 In the context of IoT architecture, the component that collects data from IoT devices and performs data preprocessing is typically referred to as a Gateway. This device acts as an intermediary between the IoT devices and the cloud infrastructure. It is responsible for aggregating data, performing initial processing, and then transmitting the data to the cloud for further storage and analysis. Gateways are crucial for reducing latency, providing local data buffering, and ensuring that only necessary data is sent to the cloud, thereby optimizing network and storage resources.

Stephen used a replay attack technique to gain unauthorized access to the target server. In this scenario, he captured authentication tokens transmitted by the user and then replayed those tokens back to the server to impersonate the user and gain access.

SQL Injection (SQLi) is a prevalent vulnerability in web applications that occurs when an attacker can insert or manipulate SQL queries using untrusted user input. This vulnerability is exploited by constructing dynamic SQL statements that include user-provided data without proper validation or sanitization. When applications concatenate user input values directly into SQL queries, they become susceptible to SQLi, as attackers can craft input that alters the intended SQL command structure, leading to unauthorized access or manipulation of the database.

To mitigate SQL injection risks, it’s crucial to avoid creating dynamic SQL queries by concatenating input values. Instead, best practices such as using prepared statements with parameterized queries, employing stored procedures, and implementing proper input validation and sanitization should be followed. These measures help ensure that user input is treated as data rather than part of the SQL code, thus preserving the integrity of the SQL statement and preventing injection attacks.

• SQL Injection (SQLi):This common web application vulnerability arises when untrusted user input is directly used to construct SQL queries. Attackers can manipulate the input to alter the structure of the query, leading to data exposure, modification, or even deletion.
• Dynamic SQL and Concatenation:Dynamically constructing SQL statements by concatenating user input is highly dangerous. Consider this example:

SQL

SELECT*FROMusersWHEREusername=userInput ;

An attacker can provide input like:' OR '1'='1'--resulting in this query:

SQL

SELECT*FROMusersWHEREusername=''OR'1'='1'-- ;

This query will always return true due to theORcondition and the comment (--) effectively bypassing authentication.

The application layer in IoT architecture is responsible for delivering services to respective users from different sectors such as building, industrial, manufacturing, automobile, security, and healthcare. It provides the user interfaces and applications that interact with IoT devices and systems.

A push notification is a messaging feature that originates from a server and enables the delivery of data or a message from an application to a mobile device without any explicit request from the user. It allows applications to notify users of new messages, updates, or events even when the app is not actively running on the device. Push notifications are commonly used in mobile apps to engage users and provide timely information.
