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,
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.
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?
Brandon Ward Multi-Layered Security Plan NT2580: Introduction to Information Security 2/22/2014 DeVon Carter One of the most susceptible assets to any company is its email system. Email is a critical communications tool for any business and is also a prime canal for malicious code. Emails, while in transit are in plain text, meaning anyone who has access to the network will be able to read any email sent, received and stored. Implementing a variety of security technologies will assist us in preventing such code from infecting our network. I would implement firewalls, cryptography, antispyware, antivirus, and content filtering.
1.) Each of the following is a reason why it is difficult to defend against today's attackers except: Complexity of attack tools. 2.) _______ensures that only authorized parties can view the information. Availability 3.)
Compression 4) Which of the following command-line parameters will prevent a program executed using Runas.exe from accessing the elevated user’s encrypted files? /noprofile 5) Which of the following actions can you NOT perform from the Win Firewall control panel? (choose all that apply): Allow program through firewall on all three profiles and Create Firewall exceptions based on Port numbers 6) Which of the following policy modifications would make it harder for intruders to penetrate user passwords by brute force attack? (choose all that apply): Increase value of Reset Account Logon Counter After and Enable Password Must Meet Complexity Requirements. 7) Connection security rules require that network traffic allowed through the firewall use
It utilizes a scanner to transmit the information as electronic signals. These electronic signals are transmitted to phone numbers linked with some type of printer. Fax machines use data networks. Pagers- are wireless communication devices that are designed to receive messages. Originally, the message transmitted to the recipient was the telephone number of the sender basically requesting a call back.
Computers are related to networks due to the fact that computers need to be able to communicate to one another on the same network. Computers come in different sizes and processing levels. Computers are needed in any wireless network. Price varies from $299.99 to $4,999.99 Tiger Direct (n.d.) A firewall is considered a device that connects or is built in the software and directly to a network or computer with Windows XP and higher operating systems. A firewall used security purpose that only allows trusted sources to access the network or the other way around.
SMS/Text Messaging – The SMS (Short Message Service) can be used in a variety of ways. A few examples include; cellular phones, GPRS systems, and web texting. SMS does not use any voice technology which is why it is sent over data networks. Fax Machines – Fax machines contain analog modems. This type of modem technology uses the voice network technology.
An analysis of the network systems in use The current network system that Patton-Fuller is using is a network that is One GB, using Cat 6 and single Mode Fiber which gives greater speeds and trusted reliability. The technologies that are in place also have an intelligence built into them that alerts the network operations center when any malicious intend to the system is being done. The network also has a build in redundancy to prevent collision. Patton-Fuller has been using a CISCO System 7609 Router and a CISCO Systems ASA 5510 VPN (Virtual Private Network) Router. This helps with secure VPN and Internet traffic through the ASA 5510 VPN Router.
