8. 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.

9.  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.

10.  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.

11. HOW TO PREVENT THESE THREATS
 1. Cisco Self-defending Network
 long term strategy to secure business processes
both internal and external threats.
 they can protect both their networks, and their
network investments
 , It has 3 main characters, integration, collaboration
and adaptability, integrate into all elements in the
network,
 work together to exchange information,
 use innovative behavioral recognition to repel new
threats

12. Stay Open for Business, Even While Under
Attack
 proven, multifaceted approach protects
from devastating effects of worms, viruses.
 IPSs (Industry-leading Cisco intrusion
prevention systems)can and inspect all
incoming traffic in real time, if found, stop
the threat and prevent it from spreading
though the network.
 Layers of security allows to continue to
respond to clients and stay open for
business - even while under attack.

13. Precaution
 Enable MAC address filtering
 Static IP Address
 Disable SSID broadcast
 Firewall
 WPA2 Encryption
