The employee is responsible to ensure the family member does not violate any policies, does not perform illegal activities, and does not use the access for outside business interests. The employee bears responsibility for the consequences should the access be misused. 3. Please review the following policies for details of protecting information when accessing the corporate network via remote access methods, and acceptable use of ‘s network: a.

Acceptable Encryption Policy b. Virtual Private Network (VPN) Policy c. Wireless Communications Policy d. Acceptable Use Policy 4. For additional information regarding remote access connection options, including how to order or disconnect service, cost comparisons, troubleshooting, etc. , go to the Remote Access Services website. 3. 2 Requirements 1. Secure remote access must be strictly controlled. Control will be enforced via one-time password authentication or public/private keys with strong pass-phrases.

For information on creating a strong pass-phrase see the Password Policy. 2. At no time should any employee provide their login or email password to anyone, not even family members. 3. employees and contractors with remote access privileges must ensure that their -owned or personal computer or workstation, which is remotely connected to ‘s corporate network, is not connected to any other network at the same time, with the exception of personal networks that are under the complete control of the user. 4. mployees and contractors with remote access privileges to ‘s corporate network must not use non- email accounts(i. e. , Hotmail, Yahoo, AOL), or other external resources to conduct business, thereby ensuring that official business is never confused with personal business. 5. Routers for dedicated ISDN lines configured for access to the network must meet minimum authentication requirements of CHAP. 6. Reconfiguration of a home user’s equipment for the purpose of split-tunneling or dual homing is not permitted at any time. 7.

Frame Relay must meet minimum authentication requirements of DLCI standards. 8. Non-standard hardware configurations must be approved by Remote Access Services, and InfoSec must approve security configurations for access to hardware. 9. All hosts that are connected to internal networks via remote access technologies must use the most up-to-date anti-virus software (place url to corporate software site here), this includes personal computers. Third party connections must comply with requirements as stated in the Third Party Agreement. 0.

Cable companies such as AT&T Broadband provide Internet access over Cable TV coaxial cable. A cable modem accepts this coaxial cable and can receive data from the Internet at over 1. 5 Mbps. Cable is currently available only in certain communities. CHAP. Challenge Handshake Authentication Protocol is an authentication method that uses a one-way hashing function. DLCI Data Link Connection Identifier ( DLCI) is a unique number assigned to a Permanent Virtual Circuit (PVC) end point in a frame relay network.

DLCI identifies a particular PVC endpoint within a user’s access channel in a frame relay network, and has local significance only to that channel. Dial-in Modem . A peripheral device that connects computers to each other for sending communications via the telephone lines. The modem modulates the digital data of computers into analog signals to send over the telephone lines, then demodulates back into digital signals to be read by the computer on the other end; thus the name “modem” for modulator/demodulator. Dual Homing.

Having concurrent connectivity to more than one network from a computer or network device. Examples include: Being logged into the Corporate network via a local Ethernet connection, and dialing into AOL or other Internet service provider (ISP). Being on a – provided Remote Access home network, and connecting to another network, such as a spouse’s remote access. Configuring an ISDN router to dial into and an ISP, depending on packet destination. DSL Digital. Subscriber Line (DSL) is a form of high-speed Internet access competing with cable modems.

DSL works over standard phone lines and supports data speeds of over 2 Mbps downstream (to the user) and slower speeds upstream (to the Internet). Frame Relay. A method of communication that incrementally can go from the speed of an ISDN to the speed of a T1 line. Frame Relay has a flat-rate billing charge instead of a per time usage. Frame Relay connects via the telephone company’s network. ISDN. There are two flavors of Integrated Services Digital Network or ISDN: BRI and PRI. BRI is used for home office/remote access.

BRI has two “Bearer” channels at 64kbit (aggregate 128kb) and 1 D channel for signaling info. Remote Access. Any access to ‘s corporate network through a non- controlled network, device, or medium. Split-tunneling. Simultaneous direct access to a non- network (such as the Internet, or a home network) from a remote device (PC, PDA, WAP phone, etc. ) while connected into ‘s corporate network via a VPN tunnel. VPN Virtual Private Network (VPN) is a method for accessing a remote network via “tunneling” through the Internet.
