Data security on networks

Nowadays, with the wide use of computers, users always come across data security issues. So we will give a brief introduction to the possible existing flaws which are likely to pose risk to data security on network.

The drawbacks of TCP/IP
Since the mainstream protocol on network in use, TCP/IP is defective in data safety when technicians laid great emphasis on development and convenience. As a result, numerous protocols on network have severe bugs which will increase the risk of data safety damage. What's worse, some bugs may attack target system directly.

The defective structure of network
Since internet is composed of numerous local area networks, the data needing to be delivered will be passed on via multiple machines. At this time, there is a chance that the data in delivery can be robbed.

Flaws of operating system
Due to the drawbacks in logical design or errors in the process of programming, there exist flaws in operating system. Malicious users are likely to launch virus attacks on operating system thereby stealing the data in it and even damage the operating system.

Lack of data security awareness
Currently, numerous users are utilizing networks blindly since they have little knowledge of network. Frequently, users get stuck in network traps via logging in malicious websites, which will alter the registry table of PC, and even infect other websites.

After introducing the flaws of network, users are supposed to know something about the current threats to network so as to protect data.

Trojan horse
As a malicious procedure, Trojan horse is always in the disguise of game programs or tools thereby slipping in the target computer and acquiring access and charging permission when users connecting their computers to network.

Trick of www
Since users can take the advantage of IE explorer to visit various websites, malicious users are likely to copy all images of www. What's worse, after that, those users may put the images into the target server thereby monitoring activities of other users which will generate privacy leakage and data safety damage.

Effective data security management measures on networks to protect data

Enhance data safety of user accounts
Since system login accounts and online bank accounts are all involved in user accounts, users are likely to suffer severe losses if those data get lost. To maintain data safe, users are supposed to set password for default administrator account, and the password might as well consist of numbers, letters and special marks. What's more, it is not advisable to set similar usernames and passwords and users had better alter them regularly.

Intrusion Detection Technology
Being designed to maintain data safe for system, Intrusion Detection Technology can supply timely detection of malicious internal or external attacks.

Firewall Technology
Serving as the door between internal network and external network, firewall technology will be utilized to prevent internal network from being attacked. More importantly, attackers can not control the access permissions of other information via altering data security strategies.

Data Encryption Technology
Users can encode their data with data encryption technique according to a certain algorithm, which can be used to insure vital data safety, so those data will be hidden thereby avoiding privacy leakage. However, if users would like to use those data, they can decrypt those data according to the corresponding algorithm.
