QUESTION 10
This wireless security protocol allows 192-bit minimum-strength security protocols and cryptographic tools to protect
sensitive data, such as GCMP-2S6. MMAC-SHA384, and ECDSA using a 384-bit elliptic curve. Which is this wireless
security protocol?
A. WPA2 Personal
B. WPA3-Personal
C. WPA2-Enterprise
D. WPA3-Enterprise
Correct Answer: D
Enterprise, governments, and financial institutions have greater security with WPA3-Enterprise. WPA3Enterprise 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.

QUESTION 2
in this attack, an adversary tricks a victim into reinstalling an already-in-use key. This is achieved by manipulating and
replaying cryptographic handshake messages. When the victim reinstall the key, associated parameters such as the
incremental transmit packet number and receive packet number are reset to their initial values. What is this attack
called?
A. Chop chop attack
B. KRACK
C. Evil twin
D. Wardriving
Correct Answer: B
 In this attack KRACK is an acronym for Key Reinstallation Attack. KRACK may be a severe replay attack on Wi-Fi
Protected Access protocol (WPA2), which secures your Wi-Fi connection. Hackers use KRACK to take advantage of a
vulnerability in WPA2. When in close range of a possible victim, attackers can access and skim encrypted data using
KRACK. How KRACK WorksYour Wi-Fi client uses a four-way handshake when attempting to attach to a protected
network. The handshake confirms that both the client — your smartphone, laptop, et cetera — and therefore the access
point share the right credentials, usually a password for the network. This establishes the Pairwise passkey (PMK),
which allows for encoding .Overall, this handshake procedure allows for quick logins and connections and sets up a
replacement encryption key with each connection. this is often what keeps data secure on Wi-Fi connections, and every
one protected Wi-Fi connections use the four-way handshake for security. This protocol is that the reason users are
encouraged to use private or credential-protected Wi-Fi instead of public connections.KRACK affects the third step of
the handshake, allowing the attacker to control and replay the WPA2 encryption key to trick it into installing a key
already in use. When the key\\’s reinstalled, other parameters related to it — the incremental transmit packet number
called the nonce and therefore the replay counter — are set to their original values.Rather than move to the fourth step
within the four-way handshake, nonce resets still replay transmissions of the third step. This sets up the encryption
protocol for attack, and counting on how the attackers replay the third- step transmissions, they will take down Wi-Fi
security. Why KRACK may be a ThreatThink of all the devices you employ that believe Wi-Fi. it isn\\’t almost laptops
and smartphones; numerous smart devices now structure the web of Things (IoT). due to the vulnerability in WPA2,
everything connected to Wi-Fi is in danger of being hacked or hijacked.Attackers using KRACK can gain access to
usernames and passwords also as data stored on devices. Hackers can read emails and consider photos of transmitted data then use that information to blackmail users or sell it on the Dark Web.Theft of stored data requires more steps, like
an HTTP content injection to load malware into the system. Hackers could conceivably take hold of any device used
thereon Wi-Fi connection. Because the attacks require hackers to be on the brink of the target, these internet security
threats could also cause physical security threats.On the opposite hand, the necessity to be in close proximity is that the
only excellent news associated with KRACK, as meaning a widespread attack would be extremely difficult.Victims are
specifically targeted. However, there are concerns that a experienced attacker could develop the talents to use HTTP
content injection to load malware onto websites to make a more widespread affect. Everyone is in danger from KRACK
vulnerability. Patches are available for Windows and iOS devices, but a released patch for Android devices is currently
in question (November 2017). There are issues with the discharge , and lots of question if all versions and devices are
covered.The real problem is with routers and IoT devices. These devices aren\\’t updated as regularly as computer
operating systems, and for several devices, security flaws got to be addressed on the manufacturing side. New devices
should address KRACK, but the devices you have already got in your home probably aren\\’t protected. The best
protection against KRACK is to make sure any device connected to Wi-Fi is patched and updated with the newest
firmware. that has checking together with your router\\’s manufacturer periodically to ascertain if patches are available.
The safest connection option may be a private VPN, especially when publicly spaces. If you would like a VPN for private
use, avoid free options, as they need their own security problems and there\\’ll even be issues with HTTPs. Use a paid
service offered by a trusted vendor like Kaspersky. Also, more modern networks use WPA3 for better security.Avoid
using public Wi-Fi, albeit it\\’s password protection. That password is out there to almost anyone, which reduces the
safety level considerably.All the widespread implications of KRACK and therefore the WPA2 vulnerability aren\\’t yet
clear. what\\’s certain is that everybody who uses Wi-Fi is in danger and wishes to require precautions to guard their
data and devices. 

QUESTION 3
Kevin, a professional hacker, wants to penetrate CyberTech Inc.\\’s network. He employed a technique, using which he
encoded packets with Unicode characters. The company\\’s IDS cannot recognize the packet, but the target web server
can decode them.
What is the technique used by Kevin to evade the IDS system?
A. Desynchronization
B. Obfuscating
C. Session splicing
D. Urgency flag
Correct Answer: B
Explanation: Adversaries could decide to build an possible or file difficult to find or analyze by encrypting, encoding, or
otherwise obfuscating its contents on the system or in transit. this is often common behavior which will be used across
totally different platforms and therefore the network to evade defenses. Payloads may be compressed, archived, or
encrypted so as to avoid detection. These payloads may be used throughout Initial Access or later to mitigate detection.
typically a user\\’s action could also be needed to open and Deobfuscate/ Decode Files or info for User Execution. The
user can also be needed to input a parole to open a parole protected compressed/encrypted file that was provided by
the mortal. Adversaries can also used compressed or archived scripts, like JavaScript. Portions of files can even be
encoded to cover the plain-text strings that will otherwise facilitate defenders with discovery. Payloads can also be split
into separate, ostensibly benign files that solely reveal malicious practicality once reassembled. Adversaries can also
modify commands dead from payloads or directly via a Command and Scripting Interpreter. surroundings variables,
aliases, characters, and different platform/ language specific linguistics may be wont to evade signature based mostly
detections and application management mechanisms.

QUESTION 4
