The system helps monitor all the network traffic and helps maintain all the users who are using the network.

A firewall is very beneficial to protect the organisation against any potential malware attacks. Projecting the network is very important, as all the specific data is being transferred through the network only.

As a firewall prevents content filtering and remote access, it is considered an ideal design to protect the network.


8) What do you mean by a traceroute?

A tool designed to help provide the packets with the rightful packet path is known as a traceroute. Traceroute helps provide checkpoints for the packet, which ensures all the points through which the packet should be passed.

The usage of a traceroute is only seen when a packet seems not to reach its destination. Then, check the entire passage to identify connection breakage to prevent the failure of delivery of the package.

We know that when a network or data is transferred, it is usually segmented. All the segment data is then formed into packets that contain different segments of different data.

Traceroute is very beneficial for many organizations, as it ensures proper connectivity of all the different points through which the packet should be passed for transmitting data.


9) What are the differences between HIDS and NIDS?

The primary difference between HIDS and NIDS is based on usage and functionality. HIDS is used for host-based intrusion detection systems. This is a system that helps in the detection of different intrusions.

HIDS is extremely beneficial and functional in monitoring the computing systems and the network packets to help identify a host-based intrusion. NIDS, on the other hand, is the acronym used for network intrusion detection systems.

The NIDS is a very functional part of the organization as it helps identify loopholes where hackers are performing any form of activity.

The primary goal of a network intrusion detection system is to identify different actions that are currently happening over the network and unauthorized activities that are functional in the network.


10) What is the meaning of SSL?

SSL is used for the Secure Sockets Layer. The Secure Socket Locker creates encrypted connections, which are established between the web server and the web browser.

11) What is the basic meaning of "data leakage"?

It might sound very simple, but data leakage is actually the theft of data information through unauthorised sources. A form of cybercrime that is completely related to accepting data and information from the user's device in a very authorised manner.

This is done by attaching malware, where the cybercriminal gains complete access to the user's device and steals all the sensitive data and information. Cybercriminals mostly look forward to weak loopholes on the internet or the network through which they can gain access.

Data leakage is one of the biggest concerns for many users, as it can pose a great threat to both personal and professional lives. Data leakage can happen through email, optical media, and a lot more.


12) What do you mean by "brute force attack," and how can it be prevented?

Every user of the internet has faced a little trouble dealing with the passport at some point in time. The trial-and-error method, which helps find the right password over a particular internet portal, is called a brute force attack.

There are two types of brute force attacks that are used over the internet:

- Firstly, when the user starts entering multiple passwords for their own account to gain access back after forgetting the password.

- The second situation is where cybercriminals continuously collect potential passwords. The second equation is what is considered cybercrime. The hackers use a different combination of alphabets and letters to finally give the right password.

There are many cases in which the user has actually saved their passwords, through which brute force attacks automatically generate or create login passwords for the user. This brute force attack feature is very dysfunctional and can be very dangerous for the user, as the cybercriminal can misuse the data and information from the internet portal.

Brute force attacks can also be prevented. It can be done in three major ways. The first one is by creating a password length. Password length is a very important feature that was created by internet portals to increase the safety of data.

The length of the password plays a very crucial role as it increases the difficulty of getting the password, which the criminal can't guess through the trial and error method. The next episode involves increasing the complexity of the password.

This is done by involving the alphabet, symbols, and letters at the same time. This makes it very difficult for cybercriminals to gain access. The most important feature of a lot of internet bottles to prevent brute force attacks is setting up limitations on login failures.


13) What do you mean by "port scanning"?

Every specific host has a lot of open ports and services that are available over the portal. Port scanning is the only way to identify open ports and services on a specific host. This helps in identifying these places over the specific host.

A lot of hackers actually use port scanning to identify all the information they need to perform criminal activities.

Port scanning can be considered constructive and destructive activities at the same time, as hackers can misuse this technique to identify information for the performance of malicious activities.
