In our previous blog, we explored some of the ways in which the increasing complexity of enterprise IT infrastructures – and the cyber threats they face – are bringing fresh challenges to the development and delivery of comprehensive IT security.
How, then, can organisations best protect themselves in this complex world?
The key principle to remember is that IT security for businesses today can no longer be a case of choosing a single, comprehensive security solution and deploying it across the infrastructure. Those infrastructures are too complex and too dynamic for that. When new IoT devices are being provisioned daily, when mobile devices are being taken off-premise and used to access the corporate system from 3rd party networks, when public and private cloud environments and 3rd party platforms are being used to deploy and access key business applications – the overall picture is multifaceted and multi-layered.
Security needs a co-ordinated approach at the network, the individual device and the application layer in order to provide comprehensive protection. It needs to draw on intelligence from a wide range of technical sources – as well as first-hand human experience – and it needs to work on both a proactive and a reactive basis.
Proactive IT security is focused on identifying and neutralising threats before they impact the business infrastructure. Threats need to be intelligently identified, filtered out and blocked. Applications should be patched and upgraded whenever necessary to ensure they are always working at optimal levels of security. Staff training and development is also a key element in proactive IT security, ensuring that your employees are aware of the threats you face and know how to recognise the most obvious signs of social engineering.
Reactive IT security, on the other hand, focuses on rapid isolation and remediation of any threats that do make it into your network. Incident response and disaster recovery processes are key – you need to know how to report and escalate incidents, and recover key data and applications should the worst happen. Again, staff awareness and training are vital.
