RStudio IDE (or RStudio) is an integrated development environment for R, a programming language for statistical computing and graphics. It is available in two formats: RStudio Desktop is a regular desktop application while RStudio Server runs on a remote server and allows accessing RStudio using a web browser .
Two-factor authentication is a 'strong authentication' method, as it adds another layer of security to the password reset process. In most cases this consists of Preference Based Authentication plus a second form of physical authentication (using something the user possesses, i.e. Smartcards, USB tokens, etc.).
The seed is different for each token, and is loaded into the corresponding RSA SecurID server (RSA Authentication Manager, formerly ACE/Server [1]) as the tokens are purchased. [2] On-demand tokens are also available, which provide a tokencode via email or SMS delivery, eliminating the need to provision a token to the user.
TOTP credentials are also based on a shared secret known to both the client and the server, creating multiple locations from which a secret can be stolen. An attacker with access to this shared secret could generate new, valid TOTP codes at will. This can be a particular problem if the attacker breaches a large authentication database. [4]
MasterCard SecureCode uses OTAC to confirm a user's identity One time authorization code as used in Yammer's desktop client. A one-time password (OTP), also known as a one-time PIN, one-time passcode, one-time authorization code (OTAC) or dynamic password, is a password that is valid for only one login session or transaction, on a computer system or other digital device.
Tokens can be duplicated without special privilege, for example to create a new token with lower levels of access rights to restrict the access of a launched application. An access token is used by Windows when a process or thread tries to interact with objects that have security descriptors ( securable objects ). [ 1 ]
However, some such systems, such as RSA's SecurID, allow the user to re-synchronize the server with the token, sometimes by entering several consecutive passcodes. Most also cannot have replaceable batteries and only last up to 5 years before having to be replaced – so there is an additional cost. [ 3 ]
R is a programming language for statistical computing and data visualization.It has been adopted in the fields of data mining, bioinformatics and data analysis. [9]The core R language is augmented by a large number of extension packages, containing reusable code, documentation, and sample data.
