The next area of host-based security is inspired by living systems. In nature, complex living systems have evolved a mechanism to deal with intruders and foreign bodies inside the organism’s space. This mechanism, the immune system, is a highly complex and adaptive machine for identifying and removing pathogens from the organism.
The immune system works by being adaptive and highly variable as well as selective and tight binding. Variability comes from genomic shuffling. The sections of the genetic code responsible for the portions of the antibodies that recognize and bind to antigens is highly variable, with short sequences being randomly assembled. Furthermore, the construction of the proteins that make up these antibodies, which occurs during the translation from nucleic acid to protein, is also error prone by design. This leads to a large number of diverse antibodies that can recognize a foreign body and bind to it.

The rapid development of current technology, especially Information Technology (IT). Lots of positives from this development, but there are also negative impacts of development. One negative impact is that many programs comes with the spread of viruses, worms and malware. Yet, local virus growth are produce, although its not that much powerful but more than 20 new types of virus variants, each day emerge and spread through the internet or the public media such as Internet cafes.
And like the adage that “crime is always one step ahead”, then the virus unknowingly invade our computers have been installed antivirus though. Because it is usually the antivirus will be able to detect the presence of a virus after antiviral developers to get new virus samples.

Behavior limits are a promising area for computer security and can be applied to several different levels of computer networks. The fundamental principle is that a host that is operating under normal conditions acts in a well-behaved manner. Its sequence of actions can be predicted if we have made enough observations about its typical operating environment.
In contrast, a host that has been compromised by a worm will usually act in a manner that is detectably different. Rather than acting to detect those actions that have been associated with compromised hosts, the actions that are linked to normal hosts are enforced.

As promised in earlier article, I’d like to discuss about linux worm detection. Although its not like windows which could be suspected earlier, yet linux are able to diagnose as well.
After Linux Worm have produce itself on rootkit tool to cover up the existence of it in the system, its a very small possibility of knowing the existence of Linux worm, but that does not mean we couldn’t found it.
The following are some ways you can use:

Although linux are consider as free alternative operating system, and not much virus or worm attack it, but doesn’t mean that its free of them. Some worm could infected in linux based operating system and cause some troublesome as well.
Linux worm is a variant worm that attacks on the Linux system, from most Linux worm that has spread and there is no in between, Ramen, Lion, and Adore, had levels of different hazards, considering the purpose of the worm is for the purposes specific, such as: taking the data user (password), change page index.html (defacement).

The title is early detection, what kind of detection. Of course because these site concerning about computer, then its malware detection. Sometimes we just wonder and question our self whether our computer clean and safe from these malware attack or not.
The most early detection on it, is by watching or observing the loading process. If its getting longer then usual, so it might be some program running. If these program are unknown so you better watch out. Other than that some application might start slower and doesn’t work properly, in some case you even don’t get any display on your computer or blank screen. What cause it, lets discuss it more further.

What is computer interaction? If are talking about interaction, so it does concern about human or people interaction. People is the one who operate the computer, or consider it as the brain of the tool (computer). But later, we were introduced to artificial intelligence, meaning the computer are program to think their own doing certain task.
In which there is a formula that task analysis serves to identify the user desires to be poured into a system. Analysis of the task itself has meaning. the process of analyzing how humans perform the task, what they do, the equipment they use, and what things they need to know.
