This scenario is more common than you think and could easily happen to anyone, especially those who harbor stubborn myths about cyber security. 

Myth #1 - underestimating your appeal to hackers 

If you're tossing your hair back, saying, "Well, I don't have anything a hacker would want," think again. Hackers aren't picky eaters. They'll feast on any bit of data they can find. Your banking details? Yummy appetizers. Personal information? A delicious main course. 

To hackers, we're all just meals waiting to be devoured. The fix here is simple: Take digital threats seriously, set up a sound security system, and be mindful of what you share online.

HOW TO ADD SAFE BROWSERS TO YOUR MOBILE DEVICE

Solution #1 - use identity theft protection 

In the quest for robust protection against these lurking cyber threats, there’s a beacon of hope. Identity theft services. Identity theft protection companies can monitor personal information like your home title, Social Security Number (SSN), phone number and email address and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals. 

One of the best parts of using some services is that they might include identity theft insurance of up to 1 million dollars to cover losses and legal fees and a white glove fraud-resolution team where a U.S.-based case manager helps you recover any losses.

Myth #2 - relying on password strength alone 

For all those confident souls who think a strong password is all the protection they need, here's a wake-up call: Hackers have become more intelligent. They've got tools and tricks to crack even the most complex passwords. 

BEWARE OF CHERRYBLOS, THE ANDROID MALWARE THAT STEALS PASSWORDS

Solution #2 - use strong and unique passwords  

Create strong passwords for your accounts and devices, and avoid using the same password for multiple online accounts. Consider using a password manager to securely store and generate complex passwords. It will help you to create unique and difficult-to-crack passwords that a hacker could never guess.  

It also keeps track of all your passwords in one place and fills passwords in for you when you're logging into an account so that you never have to remember them yourself.  The fewer passwords you remember, the less likely you will be to reuse them for your accounts. 

What qualities should I look for in a password manager? 

When it comes to choosing the best password manager for you, here are some of my top tips: 

• Deploys secure
• Works seamlessly across all of your devices
• Creates unique complicated passwords that are different for every account
• Automatically populates login and password fields for apps and sites you revisit
• Has a browser extension for all browsers you use to automatically insert passwords for you
• Allows a failsafe in case the primary password is ever lost or forgotten
• Checks that your existing passwords remain safe, and alerts you if ever compromised
• Uses two-factor authentication security

Myth #3 - the antivirus illusion 

You got antivirus protection? Awesome! But remember, not all antivirus software is created equal. Some may provide better protection and performance than others, so choose wisely. And if you are running a free antivirus program, consider replacing it for these reasons. 

Solution #3 - have good antivirus software on all your devices

For sure, the best way to protect yourself from having your data breached is to have antivirus protection installed on all of your devices. This will make sure you are stopped from clicking on any potential malicious links that may install malware on your devices and allow hackers to gain access to your personal information. 

See my expert review of the best antivirus protection for your Windows, Mac, Android & iOS devices by heading to Cyberguy.com/LockUpYourTech   

Myth #4 - trusting all apps from official stores 

It's time to also address the belief that only downloading apps from official app stores is 100% safe. Here's the thing: official app stores do offer a safer environment, but they're not invincible. Some malicious apps can slip through, disguised as popular apps. A little extra caution won't hurt here. 

Solution #4 - smart app selection: investigate before installation  

Before downloading an app, do a little detective work. Check reviews, ratings, developer details, and app permissions. You will likely find this information at the bottom of the description page of whatever app you are attempting to download from the App Store or Google Play store. 

Myth #5 - overconfidence in WiFi passwords 

TOP APPS TO TROUBLESHOOT YOUR WI-FI SIGNAL

Have faith in your WiFi password? It’s time to go a step further and boost your WiFi security. With Cyber threats becoming increasingly sophisticated, enhancing your WiFi security measures can safeguard your personal data and prevent unauthorized access to your network, ensuring you're more protected when you're online. 

Solution #5 - effective measures for a safer WiFi network  

Enabling encryption: By enabling encryption, such as WPA2 (Wi-Fi Protected Access 2) or WPA3, you can ensure that the data transmitted over your Wi-Fi network is encrypted and not easily accessible to unauthorized users. Encryption adds a layer of security by encoding the data in a way that can only be decrypted by devices with the correct encryption key. 

Changing default passwords: Many Wi-Fi routers come with default usernames and passwords set by the manufacturer. It is crucial to change these default credentials, as they are widely known and can make your network vulnerable to unauthorized access. Choose strong, unique passwords that are not easily guessable, and use a password manager, as I detailed above. 

Using a Virtual Private Network: A VPN establishes an encrypted connection between your device and a remote server, routing your internet traffic through the VPN server. This adds an extra layer of security and privacy to your Wi-Fi network, as the data transmitted between your device and the VPN server is encrypted. It can help protect your data from potential eavesdropping and provide anonymity by masking your IP address.

Myth #6 - regularly updating your software and devices is challenging and hard to do 

Despite the myth that it is difficult and time-consuming to update your software and devices, it is very easy and doesn't take a lot of time. You do not want to neglect those software-update notifications that pop up on your devices. Updates often include important security patches that fix vulnerabilities and protect against the latest threats. Keeping your operating system, apps and antivirus software up to date is crucial in maintaining a strong defense against cyberattacks. 

Solution #6 - embrace updates for enhanced protection 

Set your devices to automatically install updates or make it a habit to manually check for updates regularly to ensure you're running the latest, most secure versions. And don’t forget to always back up your devices if you should ever need to restore them. Remember, an outdated system is an open invitation for hackers. It's like leaving your doors unlocked when you go to bed. 

Kurt's key takeaways 

It's always better to be safe than sorry. With these cyber security myths busted wide open, it's important to remember that digital security isn't a set-and-forget deal. It's more like a perpetual chess game, and you always need to stay a move ahead of the hackers out there.

6 Fun Facts About Dell Technologies You Might Not Know
Ahead of the first Dell EMC World, here are six fun facts about Dell Technologies, including its environmental efforts, sports sponsorships and its high profile in television and movies.

As ISRO prepares for the launch of Chandrayaan-3, there are many questions in the minds of people about the mission. Here are some questions and their answers. 

What is Chandrayaan-3? 

Chandrayaan-3 is the name of the spacecraft to be sent to the moon by India’s space agency, ISRO. 

We come across many terms such as LVM-3, propulsion module, lander, rover, and instruments like RHAMBHA. It is a bit confusing. What are all these, and which of these is called Chandrayaan-3? 

LVM-3 is the the rocket that will take Chandrayaan-3 up and drop it at a certain point above the earth. With that LVM-3’s job would end.  

From that point, Chandrayaan-3 will journey towards the moon. 

The spacecraft consists of two parts — the propulsion and the Lander-rover modules. The propulsion module’s main job is to take the lander-rover payloads to the moon. You can think of the propulsion module as a truck and the lander-rover payload as the cargo. 

After reaching the vicinity of the moon, the lander-rover payload will detach itself from the propulsion module and falling on to the moon. The lander has engines that will slow down the fall, so that it descends gently onto the moon rather than crash-landing on it.  

The rover is a tiny, trolley kind of device with wheels. Once the lander lands on the moon, the rover will slide out of the lander’s belly and crawl over the moon’s surface.  

Both the lander and the rover have instruments for experiments, such as analysing the moon soil, checking how the moon’s surface conducts heat, and how quake waves move through the moon surface. 

Watch: Why Chandrayaan-3 is important for India’s space dreams

Why does Chandrayaan-3, like Chandrayaan-1 and 2, take a month to reach the moon, when fifty years ago, the United States’ Apollo spacecraft reached the moon in four days? 

We can also shoot off a rocket straight to the moon. Only, the rocket will have to be extremely big. To travel the distance of 384,400 km, the rocket will have to carry enormous amounts of fuel. The fuel adds to the weight of rocket, so it would need to be more powerful. The Saturn V rocket that took Apollo 11 to the moon in 1969 stood 363-feet tall. The LVM-3 is 142-feet tall. Big rockets are very expensive. Besides, there is no urgency, there is no need for the Chandrayaan-3 to reach the moon fast. That is why it takes a route that makes use of the gravity of the earth to sling itself towards the moon. 

The Chandrayaan-3 circles the earth many times before it reaches the moon and then circles the moon many times before the lander detaches itself from the propulsion module and descends onto the moon surface? Why this peculiar route? 

Kepler’s second law of planetary motion states that the imaginary line that connects a planet and its satellite sweeps equal areas in equal intervals of time. This means that the satellite travels faster as it approaches the planet and slows down as it moves away, while moving in an elliptical orbit. The law also means that the farther an object approaches the planet from, the higher the velocity it acquires as it comes closer to the planet. We want to make use of this property to get Chandrayaan-3 enough velocity to shoot off towards the moon. 

So, after the LVM-3 puts it above the earth, Chandrayaan-3 will start circling the earth, on its own, in an elliptical orbit. When it reaches the farthest point, engineers on the ground will nudge it slightly to change the direction a little so that its next loop is bigger than the first. So, when the spacecraft approaches the earth on its second loop, it will acquire a higher velocity. Again, when it reaches the farthest point, called apogee, the engineers will once again change the direction a little, so that on the third loop, the spacecraft acquires an even higher velocity. On completing 5-6 such loops, the spacecraft will have acquired enough velocity to sling itself towards the moon. 

Once it reaches the moon, the reverse will happen. Loop-by-loop the spacecraft will get closer to the moon. When it is about 100 km from the moon’s surface, the lander will detach itself and begin its descent onto the moon.

How does the lander descend onto the moon? 

The lander actually ‘falls’ on the moon. But it has four thrusters — or engines — which will provide it an upward thrust and slow down its descent. It is calculated that just before the touchdown, it will be traveling at a speed of 2 meters per second.  

We have seen spacecraft sent to Mars, like Curiosity and Perseverance, slowly parachute down, but there is no parachute in our moon missions. Isn’t parachuting down simpler and cheaper than using engines to slow down the descent? 

That is because Mars has an atmosphere, while the moon doesn’t. Yes, the Martian atmosphere is thin. The average atmospheric pressure is about 1 per cent of Earth’s. But still there is an atmosphere, which is, by the way, made of carbon dioxide. You need some air to be put under the parachute — to provide what is called ‘drag’. Mars has some, the moon has none.  

What happens after the lander touches down on the moon surface? 

After the lander has soft-landed, it will make sure everything is okay. Then, figuratively speaking, a sort of a trap door under the lander will open and guiderails will slip out of it. The rover will slide down the rails to the moon surface. 

What is the rover and what does it do? 

Equipped with wheels, the rover will crawl around the moon’s surface like a cockroach, pick up soil and do experiments, punch a probe a foot down the surface to check thermal conductivity. Instruments on the lander will also do experiments. Basically, these instruments check-out the moon, to know more about it. 

Do the lander and rover return to earth? 

No. The propulsion module, the lander, the rover are all up there forever. Unless some day an astronaut lands on the moon and decides to bring them back as souvenirs.  

The lander and rover do experiments and analysis. How do we, on earth, get the information? 

They digitize the data and transmit it in the form of electromagnetic waves, to a receiver on the propulsion module, which is still circulating the moon. For back-up, we still have the orbiter module of Chandrayaan-2, the previous moon mission, which also has a receiver. The propulsion module or the orbiter will transmit the data to the earth. 

Is the method of sending information like how radio stations broadcast, say, a running commentary? 

No. Broadcasts are done through audio waves, which need a medium — the air — to propagate. Signals through space are sent in the form of electromagnetic waves — such as radio waves or microwaves — which are progressions of energy. They don’t need a medium to travel. 

Howlong will the lander and rover function? 

The lander and rover will be alive for 14 earth days, which corresponds to one moon day. When the moon rotates one full round on its axis, the earth would have completed 29.5 days. A moon day is about 14 earth days, as is a moon night. Since the solar panels that provide electricity to the lander and rover need sunlight, they will be alive for one moon day, which is 14 earth days.

What is the cost of the Chandrayaan-3 mission? 

The Chandrayaan-3 is estimated to cost around Rs 615 crore. 

What is the significance of Chandrayaan-3? Why go to the moon at all? 

For decades after the US Apollo missions, mankind ignored the moon. But now, after the presence of ice in the southern polar region of the moon has been conclusively established, there is renewed interest. Ice means water, water could be split into hydrogen and oxygen, both of which are rocket fuels. This means, in future, rockets could be built on the moon and powered by locally produced fuels, for other space missions. It is easier and cheaper to launch deep space missions from the moon, because of its low gravity, but this wouldn’t have been economically feasible if you have to carry rocket fuel from the earth to the moon. 

Q: Who is allowed to submit or enter final grades?

A: Final grades must be entered or submitted online via myPurdue Faculty Self Service or BrightSpace by the instructor of record for that course.

Q: How do you know that you're an instructor of record?

A: Log into myPurdue and look in the My Course channel from the Faculty tab. If you have access to course lists, you will see your course offerings. If all do not appear, select the more link under your visible courses.

Q: What if I make a mistake or need to change a student’s final grade after I have submitted it?

A: Grades can be resubmitted through myPurdue or BrightSpace as often as you need up to the deadline. Corrections after that will require a Form 350 or a change submitted using the Grade Change Workflow in myPurdue.

Q: I keep getting the same final grade roster when I click Final Grade entry.

A: Scroll to the bottom of your final grade page and look for the link called "CRN Selection". Click on it and a drop down for all the courses you are faculty of record will display. Click on the arrow for a full list. Select your next CRN, then hit Submit.

Q: When can students see grades in Banner/myPurdue?

A: Students will be able to view grades after they have been rolled to academic history. That process should be complete by 8:00 a.m. the morning after the grade entry deadline.

Q: Can grades be printed?

A: To print a copy of grades for your records, click on "download course roster" from your final grade page.

Q: How can grades be viewed after grades have been rolled to history?

A: Faculty may view their grade rosters again after the deadline has passed and all end of term processing has completed in myPurdue. This is typically by 8:00 a.m. the following day. Grade reports are available using Cognos – Public Folders-Validate-Grades through the schedule deputy in each department for faculty.

Q: What if I have a Pass or No-Pass class?

A: A grade of Pass (P) or No-Pass (N) may be used if the course was originally set up with that grading criteria. If you are assigning an incomplete grade for a Pass or No-Pass class, the grade of PI should be given. If you are pushing grades from BrightSpace, the letter grade you push will automatically convert to a P or N based on the rules in university regulations.

Q: How do I handle regular incomplete grades?

A: Incomplete grades are assigned when a student has attended class, but has not completed work and has been allowed time to do so. As before, a Registrar Form 60 must completed for each student with an Incomplete or (I) grade submitted..

Incompletes are not to be used for students who never attended class and are still on the class roster. Failure to complete the class or turn in passing coursework is noted as an (F).

Q: How do I know if I should assign an "F" grade or an "FN" grade?

A: A grade of F (Failing) is awarded to students who complete the course and participate in activities through the end of the term but fail to achieve the course objectives. A grade of FN (Failing/Non-authorized Incomplete) is awarded to students who did not officially withdraw from the course, but who failed to participate in course activities through the end of the term. The FN grade is to be used when, in the opinion of the instructor, completed assignments or course activities or both were insufficient to make normal evaluation of academic performance possible. Note that once the FN grade is entered, the instructor is required to indicate the date the student last participated in course activity at an academically related activity, i.e., the last date the student completed an exam, quiz, assignment, paper, project, or attended class (if attendance was taken).

Q. I have a 2005 Buick Lacrosse and it has been making a clacking, snapping sound when I brake, and 50-100 ft after brake is released. The sound itself seems to come from the from the brake on the left side, and toward the center front in the car. Sometimes if I hit an unforeseen bump which cannot be avoided, I hear the same sound. The mechanic replaced the left front tie rod, but the noise remains.

A. I would start by going on a road test with a mechanic so you both hear the same noise. I suspect that the first repair was on the right track. It is possible something in the front suspension, inner tie-rod end wear is common, stabilizer links, body mounts or even a brake caliper is shifting could be making the noise.

Q. The speedometer is reading way out of normal range (on the dial). Does the dash need to be removed to repair this, or does the speedometer mechanism have to be replaced entirely? Can it be reset?

A. This really depends on the age and type of vehicle. Nearly all speedometers today are electronic and do not use traditional cable drives. The issue could be the speed sensor in the transmission, or a faulty circuit in the instrument panel. A technician with a scan tool should be able to determine is the speed sensor is working properly.

Q. The steering wheel whirrs when I make a sharp right or left turn and the noise seems to be outside the car. Is this a simple repair job?

A. There could be several causes of this noise, from low power steering fluid to a worn or losoe power steering belt.

Q. I own a 2015 Mercedes GLK 250 diesel, which has displayed the check engine light frequently. The dealership has checked this out with repairs and claimed it to be part of the recall for diesel emissions. The recall was completed, and the light still returned intermittently. It frequently occurred after long road trips over 150 miles and with subsequent driving sometimes went off by itself. Mercedes high end repair shops recommended replacement of the entire sensor board since they said it was easier to affect a repair by its replacement rather than trying to replace the sensors individually. This is a very expensive repair. They said that since l am a Mercedes owner, I could afford the expense. Hogwash. Is this a Mercedes engineering fiasco?

A. The first thing that needs to be performed is a test to see what codes are causing the check-engine light. There are some common issues with this vehicle. Some or all of the following could cause a check engine light to be illuminated intermittently. There could be a vacuum leak, damaged and leaking O-rings, damaged water pump impeller, low battery voltage and even contaminated coolant or engine oil. Using the “parts-cannon or shotgun” approach of just throwing parts at the car almost never actually repairs the issue and is certainly not in the customer’s best interest.

Q. I have a 2006 Toyota Sienna, 103,000 miles, runs great, well maintained with no problems. Should I have the transmission fluid changed? As far as I know. The fluid was never changed.

A. Toyota considers it a lifetime fill and unless there is a leak or other issue is good for the lifetime of the car. But you could certainly change it as a preventative measure. If you do use only Toyota or equivalent fluid, not a generic fluid used in some flushing machines. If it were my vehicle and I drove it “normally” I would leave well enough alone.

Q. My Husband’s car was taken to get an oil change and inspection sticker yesterday. They did the oil change but rejected the car for the sticker. The reason was front body rot/rust. A front cross member piece is needed because it is so badly rusted. The car is a 2007 Chrysler Pacifica; do you think one could be found? He loves the car, and it still looks great. Any suggestions?

A. Yes, you can find a good rust free front subframe on eBay motors and other salvage yard websites. The part is $6-$900 plus about six hours labor to install it, plus a wheel alignment. There could be added expenses due to other rusty parts, but yes it can be repaired.

Q. I own a 2016 black Subaru Forester and I need to touch up some scratches. Can you please recommend a good brand to purchase for me to do the job myself?

A. The brand that I have been most happy with over the years is www.automotivetouchup.com Great color match and everything from touch up pens to quarts and gallons. Plus, they have clear coat paint to get the factory finish look. Recently I was alerted to another similar company https://touchuppaintfactory.com which also has factory color match in all size applicators. Like all painting, the preparation before painting is what determines the outcome of the job.

Q. I recently saw a Chevrolet at a car show, it was a small two-door wagon (not a Chevrolet Vega). The car was highly modified with a big V-8 engine. The steering wheel was on the left and I suspect it may have been a Canadian car. Is this enough of a clue to know what it could be?

A. What you may have seen (and I just saw one recently) was a Chevrolet Caravan. The car was from Brazil and sort of a combination of a Chevy and Opel. Sometimes referred to as an Opala, the factory engine was a 2.5-liter, 150 cubic-inch four-cylinder, but over the years many four-cylinder engine were replaced with a larger 250 cubic inch straight six-cylinder engine.
