DFD ( Data Flow Diagram) Working

 

Problem: Private traces can fail, but network gadgets may not detect it. This can result in statistics getting stuck because it can't be rerouted.

Reason: Traditional routing protocols rely on timers, which may be sluggish to come across disasters.

Solution: BFD protocol acts like a quick heartbeat test between routers. If one router would not respond fast sufficient, the issue is detected, and site visitors can be rerouted to the backup line.

Benefit: BFD allows avoid "facts forwarding black holes" by way of quickly switching to backup paths, improving community balance.

CONFIGURATION




Configured Loopback And Assign Ip Address on Router 1

R1(config)#inter lo 0

R1(config-if-Loopback 0) #ip add 1.1.1.1 32

 R1(config-if-Loopback 0) #inter g0/0

R1(config-if-GigabitEthernet 0/0)#ip add 12.0.0.1 30

Configured Loopback And Assign Ip Address on Router 2

 R2(config)#inter lo 0

R2(config-if-Loopback 0)#ip add 2.2.2.2 32

 R2(config-if-Loopback 0)#inter g0/0

 R2(config-if-GigabitEthernet 0/0)#ip add 12.0.0.2 30

 2. Complete OSPF basic configurations.

R1(config)#router ospf 1

 R1(config-router)#router-id 1.1.1.1

R1(config-router)#network 1.1.1.1 0.0.0.0 area 0

R1(config-router)#network 12.0.0.1 0.0.0.0 area 0

R2(config)#router ospf 1

 R2(config-router)#router-id 2.2.2.2

R2(config-router)#network 2.2.2.2 0.0.0.0 area 0

R2(config-router)#network 12.0.0.2 0.0.0.0 area 0

3. Complete interface BFD configuration and associate BFD with OSPF.

R1(config)#interface gigabitEthernet 0/0

R1(config-if-GigabitEthernet 0/0)#bfd interval 100 min_rx 100 multiplier 3

R1(config-if-GigabitEthernet 0/0)#ip ospf bfd

R2(config)#interface gigabitEthernet 0/0

R2(config-if-GigabitEthernet 0/0)#bfd interval 100 min_rx 100 multiplier 3

R2(config-if-GigabitEthernet 0/0)#ip ospf bfd

DOS AND DDOS ATTACK

A Dos (Denial-Of-Service) Attack and A DDOS (Distributed Denial-Of-Service) Attack Are Both Attempts to Make a Computer System or Network Resource Unavailable to Legitimate Users. However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once. ...

Types Of Attack in Network

Common Network Attacks Explained. 1. Overwhelming a Network (DoS/DDoS): Imagine a restaurant that's flooded with too many customers. In a DoS/DDoS attack: A website is overwhelmed with too much traffic. 2. Eavesdropping on Conversations (MitM): Imagine someone listening in on your phone call. In a MitM attack: An attacker listens to your online conversations. 3. Tricking You (Phishing): Imagine receiving a fake email from your bank. In phishing: Attackers try to trick you into giving them your personal information. 4. Finding a Weakness in a Website (SQL Injection): Imagine finding a hole in a fence. In an SQL injection attack: An attacker finds a weakness in a website to steal or change data. 5. Planting a Hidden Camera (XSS): Imagine someone hiding a camera in a party. In an XSS attack: An attacker hides harmful code on a website to spy on you. 6. Guessing Your Password (Password Attck): Imagine trying to guess a friend's password. In a pas...
