How Does Penetration Testing Work?
In the digital age, data can be as valuable as physical assets. Every year, companies spend hundreds of millions of dollars on hardware and software to protect the data located on their computers. A single security breach could mean having trade secrets compromised or customer information in the wrong hands. Passwords, firewalls and encryption are valuable tools in the ongoing battle against those who would attempt to bypass a company’s network security.
Once all of the components of a proper security system are in place, it is proper procedure to run a final test. This test is referred to as penetration testing. The cyberspace version of a military unit conducting war games, the test is an effort to compromise the newly installed security. A thorough test is the best way to reduce the risk of a security breach at the hands of a real threat.
The first step in the process is risk assessment. This is the practice of determining exactly what is at stake. By finding out exactly where vulnerabilities lie, a better picture can be formed as to exactly what a would-be information thief would be after. For instance, if an online retailer has a large database containing sensitive customer information such as credit card numbers or bank information, they can identify those assets as being a huge liability if compromised, as well as a prime target for hackers. Anther example of a potential liability is a company that has gone through great lengths to assemble a list of leads or clients. These kinds of assets are particularly appealing to unscrupulous competitors or hackers intent on blackmail.
After areas of vulnerability are determined, the penetration test can commence. Generally, the first systems tested are those that can be accessed from the outside. Websites, email access points and remote access platforms are the most frequent gateways for security breaches, and as such are the subject of the most intense tests.
In order to conduct a proper test, a security company must not only be familiar with the most current techniques and tools available to hackers and cyber criminals, they must also have the ability to foresee potential methods of bypassing security systems. This will keep a company’s computer system defense one step ahead of those who would wish to do harm. A solid penetration test is the last, and perhaps most important step, in being protected against important data being lost or stolen.

Top Reasons that Data is Gone from Your iPhone and How to Get Lost Data back
While losing data affects everyone who uses an iPhone, especially for those who reply on iPhone for business. It is really an unpleasant experience. And while retrieving the erased data can be extremely difficult to deal with in some cases, preventing against data loss is very important to you.
The reason that data goes missing are varied, but seven listed below are the most common.
1. iOS software update
Some users state that their contacts were wiped when updating to the new iOS, even after restoring the rest of the device’s settings as is the norm. Its recommended that you just hit “update” button left without any security of your content, all you have to remember is to back up your device to either iCloud or iTunes on a local computer.
2. Restore to factory settings
Restoring your iPhone to factory settings may remove all of your personal information like text messages, notes and appointments, although it retains some of its apps.
3. Jailbreak
Jailbreaking your iPhone voids the warranty, and this operation often got stuck in DFU mode. Restoring your iPhone in iTunes will erase everything including SMS, photos, videos etc.
4. Delete data due to mis-operation
Deleting information simply by touching the screen the wrong way, getting rid of unwanted contacts on your iPhone or other mis-operations will make your regret most before backup.
5. iPhone crashing
iPhone crashing like camera library, mail or contact app crashing will put your iPhone into blank screen with Apple sign in white. Then you find all your photos, contacts were gone after it came back.
6. Get your iPhone wet or have it stolen
If you have had the horrible misfortune of having your iPhone dropped in water or stolen, maybe you will see all your valuable information get lost, including contacts, photos, music, SMS, ideas, etc. in a second.
7. Replacing iPhone battery
All flash memory in the phone (except RAM) is retained without power. Replacing the battery has the same effect as resetting your iPhone, be careful with this!
We didnt realize the seriousness of the situations such as the above until we deleted a crucial message on iPhone. But are the deleted files deleted permanently? Users should be aware that highly sensitive data can still be retrieved from either iTunes backup file or iPhone directly some of the time. Below are the steps from recovering lost data via two means.
Restoring from a previous iTunes backup
You’re in luck if you have backed up before you deleted the contacts, just restore from iTunes backup files via iTunes.
Note: Back up your iPhone using iTunes prior to following these instructions. During the following instructions you’ll be advised to erase all data from your iPhone. If you do not back up the data that resides only on your iPhone, such as pictures or notes, that data will be permanently lost.
Step 1: Configure iTunes so that it doesn’t automatically sync with your iPhone when it is connected to your computer;
Step 2: Connect your iPhone to your computer;
Step 3: Open iTunes, right-click on your device and press “Restore from backup…”.
Recovery tool method to retrieve deleted files without backup
Due to the special technology of iPhone, it’s very hard to recover data directly from the iPhone itself, but it’s not impossible. Professional programs such as Fone Rescue, the iPhone data recovery utility (with separate versions for Windows and Mac) can help to retrieve deleted files without backup, it works with all iOS devices including newer iPads, the iPhone 5, and the iPhone 4S etc. Fone Rescue isn’t perfect, but if you’ve accidentally deleted an important photo or file, you know that some things are priceless.
