As a chief information security officer (CISO), it’s my responsibility as a senior executive to ensure the protection of an organization’s information systems and assets from internal and external threats by developing an information security program and ensuring its compliance. My main focus as a CISO is protecting data and networks against cyberattacks, which comprise the confidentiality, integrity, and availability of an organization’s data, thus weakening its information security.
Availability of data is one core element of the CIA Triad, confidentiality, integrity, and availability; the CIA Triad is a modeled approach in developing an information security program (Chai, 2023). Availability is critical for an organization to be reliable and ensure successful daily operations; therefore, to protect the availability of my organization’s data, I will implement a data backup, ensure data systems are kept up to date, and implement access controls. The data backup will be accomplished via Cloud storage. Cloud storage is a third-party provider that backs up data to cloud-based servers remotely (IBM, n.d.). Ensuring data systems are kept up to date on a regular basis prevents vulnerabilities from existing for an extended period of time and allows for security flaws to be patched, thus preventing attackers from compromising the system and ensuring data availability.
Implementing access controls is a security measure that will ensure authorized personnel are accessing the data, which can be accomplished through authentication and authorization. Additionally, implementing access controls contribute to the confidentiality and integrity of data, encompassed in the CIA Triad. The access control system will be a two-factor authentication system. It will require a username and pin to prove the identity, or authorization of the user, and a one-time access code sent to their mobile device to authenticate the user. Many additional implementations exist to ensure the availability of data, such as firewalls, however, as a CISO, I will implement data backup via cloud storage, ensure up-to-date systems, and implement access controls to achieve data availability within my company.
