The mousepad is one of the most complicated thing about a MacBook because it's totally different than any Windows computer. instead of clicking on the bottom left corner, you click down anywhere on the pad, and two finger click for a right click. you scroll up and down with two fingers, and left and right to go to previous or next page. Scrolling or swiping with three fingers will bring you to the desktop or any other open applications.
Pretty much, macbooks are now designed for one hand use. You can even open the lid with only one hand.
There are MacBook manuals on Apple.com that have everything you need to know about them. Go check it out for further information on how these computers work.

Mac OS X has had RSA support built in for some years now so it should be do-able but without details of what software you are using and at what point it fails it is hard to provide a definitive solution. RSA do provide a token for Mac OS X (See links below). Have you tried talking to someone at your company as they may have already solved the problem?

Why is WPA preferred over WEP?
WEP is a part of 802.11. WEP is not secure because its wickness in the encryption mechanism. Which is used by many wireless network scanners. It takes about 5 minutes to hack WEP. It's highly recommended to use WPA or WPA2-PSK AES over WEP.

Do Isohunt torrents contain viruses?
NEVER trust software you download. For example, a downloaded bittorent client added a toolbar i EXPLICITLY asked not to have AND required a system restore to eliminate it. (the clue was that the download of a torrent i HAD NOT REQUESTED was proceeding while i could NOT google).
NEVER trust software you download.
(NOTE: the original answer said something along the lines of "bittorrent client ok, but you can get a virus from things you download".... why did you trust the original bittorrent client download?)
it should be ok but i would go with eBay and craigslist although some people may scam you it is very very slim chance that that will happen
Amazon is a secure site. They are found to be quite reliable compared to eBay and craigslist. Their customer service is responsive when you have an issue related to whatever you ordered.
What is security planning in computer security?
Security planning for IT may involve the development of security policies (ie, acceptable use, disaster recovery, breach notification), implementation of security controls (to include hardware, software, and personnel), risk assessment, cryptographic use and controls, and legal/ethical considerations. It is essentially the strategic view of computer security as opposed to the tactical view that an intrusion detection analyst might have.
How do you fix the bugs in an existing application?
If a application is existing (You bought it or downloaded for free from the internet) then you cannot debug the application because the source codes are hidden and cannot be debugged. If you are talking about missing files then just download the missing file and paste them in the folder of the application.
E-safety (internet safety) involves being safe on the Internet. This includes things like using the latest antivirus, spyware, and firewall software. It includes safeguarding your personal information. It is often wise to avoid putting photos online, since it makes it easier for unsavory people to find you. Not giving out important/sensitive information about yourself is one of the best ways to stay safe. You never know who is on the other side of the computer screen.
Example: John, aged 14 met "Sarah" online. He gave her his phone number, address, date of birth and School he attended. After a couple of days they decided to meet up in real. "Sarah" turned out to be David, aged 46.
How can removable and non-removable media prevent hardware malfunction?
Removable media are used to transfer data between computers, creating backup copies of information and can be used to distribute commercial software between users. Non-removable media is permanently connected to the computer and provides fast access to data. It permits direct access to individual records. So its important to create a backup of data so that when the system crashes the data can be restored.
In the United States of America, intercepting any digital data is paramount to wiretapping, which is illegal except when used in conjunction with a warrant or under the Patriot Act. Actively attempting to obtain passwords can be considered a felony, with hefty fines and jail time for convictions. However, just because you came in contact with a password does not mean it is illegal, as long as it was accidental, and that leaked knowledge was not used to breach any account that does not belong to you. Installing a keylogger is illegal, but your friend saying that 'pancakes' was his favorite password is not illegal unless that information is later used to access their account without permission.
Roaming data means collecting a network or signal from another network provider other than the original signal provider. This is generally used when someone is in abroad.
How much personal info is on your computer?
This is a relative question. There is as much personal information on your computer as you put there. Some people are not as concerned as others and put a tremendous amount of information on their personal computer. Still others vomit up mountains of information on social networking sites.
The key is, if you would not give a piece of information to a total stranger, do not pass it through your computer.

How do you provide password self service for domain users?
If you enforce a password change policy within your Active Directory domain, chances are you know plenty about the increased help desk calls from remote OWA / VPN users who have an expired password and were unable to log on to the domain, email etc.
Typically, most companies use OWA's change password function within the web interface for supporting remote user password changes. However if your password is already expired, your account is locked out, or you are a new user issued a temporary password (change on next login), there is no native method available to allow these users to self-service the issue. They must call the help desk for assistance, and remain unproductive until IT can provide help.
To easily remedy the issue and "empower" remote users with the ability to self-service password resets, account unlocks, and update a temporary password to a permanent one, you'll need to deploy a 3rd party "web based self service" software solution that interfaces with Active Directory. This type of system provides standard users with an external portal to log into and handle issues themselves quickly and securely.
Sounds easy right? The problem is, there are many solutions to choose from at varying price levels. Not all self-service systems are created equal. Some are very secure but impossible to deploy (change control nightmare). Other are easy to deploy but not secure at all, compromising perimeter security. Others are easy to deploy and secure, but impossible to build in fault-tolerance to the system or load balancing. And others still, are so completely baffling for the user to operate that it ends up causing more help calls than it was designed to reduce!!
How do you make an informed choice? Try a lot of different products. See which one works great from a "dumb user" perspective, and is "realistic" to deploy within your secure environment.
Some "not good" product features to avoid, which should help with your selection:
- Require schema extensions / changes to AD in order to function
- Requires windows-only computers and installation of client software to function
- Places sensitive "administrative functions" inside the external web self service portal
- Web self service portal has not been PCI scan tested by the vendor
- Requires SQL or MySQL databases to store user data
- Uses odd butchered versions of open-source code for the web self service portal
- Does not provide for easy failover, load balancing and system redundancy
- Does not log web portal events with specific event ID's to the server for monitoring
- Stores sensitive user data and passwords outside of Active Directory
- Stores sensitive user data and passwords in the external web self service portal
- Web self service portal cannot be deployed in a DMZ outside of the secured LAN
- Software is not designed / built by vendor (product bought from some other company)
- No in-house support (support number goes to Philippines or India call center)
- Uses old, cumbersome "question / answer" methods for user enrollment in the web portal (not effective)
When reviewing products, you should ask the above questions- A proper web based self service solution should not have any (or very few) of the above items present. As a yardstick of successful measure, we suggest Password Reset PRO from SysOp Tools.
With a good web based user self service solution deployed for your users that is secure, easy to install and easy for users to navigate, you will reap the benefits of less help calls, more productive users, and better overall enforcement of a secure change password system.
There are opensource tools that help the Sysadmins to forget changing them and letting the users to do it by themselves. Such as ADiPaRT. It's an Open Source Active Directory Password Reset Tool.
Can a vkey number be retrieved using the MEID or MSID numbers?
Not on a end-user level. Manufactures belive it is impossible. But for use on an educational level and not to be used piracy you can search for a keygen program for what ever you are looking for. Keygens only work for the game, OS, or software they are built for. There is no keygen that works for more than one piece of software. This is for informational or for curiosty purpose only and again not to be used for anything or any reason that is unlawfull anywhere, anytime.
