Published today in CSO – some insights from me on the recent AT&T breach as well as a stat from the Data Exposure Report.

“The recent AT&T breach highlights significant insider risk factors related to the unauthorized access and exfiltration of call detail records,” Dennis Dayman, CISO of Code42 Software, told CSO.

“While cyber threats are ever-evolving, the risk imposed by the human element remains a constant,” said Dayman, whose company provides insider risk protection. “Insider risk is one of the biggest security challenges posed by the unpredictable nature of employees, partners, and contractors who are trusted to handle sensitive corporate data and IP daily.”

According to Dayman, such risks might not initially appear to be a high priority, but they can quietly proliferate, causing downstream consequences. “Though insider risk is not new, it has become more prevalent over the past few years with the inception of remote-first distributed workforces, increased use of collaboration tools, and high-risk digital behaviors.”
