It is wise to have secure systems to safeguard computer information, software and hardware just in case they are damaged or stolen.
The attackers gain control but there is to protect any harm that may occur through access of code and data injection as well as the network access.
Attackers in security field has grown into prominence since every computer relies on its systems and the internet including Wi-Fi, Blue tooth and other wireless networks to do so.
It is vital to check out the internal control, operations implementation and the weakness of the design since this is where there is vulnerability in such database.
Vulnerabilities are frequently exploited and hunted by using automated tools which may be manual and utilizing scripts that are customized and before trying to protect a computer it is vital to know what attacks may be made and the kind of treats that are normal.
Poor designing might permit illegitimate access for attackers to do malicious damages in spite of the knowledge that the existence motive is known since they are secret methods known as cryptosystems.
The attackers users block at once and there are other methods that attacks may happen where large points in terms of numbers are delivered at the same time and this makes it impossible to give protection and these kind of attacks comprise of botnet or zombie computers where systems that are innocent are fooled to send traffic to victims.
Some attacks may compromise the protection of the internet by using wireless mice, covert listening devices, key-loggers, software worms which may be installed as well as making modifications of operating systems but even when these systems are protected there may be chances of by-passing the protective measures by booting other operating systems and having encryption which is usually designed for that matter is very idea.
Attackers of any computer may want to get physical, access to all the data and they may copy it directly and this may actually compromise its security since it will be possible to eavesdrop and be able to listen to private conversations between the user and the network but there are means of ensuring that this does not happen by checking the electronic magnetic transmitted by the hardware.
Other IT attacks comprise of email spoofing, biometric spoofing where an attacker may provide fake samples of biometric so as to pose as a different person but is actually not the valid user of the account.
