o Introduction:
Computer is an important device, used by people to satisfy their own needs, whether those needs were for studies, business, or entertainment. This is why when it comes to network security, it can be considered as a big issue. This report will provide its readers with detailed summary about some network threats, such as Spyware, Malware and DoS. And some ways to help preventing these threats, using Firewall and NAT.
What is spyware?
With many types of software that are spread around the internet intended to do harm, it is quite important to take caution when it comes what spyware can do much of harm. Spyware is a term that is used to describe software that performs specific actions, but without getting your permission before using it, such as:
• Advertising.
• Collecting personal information of different people.
• Changing your computer configuration.
Spyware is often related to software that shows advertisements (often named adware) or at other times it is software that follows the trails of personal information.
Trading tracking for services
What said before doesn’t mean that all software that use ads or software that keeps track of your online activities is bad. For example, let’s say you signed up for a free music service, but by that it means that you are paying for the service by agreeing to get the targeted ads. If you fully understood the terms you agreed to, you may by that have decided that is a fair tradeoff between the two of you.
If the observation sequence’s ALL lies within this confidence interval, then it will be considered as botnet communication. 3.4 EXPERIMENTAL RESULTS Using the experimental setup, Spyeye, Blackenergy, Zeus, Athena and Andromeda botnets are installed. Zeus, ZeuS, or Zbot is a Trojan horse malware package that runs on versions of Microsoft Windows. While it can be used to carry out many malicious and criminal tasks, it is often used to steal banking information by man-in-the-browser keystroke logging and form grabbing.
Exercises #3: There are many classification methods that can be used with IDPS’s systems. The main point of this system is to detect hostile actions. The first classification is based on the place where ID systems can be placed and the second one is based on analysis of the technique used. These ID systems can be classified into three main groups starting with Host Based Intrusion Detection System (HIPS), then Network Behavior Analysis (NBA), Network Based Intrusion Detection System (NIPS), and Wireless Intrusion Prevention System (WIPS). The WIPS it analysis the traffic of wireless network, NBA examines traffic to identify threats that generate unusual traffic flow, HIPS monitor single host for suspicious activity, NIPS it analyzes the traffic of entire network.
In this section of the presentation I will be talking about anti-virus, the first one I will be talking about is firewall this is a software or a hardware based system that is made to block access from a network. This is used in most network as a line of defence to try and stop bad packets entering the network and cause harm to the network. How it does is this by filter all the suspicious packets that can harm the network . There are three different types of firewalls proxy firewall, packet filtering firewall, stateful Firewall, I will start of with the stateful inspection packet filtering firewall, this is basically the eye of the network as it tracks on everything out and in the network, so if somehow the hacker enter the network and damage it because
With widespread use of internet services, the network scale is expanding on daily basis and as the network scale increases so will the scale of security threats which can be applied to system connected to the network. Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders.
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,
With ads constantly streaming, music playing, or news updates processing, no one has the chance to think on their own. The feed is obnoxious and can overload a person. Corporations are constantly bombarding them with advertisements, music, and news. It is the way business make money, they try to get people to buy items they are streaming, and the more someone buys the more of an investment they are to that corporation. The corporations try to make the ads so enticing people feel like they have to have it.
Many times a reader will be browsing the web and see pop-up ads that apply to a website they recently were on. This shifts the reader's attention from the site they are on, onto the ad itself.
Many advertisements have all different types of purposes, especially ones that
The recent revelations about the NSA surveillance programme have cause concern and outrage by citizens and politicians across the world. What has been missing, though, is any extended discussion of why the government wants the surveillance and on what basis is it authorised. For many commentators surveillance is wrong and it cannot be justified. Some commentators have argued that surveillance is intrinsic to the nature of government and its ability to deliver the public good.[1] Few, though have looked at the surveillance within a wider context to understand how it developed. A notable exception is the work by Steven Aftergood.
Intruder Detection system It is a type of security software which is identifying the malicious activities and later on, it finds the person who is trying to do malicious activity. For example, an insubordinate employee gives all information about a customer to another company without permission which is illegal. Also, he shows his dishonesty to his company. Therefore, the intruder detection system will be able to protect the information.
The Undercover Parent, Argumentative Essay In Harlan Cobens article “The Undercover Parent”(2008) he gives many examples that can help you decide if parents should use spyware on their child or not. I agree with coben, because I feel if you know what your child's doing you can keep them from making the wrong choices. One of my examples to support my position is the article when coben says “you shouldn't monitor to find if your daughter's friend has a crush on kevin next door.
In conclusion, advertisement is propaganda with deleterious effects on our society. Often times we don’t even know we are being affected- this is because advertising is so common. A child may see an ad twice, but they will remember the tones or images and begin to want that toy or product they see. An adult may see an ad that relates to them and a desire for the product, they never wanted to begin with, is
It dont mean you should stop using it. The web can be at good thing if you just use it for the right reasons. But the one thing i´m asking you to do, is to be careful and take care of each other on the internet. But also, have fun. (Modern digital technology is a blessing and the only way forward)
The following section will consider advantages and limitation of the first two mentioned types of digital forensics: Traditional (dead) and Live computer forensics. TRADITIONAL (DEAD) VS LIVE DIGITAL FORENSICS Traditional (Dead) Forensics In order forensic acquisition to be more reliable it must be performed on computers that have been powered off. This type of forensics is known as ‘traditional’ or 'dead ' forensic acquisition. The whole process of dead acquisition, including search and seizure flowchart and acquisition of digital evidence flowchart is shown on Figure 2 and Figure 3 respectively.
There are two main types of broadband connection, a fixed line or its mobile alternative. Both have their strengths and potential weaknesses so you need to consider what suits your needs before you sign up on a lengthy contract. Fixed line broadband is what most people have at home. It 's a fast internet connection delivered by telephone wire (ADSL) or fibre optic cable. As the latter is now capable of speeds in excess of 100Mb, an increasing number of homes have "superfast" fibre optic connections.
