Financial management skills: Ability to manage the information security budget effectively and demonstrate the ROI of security investments.
Compliance knowledge: Understanding of relevant regulations and standards and ability to ensure compliance.

Example: A CISO must understand how a new cloud service being adopted by the marketing department could introduce new data security risks. They then need to communicate these risks to the marketing team in a way that the team understands and can participate in a collaborative mitigation strategy.

The Evolving Threat Landscape and Challenges for CISOs

The threat landscape is constantly evolving, with new threats emerging every day. CISOs face a number of challenges in keeping their organizations secure.

Emerging Threats

Ransomware: Ransomware attacks are becoming increasingly sophisticated and targeted, causing significant financial and operational damage.

Phishing: Phishing attacks remain a persistent threat, targeting employees with deceptive emails and websites.

Supply chain attacks: Attacks targeting suppliers and vendors are becoming more common, allowing attackers to compromise multiple organizations through a single point of entry.

Cloud security threats: Misconfigured cloud environments, data breaches in the cloud, and insecure APIs are emerging as major security risks.

Insider threats: Malicious or negligent insiders can pose a significant risk to organizations.

Challenges

Skills shortage: There is a global shortage of skilled cybersecurity professionals, making it difficult to recruit and retain talent.
