Which of the following account lockout policy modifications could you make to ensure that user passwords cannot be intercepted by analyzing captured packets? (D) Disable the Store Passwords Using Reversible Encryption policy 2. Which of the following mechanisms is most often used in firewall rules to allow traffic on to the network? (D) Port numbers 3. Which of the following NTFS features is incompatible with EFS encryption?
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,
Wired equivalent privacy 12.) What is data called that is to be encrypted by inputting into an encryption algorithm? Plaintext 13.) A mathematical value used to produce ciphertext is called a(n)_______. Key 14.)
By not relying on a specific algorithm, it allows the suite to be modified in the future to support even more security methods. It operates at the network layer, encrypting IP packets making them confidential so that only the receiving device can accept and read them. In addition, it uses checksums to see if the data packet has been manipulated during transfer. IPsec uses Internet Key Exchange to ensure authentication with usernames, passwords, pre shared keys and digital certificates For IPsec, AES is considered the best form of encryption available. It uses a 128 bit shared secret key to decrypt and encrypt data being sent through the VPN.

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.

It does not guarantee data integrity and discard packets when there is network congestion. In reality, it still delivers data with high reliability. Frame relay uses DLCI in order to communicate frames from one side of the network to the other, the DLCI should be unique for each path on the network, so that when a frame is sent to a certain location and the DCLI is attached it can be sent to the correct recipient. The DLC looks like the
