I have configure a RDP server to access my office data. And i did port forwarding in my CISCO ASA5505, and everything is working fine. Currently i like to setup it in such way that only pre-define public ip address can access my network, if some one tries from some other location ASA should reject the traffic. Basically i am try to filter my incoming traffic by Public IP ADDRESS

configure an access-list to allow only the known IP adress and applied it as &quot;in:&quot; to the interface facing internet/outside.

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
