How can we Strengthen Databases to Protect the Security of Information?


Databases must be strengthened to protect the security of data, because the databases save the vital data relating to any business. EtechNg best website designers in nigeria is providing this info 

·  User Access Control of Database
·  Database User Discrimination and Authentication
·  Separation and Control of Database User Permission
·  Database Network Security
·  Database Security Audit

User Access Control of Database
The rights for users to access a database should be controlled based on user levels.

User access control involves the following aspects:

Ownership of Application Software
The owner of application software has full control access to the software. It is not recommended to grant an account with full control access of the software it owns.
Hybrid Media Works Graphic Designer in Islamabad is providing database controlled security to valued clients.

Database Management Permission
With the database management permission, users can change storage and configuration permissions of the database. Therefore the management permission of users must be defined clearly. If a user only has to store data to a database, the user only needs storage permission.

Access to Files and Folders
Users are given the read permission, write permission and execute permission of files and access permission of folders.



Owner of database Service or Daemon
The owner of the database server or daemon must have a designated account.

Public Permission of the System Directory Table
The system directory table contains much useful information for database. To prevent unauthorized users from accessing a database, only public information can be reserved in the system directory table. Important information of the database must be stored in other places of the OS.

Database User Discrimination and Authentication
Discrimination and authentication ensures that only authorized users can access the database.

User Account Authorization
If any account in the OS is authorized to access database, the security of the database may be under threat. Therefore only the users having the permission can access database.

Database Administrator (DBA) Permission
The DBA permission is of high level in a database. If this permission is not restricted, the security of a database may be under threat. Therefore the DB administrator permission must be assigned strictly.

Database Access Permission
To prevent unauthorized users from accessing database, the permission of accessing database must be set strictly.

How to Troubleshoot Complex IP Network ?



Over the last decade, the Internet has changed drastically. The key point, which remained constant over the years, is that all the measures describing the network technology are related to the OSI model. Even if the new technology does not correspond to the OSI model accurately, all the technologies are layered .Divide and conquer is the rule to win over faults.EtechNG web design experts in abuja describes common Troubleshooting Protocol of IP Network which are bearing services for clouds and huge servers, data centers.

Layering Principle in Troubleshooting
Over the last decade, the Internet has changed drastically. The key point, which remained constant over the years, is that all the measures describing the network technology are related to the OSI model. Even if the new technology does not correspond to the OSI model accurately, all the technologies are layered. The layering analysis of the network fault is, therefore, very important.

The layering principle is very simple and is based on the logic that the upper structure can work normally only when the lower structure is normal.
Therefore, before addressing the fault in the upper structure, ensure that all the lower structures work normally.
For example, in a frame relay (FR) network, the FR connection fluctuates due to the unreliable nature of the physical layer.
Apparently, the route that reaches the remote end is interrupted. If the maintenance engineer concludes that the fault in the routing protocol occurs due to the phenomenon on the surface, the fault cannot be located and corrected promptly and accurately. HybridMediaWorks Graphic Designer in Rawalpindi suggests to get detailed layered troubleshooting technique of IP network, following link is designed for you.

What is Link Capacity Adjustment Scheme ( LCAS ) technology?

With the diverse and complex development of the services transmitted in the Transmission network, the demands for various access bandwidths have increased. As a result, the earlier monotone bandwidths (such as a VC-4) do not meet the requirement. This has led to the emergence of the concatenation technology. Concatenation is classified into adjacent concatenation and virtual concatenation. As per information provided by HybridmediaWorks Web Development Company Rawalpindi The virtual concatenation is more flexible than the adjacent concatenation. The virtual concatenation also has a higher bandwidth utilization. The problems in both the adjacent concatenation and virtual concatenation are as follows:

·  When any physical channel fails, all the concatenated channels fail and all the services are interrupted.
·  After services are set up, if you adjust the bandwidth of the services, the services are affected to a great extent.
The link capacity adjustment scheme (LCAS) technology provides a solution to the preceding problems. LCAS improves and complements the virtual concatenation technology. LCAS dynamically adjusts the number of virtual containers required for service mapping to meet the bandwidth requirements of various services. Through LCAS, the bandwidth utilization increases and the robustness of virtual concatenation is enhanced.



NOTE:

LCAS is applicable to only the virtually concatenated channels.
The advantages of adopting the LCAS function on the network are as follows:

·  LCAS dynamically adjusts (adds or deletes) the service bandwidth without affecting the availability of the existing services.
·  When some of the physical channels in a virtual concatenation group fail, LCAS helps to shield the failed channels and the other physical channels continue to transmit the services normally. This prevents the services from being interrupted when some of the physical channels fail. After the failed physical channels are restored, they can transmit services again.Thanks to the information provided by HybridMediaWorks Website Designer in Islamabad

LCAS complies with the following standards:
·  ITU-T G.806
·  ITU-T G.7042/Y.1305 (2005)

What JavaScript (JS) is? And What JS isn’t?




JavaScript or simply known as JS is the programming language that make interactivity along with custom behavior in action to our sites. It is a scripting language which falls in client-side. That means it is executed on the user’s machine platform instead of server side. There are other web programming languages like Ruby and PHP. We can safely say JavaScript is dependent on the browser’s setting and abilities. As per Hybridmediaworks Graphic Designer in Islamabad JS depends on the user and the machines on which browsers are running. The user can chose to turn it off or the device sometimes doesn’t support JS. Other names of JavaScript are dynamic and loosely typed programming language.

What JS isn’t?  

JavaScript the name is nice-looking but quite confusing. Although name is Script , JavaScript which has nothing to do with Java interestingly.JS was created by Brendan Eich at Netscape in 1995 and at that time it was basically named “LiveScript.” But with the passage of time and technically more involvement along with other languages Java was added instead of Live in the name.





 JavaScript JS has some sort of bad repute due to unwanted redirects, loathsome pop-up windows like security vulnerabilities are few names.
ikonicSolution Software House in Islamabad says this is because of the modern era development in which modern browsers have mostly trapped on to the darker part of JavaScript development and locked it down. Which means it’s up to us to use the control JavaScript has given, in a responsible way.
