ISO 27002 is a standard which provides detailed description of security controls and how they need to implemented to provide effective ISMS.

SDN firewalls (e.g, security groups) can apply to assets based on more flexible criteria than hardware- based firewalls, since they aren't limited based on physical topology. (Note that this is true of many types of software firewalls, but is distinct from hardware firewalls). SDN firewalls are typically policy sets that define ingress and egress rules that can apply to single assets or groups of assets, regardless of network location (within a given virtual network).

Definitions:
SAST- Static application security testing(SAST) is a type of security testing that relies on inspecting the source code of an application. ln general, SAST involves looking at the ways the code is designed to pinpoint possible security flaws.
DAST- Dynamic application security testing(DAST) technologies are designed to detect conditions indicative of a security vulnerability in an application in its running state
