- Phishing
- A type threat which attempts to gain access to passwords,
financial details and other such priviled information. Often this

- Accidental Damage
- May be caused by a natural disaster
(flooding), mischief or accidental
mishap, and can result in losing of a
computer's data.

- Possible consequences
of an attack....
- Reputation for being secure
might be damaged, potential
customers put off costing the
business money.
- When an organisation's secrets are
spread to competitors or to the wider
public, any particular advantage the
organisation has will be lost.
- Identity theft could cause
problems with obtaining loans and
other contractual agreement.

- Physical Barrier
- These include turning off computers and
locking offices when the systems are
unattended ton prevent damage by people,
the environment (for example: fire, flooding)
or theft.

- Access Levels
- These can be set up the allow individuals to
have access to only specific levels of an
applications and to prevent unauthorized

- Anti-virus Software
- This is set up to intercept computer viruses
before they can become resident on the
computer. The software can isolate the
virus, remove it and sometimes repair any
damage.

- Encryption
- This is used to codify data so that it cannot be
read by anyone who does not have the key to
the code. An algorithm, sometimes known as a
cipher, is applied to the data at the transmission
end and the reverse is applied at the reception
end

- Backup and recovery
- Making a backup of data is the only way
of recovering from a total data disaster.
Many individuals and organizations
backup data to Flash solid state storage
devices or magnetic tape at night. The
tapes are stored safely in a separate
place, so that they are not destroyed by
any disaster, which could destroy the
master system (for example: fire,
earthquake).

- Different types of
backups
- Full System Backup of all data held for a
specific purpose.
- Incremental Backup of files or data that as been
changed since the last full backup and its faster
than running a full backup every time.
- Backups to removable media, such as a
removable hard drive, USB sticks, CD's and
DVD's.

specific purpose.
- Identity Theft
- When someone steals your personal
details in order to use them to open
bank accounts and get credit cards,
