With the development of large open networks, security threats have increased significantly in the past 20 years. The major reason relies on the fact that hacker tools have become more and more sophisticated, while the technical knowledge required to use them has become less and less. Nowadays, the hacker tools include password guessing, disabling audits, back doors, sniffers, hijacking sessions, just name a few.
The network attacks might come from hostile nations, terrorists, criminals, hackers, disgruntled employees, and corporate competitors. Hackers' motivations might include intelligence gathering, the theft of intellectual property, denial of service (DoS), the embarrassment of the company or clients, or the challenge of exploiting a notable target.
As enterprise open their networks to public, they also expose the networks to hacker attacks. This result in tighter security policies. Just imagine the damage posed to an E-bussiness compnay when a credit card information breach happened.
CCENT will ask you to Explain today’s increasing network security threats and the need to implement a comprehensive security policy to mitigate the threats.
Good luck for your CCENT and CCNA exam.
