computer security and critical data?

Background

computer-security for computer users must have

use various methods to computer security and

personal data, such as by installing anti-virus,

de-el-el. but sometimes it still feels less safe,

because then the rapid development of technology,

so that the hackers were slalu out viruses

terdahsyat and there is even one virus that sampe

now have not found the vaccine,

Guideline

makaning, we should be cautious with all slalu tricks

tricks of the hackers, and here are a few tips to

we prevented computer users and avoid hacking.


how to prevent / minimize them:

1. Beware of phishing sites in great many outstanding

current (example: www.swiiscash.net - should

formulation of an issue

>> Some of the things that make computer crime continues

occurs and tends to increase are as follows:

1. Increased computer and internet users
2. The number of software that was originally used to

audit of a system by looking for weaknesses

and gaps there might be misused to make

scanning system to others.
3. The number of software to conduct the probe and

infiltration are available on the Internet and can be

downloaded

free.
4. The increased capability of computers and Internet

users
5. Decentralization server so that more system

should be handled, while the limited human resources.
6. Lack of shoulder governing computer crime.
7. Increasing number of companies that connect

their LAN networks to the Internet.
8. Increased business applications that use the internet.
9. The number of software that has weaknesses (bugs).

Aim

>> There are several things that can answer the question why

we need to secure computer systems, among others:

1. Avoiding the risk of intrusion, we must ensure

that the system does not kemasukaan intruder who can read,

write and run programs that might interfere

or destroy our system.
2. Reduce the risk of threat, this is usually true in

institutions and private companies. There are several types

of intruders

that can attack our system.
3. Protect the system from the vulnerability, keretanan

will

make our system has the potential to provide access to

not allowed for others who are not eligible.
4. Protect the system from natural disturbances such as

lightning and

others.

View of the points above, is why we

need to keep your computer security is to keep

information, because information has become a commodity that

very important. Some even say that we have

are disebuah "Information based society". Ability to

access and provide information quickly and accurately

becomes very essential for an organization, whether a

form of commercial organizations (companies), universities,

government agencies, and individuals.


>> Aspects of computer security:
The core of computer security is to protect the computer and

network with the aim of securing the information that is

in it. Computer security itself includes some

aspects, among others:

1. Privacy, is something that is confidential

(private). The point is prevention of such information

not accessed by unauthorized people. Examples are

email or other files that should not be read someone else

even by the administrator. Prevention is possible

done is to use technology enksripsi, so

only the owner can find out information that the information

real.
2. Confidentiality, the data supplied to the

another for specific purposes but still maintained its

spread.

Examples of personal data such as: name, address,

no ktp, telephone and so on. Confidentiality will be seen

When asked to prove the crime a person, whether

holders will provide information to people infomasinya

who asked him or keep klientnya.
3. Integrity, the emphasis is not an information

be changed except by the owner of the information. Sometimes

data

who has not maintained its integrity terenskripsipun because

there is the possibility of encryption chpertext changed.

Example: Attack of Integrity as an email

sent the middle road and replaced it intercepted,

so that the email until ketujuan has changed.
4. Autentication, this will be done when the user login

by using the user name and password, if appropriate

or not, if the match will not be accepted and rejected. It

usually associated with access rights a person, whether he

The access is valid or not.
5. Availability, these aspects related to whether a

data available when needed / required. If a data

or information security is too tight will make it difficult

in data access. Besides the slow access

also inhibits Aspe terpenuhnya availability. Attack

often done on this aspect is the denial of service

(DoS), the discomfiture when the demand for services

data so that computers can not serve him. Another example

from denial of service this is to send requests

causing excessive computer can no longer

accommodate the load and eventually the computer down.


>> Some examples of activities that can be done to

computer security planning:

1. Calculate the losses if our information systems are

not

worked for 1 hour, for 1 day, 1 week and 1 month.

(Imagine detik.com server could not be accessed during

a few days. Every day she got a few million loss.
2. Calculate the losses if any error information (data)

the system information that we have. Examples of our WEB

announced the price of an item that is different from the

price

in our stores.
3. Calculate the losses if there is missing data, such as

how the loss suffered when the customer list and

invoices missing from our system and how much it costs

reconstruction again.
4. Does your company's good name is a thing

that must be protected? Imagine if a famous bank

with the security vulnerability of the data, going back and

forth

security incidents. Of cause many customers to move

to other banks for fear of security money.
