Corporate portal as security backbone

Network topologies found in audits and reviews are not capable to fulfill the needs of security and flexibility. Specialized networks and protection systems increase the complexity and reduce the overall security. Central corporate portals can be used as IT-security backbones. Constructing the corporate portals with reverse-proxy technology and with internal firewalls will secure, that no connection to sensible data or central systems will be possible without the central control. Not only the IT-security will benefit, but also the flexibility increases and the costs for operating and support will decrease. The author will present a praxis-relevant approach and some ideas about the migration.
