Securing Your MongoDB Implementation
- 1. #MongoDBLondon Securing your MongoDB Implementation Mark Hillick - @markofu Engineer, 10gen
- 2. Agenda 1. Securing MongoDB 2.2 2. Securing MongoDB 2.4 3. Outside of MongoDB 4. Vulnerabilities 5. Documentation 6. Futures 7. Q & A Securing your MongoDB Implementation, Mark Hillick
- 4. Securing MongoDB 2.2 Authentication – Simple user/password scheme stored in MongoDB Authorization – Per database: no access, read, or read-write Auditing – Authentication requests logged – Some actions / changes captured in log Securing your MongoDB Implementation, Mark Hillick
- 5. MongoDB SSL SSL encryption SSL encryption for client for inter-server connection traffic Primary Secondary Application Data Files Data Files Keyfile establishes trust http://docs.mongodb.org/manual/administration/ssl/ Securing your MongoDB Implementation, Mark Hillick
- 8. External Authentication Use common / standardized authentication SASL: Simple Authentication and Security Layer – Framework for building authentication Kerberos – GSSAPI, drivers will be updated – Mixed system.users can work during transition Securing your MongoDB Implementation, Mark Hillick
- 9. Authentication with only pwd hash • Use one-way function F I am “marko@10gen.com”, let me in Knows Mongod only my Prove it, here is a random # N passwor d hash Here is F(N, hash(<mypwd>)) Nobody else could know Hash never that, welcome back marko! transmitted over the network! Securing your MongoDB Implementation, Mark Hillick
- 10. Authentication with Kerberos (2.4) I am “mark@10gen.com”, help me prove it to mongod KDC UDP:88 - Here is a TGT TCP:27017 Welcome, he Here is a re is a Kerberos Service TGT Ticket! UDP:8 8 Mongod { user: ”mark@10gen.com", roles: ["readWrite"], userSource: "$external" } Securing your MongoDB Implementation, Mark Hillick
- 11. Authenticating & Connecting # kinit mongouser …. # klist … 03/11/13 09:30:30 03/12/13 09:30:30 … # mongo mongodb.10gen.com/$external - -authenticationMechanism=GSSAPI -u mongouser@10GEN.COM Securing your MongoDB Implementation, Mark Hillick

Starting the Database env KRB5_KTNAME=/etc/kserver1b.keytab /usr/local/bin/mongodb/bin/mongod --auth --setParameter authenticationMechanisms=GSSAPI --dbpath /data/db --fork --logpath /var/tmp/mongod_auth.log --replSet realm4 --keyFile /etc/keyfile Securing your MongoDB Implementation, Mark Hillick
- 13. Authorization
- 14. AUTHORIZATION • Issues with 2.2 • 2.4 introduces roles – Admin level roles • UserAdmin – DB level roles • ClusterAdmin • User Admin • DB Admin • Read • ReadWrite
- 15. AUTHORIZATION Corresponding • Issues with 2.2 Admin level roles for AllDatabases – Only Read / ReadWrite – Edge-case with possible privilege escalation • 2.4 introduces roles – Admin level roles – DB level roles • UserAdmin • User Admin • ClusterAdmin • DB Admin • Read • ReadWrite Securing your MongoDB Implementation, Mark Hillick
- 16. ADMIN DB • ClusterAdmin • AllDatabases Source:https://wellsted135.files.wordpress.com/2012/10/special.gif Securing your MongoDB Implementation, Mark Hillick

Password Admin DB Accnts DB hashes • UserAdmin • UserAdmin • ClusterAdmin App DB Product • UserAdmi DB n • UserAdmin • dbAdmin • dbAdmin Customer • ReadWrite BI DB • • Read ReadWrite DB • UserAdmi • Read • UserAdmin n • dbAdmin • dbAdmin • ReadWrite • ReadWrite • Read • Read Securing your MongoDB Implementation, Mark Hillick
- 18. I can do anything but I won’t be I can add and required to do much remove shards DB Admin: UserAdmin DB Admin: ClusterAdmin I can I can grant I can create new create privileges to users but I can’t indices, set the App DB grant them profiling, co only privileges to other mpact DB’s DB Accnts: userAdmin DB App: userAdmin DB App: dbAdmin Securing your MongoDB Implementation, Mark Hillick
- 19. Super-User userAdmin & userAdminAnyDatabase are Only these users can view details about other users – system.users collection Securing your MongoDB Implementation, Mark Hillick
- 20. I can Each DB’s userAdmin gets to I can grant create grant privileges separately privileges to indices, set the App DB profiling, co only mpact DB App: UserAdmin DB App: dbAdmin In App.system.users : { { user: “fred” , user: “george” , usersource: “Accnts” , usersource: “Accnts” , roles: [ “userAdmin” ] roles: [ “dbAdmin“ ] , } Credentials from Accnts DB } Securing your MongoDB Implementation, Mark Hillick
- 21. Auditing
- 22. Additional Logging Monitor user activity: – userID added to standard output – Not currently a separate audit log – Much more coming in 2.6
- 23. Validation
- 24. Validation Objcheck – Helps prevent DOS – Validates input – SERVER-7769 (default) Securing your MongoDB Implementation, Mark Hillick
- 25. JS Engine
- 26. JS Engine Move to V8 – Primarily performance reasons but some security benefits – Restrictions on $where & M/R/F – SERVER-8104 & Aaron Heckmann’s Blog Securing your MongoDB Implementation, Mark Hillick
- 28. Outside of MongoDB Firewalls – iptables & netsh – Ports, Addresses, Times, Throttle etc F/S – Encrypt (Gazzang) Best Practices – Internal Policies (Password Reuse, Scan etc)
- 29. MongoDB - Gazzang • File System Encryption • 5% performance hit with HDD, 10-15% with SSD Gazzang Key Mgmt OS Gazzang File System – All contents encrypted Securing your MongoDB Implementation, Mark Hillick
- 30. Vulnerabilities
- 31. Vulnerabilities (1) Notify – Let us know How, What, Where? – http://docs.mongodb.org/manual/administration/vulnerabili ty-notification/ – Jira (HTTPS) & (Secure) Email Securing your MongoDB Implementation, Mark Hillick
- 32. Vulnerabilities (2) How do YOU know? – MongoDB Alerts How, What, Where? – Vulnerability Notification – Jira (HTTPS) & (Secure) Email Securing your MongoDB Implementation, Mark Hillick

Notes de l'éditeur
- Ok, so here are the presenters notes. Your first job is to add you name and other useful stuff so that your students can contact you afterwards.This is a good time to- introduce yourself- create a seating chart, get each student to say their name, company and what they want to learn... and write it on your seating chart
- system.users collection with hash password
- MongoD does not even need to know the password hash!You can centralize your authentication service – SPOF & SOS
- read: access to read documentsreadWrite: access to read and write documentsuserAdmin: manage, modify user access to a dbdbAdmin: compact, repair, validate etc.clusterAdmin: stuff with shards
- read: access to read documentsreadWrite: access to read and write documentsuserAdmin: manage, modify user access to a dbdbAdmin: compact, repair, validate etc.clusterAdmin: stuff with shards
- With SSD, as the time spent processing data between OS and disk gets proportionally larger since SSD's are so much faster, it means the pert hit is 15%. You still get a major upgrade in speed, but encrypting and decrypting take a larger share.
