Firewall is program which prevent unauthorized access to network system. Firewall works as a blockade through which the traffic goes either of the direction must pass. A firewall gives you a single chokepoint through which all incoming and outgoing Internet traffic must pass, allowing you to control traffic. Firewall technology was first emerged in late 1980 's when internet was a new technology in terms of connectivity, globally.
It 's found as both software solution and as a hardware appliance the difference is that hardware firewall acts as a DHCP server to the network where as many Personal Computer operating system have built-in software firewalls to protect user against virus. Threats from public server
ARE THERE ANY DISADVANTAGE OF NOT HAVING A FIREWALL:-
Yes, there are plenty of disadvantages of not having a firewall. if someone using a computer or having a small network one must follow threat by hackers who can hack their computer data /network quiet easily there are plenty others ways they get infected some of them are: -PC get infected from VIRUS,WORM,TROJAN etc. within in no time even if you installed fresh window it will get infected.
-Theft or disclosure of Personal data
-Interception of data
-etc.
These are some causes of not having a firewall protection in PC HOW FIREWALL PROTECT PC:-
Most firewall specially built-in firewall alerts the users when some suspicious action happens in computer. Any hacker want to access

However, they can get the issues resolved with the help of different online tools as well as by some basic troubleshooting steps that are commonly practiced. However, these tools and steps can solve the issues only when the problems are elementary.
This would have a big impact to an even bigger untapped consumer base, allowing CanGo to market better. ● Being able to operate online gives the CanGo company new potential customers from all over the world to view and purchase their products. Threats ● New competitors pop up every day ● Reaching more customers means more work and the staff would be asked to juggle more. ● The lack of a strategic business plan hurts being that it would make things difficult for CanGo to work on defining long and short-term goals. ● Communication ● CanGo could run risk of outside suppliers having tech issues.
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
Network Monitoring Management I definitely feel that Linux and Windows machines provide very different sets of traits that work better for different things. Linux is clearly the more easily secured server as it allows a lot more granular control of every piece of the operating system and the data that is housed there. Also, being completely open source, it allows for a lot more options for software as well as control over every aspect of the system. Windows, on the other hand, has what I feel is a lot more developed approach to managing users, groups, and machines.
Assignment-7 Group Policies Group Policies: Group policies specifies settings for users and computers which includes security settings, software installation, computer startup and shut down, registry based policy settings and folder redirection. Group policies are responsible for controlling the working environment of users and computers accounts. It provides the configuration and management of the user’s settings, operating system and applications in a working environment. It is responsible for the user’s actions in a computer like what a user can and cannot do on the computer for example enforce users to have a complex password to prevent the network from being accessed by unidentified users. Group policies when properly planned and implemented
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.
Other, methods such as anti-virus software can detect threats but do not always remove them successfully. It is also necessary to do disk formatting when changing the operating system. For example updating from Windows 7 to Windows 10. This makes it work with only the files that it needs.
Disadvantages are that you may have to pay for the antivirus software after it runs out. Usability and Accessibility Using the Kaspersky software is very easy, you just run the CD and then install it onto your software and then follow the instructions, its fairly straight- forward. Once you install the software you must update it every now and again but then a notification will pop up telling you to update it. Clean up tools
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.
Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.
In this leaflets I will be talking about how the network can be attacked, One way the network can be attacked is DOS and what this stands for is Denial of service, this attacks the network by overflowing the network with useless traffic, the result of this overflowing cause the network to slow down significantly, and even can crash the network if it overflows too much. The damage that is can do to a business is huge they can lose a lot of money to fix the issue. The weird thing is that the hacker does not even benefit from this attack. The second way the network can be attacked is backdoor this attack is basically when you can access a computer program that side-steps security, the hackers use backdoors that they made or backdoors they found,
In addition, the Computer Misuse Act 1990 recognises following offences, which leads to new offences of unauthorized access with the intention of committing a crime. This can lead to a person being guilty of causing a computer to perform any intent of having the secure access of any program/data held in the computer they are accessing.
Software routines will handle traffic that is coming in from different sources and that will choose where it will end up. Towards the end it will work out where it need to go and which devices will take the data. Also devices and software such as for interface card for the device driver. This is allowing the data to handle incoming packets from various locations and it select the last place it travels to. Error handling and diagnostics is when a device is allowed to access a network layer locally.
This is great from an automation and security standpoint. If you have 500 employees but 200 of them use a specific level of security to access data sets and administrative processes but the other 300 are basic agents providing general guidance and customer support- you can set up permissions and programs based on the user location and allow or disallow communications and privileges regarding programs and access to webpages. A downside to this is that generally you need a specific operating system to run and manage this type of network. However, with the extra money and steps to create and use, you have a higher customization rate to where you can determine exactly in real time what is happening on the system and make changes with minimal
Encryption Security: Hard drive encryption: Without hard drive encryption if a hard drive becomes lost all the information on the hard drive would be viewable by plugging it into another computer. Particularly with a peer to peer network all the other computers on the network will be available if the hacker can access one. Wireless encryption: Wireless encryption is not as secure as a physical network, especially; if that wireless encryption is going to be the main way that strangers will be connecting to the network. All wireless protocols need to be at least WPA2 because of how many tools are out there and older models can be cracked.
