This is according to Stefan van de Giessen, general manager: cybersecurity at Networks Unlimited Africa.
Van de Giessen says, “Security needs to have a layered approach, ensuring each level is protected with effective technology. A systematic, unified, layered posture ensures that all attack vectors are covered. An effective IT security ecosystem involves the holistic consolidation of tools and intelligence, and analytics should feature strongly in the technology deployed to protect the network.”
“Building a next-generation security solution should include various products that complement each other starting with perimeter protection; endpoint and secure email solution. Having these three is a vital start to your security posture. Once your baseline is established, we need to look at how we protect against unknown threats, encryption of your data and ultimately deploy decoys in your network to lure hackers off your network. We advise adopting a phased approach to developing a layered posture due to the cost and the complexity of management.”Van de Giessen outlines this phased approach as follows:
“It is never easy for an organisation to admit to a cybersecurity breach and we applaud City Power for its honesty in owning up to the reason for their systems outages, as well as for not paying the ransom demanded by the threat actors. At the same time, it should be noted that in being transparent, the organisation also acted according to compliancy principles as outlined by the European Union’s General Data Protection Regulation (GDPR) and South Africa’s Protection of Personal Information Act (POPIA).”
“The phased security posture advice outlined above applies to on-premise, cloud and hybrid environments. Additionally, device, operating system, software and policy updates should be carried out regularly and stringently to ensure no vulnerabilities can be exploited,” concludes Van de Giessen.
