@alecmuffett www.greenlanesecurity.com

1there is a word cybersecurity

Page 9: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

2this word is both a metaphor

and a model for thinking about the challenges of information

and network security

Page 10: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

3this model, with perhaps one exception, is unsuited to describe the challenges of

information and network security

Page 11: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

4this model has been adopted bystate actors as key to discussion and/or strategic consideration

of information and network security

Page 12: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

5strategy based upon this model

tends to be misconceived, expensive,and of an illiberal nature

Page 13: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

6unless diluted with other perspectives,

this model provides a lever for greater state control over

information and network security that will harm the evolution of the field

2what model does it represent?

Page 59: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

not cyber-space

Page 60: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

but cyber-space

Page 61: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

a near-tangible virtual world

Page 62: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

described as a space

Page 63: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

people meet in a space

Page 64: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

battles are fought in a space

Page 65: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

wars are waged in a space

Page 66: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

humans understand space

Page 67: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

underlying assumption is that cyberspace is sufficiently like realspace

and much the same rules can apply

Page 68: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

but, alas...

Page 69: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

3the model is a mostly-bad fit to reality?

Page 70: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

cyberspace is not like realspace

Page 71: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

example 1: theft

Page 72: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

cyberspace theft is not commutative

Page 73: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

theft in realspace•if I steal your phone

• you no longer have it• it is gone

Page 74: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

theft in cyberspace•if I steal your data

• you still have it• unless I also destroy your copies

• assuming you haven’t backed-up your data

• you no longer have secrecy• not the same as “loss”

Page 75: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

later debate:is intellectual property theftactually theft (ie: crime) ...

Page 76: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

... or is it like copyright infringementand/or patent infringement

(ie: typically a tort)?

Why regulate newspapers & journalists on Twitter,

yet not regulate Stephen Fry?

Page 86: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

On Twittereveryone is the same size

0 = no twitter account1 = twitter account

Page 87: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

On Twittereveryone has equal capability

tweet, or not-tweet, that is the question

Page 88: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

On Twittersome have much greater reachwhich is not the same thing as size

a node/vertex/twitterer is a pointand is of zero dimension;

hence all twitterers are the same size

@alecmuffett www.greenlanesecurity.com

a line/edge/follow is thatwhich joins two nodes/twitterers

Page 94: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

the degree of a twittereris the number of followers,

the number of people with whomyou communicate

Page 95: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

the only metrics on twitter•volume

• number of tweets

•indegree• number of followers

•outdegree• number of people you follow

Page 96: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

so which of these three metricsshould trigger state regulation

of your twitterfeed - regulation of what you may say?

Page 97: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

if none, perhaps regulation shouldpertain to the author & his message

rather than the medium

Page 98: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

if the medium is irrelevant and open,why discuss regulation of the medium

rather than of its users?

ts/ Cyberspace lies at the heart of modern society; it impacts our personal

lives, our businesses and our essential services. Cyber security embraces both the public and the private sector and spans a broad range of issues related to national security, whether through terrorism, crime or industrial espionage.

E-crime, or cyber-crime, whether relating to theft, hacking or denial of service to vital systems, has become a fact of life. The risk of industrial cyber espionage, in which one company makes active attacks on another, through cyberspace, to acquire high value information is also very real. Cyber terrorism presents challenges for the future. We have to be prepared for terrorists seeking to take advantage of our increasing internet dependency to attack or disable key systems.

CPNI works with the Cabinet Office and lead Government departments and agencies to drive forward the UK's cyber security programme to counter these threats.

to define communication•propaganda

• a bad word in government lingo• also marketing & public relations

The cost of cybercrime to the global economy is estimated at $1 trillion

[US General Keith] Alexander stated and malware is being introduced at a rate of

55,000 pieces per day, or one per second.

The annual cost of cybercrime is about $388 billion, including money and time lost, said Brian Tillett, chief security

strategist at Symantec. That’s about $100 billion more than the global black market

trade in heroin, cocaine and marijuana combined, he said.

Symantec “Global Internet

Security Threat Report- Trends for 2009”

Page 162: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

In 2009, Symantec created 2,895,802 new malicious code signatures (figure 10). This is a 71 percent increase over

2008, when 1,691,323 new malicious code signatures were added. Although the percentage increase in signatures added is less than the 139 percent increase from 2007 to 2008, the overall number of malicious code signatures by the end of

2009 grew to 5,724,106. This means that of all the malicious code signatures created by Symantec, 51

percent of that total was created in 2009. This is slightly less than 2008, when approximately 60 percent of all

signatures at the time were created.

Page 163: Why Cybersecurity Is Rubbish

McAfee Threat Report:Fourth Quarter 2010

Page 168: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

Malware Reaches Record Numbers

Malicious code, in its seemingly infinite forms and ever expanding targets, is the largest threat that McAfee Labs combats daily. We have seen its functionality increase every

year. We have seen its sophistication increase every year. We have seen the platforms it targets evolve every year with increasingly clever ways of stealing data. In 2010

McAfee Labs identified more than 20 million new pieces of malware.

Stop. We’ll repeat that figure.

More than 20 million new pieces of malware appearing last year means that we identify nearly 55,000 malware threats every day. That figure is up from 2009. That

figure is up from 2008. That figure is way up from 2007. Of the almost 55 million pieces of malware McAfee Labs has identified and protected

against, 36 percent of it was written in 2010!

are we spending enough?”- Audience Member, BCS Meeting Cyber Challenges of 2012

* Actually closer to $11bn

Of the £640m

9% (£58m) goes to cybercrime

65% (£416m) goes to operational capabilities

bureaucracy, goals and targets

Page 214: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

ie: this specific idea would be doomed...

Page 215: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

...and any Government projectto lead security would be likewise?

Page 216: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

But if you could address security in a distributed manner...

Page 217: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

then why instead spendall that taxpayer money centrally?

Page 218: Why Cybersecurity Is Rubbish

@alecmuffett www.greenlanesecurity.com

Perhaps cybersecurity isn’t actuallyabout protecting the public?

Page 219: Why Cybersecurity Is Rubbish
