Unit 2 – Assignment 1: Selecting Security Countermeasures Marcial Norori IS3220 Mr. Sebastian Burci ITT Technical Institute – Hialeah, FL. 1/5/2015 A secure Web server provides a protected foundation for hosting Web applications. A Web server configuration plays a critical role in the Web application's security. Badly configured directories can lead to unauthorized access. A forgotten detail can provide a convenient back door, while an overlooked port can be an attacker's front door.
Which of the following is the most likely reason why EMI from one wire does not affect the electrical behavior of another wire inside the same cable? b 7. Which of the following facts are in common between both of the Ethernet standards discussed in this chapter, 10BASE-T and 100BASE-T? (Choose two answers.) a,b 8.
Thank you! Junior Admin Dear Jr Administrator: * Check the event log for relevant messages. Possible errors can be problems with the KCC in constructing the topology, problems from the SMTP service (SMTP-SVC) in delivering the mail, problems from the ISM service in reading the messages, or problems from the NTDS in decoding and applying the mail. * Verify that the KCC setup is on SMTP-based connections between the servers in the sites you want. This indicates that the site links are what you expect.
We could bring up the case as a sample to demonstrate what we are discussing about. However, adding a question to prove our point is not recommended in academic writing. The subject line information to identify the situation has to be included on the head of the memo. In addition, clarity, correctness, and courtesy are very important and they represent for our efforts. The memo should be clearly written and organized in direct order, beginning with the objective and then systematically and covering the vital bits of information (Rentz, 2008).
Professor Babcock NT1310 April 3, 2015 Unit 3 Assignment 1 Hierarchical Star Topology Hierarchical network topology is similar to the C: drive on your windows PC. This has a central root node which is at the top with a point to point link between each node on down. As you may have noticed this means it acts as a hierarchy with there being a main node and then it branches down from there. One of the best things about this type of topology is that fault identification is easy. This network can be expanded by the addition of secondary nodes.
In effect, we have application-level multiprogramming within a single process. While this multiprogramming can result in a significant speedup of the application, there are applications that would benefit from the ability to execute portions of code simultaneously. 4.8 Define jacketing. The purpose of jacketing is to convert a blocking system call into a non-blocking system call. For example, instead of directly calling a system I/O routine, a thread calls an application-level I/O jacket routine.
Under large bussiness corporations, the scope expands to include other factors such as safe-guarding business legal and transactional interests. The integral part of AUP is the cde of conduct the the users need to display when using the internet or internet. Code of conduct stipulates that the users have to what extent to use the network, the language that uses when they are online especially on social sites and avoid illegal activities that the organisations doesn’t allow. The company or the organisation offering internet have the consequences on the violation of AUP. This may include
• Imagine you are a CISO of a publically traded company and concerned about security when sending any message traffic over the Internet to your remote sites. Determine the security measures you would consider implementing to mitigate security risks when sending message traffic over the Internet. Explain your reasoning. Teardrop – a mangled packet sent in fragments via overlapping or overloading payloads which could cause the systems as it has in the past with older OS versions. Sequence number – hijacked or interrupted TCP/IP sessions via injected packets that disguises its origination from one of the two computers in a session.

Discuss one to two (1-2) ways in which a company uses management information systems in order to increase organizational efficiency and productivity. Explain the overall manner in which the four (4) building blocks (i.e., input devices, CPU, main memory, and output devices) of a computer
