MITM is one of the most dreadful network threats. An intruder here establishes an independent connection with both sender and receiver, intercepts their messages one by one, modifies those messages and relays them back to the sender and receiver.
This all occurs so smoothly that both the sender and receiver never come to know that they are being overheard by someone. In addition, it exposes your network to several other threats. A brute Force attack is performed to guess the maximum combination of passwords. The attacker checks all passphrases and passwords until a correct match is not found.
Browser attack is intended to expose sensitive information like a credit card, login details, and other details. When a browser is compromised, the attackers gain access end-user system. Attackers can infiltrate the network by hijacking the browser and spread malicious code to steal the information.
Browser attack includes social engineering attack, buffer overflow, XSS attack, man-in-the-browser attack. SSL creates a protected tunnel using strong authentication for data transmission between the client and a server. The attacker uses an unencrypted session to attack flowing plain text data. To prevent SSL attacks, network testing is performed and shielded from upcoming attacks.
Attackers sniff a plain text communication between the client and DNS servers. PGP then creates a session key, which is a one-time-only secret key. This key is a random number generated from the random movements of your mouse and the keystrokes you type. This session key works with a very secure, fast conventional encryption algorithm to encrypt the plaintext; the result is ciphertext.
This public key-encrypted session key is transmitted along with the ciphertext to the recipient. The speed of current computer cannot do so, but no guarantee for our future computers. It is a matter of time. Hackers and data theft treat security system as challenge instead of obstacles.
The security threat is still on. Network Security Despite the perfection of available encryption system we have, if our network itself is not secured. All encrypted transmission will be a wasting of time. Imagine a man stand behind you watching you entering pin number in an ATM machine; the security system cannot actually help you from protecting your pin number.
This applies to your network also. All your confidential information is stored in your network. If people break into your network, they get far more information than just sniffing emails and transmitting data. Therefore, enhancing network security is equally vital to security. Hackers, come in many varieties. Online shopping and Electronic Exchange for online casinos where millions of personal information and credit card information stored.
Web mail database stored millions of login names, email information and email addresses. China, turning from oil self-sufficiency to the world's second largest oil consuming countries, is now faced with a huge demand gap…. Internet Security Many people today are familiar with the Internet and its use. A large number of its users however, are not aware of the security problems they face when using the Internet. Most users feel they are anonymous when on-line, yet in actuality they are not.
There are some very easy ways to protect the user from future problems. The Internet has brought many advantages to its users but has also created some major problems. Most people believe that they are anonymous when they…. Internet Security. How safe is your computer? The Internet is a very powerful tool that we use to navigate and communicate with the rest of the world.
If you have access to a computer and a modem, you are licensed to drive on the information superhighway. And you are one of a growing number of online participants. The Internet offers many benefits. Web sites provide a vast world of information, entertainment….
Internet privacy may be a thing in the past due to necessary government control. Executive Summary: The NSC has tasked us to assess the potential risks associated with the United States government expanding their abilities of….
