Security

The IPNC provides a number of measures for the protection of your data and systems against intrusion – either unintentional or malicious – from both the Internet and unauthorised dial-in users. These include:

–A Firewall.

–Encrypted Passwords.

–CLI.

–Time Profiles.

–NAT / Proxy Server.

In essence, a firewall creates a barrier between your subnet and the outside world, and controls who leaves and who enters, according to one or all of several criteria. Anyone who fails the test is prevented from entering or leaving, i.e., starting a session with an internal or external application. The main criteria can be defined as:

1.All common TCP/IP protocols can be restricted to incoming or outgoing only. This means that, for example, your network administrator alone could be permitted to use diagnostic and management protocols, and further restrict his use of them to incoming access only.

2.Access to and from services with specific IP addresses and masks can be prevented.

3.Filters can be defined to search for specific data patterns. Traffic containing a match can then be allowed through the firewall or not, as required.

The systems security features can be combined for maximum protection. For example, the network administrator’s restrictions can include a time profile, limiting access to outside normal working hours, and a user profile set up to check that the CLI of the incoming call matches the number of his home or mobile phone. This gives full coverage for an out-of-hours emergency with maximum protection in normal circumstances.

For Internet services, the system includes a proxy server providing NAT / IP masquerading to conceal your local addresses from other Internet users. Password protection, with optional password encryption, is available for all services, including dial-in services.

The importance of security cannot be over-emphasised and the part users play cannot be under-estimated. Just as you take care of your credit cards, you must be mindful of security issues. No matter how powerful a password verification technique is, it is no use if the password is written on a note stuck to your PC. Your system’s security is ultimately your own responsibility. You must:

–Store back-ups and all system information securely, for both security and disaster recovery purposes

–Change all passwords regularly

–Change the default start IP address of your system

–Install a reliable virus protection program and keep it up to date

–Ensure that all members of your staff are aware of security issues.

We recommend that you utilise your default firewall by naming it and including it's user and service profiles where appropriate. Punch additional holes in the firewall only as and when experience shows they are needed.
