Cyber-attacks are a global phenomenon, with many Telecom organizations being routinely attacked. In the area of Malware attacks 40% of operators have reported incidents in the previous 12 months, it can be reasonably assumed that many more have actually been affected. The news of a wide range of cyber-attacks on Telecom is reported on a weekly basis. The increasing introduction of next-generation technologies used by Telco’s are, more and more, software-defined solutions which increase vulnerabilities and the probability of attacks. To counter these threats Telecom operators must adopt a holistic network security approach to effectively secure their infrastructure as well as the security of their customer. Security needs to be considered as part of the fundamental solution design across the entire network. A wise investment in cybersecurity will not only result in securing the Telecom organization but will also protect, and even create, new revenues.
