Encryption

Encryption and science and art of writing messages in encrypted form or in code. And part of a field of study that deals with secret communications, used, among other purposes, to:

• authenticate the identity of users;
• authenticate and protect the confidentiality of personal communications and commercial transactions and banking;
• protect the integrity of electronic funds transfers.

A message encrypted by an encryption method should be private, that is, only those who sent and received that should have access to the contents of the message. In addition, a message should be, that is, the person who received it must verify that the sender and even someone who claims to be and be able to identify whether a message may have been modified.

The current encryption methods are safe and effective and based on the use of one or more keys. The key and a string that can contain letters, digits and symbols (such as a password), and and converted into a number, the methods used to encrypt and decrypt messages.

Currently, cryptographic methods can be divided into two broad categories, according to the type of key used: a single key cryptography and public key cryptography and privacy.

What is encryption of unique key?

Ethical Hacking Training

By Jerry J. Jansen On January 21, 2010 No Comments

Ethical hacking involves computer and network professionals who use their expertise to safeguard the networks of an organization on behalf of its owners. In order to test a security system, they seek vulnerabilities that a malicious hacker could exploit. Ethical hacking is also known as penetration testing, intrusion testing, and red teaming. An ethical hacker is sometimes called a white hat while the other one is called black hat. Ethical hackers collect and assess information on issues like loopholes which are truly a security threat, the depth to which a hacker can get into via one of these holes and the patching requirements in order of priority.

The ethical hacker aims to help the organization take anticipatory measures against malicious attacks by attacking the system himself; all the while staying within legal limits. The most important point is that an Ethical Hacker has authorization to probe the target. The reason is that as technology advances and organizations depend on technology increasingly, information assets have evolved into critical components of survival and need to be protected at any cost.

WinFixer is a Scam That Fails To Fix Anything

By Jerry J. Jansen On January 20, 2010 No Comments

WinFixer is a corrupt anti-spyware program that promises to detect and remove malware and other parasites.  This rogue security program uses alarming security warnings and fake online scanners to convince you that infections are on your PC, which is usually not true at all.  It is purely a scam, and an attempt to get you to give your money away.

This malicious application displays aggressive warnings, alerting you that infections and spyware are on your computer.  The fake online scans detect supposed threats, but these are simply files created by WinFixer to scare you, and they are harmless.  This program claims to detect and remove parasites, but it cannot do either.  In fact, it is a parasite that is potentially dangerous.

By Jerry J. Jansen On January 19, 2010 No Comments

Megapixel cameras are all the rage in the security industry but there are 5 distinct keys to getting the biggest return on your investment when using IP surveillance cameras.  This article examines ways that you can efficiently implement an IP camera system using Megapixel cameras.  Megapixel cameras are often thought of as too expensive or as a fad, but below you will learn how to get a megapixel camera system that delivers remarkable results within modest costs.

1.      Use a Quality Manufacturer

Selecting the right camera manufacturer is arguably the most important decision when deciding to use a Megapixel surveillance solution.  With the relative newness of IP camera technology purchasing cameras from a well known and established camera manufacturer is critical.  Using a camera manufacturer that can deliver on its promise and will be there to stand behind the products for years to come is important for the total cost of ownership of the system.  Selecting a camera based on price or a manufacturer with limited experience may cost much more to replace in just a few short years.
