Now that you are at the end of the course what are your thou

Now that you are at the end of the course, what are your thoughts about network security, and how have those thoughts changed during the past weeks? How does your experience with network security issues reflect on what you have learned? What more would you like to know about system security?

Solution

Net work security deals with security at different levels like,

at system level ( authentication,passwords , and other biometric aproaches)

network level ( fire walls to protect from intruduers)

to achieve network security we do the the following

shold not allow un athourised acess ( wired or wire less)

provide poerful protocol to establish net work

includes comminication, transmission,routing, and file transfer related.

The primary goal of network security are Confidentiality, Integrity, and Availability. T

experience with network security issues reflect on what we have learned

The following points provide some a lot of discussion on network security issues

As your server is that the main purpose for knowledge getting into and feat the network, you wish to be further cautiousregarding it. you would possibly ought to keep it updated and perpetually patched. Use a purported firewall that keeps hackersoff from your network.

Use a software package that makes log of all the activities on the network. Normally, your firewall provides you with the list of programs attempting to access external entities via the server.

you\'ll check these logs frequently to review if any program is behaving abnormally, thereby assessing if the server or any laptop on your network is suffering from malware.

The logs conjointlyfacilitate in crucial suspicious user activity.
The server (the main laptop just in case of peer to see networks) has to have powerful anti-malware. lots of free laptop security suites ar offered on the net. you\'ll choose one from them or select a paid security suite that contains anti-malware and a firewall.

As knowledge leaves your server to external destinations, folks could also be sniffing at the open ports to steal the information. to forestall knowledge larceny, use associate coding software package. SecureZip may be a smart program that enables you towrite and compress outgoing knowledge packets.
Check out the peripherals on your laptop. If you\'ve got printers, scanners and photocopiers on the network, confirm they\'re not accessible from net. to attain this, place them behind a firewall. you\'ll add them to the network as freelance elements rather thanconnecting them to the most laptop.

Some printers and photocopiers store knowledge to physical disks and so might get outknowledge if somebody accesses them through the net or otherwise. you must conjointly amendment the default passwords for these devices before plugging them to the network.
Make sure there\'s solely one entry and exit purpose for knowledge to travel through/fro your network. This conjointly meansdifferent users ought to be ready to connect with the net solely via the most laptop or server.

Network security is often at stake iffolks will connect with net directly from an area laptop.
Other than the server, you must even have anti-malware on every laptop on your network.

This makes positive that even thoughthe most laptop misses any malware, the opposite computers will catch it. it\'s higher to possess associate antivirus on networklaptops that is totally different from the one on the most computer or server. However, ne\'er install over one antivirus on an equivalent laptop as they\'ll produce conflicts leading to a laptop crash.
Create a user profile for every user of the network. This way, you\'ll avoid mistreatment the administrator account all the time. Use the admin account solely to troubleshoot, install or take away network elements and software package

. A parole of eight characters that contains a minimum of 2 digits and a special character makes it nearly not possible for hackers to interrupt it.
Always update the operational systems on all the computers of your network.

This helps in any reducing the vulnerabilitiesbecause the software developers establish and patch any weakness within the software.
Finally, educate the users of the network regarding attainable threats to the network and the way to cope with them. The coachingought to embrace lessons cherish scanning attachments before gap them and protection down the pc if a user intends to go away it for a moment.

Confidentiality confidentiality is to protect data from unauthorized users. Confidentiality part of network security makes sure that the data is available only to the allowed and authorized persons only

Integrity integrity is to maintaining the accuracy and consistency of data ,and to make sure that the data is reliable and is not changed by unauthorized persons.

Availability availability is the mechanism hich makes the network to make sure that the data, network resources/services are continuously available to the alloed users, whenever they require it.
