Trust is a critical component of ethical hacking, as the goal of ethical hacking is to identify vulnerabilities and weaknesses in an organization's systems in order to improve security. Without trust, ethical hackers may not be able to gain access to the systems and information necessary to carry out their work.

Ethical hacking is the practice of using hacking techniques for the purpose of identifying vulnerabilities and weaknesses in computer systems, networks, and applications, with the goal of improving their security.

It is conducted with the permission and knowledge of the system owner, and aims to enhance the security of the targeted system rather than cause harm or damage.

Trust is built through clear communication and transparency between the ethical hacker and the organization being tested. The ethical hacker must establish their credentials and provide clear explanations of their methods and goals. They must also respect the privacy and confidentiality of the organization's data and systems, and obtain permission before conducting any testing or analysis.

The term that describes the second core IPSec security protocol that can perform authentication to provide integrity protection, although not for the outermost IP header is called the Encapsulating Security Payload (ESP) protocol.

ESP is a protocol used for securing IP packets by providing confidentiality, integrity, and authentication. It is inserted between the IP packet and the new IP header, encapsulating the entire original packet, and adding its own header, trailer, and authentication fields. The authentication is performed using a cryptographic algorithm, such as HMAC-SHA1, to provide integrity protection to the data being transmitted.

ESP provides a higher level of security than the Authentication Header (AH) protocol, as it not only provides authentication but also encrypts the data. However, ESP does not provide protection to the outermost IP header, which is why it is sometimes used in combination with the AH protocol to provide both authentication and integrity protection to the entire packet, including the outermost IP header.

One minute of CDDA (Compact Disc Digital Audio) music requires in excess of 10 MB of storage space.

CDDA is the standard format for audio compact discs and is a high-quality, uncompressed digital audio format that uses a sampling rate of 44.1 kHz and a bit depth of 16 bits. This results in a large file size of approximately 10.5 MB per minute of audio.Other compressed audio formats, such as MP3 or AAC, use lossy compression techniques to reduce file size while maintaining acceptable audio quality. This allows for much smaller file sizes while still providing high-quality audio, typically resulting in a file size of around 1-2 MB per minute of audio, depending on the level of compression used.

The CREATE VIEW command includes the words CREATE VIEW, followed by the name of the view, the word c.​ AS, and then a query.​

The CREATE VIEW command is used in SQL to create a virtual table, which is a subset of data from one or more tables in the database.

The syntax for the CREATE VIEW command includes the words CREATE VIEW, followed by the name of the view, the word "AS", and then a query that defines the columns and rows of the view.
The "AS" keyword is used to specify that the following query will define the view. It is a crucial part of the syntax, as it separates the name of the view from the query that defines it. Without the "AS" keyword, the SQL engine would not be able to differentiate between the name of the view and the query that defines it, leading to syntax errors.
In addition to the "AS" keyword, the CREATE VIEW command also allows for the use of various other keywords and clauses, such as SELECT, FROM, WHERE, GROUP BY, and ORDER BY. These clauses can be used to specify the columns to be included in the view, the tables to be used as the source of data, and any filtering or sorting that should be applied to the data.
Overall, the CREATE VIEW command is a powerful tool in SQL that allows users to create customized views of data from one or more tables in the database. By using the "AS" keyword and other clauses, users can define complex queries that can be reused and shared across different applications and users.

Symmetric encryption is a type of encryption where the same secret key is used for both encryption and decryption of the data. The Data Encryption Standard (DES) is a symmetric key algorithm that uses a 56-bit key to encrypt and decrypt data. While DES was widely used in the past, it is now considered insecure due to its short key length and vulnerability to brute-force attacks.

Triple DES (3DES), also known as TDEA (Triple Data Encryption Algorithm), is a more secure version of DES that uses three keys and applies the DES algorithm three times in sequence to provide stronger encryption. 3DES is still used in some applications, but it is being phased out in favor of newer algorithms. Advanced Encryption Standard (AES) is a symmetric key algorithm that uses a block cipher to encrypt and decrypt data. AES is widely used in modern cryptography and is considered secure due to its strong encryption and key length options.

Asymmetric encryption, also known as public-key encryption, uses two keys – a public key for encryption and a private key for decryption. This allows for secure communication without the need for a shared secret key. Asymmetric encryption is often used in secure online communication, such as HTTPS and SSL/TLS protocols. In summary, symmetric encryption is fast and efficient but requires the secure distribution of the shared secret key. DES and 3DES are older symmetric encryption algorithms that have been largely replaced by AES. Asymmetric encryption provides secure communication without the need for a shared secret key and is commonly used in modern cryptography.

False. A primary key can comprise either a single column or multiple columns (composite key). The primary key uniquely identifies each row in a table and ensures data integrity.

A primary key is a special type of field or set of fields in a database table that uniquely identifies each record in the table. It is a constraint that enforces the integrity and consistency of data in the table. A primary key is used to ensure that each record in the table can be uniquely identified, and to establish relationships with other tables in the database.

A primary key can be a single field or a combination of fields in a table. It must be unique, meaning that no two records in the table can have the same value for the primary key field(s). It must also be not null, meaning that the primary key field(s) cannot be empty or null.

A primary key can be created when a table is first created, or it can be added to an existing table using SQL commands or the table design view in a database management system. Primary keys are typically indexed for faster searching and sorting of data.
