SPAP encrypts the password and then sends it and the username across the network (Shinder, 2014). CHAP and MS-CHAP is another remote access authorization protocol. CHAP uses a hash algorithm to hash the password so the hashed password could not be reverse engineered to retrieve the original password, but it is vulnerable to impersonation by remote servers. MS-CHAP is not because of the two-way authentication verifies both the client and the server identity. MS-CHAP added an individual cryptographic key increasing its security for the transmitting and receiving of information (Shinder,
What other test could you perform to prove that it was your computer’s firewall that was blocking the connection and not the firewall on the computer you are using as a client? Try to access other web sites from the host computer 9. Why can you not simply leave Windows Firewall turned off when you deploy an actual web server? That would leave your computer open to a cyber-attack Exercise 5.3 10. Why are you now able to continue to the web site from the client?
The extent to which the user does not notice that a file is encrypted. BitLocker – a system in window vista by which entire hard drive volumes can be encrypted Trusted Platform Module (TPM) – hardware component used to store cryptographic information, such as encryption keys, and to perform other security duties Certificate autoenrollment – feature of windows server 2003, enterprise edition that automatically uses the existing certificate to sign a renewal request for a new certificate before the existing certificate
11. a. Restrict access by IP address. 12. d. Exchange Server 2003 will not install until you have disabled and removed the Windows Server 2003 POP3

Port scan is as the name implies, a scan of the open ports on each computer of the network to define which ports are open and what services are running on them. This information can be used to set up an attack on the network by allowing the hacker to bypass vulnerability in the software being run or on any open ports that can be used to gain deeper access to the network. With a port scan the probe sends information to each port on the network and the open ones respond back, this data can be used to determine the easiest way to infiltrate the network. The safest way to defend against this type of probe is using a firewall. Just as in a ping sweep, if you deny access to a port scan requesting information from the network you render them
I) Special Identity- placeholder for a collection of users with similar characteristics 5. C) Authentication- confirmation of a user’s identity 6. H) Elevation Prompt- displayed when an administrator requires administrative access 7. J) Mandatory User Profile- a profile that multiple users can run simultaneously 8. D) Secure Desktop- suppresses the operation of all controls except the UAC prompt 9.
Is there a firewall configured on your computer, is your firewall block ing ports, if you turn off the firewall does it resolve your problem? If not move onto the Network Layer; can you ping your default gateway, are your IP settings correct, can you trace a well-known IP/DNS address/URL, and finally has your network adaptor b een assigned an APIPA address? You then move to the data link layer. Is the light lit on your network interface card, is your NIC inserted/installed correctly, is the NIC d isabled in the device 4.4 review 1. The divide-and-conquer
Cryptography is a way for us to encrypt data from hard drives, emails, when data is traversing networks and data between web browsers and web servers. Utilizing symmetric key encryption will allow for secure data to be transmitted with an exception, the data must traverse a secured network channel. This can be accomplished with the utilization of a VPN or virtual private network. I would recommend using a SSL VPN system or Secure Sockets Layer. These provide a high level of security and are known as a clientless method.
