Significant Actions to Take Care of Cables Accessories

For any cable to be worked as detect free & to operate without any problem, there are few things we need to work on:

Wrap your cables appropriately:
Most of the cable defects occurred due to ignorance of cables wrong wrapping. Sometimes the situation goes more worse when we become too lazy to wrap them appropriately. Whenever we people forgot to wrap a cable carefully, we further invite cables breakdown and damages.

Make sure the cables we used are insulated: It is the one major thing we need to do while we buy cable accessories online. Make sure the cables are insulated not from damage purpose only but for safety purpose also. If you use a cable which is wrongly insulated or naked then you are inviting more damages. So, make sure that the cables are correctly insulated. If you can’t do it by yourself then take help from technician who is expert in doing this.

Place your cables appropriately: We need to place out cable accessories perfectly at our workplace and at our home as well.So, that there will be lesser chances of damage over there.

Keep it away from water: Water is good solvent so whenever the comes in contact of electricity then it passes current. Which can be harmful for anybody. So, make sure you keep the cables away from the reach of children.

RAID Controllers and It’s Types

Raid controller Stands for redundant array of independent disks Controller. It is an independent device which is used to manage multiple hard disk drives (HDDs) or solid-state drives in your personal computer.

Different types of raid controllers that offer different functionality and benefits.

Types of Raid controllers:

Raid 0: Raid 0 Offers a good speed but not offer idleness. It uses disk striping to spread out the data between two and will not protect the data in case of hard drive failure and the data will be lost.

Raid1: Raid 1 offers a good redundancy but not providing a very good speed as like Raid 0. It will then follow a process named disk mirroring for data storage. This requires minimum two drives. All the information will save in both the drives at the same time. The RAID system will protect all the data and will confirm no data loss in case one of the drives failure cause.

RAID 5: Raid 5 is a type of controller which gives an outstanding stability between speed and redundancy. It uses the disk striping method with uniformity. In this raid the PC needs minimum three hard drives. In this data will be stripped in between the hard drive, which will further enable the reconstruction if the drive failure case arises.

RAID 6: It offers a great increase in reliability. It employs the parity strips already there to protect the data whenever the hard drive failure occurs. It is mainly used in SATA Drives. And you can Buy ATA Raid Controller Cards Online according to your requirements.

Top Mobile Security Best Practices for Developers | Desnav.com

The security of an application that you are developing is a bare necessity. Even a single breach in the application can cause create havoc for your work and create a bad name for you as a developer. Security of the application should be the topmost priority for any developer since the starting of the first line of code.

Write a secure code

If your code is vulnerable and has bugs, then many attackers will be easily be able to enter into an application stealthily. A hacker can reverse engineer the code and tamper with it, they will need a public copy of your application to do the same. Studies and researches have shown that malicious code is affecting over 11.6 million of mobile devices everywhere.

Minify and obfuscate your code so that it cannot be reversed engineered. Run your application through tests time and again to fix the bugs once they are exposed to you. Design your code yourself so that it is easy to adjust and patch. Also, use code signing and code hardening.

Encrypt all data

The entire data, even thing that is exchanged over your application must be encrypted. For those who do not know about the term encryption, basically it is just the scrambling of the plain text that converts a word into a vague alphabet soup that does not hold any meaning for anybody else except for the one who have the key.

Be extra cautious with the libraries

When you are using the third-party applications then you must be careful about the code that you are using for the application. Some libraries are extremely insecure for the working of the application.

Use only the authorized API’s

API’s that are loosely coded can grant a hacker privileges that can be used mischievously. For example; if you cache the authorization information then it will easily help the programmers to use the information for making all the API calls. It will also the make the life of the coders easier by making the easy use of the APIs. However, it gives them a loophole through which they can Hijack the privileges.

Use the authentication of a really high level

Some of the biggest security breaches have occurred due to the weak authentication factor. You would not want it to ruin everything for you. Authentication means personal identifiers and the passwords that will act as the barrier for the entry. This depends upon the users of the application and even the developers must educate the users about the importance of the high-level authentication.

If you are a developer then you must design your application as such that it does must not accept any password except for a strong alphanumeric password. A password that you set must be renewed after three or six months. With time the multi-factor authentication has gained prominence as it not so easy to crack. It works on two factor authentication; it requires static password and a dynamic OTP.

If the application is too sensitive then bio-metric authentication which includes fingerprints and retina scanning must be used.

Use the temper detection technologies

These techniques are used to set off the alarms in case if someone tries to tamper the code or wants to inject any malicious code. With active temper detention you can make sure that the code will not be functional if it is once modified.

Make proper sessions for handling

The sessions on your mobile phone must last longer than the desktops. It will make the handling session harder for the server. Prefer using the tokens instead of the device identifiers when you are identifying a session. Tokens can be easily revoked at any time which will make them a more secure when you talk about the stolen devices. Enable the remote wiping of the stolen device and the remote log-off.

Do the tests repeatedly

The process of testing the security apps is unending. New threats emerge every now and then and for the digitally derived world quick solutions are needed. You must invest in threat modelling, penetration testing and make use of the emulators to know and understand the vulnerabilities of an application. Fix all the bugs and patch the issues that come along with it.

Use the best cryptography tools and techniques

Key management is important if you want your encryption efforts to pay off. You must never hardcode the keys as it becomes easy for the attackers to steal them all. You need to store the keys in the secure containers and avoid storing them locally on the device.

If you are taking all the crucial steps and running all the necessary tests, then the application users will not face any issues and who knows your application might top the list of the trending and secure mobile applications.

Avoid Power Troubles with an Uninterruptible Power Supply System | Desnav.com

UPS stands for uninterrupted power supply system. It has power to run the data driven world and allow it to work smoothly without letting any interruptions or problems come in the way. There are far too many problems in the world and power outage should not be one of them. For the technology hunger generation everything technical and related to science is evolving. Not just technology but ways to run the technology sound and smooth without any hindrances is being worked upon.

There is an increased demand for saving the crucial information in the data driven world. There are dips, fluctuations, spikes; dips can lead to irregularities and fluctuations which will adversely affect your personal data and equipment. With the help of UPS you can provide consistent, clean and uninterrupted .

Backup power refers to the backup plan and to store the backup plan the backup power is really important.

UPS can be of a single or a triple phase of configuration and it can be used to prepare an array of batteries. A UPS can be anything from a little black box that will sit and fit perfectly next to your computer or a multi-ton, megawatt model with a capacity to run big business houses.

Many are not familiar to it but a UPS system can serve multiple of purposes:

  • It helps to refine the quality of power being supplied to the other technical boxes before it reaches the office buildings
  • It is a great backup source for those long term outages when the workstations are put to a halt because of the loss of power supply
  • With the help of UPS there will be no interruptions in the work
  • It is good when the UPS power fails
  • It can be used during the power surges or when there is sudden increase in the voltage
  • During the brownouts too when there is reduction in the supply of power it helps maintain it

The main types of UPS systems are:

A double conversion UPS system

It is powered by the output inverter for a seamless switch and its backup battery is charged by the input AC.

A standby UPS system

It is also known as the line-preferred or the offline UPS. It consists of an inverter, low-pass filter, static switch, battery and a surge suppressor. The system remains on standby until and unless there is a primary power failure.

A line-interactive UPS system

It consists of an invertor or a battery that are always connected to the output and if the power fails then with the help of a switch you can change the electrical flow. The continuous flow of energy provides superior filtering.

The bigger systems usually include power transformers and a switch gear that will provide consistent and a reliable electricity. When there are critical operations it requires a stable, clean and consistent power supply. The UPS also acts as a filter for the flow of power that is coming from the utility source in order to protect against the outages that happen all of a sudden.

No matter where you work and how much your work is technologically driven a UPS will make sure that you don’t lose your crucial data. The various types are as follows:

Data

This type of a UPS is used for applications such as a server farm or the communication center.

Military

Some systems are certified for great quality under the military specifications.

High Temp

Some institutes, people and work environments demand a UPS system that can easily withstand environments that are hotter than the average.

Industrial

Such power systems are used in settings like of a factory or a plant.

Medical

In hospital and various medical institutions there are various machines used all the time and to keep them running UPS systems are required. You must have heard about the life support systems? A life support system helps keep a lot of people battling for life alive. So, no one can afford to turn them off even for a second.

What are the advantages of using an uninterrupted power supply system?

Filter

It helps to refine the power that is coming into the UPS and then it also keeps a check on the power that is leaving the UPS. It makes sure that the internal systems receive a proper and a consistent supply which stays free of all the abnormalities.

Continuity

Whether it is the production line of a factory or computer equipment with a UPS there is no need to fear the outages.

Protection

It safeguards against all the oddities of electricity such as the dips, spikes, surges and failure because of the UPS initially senses those switches and certain things to alternate power before it could become worse and cause any damage to the anomalies.

The lists of industries that can benefit from the UPS system are:

  • Utility Companies
  • Banks
  • TV stations
  • Telecommunications and cable companies
  • Data and call centers
  • Production based manufacturers
  • Universities
  • Electronic manufacturers
  • Hospitals and medical centers

Conclusion:

Your smart technology needs a backup plan too. You need a qualified expert that will help you to explore the various kinds of UPS and can guide you on which product to buy to fulfil the business needs.
