NETWORK ENCRYPTORS: ESSENTIAL FOR THE PROTECTION OF SENSITIVE CUSTOMER DATA
FLYNT (Altoo) bank uses network encryptors and a cluster of Securosys Primus HSMs for its IT security. The company is protecting highly sensitive customer data. In his keynote speech at Securosys' Centurion Network Encryptor Launch, Stefan Thiel detailed the security requirements for FLYNT’s (Altoo) IT security architecture.
IT security is a top technology concern for the newly established FLYNT bank (Altoo). Flynt (Altoo) offers the possibility to aggregate data from different kind of assets within its platform: from real estate to banking assets held at different banks, from works of art to movable objects, such as airplanes or yachts. Therefore, the data of FLYNT’s customers (Altoo) are classified as highly sensitive. In addition, FLYNT (Altoo) has to comply with regulatory requirements for data protection and privacy like any other bank.
Two basic security requirements can be derived from this:
Protection of sensitive data from unauthorized access and manipulation
Operational protection, i.e. protection against intruders and ensuring the availability of online services
Some examples of appropriate security measures at FLYNT (Altoo):
Separate encryption of persistent data for each business entity in order to protect and separate stored data; FLYNT (Altoo) uses a cluster of Securosys Primus HSM for key management and encryption
Limitation of access to network, data and applications by means of specific authentication and authorization systems
A ready-to-use backup office location, this ensures the seamless continuity of operations in the event of a failure in one of the office locations
High availability data centers; two redundant data centers are linked redundantly in order to attain maximum availability of essential resources. Many services (such as storage, HSMs, VMotion, carp, VEEAM, Netscaler, Active Directory, Cassandra cluster and Akka cluster) synchronize with network encryptors. Therefore, the protection requirements for these links are particularly high.
Cluster or HA mode (1+1) für the most important hardware components. This applies particularly to network encryptors and the HSMs.
REQUIREMENTS FOR THE PROTECTION OF DATA-CENTER LINKS
FLYNT (Altoo) provides the following requirements for the protection of data-center links:
Network compatibility allowing to extend to other data centers and office locations in the future; therefore, the solution should support fiber, carrier Ethernet, MPLS and IP
Cost effectiveness in regard to long lifecycles and usage time, as well as multi-purpose capabilities (point-to-point or multipoint, various network technologies); for this reason, FLYNT (Altoo) opted for FPGA technology instead of an ASIC-based solution
Performance that does not reduce the actual bandwidth of the links (line rate forwarding and encryption); negligible latency which does not affect the communication of latency-sensitive systems (e.g., mirrored storage systems)
Maximum security level on the device, management, control and data plane; in addition, secure keys and secure key exchange.
Maintain local logs for compliance reasons; allow for secure integration into the monitoring infrastructure
No additional peripheral systems, which would generate further maintenance and safety cost
HARD-TO-COMPARE NETWORK ENCRYPTORS
“The evaluation of suitable devices proved to be a nightmare,” confessed Stefan Thiel.
During an online search one can find a lot of information about network encryptors. However, it is very difficult and time-consuming to compare technical data. FLYNT (Altoo) used a market overview of encryptors and hired its author as a consultant. The chosen solution has been in operation for two months now. „We are very satisfied,“ says Thiel.
With this technology, we are able to ensure a security level that fully meets the trust of our clients.
