> *Intrusion Detection Systems (IDS)***
>
> Another element to securing networks is an intrusion detection system (IDS).
> IDS is used in
>
> complement to firewalls. An IDS works in conjunction with routers and
> firewalls by monitoring
>
> network usage anomalies. It protects a company's information systems
> resources from external aswell as internal misuse.
>
>
>
> • Signature-based: These IDS systems protect against detected intrusion
> patterns. The
>
> intrusive patterns they can identify are stored in the form of signatures.
>
> • Statistical-based: These systems need a comprehensive definition of the
> known and
>
> expected behaviour of systems.
>
> • Neural networks: An IDS with this feature monitors the general patterns of
> activity and
>
> traffic on the network and creates a database.

> *Web Server Logs***
>
> System and network logs can alert the Web administrator that a suspicious
>
> event has occurred and requires further investigation. Web server software
> can provide additional
>
> log data relevant to Web-specific events. If the Web administrator does not
> take advantage of these capabilities, Web-relevant log data may not be
> visible or may require a significant effort to access.

> Identification of an individual through unique physical characteristics is

> *Cryptography***
>
> In literal terms, cryptography means science of coded writing. It is a
> security safeguard to render

>
> information is to be used, it can be decoded. "The conversion of data into a
> secret code for the
>
> secure transmission over a public network is called cryptography.
