    1 there is a word cybersecurity @alecmuffett www.greenlanesecurity.com

  • 8.

    2 this word is both a metaphor and a model for thinking about the challenges of information and network security @alecmuffett www.greenlanesecurity.com

  • 9.

    3 this model,with perhaps one exception, is unsuited to describe the challenges of information and network security @alecmuffett www.greenlanesecurity.com

  • 10.

    4 this model has been adopted by state actors as key to discussion and/or strategic consideration of information and network security @alecmuffett www.greenlanesecurity.com

  • 11.

    5 strategy based upon this model tends to be misconceived, expensive, and of an illiberal nature @alecmuffett www.greenlanesecurity.com

  • 12.

    6 unless diluted with other perspectives, this model is a lever for increased state control of information and network security that will harm the evolution of the field @alecmuffett www.greenlanesecurity.com

    http://www.cpni.gov.uk/threats/cyber-threats/ 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. @alecmuffett www.greenlanesecurity.com

    In 2009, Symanteccreated 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. @alecmuffett www.greenlanesecurity.com

    Malware Reaches RecordNumbers 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! @alecmuffett www.greenlanesecurity.com
