14 © 2006 Cisco Systems, Inc. All rights reserved. SND v IPS Configuration Best Practices When setting up a large deployment of sensors, automatically update signature packs rather than manually upgrading every sensor. Place the signature packs on a dedicated FTP server within the management network. Stagger the time of day when the sensors check the FTP server for new signature packs. Group IPS sensors together under a few larger profiles.
15 © 2006 Cisco Systems, Inc. All rights reserved. SND v Accommodating Network Growth Network growth can occur by adding additional hosts or new networks. –Additional hosts added to protected networks are covered without adding new sensors. –Additional sensors can easily be deployed to protect the new networks. Some of the factors that influence the addition of sensors are as follows: –Exceeded traffic capacity –Performance capabilities of the sensor –Network implementation
16 © 2006 Cisco Systems, Inc. All rights reserved. SND v Scaling HIPS Systems Deploy a central management console to maintain a database of policies and system nodes. HIPS agents installed on similar systems should be grouped together. Ensure that you place common HIPS hosts into groups based on your security plan.
17 © 2006 Cisco Systems, Inc. All rights reserved. SND v Summary The Cisco IPS solution runs on network modules, purpose-built appliances, and routers, and it is implemented in software. The CSA solution consists of the CSA MC, the CSA software, and an administration workstation. The CSA intercepts operating system calls. It then determines if the call should be passed to the kernel for execution or if the suspicious nature of the call warrants an action. Use these factors to select the best Cisco IPS solution for your needs: –Network media –Intrusion detection analysis performance –Network environment –Number of sensors –Sensor placement –Management and monitoring options –External sensor communication IPS best practices support IPS policies. The key is to reduce the effort required to manage your sensors while maximizing their ability to defend your network.
