How Does a Ping Flood Attack Work?Ping flood, which is also known as ICMP flood, is a common DoS technique in which an attacker floods a victim's computer with ICMP echo requests, or pings, in order to bring it down.The attack includes sending a large number of request packets to the victim's network, with the expectation that the network will respond with an equal number of reply packets. Another option is to use specialized tools or scripts, such as hping and scapy, to bring down a target with ICMP requests. This puts a burden on the network's incoming and outgoing ... Read More
Many card transactions that would have been done in person can now be done online because of the growing popularity of e-commerce platforms Card-not-present (CNP) payments have risen. As a result, they provide greater convenience for consumers starting the transaction. They require less from retailers, who no longer need to establish a physical location or engage dedicated workers to collect payments. However, the disadvantage of digital modernity is that it makes credit card fraud more common and challenging to detect.What is 3D Secure Authentication?3DS is a security protocol that allows users to be authenticated. This adds an extra degree of ... Read More
The fifth generation of cellular technology is referred to as 5G. The goal is to improve wireless service speed, reduce latency, and boost flexibility. The potential top speed of 5G technology is 20 Gbps, but the highest speed of 4G is just 1 Gbps. Virtualized and software-driven 5G networks make use of cloud technology. With a seamless open roaming capability between cellular and Wi-Fi connectivity, the 5G network will also ease mobility.5G also promises decreased latency, which can help business apps and other digital experiences run better (such as videoconferencing and self driving cars). The time it takes for devices ... Read More
Applications are essential in today's corporate environment because of their importance. Today's applications are more than simply a way to generate money; they're also a vital link between businesses and their consumers — and, unfortunately, a target for hackers. The numbers are startling when it comes to mobile app security.Almost three-quarters of apps would fail even the most basic security checks. At least one security issue exists in 83 percent of apps. Mobile security flaws can be detected in 91 percent of iOS apps and 95 percent of Android apps.Data privacy is critical for every company and individual in today's ... Read More
Internet browsing offers several outstanding features for the user, but at the same time, it comes with its fair share of risks. A considerable proportion of the browsing is done with the help of android smartphones.Recognising whether malware is on the phone is very crucial to protect yourself from it. Malware may be perplexing, interfering with how you regularly use your phone and making you feel anxious, even if you don't know what's causing the issue. It's also relatively frequent. Therefore, we have put together the possible signs of a malware attack on an android in this post.How Does a ... Read More
What is OWASP?OWASP (Open Web Application Security Project) is a non-profit organization dedicated to enhancing software security. OWASP is based on an "open community" approach, allowing anybody to engage in and contribute to projects, events, online conversations, and other activities. OWASP's guiding concept is that all resources and information on its website are free and easily accessible to anyone.OWASP offers a variety of tools, forums, projects, and events, among other things. In a nutshell, OWASP is a one-stop-shop for everything web application security, supported by the collective wisdom and experience of its open community contributors.What are the OWASP Top 10 ...

Credit Card Cracking: What is It?Card cracking is a credit card fraud that makes use of bots (software that runs automated tasks over the Internet). Cracking is founded on the notion that obtaining a credit card number, also known as a Private Account Number (PAN), and the name inscribed on the card is simple. Bots are used by attackers to guess and validate the additional information needed to "break" and use a credit card fraudulently.Criminals can get PANs in a variety of ways −Purchasing PAN listings on the dark webThrough associates who work in retail or restaurants and have access ...

A transistor (or bipolar junction transistor) is a three-terminal, three-layer and two-junction semiconductor device, used as the digital switch and amplifier in the electronic circuits.A transistor consists of three layers of P-type and N-type semiconductor materials and the name of these layers are emitter, base and collector. The three terminals are taken out from these three layers.Based on the arrangement of the semiconductor layers, the transistors are of two types as −NPN TransistorPNP TransistorRead through this article to find out more about NPN transistor (BJT) and PNP transistor and the key differences between them.What is NPN Transistor?An NPN transistor is ...

The directed flow of electrons or charge in an electric circuit is known as electric current. Based on the nature of flow of electrons (or electric current), the electric current is classified into two types: AC (Alternating Current) and DC (Direct Current). Go through this article to find out more about AC and DC and how they are different from each other.What is Alternating Current?AC stands for Alternating Current. The type of electric current whose magnitude changes continuously and direction changes periodically is known as alternating current or AC. In practice, the alternating current is produced by alternating voltage source ... Read More
Multimeters and voltage testers are both testing and measuring devices that are used to measure a wide range of electrical quantities. Go through this article to get a basic understanding of how multimeters and voltage testers work and how exactly they are different from each other.What is a Multimeter?A multimeter is a standard measuring instrument that is used for measuring multiple electrical quantities in an electric circuit. With a typical multimeter, one can measure AC voltage and current, DC voltage and current, resistance, continuity, and other values.Basically, a multimeter is a combination of a DC voltmeter, AC voltmeter, DC ammeter, ...
