The Conflicker Worm, which is also known as Downup, Downadup, or Kido was first appeared on October 2008.  The worm targets systems
which run the Microsoft Windows operating system (e.g. Windows 2000/2003, Windows XP, Windows Vista and Windows 2008). Scientists
believe that Conflicker was able to propagate through the Internet and infect more that 10 millions connected systems. The worm was
programmed to communicate with its Bot servers on the 1st April 2008.

With the advent of internet, the companies are going world wide. Naturally, the concept of the enterprise has changed considerably with it.  These days, the companies are getting more and more dependent on the information system. This has however, created an unprecedented surge in the information security.

 

Steps Toward Making Your Computer "Weirdo-Proof"

 It's an unfortunate fact of reality, but children are the most victimized computer users on the Internet today. The good news is that there are some practical steps you can take to protect your children from sexual predators, hackers, and other seedy individuals who want to cause harm. This article will describe a few of them.
 

One of the most widely deployed type of attacks is the Denial of Service (DoS) . The purpose of the attack is not to steal or destroy information. It aims in making the target system unavailable to its authorised users. Attacking an Internet server with a DoS attack may result in the Internet Server software to crash. As a consequence, the local network may stay unprotected to further attacks. The attacks are based on some of the pitfalls that the TCP/IP protocol and some of its implementations posses when handling incoming data.

It’s not in the scope of this post to describe all available Denial of service attacks. These are numerous and change depending on the operating system and/or software used.  Some attacks are based solely on flaws discovered on specific applications (i.e. Apache, Windows,bind).  This post describes only the attacks that take place remotely. Cases where the attacker has already an account on the system (or can gain an account) are not few. For these cases attackers usually run applications on the target that forces the server machines to crash by exhausting their resources (file space and/or memory).

One of the first things that usually hackers do is to scan a network.  Scanning is performed in order to detect the live hosts on a network and to also identify the services that they offer and in many cases the version and type of the Operating System they use. Currently a number of freeware scanning tools exist on the Internet. The most known of them are Nmap and SuperScan. 

The first and more important thing that an IT guy (and not only him)has in mind , is how to store his system/network data, as to maintain a well organized and protected archive , in case of a disaster or if any kind of attack destroys infrastructures.

Backup however is not a simple procedure. Nor is a procedure that can be done by an administrator without proper guidance. It needs to be planed thoroughly and be done in such a way that it will be able to protect sensitive data , but at the same time provide the availability at any time for the administrator to recover data in hours or at the latest in a day or two.

We all have heard of this term as the new security frontier in Technology world. It is a section that is applied on unique human characteristics to identify and authorize access to sensitive area or data, by matching them to an existent database. Those security mechanisms are close to be characterized ,as full proof , since they are based upon our unique life “specifications” , as previously mentioned.

A very interesting article I have  found on the NET......

These days, all communication technology faces the  issue of privacy and identity theft, with Bluetooth being no exception.  Almost everyone knows that email services and networks require security.  What users  of Bluetooth need to realize is that Bluetooth also  requires security measures as well.
 

Spyware is a serious threat to individuals and corporations.  Many corporations spend millions of Euros on technologies and consultation services to get rid of Spyware.For Home Users the case is even worst. Home Users do not usually have the necessary skills and budgte to install technologies in order to protect themself from Spyware....

Do you need to test your backups ? What do you think ? Use the computer data backup tips in the articles to help you become a more IT-aware small business owner.

In this article I will explain how the Internet works, all the way from what goes through the wires and how the wires across the globe connect, to how meaningful activities are performed on your computer.

Unlike other Internet articles, I won't try to explain the history behind the Internet of today it's complex enough, and like me, you probably don't care very much. I also won't be confusing you with highly technical explanations.

SmitFraud is a type of spyware application that is capable of installing itself in your computer through an adware. It has the technical name W32/SmitFraud.A.

Port forwarding, often referred to as .tunnelling. is the forwarding of network ports from one network device to another. This is commonly done using a NAT (network address translation) enabled router or server and another computer within the local network.

There is a theory in law enforcement that goes something like this:

If someone breaks a window in a building, and it isn't fixed quickly, others will soon be broken. As the evidence of neglect builds, vandals will be more emboldened to break into the building and commit more vandalism and eventually destroy it completely.

If, on the other hand, that window is promptly fixed, it discourages further crime because it is clear that someone is watching the store.
