Type of Security Issue | Solutions and Technology used | Network Administration Principles |
1. Denial of service attack- | Use Anti-Dos attack technology such as ASIC Dos Mitigation Engines and Network Behavioral analysis (NBA). |
|
2. Traffic spike | Install server –side caching plug-in and extensions to cope with traffic. You can also get a better server or make sure the content is rendered quickly. You can also use a Content Delivery Network(CDN) technology |
|
3. Reflective/amplified attack | Close down your DNS resolvers, implement BCP38 or ask upstream provider to implement it. You can also deploy DNS rate limiting on authoritative DNS servers as a technology. |
|
4. Smurfing Attack | Shut off the broadcasts addressing feature of the external router and firewall. Vantage system is a technology developed that monitors the network for attacks. |
|
5.Physical attack | Use surveillance systems such as CCTV cameras. Use access control, meaning doors and lock and multiple alarms. |
|
6. ARP cache poisoning | Configure your switch to use private VLANs (PVLANS) for optimal security. |
|
7. Packet sniffing attack | Use secure protocols for a start, for example HTTP, SSH. Build the network with a switch technology rather than hub technology. |
|
8. Spoofing- | Configure the firewall and routers correctly to restrict forged traffic from the internet. You can also implement authentication and encryption mechanisms to reduce the threat capability. |
|
9. Rouge access point attack- | Hide behind an Ethernet hub to detect the attack. You can also configure the rouge AP as 802.1x supplicant. |
|
10.War driving- | Encrypt the wireless interaction and filter the Mac address capable of connecting to the router. |
