In this first screenshot, I basically opened command prompt and search for ipconfig. Within those instructions, I have gather information that you can evidently see in the screenshot, such as my desktop’s name, wireless LAN adapter, Ethernet adapter LAN, and other connections running. Without typing ipconfig /all in command prompt, people wouldn’t be able to tell a lot from just using a sniffer like Wireshark. For instance, within the content of the screenshot you can tell I have Comcast due to the evidence (hsd1.va.comcast.net) from Connection-specific DNS Suffix. Another thing that can be evidently seen in the screenshot, is my IPv6 and IPv4 address which allows me connect/create more TCP/IP address within the Internet.
Discuss the difference between a physical topology and a logical topology. Why are both necessary? Answer: The difference between a physical topology and a logical topology is that a physical topology applies to how the hardware of the various computers, cables, switches, routers, and other devices in a network fit physically or wirelessly together. A logical topology describes how software controls access to a network and the sharing of its specific resources such as applications and databases. Both a physical and logical topology are necessary to complete the whole of a network’s functionality.
Typically this is handled with a virus scanner, malware scanner, anti-phishing monitor and other tools, each one being individually installed and updated on each computer on the network. With a Security as a Service (SaaS) solution, of which there are many, the in many cases the management of those software resources is moved from the individual machine to the cloud, and in some vendor’s cases, so is the processing for the scans and monitoring. There are also CSPs that offer stress and vulnerability testing of a company’s website on an at-hock or regular basis while others offer DDoS protection and Firewall services. 2. This reading includes information on the potential benefits of using CSPs, and the potential threats of using CSPs.
I will be able to develop the network architecture for various clients and also install, deploy, maintain, troubleshoot product and test services according to their needs. Client requirements may be at local, wide area or an organization level. This will help me to interact with the end user and will help me know their demands. Interaction will be among the users, infrastructure vendors like Internet service providers, software vendors who together make up a communication network and integrate services in them and keep the communication system
This is different from client side scripting however, since to be a server side script the data must be executed on the web server side, compared to the Client side scripts which are executed by the user’s browser. Different Web Server Scripting Languages: There are many different server side scripting languages which can be used on the web servers, these include: ASP: This is Microsoft’s web server scripting product which will commonly only run on a Windows based server. Files have the file extension of .asp which stands for Active Server Pages. Finally VBScript are used within ASP pages. ASP.net: ASP.NET is an open-source server-side web application framework designed for web development to produce dynamic web
Microsoft provides a number of these including for Active Server Page and ASP.NET. Compatibility: Internet Information Services is designed to run on Windows server operating systems. A restricted version that supports one website and a limited number of connections is also supplied with Windows XP Professional. Microsoft has likewise changed the server account that IIS keeps running on. In versions of IIS before 6.0, all the features were run on the System account, permitting exploits to run wild on the system.
Understanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.
Hadoop  is an open source implementation of MapReduce programming model which runs in a distributed environment. Hadoop consists of two core components namely Hadoop Distributed File System (HDFS) and the MapReduce programming with the job management framework. HDFS and MapReduce both follow the master-slave architecture. A Hadoop program (client) submits a job to the MapReduce framework through the jobtracker which is running on the master node. The jobtracker assigns the tasks to the tasktrackers running on many slave nodes or on a cluster of machines.
When designing a DB one should be conscious of the future use of the DB. The DB should be design for new functionality in the future and easy to reuse the design (ALL,2014). Phase 4 of the DBLC(Database Life Cycle) is Implementation. This requires that documentation of the data structure and testing have been evaluated and now ready to install the new system into the organization. Your key players would be the network people who are familiar with the network architecture and design of the organization
Some of the kernel’s tasks are resource allocation, process management, memory management, input/output device management, and security management. It basically mediates access to system resources. The kernel is the vital center of a computer operating system. The service layer acts as a source to resources for application programs such as folder manipulation, input/output device access, starting/stopping programs, and creating, moving, and resizing GUI windows.
Using applocker, you must create rules that enable users to access the files needed for Windows and the system’s installed applications to run. Scenario 6-1 Sophia can create rules that allow this program to run but not allow other programs to run. Scenario 7-1 SmartScreen Filter in Internet explorer 8 has multiple mechanisms for observing sketchy websites. One of these is to analyze web pages for different phrases and patterns that would represent a phishing attempt. This does not use any more bandwidth usage and can be used on company workstations.
1. Goal The objective of this lab was to create a Windows 2012 Datacenter Virtual Machine. On this virtual device, we were tasked with installing DHCP, DNS, and Active Directory services. This was very similar to lab 2 in that all of the core services had to be installed on this one device as with our RHEL7 server previously. This server then, had to be promoted to be the main server for the network.
Or if the user is using windows 7 machine they can launch these resources from the start menu of the local computer like launching a program installed ion the local machine. The Remote Desktop Web Access is previously called as Terminal Service web access. 126.96.36.199 How the RD Web Access works? Administrator publishes the resources (remoteapp, remote desktop session) using Remote Desktop session host server (Refer chapter 3.2). If the user wants to these resources from RD Web Access server then we need to specify the source that provides the RemoteApp programs and Remote desktops .
User authentication in Ubuntu 15.04 systems in an AD environment All HACKD, LLC systems are supposed to be connected to the Microsoft Active Directory domain. However, after implementing Ubuntu 15.04 in the systems that were running on Windows XP, there is a need to ensure interoperability by allowing Ubuntu users to join the AD domain using their credentials. In such instances, the Samba software suite is used to provide AD connectivity and provide stable, secure and fast file sharing and print services to all clients using the SMB/CIFS protocol. In this case, Samba is a critical component for integrating Linux clients in a Windows environment (Samba.org, 2015). However, authentication via Samba is a daunting task since a lot of configurations
