New Branch Office - High Security

Question

Hello
we plan to have 5 branch offices each with around 40 users. All branches will be in different geographical locations. Best Security needs to be implemented in all branches. All services email, SAP, Portals are hosted in the HeadOffice Datacenter. Each Branch will have dedicated internet 5MB for Voice and DATA
Guidelines for security  -
ensure users cannot insert usb or cd on laptops /desktops
laptops/desktops are allowed to access restrictive internet from Office
Outside Laptops / Tablets not allowed to connect to network but allowed internet via wireless using Guest
to access internet from home or Cafe users needs to connect to office VPN and then access from local Internet server (Proxy)
vendors proposed following ;-
3921 router for branch
ASA 5510 for branch
3945 router for HeadOffice ( VPN )
Filtering - Web Washer - Mcafee
Experts can advice what hardware will best fit on branches, what other devices I need to achieve the above goals
Thanks

Answer 1

Hello Vishal,
I would recommend the following:
For Branches:
1-  Cisco : 2921 : Voice Licensed (you dont need a higher end above this series for 40 users).
2-  Cisco ASA 5510: (This will be your Security appliance at each branch).
For Head Quarter:
1-  Cisco ASA 5520: (This Will be Your HQ Security Appliance).
2-  Cisco 3925 or 3945 router (Voice Licensed).
For Your Security Guidelines, here is my answers:
ensure users cannot insert usb or cd on laptops /desktops
FOr this purpose, you Can disable the administrative privelege on the Notebooks and PCs for All users and remove the software driver for thier USPs.
laptops/desktops are allowed to access restrictive internet from Office
FOr this Purpose, I would recommend using Cisco IronPort WebFiltering, it Can be easily Integrated with your Active Directory and Enforces all Filtering Policy you would require.
Outside Laptops / Tablets not allowed to connect to network but allowed internet via wireless using Guest
For this Purpose, I would recommend deploying Wireless LAN Controller at your HQ to have benefit and full advantage of managing your Wireless Infrastructure.
to access internet from home or Cafe users needs to connect to office VPN and then access from local Internet server (Proxy)
FOr this Purpose , I would also say Your Best Option is to have Remote Access VPN & (VPN Client) deployed at all employee's Notebook. Though, You Can have another Option which to have SSL-VPN deployed at your HQ, but this will have additional cost as its added value featured licensed per number of users.
Let me Know if this answers your Question Or if you require additional assistance.
