If we intend to study computer science and we have the objective of knowing absolutely everything about this type of career, it is important that we know the most specialized terms. For example, we must know what a sniffer is, an application focused on computer networks that is used daily by professionals and that has great relevance in the technology sector.
Definition and initial concept
We start with a simple definition that allows us to understand what the nature of the wifi sniffer is and later we will see in depth what it is used for. These types of applications have the responsibility of making the capture of different packages that are in circulation through a computer network. The application is not limited to capturing the packets indiscriminately, but has the ability to analyze the topology of the network and carry out the capture taking this factor into account.
In addition to this, sniffers have a fundamental use, which is to analyze the packets of the network and study them, not just capture them. Because of this there are many experts, not only those who have good intentions, who use sniffers with the intention of obtaining valuable information from the different packages that, are traveling through the network.
The process of operating the sniffer is less cumbersome than the definition of this type of application itself may seem. The tool, used by the network managers, analyzes all the packets and the data that is sent. Analyzes and reports are obtained from which specific information is obtained, as is the case of the sender of the information, the recipient of the information, the server that deals with the process and the type of data packet that is being transmitted.
This data is more valuable than it may seem at first glance, given that with the appropriate sniffer can provide us with very detailed information that could even transcribe a chat conversation in full. Therefore, although sniffers do not have to be a factor of concern, they can end up being dependent on how data packets are accessed.
What do we use the sniffers for?
The sniffers have the bad reputation of being used in a habitual way by computer hackers and by people who do not have good intentions in the access to the data that get these applications. But it is not the only type of public that takes advantage of them. For example, there are responsible for networks in companies or on a personal basis that use sniffers in a completely legal way to carry out actions that can be very beneficial in their work.
One of the tasks that can be done with sniffers is the management of everything that happens within the LAN network that has been organized in a specific company. The computer will have full control over the network and there will be nothing that escapes him.
With the sniffers you can also do complete audits of the networks, check the traffic entering and leaving the company and monitor based on it the behavior of it.
Another good point of support is to take advantage of sniffers as a way to become a possible hacker who intends to attack the networks of the company in which we work. By doing this we will check the vulnerabilities that exist in the networks themselves and we can move on to the protection phase so that none of this happens again. With this we can avoid any type of threat of industrial espionage that threatens us and reinforce security levels and each of the actions carried out by users within the company.
When carrying out the identification of the packages that circulate through the network that is administered by the professional in charge of the supervision of the same, they can be aware of everything that happens and know how to act in each case. This applies regardless of the type of network in question, since it may not be that of a company, but that of an educational institution or a home where there are several users connected.
