The motive of the insider attack could be revenge or greed. It is comparitively easy for an insider to perform a cyber attack as he is well aware of the policies, processes, IT architecture and wealness of the security system.  Intelligent Dashboards Company in Sydeny

Moreover, the attacker have an access to the network. Therefore it is comparatively easy for a insider attacker to steel sensitive information, crash the network, etc. In most of the cases the reason for insider attack is when a employee is fired or assigned new roles in an organization, and the role is not reflected in the IT policies. 

This opens a vernability window for the attacker. The insider attack could be prevented by planning and installing an Internal intrusion detection systems (IDS) in the organization.  External Attack: When the attacker is either hired by an insider or an external entity to the organization, it is known as external attack. The organization which is a victim of cyber attack not only faces financial loss but also the loss of reputation. Since the attacker is external to the organization, so these attackers usually scan and gathering information.An expreicend network/security administrator keeps regual eye on the log generated by the firewalls as extertnal attacks can be traced out by carefully analysinig these firewall logs. Also, Intrusion Detection Systems are installed to keep an eye on external attacks. The cyber attacks can also be classified as structure attacks and unstructured attacks based on the level of maturity of the attacker. Some of the authors have classified these attacks as a form of external attacks but there is precedence of the cases when a structured attack was performed by an internal employee. This happens in the case when the competitor company wants the future strategy of an organization on certain points. The attacker may strategically gain access to the company as an employee and access the required information.
