Cyber security provides protection against theft of data, protects computers from theft, minimizes computer freezing, provides privacy for users, and offers strict regulation. Firewalls can be difficult to configure correctly. Faultily configured firewalls may prohibit users from performing any behavior on the internet before the firewall is properly installed, and you will continue to upgrade the latest software to retain current protection. Cyber protection can be expensive for ordinary users. This is chapter helps to understand phases of attacks and types of attacks. Ethical hacking simulates a malicious attack without trying to cause damage. If you need to understand the countermeasures, first you need to understand the phases of an attack. It is necessary to comprehend the steps to counter an attack once it is detected and stop the attack before it reaches the next phase. In general, there are five phases that make up an attack such as reconnaissance, scanning, gaining access, maintaining access, covering tracks.

Improving the cyber security and safeguarding the sensitive data and infrastructures are important to every countries top priority security.
Most people don’t really understand what hacking is about, much less how to go about it. It’s something that we just watch movies or hear about on the news. Companies are now acknowledging the potential dangers of these attacks and thinking of preemptive solutions - one of them being ethical hacking.
Everyone among us has one time or another has come across some form of attack. It could be physical or emotional or of some other kind. The intent is to cause some sort of harm – though sometimes it turn into a blessing in disguise. However, cyber attacks always aim at causing harm.
