I. Worms and Viruses

- Last year, 75% of small and medium-sized

businesses affected by at least one virus.

- Meanwhile office staffs are also spreading virus

unintentionally by downloading untrustworthy

material.

- Security Systems need to detect and repel worms,

viruses, and spyware at all points in the network.

IIInformation Theft

- Hackers break to steal credit card or social security

numbers in small-sized businesses rather than large

corporations.

- From both inside and outside of the office, there

should be security strategy to prevent theft of

sensitive electronic information.

III Business Availability

- DoS and DDoS attack are one of top most destructive attacks which cause inability to process legitimate traffic, and If more severe, office's credibility is damaged.

- Normally small-sized businesses are less prepared for attacks than large corporations.

- Even a modest attack could result in substantial lost and tax internal resources

and attacks are more sophisticated and stealthier.
