Memorandum by the National Computing Centre
Limited
SUMMARY
1. In this response to the House of Lords
Science and Technology Committee inquiry into Personal Internet
Security, the National Computing Centre recognises that the personal
user community is starting to protect itself in certain respects
(such as an increased use of antivirus and firewall software)
but is exposing itself more through the proliferation of opportunities
for self-publicisation (vanity publishing) that the Internet encourages.
The energy needed to get to grips with the real and apparent complexities
of the measures for secure use of computers is locked in battle
with the pervasive complacency that research suggests to be the
second to largest, most prevalent risk.
INTRODUCTION
2. The National Computing Centre (NCC) is
pleased to have the opportunity to deliver the evidence herein
on security issues affecting private individuals when using communicating
computer-based devices, either connecting directly to the Internet,
or employing other forms of inter-connectivity.
3. NCC is the single largest and most diverse
corporate membership body in the UK IT sector.
4. NCC champions the effective deployment
of IT to maximise the competitiveness of its members' business,
and serves the corporate, vendor and government communities.
5. NCC delivers a continuum of services
including; independent and impartial advice and support, best
practice and standards, personal and professional development,
managed service delivery, awareness raising and experience sharing.
6. These services are designed to support
IT and IS professionals and their teams throughout their management
careers and faciliate operational excellence in the industry.
NCC is a social enterprise owned by and run for the benefit of
its members.
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?
7. The security threat manifests itself
to individuals in three aspects of privacy risks.
The first is the most publicised
under the label of identity theft where personal details are harvested
with nefarious intent to imitate the victim to defraud them directly,
or use the alias to defraud others.
There is also a growing trend for
vanity publishing of personal details. This may be harmless fun
for some but may encourage the attention of "cyberstalkers"
or paedophiles to others.
Thirdly there is the ease of which
information about individuals activities may be posted to the
Internet thus making public what may be previously have been expected
to remain private.
What is the scale of the problem? How are security
breaches affecting the individual user detected and recorded?
8. Research focuses on the institutional
experience and so recording is done by, for example, banks who
have to deal with the effects of a breach (such as illegally "authorised"
transfers of funds). The fear of reputational risk probably adds
another level of constraint on the free reporting that would gauge
the scale of the problem. It would be difficult to have a meaningful
reporting point for individuals who have suffered a security breach
as they are likely to expect that the responsibilities for their
protection lie with the institution from who they seek recompense.
Home users who have certain security countermeasures from some
vendors can report breaches which are used to update records.
However the key problem to this is the availability of this information
and the need to have a particular configuration. There is a wider
theatre of victims who will suffer the inconvenience of a security
breachsuch as a virus infiltration or loss of control during
a Distributed Denial of Service attack, and having expended energy
in overcoming the problem will not look for any authoritative
reporting point.
Note: The last sentence of this paragraph
is an example of the communications problem endemic to the whole
issue on improving personal security. The majority of the population
want computers to access services and are being forced into having
to increase their technical appreciation of how they work so that
they will understand the need, and therefore means, to defend
them.
How well do users understand the nature of the
threat?
9. Users do not, on the whole, understand
these threats well. They have to:
be aware of the threat itselfsuch
as identity theft (we note the coincidence of this consultation
with a national campaign to protect against this);
understand that the mechanism through
which this threat is realised can be:
(i) technicalsuch as the covert installation
of software to harvest identification details;
(ii) socialsuch as e-mails which either
play on the psychology of Internet activity like the entering
of usernames and passwords into familiar looking websites; and
(iii) sociotechnicalsuch as e-mails
which goad the user into an action that leads to (i).
then understand the solution to the
problem which will vary from resisting temptation to open an unexpected
e-mail attachment to having to update the software on a computer
to prevent many forms of malicious software embedding itself;
and
fight complacency. An NCC survey
into the top IS/IT risks identified "Complacency, lack of
awareness or understanding of risks, or accepting too much risk"
as the second most prevalent potential problem. This reflects
the human limitation of misapplying personal experience and discounting
past and future risks.[17]
10. Evidence that users would appear not
to really understand the problem is shown by the growth in the
use of websites which encourage the divulging of personal information
(eg myspace). Even if they are not explicitly stating exploitable
details, they are passing on the first leads to identity thieves.
One might even say that "bloggers are asking for it"
by advertising lifestyle and personal details. It has been suggested
that the humble "out of office reply" is an invitation
to would be thieves to track down unattended property.
11. Examples of this vanity publishing can
be seen at:
http://www.faceparty.com/
http://www.youtube.com/
http://en.wikipedia.org/wiki/List_of_social_networking_websites
12. These sites are also an obvious port
of call for even more perfidious practices as creating false personas
with criminal intent other than identity theft.
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?
13. There is no silver bullet. An "in
depth" approach is needed including:
Authoritative parenting that preventsor
at the very least discouragesthe development of inappropriate
web-posting behaviour.
Continuous improvement of software
quality by the developers and service providers to reduce vulnerabilities
in the hardware and software.
More researchand realisation
of its resultsto enable the distribution of improved software,
operating systems and applications, including protective software,
to a non-technical audience.
In-built security tools at levels
across the technical spectrum (from network to applications and
data) to protect the novice but flexible enough to be switched
off by the more expert user who wants to increase their level
of protection.
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?
14. Initiatives are increasing and improving
in quality, notably http://www.thinkuknow.co.uk/ and http://www.getsafeonline.org/.
However we should ask whether the Internet is the right place
to treat the perception and understanding of problems with the
Internet? An "in depth" approach using non-Internet-based
resources is necessary.
15. The number of helpful sites can be as
overwhelming as the incoming phishing e-mail. For example there
are:
http://www.cardwatch.org.uk/
http://www.codephish.info
http://www.identitytheft.org.uk/
16. Whist some specialist information can
be found:
http://www.howtowipeyourdrive.com
http://www.microsoft.com/security/protect
http://www.millersmiles.co.uk/
http://www.spamfo.co.uk/
What factors may prevent private individuals from
following appropriate security practices?
17. A lack of understanding of the technology
leads to a natural lack of understanding of how threats can be
realised through that technology. We may expect to see that those
attacks which are difficult to detect becoming more costly to
deal with as they are likely to have embedded problems into say,
several generations of back-up, before being discovered. Personal
backing up of data is unlikely to be well practised. Pride in
good practice should be encouraged but it must not lead to complacency.
Security breaches are like mermaids: just because you haven't
seen one doesn't mean that they don't exist. We need to encourage
development of trust technologies so that we can let in a few
constant friends rather than trying to bar a changing crowd of
foes. But don't forget the security in depth principle of not
relying on any single approach.
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?
18. The lesson has been learnt by the software
vendors but they are to an extent hostage to fortune that the
proliferation of hardware and software means that there is rarely
anything new under the sun. New innovation has still to interoperate
effectively with legacy technology and the nature of software
means that it is almost impossible to guarantee the permutations
encoded in a product will secure that product in most (or more)
configurations.
19. This is why the in-depth approach combining
accountability, technology and education is essential:
AccountabilityCreate a system
of recognition for legitimate Internet "crawling" software
so that Internet Service Providers (ISPs) can block unrecognised
(perhaps uncertificated) attempts to harvest information. Legitimate
applications (for example, Google, AltaVista, and Autonomy) would
bear electronic authenticity certificates.
TechnologyTechnology should
be developed with mandatory attention to the non-functional requirement
of security.
EducationThe responsible use
of information technology should be part of the compulsory curriculum
of citizenship in schools.
Who should be responsible for ensuring effective
protection from current and emerging threats?
20. Now that the Department of Trade and
Industry's biannual survey of security breaches in business is
making the happy report that the high proportion of businesses
are catching the security incidents, it is the time to strengthen
the user community with the sharing of the effective measures.
It would seem that there is a watershed of attack running from
the protected (corporate) to the unprotected (small businesses)
and we see this continuing beyond, to the personal users of information
technology.
21. Information is passed along a convoluted
network of veins, arteries and capilaries, its security is at
risk throughout the journey. It is more vulnerable in some places
than others. Like the straight Roman roads, we must reduce the
kinks and bends where the enemy can lurk.
22. It is undoubtedly good news that more
attacks are being detected. We may expect less damage from those
which are easy to detect providing defences are strong throughout
and we do not get caught by a weakness that is exploited whilst
in the shadow of a well defended system.
23. We may never have everyone fighting
the information security war. We can recognise that although some
may sit and watch, others dive into the thick of it, and some
run after with a stretcher, we must always strive for inclusiveness.
Where information is managed using technology, understanding all
the implications will get technical. Initiatives like "Get
Safe On Line" have vital roles but to paraphrase Einstein,
it can make the solution as simple as possible but no simpler.
Vulnerabilities and patches are "techie". Just as we
have seen the Botnets run from the watershed of protection into
the trenches of home or small business computing, we need to stem
the flow by doing as much as we can to make security measures
accessible or automatic. This can be shored up with the increasing
desire for professional recognition in information security with
a professional institute at its zenith.
What is the standing of UK research in this area?
24. We should be making it easier to achieve
commensurate levels of assurance (realising relative security)
by paying attentions to lessons learnt from experience. The certification
of Japanese organisations to the Information Security Standard
BS 7799/ISO 2700 far exceeds that of UK certification. We should
consider an investigation of how Japanese individuals may be benefiting
by the formalisation of information security management by those
who service them.
25. Recent reports have highlighted that
(a) Internet misuse has switched from more nuisance to criminal
intent and (b) rather than attack defended corporate networks,
these criminals are taking advantage of more vulnerable information
technology of home and small business.
26. Research is needed into how we may promulgate
the lessons learnt by the corporate experience to those who want
the benefit of technology without the having to master much if
any of its complexity.
GOVERNANCE AND
REGULATION
How effective are initiatives on IT governance
in reducing security threats?
27. It is good that there are initiatives
which recognise the "chain" of responsibilities that
connects the corporate, public sector, small business and personal
information technology users. Only in that wider context can the
actions on the individual be put into context.
28. The formalisation of ethics and good
governance in the UK, leading to a demand for demonstrable management
of operational risk, has largely matured since the last decade
of the Twentieth Century. As seems to be usual, the emergent risk
of tardily reported inadequacies in high-level governance with
the Maxwell pension funds, the Bank of Credit and Commerce International
(BCCI), and Polly Peck became the driver. The first set of improvements
was proposed by Sir Adrian Cadbury, former chairman of the Cadbury
chocolate company, in "The Financial Aspects of Corporate
Governance". This was a code of conduct for stock market-listed
companies addressing ethical as well as legal questions. The implementation
only really became clear when Turnbull prompted attention to risk
management.
29. This evolution of benchmarks for corporate
governance was given focus by a working party of the Institute
of Chartered Accountants in England and Wales (ICAEW). This was
led by Nigel Turnbull, so the subsequent documents "Internal
Control: Guidance for Directors on the Combined Code" has
become known as the "Turnbull Report". Its message is
that good corporate governance is achieved by internal controls
and risk management. Like Sarbanes-Oxley and Basel II, financial
prudence is the driver and a high quality of transparent reporting
is a key aspect of compliance. Risks need to be managed and their
acceptance must be from the highest level.
30. The ability to put this into practice
has been greatly boosted by the Higgs Report which reviewed the
roles and effectiveness of non-executive directors in the UK.
As a result, the report sets out measures designed to improve
the structure and accountability of boardrooms in the UK. This
is vital to instil a transparent approach to risk management.
31. Government is concerned with enabling
the public and private sectors as well as individuals to achieve
secure and resilient information systems. To achieve this, the
UK has established the Central Sponsor for Information Assurance
(CSIA) to facilitate working in partnership with the public and
private sector to address the protection of information systems,
the information they carry, and their users from hi-tech crime.
The department promotes education and awareness of information
security and takes in hand training and skills for professionals.
32. The confidentiality, availability and
reliability of information systems and the information they handle
is an important concern for Government. The continuous provision
of goods and services to citizens depends on the smooth running
of the information systems supporting themparticularly
in the event of a crisis. But Government cannot make the UK's
information systems secure by itself. Most information networks
are neither owned nor operated by Government so we each must play
a part in protecting all our information systemsfrom home
computers, to the IT networks behind large companies to local
and central government systems. In fact we are becoming so interconnected
that the contagion from a home computer can spread to business
and into Government and vice versa. We need to develop a new culture
of cybervigilence which means that we must not only protect our
computers from viruses, we must protect our privacy and identity
from those who would abuse it. The complexity of the risks requires
a scalable approach that can be made to fit the size and place
of impact. A risk mitigation framework standards can be designed
as to account for the risk and stakeholder view or weltanschauung
in its application. Risks to security are no longer a simple matter
of who you keep out; they are a complex and changing set of layers
that decide who you let it in and how far. NCC is engaged in the
research and development of such a framework.
How far do improvements in governance and regulation
depend on international co-operation?
33. International co-operation is important
to combat the perception of the relative safety of perpetrators
who take advantage of technical and social vulnerabilities from
regimes that they feel safe in.
Is the regulatory framework for Internet services
adequate?
34. No commentary submitted.
What, if any, are the barriers to developing information
security systems and standards and how can they be overcome?
35. Information and knowledge are the thermonuclear
competitive weapons of our time.[18]
Any information that an organisation holds is an important asset
and needs to be treated as such. Risks are inherent in the software
driving information systems that store and process that information.
It is therefore not surprising that in order to secure information,
international consortia (such as the Basel Committee for Banking
Supervision) and governments have set out regulations with punitive
measures for non-compliance to encourage a proactive response
to risk. Individual examples of compliance are knitted together
under the banner of good governance so that risks to the disclosure
of sensitive, personal information carry national and international
obligations rather than allowing the risk of disclosure to be
accepted. In addition to the social obligations of the regulatory
regimes, information system users are typically at risk from e-crime
including the misuse of computer systems for fraud, hacking, virus
and denial of service attacks, software piracy, on-line child
abuse, extortion and drugs trafficking. In addition to the social
protection and e-crime, misuse (deliberate or accidental) of information
systems by otherwise legitimate users is still the highest security
risk.
36. Regulatory bodies react to emergent
risk by creating laws and regulations (social obligations) to
promote the environment in which organisations have to manage
risk as part of their operations. The drivers for organisations
to proactively respond to these emergent, undesirable outcomes
are regulatory pressures. According to some recent commentary
from the USA this is now less so and the argument to invest in
security because of, for example the Sarbanes-Oxley Act, is no
longer resonating at board level. Because, although risk management
is a continuous process, regulations are seen to be "here
and now". In contrast, there is faith that (non regulatory)
risks can be avoided. This section discusses how national and
international, government, and non-governmental organisations
have recognised the need to either establish policies for managing
risk or deliver tools to implement policies.
37. National Computing Centre members were
consulted on their attitude to standards to investigate whether
the hearsay and anecdotes that suggested dissatisfaction in the
accessibility of information in standards could be found in a
cross section of stakeholders in information systems. The following
discussion is collated from feedback collected during this consultation
and not previously published. It drew out the opinion that the
presentation of standardsand the processes used to develop
themare flawed. It is especially relevant to this paper
because it shows how the proposed risk treatment framework can
itself mitigate some of these concerns.
38. Standards appear to be unpopular amongst
information system stakeholders because of their perceived complexity,
the many sources offering apparently helpful standards, difficulties
in the visible process of defining standards, the rigidity of
compliance requirements, and the cost of the documentation. Each
of these concerns is described in more detail below, before discussing
how the work to be done in response to the observations made in
this paper may help to overcome the apparent consternation towards
standards.
39. The complexity of standards is thought
to result from the need to try to include not only the intended
scope of implementing a technology or process, but also predict
the effect of unintentional applications. This results in the
perception of much of the information in standards as being preventive
and therefore negative. Successful standards are seen to be simple
or minimalist, with the emphasis on communication rather than
`prevention'. Although it is undoubtedly important that the impact
of proposed changes are understood, it is more important that
the need for the change is recognised and accepted by all stakeholders.
Leadership and teamwork were cited as the framework for successful
projects; standards provide a communications medium within that
framework.
40. The source of standardisation was also
noted to be an area of confusion with many contributors to the
body of knowledge of IT standardisation. One respondent to the
survey cited, as examples, ECMA, ITU, BSI, and ISO. Another respondent
referred to the declaration of certain suppliers as being the
owners of standards whereas they may have been more successful
in penetrating the market place with a particular technology.
References by separate respondents to the consultation were made
to the remark by Andrew S. Tanenbaum[19]:
"The nice thing about standards is that there are so many
of them to choose from", referring to the proliferation of
standards, and the bawdy "The Matelot's Prayer"[20],
intimating a love-hate relationship with standards whose proliferation
is not differentiated by quality.
41. The development process in which standards
are formulated, reviewed, agreed, and then published was deemed
to take too long, have too many roles involved, and be too concerned
with synthesising a product that satisfies all view points. The
problems were specifically reported as time consuming, bureaucratic
and the need to compromise to reach a consensus. The derivation
of standards from a series of meetings, will normally take place
over a period of years where as market changes and business opportunities
seem to be more immediate. The layers of committees and standards
bodies mean that it is very difficult to navigate how a standard
is progressing or have access to the latest thinking until a consensus
is reached. The effort to gain agreement is time consuming and
can lead to the omission of useful information that, having been
removed during editing, is not circulated to the wider standards
audience.
42. Whereas kite marking by the British
Standards Institution of certain products such as glass, hot water
bottles, and tyres commands a certain degree of respect in the
relevant market places, compliance with information system standardsparticularly
process standardsdoes not command similar respect where
standards are expected to deliver a degree of assurance on the
part of the supplier. Compliance is also seen as difficult as
there seems to be limited understanding that there is more than
just simple pass-fail tests to be applied, particularly in a complex
IT system.
43. The cover price of standards is regularly
seen as prohibitive, particularly to small businesses who see
the full cost in terms of `cash flow' rather than the benefits
that accrue from the implementation of the standard, possibly
on many occasions, spreading the cost over more then one project.
44. A framework where standards are linked
as solutions to risk may mitigate many of these perceived flaws
by making accessible and more obvious, the information in standards
that is directly relevant to operational issues. This may be accomplished
by using a taxonomy-centric framework that avoids adding any layers
of complexity to the standards. A framework may be designed to
overcome complexity through navigation based on stakeholder views
and "deliver" a standard from one of several sources
to treat a risk regardless of bias to the publisher of that standard.
The corollary being that the uptake of standards could increase
risk awareness and reduce the failures that have given concern
over the performance of certificated organisations. Working within
the framework proposed in this paper will not make standards cheaper
but it could be used to direct users to very specific standards
that will offer them value for money through the treatment of
otherwise expensive risks. Changes to the bureaucratic standards
development process are outside the scope of the commentary in
this paper.
CRIME PREVENTION
How effective is Government crime prevention policy
in this area? Are enforcement agencies adequately equipped to
tackle these threats?
45. Crime prevention policy needs to be
embodied in a comprehensive campaign that spans education to encouraging
and supporting co-operation between public and private institutions.
It should be built on accountability, education and co-operation:
AccountabilityRetailers should
expect to only sell "locked down" products which meet
the current standard of security "out of the box". Users
would be able to accept risk by switching off facilities if they
have an appropriate level of understanding to manage those risks.
Products could be certificated (for example as an extension of
the CSIA Claims Tested (CCT) Mark and retailers could be accredited
for their adherence to this approach to security.
EducationResponsible and acceptable
use of information technology needs to be embedded in the education
of children and adults. This must range from an understanding
of what's safe to do on-line and where different facilities mean
different approaches to what they are used for. Transactions from
a mobile phone are not the same as transactions from a personal
computer at home and are not the same as transactions from a computer
in a café or library.
Co-operationNotification of
vulnerabilities and breaches needs to be shared so that timely
action can be taken.
Is the legislative framework in UK criminal law
adequate to meet the challenge of cyber-crime?
46. The UK and the International community
needs a framework that encourages disclosure of breaches to ensure
that (a) the scale of the problem is clear and (b) the risks that
are realised are notified in sufficient time for other potential
victims to take preventive action.
How effectively does the UK participate in international
actions on cyber-crime?
47. No commentary submitted.
