MongoDB and Red Hat have collaborated to deliver an integrated solution for securing MongoDB deployments. Red Hat's proven security infrastructure adds extra protection to MongoDB with standards-based identity management featuring centralization of user, password, and certificate information. MongoDB and Red Hat team members present what you need to know to secure your systems, including an overview of Red Hat's Identity Management in Red Hat Enterprise Linux and MongoDB-RHEL security architecture.

Securing Your Deployment with MongoDB and Red Hat's Identity Management in Red Hat Enterprise Linux
- 1. 1 Securing MongoDB with Red Hat Enterprise Linux Identity Management Jim Wildman, Solutions Architect, Red Hat Sandeep Parikh, Solutions Architect, MongoDB
- 2. 2 MongoDB The leading NoSQL database Document Database Open- Source General Purpose
- 3. 3 MongoDB Features • JSON Document Model with Dynamic Schemas • Auto-Sharding for Horizontal Scalability • Text Search • Aggregation Framework and MapReduce • Full, Flexible Index Support and Rich Queries • Built-In Replication for High Availability • Advanced Security • Large Media Storage with GridFS
- 4. 4 • Enterprise authentication using Kerberos • In-flight encryption using SSL • On-premise management tools for monitoring • On-demand private training • Integration with SNMP • Certified for Red Hat Enterprise Linux MongoDB Enterprise Features
- 5. 5 • Identity, Policy, and Audit services • Integrated security management solution – Authentication – Directory Services – Encryption – Client/Server Discovery – Systems Management • Available via – Red Hat Enterprise Linux 6.4 – FreeIPA Red Hat Identity Management
- 6. 6 Red Hat Identity Management
- 7. 7 Security Considerations Authentication • Identity assurance • SSO Authorization • Role-based • Privileges • Permissions Auditing • Identity logging • Governance reporting Administration • Identity provisioning • Change control Encryption • Data at rest • Data in motion
- 8. 8 Security Implications Authentication • Apps accessing DB • Nodes joining cluster • Admins accessing DB Authorization • Apps DB permissions • Admins DB permissions Auditing • Who logged in Administration • Create users • Manage user policies Encryption • Encrypting data in-flight
- 9. 9 Security Architecture Identity • AD • LDAP • Etc. Clients • MongoDB • App Servers • Web Servers
- 10. 10 RHEL IdM Architecture • Accounts, credentials, policies are centrally located • Clients authenticate users and services via server as-needed
- 11. 11 RHEL IdM Replication • RHEL IdM natively supports multi-master replication • One user name space across all data centers and replicas
- 12. 12 • Lack of centrally managed identities creates security and compliance problems • More secure host connections (no passwords in text files) • Host-based access control provides centralized, fine- grained access • Centralized “sudo” management • Private user groups allow for better security at the file level • Kerberos authentication has strong security characteristics – Password never leaves the client, hashes are strong Security & Compliance Enhancements
- 13. 13 IdM Server Setup # install IdM packages $ yum install ipa-server bind bind-dyndb-ldap # set hostname $ nano /etc/sysconfig/network HOSTNAME=idmserver.example.com $ hostname -v idmserver.example.com
- 14. 14 IdM Server Setup # run IdM installation $ ipa-server-install --setup-dns # add IdM server DNS $ nano /etc/resolv.conf nameserver [IdM server IP address] # authenticate as admin via Kerberos $ kinit admin # list active authentications $ klist
- 15. 15 IdM Client Setup # install IdM client and tools $ yum install ipa-client ipa-admintools # update hostname $ nano /etc/sysconfig/network HOSTNAME=idmclient.example.com $ hostname –v idmclient.example.com
- 16. 16 IdM Client Setup # point DNS to IdM server $ nano /etc/resolv.conf search example.com nameserver [IdM server IP address] # automatically enroll this machine into IdM $ ipa-client-install --enable-dns-updates Discovery was successful! Hostname: idmclient.example.com Realm: EXAMPLE.COM DNS Domain: example.com IPA Server: idmhost.example.com BaseDN: dc=example,dc=com
- 17. 17 IdM Client Setup # ex. reverse addr: 243-16-164-10.in-addr.arpa. # add a reverse-DNS zone $ ipa dnszone-add [idmclient-reverse-addr] --name-server idmserver.example.com. --force # add a reverse-DNS record $ ipa dnsrecord-add [idmclient-reverse-addr] [record-name] --ptr-hostname idmclient.example.com.
- 18. 18 • MongoDB deployed on RHEL IdM clients • Leverages authentication and encryption services – Kerberos – SSL • Map MongoDB users/roles to Kerberos principals • Encrypt connections – Amongst MongoDB nodes – Between MongoDB and clients Deploying MongoDB with RHEL IdM
- 19. 19 MongoDB Kerberos Setup # add a service principal to IdM $ ipa service-add mongodb/idmclient.example.com@EXAMPLE.COM # retrieve the MongoDB keytab file $ ipa-getkeytab –s idmserver.example.com -p mongodb/idmclient.example.com -k /etc/mongodb.keytab # verify keytab $ klist –k /etc/mongodb.keytab
- 20. 20 MongoDB Kerberos Setup $ env KRB5_KTNAME=/etc/mongodb.keytab mongod --fork --auth --dbpath /data --logpath /log/mongod.log --setParameter authenticationMechanism=GSSAPI
- 21. 21 MongoDB SSL Setup # issue server certificate request $ ipa-getcert request -r -f /etc/cert/mongodb-server.crt -k /etc/cert/mongodb-server.key -N CN=idmclient.example.com -D idmclient.example.com -K mongodb/idmclient.example.com # Note: -D and CN must match MongoDB hostname and –K must match service principal
- 22. 22 MongoDB SSL Setup # cat key and cert into pem $ cat /etc/cert/mongodb-server.key /etc/cert/mongodb-server.crt > /etc/cert/mongodb-server.pem # start mongod with PEM and IdM CA $ mongod --sslOnNormalPorts --sslPEMKeyFile=/etc/cert/mongodb-server.pem --sslCAFile=/etc/ipa/ca.crt
- 23. 23 MongoDB Client SSL Setup # issue client certificate request $ ipa-getcert request -f /etc/cert/mongodb-client.crt -k /etc/cert/mongodb-client.key # cat key and crt into pem $ cat /etc/cert/mongodb-client.key /etc/cert/mongodb-client.crt > /etc/cert/mongodb-client.pem
- 24. 24 MongoDB Client SSL Setup $ mongo --ssl --sslPEMKeyFile=/etc/cert/mongodb-client.pem --sslCAFile=/etc/ipa/ca.crt
- 25. 25 • Each component will need a service entry and keytab – In a replica set, each mongod – In a sharded cluster, each mongod and mongos • Verify Kerberos settings using built-in k-command – E.g. “klist” • Network configuration impacts authentication – Hostnames must be set and should be consistent – DNS/reverse-DNS and routing must be correctly set up MongoDB and Kerberos
- 26. 26 • IdM Certificate Authority provided as part of certificate requests • IdM Certificate Authority can be root or act as subordinate to external CA • Certificate management daemon monitors expirations and can auto-renew certificates MongoDB and SSL

Editor's Notes
- MongoDB provides agility, scalability, and performance without sacrificing the functionality of relational databases, like full index support and rich queriesIndexes: secondary, compound, text search (with MongoDB 2.4), geospatial, and more
