The vast majority of CISOs have observed positive security culture gains in their organizations in the last year despite a perceived dip in the quality of overall security posture, according to the 10th annual Information Security Maturity Report published by ClubCISO and Telstra Purple. The research surveyed 182 members of ClubCISO, a global community of information security leaders working in public and private sector companies. The paper paints an optimistic picture of organizational security with CISOs reporting a drop in reported material breaches compared to the year before, while 60% state that leadership endorsement has been a major influence in improving organizational security culture.
