How to deal with the KRACK Wifi vulnerability

There is a severe flaw in the encryption security protocols in use by wireless networks that could let attackers hijack traffic, inject malware, and even steal passwords. The flaw, known as KRACK, for Key Reinstallation Attack affects every computing platform publicly available today: Windows, Mac, iOS, Linux, and Android.

The attack works against all modern protected Wi-Fi networks,” Vanhoef wrote on the “official” Krack attack site. “To prevent the attack, users must update affected products as soon as security updates become available. Note that if your device supports Wi-Fi, it is most likely affected.”

The good news is that the attack does not work over the internet. The attacker or malicious actor needs to be within the range of the wireless network. This means airports, hotels, and other public wireless networks become extremely high-risk areas for dealing with important or sensitive data.

What do you do?

The first step is to ensure that your home wireless equipment, phones, and computers are running up-to-date software to minimise the risk of an attack. Once you have updates in place, then you’re free to use wireless anywhere. Unfortunately, you will need to avoid using most free and public wireless networks to remain secure until you do patch your client devices.

Android uses encryption to transfer data there is not much danger in using an Android device, even on unpatched networks. So for example, even if someone hijacks the session of your Android device on the wireless network, the traffic from your phone to Google’s servers will be encrypted.

 

Best Practices Sound for Band Directors

Being a great band director is a lot of hard work and practice. It takes dedication to get your students to sound great, and it’s not easy getting that organization together in order to put on a show. Band is highly coordinated, and it requires extreme discipline, especially when travelling around the country. Here are some best practices to keep in mind.

Portable Equipment

You’ll be doing some travel, and your school might have assigned you a vehicle or a budget for this purpose. Make sure the equipment you have to cart around is portable, and fits neatly where it needs to go. Include at least one bag for each student in your ensemble. Portable equipment, like a Bogen amplifier, is essential when you have to travel across state lines, or even just a few miles. It also helps make unloading a breeze.

Set Goals

Set specific goals that measure up to the talent you have to deal with. Make sure that you have some challenges along the way so students stay motivated, but managing expectations and placing the right goals can be important for growth. Not everyone can compete at the top level, but but many can be pushed to persevere and do their best.

Remember the Kids

Being a band director is a rewarding job because you get to spend time doing the music you love with the kids you care about. Try and keep that in mind as you travel to various competitions, and let the stressors roll off of you.

Smart home basics

The basic definition of a smart home is a set of appliances which connect to the internet that you can control or automate remotely. The primary reason for the slow growth of the smart home market is because the requirements for each home differs. Two people will not use the same automation. It is that individuality that makes implementing a smart home a step-by-step process. Here are the various components you will need for a smart home:

Lights

Smart lights can reduce your electricity bill. All smart lights are LED, and you can use your phone to set schedules to ensure that lights are only on when you want them. Also, you can remotely switch off any light. You can get connected-bulbs like the Hue or replace the light switch with a smart-switch.

Smart speakers

Use smart speakers like the Echo or Google Home to control other smart devices, stream music, and for everyday tasks like shopping lists. You can also call for cabs, check the weather, and any of the other thousand skills that exist on the platform.

Plugs

You can make any appliance or device in your house smart with a smart plug. Just like the lights, you can control them remotely. Some smart plugs provide and track power use so you can keep track of what uses the most power in your home.

Cameras

Security cameras are also part of the smart home ecosystem. You can trigger certain automation under certain conditions. For example, you can trigger an alert and switch a light on when a camera detects motion. New cameras like those from Nest can even distinguish the sound of breaking glass and generate an alert.

Should You Trust Digital Wallets?

Summary: Digital wallets are the latest in online merchant accounts. But, are they truly a safe alternative?

The versatility and functionality of digital wallets put them in a league of their own. However, there are still some minor concerns that you should be aware of prior to placing your full trust into this technology. Now, in order to understand whether or not digital wallets are right for you, you’ll want to see what types of challenges digital wallets are facing today and what they are doing to overcome them. This article will cover all aspects of these challenges so you can determine if this new technology is perfect for you.

Secure Technology or Fraudulent Magnet?

First off, it should be understood that a digital wallet isn’t easy for an outside to gain access to. While nothing is immune to outside hackers, digital wallets utilize an advanced encryption method to ensure that each and every transaction remains private and secure. This brings up the point of finding a secure platform to work with. Be sure that every merchant account provider that you look into has the latest in security technologies.

Digital wallets never release an account number to a retailer. Because everything is “tokenized”, which means that the transaction takes places within a single session, you’ll find that it leaves behind little to no trace of personal activity. Now, every transaction number is unique and no account data is attached to it, so thieves are less likely to try and snuff out an account number or any other valuable data that links directly to your funds. Without access to this data, cyber criminals are less likely to gain access.

App-Based Digital Wallets

Another security implementation that digital wallets are using these days is password or fingerprint technologies. Since most digital wallets are based on mobile apps, they’ll require you to create a secure password and/or input a fingerprint for access purposes. Keeping your phone on you at all times is relatively ideal to keep your wallet protected, but it doesn’t beat creating a secure password.

Most of the time, thieves that gain access to accounts do so by breaking a simple password like “rabbit4” or “Jeremy1”. Instead, if it allows, combine numbers, letters and symbols to maximize your account’s security – and be sure to write it down in the case you forget it. Doing this will deter hackers from gaining access to your account and stealing personal information and funds. Remember, you always have the option of resetting your account remotely by logging into the app from a desktop or laptop.

Why Technology Designers Play a Pivotal Role in Successful Command Centers

Summary: Working with technology designers can save you money, time, and effort on your command center project.

Technology designers plays a key role in the overall success of a command center. Just like architects and engineers have an indispensable place within the overall design, the technology designer is now a critical component to a successful output.

Leaving the Past Behind

This is more of a non-traditional approach to design – essentially moving away from the 20th century way of thinking. This may require some adjustment in the thinking of clients, architects, and the rest of the team, but it’s also an absolute necessity when it comes to successful command center projects – which ironically relies on technology to thrive.

The Technology Designer Must be Involved from the Get-Go

The time to utilize a technology designer is at the beginning stages of the project, never in the middle or towards the end. The reason behind this is that the technology designer can assist the owner in making strategic decisions which will have a significant impact on the overall success of the project. For instance, say you bring in a technology designer to take a look at the blueprints that the architect has drawn out and sees major flaws. It’d obviously require a redesign and because you haven’t started the construction phase yet, it shouldn’t pose much of a threat to additional costs.

Remember, a technology designer can discover things like insufficient data centers, flawed video display placement, and inappropriate space, which all correlate to productivity and functionality. By catching problems like these and changing the design early on, thousands and thousands of dollars, along with months of wasted time and effort, could be saved.

Amazon faces hurdles in Singapore

Amazon is making a big push into Southeast Asia, and its new venture in Singapore is already facing some hurdles. There are two problems for Amazon in Singapore. The first is that Singaporeans have a lot of shopping malls and prefer to shop in physical stores. The second issue is that rival e-commerce operations like Lazada and Alibaba entered the market a long time ago.

Unlike other countries, Singapore is a unique country where a shopping mall is only a few minutes away. Most people use public transport and phase little in the way of congestion. There are too many stores, and retailers are starting to scale back slightly. With a retail presence around the corner, very few of the islands shoppers buy online. Last year, only 4.6% of retails sales were online.

“Singapore is a very small city-state, so shopping is one of the favorite pastimes for all Singaporeans,” said Chan Hock Fai, a fund manager at Amundi Asset Management. Because retailing is a more mature market in the country, compared with emerging retail and e-commerce markets, “growth rates are harder to come by,” he said.

A report by Google and Temasek Holdings projects e-commerce in Southeast Asia to reach $88 billion by the year 2025. Amazon began its Singapore venture with Prime Now, a two-hour delivery service:

“We’ve launched Prime Now in 50 cities across nine countries, and Singapore is our biggest launch ever,” said Amanda Ip, a spokeswoman at Amazon Prime Now. “We are grateful for the exciting response from customers.”

Outsourced Vs. In-house EDI: The benefits and drawbacks

One of the biggest decisions from a business standpoint is choosing between purchasing software for an in-house EDI implementation as opposed to going with an outsourced EDI service bureau. Below, we look at some of the benefits and drawbacks of both options:

Outsource

Benefits

One of the immediate benefits is the cost savings from identifying and eliminating bad business practices.

Access to the latest technology. When you use a SaaS model, the latest technology is available immediately.

There is a focus on the customer relationship and business rather than the technology itself

Drawbacks

There is an implementation fee

You will need to pay for any transaction, including changing information.

There is no way to know in advance how much time to purchase for mapping business functions and data.

No way to expedite the queue for transactions.

In-House

Benefits

Lower long-term costs as you only pay upfront and do not pay per transaction.

A much greater control of information, as data is not sent to a third party.

Greater business partner satisfaction

Drawbacks

The high initial capital expense for the software and any work to connect existing software.

Requires personnel with knowledge of EDI to manage the in-house systems and troubleshoot issues.

Regular maintenance costs and upgrades will incur separate costs.

The Role of Information Technology in the Healthcare Industry

Summary: Information technology plays a crucial role in keeping records on file when it comes to patient care.

Without a centralized record at a medical facility, there isn’t clarity when it comes to treatment or medication. For instance, let’s say you take a family member to a consultation. The doctor then asks whether he or she’s had an MRI recently. Your family member responds with an unsure “no” because he or she doesn’t remember receiving one. To be on the safe side, the physician then schedules an MRI again to ensure that the results are to be had.

A Centralized System Benefits All Parties Involved

What many people do no understand is how much attention to time and detail it takes to manage one’s health care when a problem arises – which is a lot. It’s quite common for doctors to prescribe numerous medications and tests. However, with a centralized medical record, files can be pulled up and duplication can be avoided. This redundancy also adds to the high costs of obtaining health care in the first place, so why add to it?

An EOC building can assist the record-keeping system by keeping a staff of IT members on hand to take care of the entire medical system. Information technology has the potential to provide doctors a much more complete picture of the patient that they are tending to, as well as providing patients with a much easier way to access their medical history. This works hand-in-hand and benefits both parties involved.

Amazon’s secret to cheap, non-refrigerated food

Amazon is making a strong play for the food and grocery business. Amazon has taken several steps recently to compete with giants like Walmart for the nations grocery business, including a $13 billion acquisition of Whole Foods and launching its meal-prep box line. Now, Amazon is looking to the military for an edge.

According to a report by CNBC, Amazon is looking at a technology that the military uses to prepare, store, and ship food. The online shopping giant hopes the technology will allow it to prepare and sell tasty meals that do not require refrigeration.

The technology, known as MATS, is a development by the Washington State University. The entire purpose of the technology was to provide a meal system for the military that does not require refrigeration, has adequate calories and can be efficiently stored and shipped.

MATS stands for microwave assisted thermal sterilization. The process takes sealed fool packages and places them in sterilized water and then heats the packages using microwaves. This process supposedly does a better job of retaining the texture and flavor of sterilized foods.

Amazon wants a piece of the frozen and prepared food market. The global frozen food market is worth approximately $250 billion, and a third of that accounts for ready-to-eat meals. If Amazon can perfect the use of MATS for meals, it will have a whole new way of attacking the market.

According to the report, Amazon will debut the new service next year if the technology gets FDA approval.

An intro to data center cooling

Summary: Modern data centers are complex systems that mostly use cold and hot aisles to cool equipment. The recommendation is to maintain a temperature of at least 70 to 75 degrees although Google now runs its servers at 80 degrees.

The modern data center is a remarkably complex system that runs hundreds of thousands of servers. Keeping the running efficiently and safely requires maintaining the correct temperature at all times. Any drastic increase in temperature can cause the formation of condensation which can lead to moisture and damage to the equipment.

Most data centers place racks in a particular method to form cooling corridors. Cold air runs along the intake of the servers which is usually on the front and extract the hot air from the rear. It is important to maintain proper rack hygiene and avoid hot leaking to the cold intake lane.

There is a recommendation to maintain a temperature of between 70 and 75 degrees in data centers to prevent any issues. However, there are some studies to show that 70 and below might be a waste of energy. The only reason to maintain a lower temperature is if the latency to backup cooling is high.

Companies like Google maintain servers at 80 degrees and others are now following suit. However, it is important to note that this is only applicable to large data centers and to the expected life times of the equipment.
