Goal
In this lab the goal was to set GPOs and PSOs for the Windows Server 2012 box that we had set up in the previous lab. Group policies allowed us to manage the settings and configurations on the domain bound machines as well as fine tune the password complexity requirements.
I had already set up multiple GPOs for my machines prior to starting this lab, so all I really had to do was add in any additional GPOs as well as create the Password Setting Objects.

Security Considerations
There are many security concerns that are apparent when looking at this lab and all of the settings that are being pushed out to machines. Some of the most apparent considerations that are touched upon in this lab

This always used to be the way that companies would manage their local admin accounts, however I recently found that this is not the most secure way of handling this process. The reasoning behind this is that the GPO has to be readable to all clients they are pushing to, therefore the hashed password that is pushed to the machine is sitting publically accessible on the DC and can easily be attacked and cracked to reveal the local admin accounts. The proper way that I have found to handle this concern is to use a tool by Microsoft called LAPS.
Auditing
There are a number of different auditing settings that can be put in place that cover a number of different use cases, I will be going over just a few of those use cases.
Initially when diving into auditing, there are some main features that would be beneficial to have. Account logons are very useful to have logs for, for a multitude of different reasons. Tracking which users log onto which computers is beneficial not only for doing troubleshooting, but also for ensuring individuals are not accessing other people’s computers and potentially sensitive
The power spectral densities ($PSD$) of the gas jet centerline $C^*(t)$ for the tests in Tab.\ref{Table} were computed via $FFT$, and collected in Fig.\ref{Spectra}. For plotting purposes, the frequency domain $f_j$ is limited to $f_j=150 Hz$, and the $PSD$ in each graph is normalized with respect to the maximum $PSD$ detected within the three tests. Regardless of the stand-off distance $\hat{Z}$, for $\hat{Y}=0$ the response of the jet to the membrane motion is the superimposition of a harmonic response $f_h$ and a higher frequency $f_f$, which is not affected by the membrane motion. Noteworthy, $f_f$ scales with the standoff distance and leads to a constant Strouhal number $St_Z= f_f Z/U_j\approx 0.08$, not far from the $St_Z=0.12$ \cite{Vshape}
Children in this group were provided with base-10 and unit blocks. Each base 10 block is 1 cm × 1 cm × 10 cm in size. Each unit block is 1 cm × 1 cm × 1 cm in size. The research assistant gave explicit demonstrations of how to use both base-10 block and unit blocks to construct two-digit number. First, the research assistant placed out ten unit-blocks in a line and then put a base-10 block along to the ten unit-blocks.
7.4.1.1 Dielectric withstanding voltage The purpose of this test is to prove that a connector can operate safely at its rated voltage and will be able to withstand momentary over potentials due to switching, surges and other similar phenomena. The applied voltage can be either AC or DC. The voltage should be applied across the two closely spaced contacts as well as between a connector shell and the contacts closest to the shell. The test voltage in the case of coaxial connectors shall be applied between the inner and outer conductor. The voltage should be ramped up uniformly from zero to rated value.
Perhaps many are confused about the existing commands linux, this time I will discuss about the linux basic commands used along with examples of its use. 1: Seeing identification (id and group id number) $ Id 2: Looking the calendar date of the system a. Looking at the current date $ Date b. See calendar $ Cal 9 2002 $ Cal -y 3: Seeing the machine identity $ Hostname
4. OpenVPN—Open VPN is open source and it uses other ope-source technologies like SSL v3/TLSv1 and OpenSSL encryption library protocols. It is not port specific and can be configured on any port. This feature enables OpenSSL VPN traffic indistinguishable from other HTTPS traffic and not easily gets blocked. AES encryption makes it more secure than blowfish encryption.
Lab 7: Moon Phases was designed to measure the relative position of the Sun and Moon over the course of one phase cycle (i.e. one month, 29.5 days) The idea for Lab 7: Moon Phases was to examine how the illumination of the moon by the Sun produces the different phase cycles we see as the Moon rotates around Earth and as the Earth rotates around the Sun. The observations of the Moon were taken on four different days in the month of February to March capturing four different Moon Phases.
Osk.exe not working error in windows 8 must not be ignored and this is because the file remains responsible for Accessibility On-Screen Keyboard in Windows Systems. In fact, the error which is generated is primarily in the numerical data format. It is important that you take steps to rectify the same as many annoying error message pop-ups might be generated and slow down your PC considerably. Further, there remains ample scope for system freeze and blue screen of death (BSOD) issues happening as well.
All data that is transmitted over a network is open to being monitored. One way to create a more secure environment would be to restrict file permissions. It is usually recommended that file permissions are set so that only necessary access is granted. Another way to create a more secure environment would be to use secure passwords to verify the user’s identity. Password security is very important when it comes to protecting not only the network, but the user and workstation.
HTTP & TCP Input & Output In this simple java program, I inputted an HTTP URL for a website, and when the program is run, it returns HTTP data for the specified website. In terms of TCP/IP model, this HTTP request would fit under the application layer, as I am using an interface to exchange data through a network. More specifically, as the data exchange is utilizing the HTTP protocol, and sends the data through port 80. Here, I am using a very simple java TCP server and client.
The focus of this section, will be collection and analysis of the data for the two RQs. First, I will state the needed data for each RQ, potential sources and process of analyzing it. For instance, estimation of desertified area or ESAs (Environmentally Sensitivity Areas) (11) for each year –1994, 2004 and 2014 – will be based on four indicators (NDVI, Albedo, Soil moisture and Sand dunes). The selection of these indicators based on many studies. For instance, the selection of the best indicators to monitor and assess the desertification in arid and semiarid region seen a lot of evolution.
1. Goal The primary purpose of this lab was to get familiar with RLES and establish a base infrastructure. This infrastructure includes a router/firewall and Linux server for network monitoring and documentation. Network monitoring is crucial in any infrastructure, no matter how small or how large.
37. Are all our email servers configured to check all incoming and outgoing emails for viruses, spam and other threats? 38. Are only authorised staff can access operating system utilities and perform software upgrade and administration to network components? 39.
Group Policy Objects (GPOs): Security settings on workstations and for users should be uniformly applied across all company devices, and should not be modifiable by users. Microsoft Active Directory allows an administrator to set numerous configurations and settings that can be applied on all workstations and user accounts. If it is configurable in Windows, it can be managed by a Group Policy Object (GPO). Any company policy that requires a specific setting, should be enforced by creating a GPO that forces user and workstation compliance. For example, if the Password Policy requires users to choose a password of a specific length and complexity, a GPO can be set that enforces that requirement
First of all, I read the reading topics assigned in the "Learning Guide Unit 1" particularly the Boolean functions, Boolean algebra, different types of logic gates and its composition, truth table, etc. However, I followed all of the reading topics assigned. Apart from the reading topics, I also go through the video lectures. Then after, I attempted "Self-Quiz Unit 1", completed "Unit 1 Assignment" related to creating different types of Logic gates. Finally, took part on the "Discussion Forum Unit 1", commented on three colleagues' post, and graded them.
1. Standards Driven Data: Online tools and resources will be used to analyze standards used in a course. How often are they being used and are they being used appropriately? Data then will determine what needs changed and adapted to meet those requirements. 2.
