Random numbers are the numbers which play an essential role for various network security applications. There are some approaches that are used to generating random numbers including pseudorandom number generator and linear congruent generator also cryptographically generated random numbers etc.The main objective of the Chinese Reminder Theorem is to generating Random numbers. In essence, CRT says it is applicable to reconstruct integers in a certain range from their residues modulo a set of pair wise relatively prime modulo.CRT is one of the main theorems of mathematics. This can be utilized in the area of cryptography. It is a perfect set ... Read More
What is a DoS attack?A denial-of-service attack is a type of cyber-attack where the perpetrator tries to make a network resource unavailable to its intended users by stopping the services of a host connected to the Internet for a certain length of time or indefinitely. Denial of service is often accomplished by flooding a targeted computer or resource with unnecessary requests that could cause systems to become overburdened, preventing any or all genuine requests from being fulfilled.In a distributed denial-of-service (DDoS) attack, the incoming traffic flooding the target comes from various places. This renders stopping the attack by just preventing ... Read More
Fermat's little theorem is a fundamental theorem in elementary number theory, which provides compute powers of integers modulo prime numbers. It is a specific case of Euler's theorem, and is essential in applications of elementary number theory, such as primality testing and public-key cryptography. This is referred to as Fermat’s little theorem.Fermat’s theorem is also called a Fermat’s little theorem defines that is P is prime and ‘a’ is a positive integer not divisible by P then −aP−1 ≡ 1 mod PSecond condition says that if P is a prime and a is an integer then aP ≡ 1 mod ...

Computer WormA worm is a harmful software (virus) that repeats itself as it moves from computer to computer, leaving copies of itself in each computer's memory. A worm finds a computer's vulnerability and spreads like an illness throughout its associated network, constantly looking for new holes. Worms, like viruses, are spread by email attachments from seemingly trustworthy senders. Worms then propagate through a user's email account and address book to contacts.Some worms reproduce and then go dormant, while others inflict harm. The worm's code is referred to as payload in such circumstances.How do they work?Computer worms make use of network ... Read More
While face-to-face human interaction appears less common, we are more likely to communicate with our technology. Machines are starting to respond, from Siri to Alexa. Now, businesses recognize the value of Chatbot services and implement them into their networks, resulting in a more efficient and user-friendly consumer experience across many platforms. With its rising popularity, so does the concern of chatbot security; let us see more on the threats of using a chatbot is and what precisely a chatbot does.What is a chatbot?A chatbot is a computer with artificial intelligence (AI) that uses critical pre-calculated user phrases and auditory or ...

What Is SIEM (Security Incident and Event Management)?The process of finding, monitoring, recording, and evaluating security events or incidents in a real- time IT environment is known as security incident and event management (SIEM). It delivers a centralized and comprehensive picture of an IT infrastructure's security situation.Security information event management is another term for security incidents and event management.Software, systems, appliances, or a combination of these components are used to deploy SIEM. There are six major characteristics of a SIEM system in general −Retention − Keeping data for a long time so that more full data sets can make judgments.Dashboards − A tool ... Read More
Security researchers discovered multiple vulnerabilities earlier this year that affect practically every PC, laptop, and smartphone on the market. The flaws, known as Spectre and Meltdown, are found in the design of modern CPUs and allow personal data (passwords, e-mail, and surfing history) to be accessed from memory by exploiting Speculative Execution and Branch Prediction capabilities. The features are performance-enhancing technologies that enable processors to pre-execute instructions and forecast future execution routes.The Meltdown vulnerability is thought to be very simple to cure. Still, due to the nature of Speculative Execution, we will most likely have to settle with mitigation in ... Read More
AES encryption defines the phase of hiding electronic information using an approved 128-bit, 192-bit, or 256-bit symmetric encryption algorithm from the Advanced Encryption Standard (AES), also called a FIPS 197.In the 1990s, the US Government required to standardize a cryptographic algorithm which was to be used globally by them. It is known as the Advance Encryption Standard (AES).Several proposols were submitted and after multiple debate, an algorithm known as Rijndael was accepted. Rijandael was invented by Joan Daemen and Vincent Rijmen. The need for appearing up with a new algorithm was actually because of recognized weakness in DES.The 56-bit keys ... Read More
Maybe you're thinking of uninstalling a VPN subscription and giving up security. We can assist you with this, but we believe it is equally important to remind you of the dangers of exposing yourself online. Fortunately, uninstalling a VPN is a straightforward procedure. Certain VPNs, on the other hand, have been known to leave behind logs or records of your activities, either in the system files or in the registry. We'll teach you how to get rid of them if you stick with us.Ctrl + Shift + Esc is a combination of the keys Ctrl + Shift + Esc.You should ... Read More
Have you ever had the strangest sense that someone was watching you while you were working on your laptop? Well, you may be paranoid, but there's a good probability that your computer's camera has been hijacked. Isn't it terrifying?A laptop camera is an important computer accessory that may be used in a variety of ways. It does, however, constitute the most significant threat to your privacy. If someone gains control of your laptop camera, they can use it to spy on you, with well-documented repercussions.Some experts have even said that the fight on privacy has already been won by consumers. ...
