Threat modeling should be carried more often because new threats emerge now and then. This process should be iterative and should begin during the early design phases of an application and go on throughout the life cycle application. This is due to two reasons. The...

NETWORK SECURITY DA-1 Registration Number:16BCI0095 What are Network security protocols? Protocols are a set of rules governs the communications between two sources. Network security protocols are a type network protocol that ensures the security and integrity of data in transit over a network connection. Network...

The seven-layer OSI stands for Open Systems Interconnect reference model is a reparation of the way data travels through a network, it is an international standard for communication, the ISO reference model is divided into seven different layers, these are the application, the presentation, the...

A local area network (LAN) is a network that connects computers and other devices in a relatively small area, typically a single building or a group of buildings. Most LANs connect workstations and personal computers and enable users to access data and devices (e.g., printers...

The next generation of wireless is in process and is causing a lot of excitement; 5G networking, also known as fifth generation of cellular networking, is expected to provide higher bandwidth and data rates, with fewer transmission delays. Currently the technology is in the planning...

Authentication Attackers can try to gain access to sensitive data and services. Access control limits is one of the way to secure the sensitive data. It give limitations to users who or what can use specific resources as well as the services or options available...

5G technologies are a new paradigm supported by the European Commission (EC) to overcome the challenges of next-generation networks. Extraordinary high speeds and capacity, multi-tenancy, fixed and wireless access network are only a few examples of the complex demands that 5G aims to undertake. The...

Without security measures and protocols that have been set in place, certain data can be exposed to attack. Certain attacks are “passive”, which translates to the data being observed; other attacks can be active, implying that the data is changed with the intention of corrupting...

In old days, pirates were the group of people who perform series of criminal activities on a boat or ship over the sea area. For instance, let’s look at the history: how we learn cyber security from the real pirates story. In 1522, three people...

A switch is an intermediary device which is used to connect multiple end devices within a local area network to share information and also to connect them to network routers to forward information to another network. There are different types of switches’ form factors available...

A network is a collection of computers, servers, mainframes, network devices and peripherals connected to one another to allow the sharing of data. Below are some of the commonly used network devices. Bridge A network bridge joins two different computer networks using the same protocol...

Common Types of Network Attacks: Eavesdropping At the point when an attacker is eavesdropping on your communication, it is alluded to as sniffing or snooping. The capacity of an eavesdropper to monitor the system is for the most part the greatest security issue that executives...

Security Threats of WLAN With the growing deployment of WLANs, e.g. in a business environment, the risk of unethical data interceptions increases significantly.Setting up a rogue access pointA rogue access point (AP) is a unknown wireless AP that has been installed on a secured network...

When using a dial-up remote access server on a private network the user is easily able to connect directly to the network. By using a VPN, the connection is internet based, and the user connects to an Internet Service Provider from a modem to a...

OSPFv3 supports different types of areas depending on the requirements of a network. These areas are: Normal Area: Normal area also referred to as regular area connects to the backbone area via one or more area border routers. The link state advertisement (LSA) types that...

Hacker often describer as who uses their ability to gain...

Sometimes when you try to log in to a wireless network, you experience an authentication error. This is a common problem that is faced by many tablet and Android smartphone users. What is annoying is the fact that this error pops up even if you...

Virtual private network (VPN) is not a fully safe and secure as well as guaranteed technology. However, It also has some issues or problems behind it. Actually VPNs are not perfect and it has some limitations exist. In VPN environment such as IPsec, it is...

DoS assaults have turned out to be progressively famous, as they have turned out to be greatly simple to dispatch. Individuals with just a direct level of specialized aptitude can rapidly utilize an overwhelming assault against a person’s webWebsite or a whole company’s. The final...

Today, organizations face the challenge of protecting data in more places including the cloud, mobile, emerging platforms, and legacy applications. And the volume and velocity is also increasing. The bad news is that organizations of all verticals and sizes are being hit with data breaches....

Abstract: The network infrastructure of any organization is always under constant threat to a variety of attacks; namely, break-ins, security breach or system misuse. The Network Intrusion Detection System (NIDS) employed in a network detects such penetration attacks and intrusions within a network. Known classes...

One of the initial signs of degradation of a concrete surface is cracks. Cracks may develop in the walls of the building due to many reasons such as seasonal changes and poor quality of materials. In this research both image processing techniques as well as...

Priya Ranjan Muduli et al. (2013) have identified a crack detection method in which they have combined two of the methods and the methods were Hyperbolic Tangent filtering and Canny edge detection algorithm. They have also used Haar Discrete Wavelet Transform Algorithm (HDWT) in which...

The median-filter algorithms also have some limitations. Hwang and Haddad et al. (1995) indicated that the median filter performs quite well, but it falters when the probability of impulse noise occurrence becomes high. In their study, the median-filter algorithm was used in the second selection...
