I always think about the security of Macintosh apple machines. The Macintosh is much better operating system when it comes to security. Why it has edge over others sytems? Some of the reasons are as follow.

1- It has industry standard security software development.

2- The security concern is a central to the design of operating system with smart architecture.

3- Due to open source nature, the problems can be solved easily with the help of ommunity.

4- The default settings makes it difficult to invade to the system or exploiting loophole is minimal.

5- Due to standardise application development, third party software are easy to develop and run on macintosh.

6- Apple respond very quickly if it find any flaw, the patches are released quickly.

The above features are quiet enough to give thumb to Macintosh Apple computers.

what changes should be made to  Mac OS X configuration with respect to security.  “The only significant change which one have to made is that the different password for my Keychain than for my user account.” That’s a change also make on all of  systems. The Keychain allows you to keep internet passwords, notes and SSL certificates in an encrypted store, and synchronize them between different machines with .Mac. So far, so good – of course there is only a single password to unlock all of this information, but it means that you can choose one really good password that you can remember, then use different passwords for all of the websites, mail accounts and so on that you use, which you don’t need to keep in your head (or on a Post-It note) because you can always get them out of the Keychain. The problem with the default Keychain configuration is that this password is synchronized with your login password; whenever you are logged in, the items in your Keychain are unlocked and available to any

application that asks for them. It is simple to fix this: firstly, open the Keychain Access application in /Applications/Utilities. In the Edit menu, choose “Change password for Keychain ‘login’…” and set a new password. Now when an application needs a password out of the Keychain, it has to prompt you for that password; a slight reduction in convenience but with a huge payoff in being able to control when your stored passwords are used. You can also control when the Keychain is automatically locked (so that you get re-prompte0.

Macintosh platform is now becoming the target of the same sort of organized crime that affects Windows users,

these attacks are still very limited in scope and in impact. Nonetheless, we Mac users

cannot afford to be complacent. The success of many data theft attacks depends more on

the target system’s user and the way in which they work with their computer, than on

which operating system they have chosen to install.

Laptops are more prone to physical attack than desktop systems by their nature – being

portable they are often taken out of the office to work from home, on the train or even in

the local Starbucks. When you take your machine out on the road, you also take the data

it contains away from the safety of the corporate environment with its security controls

and into new environments with new risks and threats. Home users too must realize that

when taking their MacBook out of the front door, more of their identity is on display than

simply their preferred laptop brand.

In this paper I describe 10 steps that can improve the security of a Mac system, paying

particular attention to laptop considerations. I concentrate on improving physical security

– that is, protecting the system from attackers who can get their hands onto the

computer.

Are Macintoshes just a “little” more secure? Here’s a good article on a security flaw “discovered” in the last week in Mac OS X 10.4, a vulnerability in the interaction between Quicktime, Java and a Macintosh web browser, including Firefox and Safari. It enables a malicious programmer to potentially control a Macintosh OS X 10.4 system by simply directing the visitor to a specially coded website. As of the writing of this note, Apple has not yet published a security update in response to this “discovery.”

The MacBooks have been set up on their own Wi-Fi network, separate from that of the conference at large. The conference’s Wi-Fi network has been suffering almost continuous denial-of-service attacks since the beginning of CanSecWest, with connectivity breaks coinciding mostly with morning hours before 10 a.m., before the bulk of hackers had managed to drag their (often hungover) bodies out of bed.

Dragos Uiri, the conference’s M.C., announced on Friday morning that the contest had been opened to hackers to try their malicious Web page exploits against the systems. To do so they had only one new avenue opened to them: the ability to e-mail the machines at pwn2own@cansecwest.com.

There is a very good and detailed article .
