Northern Ireland Internet Training Course



 


'Internet Security & Firewalls'


Systems utilising the powerful facilities of the Internet are being deployed extensively in many spheres of activities. Unfortunately, as inter-networking increases, so do the risks from hackers, fraudsters and malicious Web site owners. Despite the fact that there are millions of hackers actively engaged in damaging endeavours, there is a general lack of awareness and understanding by the general public of the dangers involved in using Internet technologies. 

Many Internet based systems and interfaced networks are vulnerable to attacks. Internet insecurities can take many forms; these include brute force frontal denial-of-service attacks, eavesdropping, data tampering, masquerading, malicious content delivery of Trojans, worms and viruses, unauthorised user profiling, industrial espionage, etc. A major concern is the security of systems and supporting networks that handle sensitive personal and corporate information, such as credit card details and critical large-scale enterprise databases.
