In terms of cybersecurity, the federal government would really like to get its hands on some of
the data that ISPs like Tata has on many of the threats out there from major botnets, malware and
different attacks taking place. You have that kind of data, don't you?
Yes. Technology has increased over the last couple of years and there are watchdog organizations
that actually have a pretty good idea on who the bad guys are and where they're going and where
it's coming from. These watchdog organizations, leverage the realities of the network against these
bad people. Their bad traffic, in terms of DDoS, botnets or other malicious activity has to route
across the Internet. It has to have a source and a destination address. The way that most of the
bot variants communicate is hard coded within the bot code so they have a pretty good idea of where
these things are talking to and the ports and signatures that are associated with it. I'm not
speaking for Tata specifically, but generally the technology exists for any Tier-1 ISP to listen in
and sample their core and paint a pretty complete picture on not only malicious traffic that might
be transiting their network, but also certainly stuff that is originating or terminating within the
network. That technology is not prohibitively expensive and because it's based on flow data,
there's a really good chance that it's not going to violate too many privacy laws either, because
it's really just looking at the outside of the envelope.

The experts I've talked to say malware isn't getting more sophisticated, it's the amount of
malware being detected. Some experts are pointing to automatic tools enabling more of these kinds
of attacks. Do you agree with that?
Yes I agree. Since I've been in the network security business for just about as long as there's
been a network security business, there hasn't been any kind of new news in the approach in
combating [malware]. It's always about the reliance on people to patch their computer, have the
antivirus and pay attention to things. These bots infect millions and millions of residential PCs
that are not necessarily part of organizations that have the resources or the expertise to make
sure that the remediation steps occur. It's so damn easy to do. The cost to get into the [malware]
business is reasonably low. It's a zero-risk enterprise and since there's money involved, there's
really no future that I could see, if things continue the way they are, that this is going to be
less of a problem. It's damn near free to get into the botnet business, you're almost certainly not
going to go to jail over it and if you spend the time and build your bots up, you can make a
descent living doing it. We're not moving away from a global network. In the short time that the
Internet has been up and running, our global economy has moved squarely into the global
network.
You participated in a recent cybersecurity study from the Center for Strategic and International
Studies (CSIS) and McAfee that surveyed CISOs about the state
of critical infrastructure globally. Was there anything that stood out to you in that
report?
When the final paper was published, there were no big surprises to me. The reason for that, in my
opinion, is that Tata Communications, when it comes to gauging the threat landscape, we rate risks
to our companies and our critical infrastructure more along risks to revenue. Obviously we,
especially in this economy, have limited resources that we can bring to bare to do the physical
security at our facilities, but when we make decisions on where to put those resources, we tend to
do it more with an eye on risk to revenue. If we have a large cable landing facility that is
terminating lots and lots of STM-1 circuits, we see that as a higher priority facility than an
outlying facility that does not carry as much traffic. Our whole risk model tends to be based more
around revenue, because we are a business whereas the federal government is in the position of not
owning any of the infrastructure, but also their threat landscape is more of a strategic national
interest. They see the aggregate of many cable landing facilities that provide your transpacific
and transatlantic and even your terrestrial Internet backbone in America. They see that as a larger
animal. They don't look at just one or two utilities, they look at all of the utilities as critical
infrastructure. That threat surface for them and that equation is different for the government.
When we try to determine risk we look at the threat, the consequence of that threat being
exercised, but we also have to look at the probability of it occurring. After the attacks in Mumbai
last year, we have facilities that were right within that danger area and the terrorists literally
walked right by them. We were analyzing what we should do and the answer was that it would be
difficult for us, using a standard, objective risk model to justify turning those cable landing
facilities into military camps with [extremely high security], for an event that nobody with any
kind of statistical analysis could say was even remotely possible. Meteors can fall out of the sky,
but that doesn't mean we're all going to walk around with steel umbrellas. Is there information
sharing among the telecommunications providers in which you can share data on possible threats and
the risks they pose on a regular basis?
Our biggest threat against our infrastructure is by no means terrorism, it's natural catastrophes
to us. The recent earth quake in Chile and then the Pacific-wide tsunami threat that was issued by
the National Oceanic and Atmospheric Administration, those happen more often and if that tsunami
had turned out to be something to deal with, that represents a much more tangible threat to our
network given our cable facilities in the Pacific. We have all the contingencies in place to deal
with events like that, including a terrorist attack. As a matter of formal information sharing
between us and other ISPs, no we don't. There isn't a round-table or forum, either formal or
informal to share timely threat information.
Security of critical infrastructure:
SCADA
system, critical infrastructure security lacking, survey finds: T and security executives at
firms that own critical infrastructure facilities are concerned about the lack of security
protecting underlying management systems from attack.
White
House declassifies CNCI summary, lifts veil on security initiatives: Summary document outlines
ongoing initiatives to improve cybersecurity at the federal level as well as the security of the
supply chain and the private networks of critical infrastructure facilities.
Would a formal information sharing process be helpful or be inadequate for obvious
business and competitive reasons?
I would suspect that like myself, the other ISPs really don't have a lot to share, when it comes to
threats that are in that category to national security. We don't have an intelligence service like
the federal government. Occasionally we do hear about an underwater cable being severed, halting
communications to a country, explain how vulnerable certain countries are. Is it really that easy?
An underground cable can be severed causing major disruption?
If the end customer has critical infrastructure and it's not multi-tiered in which they get their
service from more than one ISP, if they can't route around the break, there could be an extended
outage. Specifcally a terrestrial cable break, under a manhole, can be fixed in hours. If it's an
undersea cable break, depending on the location of the break and the relative distance of the
dispatched ship that has to go out and pull the cable up and split it, then the outage is longer.
It happens several times a year. A real problem in the Pacific rim is undersea earthquakes break
the cable.
