What is Network Design Project

Does your network diagram look like a plate of spaghetti? Do you even have a network diagram? In many businesses, networks grow haphazardly. First two devices get connected, then two more, then more, and eventually, it creates an unmanageable tangle of cables. If you haven’t rethought your network design in a while, now is a good time to take a step back and see if you can straighten out that mess. The first question to ask is, what infrastructure do you already have? This means pulling out any existing documentation to identify servers, switches, routers, and other connected devices. If you don’t have documentation, you may need to crawl around in the computer room and trace cable routes to see how things are currently working. Next, ask what demands your network needs to support. This means identifying the applications your users work with and the bandwidth those applications require. Your network likely needs to accommodate file servers and print servers along with dat...

Windows Help & Support

Windows 8.1 displays pop-up help tips by default to educate users on where to access functions such as the Charms and Start button. Although useful, the help tips can be annoying to experienced users who have performed a clean install of the operating system. To disable these tips, either change the registry settings associated with the help tips or edit the associated settings from the group policy editor. After altering the settings, you need to reboot your system for the changes to take effect. Regedit Step 1 Type "Regedit" (without the quotation marks) from the Windows 8.1 Start screen, and press "Enter." Step 2 Select "Yes" if prompted to confirm that you want to allow the program to make changes to your computer. Step 3 Click the small triangle next to "HKEY_Current_User" to open this root key, and then open the "Software" key. Step 4 Open the "Policies" key, and then open "Microsoft....

What is Security Architecture

Each type of information system platform (e.g., workstations, servers, storage area network, switches, firewalls, routers, virtualization, or cloud computing) that makes up the information technology infrastructure has its own unique vulnerabilities. Security architecture is fundamental to enforcing security policies that can be applied at different layers for each type of system platform. This architecture is based on how the enterprise will handle each of the following: Allowable and disallowable services and protocols Vulnerability scanning Patch management Firmware or software upgrades A security professional then sets standards for safeguards and controls for each platform. When designing the security architecture, a security architect or engineer should take the stance of an attacker to eliminate major vulnerabilities or reduce risks at each of the various platforms. This would entail a network engineer or security professional to use the same methods and t...

What is LM Compatibility

You might want to acquaint yourself with The Most Misunderstood Windows Setting of All Time. It’s the best written document on the relevant background for LMCompatibilityLevel. Review the NTLMv1 Known Problems and Workarounds for the most comprehensive resource available for the various problems associated with NTLMv1 being turned off. Note that NTLMv1 use can result from misconfigurations in a great number of places. And those misconfigurations can happen anywhere in the “authentication chain”. Misconfigurations can happen on the client endpoint, on a member server that provides the service the endpoint connects to, or any domain controller leveraged by the two. Most misconfiguration comes down to one of two things: the Windows LMCompatibilityLevel or browser configuration. If you are looking for the quickest way forward, we’d suggest using group policy to set a LMCompatibilityLevel=5 (“Send NTLMv2 response only. Refuse LM & NTLM.”) across all your computers. Doin...

What is Two-Tier Campus Network Architecture

To design and build a two-tier campus network architecture is everything like a three-tier hierarchical design and maximizes performance, network availability, and the ability to scale the network design. It is common to campus networks where the aggregation or distribution layer is merged with the core layer to create a unique and fully functional network for a good sized campus. However, many small enterprise networks do not grow significantly larger over time. Therefore, a two-tier hierarchical design where the core and distribution layers are collapsed into one layer is often more practical. A “collapsed core” is when the distribution layer and core layer functions are implemented by a single device. The primary motivation for the collapsed core design is reducing network cost, while maintaining most of the benefits of the three-tier hierarchical model.. To design and build a two-tier campus network architecture, a number of considerations must be taken into account. A k...
