Network Security Threats and Protection Models
It addresses security vulnerabilities for individuals and organizations in network-dependent systems, but is incremental in nature.
The paper discusses network security threats by analyzing exploits on typical network components and citing real-life scenarios, and proposes practical safeguard measures including the use of firewalls and intrusion detection systems.
In a brave new age of global connectivity and e-commerce, interconnections via networks have heightened, creating for both individuals and organizations, a state of complete dependence upon vulnerable systems for storage and transfer of information. Never before, have so many people had power in their own hands. The power to deface websites, access personal mail accounts, and worse more the potential to bring down entire governments, and financial corporations through openly documented software codes. This paper discusses the possible exploits on typical network components, it will cite real life scenarios, and propose practical measures that can be taken as safeguard. Then, it describes some of the key efforts done by the research community to prevent such attacks, mainly by using Firewall and Intrusion Detection Systems.
