Enterprise, governments, and financial institutions have greater security with WPA3-Enterprise. WPA3-Enterprise builds upon WPA2 and ensures the consistent application of security protocol across the network.

WPA3-Enterprise also offers an optional mode using 192-bit minimum-strength security protocols and cryptographic tools to raised protect sensitive data:

• Authenticated encryption: 256-bit Galois/Counter Mode Protocol (GCMP-256)

• Key derivation and confirmation: 384-bit Hashed Message Authentication Mode (HMAC) with Secure Hash Algorithm (HMAC-SHA384)

• Key establishment and authentication: Elliptic Curve Diffie-Hellman (ECDH) exchange and Elliptic Curve Digital Signature Algorithm (ECDSA) employing a 384-bit elliptic curve

• Robust management frame protection: 256-bit Broadcast/Multicast Integrity Protocol Galois Message Authentication Code (BIP-GMAC-256)

The 192-bit security mode offered by WPA3-Enterprise ensures the proper combination of cryptographic tools are used and sets a uniform baseline of security within a WPA3 network.

It protects sensitive data using many cryptographic algorithms It provides authenticated encryption using GCMP-256 It uses HMAC-SHA-384 to generate cryptographic keys It uses ECDSA-384 for exchanging keys

A brute-force attack is the most exhaustive password-cracking method. It tries every possible combination of characters (letters, numbers, and symbols) until the correct password is found.

From CEH v13 Courseware:

Module 6: Password Cracking Techniques

CEH v13 Study Guide states:

“Brute-force attacks try every possible combination until the correct password is discovered. It’s resource-intensive but guarantees success if enough time and processing power is available.”

Incorrect Options:

B: Refers to social engineering or coercion.

C: Describes a dictionary attack.

D: Refers to a rainbow table attack.

E: Not a cracking method.

A Multipartite Virus is designed to infect both the boot sector and executable files of a system. This makes it more complex and harder to remove than viruses that target only one area. It can spread in multiple ways and activate under different conditions depending on whether the infected file or boot sector is accessed first.

CEH v13 Official Curriculum states:

“Multipartite viruses infect both the boot sector and program files. They are difficult to remove and can reinfect the system unless both locations are cleaned simultaneously.”

Incorrect Options:

A. Polymorphic viruses change their code signatures but do not necessarily target both boot and executable areas.

B. Stealth viruses conceal their presence, often by intercepting system calls.

D. Macro viruses infect macro-enabled files, typically in Microsoft Office documents.

Comprehensive and Detailed Explanation:

Non-repudiation ensures that a sender cannot deny having sent a message. This is typically achieved through digital signatures or logs which verify the origin and integrity of communications.

From CEH v13 Courseware:

Module 10: Cryptography → Security Services

“Non-repudiation prevents entities from denying their actions, such as sending emails or digital transactions.”
