Cisco Switch Configuration

All user-chosen passwords should be complex in nature (e.g., containing mixed case and two non-alphabetic characters. Non-alphabetic characters include numbers (0-9) and punctuation. The use of control characters and other non-printing characters is discouraged because they may inadvertently cause network transmission problems.

Encryption technique is the translation of data into a secret code that will prevent hackers or identity thieves from being able to break or read the data that is sent across the network.

* If passwords are written down, they must be kept in a safe place, e.g. a wallet, or a safe. Passwords are not be be written down and tape to the bottom of the keyboard, stuck to the computer monitor with a sticky note, or put in an unlocked desk drawer.

shown in Table 2. It indicates that all the default alphabet password which is "jackson" can be

When a fellow general received the message, he would wrap the paper around his corresponding scytale to decipher the message (Tyson 2014). Since the advent of computers though, encryption has become increasing important and relies almost solely on cryptographic means to secure information. When speaking about encryption today, it refers more to the process rather than the mathematical formulas used to scramble data. The basic idea behind encrypting a computer message is such that it is scrambled with a sequence of random bits, known as a key, and only parties with the corresponding key can transpose it back into a comprehensible format. These keys are created via a cipher, otherwise known as an algorithm. When a user sends a message, known as the plaintext, across a network, the computer applies an algorithm to the information to encode it, resulting in a ciphertext (Encryption Basics 2014). This method can be best summarized visually:

Notice that the commands that you entered to establish passwords for the various modes of access are now password protected and that you can read the passwords. (1 point)

When the open button is pressed, a command-line interface will be displayed; which ends the GUI interface of PuTTY. From there you’re able to setup iptables, install various packages and change the root password.

In this case, the encryption password is unique to the Windows account encrypting the file. In this case, it also happens to be “Pa$$word.” Here is a screenshot showing the file post-encryption.

On the configuration page , enter a name in the VPC name field. For example, enter the name of the VPC and the name of the subnet, so that the user can recognize the VPC and subnet in the Amazon VPC console after it is created.

Policy Enforcement:- How to apply the password policy can be configured separately for each SQL Server connection. Use ALTER LOGIN to determine the password policy option for the SQL Server access.

3. Based on the information in the main Server Manager display, what roles are currently installed on the computer?

Refer to Figure 5-2. What will the host name of your router be? lab-a 2. Which interfaces is your router using? F0/0, F0/1, and S0/3/0 3. What are the IP addresses and subnet masks for those interfaces? 192.5.5.1 and 255.255.255.0, 205.7.5.1 and 255.255.255.0, 201.100.11.1 and 255.255.255.0 4. What is the enable secret password? class 5. What is the enable password? cisco 6. What is the VTY password? cisco 15. There is another way to access the initial configuration dialog other than being prompted for it automatically as a consequence of having erased the contents of NVRAM. You can use the setup command at the privileged EXEC mode prompt. Press Enter if necessary to reach the user EXEC mode prompt. What does this prompt look like? Greater than symbol (>) 16. Type enable and press Enter to access privileged EXEC mode, which is also known as enable mode. You should be prompted for the enable secret password you configured in the system configuration dialog. How do you know you are being prompted for the enable secret password and not the enable password? Because the secret password was set during the initial setup process 17. Type class and press Enter. How did the prompt change? lab-a> to lab-a#

One of the most important security considerations is how remote clients will be authenticated. PAP (password authentication protocol) will be used. Individuals who remotely access the network will do so by using company issued devices. They are to use the same security considerations they would be subject to at their on-site workstations. Remote access servers will use encryption methods and be closely monitored.

The purpose of this paper is to provide a better understanding of switching and routing used in a network environment and familiarize the reader with various hardware and software associated with there functions. This paper will look at some switching concepts that will include store and forward switching, cut through switching, fragment free switching, and V-Lan. This paper will also cover routing concepts, along with some comparisons including routed vs. routing protocols, Classful vs. classless protocols, and distance vector vs. link state protocols.

The first method, the computer is to use DES with a password as a key to encrypt plain text. In this case the attacker will have both ciphertext and the plain text though the physical security is difficult to maintain. This key cannot be further used for the decryption process. So with these mentioned limitations, we DES has strong encryption method which is always difficult for the attacker to break.
