What is SNORT?
In the area of cybersecurity, the requirement for robust and effective intrusion detection and prevention systems is critical. SNORT, a network intrusion detection and prevention system that is free and open-source, is one of the most well-known and commonly used systems in this area. Snort, which also notifies system administrators of potential security concerns. Martin Roesch created it for the first time in 1998, and since then it has grown to be one of the most popular network security tools worldwide. What is SNORT? The initial version of SNORT, an open-source network intrusion detection and prevention system, was made available ...
Read MoreWhat are the Top exploited vulnerabilities of 2023?
Introduction Within the ever-evolving scene of cybersecurity, remaining educated approximately the most recent vulnerabilities and abuses is significant. As innovation progresses, so do the strategies utilized by cybercriminals to breach frameworks and compromise delicate information. The year 2023 has seen its reasonable share of vulnerabilities that have been misused by noxious actors. In this article, we are going dig into a few of the best-abused vulnerabilities of 2023, shedding light on the potential dangers they posture and the measures that can be taken to relieve them. Exploited Vulnerabilities of 2023 ChatGPT This vulnerability was distributed in Walk 2023 with a ...
Read MoreIoT edge computing and data sustainability
By now, you must have gotten a clear picture of IoT and how it is aiding us by making our lives easier. IoT connects sensor devices and the internet for those new to this technology. These devices have sensors that collect the data and send it to the cloud over the internet. Now in the cloud, all the data processing happens. In simpler terms, sensors collect data and send it to the data centre, where it will be analyzed, and commands sent back to sensors. The entire process takes time, and processes are delayed. But then, how do we come ...
Read MoreDifference between Internet and World Wide Web
Many people get confused when they think about the two terms internet and WWW. They use these terms as a replacement for the other. But both are not same and in this article, we will discuss about the difference between the Internet and WWW. What is the Internet? The internet is being used by billions of users all over the world to search data, play games, watch movies, listen to songs, and do a lot of other things. The internet is a network in which a lot of computers are interconnected to each other. People can communicate with each other ...
Read MoreIntroduction to Host Names: Understanding the Basics
In the world of computers and the internet, host names are a critical component of how devices connect to each other. A host name is a unique identifier that is assigned to a device or a server on a network. It is used to identify and locate devices on the internet or any other network. What is a Host Name? A host name is a label that is assigned to a device on a network. It is used to identify and locate devices on the internet or any other network. A host name is made up of a combination of ...
Read MoreWhat is hierarchical routing?
In hierarchical routing, the routers are divided into regions. Each router has complete details about how to route packets to destinations within its own region. But it does not have any idea about the internal structure of other regions.As we know, in both LS and DV algorithms, every router needs to save some information about other routers. When network size is growing, the number of routers in the network will increase. Therefore, the size of routing table increases, then routers cannot handle network traffic as efficiently. To overcome this problem we are using hierarchical routing.In hierarchical routing, routers are classified ...
Read MoreWhat are guided and unguided transmission media?
In transmission media is the way the systems are connected to route data signals in a network.The telecommunication links are classified into two categories −Guided media (wired)Unguided media (wireless).Both guided and unguided are used for short distance (LANs, MANs) as well as long distance (WANs) communication.Let us discuss Guided transmission media.Guided transmission mediaGuided transmission media consists of physical connection between source and destination through a wire or a cable.There are three basic types of guided media which are as follows −Twisted pair cableCo-axial cableFiber-optic cableTwisted Pair CopperStep 1 − It is the most used media across the world. All the ...
Read MoreClassful Vs Classless Addressing
Classful AddressThe first addressing system to be implemented as part of the Internet Protocol was Classful Addressing. In the year 1981, the Classful addressing network architecture was first used on the Internet. The Classful addressing system was superseded by a Classless addressing scheme with the introduction of Classless Inter-Domain Routing (CIDR) in 1993.The IP address comprises up of 32 bits and is split into four sections separated by dots: part 1, part 2, part 3, and part 4.The IP address is made up of four parts, each of which is eight bits long (1 byte).Further, the 4 parts of the ...
Read MoreDifference between Circuit Switching and Packet Switching
Circuit SwitchingCircuit Switching is a connection-oriented service. It provides a dedicated path from the sender to the receiver. In-circuit switching, a connection setup is required to send and receive data. It has very little chance of data loss and error due to the dedicated circuit, but a lot of bandwidth is wasted because the same path cannot be used by other senders during a congestion. Circuit switching is completely transparent; the sender and receiver can use any bit rate format or framing method.Advantages of Circuit SwitchingIt uses a fixed bandwidth.A dedicated communication channel increases the quality of communication.Data is transmitted ...
Read MoreNetwork Devices (Hub, Repeater, Bridge, Switch, Router, Gateways and Brouter)
Network devices or networking hardware are the physical devices that are used for establishing connections and facilating interaction between different devices in a computer network. Hub Hubs work in the physical layer of the OSI model. A hub is a device for connecting multiple Ethernet devices and making them act as a single network segment. It has multiple inputs and output ports in which a signal introduced at the input of any port appears at the output of every port except the original incoming port. A hub can be used with both digital and analog data. Hubs do not perform ...
