Is software defined security changing security in modern applications? – By Aditya Abeysinghe Software defined security Software defined security (SDS) virtualizes security functions in a security network and abstracts it from hardware. It is not possible to virtualize every security aspect and hardware is necessary for some security functions in a system. Network functions including firewalls, intrusion detection, and access controls can be used in virtual networking with software defined networking and then added for SDS. Therefore, SDS has changed the use of security in networks by transitioning from traditional hardware to software-based components. Why transition to SDS? Network segmentation is used in networks to divide networks into sections so that one network section could separate from other sections. This reduces issues when one or more machines or virtual machines get attacked. When networks are segmented and when one section is attacked the other sections could operate without being attacked. ...
