Hi...my customer has an enquiry about implementing a IDS solution in his office. There is about 60 users in his office and they using 256K leased line to access internet and send/receive e-mail. Now they don't have firewall and they are using IP IOS in their 2651 router.
In this case, how can I propose a suitable IDS for them ??
What are the difference between they use IOS with FW/IDS and Cisco IDS Network Sensor ??
