This is a presentation about how system breaches can affect computer systems and data in business. This is part of my IT coursework*

2. How an organisation’s IT
systems can be breached
I.T systems need a variety of security features to prevent their systems
from being breached.
The easiest method of getting onto an organisation's network without
knowing any protection passwords is by using a Ethernet cable in the
site. This will enable the user accessing data that has been stored and
shared on the network. A security feature to prevent this is by using a
MAC filtering.
Emails in the organisation can be hacked easily by guessing a simple
password, or by asking general questions which may possibly be their
security question if they had forgotten their password.
Removable data devices can be used to steal data by transferring the
items or by physically stealing the organisations devices which has
backups stored onto.

3. Common security threats
These common threats are mostly internally done.
The main cause of this is untrained and unprofessional staff and
employees. This is mainly from them being un-protective and are being
lazy to look after data as the possible treats may not affect them or
aren't aware about them.
Another threat is malware, which can be affected with weak firewalls
and security protection software on the computer systems.

4. Potential impacts of security
threats
This may have impacts on the businesses profitability, as more money
will be required to spend to maintain and repair the I.T systems, data
and the networks . This will cause them a long-term effect as they will
need to take out loans in the future.
If another business has got records and data of the business, they can
used this a threat to compete with them by offering cheaper deals and
offers to the same audience and customers. This will ruin the businesses
reputation as existing and new customers will choose the other
business offering better and cheaper services.

5. Potential threats
This is when danger is found which can harm the system, which is
detected by the computer security.

6. Botnet attack
This is also known as Malware. It occurs when performing tasks on the
internet.
These happens without the user knowing by spreading from emails,
servers and fraud attacks.

7. Spam
This is an electronic virus which is hidden in fraud emails.
These are sent over through the internet by adverting fraud.

8. Adware
This is a software which automatically downloads in the background
advertising pop-ups when online, and popup is opened.

9. Trojan
This is a hacking program which is not self-replicating.
These attack on the operating system while performing on unsecure
webpages.

10. worm
This is a standalone malware which is on the computer that spreads to
others by the network and servers.

11. Spyware
This is a software which monitors and receives information from other
computers. These are installed by popups and without the user knowing
in the background.

12. Most common potential
threats
The most common potential threats are Worms, Trojans, Spam,
Spyware and Adware. Worms, and Trojans can harm the computer
system and network, whereas Spyware and Adware can save personal
information such as names, addresses, contact numbers and card
details. This can affect the user as this is used for fraud.
These threats are the easiest to get and cannot be detected by a non-
technical user, without any anti-virus protection software.
Anti- virus protection software detects threats and most of times
removes them. However sometimes the threats cannot or are not
removed with the software.

13. Impacts of potential threats
Worm: theses impact on the computer system and the internet network
by making everything slow. This happens by taking up a lot of space on
the hard drive which the operating system is on. Worms are can be
removed simply by installing a well known anti-virus software.
Spam: these impact on the computer system, by installing and storing
harmful software and files onto the hard drive. This is not detected by
anti-virus software and has to recognised manually.
Trojan: theses impact on the internet network by using your server to
gather personal details like worm, however more is affected by a Trojan
as they can be broken down into small things, such as proxy, FTP, DoS,
or remote access Trojans.

14. Spyware: these mainly affect the user as they try finding out personal
details such as credit cards, names, contact numbers and addresses.
This is then used as fraud or a scam.
Adware: these are very similar to Spyware, and mainly affects the user.
Adware normally finds out the user’s name, age, gender, email
addresses, passwords, pc configuration and users web history. From this
can find out more information and use this towards fraud and
scamming.

15. Legal responsibilities
It is the employer's responsibility to protect data in the organisation, by
relying and trusting their employees and staff.
Without putting the business at risk the employer would need to
employee trained and trustworthy staff.
However it is important that the employer ensures that the work
environment and his employees are safe and are following the health
and safety procedures.
For a business to success the employer will need to take responsibility
to lead the team.

16. Legislation to protect IT systems
and data (data protection act)
Computer systems and data can be protected by an act that was but
together by the government which is called the ‘Data Protection Act’.
This is mainly used by business, organisations and the government.
They secure their data by using computerised systems to ensure that
the data is kept safe and secure, without no transfers of anyone outside
of the UK without adequate protection.
There are also stronger legal protection to protect people in the
business for information such as ethnic, religion, criminal record, health,
sexual health and politic thoughts.
