As Internet and web technologies are becoming more and more popular, so is the need to ensure security of data. Internet protocols and technologies are designed to be open in nature. Data travels freely over the Internet, seeking best possible route to reach its destination. Therefore, unless proper measures are adopted, data can be intercepted and altered by anybody accessing the Internet. While many organizations deploy firewalls and other access control mechanisms to improve security of data and transactions, these technologies have not proved to be sufficient.
To address security issues, Public Key Infrastructure (PKI) technologies have been developed in recent years. PKI is a system of digital certificates, data encryption and trusted third party certification and registration authorities. Until recently Public Key Infrastructure technologies were not available in the Middle East. Etisalat has filled up this gap by setting up a fully integrated Public Key Infrastructure in the Middle East. The UAE Cabinet of Ministers has recognized Etisalat as the Certification Authority (CA) for the United Arab Emirates.
