Digital images mental map

 My meaningful question is… Can you make an image larger than 717 megapixels (the highest number of megapixels in a photo)? and if you can, how would you do it?

2. Free Wi-Fi problem

 2.My brother always uses public libraries conections to do his online works. He has an important job and manage sensible information about clients and business. I think this is not a good idea to use public wi-fi connections to do so… What do you think and why…

I don´t think is a good idea to do that because...

The biggest threat to free Wi-Fi security is the ability for the hacker to position himself between you and the connection point. So instead of talking directly with the hotspot, you're sending your information to the hacker.

While working in this setup, the hacker has access to every piece of information you're sending out on the Internet: important emails, credit card information and even security credentials to your business network so it´s so dangerous for him and the information of his clients

Hackers can also use an unsecured Wi-Fi connection to distribute malware. If you allow file-sharing across a network, the hacker can easily plant infected software on your computer.

Here are some tips so he can protect himself:

1. Turn on your VPN: A VPN encrypts the connections between your device and the VPN server. This prevents anyone who tries to intercept your WiFi connection on an unsecured public WiFi network

2. Check that your antivirus is up and running.

3. Avoid filling in sensitive information (passwords, credit card details, SSN, home address, etc.) while connected to public networks.

4. Scan your devices for malware with antivirus software.

5. Do the work in another moment or with a more secure Wi-Fi (in your house, a friend house, etc.)

1. Problem with messages

1. I have recently received emails and instant messages that look legitimate at first glance. These messages come with URLs that prompt you to input your personal information. In turn, I think It will steal my credentials and use them to access my accounts and personal data. 

This problem is very common and happens to many people these days, but you should not trust or think that it is not a big deal because these messages often trick you into paying and scamming you, getting information from you, hacking and many other things. Therefore the best you can do is: 

1. If you suspect that an email message don't open any links or attachments that you see.  

2. Ignore and report, copy the message and forward it to 7726 (SPAM). This helps your wireless provider spot and block similar messages in the future. 

if you have fallen into the trap: 

3. Immediately change the passwords on all affected accounts, and anywhere else that you might use the same password. 

4. If this attack affects your work or school accounts, you should notify the IT support folks at your work or school of the possible attack.  

5. If you've lost money, or been the victim of identity theft, don't hesitate, report it to local law enforcement.
