5 Leading Network Attacks, Security Threats And Their Effective Resolution

By Author: Brooke Perry

Most of us know and understand major threats to our PCs, network and other mobile devices connected to the web very well. In common parlance, network attack refers to security incident that are further classified as an impending threat, denial of service, PC security intrusion and others. In this article you will get information regarding 5 most recurring network attacks.

Below discussed are the 5 latest networks attacks faced by the users:

Spoofing

In this article spoofing refers to the identity spoofing of IP address. All Internet connected devices send data packets into the concerned network in order to connect to the network. These data packets contain information such as IP address of the sender and application layer data. Because of this it becomes dangerous for the PC user if the attacker acquires control of the software that are run on a network device. Once the attacker acquires the control, he can easily make changes in the protocol of the device that enables them to place an arbitrary IP address into the data packet. This entire process adopted by attackers is known as IP spoofing.

Sniffing

Sniffing or packet sniffing refers to the data packet interception that impedes a network. Sniffers programs are designed and executed to work at Ethernet layer through network interface cards. These programs aim to impede all the web traffic that travel to and from the host site. These sniffer programs are so dangerous that they can pick up all the communications packets that are found near the internet host site.

Eavesdropping (Mapping)

It is the usual behavior of attackers to acquire information regarding IP address of machines on a particular network, the operating system (OS) and other offered services, before making attack. Using such information they make the attack more precise, focused and well-oriented. This process of acquiring information about the target PC is known as mapping or eavesdropping.

Usually most of the network communication takes place in clear text or unsecured format that creates an opportunity for attackers to get easy access to data paths in the network that enables them to interrupt the traffic. The eavesdropping on your communications is generally referred as sniffing or snooping. It is one of the biggest security threats faced by administrators in any enterprise.

Password attack

Password attack is another common network security threat that aims to harm your documents and files. The attacker tries to decode the password in a bid to steal or harm files and documents stored in a password protected network. Technically there are three diffrent types of password attacks which include:

Dictionary attack
Brute-force attack
Hybrid attack

The most dreadful of these three is the dictionary attack that employs a word list file containing a list of potential passwords for executing attack. Moreover, the brute-force attack employs a combination of characters for cracking password.

Phishing Attack

Phishing is a potentially dangerous network attack that is in practice these days. While conducting this type of attack, the hacker usually employs a fake web site that looks almost similar to the target website which is mostly very popular. The site may be of any leading bank or financial institution. Sending e-mails to the target website is also the part of the strategy. The attackers make the user into clicking on a link that leads him to the fake website. The moment user tries to log on to his account, the hacker records the username and password that is later used to access the respective account on the real site.

Above discussed are the 5 leading network and security threats you should be cautious about. These threats can creep into your PC anytime while you are using Internet network therefore it is always essential be protected with antivirus or antimalware programs when you go online. You should also employ the basic online security mechanism because it helps you prevent majority of the threats and ensure your security.
