Cyber Security: 
”State of the (European) Union” 
• Threats are abundant and on the rise 
• http://map.ipviking.com/ is a good way to illustrate/visualize this 
• Existing tools, and even Next-Generation APT tools dont work:

• Tools are not the solution 
• No silver bullets exist

Want to beat assymetricality? 
Here’s how: 
• A strategic approach to security leveraging 
methods that work
Pyramids 
- This one is Joshua Cormans. 
Could be best definition of Defense-in-Depth 
Counter-measures 
Situational 
Awareness 
Operational Excellence 
Defensible Infrastructure
The Foundation 
Defensible Infrastructure 
Software and Hardware built as 
”secure by default” is ideal 
here. Rugged DevOps. 
Your choices of tech impacts 
you ever after 
You must assemble carefully, 
like Lego 
Without backdoors or Golden Keys!
Mastery 
Master all aspects of your Development, 
Operations and Outsourcing. Train like the 
Ninjas! 
DevOps (Rugged DevOps) 
Change Management 
Patch Management 
Asset Management 
Information classification & localization 
Basically, all the cornerstones of ITIL 
You name it. Master it. 
Operational Excellence
Gain the ability to handle situations correctly – Floodlights ON 
Are we affected by Poodle? Shellshock? 
WinShock? Heartbleed? Should we patch now? 
Next week? Are we under attack? Do we have 
compromised endpoint? Are there anomalies 
in our LAN traffic? 
”People don’t write software anymore, they assemble it” Quote Joshua Corman. 
-> Know which lego blocks you have in your infrastructure 
-> Actionable threat intelligence 
-> Automate as much as you can, example: IOC’s automatically fed from sources 
into SIEM with alerting on matches 
Situational 
Awareness
Counter that which you profit from 
countering 
• Decrease attacker ROI below critical threshold 
by applying countermeasures 
• Most Security tools fall within this category 
• Limit spending until you’re laid the 
foundational levels of the pyramid 
Counter-measures

Defensive hot zones 
• Basketball and 
other sports 
analysis -> 
• – FIND the 
HOT zones of 
your 
opponents. 
• Defend there.
Hot zones! 
• You need to secure: 
– The (Mobile) user/ 
endpoints 
– The networks 
– Data in transit 
– The Cloud 
– Internal systems 
Sample protections added only, not the 
complete picture of course
Best Practices – High level 
• Create awareness – Security awareness training 
• Increase the security budget 
– Justify investments BEFORE the breach. 
– It’s easier when you’re actually being attacked. But 
too late. 
• Use the Cyber Kill Chain model or Nigel Wilsons 
”Defensible Security Posture” to gain capability to 
thwart attackers 
• Training, skills and people!
Hot zone 1: Endpoints 
A safe dreamworld PC 
• Microsoft EMET 5.1 
• No Java 
• No Adobe Flash Player/Reader 
• No AV (that one is for you @matalaz) 
• Kill all executable files on the Proxy layer (.exe .msi 
etc.) 
• (Not even needed but works if something evades the 
above): 
– Adblocking extension in browser 
– Invincea FreeSpace/Bromium 
Vsentry/Malwarebytes/Crowdstrike Falcon
Hot zone 1: 
A real world PC 
• Microsoft EMET 5.1 
• Java 
• Adobe Flash Player/Reader 
• AV 
• Executable files kill you, so use: 
– Adblocking extension in browser 
– Invincea FreeSpace/Bromium 
Vsentry/Malwarebytes/Crowdstrike Falcon 
– Secure Web Gateway 
– White listing, black listing 
And then cross your fingers
Hot zone 1, more 
• PC defense should include: 
– Whitelisting 
– Blacklisting 
– Sandboxing 
– Registry defenses 
– Change roll-backs 
– HIPS 
– Domain policies 
– Log collection and review 
– MFA 
– ACL’s/Firewall rules 
– Heuristics detection/prevention 
– DNS audit and protection
Hot zone 2: 
The networks 
• Baselining everything 
• Spot anomalies 
• Monitor, observe, record 
• Advanced network level tools such as 
Netwitness, FireEye, CounterAct 
• Test your network resilience/security with fx 
Ixia BreakingPoint 
• Don’t forget the insider threat
Hot zone 3+4: 
Data in Transit/Cloud 
• Trust in encryption 
• Great new mobile collaboration tools exist 
• SaaS monitoring and DLP tools exist -> 
”CloudWalls” 
• Cloudcrypters 
• And this for home study: 
https://securosis.com/blog/security-best-practices- 
for-amazon-web-services
Hot Zone 5
Best practices 
• Use EMET 
• Use advanced endpoint mitigation tools like 
Bromium Vsentry, Invincea FreeSpace, 
Malwarebytes, Crowdstrike Falcon 
• Identify potential attackers and profile them
A safe(r) perimeter defense 
• Avoid expense in depth 
• Research and find the best counter measures 
• Open Source tools can be awesome for 
example Suricata 
• Full packet capture and Deep packet 
inspection/Proxies for visibility 
• Watch and learn from attack patterns
Best practices - Mitigate risks 
Source: Dave Sweigert
Automate Threat Intelligence IOC 
• Use multiple IOC feeds 
• Automate daily: 
– IOC feed retrival, 
– Insertion into SIEM, 
– Correlation against all-time logfiles, 
– Alerting on matches 
• Example: Splunk Splice can do parts of this
Future threat trends 
• 5G: The rise of the Android DDoS’er. 1 gbit/s 
connections from phones easily hacked. Obvious 
threat? 
• IPv6 – network reconnainsance surprisingly easily 
done: https://tools.ietf.org/html/draft-ietf-opsec-ipv6- 
host-scanning-04. Damn, no security 
through obscurity to get there 
• Countering Nation State Actors becomes a MUST
And the unexpected extra win 
• Real security will actually make you compliant 
in many areas of compliance
Q & A 
• Ask me question, or I’ll ask you questions

Editor's Notes

  • #2 Or join these
  • #17 The Egyptians built their pyramids from the bottom up. Because, that’s how you build pyramids. Start there!
  • #18 Laying a secure foundation matters supremely. History proves this
  • #19 As with any art, practice makes master. So, Practice!
  • #20 Automation is key for threat intelligence, threat detection and threat remediation
  • #22 Dont start by blindly buying tools, do the basics, master it and work from there
  • #29 In reality, you will have AV, Java and others. And you probably cannot enforce killing all executables
  • #30 In reality, you will have AV, Java and others. And you probably cannot enforce killing all executables
