Different Types of Computer Attacks

| December 8, 2011 | 0 Comments

Pressures build from the hackers and computer programmers in this technological age are more volatile than ever before. In the computer industry, it is imperative need for the users to constantly update the information of computer attacks and viruses, to prevent their systems and keep their data safe. Users demand the more secure environment, while the technological changes in the computer world presents both the new opportunities and threats.

In the fast footed technological age, industry is facing now numerous types of computer threats. Personal computers and the network systems, needs the more secure environment to protect their data. There are some viruses and attacks that have an adverse effect on the computer and may corrupt the data, whereas, in some of the cases, the data could be stolen, while in other cases, the entire network could be encountered by the attack.

Types of Computer Attacks:

Today, to cope with the dynamic approach of computer attacks, users are adjusting to face the challenges of new threats.
So, first, let’s take a brief look at the types of computer attacks, what effect they can cause and their harmful consequences on the data and networks. Generally, there are two types of computer attacks.

1- Passive attacks:  In the passive kind of attacks the content and data stream is observed and then utilized in future for the malicious purposes.

2- Active Attacks:  In particular, active attacks cause the change or permanent loss of data or destroy the entire network.

To give an idea, given below are the most popular types of active and passive attacks that cause the major threats to computer users.

Active Computer Attacks:

Virus: Users need to be more prudent with the computer viruses, the most popular form of computer attacks. They are constituted of computer malware programs, which can cause a lot of damage to the content and other operations of computer system. They have a significant tendency to automatically install into the computer via executable program or through an external hard drives, email attachments or through the various internet sites and spread across immediately into the data files on the systems. Once they have successfully executed onto the computer, they can lead to a major cause of damage and spread across to other connected systems and networks.

Root Kit: Root kit is amongst the most hazardous computer attacks, it provides the administrator level privileges to the hackers through a set of programs. The attacker gets the full access to the private data and system files of the computer or the network associated with the user. They can cause a lot of damage than the normal computer attacks; intruder can obtain or steal any of the secure information and also can take control of the computer.

Trojan: Similar to the viruses, Trojan horses is a form of malware. It is a hidden network software application, which generally utilized by the hackers for the malicious purposes. It works as a transmitter of viruses and root kits, to damage the private data or the network system. They can cause the major harm to the security system of personal computer or a network.

Worm: Computer worms are the malicious executable applications, just like the viruses. It is a self reproducing malware executable program which infects the data without any assistance. They spread across the network connections independently and inadvertently, exploit the security and operations of the computer system.

Passive Computer Attacks:

Eavesdropping: Eavesdropping is a network attack, the intruder capture and read the data content or any confidential information, transmitted between two computers on the network. Hackers can access the transmitted data by damaging the intrinsic secrecy of network connections, over the internet and in a closed system, by using the network sniffers tools.

Password Based Attacks: Most of the existing cyber attacks are password based attacks, with adversaries that could gain the access of the computer and network resources. An intuitive approach of password based attacks is to get the password access and then change, delete or amend the network configurations and get the secure data and pass on to the other channels.

Denial of Service Attack: Denial of Service Attack targets the computer system over a network or personal computer and ceases the functionality of system. In this case, user will be deprived of the services and information. Attackers can interrupt the services in a number of ways, by crashing the services or by transmitting the variant packets of protocols to obstruct the communication services between the users.

Compromised Key Attack: In compromised key attacks, attacker gets the secret code which is called a compromised key to encrypt or to validate the secret data. Attacker transmits the information with the associated servers, to decrypt, change or delete the sensitive data. Moreover, the attacker can also get the access to other sensitive and secure information by using various permutation and combination keys.

Identify Spoofing: The attacker gains the unauthorized access over a network or a computer system by utilizing the IP address. In order to get the privileges, attacker sends the various IP packets to the target IP, after getting the privileges; hacker can remove, delete, amend or steal the information on the system. This type of attacks, corrupt the transmission of data stream and attacker can damage the other associated system within or outside the network by using the hacked IP addresses.

Application Layer Attack: These types of attacks deliberately target the server’s operating system and applications. Once the damage has occurred, intruder can bypass the access control and can easily get the controls over the server’s applications, system, data and other associated users. This could also leads to the termination of operating system and applications, data could be hacked, deleted or modified and security controls could also be disabled permanently.

These are some of the common types of computer attacks, which have an adverse effect on the individual and network security systems. In general, with the advances in information technology, computer attacks will continue to increase, day by day. That is why you need to have good anti-virus software installed into your PC so that you can continue your online work or business dealings with no fear of these viruses at all. So what are you waiting for? Just go online and read reviews about popular antivirus softwares like AVG vs Avast or AVG vs WebRoot to choose the best one for the excellent security of your online system.
