Best Practices for Using R Securely


If you download R (or R packages) using an unencrypted Internet connection, there is a possibility that a malicious actor could modify the code in transit (or substitute their own file), if they have access to the connection linking you and the CRAN server delivering the code. (This is possible, for example, when you download R using an unsecured Wi-Fi network.) This could potentially give an attacker the same rights you have to execute code on your system.

To eliminate the possibility of such an attack, the R Consortium recommends all R users to always download R and R packages using an encrypted HTTPS connection from a secure server. Read about Best Practices for Using R Securely.
