Applying preventative risk reduction
Wherever it is possible, we will look to use prevention to protect our data and information systems. Preventative technologies will offer a solid base that we can build on. In most cases, a standard operating environment (SOE) will offer many security benefits. SOE allows us to deploy operating system images that can be measured against a baseline and then further enhanced with additional security add-ons. In this section, we will look at some preventative technologies.
Antivirus
Antivirus tools are an important preventative solution. They can be deployed on end devices and on network gateways, such as next-generation firewalls (NGFWs) and unified threat management (UTM). The latest antivirus tools will use smart detection techniques, including heuristic analysis, and centralized control and monitoring.
Immutable systems
Immutable systems allow systems to be deployed easily from a validated image. This relies on strict version control...
