As wireless and mobile technologies continue to grow in presence and popularity, the world is becoming more and more connected. Unfortunately, this also means that devices and networks are becoming more and more vulnerable to outside threats. Businesses must identify and mitigate these vulnerabilities and threats in order to protect employees’ personal information and ensure the organization is secure from passive leaking of proprietary information.

 

In this task you will assume the role of an IT professional who is responsible for identifying wireless and mobile vulnerabilities, as outlined in the scenario below. You will then present your findings and recommend solutions to mitigate these risks and prevent future threats.

SCENARIO
You are a network professional on the IT team at Alliah Company, a new but fast-growing social media provider. One year ago, Alliah launched a social media website aimed at young professionals. The company also released a mobile app for accessing the site from cellular devices. Alliah was able to launch its website with money generated by a crowd-funded campaign, but most of the funds were spent on the site and app development, with relatively little money (and time) devoted to the internal office network infrastructure.

 

Alliah has 35 full-time employees, all of whom have offices or shared work spaces in a three-story building that serves as the company headquarters. The building is an old warehouse that was converted for office use and is approximately 10,000 square feet. Currently, the employees occupy only two floors; the third floor is vacant and available for expansion.

 

The Alliah WLAN has a gigabit managed switch, a multiservice wireless LAN controller, and seven wireless access points strategically located to provide coverage to office staff. One access point services a large back patio area for employee use. The network is protected by a firewall. The Alliah website servers are located in a data center 100 miles from Alliah headquarters.

 

Five employees are account representatives who are on the road at least 80 percent of the time, and each rep has a company-issued laptop, tablet, and smartphone. They use a large, shared office in the headquarters building when they are not traveling.

 

Employees use company-owned computers that connect to the WLAN, and, in an effort to control costs during the launch, Alliah has a bring your own device (BYOD) policy.

 

The IT staff consists of five employees; three are devoted to website maintenance, one manages the headquarters’ computers and network, and another employee assists with the website and the office network. IT staff uses wired Ethernet connections to remotely access the website servers.

 

The Alliah website is successful, attracting more and more visitors each month. Jennifer, the CEO, anticipates hiring more employees and is considering a strategy that would take the company public within a few years. In preparation, she wants to ensure that Alliah’s wireless networking infrastructure is highly secure, especially because it may need to grow quickly in a short period of time, and she wants to understand the security risks the company faces. She also wants to decide if Alliah should continue allowing BYOD or restrict network access to company-owned devices only, or if a compromise solution is available.

A. Describe two WLAN vulnerabilities that present risks for Alliah, based on the details in the scenario.

B. Describe two mobile vulnerabilities that present risks for Alliah, based on the details in the scenario.

C. Summarize the steps for mitigating each identified WLAN and mobile vulnerability, including the specific tools or documentation that will be needed for mitigation.

D. Recommend preventive measures to maintain the security posture of WLAN and mobile environments in a small business, such as Alliah. Reference federal, state, or industry regulations that justify these measures.

 

 

Sample Solution

She then started to send him invitations every day, and he became accustomed to visiting her every evening. He later described her to his
Désirée Artôt
brother Modest as possessing \”exquisite gesture, grace of movement, and artistic poise\”.
He had put aside his work on his symphonic poem Fatum in order to give her all his attention. It seems plausible that Tchaikovsky was more captivated in her as a singer and actor than as a romantic interest, and had difficulty in separating the artist from the person. Tchaikovsky dedicated his Romance in F minor for piano, Op. 5, to her.
By the end of the year, marriage was being considered. It has been said that this was Tchaikovsky’s first serious attempt to conquer his homosexuality. Her mother, who was traveling with her, opposed the marriage and she married a Spanish baritone.
Though his personal life may have been unsuccessful, Tchaikovsky was steadily completing composition after composition. In 1875, Tchaikovsky\’s world premiere of his third symphony was given in Boston on October 25, and was conducted by Hans von Bulow. Despite there being pockets of opposition towards his music, his works and reputation began to spread across Europe.
In 1877, he married a beautiful young woman named Anotonina Miliukova, but divorced her 9 weeks later.
Nadeshda von Meck
During the same year of his disastrous marriage, Tchaikovsky also entered into another relationship – only instead of meeting face to face, they communicated through letters. This worked out very well for him given his extreme shyness, and also in part, he did not have to consummate the relationship.
The woman was Nadeshda von Meck, the widow of a railway magnate who had begun contact with him not long before the marriage with Miliukova. As well as an important friend and emotional support, she also became his patroness for the next 13 years, which allowed him to focus exclusively on composition.
