[R] Security issue

Hello,

I am trying to convince our IT Manager that R is as safe as possible from IT
security point of view - could you point me to something on the web / some
reasons for why this is true? I do not think he has a specific concern but does
not know the software and would like to understand the security implications.

Thanks in advance

[R] Security issue

Well, of course it isn't true -- no piece of software is 'as safe as 
possible'.  I think some IT managers would prefer not to run any OSes on 
their machines -- now, that is pretty safe (especially if they are then 
switched off to say energy).

You haven't told us your OS -- and that usually means it is Windows (or 
Mac OS). A reasonable question then is 'is R as safe than Windows'. 
However when you start R it says

 	R is free software and comes with ABSOLUTELY NO WARRANTY.

so you are not going to get any warranty about this.  But it seems faintly 
ludicrous to ask if R is safe if you run an unsafe OS -- R is as safe as 
the system calls it uses (and any others you manage to run via exploits, 
although I am unaware of known exploits -- the few reports have been on 
at-the-time obsolete versions of R).  So just don't actually run R in an 
admnistrator account.

But surely that is his job!  Our Computing Manager certainly has it in his 
job description -- and he does allow R on our systems (owned by 
non-administrator accounts).

  To add to Brian's note that rightly says 'R can only do what a user 
can do anyway', I'll point out that R doesn't open any network ports
so
doesn't expose the machine that way. Unless of course you run a network 
server in R (is there a server package on CRAN?).

  I can think of crazy ways where R might be involved in an exploit - 
for example if the malicious party poisoned your DNS, then if you tried 
to install a package from CRAN, a fake DNS entry for cran.r-project.org 
would mean you instead got a package from a malicious party's web site, 
and hence you'd be running the wrong code. It would take a lot of work 
though - I suspect the intersection set of R programmers and black-hat 
hackers is pretty small. And if the hacker can poison the DNS 
effectively then there's plenty of easier exploits to do.

  And anyway, it's probably easier to get malicious R code by just 
announcing it on R-help. A message of "I've written this package to do 
XXYYZ" and a non-CRAN URL might get some people to bite. But the same 
applies to just about anything you download from the net - browser 
extensions, screen savers, add-on applications and so forth.

  R mitigates against this by having open source code for its core and 
CRAN add-on packages. Perhaps your IT Manager should only sanction the 
use of packages from CRAN? Although enforcing this wouldn't be easy.

  So yes, R is as safe as possible, for most values of 'safe' and 
'possible'.

[R] Security issue

Hello Martin,

I can tell you from my experience that quite a few insurance companies in the
London Market use R.
If this is not enough, the following document might help you do find some good
arguments:
