Online Security
Our experts suggest a system of hardware,
software and procedures that offers protection for consumers and organisations
by providing a safe environment for conducting business via the Internet.
ZeenNet aims to reduce the risks of cyber crime, computer viruses, interception
of information and hackers who exploit your Internet connection and website.
Major online security threats include:
Viruses - Malicious pieces of computer
code that make unauthorised changes to a computer. A virus can be transmitted as
an attachment on an e-mail or by downloading infected programming from other
websites
Hacking - An attempt by an intruder to
gain unauthorised access to computer systems. A ‘hacker’ is a person who
attempts to gain unauthorised access to a computer system for fraudulent
purposes.
Secure access (password authentication) -
A username and password is assigned to each user to allow access to a website
Used: when a low security level is required
Secure connections - Secure Sockets Layer
(SSL) combines a basic password system with protocols that encrypt data
transmissions. Used: for websites that sell products and services
Secure interconnection - Public Key
Infrastructure (PKI) uses keys to scramble and decipher messages. Used: for high
value business, government and military transactions
Secure personal connection - Pretty Good
Privacy (PGP) uses public key encryption. Used: as a popular security option for
individuals
Secure networking - Virtual Private
Networks offer one of the highest levels of security using advanced encryption
and tunnelling technologies. Used: by organisations with multiple office
locations
E-Mail security - Where similar software
is used to send and receive encrypted e-mail messages so only the intended
recipient can read it. E-Mail software includes:
Dedicated e-mail encryption - Uses same
technology as PKI and PGP and is available as a plug-in to existing e-mail
software (e.g. Microsoft Outlook, Eudora)
Secure e-mail gateways - For businesses
that do not require e-mail security within their own office environment yet do
outside the internal mail gateway
Anti-virus software - Installed on a
computer to protect and eliminate incoming viruses
Firewall - A firewall is software that
separates an organisation’s public Web server from its internal network and
provides the first layer of security for your computer when you connect to the
Internet
