Not many people know or are aware of what a firewall is or how it works. Firewalls are installed onto a computer system as a security system that is making sure that nothing such as a virus gets into your computer, it also controls the incoming and outgoing network traffic based on how the owner sets the settings. Firewalls were first used in the 1980’s it was called a packet filter before actually called a firewall. Firewalls are meant to be installed on a computer so that the computer won’t be hacked. A firewall is the most common security system used in any type of computer. Many people think that a firewall is something simple that once it is installed and applied, then it will work perfectly fine, but in reality a firewall should be properly updated monthly and should get checked on frequently or else it may potentially fail and cause many problems on the device that was affected. Firewalls are not effective enough to protect devices because people can easily hack and are getting passed firewalls therefore there should be something other than firewalls to protect devices. There are many factors on why a firewall is not an effective way to protect personal information. Every year there are new and more advanced technology being made and used, and firewalls are not up to date or are missing many factors that will not keep up with these new and more advanced technologies which make it so much easier for people to get passed a firewall. For example, in Kyle Cebull’s
It offers a secure fitting together between internet browsers and websites, letting you to communicate secretive data online. Physical Layout • Topologies; topology can be measured as a computer-generated nature or construction of a system. This shape does not agree to the real physical plan of the policies on the computer network. • Ring; basically in a ring system each device (workplace, waiter, and copier) is related to two other devices, this systems a ring for the signs to travel around. Each packet of data on the network trips in one way and each device collects each box in turn until the journey 's end device receives it.
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. A network cannot exist without setting up and configuring its hardware and software so that the various parts of the whole work together
It supports family safety settings, which means with the help of this we can keep track of our kids. Like of internet users and we can also make access of certain websites only. In addition to this window 8 also update automatically.
35. Do we run anti-virus software on servers on all Microsoft platforms? 36. Is dial-in access into the system/network is controlled by authentication and logs?
Ensure that our operating system and key system components such as the web browser are fully patched and up to date. 2. Install firewall for each device. Firewall will automatically monitor Internet activities, and will alert you of any problems. Firewalls forbid outside threats such as hackers and viruses from gaining access to your system.
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.
The device is very useful, as whenever any application is run on your device, the user is notified whether it is not secure after the identification is done. It offers a high level of security compared to antivirus programs since it is not vulnerable to credential hijacking and insider tampering. Also, this feature is capable of working virtually, meaning that in any case the OS is compromised in any way, then the Device guard will not be affected in any way but it will continue to work
They hold information about the addresses of computers attached to the network and can forward data efficiently to the correct location via an appropriate route. They are generally used as gateways where a local area network is connected to a larger network such as the internet. Web browsers are software programs that allow a person to explore the Internet in an easy to use way. Navigating the Internet through a series of hyperlinks you can browse the Internet. Examples of popular browsers are Chrome, Internet Explorer, Firefox, Safari, and Opera.
However, there are still concerns about data security, measurement reliability, and the need for reliable Internet
It is defined by RFC 1350. It uses a client-server architecture. After establishing an FTP connection, the user can download or upload files to and from the FTP server. It is a simple version of FTP, lacking some more advanced features FTP offers. It can be used only to send and receive files.
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.
1. Installing antivirus software on all the systems, for example Norton antivirus. 2. Installing antivirus and anti spam software on email servers, examples of antispam software include: 3. Install antivirus and content filter software on firewalls 4.
Software updating If you want to protect your computer from any malicious activities, therefore, you should update your computer security software regularly. It is very important to update a software security software because some weakness software may allow a hacker or viruses to gain access to your computer. Moreover, update a software can able to make your computer faster. If you do not update the security software that means there will be changes to get attacks by hackers and viruses so you should update a security software regularly.
Cybersecurity has become a growing cause for concern in the United States and indeed countries around the world. On February 9, 2016 President Barack Obama announced his Cybersecurity National Action plan (CNAP) to further the nations efforts to protect government agencies, citizens, and businesses from cyber threats domestic and abroad. However, cybersecurity is not a new issue in fact it is as old as the internet itself. With that said, I keep thinking back to that warm September day stained with the image of an enormous fireball engulfing our small TV set. This horrific day changed the course of history forever along with my future career path.
Overview of Immune system The human body provides the ideal environment for the microbes such as bacteria, viruses, parasites and fungi to enter the body. Thus, it is the jobs of the immune system to keep them out by protect the body from the harmful substances. Immune system is when the networks of cells and tissues work together to defend the body against the foreign invaders.(Menche,2012 and National Institute Health,2003). According to the Latin word, immune come from the word immunis which is free or untouched. So it is mean that our body must free from the all pathogens that can lead to the diseases.
