Network Security refers to any activities that take place to protect the network; more likely to protect the usability, reliability, integrity, and safety of the network and data. Targeting the threats and stopping them to enter or spread on the network is the job of effective network security. Most common threats for any computer networks are:
• Viruses, worms, and Trojan horses
• Spyware and adware
• Hacker attacks
• Identity theft
• Data interception
To prevent these threats, multiple layers of security need to be implemented so if one fails, other stand. Anti-virus, anti-spyware, firewall are some of the components of network security system used to block unauthorized access to the network and Virtual Private Network (VPNs), to provide

While researching on Windows and UNIX, I found that UNIX has better built-in security and permissions features than Windows (Haas, n.d). While upgrading software from Microsoft, it often requires the user to purchase new or more hardware or prerequisite software, but UNIX on the other hand does not require purchasing (Haas, n.d). UNIX operating system is more stable, faster and more secure compare to windows because most software is written to create damage to windows (Noyes, 2010). In windows if you leave a port open it can be easily used by hacker to introduce a virus in your computer whereas UNIX has to go through various executable permissions that why UNIX is considered more secure than Windows (Noyes, 2010). While windows users are more than UNIX users worldwide, the potential of windows facing security challenge is higher as hacker’s attempts to break the security and viruses built to break in. Thus, users should be cautious at their side to protect their network by regularly scanning the computer against viruses, using firewall and be careful towards identity and data
1.3 How do local area networks (LANs) differ from wide area networks (WANs) and backbone networks (BNs) Local area networks are limited within an organization Wide area networks extend over a large geographical distance and may be privately owned or rented Backbone network are the part of network infrastructure that feeds the connected networks 1.8 Describe the seven layers in the OSI network model and what they do. Application – this layer is specific to applications and provides services such as email, network software services and file transfers Presentation - In this layer, the data is formatted in a schema that network understands, and also manages data encryption and decryption Session – this layer establishes and controls the data communication between
5. METHODOLOGY 5.1 Secure Multipath Routing Protocols in Wireless Sensor Networks Till date many routing protocols have been proposed for wireless sensor networks, but only few of them consider the problem of security [4] and most of them are developed without any security concern. So in this section we focus at selected multipath routing protocols in order to cope with the various attacks. For avoiding intruders attacks in HWSN various methods and algorithms are implemented out of that Professor Hamid Al-Hamadi and Professor Ing-Ray Chen:
Hacking What I would do is record the player hacking and give the proof to a higher official and they would ban the player for 48 hours then the staff will discuss if the player should remain banned or not. If they do not come up with a decision the player would be unbanned after the 48 hour ban they have recieved from an official. But if they do come up with a decision then the player would get a permanent ban. /ban {time} /unban
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.
2.1 AWS Networking AWS provide a kind of networking services that also provide private network connections to the cloud, scalable DNS and tools to make logistically solitary networks. There are also have prevalent networking services comprise the Amazon Virtual Private Cloud (VPC) and Amazon Direct Connect. Amazon VPC generates a logically solitary set of Amazon EC2 for example which can be connected to current network using VPN connection. Amazon VPC generates a private cloud inside AWS, while deposition built-in security with security groups and network access control lists. When using Amazon EC2, VPC is free.
Task1 (3) - comparison of three operating system Components Window 7 Window 8 Ubunutu 12.04 Security It has better firewall. It also support bit locker drive encryption, which encrypt window hard disk to keep documents and passwords as well. Also help to protect desktop against viruses and other malware with Microsoft security essential. It also supports parent’s control which is also an essential part.
Question Set 7 A) What types of methods and tools are used to measure, document and analyze ancient fault activity along the San Andreas Fault and its associated faults? For example, how do geologists determine how long a fault has been active, how often it ruptures, its relative offset motion, and how much offset? Note that the term "ancient" means fault activity that occurred thousands to millions of years ago - long before seismologists were around. Modified Mercalli Intensity Scale: Measures the intensity of an earthquake Richter Scale: Used to measure the magnitude of an earthquake (Tarbuck, 2013)
Getting Started Logging into WorkZone You will access WorkZone at the following URL: https://asu.sharedwork.com 1. A generic WorkZone password will be emailed to you once you’ve been setup as a user in the system. 2. Enter your email address and temporary WorkZone password and select “log in” 3.
Part 1: AUP a) The District AUP is TAUG, and some ways you can’t do or can’t follow is using an account owned by another user or allowing another user, this will result in the suspension or revoking of use of these privileges and may result in legal action being taken against the individual. b) Verbal or written warning, removal of access privileges, removal from computer related classes with loss of credit, suspension or expulsion, legal action, monetary reimbursement and/or termination.
Clear the user history: Erase all the data downloaded by the user once the user log out from the system which will prevent the access of the private data and protects the unauthorized access to the system. 5. Monitor users actions: If a user tries to download data from suspicious website then the administrator should get alert and take the appropriate action. This will help the misuse of the
Virtual Private Network enables you to use internet to connect to machines while making sure that the connections are private. VPN is very convenient, but it is not necessary if you want remote clients to connect to you Linux or Unix server. Many people concerned about fast connections might then ask "how fast can a VPN go?" The simplest answer is that; a VPN can go as fast as other types of connection and can be faster if there is fast internet connection at both ends of the network. Actually VPN servers can be as fast as any other internet connections although there are several things that you should do to have faster VPN internet speeds.
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,
Microsoft Windows is the dominant operating system for personal computers and laptops, with a market share of over 80%. It is widely used by individuals, businesses, and organizations due to its ease of use, compatibility with a large range of software, and support from a vast network of developers. Windows is known for its graphical user interface (GUI) and the ability to run a wide range of applications, from productivity software like Microsoft Office to high-end games. Linux, on the other hand, is a free and open-source operating system that is widely used on servers and other types of computers where stability and security are critical. Linux is known for its reliability, stability, and security, making it an attractive choice for businesses and organizations that require these features.
1:- Penetration Testing It is the process of trying to gain unauthorized access to authorized resources, systems and applications. Penetration testing is also known as an ethical hacking as “breaking into your own system to see how hard it is to do”. Network security measurement is the task which aims at supplying the scanning to check the security flaws and security threats in applications and networks. 2:- Why perform penetration testing • Test network or system using the tools and techniques that attackers use.
However, it also has the ability to take immediate action, such as dropping a specific packet, based on rules established by the network administrator. Antivirus – Software tool that scans multiple points within the network, such as email, file servers, workstations, and mobile devices. Reputation – This is associated with specific file review. Behavioral Analysis – Beyond prevention security layers, there must also be detection layers for a robust network security plan.
