This paper is going to be on the different security threats on the internet, and the different ways to prevent and protect yourself from them. The different
threats that are going to be covered are viruses, trojan horses, hackers, spam, corrupt IP packets, port scanner attacks, DOS(denial of service) attacks, spider
attacks, worms and socail attacks. Also, I will cover different security practices and computer software and hardware that can help protect and prevent these
different attacks on your computer, or network. Many people use the words virus, trojan, and worm interchangeably when talking about attacks on their computer,
but in reality, they are different types of attacks, this paper will define and differentiate between the different types of attacks a computer can become a victim of.
A virus is software thats used to infect and damage a computer. The code for the virus is usually imbedded into an existing program so that once the program
that has the virus inbedded into is executed, the virus code activates and copies itself, it then attaches the copies of itself to other existing programs that exist on the
system. Viruses may be simple pranks that just cause messeges to randomly pop up on the screen, but they can also be very damaging to a computer. Viruses tha
damage computers destroy programs and/or data right away when they're activated, or on a certain date. There are some viruses that remain dormant and do its
damage once a year. One example of this type of virus is the Michelangelo virus, a virus that usually only attacks MS-DOS systems, but can cause an equal amount
of damage to other operating sytems, which only infects computers on Michelangelo's birthday. Compute...

...ckets coming into the computer were requested by the user. A firewall can usually examine multiple different layers of the protocol stack, which makes it possible to block packets at any layer or depth. Besides software firewalls, other type of software can protect your computer from viruses, and other types of attacks is antivirus protection. There are many different brands of antivirus protection, but the most popular brands are Norton's Antivirus, and MaCafee. The ways an antivirus program protect your computer is by scanning your computer for viruses and other threats. You can also use your antivirus program to scan files that you download off the internet, or that you transfer from other computers, for viruses. The best way to utilize the protection of an antivirus software is to configure it to perform full-system scans at least once a week.
Hackers have a multitude of tools and techniques to accomplish their goals, and as old tools and techniques become obsolete, new ones are created. Three questions regarding hacker tools and techniques are addressed here. What are the common tools used to conduct a denial of service attack (DoS)? What is a buffer overflow attack, and how does a SQL injection attack take place?
Privacy and security issues have become one of the top concerns among computer users in today’s market. It has become a game of survival of the fittest in protection of your security. The only true way to defend yourself is knowledge. You should prepare your self against hackers, spammers and potential system crashing viruses and web bugs. Lets focus on how you can protect yourselves from the would be thieves.
A computer virus is designed to self-replicate, self-install, and attack the root functions and system of different programs without authorization or the user’s knowledge. Virusesmainly affect the root of a computer system.Virus can destroy and damage most important part of our hard drive, the boot sector, where information about all files has been stored. Viruses may alter directory paths and may change
Trojans are a type of program that can and usually will hurt a PC through software and hardware. The way it gets into the computer is by fooling the computer user into thinking that some software he/she found online is safe. When the person downloads the software, it is not actually useful software. It is actually a Trojan which has now invaded the PC. Once in, it allows the creator of the Trojan to access and control the computer from his own house. The hacker can then access passwords, important documents, and other stuff that will be mentioned later. The malware does not make ...
...ies on other programs for it to continue to spread and often times the same program can be hit by the same virus several times. Cracking these codes and viruses is much harder to figure out. It’s almost like these virus writers make it a puzzle to solve before you can actually disband the virus itself. Even when the code is cracked and disassembled, writers normally just rewrite that code to do the exact same thing again.
The protection of your network requires a level of network security. If you do not have security on your network, then you are capable of being hacked or receiving malware, spy, virus, and lots more. There are many programs or applications that can help detect and prevent strange activities on your computer, but there is also ways that you can help prevent anything from happening. Creating a password for your network is a good start toward protection of your computer. Try to make the password something only you would know, and maybe throw some numbers in there as well to maximize protection. It is good to know who all is on your network and internet; because if someone were to log on to your internet from a distance, they could plant viruses and other things into your files on the network. Quite a bit of problems occur in network when file sharing takes place in a work place to copy or manage files. Most of the time when this happens, no one sets the security setting up themselves,...
Example of a Computer Virus: The Storm Worm is a Trojan horse program. Its payload is another program, though not always the same one. Some versions of the Storm Worm turn computers into zombies or bots. As computers become infected, they become vulnerable to remote control by the person behind the attack. Some hackers use the Storm Worm to create a botnet and use it to send spam mail across the Internet.
In today’s society technology is used for everything. With the invention of computers and the internet this open doors to the cyber world. Today you can do almost anything without having to leave your home. The internet gives us the opportunity of shopping online, ordering food online, working from home and video chatting with friends and family across the world. Everyone has a computer and internet access in their homes. While the internet is really convenient it also opens doors for cybercrimes, loss of privacy and the need for computer security.
“ Prevention is better than cure ”, if computer users are aware of Malware attacks, they may prevent those attacks . So, in this research paper i am going to focus on Malware and Protecting Against Malware.
Conclusion 6. References 3 1. Introduction Internet worms present a solemn threat to todays highly networked computing environment. Unlike other threats viruses and trojans, worms typically scatter automatically without active human intervention, resulting in infection rates that are considerably higher than those of traditional viruses. These Active internet worms spread in an automated fash- ion and can ood the internet in a very short time.
Virus can effect the system. They are pieces of codes created by hacker to create a nuisances and to another extreme corrupt valuable data. Examples of these can be animated icons flying pass the computer screen and to another extreme can be programmes designed to delete the hard drive. The Computer Virus can be caught through a number of ways. The most highly publicised way, is through the Internet, other ways are through removable storage media, such as floppy disks and zip drives. They can also be caught through computer networks, where a third party from another machine in the network introduces the virus (accidental or otherwise) which then spread throughout the network. The most unlikely way of virus contaminating the system is through malicious employees creating them on the system but this will be discussed later on. There are a number of precautions that can be taken to help prevent this. By simply making employees not to use mobile storage media unless they know where it has been, making them aware that pirated media , shareware/freeware programmes may be potentially dangerous. A talk and leaflet distribution to employees could be useful. If the Alsager decides to connect to the Internet, this would be another potential source for virus and such like. A firewall could be placed on the system to help prevent infection. A more immediate way of preventing virus is to subscribe to a antivirus programmes, although this will not give you 100% percent protection it will help prevent the majority of known virus. An important note to this point, is the importance of getting regular virus updates from the software manufacturer.
In fact, according to several studies, more than half of all network attacks are committed internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, and root access attacks.... ... middle of paper ... ...
Virus is one of the most common malware. Unlike spyware, virus is largely designed to harm useful programs or wreck down an entire operating system. There are many ways through which virus may enter a computer. The most common way is via email attachments. A...
What is the “MALWARE”? A malware refers to software programs designed to damage or do other unwanted actions on a computer system. In Spanish, "mal" is a prefix that means "bad," making the term "bad ware" .Malware includes viruses, worms, Trojan horses, and spyware. Viruses, for example, can cause havoc on a computer's hard drive by deleting files or directory information. Spyware can gather data from a user's system without the user knowing it. This can include anything from the Web pages a user visits to personal information, such as credit card numbers.
Malware can survive in a number of ways say different sizes, shapes and also the purpose ranging from viruses to spyware and to bots. Malware in general is classified into two types. They are the concealing malware and infectious malware. In case of infectious malware, the malware code is said to spread all over which means that the software code shall replicate from one user to another and this goes on. In infectious malware, we need to consider two cases, which are called the viruses and the worms. Viruses are termed as the software that has executables within itself and causes the executables to spread when it is run. The second case called worms is a software which infects a computer and then spreads to others.
