Anti-virus program

An anti-virus program is software that detects and deletes computer
viruses. Anti-virus software can also prevent viruses from infecting your
computer in the first place.
The software can also check for computer viruses when you download files from the
Internet, receive emails and insert disks into your computer.

Digital Certificate
|
Digital certificates are the online equivalent of a passport or driver's licence.
They are used to authenticate a website or individual online. Digital certificates
are issued by a Certification Authority and contain the
name of the certificate holder, a unique certificate serial number, expiration dates,
and other information to verify the certificate's authenticity.

Encryption

Encryption is a process that ensures information is kept confidential and intact.
Encrypted information is 'scrambled' so it cannot be understood by anyone other
than the intended recipient.

A firewall is a program that helps protect your computer and its contents from outsiders
on the Internet. It stops unauthorised access to and from your computer.

Phishing
|
Phishing is a type of scam whereby fraudulent emails are randomly delivered and
are made to look like they are from a financial institution. These emails request
readers to reply or click on a link and provide their banking or credit card details.
They can look very authentic and link to a site that looks very similar to a legitimate
bank's website.

Security patches
|
Faults, errors and vulnerabilities are often found in computer programs and operating
systems after they have been released to the general public. Computer viruses often
take advantage of these 'security holes'. Software companies usually release security
patches that you can install onto your computer to fix these problems.

|
SSL
|
Secure Sockets Layer (SSL) provides confidentiality and integrity for Internet traffic
between your browser and a web server. You can tell if your Internet session is
secured with SSL when the web address you are visiting starts with "https://", and
you may also see a small padlock on the lower right hand corner of your browser.
If you click on this padlock you will be able to view the website's
Digital Certificate.

Trojan
|
In Greek mythology the Greeks offered a Trojan Horse as a gift to the city of Troy.
No sooner had it entered the gates when the Trojan Horse turned out to be filled
with soldiers who overtook the entire city! Today's Trojans also act by stealth.
These malicious computer viruses can be hidden within software, files or email attachments
that appear to be useful, but instead they compromise your security and can cause
a lot of damage. You can even unknowingly download a Trojan by simply visiting an
infected website.
Trojans spread when people are lured into opening a file, program, email attachment
or web link because they think it comes from a legitimate source. Trojans can also
be included in software that you download from the Internet. Never download software
from a source that you don't trust, and make sure your computer has up-to-date anti-virus
protection.

Viruses
|
Computer viruses are malicious programs that can cause damage to your computer and
information on your computer. They can also slow down the Internet, and use your
computer to spread themselves to your friends, family, coworkers, and the rest of
the Internet.
