    Web Site/Web Store Design, Development & Performance Tuning

    Want to establish an internet presence? Our development team has designed, developed and delivered secure, n-tier e-business trading sites and information portals based upon AJAX, Java, Microsoft web technologies and Windows/Unix-based platforms. The systems' architectures supported secure multi-million dollar transactions and included customized user interfaces for international B2B customers (language, localization). Other web applications and information portals included complex business logic, multi-media presentations, real-time video streaming, instant messaging and secure email capabilities.

    Want a web store front? Our designers have developed several retail-based web stores on Amazon, Froogle, NexTag, Pricegrabber, Shopping.Com, Shopzilla, Yahoo! Shopping and other eCommerce sites. These web stores allow a small business to establish an instant 24 hour, 7 day a week presence on the Internet. Most importantly, we optimize the web stores for the major search engines, providing your web store with a high search ranking and overshadowing your competition.

    Current web site/store slow to load? Need a new look? Our web engineers have analyzed numerous slow web sites and provided faster performance solutions. We can also redesign your current web site/store to support easier navigation, better customer visibility on the web, improved visual appeal, faster loading web pages, smarter email autoresponders, etc. This can be accomplished with your current Internet Service Provider (ISP) so you do not lose your current capital investment or sunken costs. Please visit our Web Features & Pointers checklist to consider design options for your web site or web store. Also, please view some of our web site designs here!

    Information Security & Protection

    How vulnerable are you? Web-based applications are the weakest link regarding information security. They are being exploited by hackers to gain access to sensitive personal and corporate data. Some of the common attacks are SQL Injection, Cross Site Scripting, CRLF Injection, Directory Traversal, Authentication Hacking, Rootkits, Phishing, Kernel Mode Payloads, and Google Hacking. For other ongoing computer hacking and virus trends, visit the Black Hat Archives and Security Focus pages. Hackers are concentrating their efforts on attacking website applications: 75% of cyber attacks are launched on shopping carts, forms, login pages, dynamic content, etc. Web applications are accessible 24 hours a day, 7 days a week and control sensitive data such as customer details, credit card numbers and proprietary corporate data. Firewalls, SSL and locked-down servers are futile against web application hacking. Any defense at network security level will provide no protection against web application attacks since they are launched on port 80 – which has to remain open. In addition, web applications are often tailor-made, therefore tested less than off-the-shelf software, and are more likely to have undiscovered vulnerabilities.

    How do you protect your data and intellectual property? The key is a layer-in-depth approach. Our engineers keep abreast of the latest security technologies, including the many emerging security standards. We have designed and developed multiple level security into systems using security software, scripts, proxy servers, deep packet inspection firewalls, DMZs, biometrics, smart cards, PKI, SSL and IPSEC encryption, LDAPs, ASP.NET and JSP application software, SMIME, Single Sign On (SSO) systems, Virtual Private Networks (VPNs), VLANs, wireless mobile devices, wireless encryption, and Oracle virtual private databases. We have also designed a multiple layer security architecture for web-based student information systems using data warehouses. The systems protected an individual's Personally Identifiable Information (PII) and conformed by federal law and state statutes regulating privacy information. We also authored draft privacy policy guidelines for state organization implementation. We support customer's security requirements in the following CISSP Common Body of Knowledge (CBK) domains: Information Security Management; Security Architecture and Models; Access Control System and Methodology; Applications and System Development; Operations Security; Cryptography; Physical Security; Telecommunications, Network and Internet Security; Business Continuity Planning; and Law, Investigations, and Ethics. Our team performs discreet vulnerability assessments and port scanning of your present system. This process identifies potential weaknesses that hackers and identity thieves can exploit. We then provide recommendations and solutions on how to protect against these weaknesses.

    Is your wireless network truly secure? If you have recently installed a wireless or Bluetooth network, you may be surprised how vulnerable your company confidential data is. Many wireless access points and configurations are completed without "locking down" the network or using encryption technology. This situation enables hackers to obtain information (e.g., usernames, passwords, sales data, confidential reports, etc.) and exploit the company's network. We can help you secure your wireless network to prevent this potential security breach.

    System/Network Analysis, Design & Development

    Can not decide between different architectures? Our in-depth knowledge of competing technologies enable us to propose different system/network architectures, design principles, and design patterns. We also have expert knowledge in distributed object development on multiple platforms. We always identify architecturally significant requirements and their ramifications to make engineering tradeoffs between conflicting requirements. Also, we have architected and deployed multiple applications within a single system and/or product suite. Object-oriented development is used whenever possible. Mastery of abstraction, encapsulation, inheritance, polymorphism allows us to design flexible and enduring systems. These skills are performed at the application/component/package/module level.

    Which network to choose? We have been involved with network technology for over 25 years. This includes different topologies, architectures, standards, mixed-technology, etc. Some secure networks we have designed included multiple protocols, long haul networks, and various modulation techniques. These include terrestrial lines, satellite, microwave, infrared, wireless, and spread spectrum.

    System seems sluggish? Performance enhancement is key to overall customer satisfaction. We can tune your systems and networks to obtain optimal performance. We use various network performance and computer performance analysis tools to determine the sluggish response. We then tune the appropriate parameters (buffers, timeouts, message length, etc.) to improve the network/system performance.

    Custom Hardware/Software Design & Development

    Have a special project not available from off the shelf technology? Our engineers have experience with imbedded systems, application software, mobile devices, device drivers, interrupt handlers, special input/output devices, unique sensors, and real-time operating systems. Our development efforts have produced many one-of-a-kind systems that customers needed. These systems varied from standalone computers to 120 single board computers distributed across different geograpical locations. We also design prototype systems for customers. If you have a great idea, let our engineers develop a working prototype for you. One-of-a-kind systems are our forte and we welcome the technical challenge!

    Virtual Reality and Simulation

    What kind of virtual reality and simulation experience? Our engineers have over 25 years of "hands on" experience defining, designing, developing, deploying, and maintaining distributed simulation systems with different design and development methodologies/tools. Simulation systems include flight simulators, ALSP/DIS/HLA/RTI protocols, DIS-based simulators, distributed architectures, complex simulation models and algorithms, real-time messaging performance, multiple protocol networks, 3D visual systems, 6 DOF motion systems, custom device drivers, secure networks, multi-vendor platforms, symmetrical processing, embedded systems, distributed databases, multi-tier web technologies,and multiple lingual interfaces. We have supported some of the largest distributed simulation exercises in the world.
