| what happens with technology | it changes at an increasingly rapid rate |
| describe the changes in the theory about keeping ourselves secure using technology and its advancements | Although technology changes at an increasingly rapid rate, much of the theory about keeping ourselves secure lags behind |
| how can you cope with security changes | if you can gain a good understanding of the basics of information security - gives strong footing to deal with changes in the field |
