iPhone 4 Security

With the recent release of the Apple iPhone 4, response and demand has been tremendous. However, with so much worldwide use of this device, some concerns regarding the iPhone4 security have been raised.

The problem is that the iPhone 4 uses an operating system called iOS4. This is used on both the iPhone 4 and the new iPad.

It has been reported over the past several months that there are potentially many flaws in this software which can impose large security risks.

This software captures and stores virtually every keystroke and action taken on the device.

It is therefore possible for a skilled hacker to gain access to a wide variety of sensitive information including credit card info, account numbers, passwords, social security numbers, etc.

There have also been a number of other issues reported in terms of the vulnerability of this software to hackers. It was shown how a piece of software developed in Russia can enable someone to gain access to password protected iOS data backups.

The reported security flaws have received attention and concern in limited circles. To date there have been no calls for extensive rewrites of operating software and downloading of patches.

At the same the inherent risk may not be a extensive as some critics claim. However, whether the risk is significant of minimal, it is important to realize that these mobile devices are used extensively by important governmental officials.

The ability to potentially hack into their sensitive data stored on their devices becomes especially important and something to pay close attention to now and over the coming months.

iPad Security – Important to Consider

The iPad has been a very popular new device sold by Apple. If you use this device you may be concerned about the iPad security. Here is some information you might be interested in.

Although Apple has an enviable reputation for producing secure computers, there has been many concerns expressed with the security and safety in devices like the iPad. This device uses a standard called iOS 4.

A recent report indicated that a Russian software was developed which can enable people to gain access to password protected iOS data backups.

Even more disturbing is the fact the iOS keeps virtually a complete log of everything a user types of the keyboard. This includes credit card information, account numbers, etc.

In addition these types of mobile devices require frequent updates which increase the risk of security breaches even more so.

It was reported by a French research firm called VUPEN Security that there are two major flaws which leaves iOS vulnerable. One is a memory corruption error which occurs when is processes a pdf file. And the other is an iOS kernel error.

This means that an app could get low level access to the operating system. Apple has tried to prevent this through the use of private API’s. However this has had questionable benefit.

The risk inherent in these potential security breaches not only affects the average consumer but these devices are used extensively by high ranking governmental officials. The risk inherent is data corruption and hacking is huge.

With the attention focused on these problems, this is something which Apple hopefully is addressing very aggressively and will soon develop effective countermeasures.

Alternative To Passwords and PINs

If you are like many people you do many things online from ordering pizza to banking or stock trading. Many sites require you to sign in and have passwords or PIN number for your protection.

It can be difficult to remember these and it is risky to write them down. Here are some great alternatives to remembering passwords or PINs.

There are programs which store your passwords or PINs securely. If you visit a website which asks for your login information, you can retrieve it from this software by applying a master password.

This means that you don’t have to remember potentially dozens of passwords or PINs to get into a secure site. Of course the risk is if someone gets access to your computer and master password, then they have access to all your stored passwords.

However if you computer is a PC or is normally kept at home, the risk is not as great as if you took your notebook computer with you on trips or to work. It’s something you need to consider but this option is certainly convenient.

There are software packages like RoboForm which stores the website login location and login information. When you enter and store login information, you have the option to password protect this.

A more recent innovation which has been receiving a lot of publicity and is gaining in popularity is securing your information through fingerprint or retina scanning processes.

Both of these methods virtually assure that you are the person authorized to access protected information.

Password protection of the use of PIN numbers is no longer necessary with this option, and your information is protected very well.

However keep in mind that this is a hardware solution and tends to be expensive.

9 Security & Privacy Features Safari has to Offer

Safari was the only browser available for Mac OS until a couple of years ago, and Apple released a Windows version only in 2007. That is not to say the browser isn’t good. It is. It was made by Apple to closely integrate with their Mac OS, so that already says something about its quality.

It looks great and it has enough features to compete with any current browser on the market. In fact it is number 3 by choice in North America (including Mac and PC computers; after Firefox and Chrome; we’re not counting the default installs of Internet Explorer) and is at a tie with Opera in the rest of the world.

Despite having the same security features as the rest of the browsers, it could be argued that it is more secure, mainly because no hacker or scammer pays enough attention to it to actually create a virus, Trojan or malware that would use it to spread to the users’ computers.

Let’s see some of the security and privacy features that make Safari a good choice for a web browser.

Private Browsing. Safari, of course, has its own version of Private Browsing. In fact, it was one of the first browsers to implement such a feature. The drill is standard: anything you view in such a session is deleted, including all traces like cookies and history.

Automatic Updates. Automatic updates are a very important part of any modern program, and Safari is no exception. It will automatically update when a new version is released. The checker works every hour, as opposed to daily on most other browsers, which could be a good thing if there is a serious security hole discovered.

Pop-up blocker. Safari’s pop up blocker is standard stuff, on the same level as Chrome or Firefox. It will block any pop ups except those triggered by the user (by clicking a link or button) or Javascript ones (you can globally disable Javascript if you want to avoid that).

Anti-phishing filter. The anti-phishing filter uses several well known online services plus Apple’s own phishing sites list (which is mainly aimed at protecting Mac OS X users), which may give it an advantage over other browsers.

Global Javascript blocker. The global JS blocker integrated into Safari is a very useful tool that can stop 90% of the viruses and Trojans online. It is best to leave it enabled, and disable it only on sites that you trust. But you can leave it always disabled if you only visit the same sites every day and all of them are trusted.

Third party cookies disabled by default. Unlike most other browsers, Safari has the cookie write disabled for third parties by default. This is a pretty good security measure, as third party cookies are rarely used on today’s web sites and frequently used for scam or phishing purposes.

Manual approval of any downloads. Of course, Safari asks the user if he would like to accept a download every time, for every file. This adds an extra layer of security in the form of the user himself, and if he knows what he’s doing, he’ll figure out a bad file in a moment.

Lack of ActiveX controls. This may be considered a bad thing by some, but due to ActiveX not being used on any modern sites and used for older phishing and virus injecting sites, it is a good thing for your security. Internet Explorer still fully supports this old technology and that makes it vulnerable to such attacks. Firefox and Chrome support it too, but add an extra security level by asking the user to confirm and allow the ActiveX to run. Safari doesn’t have this feature at all, so it is quite a bit safer.

Antivirus integration. And last, but not the least, integration with various antivirus programs. Of course Safari can do it. It can be integrated with everything from the Windows Defender to ESET Smart Security to Norton Antivirus. The antivirus will scan a downloaded file right after it has finished downloading and when you try to open it from Safari. It will be deleted or quarantined if it’s infected, depending on the settings in the antivirus software.

Safari is a pretty good web browser for Windows and Mac, and you can definitely use it without having to worry about security and privacy issues. Too bad it doesn’t have an extensions system and database (sort of like the iPhone apps marketplace). That would instantly propel it to the top of the browsers lists. Let’s hope Apple will integrate this feature in one of the future releases.
