Syscall 7 knows software security.  We have experience analyzing software and systems to identify vulnerabilities and security weaknesses that place these systems at risk for malicious intrusion. This includes both system level software and application software in Windows, Linux, and other proprietary operating systems. We also have experience in analyzing medical devices, critical infrastructure devices, industrial control systems, and SCADA (Supervisory Control and Data Acquisition) systems for vulnerabilities and recommending techniques and methods for mitigating the risks posed by the weaknesses uncovered.

Syscall 7 provides custom computer software development at all levels of the software stack. We have expertise developing at the low level assembly level for architectures such as intel x86, MIPS, PowerPC, ARM, NIOS II, and Microblaze. We also specialize in system-level C and C++ development for custom embedded systems as well as traditional desktop and server-based systems. We have experience programming network-oriented software that makes use of both custom and standard network protocols built on Ethernet, IP, ICMP, TCP, UDP, HTTP, and others. We have developed custom network protocol dissector plugins for network analysis engines such as Wireshark.

We have developed for many different operating systems including Windows, Linux, FreeBSD, and other real-time embedded operating systems such as VxWorks. Our expertise extends to writing Graphical User Interfaces (GUIs) in high level programming languages such as C# and the Microsoft .NET runtime. We have also developed low level kernel drivers in Linux. Our favorite scripting languages are Python and Ruby, but we also have experience in other scripting languages such as bash, lua, tcl, and perl. We are familiar with a variety of source revision control systems including StarTeam, Subversion, and git. Our software development approach is based on Scrum, an Agile software development framework that is both flexible and outcome based.
