Unit 3 Assignment 1: Choosing Port Scanning Software

In order to test server security your Senior Administrator has assigned you to run port scanning software to analyze servers and security. Search the Internet for and choose port scanning software to implement on your network.

Questions:

1. What is port scanning?
Answer: The act of systematically scanning a computer's ports. Since a port is a place where information goes into and out of a computer, port scanning identifies open doors to a computer. Port scanning has legitimate uses in managing networks, but port scanning also can be malicious in nature if someone is looking for a weakened access point to break into your computer. (Webopedia, 2013) 2. What is the goal of port scanning?
Answer:
a. To determine services that a computer is running and shut down services not being used to increase the security of the computer being scanned. b. To determine the vulnerabilities of the services that is being run in the computer being scanned. The vulnerabilities can then be patched once they are identified.

3. Would you prefer an open source or proprietary port scanning software?
Answer:
Many people in the business world prefer to use proprietary software instead of open source software due to the misconception that proprietary software is better supported than open source software. After several years of supporting both open source software and proprietary software, it becomes clearly evident that just because you pay for proprietary software does not mean that supporting that software is any easier; in fact, there are plenty of reasons why supporting open source software is actually easier. (Mandelbaum, 2012)

4. What port scanning software would you recommend to your Senior Administrator? Explain why.
Answer:
Perhaps the best known port scanner is NMAP. The NMAP command can be used to find all open ports on a range of IP addresses.

Port Scanning

...Unit 3 Assignment 1 Choosing Port Scanning Software NT2670, James Fairchild 1. What is Port Scanning? Is a software application designed to probe a server or host for open ports. This is often used by administrators to verify security policies of their networks and by attackers to identify running services on a host with the view to compromise it. 2. What is the goal of Port Scanning? The results of a scan on a port is usually generalized into one of three categories, Open or accepted: The host sent a reply indicating that a service is listening on the port. Closed or denied or not listening: the host sent a reply indicating that connections will be denied to a port. Filtered, dropped or blocked no reply from the host. Open ports present two vulnerabilities of which administrators must be wary, Security and stability concerns associated with the programs responsible for delivering the service- open ports. Security and stability concerns associated with the operating system that is running on the host. Open or closed ports. 3. Would you prefer an open source or proprietary port scanning software? Depending on who you ask? Many people in business prefer to use proprietary software instead of open source software, due to the misconception that proprietary software is better supported than open source. After several years of supporting both open source and proprietary software it becomes clearly evident that just because you pay for proprietary software does not mean...

Chap 3 Summary

...devices use ‘ports’ to connect to either internal or external hardware to and from the computer. The ports are then linked to copper circuits and memory that communicate to the computer CPU, RAM and ports. This enables data transfer between these I/O devices and the computer. Nowadays, the Universal Serial Bus (USB) port is considered to be the most important I/O port among all other I/O ports because it has replaced PS/2 (mini DIN) mouse and keyboard, serial (COM), and parallel (LPT) ports in recent computer systems and providing greater speed. A recent computer desktop system has at least four USB ports and can support up to eight front-and-rear mounted USB ports. The three standard types of USB ports are (1) USB 1.1, (2) USB 2.0 a.k.a Hi-Speed USB -and (3) USB 3.0 a.k.a Superspeed USB and use either Series A a.k.a Type A or Series B a.k.a Type B types of connectors. Adding more USB ports can be done by using motherboard connectors for USB header cables, hubs and add-on cards. Serial (COM) I/O ports also known as RS-232 ports are used for external modems, serial mouse, plotters, label printers, serial printers, PDA docking stations, digital cameras and PC-to-PC connections used by file transfer programs such as DirectCable Connection, LapLink and Interlink. These ports come in two forms: DB-9M (male) and DB 25M (male) but only the former is not being used for older systems. This I/O port requires two hardware resources: Interrupt ReQuest (IRQ) and I/O port address. Parallel...

Inventory Management Systems

...Inventory Management Systems Inventory Management Systems In the past inventories where done manually. An innovative business owner today will use an automated system to keep track of their inventory. This system would keep track of the products that support the business mission. “Before the Industrial Revolution, merchants basically had to write down all of the products they sold every day (Inventory Systems Blog, R. Lockard, 2012).” Automated inventory management systems would be advantageous to both the business owner and their customers. For the business the products can be monitored for their types, quantity, price, availability, cost, and trends. For the customer, reliability of the business to provide the latest trends, stock on hand, and price. In order to help my sister in creating an automated inventory system, converting from her manual inventory to an automated system on a small budget, would be to create a plan to identify what is needed. “Cost justification is the process of determining the return on a productivity investment. The savings are measured and evaluated relative to the cost of the system, in present value terms (Systems ID Warehouse, 2006).” The first would be to identify all aspects of the project for instance creating a list of the equipment, maintenance, and cost.

...Learning Zone Management Structures (Relevant to Paper 2: Business Communication and Organization and Management) Sebastian A. Bombaci, CPA Introduction When a new employee joins a company one of the first things they learn is the company’s management structure. This includes understanding the working relationships with their manager, subordinates and peer group. Management structures appear in every type of organization including government departments, nongovernment organizations (NGOs), charities, and even the local sporting association. Choosing the correct management structure ensures an organization’s continued growth, content employees and profitable returns for the shareholders. Choosing the wrong structure creates tensions between employees and managers, allows inefficient work practices to flourish and reduces company profitability. In the worst case an incorrect management structure can lead to company closure. Unfortunately, many managers take it for granted that their organization’s management structure is correct, static and never requires changing. However, such assumptions are naïve and as the pace of change increases, there is a need to continually assess the suitability of a company’s management structure. A very topical example of an inappropriate management structure is that of the American automobile manufacturers. A combination of out-dated management structures, inefficient business processes, poor work-place relationships...

Introduction Today's business applications are more complex and time-critical than ever before. Adaptability and multi-tasking have become more than just industry buzzwords in recent years, and nowhere are they more necessary than in warehouse operations. The ability to efficiently identify, receive, store, retrieve and ship goods and materials is critical to the overall health of a company. Complicating this task is a shrinking labor pool of skilled workers and an influx of workers for whom English is not their first language. Increasingly, companies are recognizing that voice-based solutions offer significant benefits for a number of warehouse applications and help warehouse workforces to rapidly become more efficient and productive in their day-to-day operations, regardless of their skill level or language spoken. Voice solutions recognize spoken words as data entry and provide audio (verbal) directions and confirmations to workers. For the non-technical operator, voice is the easiest and most transparent of all data entry and order picking technologies available. In fact, voice has been called the most natural and intuitive of all data entry methods since it's one of the first skills we learn. Voice Overview Voice solutions leave a worker's hands...
