Samsung Releases Secure Folder on Galaxy Smart Phones

Samsung Releases Secure Folder on Galaxy Smart Phones

By   12:23   4 comments:

Following the recent appearance of the Secure Folder APK for the Galaxy S7 and Galaxy S7 edge, Samsung has officially made the Secure Folder app available from the Galaxy Apps store. 

Secure Folder is supported by the S7 and S7 edge on Android 7.0 Nougat, and Samsung says more devices will be supported soon. The new Galaxy A (2017) devices already support Secure Folder, so it will be devices like the Galaxy S6 and Galaxy Note 5 that will receive support in the future once they get updated to Nougat.

For those wondering what Secure Folder does, it is basically a more user-friendly version of Samsung’s KNOX security solution that lets you create a separate, private space for all your important apps and data. Anything you do inside Secure Folder – creating a document, taking pictures, or making notes – will not be visible during normal operation, which means no one other than you will be able to access this data. Since Secure Folder creates a separate entity for apps used inside, you can have two WhatsApp accounts on a single device, and similarly have two accounts in apps that might not otherwise have support for multiple accounts.

Secure Folder can be downloaded from the Galaxy Apps store if your S7 or S7 edge is running Nougat, and also from our APK archive. Not every region has Nougat on Samsung’s current flagships yet, but the company is slowly and surely getting around to global coverage so it shouldn’t be long before you are able to start using Secure Folder.

The app uses Samsung’s Knox security features to lock the files within, only making them accessible through a passcode or biometric security. 

The only caveat is that you’ll need to be running Android 7.0 Nougat to use Secure Folder, which may or may not be available depending on your carrier of choice. Assuming you’ve got that set, Secure Folder is available now to download from Galaxy Apps.

Five Ways to Secure your E-Mail

Five Ways to Secure your E-Mail

By   09:01   1 comment:

Concerns have been raised after hackers exposed months of e-mails of Sony employees The Sony hack, the latest in a wave of company security breaches, exposed months of employee e-mails. Other hacks have given attackers access to sensitive information about a company and its customers, such as credit-card numbers and e-mail addresses. One way hackers can sneak into a company is by sending fake e-mails with malicious links to employee inboxes.

Here are five simple steps to make your e-mail more secure and limit the harm a hacker can cause:

1. ARCHIVE EARLY & OFTEN

Most corporate e-mail systems allow people to set up regularly scheduled archiving so that e-mails are moved off of the server after a certain number of days.

You can still check archived e-mails on your work computer, but they are no longer easily accessible on websites outside the office or on your phone. That limits hackers’ ability to access those e-mails too. You can make exceptions for e-mails that you want to keep in your active inbox, and they won’t be archived.

2. GET ORGANISED

As e-mails come into your inbox, deal with them. Sort them into folders. This segments your data, requiring an attacker to know which folder to go to, or to take multiple steps to search for wanted information.

Paired with archiving, it also ensures that what the hacker does compromise is limited and known for any future damage assessment. Sensitive information can also be removed from your inbox. For example, delete an e-mail and save what you need to your hard drive or an external drive.

3. KEEP WORK AND PERSONAL MAILS SEPARATE

Don’t use your work e-mail for personal e-mail or activities online. That limits details a hacker can glean about you to conduct more sophisticated attacks targeting you as the entryway into your company’s system.

For example, hackers can learn about your shopping habits or personal hobbies and use those to send a phishing e-mail that appears to come from websites you bought goods from or read frequently.

Phishing messages route you to a fake address and allow hackers to gain access to your system.

4. DON’T CLICK ON UNEXPECTED LINKS

If you receive an e-mail with a link or attachment you weren’t expecting, send the person a separate e-mail asking whether the first e-mail was legitimate.

For links from companies such as banking institutions, hover your cursor over the hyperlink or right—click to show the link’s final destination. Before you click, make sure the address that pops up when you hover over the link matches where the hyperlink says you’ll be sent.

If unsure, use a new window and physically type in the website’s address to conduct your business.

5. IF YOU SEE SOMETHING, SAY SOMETHING

If your e-mail is acting up or a link or attachment strikes you as strange, forward it to your IT department as quickly as possible. Your attention and fast response may prevent someone else at your company from making a mistake. Source: The Hindu

The group responsible for the Sony Pictures hack has apparently sent a new message that mocks the FBI for its investigation into the devastating cyberattack.

An email claiming to be from Guardians of Peace, the group that took credit for last month's attack on Sony's systems, was sent to journalists early Saturday. The email, titled "The data you are interested in," included a link to a Pastebin page with a so-called "Christmas gift" message taunting the law enforcement agency that on Friday officially named North Korea as the source of the hack.

"The result of investigation by FBI is so excellent that you might have seen what we were doing with your own eyes," reads the message, which then links to a YouTube video. "We congratulate you success. FBI is the BEST in the world."

Steps To Reset All User Permissions To Default

Steps To Reset All User Permissions To Default

By   15:45   No comments:

This article will explain how to change the user permission on Windows (Vista and Windows 7) to its default settings.

Use this method only if you have accidentally changed some user permission on your Windows machine . I can't change the permissions back because it tells me that I do not have access to certain folders.

It is very important that if you have created System Restore points try to restore your system back to previous dates on which your system worked without the above mentioned problem.

To reset system permissions, follow the steps:

• You will need to run ‘Subinacl Tool’ to reset the permission to normal.  Download subinacl.msi from the following link, and save it on the desktop.

(http://www.microsoft.com/downloads/details.aspx?FamilyID=e8ba3e56-d8fe-4a91-93cf-ed6985e3927b&displaylang=en#AffinityDownloads)

• On the desktop, double-click subinacl.msi to install the tool.
• Select C:\Windows\System32 as the destination folder.

This step assumes that Windows is installed in C:\Windows. If Windows is installed elsewhere, select the appropriate path to .\System32.

• Open Notepad.
• Copy the following commands and then paste them into the opened Notepad window.

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f

• In Notepad click File, Save As, and then type: reset.cmd
• In Notepad click Save as type, and then select All Files (*.*).

• Save the reset.cmd file to your desktop, and close Notepad.
• Double-click the reset.cmd file to reset the Windows Update permissions. If this gives you any error message, then right click on reset.cmd and choose “Run As Administrator” as shown in the below screen shot. And if you are asked with any question, give Yes to continue.

This step may take several minutes, so please be patient. When the permissions have been reset, you will be prompted with "Finished, press any key to continue."

• Press any key to complete the installation.

Check if you have the right permissions to all the folders for all users.

This works for Windows 7 as well as Vista. How do I restore security settings to the default settings?
