4.1 - 5 levels of Backup
In the unlikely event of data loss, your SASSIE Hosting and Maintenance fee includes 5 levels of backup in 3 geographical locations, and can often get you back up and running in minutes:
- SQL hot replication - each SQL server has a "twin" that keeps an up-to-the-second copy of all of your data. In the event that your primary database server goes offline, the twin will take its place, ensuring that you never lose data due to server malfunction.
- RAID-5 drive configuration - With a RAID-5 configuration, two copies of your data are accessible at all times on EACH server.
- Nightly backups to separate server - every night, a full copy of your data is backed up.
- Weekly offsite backups to separate server - every week, a full copy of your data is backed up to a server at a second location outside of our hosting facility.
- Weekly offsite backups to DVD-R - every week, a full copy of your data is burned to DVD-R and housed at a third location outside of our hosting facility.
4.2 - RAID 5 with instant recovery and dual power supplies in each server
The most common server failures are due to hard drive crashes and power supply meltdowns.
- RAID-5 configurations guard against hard drive failure in two ways:
- Two copies of your data are accessible at all times
- Each server has three hard drives instead of one
- If any hard drive fails, the others will immediately take over and continue normal operations.
- RAID-5 is typically an upgrade that would cost you thousands of dollars to have installed on your system. With SASSIE, you receive this service for free.
- Every SASSIE server has dual power supplies, so if one fails, your service won't be interrupted.
4.3 - 4 Way Physical Protection
These days, we need to know that our data facility has all the necessary physical safeguards.
SASSIE's facility has the following protections:
- Fire - Our facility features a VESDA fire detection system and is equipped with dry sprinkler systems to provide early fire detection and server-safe fire suppression (conventional water sprinkler systems can short circuit and damage your servers).
- Power - SASSIE's hosting facility receives power from two different power utility plants, meaning that two cities must lose their power before SASSIE loses electrical service. Even then, four one-megawatt generators are in place to provide 150% of the backup power needs in the event of total power failure.
- Unauthorized entry - Biometric recognition systems and 24/7 4-man security personnel prevent entry by unauthorized personnel.
- Environmental - SASSIE's facility has a fully redundant Leibert HVAC system, which maintains temperature and humidity to rigid standards.
4.4 - Load Balanced Server Architecture
Will system performance be consistent during the busiest time of the day?
Our data center features a "load balanced" architecture that delivers fast and stable performance, even under the most extreme conditions. We utilize multiple redundant web servers and database servers so that your system will remain operable even if a server goes offline or reboots.
Furthermore, multiple state of the art "load balancers" route traffic to the least busy web server (or database server) guaranteeing optimal performance even during the heaviest of traffic. We're confident that our data center represents the ultimate cutting edge in the mystery shopping industry.
Our hosting facility also guarantees 99.9% uptime and has multiple backup internet connectivity - if one line goes down, your traffic will be rerouted to other lines instantly without your clients ever knowing.
Six tier one providers have fiber installed into the facility:
- Cable and Wireless
- Genuity
- Global CrossingSprint
- Verio
- WorldCom/UUNet
4.5 - Unix Server Security (Virus Protection – NOT Microsoft Servers)
SASSIE runs on Unix Servers, not Microsoft Servers which are notorious for their vulnerabilities to hackers and viruses (such as the Slammer Worm which infected thousands of Microsoft SQL database servers in early 2003). SASSIE's network is also protected by a front end firewall to prevent unauthorized access to SASSIE's servers.
4.6 - Separate Database and Web Servers
Your SASSIE system sits on two servers - one to handle your web pages, and one to handle your databases. Your database server is NOT directly connected to the internet and can only be accessed by SASSIE web servers, a huge layer of security against would be hackers trying to alter or steal your client's data.
4.7 - Individual User Logins
Sharing of user accounts is a serious security issue. SASSIE can create a separate account for every staff member, client manager, scheduler and shopper who uses the system and gives you extremely tight control over their viewing privileges and administrative privileges. There are over 40 different privileges that can be turned on or off for each individual (reviewer access, scheduler access, billing access, access to certain clients only, etc...).
4.8 - SSL Encryption of Shopper Personal Data
Our shoppers are concerned about entering personal information over the website.
On SASSIE, shopper signups take place on a secure SSL layer (the kind used by online credit card transactions) which encrypts the transmission of their data. Your shopper's browsers will notify them that they're entering a secure site when they sign up or edit their personal data. Also, sensitive information like Social Security numbers are kept in encrypted format in the databases themselves - even if someone were to steal the databases themselves, they would not be able to read the encrypted data.
4.9 - 24/7 Server Monitoring
How do you know if our system is down? Do we need to notify you?
Monitoring software checks each of SASSIE's servers every few minutes, and sends electronic pages to at least 5 of our staff if the servers are unresponsive.
4.10- Logins expire after a period of inactivity
Another security issue occurs when a user walks away from their computer and forgets to log themselves out, leaving a live connection open. SASSIE detects when an account has been inactive for an unusual amount of time and logs that account out automatically. Don't use a system that relies on every shopper, client and staff member to log themselves out every time!
