多年来,安全专家一直在争论究竟是外部人员还是内部人员带来更大的风险。如今,这种辩论已经没有实际意义:因为网络界限已经模糊化,威胁正无处不在。例如,内部人员可能在家里办公或远程办公;员工可能需要利用BYOD;业务合作伙伴和销售人员经常需要访问云中关键任务服务。现在企业比以往任何时候都更难了解在给定的时间内谁在网络上,以及有多少设备在访问服务、系统和数据。 For years, security experts have been debating whether external or internal staff poses greater risks. Today’s debate is no longer relevant: the threat is everywhere because of the blurring of the network boundaries. For example, insiders may be working from home or telecommuting; employees may need to leverage BYOD; business partners and salespeople often need to access mission-critical services in the cloud. Now businesses are harder than ever to understand who is on the network, and how many devices are accessing services, systems and data at any given time.
