CCTV and Security

Not an issue that denotes a passive response from the general public, CCTV surveillance is more of a debate than a topic. Likened to the idea of Big Brother due to the amount of closed circuit television cameras there are in the UK alone (approximately one for every 14 people), many members of the public feel their privacy is violated by the little eyes in the sky.

It's said the average person is reportedly spotted on camera approximately 300 times a day, but out of those three hundred moments how many times do you realistically notice? Or even care? Well even if you don't notice, this safety measure seems to provoke outrage within some people.

This is where the debate lies.

It falls into three categories: a) the privacy issue, b) their effectiveness, and b) do they lower crime?

People's privacy is a sensitive subject and as such, should be treated with a certain amount of care. Why would you want your every move to be filmed? Does your every move need to be filmed? From buying your groceries to catching the train to work you are watched 24/7. A reason behind privacy being an issue could be based on the sheer amount of cameras that you see. It spooks people and creates the idea that you might be in a dangerous area. However as the concept of CCTV becomes more widespread hopefully the public will be more accepting and realise eventually it will make for a safer environment.

The UK has the highest amount of CCTV cameras than anywhere else in the world.

Have they proven to lower crime? No. Does this mean we don't need them? Absolutely not! Whichever side of the fence you sit on, it's hard to argue that the use of CCTV is useless. Need we remind you of the crazy lady who threw the innocent cat in the bin? We rest our case. More seriously, there are more and more reports that CCTV is helping the police forces solve crimes; surely a surveillance presence is better than no presence at all?

They may not fight crimes but they'll sure as hell try to solve them. Moreover they act as a deterrent. Like any other security presence, CCTV surveillance acts as a deterrent and a preventative.

Place of vulnerability and threat in an assessment of the risks to the security of information

A risk assessment is the key organising an Information Security Management System (ISMS). The central elements of a risk assessment are: assets, vulnerabilities, threats, impact, probability and risk. The following definitions will clearly be place of vulnerability and threat in an assessment of the risks:

?

• An information asset can be any piece of information which has value to an organization. Assets may take any form, not necessarily electronic.Telephone directory of internal paper, in the mind of someone an audio recording of a presentation, or even a brilliant idea is perhaps an asset! each asset shall be entered in a register active and assigned at least an approximate value.

• A vulnerability is a weakness in an asset which leaves open the potential damage event indésirable.Vulnérabilités could include elements such as: loss of the hard disk is stored on (for electronic data), or o

  f flammable (for paper documents).

• A threat is a potential adverse effects which may exploit a vulnerability to damage or destroy an asset information.Threats can be very varied, from catastrophic (e.g. direct Meteor strike, the Bank business bankruptcy) much smaller scale (e.g. E-mail server crash, lock failure): this type is most likely.

• Impact is the effect that a threat on the fleet organization may or may not be related to the severity of the threat. For example, it can be a serious lack of staff coffee machine threat if the electrical circuit develops a fault. However, given that it has no effect on the company, the impact is considered low.

• A probability is the probability that materialise a threat.Probabilities can vary greatly, from extremely small (e.g. a Meteor strike) to very high (e.g., a server crash).

• A risk is the confluence of all the above items.The risks are cataloged in a risk register and are assigned priorities according to a risk matrix.This form of the output of the risk assessment.

?

The concepts of vulnerability and threat can be considered as complementary to an assessment risques.Un asset which has no vulnerabilities have any risk, however serious threats apply to elle.à Conversely, an asset that is not exposed to any threat even not will be subject to any risk, but it has many vulnérabilités.Malheureusement none of these two situations is likely to be found in real life.

?

The roles of vulnerability and threat in an evaluation risk are essential for the financial year when terms information security risks, it may not immediately obvious that the vulnerabilities and threats are in fact, since the information is less tangible asset type, for example, equipment industriels.Cependant, it is important to estimate accurately, because the outcome of the risk assessment determines the entire Information Security Management System (ISMS) thus TargetObject, vulnerability and threat are essential to executing any form of risk assessment concepts.
