DNS Spoofing is a type of computer attack wherein a user is forced to navigate to a fake website disguised to look like a real one, with the intention of diverting traffic or stealing credentials of the users. Spoofing attacks can go on for a long period of time without being detected and can cause serious security issues.
Cipher is an algorithm which is applied to plain text to get ciphertext. It is the unreadable output of an encryption algorithm. The term "cipher" is sometimes used as an alternative term for ciphertext. Ciphertext is not understandable until it has been converted into plain text using a key. Description: Earlier cipher algorithms were performed manually and were entirely different from modern al. A computer worm is a malicious, self-replicating software program popularly termed as 'malware' which affects the functions of software and hardware programs.
Description: It fits the description of a computer virus in many ways. For example, it can also self-replicate itself and spread across networks. That is why worms are often referred to as viruses also. But computer worms are different fr. Description: The term 'computer virus' was first formally defined by Fred Cohen in Computer viruses never occur naturally. They are always induced by people. Once created and released, however, their diffusion is not directly under human control.
Denial-Of-Service DoS is an attack targeted at depriving legitimate users from online services. It is done by flooding the network or server with useless and invalid authentication requests which eventually brings the whole network down, resulting in no connectivity. As a result of this, users are prevented from using a service.
Description: A DoS attack is initiated by sending needless and sup. Memory corruption can be described as the vulnerability that may occur in a computer system when its memory is altered without an explicit assignment. The contents of a memory location are modified due to programming errors which enable attackers to execute an arbitrary code. It is one of the proble. Trojan or Trojan horse is the name given to a computer virus. It is a type of computer software that is camouflaged in the form of regular software such as utilities, games and sometimes even antivirus programs.
Software terminologies can be confusing. Developers integrate strong authentication and authorization processes to secure their application from malicious actors. It determines the right of a user to access resources such as services, data servers, networks, databases, files, etc.
Most applications feature a login page where users have to enter their credentials to prove their identity. Those credentials may consist of their user ID, username, email, or phone number and the password associated with it.
There are several ways to perform authentication, including one-time passwords, biometrics, authentication apps, hardware tokens, software tokens, and many others. One of the most common ways for authentication is passwords - if a user enters the correct password, the system checks the credentials and grants access to the user.
However, passwords are often targeted by hackers and are vulnerable to cyberattacks , such as brute force attacks, data breaches, man-in-the-middle attacks, and password cracking. In multi-factor authentication, the system may require the successful verification of more than one factor before granting access to the user. Once a user is authenticated, the application knows who you are. Authorization then is determining what that user can do within the application vertical authorization, e.
Authorization is the process of giving necessary privileges to the user to access specific resources such as files, databases, locations, funds, files, information, almost anything within an application. For instance, you might want to allow administrators to view sensitive information but limit third-party suppliers from accessing this sensitive data.
Authorization is often used interchangeably with user access control and user privilege. When it comes to authorization, you can take different approaches to it. For example, once you log in to your email account, you can view all of your emails, reply to them, delete them, categorize them, modify your personal information, and do other email-related tasks.
However, if a user wishes to perform a particularly sensitive operation, they might need to take additional steps to authorize the request. For instance, if a user is trying to make a payment, they might have to re-enter their password, or repeat the authentication process, to validate their identity again. In secure environments, some applications might use such precautionary authorization methods if they observe unusual user behavior, like an IP address, or an unusual time of login, or an attempt to make a high-value transaction.
