Advantage and disadvantage of computer security?

Answer 1

There are many advatages of Information security. You get protection of all information. financial transactions and other sensitive material is protected. The chances of fraud and theft are minimized.

Answer 2

advantages-can access your work from any computer on that network

allows you to share files, software and hardware

disadvantage's-

expensive to set up

expensive to keep running

if the server goes down then you can't access your work

Answer 3

1. Data Independence :
The data is held in such a way that changes to the structure of the database do not effect any of the programs used to access the data.

2. Consistency of Data :
Each item of data is held only once therefore no danger of item being updated on one system and not on another.

3. Control Over Redundancy :
In a non-database system, the same information may be held on several files. This wastes space and makes updating more time-consuming. A database system minimizes these effects.

4. Integrity of Data :
The DBMS provides users with the ability to specify constraints on data such as making a field entry essential or using a validation routine.

5. Greater Security of Data :
The DBMS can ensure only authorized users are allowed access to the data.

6.Centralized Control of Data :
The Database Administrator will control who has access to what and will structure the database with the needs of the

7.More Information Available to Users :
Users have access to a wider range of data that was previously held in seperate departments andsometimes on incompatible systems.

8. Increased Productivity :
The DBMS provides an easy to use query language that allows users to get immediate response from their queries rather than having to use a specialist "programmer" to write queries for them. whole department in mind


= Disadvantages of the Database Approach =

1. Larger Size :
More disk space is required and probably a larger and more powerful computer.

2. Greater Complexity :
For optimum use the database must be very carefully designed. If not done well, the new system may fail to satisfy anyone.

3. Greater Impact of System Failure :
"All eggs in one basket."

4. More Complex Recovery Procedures :
If a system failure occurs it is vital that no data is lost.

Hope it will help.

Answer 4

Advantages of dbms and draw back of file system. ->data redundancy and inconsistency. ->difficulty in accesing data. ->data isolation. ->Integrity problem. ->Atomicity problem. ->concurrent-access anomalies. ->security problems of file system. disadvantages of database. ->cost of hardware and sotware. ->cost of data conversing. ->cost of staff training. appointing to technical staff. ->database damage:in most of organisation,all data is intigrated into a single data base. if database is damaged due to electrical failure or database is courpted on storage media,then your data will be lost.

Answer 8

Network security is basically securing your network. Networks can be private, like a network within a company, or public. Securing the network involves preventing any misuse or unauthorized access of the network or its resources. For this, every user is given a unique user ID and password to access data pertaining to them. Without this authentication, no user is permitted to access the network. The network administrator oversees the operations of the network. Let us see some of the advantages and disadvantages of network security.

Advantages of Network Security

• Protect data
• Prevents cyber attack
• Levels of access
• Centrally controlled

Disadvantages of Network Security

• Costly set up
• Time consuming
• Requires skilled staff
• Careless admin
