- In network security, it is important to understand port scanning. Hackers use tools to scan a network and determine if there are open ports and if they contain some sort of vulnerability. To scan ports, you first have to find active hosts on a network. Once you find active hosts and discover a list of IP addresses for those hosts, a port scan can be performed to gather information about open ports and analyze services running on those ports. A port scan is the process of sending packets to an active host's ports and learning details that can help you gain access to that host or to discover open vulnerabilities on your network. Some common ports are: Port 20 - File Transfer Protocol or FTPPort 22 - Secure Shell protocol or SSHPort 23 - Telnet protocol for unencrypted transferPort 80 - HyperText Transfer Protocol or HTTPPort 443 - HyperText Transfer Protocol Secure or HTTPS The Well Known Ports are those from 0 through 1023 We are going to simulate a port scan by filling a list with 100…For DNS query, it is natural to expect that the local DNS server may not know how to resolve an address. In this case, further queries will be made by this local DNS server. If a hacker can find "a way" to make a certain DNS server report back the wrong IP address, then anyone trying to get to one Web address will be sent to a bogus one, without any obvious way for the user to detect that anything is wrong. Likewise, email could be delivered to the wrong destination. 1) Describe two possible attacks to make the resolver report the wrong IP address.In network security, it is important to understand port scanning.

What is the procedure for getting it? What role does it play? What advantages does it offer?FTP port numbers are significant. How did you get to the conclusion that FTP would provide control data "out of band?"
- Is there any other use for SSH other providing remote access? Are there any acronyms for SSH that you would want to put in this list?Since servers on a flat network do most of the company's work, it is crucial to implement a network security architecture to increase safety and security. Since the network is flat, this holds true. time a buffer zone is established. What would you alter about the existing setup of the network if you had the chance?Hackers may attempt to break into a network by switching the source VLAN of the attack traffic with one of the target VLANs. This is done in order to get access to the network. The only way for the offender to be identified is if the normal actions connected with an attack are recognized and investigated. You need to be as specific as possible on the preventative steps that have been taken.
- Even if you didn't give him the password, a neighbor often gains access to your wireless network using a password. Is there a specific error that was missed?Laboratory Exercise Static Routing Objectives: At the end of the exercise, the students should be able to: • Assign IP addresses to PCs and routers; and Check the connectivity of all interfaces using the PING command. Principle: Routing is the basic element of data communication networks in which it is the process of selecting paths on a network along which packets are sent from a source to a destination. Routes are the path information used to guide packet forwarding. Network devices need to forward IP packets from different subnets to their destination IP subnets. Static routes are manually configured by network administrators. This can be an effective method for networks with small and simple structures and reduce the effect of bandwidth and CPU resource consumption that occurs when other protocols are implemented. Example: [Huawei] ip route-static 30.1.1.0 Procedure: PC2 Ethernet 0/0/1 GE 0/0/3 LSW1 PC1 Ethernet 0/0/1 GE 0/0/2 Device AR1 AR2 PC1 PC2 PC3 PC4 GE 0/0/1 GE 0/0/1…While FTP employs a random port for data delivery, FTP servers continually listen on the same port for session clients. What is an FTP server's port number?
