Computer Network Security

critical information

To be shared only with those who have a need to know.

If you are communicating to a secure website via https (port 443) then the communications are encrypted by default. The use of https means a secure communication to another web server.

The only way to ensure confidentiality (security) in the data transmission is to encrypt it. Since you don't know which public access lines or networks the data packet will travel through, without encryption anyone could read the information. To make that not possible, encryption is used in the data transmission.

The first step to building a network is to build a plan. Knowing what you want and how one plans to achieve it helps a lot. Thinking outside the box helps.

For a security administrator it can be helpful in giving a better understanding of the principals involved in hacks themselves. It goes through and focuses in phones with explanations of key components from building your own blue box to central office operations.

BitLocker is a helpful tool which can simultaneously block or encrypt most of your computer's file system while the user performs on or offline work. As a powerful and versatile program, it appears to be gaining acceptance on websites like Microsoft and Dell.

Yes, especially if you don't encrypt your communications. Packet sniffer programs do this all the time.

Some indicators of a phishing attempt would be formatting or spelling errors in an email, an email sent by a company with which you do not have an account, and if the email tells you need to update your account or provide other information.

Ask Professor Kuroski.......lol...

many many websites get hacked but the most common one for teenagers is myspace facebook and other websites like that

for internet cable it is called RJ11 and for the intranet cable it is called RJ45

These are the terms of IP Confidentiality mean no one can see your private data while it traveling through the networks some hashing technologies are like SHA (secure hashing algorithm)

Integrity also the term of IP SEC . no one can change your data while data is traveling...some techniques are also utilized for this..like make a magazines etc

Availability..high availability of data for this purpose use SAN or NAS

With SSL your traffic is being encrypted and cannot be understood or altered by a man in the middle attack or brute force unless the keys used are weak (which is not likely).

There are ways to fake connections (primarily by proxy servers) so that the user believes they have an SSL connection to a site but they really do not. The actual SSL connection is from the proxy server to the site, not the user to the site. The end result is that the proxy may be able to read the user's information.

Today more than ever, network security is more vital than ever. Finding a company that provide these services could be researched in the local area or searching on line for a company providing these services. One could also get recommendations from other companies in the local area.

A network threat is a security breach within a computer system. Examples off this is Denial-of-Service, Unauthorized Access or Confidentiality Breaches.

This is a technique you can do if you have the authority to do that. This is usually done via MSUS and other tools in large corporations to push applications to the desktop.

Blocks ports and Protocols
block ports

1. It is computationally easy for a party B to generate a pair(Public key KUb, Private

key KRb)

2. It is computationally easy for a sender A, knowing the public key and the message

to be encrypted , M, to generate the corresponding ciphertext:

C=EKUb(M)

3. It is computationally easy for the receiver B to decrypt the resulting ciphertext

using the private key to recover the original message :

M=DKRb(C)=DKRb[EKUb(M)]

4. It is computationally infeasible for an opponent , knowing the public key,KUb,to

determine the private key,KRb.

5. It is computationally infeasible for an opponent , knowing the public key,KUb,

and a ciphertext, C, to recover the original message,M.

6. The encryption and decryption functions can be applied in either order:

M=EKUb[DKRb(M)]=DKUb [EKRb(M)]

I conclude my seminar saying that as hackers and many algorithms are there to break passwords and much valuable information, which leads to a great loss. Hence network security provides the remedy by many ways. Hence much more advanced security measures would be more helpful. So always that should be an eye on network security as it is much and more important.

Wireless is typically less secure because it uses radio waves for transmission. In other words, you have your data "floating" in airspace which makes it more susceptible to being compromised (hacked). With a wired connection someone cannot "steal" your data frames (packets) unless they physically connect to the network cabling. Additionally, the level of security built into wireless technology is less advanced than that of wired networks. This is mainly due to the fact that 802.11 is a relatively newer protocol standard. Manufacturers (both hardware and software) are developing better security for wireless systems and it is possible to harden the security of a WLAN by using the current security protocols along with using some third-party software. For additional specific information read the RFC standards for 802.11.

Hello Deakin Sudent,

Please dont cheat
