NETWORK THREATS
Network security: Network security consists of the provisions made in an underlying computer network infrastructure, policies adopted by the network administrator to protect the network and the network-accessible resources from unauthorized access, and consistent and continuous monitoring and measurement of its effectiveness (or lack) combined together.
Aspects of security:
Security involves four aspects:
• Privacy
• Authentication
• Integrity
• Non-repudiation
Advantages of Networking
• Sharing files
• Sharing resources
• Sharing programs
• Backups
• Communication
Disadvantages of Networking
• Crashes
It is a disadvantage on a server based network.
• Data security
As all the data resources are all pooled together’ there is a possibility of unauthorized access if security is weak or poorly implemented.
• Privacy
A network may also mean a loss of privacy.
Several types of attacks
Beside the disadvantages discussed there are some ferocious types of attacks:
• Unauthorized attack
• Data theft
• Password attack
• Brute force password attack
• Trojan horse attack
• Spoofing attack
• Session hijacking attack
• Man in the middle attack
• Denial of service attack
