Q1.What is DoS and DDoS Attacks! DoS stands for "Denial of Service," and DDoS stands for "Distributed Denial of Service." These are cyberattacks that aim to make a computer system or network unavailable to its intended users. Here's the difference: 1. DoS Attack: - In a DoS attack, a single attacker uses various methods to flood a target system or network with an overwhelming amount of traffic, requests, or data. - The goal is to consume the system's resources (like bandwidth, processing power, or memory) to the point where it can no longer respond to legitimate requests. 2. DDoS Attack: - DDoS attacks involve multiple compromised computers or devices (often forming a botnet) that are coordinated to launch a simultaneous attack on a target. - DDoS attacks are more powerful and challenging to mitigate because they come from multiple sources, making it difficult to distinguish legitimate traffic from the malicious traffic. SQL Injection is a common type of cyberattack that targets databases and can have serious consequences if successfully executed. Here's how it works: 2.How an SQL Injection help in cyber attactar 1. Vulnerable Input: SQL Injection takes advantage of websites or applications that have improper input validation and don't properly sanitize user inputs. When a user provides input (such as through a web form), the application doesn't validate or sanitize the data properly. 2. Malicious SQL Queries: An attacker can then submit malicious SQL code as part of the input. For example, they might input something like `' OR 1=1; --`. This input can be used to manipulate the SQL queries that the application sends to its database. 3. Exploiting Weaknesses: If the application doesn't handle this input securely, the malicious SQL code is executed by the database server as a legitimate query. In the example above, `1=1` is always true, so the attacker gains unauthorized access to the database. 4. Unauthorized Data Access: With a successful SQL Injection, an attacker can view, modify, or delete data within the database. They may also extract sensitive information, such as usernames, passwords, credit card numbers, or other confidential data. 5. Further Attacks: Once an attacker gains access to the database, they can use this information to launch further attacks or compromise the security of the entire system. Preventing SQL Injections requires secure coding practices, such as using parameterized queries or prepared statements, input validation, and output encoding to ensure that user inputs are properly sanitized before interacting with the database. Additionally, keeping software and databases up to date with security patches is crucial in defending against SQL Injection attacks. Q3.Write short note on key loggers.

Explain in detail. Steganography is the practice of concealing one piece of information within another to hide the existence of the embedded data. This technique is often used to send hidden messages or hide sensitive information within seemingly innocuous content. Unlike cryptography, which focuses on making the content of a message unreadable to unauthorized users, steganography aims to make the very existence of the message undetectable. Here's a more detailed explanation of steganography: 1. **Concept**: Steganography is derived from the Greek words "steganos" (meaning "covered") and "graphie" (meaning "writing"). It involves hiding a secret message (data) within a cover medium (such as an image, audio file, text, or video) in such a way that it's difficult for anyone to know the hidden data exists. 2. **Types of Media**: Steganography can be applied to various types of media, including text, images, audio, video, or even network protocols. 3. **Techniques**: - **Least Significant Bit (LSB)**: One of the most common methods is LSB replacement in digital images. In this technique, the least significant bits of pixel values are replaced with the secret message bits. This is often used in image steganography. - **Frequency Domain**: In audio steganography, changes may be introduced in the frequency domain by slightly modifying the amplitude of specific audio frequencies. - **Text-Based**: In text steganography, hidden messages may be encoded using techniques like letter spacing, punctuation, or word choice. 4. **Key and Password**: Many steganography methods use a key or password to hide and reveal the data. The recipient needs to know the same key or password to extract the hidden message. 5. **Applications**: - **Cryptography**: Steganography can complement encryption. Hidden data can be encrypted before embedding it in the cover medium. - **Data Protection**: It can be used to protect sensitive data during transmission or storage. - **Digital Watermarking**: Steganography is also used for digital watermarking to embed information for copyright or ownership tracking. - **Covert Communication**: It can be used for covert communication in espionage or cybercriminal activities. 6. **Detection**: Detecting steganography is a challenging task because it doesn't alter the cover medium significantly. Various steganalysis techniques have been developed to identify the presence of hidden data. 7. **Ethical and Legal Considerations**: The use of steganography can raise ethical and legal concerns. While it has legitimate applications, it can also be used for malicious purposes, and its legality varies by jurisdiction. 8.What are the aspects of any contract in cyber Law.
