In cryptography, encryption is the process of transforming information (referred to as plain text) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in cryptography, referred to as cipher text). In many contexts, the word encryption also implicitly refers to the reverse process, decryption (e.g. “software for encryption” can typically also perform decryption), to make the encrypted information readable again (i.e. to make it unencrypted).
In today’s world where much of our personal information and financial transactions are processed via the Internet, data encryption is an essential element to any effective computer security system. This activity is why encryption is important. One of the main reasons why encryption is important has to deal with the way that information is sent via the Internet.
Data encryption was first used by the government, mainly to guard military secrets. In today’s world of Internet businesses, this method of protecting your computer data is being used more and more by financial institutions and other businesses as a means to prevent anyone from gaining unauthorized access to money transfers and other financial matters.
Data Encryption is a way that you can protect your computer data from outside sources. Originally designed to protect government and military secrets, this protection is now being implemented by many types of businesses. Learn about the pros and cons of software based data encryption versus hardware based encryption.
In today’s society, it seems that anywhere that you go there is usually some form of computer accessibility nearby. For the active business person or college student, having the ability to use these devices to access your personal information anywhere that you may find yourself is an important factor to success. A USB hard drive with encryption may be the perfect device that will permit you to have all your data in the palm of your hand.
VoIP, for long, has been termed as a cheap and unsecure mode of communication whereby the voice packets are traversed through public internet. There is control over the packets flow and hence highly unsecure.
This article describes how to utilise NTP authentication to authenticate a time reference when synchronising network time clients to a NTP server.
As consumers upgrade their computers and laptops and are discovering the convenience of wireless computing, they may also be opening themselves up to attacks from random hackers. If you have a home network and it has wireless capabilities one of the most important things you can do to protect yourself, your computers and most importantly your data, is to secure your network.
Wireless networks are threats to your network security. Most people leave their wireless network totally open, without any type of security. These folks are begging to be hacked. But there are others who are utilizing WEP encryption for their security and they think they are secure. I will show you why they aren't.
When something is stored on your computer or sent by email, it means others can get their hands on it. While few of us store secret blueprints for atom bombs on our PCs, we’ve still got information we’d rather keep away from prying eyes: the Excel spreadsheets we use to keep track of our finances, the Word documents that outline our plans for world domination, or the email evidence of our torrid love lives.
Because nobody wants to compromise the integrity of their network by having some hacker "borrow" your bandwidth or gain access and start snooping around you need to lock down your network. Fortunately, encryption is built into wireless technology; it's simply a matter knowing how to turn it on.
Your computer safety and security is not limited to anti-virus software, anti-spyware software, and firewalls, because the passwords themselves can be targeted by unauthorized people. It would be better for your overall security if you take the necessary precautions and means when it comes to dealing with password protection. Learn how you can protect your passwords to all your online accounts that even the hardest hacker cannot dare to attempt to retrieve any of your passwords.
This article describes how to utilise the NTP security features to authenticate time references when synchronizing network time clients to a NTP server.
Wireless networks can be secure like they are wired. You need to know right way to configure them and to use right authentication algorithms.
Are you wanting to apply for a new credit card but feeling hesitant to perform the credit card application online? If so, you need not be concerned. Advances in the technology of secure e-commerce have made online credit card applications literally safer than filling out a paper application and mailing it through the US Postal Service. Here's why.
Because wireless networks can be accessed by anyone with a compatible wireless network adapter, most models of wireless network adapters and WAPs provide for encryption options. Some devices with this feature enable you to set a security code known as an SSID on the wireless devices on your network. This seven-digit code prevents unauthorized users from accessing your network and acts as an additional layer of security along with your normal network authentication methods, such as user passwords. Other wireless network adapters and WAPs use a list of authorized MAC numbers to limit access to authorized devices only.
You have to know how to configure passwords on a Cisco router to earn your CCNA, but you also have to be able to look at a router configuration and determine the existing levels of security. Learn how from Chris Bryant, CCIE #12933.
This article describes the security aspects of the NTP protocol and specifically using MD5 keys to authenticate a time server.
Reliability and security has always been a main concern for all organizations and Service Providers, especially when it comes to business communication. No company wants to make any mistake for building and maintaining relationship with their clients, colleagues, or senior managers.
