FireEye releasedMandiant? M-Trends? 2018 report, sharing statistics and insights gleaned from Mandiant investigations around the globe in 2017. FireEye has discovered that organizations which can detect breaches internally are doing so faster, with median duration between the start of an intrusion and it being identified decreased to 57.5 days in 2017 from 80 days in 2016. However, the global median dwell time before any detection -external or internal- rose to 101 days in 2017, from 99 in 2016. The data provided in the report shows that organizations which have been victims of a targeted compromise are likely to be targeted again by the same or a similarly motivated attack group, with 49 percent of customers successfully attacked again within one year. The demand for skilled cyber security personnel is continuing to rise, but the supply is not keeping pace, and the skills gap is affecting two areas: visibility and detection, and incident response.
