There is requirement to have some assurance of the need to have secure safeguard for their information, software and hardware just in case they are damaged or stolen.
The provision of computer security services in this field is termed as cyber security which comprises of the physical entr?e from the hardware as well as its control so as 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.
Security of IT starts with the internal control, operations implementation and the weakness of the design since this is where there is vulnerability in such database.
It is vital to know what attacks may be made and the kind of treats that are normal.
Sometimes the imminent knowledge that the existence motive is known because they are secret methods known as cryptosystems.
There are other times when the attackers overload the ability of an internet or computer and here all the users will be blocked 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.
There are probabilities of by-passing the protective measures by booting other operating systems and having encryption which is usually designed for that matter is very idea.
To ensure that eavesdropping does not happen is to make certain that by proper checking of the electronic magnetic transmitted by the hardware is done.
There is also the method of spoofing where an attacker may masquerade as having the valid data including the user name so as to get access to resources and private information and they also include 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.
