Since You are a cyber forensic specialist, and you are asked to retrieve the password of an employee account suspected of being an imposter, the method that will be the easiest for you to use when retrieving the password is option d. Rule attack.
What is dictionary attack?A kind of brute force attack where a hacker uses a "dictionary list" of terms and expressions that people and companies frequently use to try to break a password-protected security system is the term dictionary attack.
Note that Hashcat's rule-engine was created to be 100% compatible with John the Ripper and PasswordsPro rules and vice versa for all functions that share the same letter name. Later, we began introducing some of our own, incompatible functions. To avoid confusion, these functions were given their own letter names.
Therefore, based on the above, When an attacker is aware of the rules that a system's passwords are built on, such as "alphanumeric and eight characters long," they can target their password cracking technique.

Service Set Identifier (SSID) is the element that the wi-fi developers create to use as another level of naming to apply to the bss or ibss to help the connection happen.
What is a wi-fi?To connect computers, tablets, smartphones, and other devices to the internet, Wi-Fi is a wireless technology that is used.
Wi-Fi refers to a radio signal that is transmitted from a wireless router to a nearby device, which then converts the signal into information that can be seen and used. To the router, which is wired or connected via cable to the internet, the device sends a radio signal back.
In a nutshell, a Wi-Fi network is just a wireless router that distributes an internet connection to a number of devices in a building or home. The router, which is directly connected to your internet modem, serves as a hub to disseminate the internet signal to all of your Wi-Fi capable devices. As long as you are in your network's service area, this gives you the freedom to stay connected to the internet.

Therefore, one can say that It is a type of abstract data that associates values with keys. An array of buckets or slots are used in a hash table to provide an index, also known as a hash code, from which the requested data can be retrieved. The key is hashed during lookup, and the resulting hash shows where the relevant value is kept.

Hash Tables need to deal with collisions. Which of the hash table collision- handling schemes could tolerate a load factor above 1 and which could not? a. Hint: Think about which of the schemes use the array supporting the hash table exclusively and which of the schemes use additional storage external to the hash table. b. Assume you want to hash the keys 12, 44, 13, 88, 23, 94, 11, 39, 20, 16, 5 and store them in a hash table. Implement linear probing, and double hashing to handle collision. Print out the positions of keys stored. Hash functions for linear probing and double hashing as described as follows. Linear probing: h(k) (3k+5) mod 11 Double hashing: hi(k) (3k+5) mod 11, h2(k)-7 (k mod 7)
Which network device would be the most appropriate to provide stateful packet filtering, email filtering, and vpn services?
A Universal Threat Management (UTM) device is a multipurpose security tool that may act as a VPN connection point for remote users as well as a firewall, proxy filter, email filter, and network access control service provider.
In the past, businesses have used a variety of point security technologies to counteract particular cybersecurity threats. A company might have a separate firewall, antivirus software, etc. Because a UTM solution can handle a variety of network security tasks in a single appliance, it reduces the requirement for this group of independent solutions.
At the network perimeter, unified threat management tools are set up to scan all incoming and outgoing data. The UTM system gains the required visibility into network packets via deep packet inspection (DPI), allowing it to identify inbound threats and deny web requests to inappropriate or dangerous websites. A security team can also control each of these aspects using a single dashboard that UTM offers.
