To work in cyber-security, flexibility and agility are key. The Chief Information Officer (CIO) or equivalent is responsible for managing and mitigating the risks of a cyber-attack, but these evolve constantly, not to mention increasing in size and ferocity as we trip towards a digital future. So too must a CIO evolve. More importantly, businesses must escalate the CIO's role and prioritise cyber-security to ensure survival.
GDPR and cyber-security
This year, cyber-firms – along with many others – have the addition of the fast-approaching GDPR (General Data Protection Regulation) to grapple with alongside their existing operations. The implementation date of 25 May is getting closer and many firms are not yet ready. For the CIO, it's important to understand how the new GDPR legislation will affect a business' cyber-security efforts.
There are two main areas that will need a change: the timeliness of reporting and the diagnosis of breach severity. From the end of May, a business suffering a hack or losing personal data must report it to the relevant Data Protection Authority within 72 hours of discovery. Lawyers will advise that minor breaches of non-critical data don't need reporting to the Information Commissioner's Office, but imagine if a superficially ‘minor' breach was a precursor to a more targeted, more damaging attack later on? Vigilance is crucial.
This means businesses – or more specifically, the CIO – must understand the activity within the corporate environment at an extremely granular level. They need to have systems that enable them to interpret the ‘signals from the noise' to indicate anomalous behaviour so evolving threats can be monitored. Real-time analysis at the network level is a means of achieving this clarity and understanding. Organisations need to understand the severity of a breach as underestimation could cause a breach to be reported too late, costing an organisation heavily in fines.
Responsibility for personal data
Another area that the CIO will likely take management of is the control and protection of personal data – this is at the core of GDPR. It is here that a business has an opportunity to inspire trust and reassure of authenticity to customers increasingly alert to their data privacy.
Understandably, the CIO will have limited resources to deal with this, so hiring a data protection officer is a smart solution. This role entails taking responsibility for reviewing and understanding held data. They will ascertain why the data is held, how permissions were gained and whom it will be shared with.
The data protection officer will also need the right tools in place to monitor irregularities and work with the wider network team. Real-time analysis at the network level will give businesses an indication of the files or data that have been transferred or viewed from the network environment. This will then support any breach reporting and give an organisation the means to handle the reputational aspect of a breach fallout, and rapidly understand what data has been accessed and how to respond.
Redefine the CIO
We know what a CIO needs to be responding to, but where are we starting from? Historically, IT Directors and CIOs were focused solely on operational activities: keeping the lights on, keeping risk low, keeping systems running. Today we are seeing a necessary transition of the role, from functional CIO to strategic CIO.
