Configuring IPsec

Before you configure IPsec, you need to:

• Install IP Security (IPsec) software (see “Installing IP Security (IPsec)

Software” on page 2-11).

• Secure your site.

• Secure your configuration.

• Select an encryption strength.

• Use the Technician Interface secure shell to enter a node protection key

(NPK), and then enter the same NPK in Site Manager.

Site Security

To enforce IPsec, carefully restrict unauthorized access to the routers that encrypt

data and the workstations that you use to configure IPsec. Keep in mind that the

DES and MD5 encryption standards that IPsec uses are public. Your data is secure

only if you properly protect the encryption keys. The configuration files that

contain these keys include safeguards to prevent unauthorized access.

Configuration Security

Store any files containing encryption keys on diskettes (or other removable

media), and keep the media in a secure place. Physically protecting your

equipment is always a good strategy and the easiest way to prevent unauthorized

access to these files.
