The importance of effective network security strategies

In more recent years, security needs have intensified. Data communications and e-commerce are reshaping business practices and introducing new threats to corporate activity. National defence is also vulnerable as national infrastructure systems, for example transport and energy distribution, could be the target of terrorists or, in times of war, enemy nation states.

On a less dramatic note, reasons why organisations need to devise effective network security strategies include the following:

  • Security breaches can be very expensive in terms of business disruption and the financial losses that may result.
  • Increasing volumes of sensitive information are transferred across the internet or intranets connected to it.
  • Networks that make use of internet links are becoming more popular because they are cheaper than dedicated leased lines. This, however, involves different users sharing internet links to transport their data.
  • Directors of business organisations are increasingly required to provide effective information security.

For an organisation to achieve the level of security that is appropriate and at a cost that is acceptable, it must carry out a detailed risk assessment to determine the nature and extent of existing and potential threats. Countermeasures to the perceived threats must balance the degree of security to be achieved with their acceptability to system users and the value of the data systems to be protected.
