Topic 1 - Types of wireless Antennas
If you need to have a communication setup for your company in Mississauga and its branch
office in Hamilton, which one would you be using? Please note, there is a small mountain
between these two locations (Hamilton Mountain), so you have to consider that as well. In order to know what the most adequate type of antenna for this scenario is, it’s
important to know all the options and their advantages and disadvantages. It can be seen in Table
1 the different types of antennas next to a small description, typical use, and an example.
Type
Description
Example
Directional
Long distance in point-to-
point communication.
This type of antenna can be used for the network connection between two buildings separated by a long distance.
Semi-Directional
Short to medium distance in point-to-point communication.
This type of antenna can be used for the Wi-Fi on small university campus.
Omni-Directional
Point-to-multipoint communication.
This type of antenna can be used for the Wi-Fi on houses or office building.
Table 1. Comparison types of antennas The primary function of an antenna is to send and receive clear signals from various
wireless devices; moreover, antennas are necessary for a wireless network to work effectively.
Three main categories of antennae are classified by their mode of operation and used in different
circumstances to address specific coverage issues. Directional, Semi-directional, and
Omnidirectional are the three classifications. Directional antenna: these antennas are genuinely specialized and have a radiation pattern
directed in a particular direction, allowing for more excellent range, better interference rejection,
2
point-to-point link capability, signal focus, and increased noise immunity, making them ideal for
various applications requiring precise and selective transmission or reception.
Semi-directional antennae: are very flexible and have a vast range of coverage patterns.
As a result, they are the type of antenna most frequently used when addressing coverage issues.
A kind of semi-directional antenna commonly used for mobile large-scale 802.11 networks due
to its flexibility and capacity. The omnidirectional antenna: radiates 360 degrees on the horizontal plane and between 7
and 80 degrees on the vertical plane. Moreover, they are typically used in point-to-multipoint
configurations. Increasing the antenna's gain, or power, flattens the radiation pattern to stretch
the horizontal coverage while restricting the vertical. Therefore, the higher the antenna's growth,
the lower the vertical convergence. For example, installing an access point with a high-gain
omnidirectional antenna in the middle of the building's first floor will give you excellent
coverage. However, the second floor's signal must be improved because the vertical range has
been curtailed. After conducting thorough research on different types of antennas, considering their
mode of operation and suitability in various circumstances, we have concluded that the most
suitable option for establishing effective communication between the company in Mississauga
and its branch office in Hamilton is the directional antenna. This decision is based on the
geographical location of both sites, considering the distance between them and the natural
obstacle present, such as a small mountain.

Hi I want to make a video presentation on this topic which should be 5 mins atleast, so need help below format:
Discussion: Misadventures of a Nation State Podcast
Discuss Darknet Diaries Episode 10. Why is this a video discussion instead of a written response? It is an important skill to master to be able to present and summarize the key concepts of a complex cybersecurity incident in a short time frame. Remember that unless you are talking to other cybersecurity professionals, probably no one thinks this stuff is as interesting as you do.
Instructions: The main purpose of the video discussion assignments is to get you to dig into the main four cybersecurity frameworks and references we use in the class. Use the context of the specific security incident to explore and explain some aspects of the NIST CSF, the CIS CSCs, ACSC Strategies to Mitigate Cyber Incidents, and the MITRE ATT&CK matrix.

"The impact of hacking on life" - For the last several years cyber-attacks/hacking are in the news on a seemingly continuous basis. Some of the most recent/largest hacking events include the Solarwinds hack that was the conduit for the major breach of many US Federal agencies and the disturbing Equifax hack from 2017. Have these events and the subsequent reporting caused you to change any habits/behaviors? Please provide your thoughts on this along with why you have or have not made any changes as a result of these events.

Nearly a decade has passed since the
National Academy of Engineers declared
Cyber Security a "grand challenge for the
next century." Every day there is news on
ways in which cyber security challenges
and responses are complicating every
aspect of our lives. Can the challenge be
solved?
As a first step to solving any problem, one
must understand its nature. So, it is
important for all cyber security analysts to
keep on top of news stories in the field. In
this discussion forum we will do just that
with the hope that everyone will make it a
daily habit throughout their career.
Today, some cyber news has been flooded
out of the headlines by Hurricane Harvey,
but as noted in this article, cyber concerns
are front and center as students return to

you will be writing an essay to discuss the evolution of hacking.
Your Essay should highlight the evolution of hacking from individuals to corporations (and their predominate locations) to cyber warfare. Include at least 5 different locations and events (more is better) to tell the story of how hacking has changed over time from the 1940's to present. Use your specific events to illustrate both when and what happened in each of these locations/events that changed the face of hacking as well as the global nature of hacking.
The events should be presented in time order. Also include images or figures, and any additional visual aids to help tell your story.
Where did the hack originate, who was the target if known, how did this event affect hacking as we know it, what was significant about this event. Your 5 or more locations should include at least 2 (preferably 3 or more) international locations as well as at least one United States location.

Founded in April 1996, Antheus Tecnologia develops and distributes Automated Fingerprint Identification Systems [AFIS], automated fingerprinting, and other systems such as iris recognition devices. Antheus Tecnologia also claims that it is the first Brazilian company to be certified by the US Federal Bureau of Investigation [FBI] and develops biometric solutions for domestic and overseas clients.
In March 2020, the security research team at SafetyDetectives discovered a significant data leak in addition to other security flaws [such as lack of password protection] relating to fingerprint data on an Antheus log server in Brazil. The research team discovered almost 2.3 million data points in total and estimated that 76,000 unique fingerprints were found on the database. Approximately 16 gigabytes of data were found on the Elasticsearch server, including highly sensitive information related to identification and biometric details.
The Antheus server investigated by the security team is an…

In 2013, Edward Snowden was hired by the NSA after previous employment with the CIA as a systems administrator. In early June of 2013 he revealed thousands of classified NSA documents to journalists Glenn Greenwald, Laura Poitras, Barton Gellman, and Ewen MacAskill about government surveillance programs. By June 21, 2013, the United States Department of Justice unsealed charges against Edward Snowden of two counts of violating the Espionage Act of 1917 and theft of government property, which identified the leak of state secrets as an act of treason.
Snowden has become a subject of controversy, both ethically and legally being seen as a traitor, a hero, a whistleblower, a dissident, and patriot.

In 2006, Hewlett-Packard Development Company LP became embroiled in a controversy over methods used toinvestigate media leaks from its board. HP Chairperson Patricia Dunn could have simply asked the directors who was the source cited in the story, sought an apology and gone from there. With some direct face-to-face communication, the story would likely have ended quickly. It did not. “Not only did investigators impersonate board members, employees and journalists to obtain their phone records, but according to multiple reports, they also surveilled an HP director and a reporter for CNet Networks Inc. They sent monitoring spyware in an e-mail to that reporter by concocting a phoney tip. They even snooped on the phone records of former CEO and Chairperson Carly Fiorina, who had launched the quest to identify media sources in the first place.” The situation continued to escalate. For example, the New York Times reported that HP consultants even considered planting clerical or custodial…
