Security function investments, in general, are a balance between conflicting goals: Implementations vary widely, data for decisions is not readily available, and the market is intransparent with lots of claims and paperwork analyses. Therefore, the need for a realistic assessment of security solutions is crucial. Network threats and volumetric attacks are becoming more and more sophisticated and require a high level of confidence in a solution’s protection abilities.
Industries are challenged to select the right network security strategy and solutions for several reasons:
Internal threats matter too: While external risks are always a priority in data security, a potentially dangerous and insidious threat; an attack from within, is still ever-present. This can be caused by malicious intent or involved by careless negligence.
Network virtualization: Virtualized networks need to be protected by virtual firewalls. This is a question of the performance and functionality of the virtual firewalls in comparison with existing implemented physical appliances.
Different roles of network security solutions: Next-Generation Firewalls (NGFW) can act as an SSL-inspection, Intrusion detection, Anti-virus, or UTM. Therefore, security administrators need to carefully design and test the right solutions considering the functions and performance they need to play in the network.
