12. Game Approaches

13. Game Approaches and tools
● Visual Studio
● .NET
● mono
● dotnetcore
● perforce
IMPORTANT: CPU cores usage and HT

14. Crytek Approach

15. Crytek Approach
● dotnetcore - official
● Minimize attack surface from beginning
● IntelliTrace, software transactional memory (STM) and Pex
● Isolation and White Box Unit Testing
● Workflow - CERT

17. Behind the Game

18. Behind the game - OS
● Linux OS Standardization (according to req)
● Additional security configuration for repository signatures
● LVM configuration - different schemes per server purpose
● FDE / Partition encryption
● Ulimits settings
● Kernel / Network stack tuning
● CPU and IO schedulers patches and tuning
Nice to read about: oomd, earlyoom, nohang

19. Behind the game - OS
● Spectre / Meltdown mitigations (retpoline)
● Latest CPU microcode
● Kernel mitigations
● GCC (fstack-clash-protection | mindirect-branch)
● Userspace (qemu / libvirt)

20. Behind the game - OS
Linux Security Modules (LSM)
AppArmor |
SELinux |
TOMOYO
LoadPin
Smack
Yama
SafeSetID

21. Monitoring
● Zabbix + Zabbix proxy + zabbix.dll (server integration)
● Zabbix autodiscovery for every HW server
● Vulns - CVE across installed packets - integration with Zabbix
● Kibana (ELK)
● Graphana
● Monit
● Graphite
● Graylog

22. Monitoring 2
● rsyslog (official repos, not distro)
● Logwatch
● Gitlab for all configuration files (both game and /etc)
● cachet (for status page)

23. HW / Net capacity tracking
● OpenDCIM - racks map and interconnection
● IPAM - IP Address Management
● Eramba - GRC (+compliance)

24. Compliance
● DISA STIG’s
● NIST SP (800x)
● SCAP / OpenSCAP

25. Access
● freeIPA
● Only SSH keys (elliptic curve)

26. Security (SOC and CSIRT / CERT)
● Wazuh
● Samhain HIDS
● Prelude
● GRR (Remote Live Forensics For Incident Response)
● Red ELK
● TheHive
● Chef InSpec

30. Network and network services
● DNScrypt
● NtopNG / Suricata
● iperf points
● PerfSonar “measurement island”
● NDT and speedtest
● ipsec (StrongSwan ESP) + hardware acceleration
● P2P (torrent)

31. Datacenter APIs

32. Datacenter API
How datacenter API should be provided (via official libraries):
● CLI
● Python
● Ruby
● Node.js
● PHP
● Go, etc...

33. Own integration
Something like:
● Flask, Flask-RESTPlus and Swagger UI

34. Datacenter API
Some unusual ways to use API:
● curl (testing only)
● Burpsuite / ZAP
● Metasploit module to interract with API

35. Datacenter Evaluation

36. Datacenter Evaluation
● PRICING QUESTIONS
● LOCATION QUESTIONS
● SPACE QUESTIONS
● NETWORK QUESTIONS
● POWER QUESTIONS
● COOLING QUESTIONS
● SECURITY QUESTIONS
● SUPPORT QUESTIONS
● CUSTOMER DEPLOYMENT QUESTIONS
● SERVICE LEVEL AGREEMENT QUESTIONS

37. Datacenter Evaluation
● ISO9001:2008, for quality management systems;
● ISO27001:2013, for information security;
● ISO14001:2004, for sustainability;
● PCI DSS 3.0, for information security for online payment;
● ISAE 3402 (comparable to SSAE 16) Type II, for service organization controls (SOC)
reports;
● IX Certified Data Center; for carrier-neutral colocation and interconnection.
● SAS 70 (Type 1 / Type 2)
● SSAE 16 (Type 1 / Type 2)
● SOC 1 / SOC 2 (Type 1 / Type 2) / SOC 3

38. Locations

39. Locations
Right near IX-points (AMS IX + Evoswitch DC as example)
Reliable datacenters
Close to users

40. Locations - Packet

41. Opennebula DDC
(Disaggregated Data Centers)

42. Opennebula DDC
A solution for:
1. Scalability (elasticity) problems
2. Human / configuration errors
3. Time save (big amount of data + configuration at once)
4. P2P
5. Best alternative for cold racks

43. Opennebula DDC
Scalability types:
1. Predictable (Events)
2. Mixed or Emergency
3. Unpredictable

44. Opennebula DDC
About predictable scalability
Metrics, Agreements, Formulas, ELK, Graphana, ingame analytics

45. Opennebula DDC
Mixed / Emergency scalability
Outages, including unplanned + urgent updates

46. Opennebula DDC
Unpredictable scalability
Fast grows and significant exceedances of expected statistical data

48. Provision
● Oneprovision
● Provision templates (YAML)
● IPAM Driver
