages the operating system. The VDI model is suitable for remote work scenarios because it provides secure and centralized desktop management, while allowing employees to access desktops from any device.
