Computer Security

A person could use the software TrueCrypt or Kakasoft USB security program Or one could buy a flash drive that already has encryption software already installed.

Yes. Viruses that add and delete files are most unwelcome on computers. Rule number 1, backup, backup, and backup. And the backup some more.

it makes their job easier because it calculates for them.

You can prevent theft of data from a computer through using strong passwords.

Sending an encrypted message while other party has the (same) private key to decrypt the message. The trouble is how to transmit the key safely first. Usually there's a third party involved with a public key.

Firstly you will need to know a basic programming language, you cannot go straight into as all "Hackers" are skilled computer programmers. Also you need to have knowledge about the consequences of the act that you may perform.

backups are needed for security reasons for any organization data is most important but if due to any reason (accident , virus ,human etc.) data get corrupt or get loss then it is big problem for organization there for these backups are needed

Try to find out the correct e-mail address.

Make sure the address you sent it to was correct. It could also be a problem with the recipients mail box being full or the server malfunctioning.

The data itself does not matter in this scenario. The type of encryption used is symmetric encryption, meaning that the sender and receiver have the same key to lock and unlock the data.

When data is received by the receiver , receiver send an acknowledgement. After receiving the acknowledgement from receiver , senders knows the message has been successfully sent.

Anything with an exe at the end is an executable file so you should run virus software.

to serve as a organization to give information when people around the world need it for special purposes

Yes, but it would require software that you would have to purchase. There is no real way to do it for free. You will just have to type your password every time.

It is a program to assist you in setting up your home network for things such as printer sharing. If you do not know where it came from, it is often bundled in with routers from dlink and other companies.

If you are asking if you can/should remove it from your computer and startup then the answer would be yes if you have no plans to use it.

The Public and Private key pair comprise of two uniquely related cryptographic keys (basically long random numbers). Below is an example of a Public Key:

3048 0241 00C9 18FA CF8D EB2D EFD5 FD37 89B9 E069 EA97 FC20 5E35 F577 EE31 C4FB C6E4 4811 7D86 BC8F BAFA 362F 922B F01B 2F40 C744 2654 C0DD 2881 D673 CA2B 4003 C266 E2CD CB02 0301 0001

The Public Key is what its name suggests - Public. It is made available to everyone via a publicly accessible repository or directory. On the other hand, the Private Key must remain confidential to its respective owner. Because the key pair is mathematically related, whatever is encrypted with a Public Key may only be decrypted by its corresponding Private Key and vice versa.

For example, if Bob wants to send sensitive data to Alice, and wants to be sure that only Alice may be able to read it, he will encrypt the data with Alice's Public Key. Only Alice has access to her corresponding Private Key and as a result is the only person with the capability of decrypting the encrypted data back into its original form.

To protect the backed-up data from possible loss in the event the main building and the equipment and data in it are destroyed.

The question needs to be more specific. There are many different types of attacks for finding passwords: social engineering, birthday attack, dictionary attack, man-in-the middle, brute force, etc. etc. etc. The "How" is different for each attack.

Depends on the job requirements,

In the USA some broad numbers are anywhere from $45K annually for a relatively unskilled worker.

$250,000 annually for a skilled practioner with experience as a penetration tester, Chief Security Officer who has developed and implemented security policy as strategy and versed with privacy laws and regulations in the USA and international venues.

This same individual will likely have a resume which resembles a master tradesman like a master electrician who started out as systems administrator of Win32, UNIX/LINUX and network operating systems such as Cisco IOS/CatOS who leveraged their extensive system knowledge to approach and design systems from the security perspective while maintaining functionality and with little impact on the end user experience.

The best security practioners are skilled sys admins at the core since this fundamental knowledge is crucial to understanding risk proposition and determining real level of effort when designing security implementations and practices of common technologies.

NASA doesn't train pilots, NASA recruits top military pilots and trains them to fly spacecraft, a top security practioner is the same example.

Certifications make a huge difference, the most common is the Certified Information Systems Security Professional, however the actual exam itself is banal and less challenging then picking your nose with your left hand. More organizations are recognizing the lack of value of the CISSP since too many of them have joined companies and ruined their security and had to be fired because they talked their way into $90K jobs when they were really more like $45k people.

The majority of CISSP's are IT auditors, and the great majority of IT auditors are just financial auditors and accountants "who are good with computers" and have a less than adequate understanding of how to efficiently design systems and the security protecting those systems. These are the kinds of people that find the CISSP exam challenging and have to study for weeks or months since they're really trying to learn the tradecraft for the first time as they're about to take a certification exam which claims to require 10 years of computer/InfoSec experience (but never really verified).

ISC2 who administers the CISSP designed the test around 10 domains, one including ethics which is laughable since the same organization plagiarized a law journal for the Legal domain. Rather sad for a "non-profit" group that charges $500 for a test and they couldn't afford to license or develop original content.

In the context of cell phones, tethering is connecting your phone to a laptop or similar data device using a data cable, usually for the purpose of connecting to the Internet on the laptop, via the phone's wireless connection to the cell phone network.

Carriers usually charge more money for accessing the Internet via tethering, as opposed to on the phone itself. Sometimes this is enforced via technology in the phone, although often it is simply the honor system and not strictly enforced.

Break point is selecting the point from where program will run in debugging mode..

You cannot get rid of the, "win32" application. The reason why, you cannot get rid of the, "win32" application, is because, "win32", is the MOST important application for Microsoft Windows XP, Microsoft Windows Vista, and Microsoft Windows 7 RC, PCs and notebook, because that application helps Windows Firewall work. And also because, "win32", blocks Trojan horses, worms, viruses, and spyware, from hacking into your computer.

To keep viruses from infecting data, keep a copy on an external hard drive that is disconnected from the main computer at all times (except when you are copying over files).
