To ensure greater safety for network operations, various security measures have been implemented. These include basic countermeasures against external attacks, such as firewalls and anti-virus software. Sensitive information transmitted across networks is protected from interception by data encryption.
Network authentication refers to measures that prevent illegal network access from any point including those via wireless-LAN facilities, not just points outside the network. Confidential data such as personal information and corporate business information must be strictly controlled, a requirement that means blocking network access by assumed identities - individuals pretending to be authorized users. For this reason, trends in recent years have moved toward difficult-to-forge IC cards combined with personal identification such as IDs or passwords, as well as biometrics or bio-authentication techniques such as fingerprints. These personal authentication techniques allow management of entry/egress to and from offices and securing of desks and lockers, not just access to computers or networks. In turn, this makes it possible to establish a more comprehensive security strategy.
The measures available to counter threats to network or information security are diverse and multifaceted.
The optimal security solutions for a certain company must combine the various tools necessary to meet
the specific needs of that company. Security measures can entail significant cost, and no measures can
ensure 100% safety. But given the current cry for corporate social responsibility in such matters, there
can be no doubt that the importance of security measures will continue to grow. |
