Automation and offshoring have meant fewer technicians and cashiers, but lots more business analysts and systems architects.

自动化和离岸外包意味着更少的技术人员和收银员，但更多的业务分析师和系统架构师。

So system architects employ a strategy called defence in depth, which uses many layers of varying security mechanisms to frustrate attackers.

因此，系统架构师采用了一种称为纵深防御的策略，该策略使用多层不同的安全机制来挫败攻击者。
