1 Update for TF-Storage TF-Storage September 22nd, 2014
2 National Data Storage 2 Short reminder what is this about:
3 Security in Cloud? April 1, 2014 The Heartbleed bug Feb 26, 2014 Is catastrophic Safe enough!
4 Is AuthZ+AuthN enough? AuthN / AuthZ Cryptography
5 We need cryptography! RSA-4096 AES-256 SHA-512
6 Cryptography is NDS2 RSA-4096 MASTER KEY PAIR AES-256 PER-FILE AES-256 PER-FILE AES-256 PER-FILE
7 Cryptography is NDS2 decrypt (open the secret case) user s private directory s private ABC encrypt (lock the secret case) user s public directory s public file s symmetric unencrypted file decrypt (open the secret case) user s private group s private directory s private ABC encrypt (lock the secret case) user s public group s public directory s public file s symmetric unencrypted file
8 Cryptography?
9 SECURE DATA SYNCHRONISATION & STORAGE & ACCESS TOOLS ECOSYSTEM OPENNESS
10 Drive
11 Security vs efficiency Virtual disk for Windows bulk transfers
12 Data sync & virtual disk together User s home Archives HPC input data Sync Docs Spreadsheets Pictures HPC outputs
13 National Data Storage 2 Status: - In the beta phase - Clients available for download: + nds.psnc.pl/download - Code to be open soon (being moved to github) - Continuous integration etc. on the way - Presented and demo-ed at TNC Users: + Internal users mainly + Some external users: > clinical hospital, some universities + Rollout planned, but still sth to do - Why won t you use it? - Testers welcome!!!
14 National Data Storage 2 Latest developments (1): - LCFS Loopback/Local Crypto File System: + stores encrypted data in the local filesystem + enables usage of encryption on top of ANY local or networked storage + Windows version available + Linux version on the way + works with: - FAT/NTFS - samba / CIFS - NFS - Dropbox! and other clouds (e.g. Google Drive)
15 National Data Storage 2 Latest developments (2): - LCFS WHY? + we wanted to facilitate integration of NDS2 functionality with existing stuff + some storage providers does not support SFTP + SFTP introduces relatively high latency: => while OK in WAN (main application) => some other protocols perform better in LAN
16 National Data Storage 2 Latest developments (3): - Windows Phone client + re-uses some part of regular NDS2 Windows client => encryption / integrity control => SFTP client + status on the way, should be available 1Q WHY: > a lot of managers uses Windows Phone at least in Poland ios not that popular (real-life observations, confirmed by telcos) + challenges: > dealing with certificates, encryption > interface to be developed from scratch to match platform specifics
17 National Data Storage 2 Latest developments (5): - LDAP and Active Directory integration + running in some deployments > e.g integrated with PSNC s LDAP + proof of concept: > prepared AD PoC for large user
18 National Data Storage 2 Roadmap: - Go on with stabilizing the code - Further internal tests and beta-tests with users - Improving documentation + website + e.g. movies with how-tos + whitepapers explaining the details and security aspects - Possibly tests with TF-Storage partners + don t you care security? + tell us what s wrong with our solution? (we would be happy to argue)
19 National Data Storage 2 Roadmap (2): - NDS2 version 2 + more symmetric, less asymmetric cryptography for simple cases: > better performance with many files (less latency) > bulk transfer/encryption already acceptable + paranoic-mode options (less trust on servers) > stronger data vs meta-data integrity protection > client-side cryptography-based access control > write non-repudiability > write signing / verification
20 National Data Storage 2 Roadmap (3): - Storage and AAI + need to attack the problem > not a trivial task > several approaches exist but not obvious where to go + take up existing solutions?
21 National Data Storage 2 Roadmap (4): - Web interface? + we re examining some solutions: > testing / trying pydio > evaluating in-browser encryption options
22 National Data Storage 2 Lessons learnt: - Way from prototype to product: + 2x the way from idea to prototype - Real life verifies the solutions the best: + some ideas / mechanisms to be dropped + the more complexity/components the worse ;]
