Unit Summary

Ethical hacking is the process of finding vulnerabilities in a computer system and network. It is a process which helps in securing computer systems and networks by going through a well-defined process which involves all aspects of reconnaissance, information gathering and analysis and providing appropriate solution. The ethical hacking process is conducted by a security professional who uses hacking tools to gain access to a computer system and network after the hacking has been legally authorised by the organisation. 

We also introduced malware threats and the different types of malwares available. Malware are malicious programs which can cause damage to a computer system. Proper security measures should be adopted in order to avoid proliferation of malware. Different tools are available to detect and remove malware. However an updated antivirus remains the first solution to provide protection. 

There are a variety of network security attacks which happen every day on computer systems and networks. The most common types of network security attacks are Denial of Service Attacks, Session Hijacking and Web Attacks. It is important to understand how those attacks work so that countermeasures could be provided. Otherwise user’s data and company business will be at risk of theft and losses in revenue. This Unit has introduced the various types of network attacks and their counter measures.
