Network Security And it's Importance

 

1.what is the importance of security on computer network?

Network security is any action an organization takes to prevent malicious use, malfunction, modification, destruction, improper disclosure  or accidental damage to the network’s private data, its users, or their devices. The goal of network security is to keep the network running and safe for all legitimate users  and allows computers, users and programs to perform their permitted critical functions within a secure environment.

 

Importance :-

Network security is important for home networks as well as in the business world. Most homes with high-speed internet connections have one or more wireless routers, which could be exploited if not properly secured.  A solid network security system helps reduce the risk of data loss, theft and sabotage. Except that, some of the more importance of network security are as follow :

  • ·      Network security is any activity designed to protect the usability and integrity of your network and data which includes both hardware and software technologies.
  • ·      It targets a variety of threats.
  • ·      It stops them from entering or spreading on your network.
  • ·      Effective network security manages access to the network

  • ·      Network security helps protect our workstations from harmful spyware. It also ensures that the shared data is kept secure.
  • ·      Network security promotes reliability of your network by preventing lagging and downtimes through continuous monitoring of any suspicious transaction that can sabotage the system.
  • ·      Competent network security procedures keep data secure and block vulnerable systems from outside interference. This allows the network’s users to remain safe and focus on achieving the organization’s goals.

Waterfall Model (Theory)

1.    Compare Waterfall Model vs. V Model (Difference & Similarities) Waterfall Model The waterfall model is a breakdown of project activities into linear sequential phases, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. It is also called a classical model used in system development life cycle to create a system with a linear and sequential approach. It is termed as waterfall because the model develops systematically from one phase to another in a downward way. All these phases are cascaded to each other in which progress is seen as flowing steadily downwards (like a waterfall) through the phases. The next phase is started only after the defined set of goals are achieved for previous phase and it is signed off, so the name "Waterfall Model". Let’s take a look at an example of a software engineering project plan using a waterfall model. In this example, we’ve scoped out tasks for adding a new app feature.

Dynamic NAT vs Static NAT

Image
Static and Dynamic NAT Both static and dynamic NAT requires that enough public addresses are available to satisfy the total number of simultaneous user sessions. Static NAT Static NAT also called inbound mapping, is the process of mapping an unregistered  IP address  to a registered IP address on a one-to-one basis. The unregistered or mapped IP address is assigned with the same registered IP address each time the request comes through.  This process is particularly useful for web servers or hosts that must have a consistent address that is accessible from the Internet. Simply, Static NAT enables a PC on a stub domain to maintain an assigned IP address when communicating with other devices outside its network or the Internet. Static NAT configuration commands example: R1# config t R1(config)# ip nat inside source static 10.10.10.2 212.165.200.123 R1(config)# interface fa0/0 10.10.10.1 255.255.255.0 R1(config)# ip nat inside R1(config)# interface se0/0 192.168.1.1 255.255.255.0 R1(confi
