Secure64 Software Corporationis a software development company headquartered inFort Collins,CO,USA, building server applications.
History
[edit]Secure64 was founded in 2002 and began full-scale development in 2005. Its founders include Bill Worley, CTO, a former chief scientist ofHewlett Packardand lead developer ofPA-RISCand PA-WideWord technologies. Secure64 has filed for severalpatents.[1][2][3]
Technology
[edit]SourceT Micro OS
[edit]The SourceT Micro OS executes on standardItaniumserver hardware, and provides the foundation for Secure64software applications.Secure64 uses the term "micro OS" to describe SourceT, because, although it shares attributes of traditionalmicrokernelsandmonolithic kernels,it does not fit the classical definition of either.
Like microkernels, SourceT adheres to the principles that minimal code should execute in kernel mode (currently less than 4,000 lines of code in SourceT), and that all applications and operating system services such asFile system,device driversandprotocol stacksshould not execute in kernel mode. However, like monolithic kernel architectures, SourceT's operating system services are accessed through system service calls rather than throughinterprocess communicationwith user-mode servers.
Unlike general-purposeoperating systems,which are designed to execute on a wide variety of hardware platforms, SourceT was specifically designed to take advantage of some of the unique security and performance features of the Itanium microprocessor to create a high performance, highly secure architecture. These unique Itanium features include:
- Completely independent read/write/execute privileges on memory pages
- Hardware controlled memory compartments with protection IDs
- Separation of control information from data on system stacks
- Inability to execute code from system stacks
- High performance frominstruction-level parallelism
Self-Protecting Network Stack
[edit]Secure64 has a patent pending for the queued, non-blocking and self-protecting communications architecture used by SourceT. Designed from the ground up with a queued, scalable architecture that differs significantly from a traditionalBerkeley socketsarchitecture, the network stack accelerates network I/O performance and automatically detects and drops malformed or flooding packets, such as those received as the victim of aDenial-of-service attacks.
Products
[edit]Secure64 DNSproducts aresecurity-hardened commercialDNSappliances,deployed on a proprietary64-bitoperating systemrunning onIntelItaniumhardware.Some of these products include:
- Authoritative DNS server,Secure64 DNS Authority
- Caching DNS server,Secure64 DNS Cache
- DNS Network Management,Secure64 DNS Manager
- DNSSEC,Secure64 DNS Signer
- DNS-based Network Security,Secure64 DNS Guard
