AW: Network Segregation to prevent spread of malware

Hi Tom,
To prevent cross communication VLANs will be an appropriate solution.  If it
has to be on the same network then segregation with firewalls will at least
reduce risk to minimum.

Hi Tom,

The answer is 'it depends', but probably no. If you are talking about a
classic company network and dividing workstations into separate networks to
prevent cross contamination, you have to consider the pivot points for most
malware - email, file shares, etc, which can still allow malware to
propagate between networks even if no traffic is allowed directly between
them. Some kinds of malware, notably worms who propagate directly from one
system to another via some kind of remotely exploitable vulnerability, would
be contained by network segmentation, however those sorts of events are
becoming increasingly rare (however when they do happen, they tend to be big
events).

Hello All,

I need few tips on Network Segregation to prevent spread of Malware. Can I
avoid Malware spreading from one network segment to another just by
segregating network with access list or firewalls?


Thanks,

Tom
