Memorandum by Michael Forster (Network
Security Architect)
DEFINING THE
PROBLEM
What is the nature of the security threat to private
individuals? What new threats and trends are emerging and how
are they identified?
Individuals suffering financial fraud
(eg phishing, pharming, insecure internet connections, viruses,
spyware, insecure email correspondence, insecure web site usage).
Identity theft with consequential
loss (eg insecure public databases with more and more detailed
information all in one place).
Being framed for another's crimes
(eg through stolen credit card usage, or abuse of open wireless
networks attributable to individuals).
Some innocents being unfairly arrested
on inappropriate evidence (eg some of the victims of Operation
Ore).
Individuals unknowingly breaking
the law, or their family breaking the lawboth criminal
and civil (eg children on music download sites).
Loss of personal work (eg viruses
destroying creative work).
Loss of reputation (eg people displaying
their ignorance by suffering the above).
Loss of privacy (eg on hacked machines).
Distress caused to innocent parties
(eg children suffering from inappropriate emails, instant messenger
abuse, child exploitation).
IT specialists suffering attention
of organized crime and the threat of violence (eg bank security
staff held to ransom).
The loss of availability of IT functionality
(eg DOS attacks on DNS infrastructure).
What is the scale of the problem? How are security
breaches affecting the individual user detected and recorded?
The cases that reach the newspapers and courts
are likely to be a small percentage of all incidents.
How well do users understand the nature of the
threat?
Most users see a computer as "white goods",
in many ways a computer is more like a carwith similar
potential for catastrophe. The misrepresentation of threat levels
via press horror stories is also unhelpful, as they can conceal
the real facts and issues.
TACKLING THE
PROBLEM
What can and should be done to provide greater
computer security to private individuals? What, if any, are the
potential concerns and trade-offs?
New PCs being pre-installed with freeware security
software with no ongoing subscription requirements eg: Zonealarm
firewall (free for personal use) and AVG (free personal edition).
New IT equipment should be distributed with
a default of security on instead of off (eg wireless routers with
changed admin passwords).
What is the level of public awareness of the threat
to computer security and how effective are current initiatives
in changing attitudes and raising that awareness?
Generally poor, and somewhere between overconfident
and/or paranoidgiven the lack of detailed understanding
by consumers.
Maybe school initiatives on computer security
education issues could help.
What factors may prevent private individuals from
following appropriate security practices?
Ignorance of both the risks they are taking
and appropriate countermeasures.
The costs of subscribing to the security software
as supplied to them by the computer retailers.
The pervasiveness of the computer "White
Goods" mentality.
What role do software and hardware design play
in reducing the risk posed by security breaches? How much attention
is paid to security in the design of new computer-based products?
Generally, more so than ever before by the most
successful companies. Clearly Microsoft now see good security
as a business enabler rather than a pure cost. There are plenty
of companies about, however, that still need to learn this lesson.
Who should be responsible for ensuring effective
protection from current and emerging threats?
Clearly, some of the responsibilties lie with:
Individualspeople can't drive
a car without learning to drive and learning the law.
The IT industry"manufacturers
shouldn't sell cars which are lacking legally required safety
equipment and should strive to go beyond minimums." In similar
terms, ISPs publish "terms of use", which say things
like "you will not spread unsolicited email" (or viruses),
and "you will not scan other peoples systems for open ports",
but in practice they do not enforce their terms of use unless
someone (usually a victim), complains. If the ISPs actively policed
their terms and conditions, so that they warned customers as soon
as they had detected non-compliance with their policies,
then it would help avoid innocent customers who found their machines
being used by malicious 3rd parties, and also warn off any "wannabe"
hackers at the first opportunity. In practice ISPs focus on profit
and numbers of customers, instead of monitoring their consumer
compliance more ethically. ISPs could also do more to offer "secure
services" which filtered out aggressive incoming network
traffic.
Businesscompanies should provide
users with as safe an environment as possible to use their equipment
to do business with them, and accept some of the fraud risks.
GovernmentPolice should deter
and/or catch dangerous drivers, and the Government is responsible
for "highway code", driver licencing, and safety education.
What is the standing of UK research in this area?
The UK security industry is world leading, but
this has not been translated into a clear reduction in the risks
for UK computer users.
GOVERNANCE AND
REGULATION
How effective are initiatives on IT governance
in reducing security threats?
Some initiatives, eg the NISCC initiatives for
corporates, are very helpful. Similar information for the public
is less accessible.
How far do improvements in governance and regulation
depend on international co-operation?
Significantly, there is no point in local laws
in different countries being so mutually exclusive that some companies
can no longer legally do business with them.
Is the regulatory framework for Internet services
adequate?
ISPs should have more accountability for notifying
their users who are (possibly unknowingly) breaking the law.
What, if any, are the barriers to developing information
security systems and standards and how can they be overcome?
If there is no public perception of a requirement,
and no commercial pressure to provide, then there will not be
improvement. If the public want secure systems, and business sees
profit in secure systems, (which has started in some areas), improvement
can gather momentum.
CRIME PREVENTION
How effective is Government crime prevention policy
in this area? Are enforcement agencies adequately equipped to
tackle these threats?
While SOCA appears to have enough resource to
deal with high profile priority issues, it is questionable if
this is enough to support local police forces on less high-profile
cases. The lack of qualified forensic experts to support the courts
(and reveal innocence where appropriate) is also a potential source
of serious miscarriages of justice.
Is the legislative framework in UK criminal law
adequate to meet the challenge of cyber-crime?
Potentially it can be adequate, but only if
it can react quickly enough to the ongoing rapid changes in potential
threats.
How effectively does the UK participate in international
actions on cyber-crime?
Clearly more effectively than we have in the
past, Operation Ore found many guilty parties, but destroyed the
lives of too many innocents.
