Unit 11 - Physical Security

Physical security measures include which of the following?

• Site Security Locks

• CCTV

• Cloud Backups

• Firewalls

• Anti-virus software

When data is stored in a different location and connected via the internet

• Cloud Backups

• On-Site Backups

• Off-Site Backups

• Protected Cabling

When data is stored in the same building as the original data.

• Cloud Backups

• On-Site Backups

• Off-Site Backups

• Biometrics

Fingerprint scanner or facial recognition.

• Biometrics

• CCTV

• Protected Cabling

• Card Entry

Advantage of Incremental Backup?

• Quicker and requires less storage space than a full backup

• Requires huge amounts of data storage capacity

• Normally run manually by IT staff

• Easy to recover the data even if the network is down

Why is it important to back up data?

• Without a backup, many businesses will fail if they suffer a major data loss

• If a business is using a central server they need to fill up the available memory capacity with as much data as possible

• So that it is harder for hackers to access their data

• To check that security measures in place are functioning correctly

What is protected cabling?

• When a cable is wrapped in extra layers, rather than just rubber.

• When old cables are replaced by thicker cables

• When cables are replaced by wireless technology

• When RFID devices are installed so that stolen cables can be traced

Three main types of backup.

• Full Backup

• Incremental Backup

• Differential Backup

• Partial Backup

• Incomplete Backup

Difficult to tamper with and provide clear visual evidence of who has been in a room.

• CCTV

• Biometrics

• Security staff

• Site Security Locks

Disadvantage of on-site backups?

• Data could be destroyed by whatever damaged the original data.

• Data can be accessed by hackers via the internet

• Slow to retrieve that backed-up data

• Can't access the data if the internet is down.
