  2. Whoami? Design secure infrastructure MVP – Enterprise Security Speaking engagements Security Team Manager Truesec Incident responce Security Assessments/Penetration Testing

  3. Session Goal • Make you start thinking about testing your security • Give some EXAMPLES of things you can test • Provide some tools/methods/ideas on testing

  4. Why do wee need to care about threats?

  5. Sony PSN

  6. 8 Deadly sins in IT-Security • Unpatched systems • Weak passwords • Weak exposed client applications (Hardening/configuration) • Weak exposed server services (Hardening/configuration) • Weak local applications (Hardening/configuration) • Sensitive network traffic exposure • Weak access control to protect sensitive data • System dependencies

  7. Unpatched systems • 2 different approaches to choose from • Patch inventory platforms • MBSA • Shavlic • Etc.. • Vulnerability scanners/attack testing platforms • Core Impact • Nessus • Metasploit • Etc...

  8. Unpatched systems

  9. Weak passwords • Many places to test • Active Directory • User accounts • Computer accounts! • Local SAM • Other services (SQL/Webapplications/VNC etc., etc.) • 2 main methods • Active testing (Brute force/dictionary) • WARNING – don’t forget password lockout policys! • Passive testing

  10. Weak passwords

  11. Weak exposed client applications (Hardening/configuration) • Common issues: • Macro Security! • Outdated versions of applications • Browser plugins • Acrobat reader (over and over again...) • Java • Tools: • https://browsercheck.qualys.com/

  12. Weak exposed client applications (Hardening/configuration)

  13. Weak exposed server services (Hardening/configuration) • Most common: • WEB • SQL • Testing: • Web/sql is challenging to test • There are automated tools out there • Often misses weaknesses • False positives common • Manual testing by experienced tester is recommended • Common weaknesses: Injections/XSS/shared passwords embedded in client application etc. etc.

  14. Weak exposed server services (Hardening/configuration)

  15. Weak local applications (Hardening/configuration) • Anything that is run in admin privs and writable with user privs • Registry • File system • Services • Scheduled Tasks • Processes

  16. Weak local applications (Hardening/configuration)

  17. Sensitive network traffic exposure • Weak protocols: • SMB • http • telnet • Snmp • ftp • RDP • Etc.. • Tools: • Wireshark/Cain etc.

  18. Sensitive network traffic exposure

  19. Weak access control to protect sensitive data • Very often high privileges are stored in files accessible by domain users or even everyone! • Scripts • Backups • Webconfigs • Password reaminder docs • Config files

  20. Weak access control to protect sensitive data

  21. System dependencies • Very often the privileged accounts are stored on systems with lowers security demands • Local admin reuse • Exposed Domain admin logons • Reused service accounts • Tools: • Gsecdump • Lslsass • parallelltask

  22. System dependencies

  23. Process of testing • Decide what tests you want to run • For each test: • Set up a test goal • Identify targets • Find the right tools • Identify risks • Define and try methology to manage risks • Backup/restore/Rollback/Failover/Point of contact • Set up a test methology • Test in a controlled environment • Get acceptance from system owners!! • Perfom test • Analyse result • Take actions

  24. Some resources  • Open Source Security Testing Methodology Manual http://www.isecom.org/osstmm/ • Microsoft Baseline Security Analyzer 2.2 http://technet.microsoft.com/en-us/security/cc184923 • Nessus http://www.nessus.org/products/nessus • Truesec.com www.truesec.com
