Nt1330 Unit 3 Assignment 1 Computer Virus

My identity is wrapped up in my love of music because I have been surrounded by it since I was little. When I was a toddler, I would sit for long periods of time and watch videos of kids singing songs. As I grew older I participated in my church's children's choir and even held solos in my elementary school chorus. When I reached middle school I joined my school's middle school chorus in 7th grade as an alto and 8th grade as a soprano. The transition between 8th and 9th grade was important for me because I took up voice lesson in 8th grade and went to my first music camp the summer before 9th grade.

Others ways to protect a computer from virus are: if you don’t know the sender of a message with an attachment, don’t open it; back up your files often to keep your data safe from virus; use routers and firewalls to monitor your computer activity and block unauthorized entries; disable macro security settings in working with Word or Excel to prevent running without permission.

Hi Friends! I am describing here about the Newstarads.com which I have faced some days ago in my computer system. I am just explaining here that what are the real malicious works of this virus when it attacks into your PC.

This can help delete all the malware or malicious content on the computer’s system. This can be the only way to save a computer at times, for example if the memory storage has been filled up with worms that keep copying themselves until the system stops responding. If this is the case then deleting everything can be the easiest way to stop. Other times, the malware is not visible to the user allowing it to travel through the system’s hard drive and damage the files. It can also be disguised as useful files.

This unique characters, otherwise called signatures can be a byte pattern in the virus. This is usually done using the AV software, the AV software uses the signature obtained from the signature database to detect the malware, and when a match is gotten, the AV software then alerts and prompts the user to repair or remove the file. - - Heuristic-based Detection: unlike the signature based detection, the heuristic-based detection is mainly designed to detect previously undetected or unknown viruses. Heuristics based detection detect viruses based on how they behave; that is to say the heuristic blocks the action of a file that it’s not behaving the way it is known to behave using sandbox techniques from a heuristic scanner.. - - SQL (Structured Query Language) Injection is when malicious attackers make use of SQL statements to interact with a database.

In order to do hardening system on any type of software computer you would have to look at the type of location that your network is going to be installed in after you fine or survey the following location then you would definitely get a location to where you would like to place your hardware to install your firewall systems once you get the physical aspect of your file systems installed you would then have to look at how setting up the software passwords on most computers or on your security system on the network then you would not stop there because you would have to keep access controls established on the location to make sure that physical security of the location does not hinder anyone from trying to get into the location that has authorized

Reading assignment number three is important because of the rapid growth in technology. The reading assignment touches on the subject of using visual imagery and learning how to properly analyze what we have seen. Analyzed properly a picture can tell the viewer many things. Visual imagery is becoming a more progressive.

1) $250,000 or $500,000 (MFJ) gain exclusion on sale of principal residence as long as the ownership and use test have been met.

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. When creating a password it must be complex enough to not be guessed easily. It is believed that strong passwords they are based on length and being random. When creating a password you should use the following:

I have been asked to use Ubuntu? One comparison between windows and linux is that Linux is a lot freer than windows because windows are restricted. Another comparison is windows are a lot safer because if something breaks you get paid support whereas on Linux you do not have any support. My experience with Linux is not much as I am entirely a windows user.

To ensure the wireless signal is transmitted to every corner of the office space I recommend routers set-up with 4 directional antennas and a centralized Omni-directional antenna. The use of 2.4 GHz routers will increase data transmission speed 460-600 Mbps and provide 11 channels per router to support decrease in network collisions and prevent data packet from being dropped (Lazar, n.d.). All computing devices must be equipped with latest Windows 10 for business and use VPN tunnels to remotely connect and send print jobs to the Austin location. In addition, all workstations must manually be configured with the latest printer drivers to recognize the device.

Part 1: It would effect everything on the planet, plants would be less able to produce the suns energy and living organisms would be in big trouble. A short term effect would be decreasing plant populations and a long term effect would be a decreasing population of every organism on the planet. i. Much like the first one, if the sun was completely blocked producers could not produce, thus consumers could not eat them and get energy and the decompress could not break down the organisms if they're not alive. It would result in the overall extinction of living organisms on earth. ii.
