Step 1: Patch your system

The following steps apply to Microsoft Windows 2008 OS and Microsoft applications:

  1. Select the Start button
  2. Type “windows update” in the search area and press the Enter button.
    windows-update
  3. You should see the following screen:
    updates-available
  4. Select the Check for Updates option, which will connect to Microsoft to determine if your system requires security updates.
    check-for-updates
  5. Install security updates by pressing the Install updates button.
    Note: You may need to reboot your system immediately after you’ve applied the security updates.
    install-updates

Step 2: Rename the administrator account

Security Basics: 5 Steps to Tighten Security for Microsoft Windows

Tuesday, October 23rd, 2012 by

Security studies (including GoGrid’s internal research) strongly demonstrate that most systems will be attackedattack-in-5-hours within 5 hours after becoming publicly accessible—in some cases, in less than 2 hours. The sources of the attacks are often unsuspecting users whose systems have been compromised by malware and are in turn being used to attack and infect other systems. The majority of attacks target two common threats:

  1. A combination of commonly used system accounts (e.g., the Administrator account) with weak, dictionary-based passwords
  2. Systems that are missing critical or high-security vulnerabilities

Solution

This document provides GoGrid’s security recommendations for Cloud Servers running Microsoft Windows. Perform these 5 steps in sequential order immediately after provisioning new GoGrid Cloud Servers to maintain the integrity and security of your system.

Note: For a step-by-step how-to with screenshots, please see the companion article, “How To Tighten Up Windows Security.”

InformationWeek’s “IaaS Buyer’s Guide” with some Updated Information from GoGrid

Friday, October 19th, 2012 by

This week, InformationWeek published an extremely handy IaaS Buyer’s Guide designed to help companies navigate the complex airspace of cloud computing, specifically the Infrastructure-as-a-Service marketplace. The Guide covers 9 IaaS providers, including GoGrid, that each submitted responses to a questionnaire about their service offerings. InformationWeek then compiled and categorized those responses in this easy-to-understand Guide. You can find the full Guide (behind a registration wall) here.

InformationWeek-guide-cover

Topics covered in the Guide include:

  • CPU & Memory
  • Storage
  • Operating Systems
  • Database Software Needs
  • Redundancy/Data Center Needs
  • Additional VM Features
  • Cost
  • Security & Compliance
  • Support & SLA
  • Additional Services

A few things have changed since GoGrid was originally interviewed, and we wanted to provide updated information for some of these categories.

How to Install LAMP, Webmin & ConfigServer Security & Firewall on a CentOS 6.0 GoGrid Cloud Server

Thursday, July 19th, 2012 by

Let me preface this post by saying, I am NOT a Linux guru. In fact, I consider myself to be a newbie when it comes to the intricacies of Linux. I probably know enough to be dangerous, at least dangerous to the server. So, I’m writing this post with the following disclaimer: Don’t ask me for any details on the “why” or how to do what I’m outlining below differently. But since I figured that lots of you are like me, I wanted to share.

Since I’m a Linux newbie, you’ll probably understand why I wanted to write this post though. I’m not a command line junkie—GUIs are much more my thing. But when it comes to running a server that is speedy and high performance with low overhead (e.g., doing away with GUIs), you’re probably looking at various Linux distros. What I wanted to do was set up a basic Linux system running a LAMP (Linux, Apache, MySQL, and PHP) stack that also had a web-interface and some added security controls.

The great thing about doing this type of experimentation in the cloud is that I can create essentially a Dev & Test environment where I can spin up a server in minutes, install software, configure it, and test everything out. Then if it doesn’t work the way I want it to, I can tear it down and start again from scratch. The cloud lets you do this quickly, easily, and inexpensively.

In this tutorial, you can basically have the entire configuration up and running in the GoGrid cloud in less than an hour and only spend about $0.25 to test this out (assumes a 2 GB server running for 1 hour at $0.12/GB RAM/hr.)

Here’s what we’re using:

  • CentOS 6.0 (64-bit) – with 2 GB RAM
  • Webmin – web-based interface for sysadmins for UNIX that lets users set up user accounts, Apache, DNS, file sharing, and a whole lot more
  • ConfigServer Firewall & Security (CFS) – a Stateful Packet Inspection (SPI) firewall, login/intrusion detection, and security application for Linux servers
