It helps you to stay on top of what’s going on your system and helps you notice the irregularities that may be caused due to malicious software on your machine. Therefore, by being cautious when installing a new software or update is good idea. Install software and updates from trusted sites and give administrative privileges only when required to minimize spread of malware infection.

9. Encrypt and Take Data Backup

Regular or incremental backup is very important as it helps your stay one step ahead of hackers. If your your system is attacked or you are locked out of it you can easily restore the data and work without being bothered about the attack. Creating encrypted backup makes your even more secure as you avoid the risk of attackers taking control of backed up data.

These nine tips will surely help you stay one step ahead of hackers. But they will only work if you use them before anything wrong happens. Because once an attack takes place it is becomes difficult for anyone to stop it. We all know this but forget most of time due to which we suffer a lot. Therefore, it’s better to take precautions beforehand rather than repenting later.

Five Ways The Apple Patent Will Improve Iphone And Ipad Security

A blog post from chúng tôi provides an overview of the Apple patent application. According to the post, the patent technology would enable a variety of security features including “the device taking a photo of the thief (smile now) or recording the thief’s voice,” adding, “Apple’s iOS security is getting so smart, that it’ll even know what kind of vehicle that the thief is using your device in – be it a plane, train or automobile and notify the proper authorities.”

The patent summary explains, “Systems and methods for identifying unauthorized users of an electronic device are provided in today’s patent. In particular, systems and methods for detecting an unauthorized user, gathering information related to the electronic device, the unauthorized user, or both, and transmitting an alert notification to a responsible party for the electronic device are provided.”

While the patent application does mention the capability to remotely determine if an iPhone or iPad is jailbroken, and it describes methods for remotely restricting the capabilities of the device, those two things do not logically lead to the conclusion that Apple intends to remotely disable jailbroken devices–especially considering the fact that jailbreaking has been declared legal from a DMCA perspective.

Conspiracy theories over the lengths Apple will go to in order to preserve its walled garden aside, the patent describes a number of innovative methods for determining if a device has been lost or stolen, and alerting a responsible party. It also provides the means for taking action to prevent unauthorized access to sensitive information on the iPhone or iPad, and gathering details that might help track the device down.

With the methods and technologies described in this patent application, the iPhone and iPad could significantly improve smartphone and tablet security and make a stronger case for business adoption of the devices. Here are some of the ways IT admins would benefit from the technologies described in the Apple patent.

• Detect Unauthorized Use. A photo or voice recording of the current user, or the current user’s heartbeat pattern can be compared to the photo, voice, or heartbeat pattern of the authorized user to determine if the device has been lost or stolen.

• Suspicious Activity. Entering an incorrect passcode a predetermined number of times, hacking or jailbreaking the device, removing the SIM card, or moving some predetermined distance from a synced device could indicate suspicious activity and be used to detect that the device has been lost or stolen.

• Gather Forensic Data. If the device is suspected of being lost or stolen, the current user’s photo, voice recording, and heartbeat pattern can be automatically gathered and sent to a responsible party (such as the IT admin). Other data that could be collected include screenshots, keystroke logs, data sent to the device, current GPS coordinates, or geotagged photos of the surrounding area.

• Method of Travel. The accelerometer of the iPhone or iPad can be used to detect the vibration profile of the device and compare it against known vibration patterns to determine if the device is currently traveling. This method is capable of determining types of movement including walking or running, or traveling by train, plane, automobile, or bicycle.

• Remote Security. In addition to sending the forensic data above, remote security measures would enable the functionality of the lost or stolen device to be limited, and/or Apple’s remote wipe feature could be used to remove sensitive information from the iPhone or iPad.

While the paranoid conspiracy that Apple is out to disable all jailbroken devices is far-fetched, the ability to remotely detect attempts to hack or jailbreak the iPhone or iPad can be a valuable tool for IT admins who need to monitor and maintain the devices remotely.

9 Ways To Know Your Customers Better

It’s an understatement to say that you rely on your customers. After all, they represent the source of your revenue. Your business only really exists because of them. However, as vital as they are to your operation, your customers can sometimes feel like strangers. In order to maintain growth, you have to know your customers better.

Without this essential information, a knowledge gap can develop. Don’t let that happen. It leaves you vulnerable to your competition and can alienate you from the market. Instead, take all the steps necessary to understand your customers as deeply as you can. 

Learning more about the people buying your products and services can lead to unexpected insights. The more information you have, the better you can respond to changing market forces and an evolving business environment. Meanwhile, without the proper intelligence about your clientele, you’re basically throwing darts in the dark. The future of your business becomes a game of chance, rather than a logical endeavor.

With that in mind, here are nine steps you can take to learn more about your customers:

Check Reviews

Finding out about your customers can become a resource-intensive endeavor. However, there are relatively cheap ways of getting some information. In fact, your customers likely already do some of the work for you. All you have to do is read your reviews.

Invest in Customer Service 

Errors and disappointments are bound to happen. But just because the customer is unsatisfied with one particular order doesn’t mean you have to lose them forever. By making sure that your customer service operation is robust and responsive, you can turn otherwise unpleasant encounters into long term growth opportunities.

Sometimes you have to read between the lines to really understand someone. Not every customer is going to be upfront about their needs. As such, you need to trust the people closest to the situation in order to figure out what’s happening below the surface. In the case of your customers, this responsibility falls to your sales staff. Listen to what they have to say. They can give you subtle insights that might not be available through other means.

Social Media 

Social media represents an excellent marketing platform. However, it can be much more than that. Beyond just providing an outlet for your branding content, social media allows you to connect directly with customers and potential customers. You can converse with people, gather intel, and build relationships. Leverage your social media opportunities to learn more about your customers.

Conduct Surveys

Meet in Person 

Host a Party

You work hard to create a sense of community among your employees – conferences, team-building exercises, and, of course, company functions. Those same principles can apply to your customers.

Knowing your customers is all about planning for the future. The more information you have, the easier it is to innovate and to make improvements. Getting to that point means going beyond the single sale. Instead, with every customer, you need to ask yourself “why?” 

Why did they choose you over the competition? How do your products and services fit into their business? How is there industry changing? The answers to these questions will guide your development. Staying curious and current will set you up for long-term growth.
