Subject: Retina scans caused broadcast storms
Has anyone ever caused a full blown broadcast storm by using
the Retina Security Scanner.
No, but it is possible with any scanner, depending on what
you are scanning and what port scanning options/ranges you
have set in Retina (or Nessus or Foundscan or whatever). Some
older network gear and *nixes will respond pretty happily to
everyone with a bit of probing.
Also, if you have fed Retina windows auth credentials and
told it to do full log-on NTLM scans, and you also have
speed set to '5', you are 100% guaranteed to see a performance
impact on systems. Slower workstations may see a significant
performance impact in application responsiveness and network
connectivity.
This can be avoided by using a less aggressive configuration.
Retina pretty much does what you tell it to.
