Well the answer is that they are layered like onions.  Here are 7 layers all businesses should have in place so that if one layer is compromised then the other layers will deal with incoming threats.

1. Social engineering
   • have processes in place to verify e mailers or callers when they are asking for sensitive information
2. Physical security
   • we concentrate on virtual systems all the time that we often overlook the physical aspect
   • make sure your server is locked away
   • don’t leave usb keys or passwords out on display
3. Wireless security
   • another overlooked aspect as wifi signals often extend beyond our walls
   • make sure the router is not using a default password
   • don’t use antiquated protocols such as WEP or WPA
4. Passwords
   • passwords should be complex and not used across accounts
   • using a password management tool like LastPass will help
5. Two-factor authentication
   • a lot of systems support two-factor authentication which will help protect your account
   • check the settings on your critical accounts to see if you can setup two-factor authentication
6. Email security
   • you should never click links or open attachments on emails
   • make sure to have spam and phishing filters in place
7. Anti-virus
   • the last line of defence but also with its own vulnerabilities
   • consider using a product that supports application whitelisting and device control

A digital copy of a song is around 5mb. This is a picture of 5mb hard drive being moved in 1956. These days hard drives are a lot smaller and a lot cheaper to move. We always recommend using fast SSD drives in the computers we sell. If you are in need of a technology refresh then get in touch.
