Building a Security Strategy Without a Security Staff

Where do I start? Am I at risk of being targeted? How much should it cost? What is the ROI? What happens if I do it wrong? What do I do?!?!

These are some of the questions that every small or medium (SMB) sized business owner is asking in the wake of some of the most prolific and highly publicized data security breaches in history. Most people have forgotten about the massive TJX credit card breach of 2007 but recent breaches, such as those experienced by Sony Pictures Entertainment, OPM, and Anthem, have found their way into typical conversations at coffee shops, family events, and holiday parties of the average consumer. The difference, however, is that most SMBs have neither the money, expertise, nor the forgiving customer base which would allow their business to survive a similar breach.

So how does a SMB, that is increasingly responsible for the security and privacy of customer and employee information, mitigate a serious and perhaps business-ending data breach? This session will present real world strategies to prepare for, mitigate, and respond to incidents posed by opportunistic attackers, malicious insiders, and targeted attackers - taking into account real-world constraints such as time, expertise, business continuity, and money.

  10. 14 When You Get To Start Fresh • This is

    the ideal (and highly unlikely) situation • You – Likely have budget – Get to architect security – Can position purchases as cost of doing business – Can enforce policy and program goals from day one

  12. 17 When You Inherit The Wanderer • Inheriting The Wanderer

    is a more likely occurrence than a net-new security program – Especially in SMB/SME • You need to be prepared to be told: “You are/were the security spend…” “We’ve never been breached before…” “We have nothing the attackers want…” • It’s often an uphill battle

  14. 19 Security In The Not-So-Fortunate 500 • When I say

    Not-So-Fortunate 500 I’m referring to companies that have less than (or equal to): – 500 employees – 0.5% of IT budget allocated for security – 0.25 to 1 full-time employee (if they’re lucky)

  26. 32 ”Cost and Effect” • As you can see, the

    recommendations we present to SMB are – Expensive – Based on enterprise security industry experience – Untenable for most • How do we address this by… – Looking the other way – Imposing Government – Penalizing into submission
  27. 33 Why Do We Punish SMB? • Breach laws are

    enacted to promote better safety and security of customer data – And, by proxy, small businesses • This is a combination of carrot, stick, and bullying • Why don’t we try incentivizing?
  28. 34 Why Do We Punish SMB? • Look to The

    Speed Camera Lottery - The Fun Theory https://www.youtube.com/watch?v=iynzHWwJXaA
  29. 35 The Speed Camera Lottery • The Speed Camera Lottery

    – The winning idea of the fun theory award, submitted by Kevin Richardson, USA – Can we get more people to obey the speed limit by making it fun to do? – Volkswagen, together with The Swedish National Society for Road Safety, made this idea a reality in Stockholm, Sweden • Speed citations go into a pot – Drive legally, get entered into a lottery for the a share of the pot – Speeding decreased 22% during experiment
  30. 36 Incentivizing Ideas • What if we rewarded better business

    practices instead of only punishing bad ones? – Card merchants could provide preferred rates for transactions… – Government could provide bursaries or “credits” for responsible security operations • Think “Carbon/Emission Credits” – Insurance premiums could be reduced

  38. 44 Summary • We need to incentivize organizations to operate

    more securely • We’re asking a lot of SMB and SME market segments – Can’t get blood from a stone • To properly secure our SMBs, we need to take small, iterative bites from problem – There is no magic/silver security bullet
