Newsscan Computer Security Column
Stephen and Chey Cobb, CISSP
Who You Gonna Call For Help?
Welcome to the first of what we hope will be many columns
on computer security, written for Newsscan by the husband and wife team
of Stephen and Chey Cobb. Seasoned computer industry veterans, Stephen
and Chey are both Certified Information System Security Professionals
and published experts. They plan to use this column address both the basics
of computer security and the background to recent security news.
Whom Are You Going To Call?
A formal rendition of the haunting refrain from the theme to “Ghostbusters”
nicely summarizes one of the most pressing security dilemmas facing today’s
highly-connected enterprises: When your organization experiences a security
incident, do you tell anyone about it? And if so, whom?
Earlier this year a survey of 8,100 technology and security
professionals by InformationWeek revealed that 40 percent of businesses
that experienced a serious security breach told nobody. Only about a quarter
of that 40 percent informed a government authority or CERT/CC, the Computer
Emergency Response Team/Coordination Center at Carnegie Mellon University
(www.cert.org). It was also disclosed this week that some businesses have
even been paying blackmail to hackers in order to keep the news of hacks
against their organizations secret.
More worrying still, for businesses in general, is that
85 percent of businesses that suffered a security breach neglected to
inform their business partners of the problem. Without being cynical,
one can speculate that many of the partners would have found out anyway,
given the highly interconnected nature of today’s business relationships.
Regardless of speculation, the implication is pretty clear: if a security
incident occurs at a company with whom you do business, they probably
won’t inform you, if they can avoid doing so.
Why worry about this? Because however well you protect
your own systems, they are bound to connect, at some point, with other
systems, the security of which is not under your control. If you have
been diligent, you will have obtained assurances from the entities with
whom your systems connect as to their security polices and procedures.
But how do you know they are living up to those assurances? Some companies
are now including, or rather, attempting to include, security audit rights
in business contracts. Of course, most companies will, if their bargaining
position allows, object to such clauses.
Whether or not you are able to obtain the right to audit
a business partner’s security assurances will depend on a variety
of factors, but in any event you should definitely push for the next best
thing: an assurance that you will be informed if there is a security incident.
So why is telling others about a security incident so important?
After all, there would appear to be numerous downsides to revealing that
your defenses have been breached: embarrassment, loss of partner and customer
confidence, and liability. Below are our five reasons why you should at
least let law enforcement and CERT/CC know about your security problems:
1. They may know more than you do. Even if your organization
has devoted a lot of resources to security, you are unlikely to have the
full picture in terms of current attack activity levels, techniques, and
targets. For example, if an individual is attempted to extort money from
your organization over a security issue, you may not be alone. Local or
national law enforcement may be aware of this scheme and may already be
investigating.
2. They can help you. Compared to just a few years ago,
you will find a lot more sophistication with respect to computer security
incident handling in your local FBI office and local law enforcement agencies.
They can usually direct you to additional resources for assistance.
3. You can help them. The folks who are fighting to defend
computer systems are in dire need of more data about the problems they
are trying to solve. The small bit of data you give them may just be the
bit that they need to be able to determine a new trend or to put them
on the track of the perpetrators.
4. They’ll find out anyway. Many questions about
liability arising from security breaches remain unanswered, but one thing
seems fairly certain, keeping the lid on incidents is increasingly difficult
to do. A clear lesson from history is that you can get into more trouble
from trying to cover something up than from the thing itself.
5. There may be more gain than shame. Organizations that
are upfront about their security problems may well garner both respect
and sympathy. This is especially true if you have been doing a good job
securing your systems but fall victim to a new and unusual attack.
And, remember … Information is everyone's best defense.
The more we share that information, the stronger we all become.
