Security Architecture in network level

 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 tools that a hacker might use to determine vulnerabilities.

Common DNS Issues

  Running into an error with the Domain Name System — simply called a DNS error — means you won't be able to get access to the internet, which is frustrating if it happens regularly. Learning the most common causes of DNS issues and the best methods for fixing them can help you get back online with minimal effort. Essentially the DNS translates the domain names we use to access websites into IP addresses, which is what your computer actually uses to access the website. In most cases, a DNS problem is easy to fix Network Problems In many cases, an error attributed to DNS could be a simple connection problem (especially if you're connecting wirelessly using a laptop) that doesn't really relate to the DNS at all.

How to disable SmartScreen in Windows 10 Creators Update

Windows 10 Creators Update introduced a number of changes to the user interface, so disabling Smart Screen can be a bit confusing. In this article, we'll see how to properly disable SmartScreen in it. The SmartScreen filter is a technology which was initially designed for Internet Explorer to protect users from malicious websites and web applications. It was integrated with IE8 and IE9 (as the successor to IE7's Phishing filter). Starting with Windows 8, Microsoft implemented Internet Explorer's SmartScreen feature directly into the operating system so files are screened for being potentially harmful. SmartScreen is also integrated for Windows Store apps. If enabled, the Windows SmartScreen filter sends information about every application you download and run to Microsoft’s servers, where that information will be analyzed and compared with their malicious apps database. If Windows gets a negative feedback about the app from the server, it will prevent you from running ...
