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?
I can assume that my organization MIS department will do it for me because they would identify issues and problems and promote to employees how to protect their assets that might be vulnerable to theft in the outside world. It’s important to protecting our assets that might be on portable devices to prevent the theft, use two factor authentications, and encrypt your data. Protecting your privacy by using strong passwords, adjusting the privacy settings on your computer, and surf the web anonymously. Other ways to protecting your privacy may include e-mail anonymously by reporting spam to your email provider and knowing what information on your emal is creditable, and by erasing your Google search history to prevent important history from being discovered. | 2.
This helps with secure VPN and Internet traffic through the ASA 5510 VPN Router. The VPN is able to locate in a specific area where the malicious attack is coming from and which employee has done it. There is remote access to the Patton-Fuller network but it is secure and only personal that has been authorized accesses it.
Case Study Week 1 Katherine Vega DeVry University SEC 280 Ahmed Azam November 4, 2012 Ping Sweeps and Port scans are related programs or tools, called network probes, which allows a person to not only gain access to online computers, but also to determine what services are being run on them furthermore to get an edge on compromising information. This network probes aren’t inherently malicious on their own as they are used by network administrators for the aforementioned diagnostics, however in the wrong hands they could pose a security threat. This is not meant to cause fear but to bring about awareness to computer users. As the programs are most commonly used for network diagnostic and determining other network problems. To begin
LAB 1-4 Questions 1. What is the current screen resolution? 1366 x 768 2. What security advantages does displaying the login screen on resume offer? It offers security from anyone one trying to gain access to your computer.
Unit 3, Assignment 1 Anthony Correll January 16, 2015 NT2580 Remote access security policy involves the policies and conditions that are in place that allow users to connect to servers when out of the network. In the case of Richman industries, they are interested in maintaining connections with their users, and sharing app data that is on a server for their day to day operations. In their case, I would have access policy that is based on Explicit Allow policies. This means that the policy grants “Permission” to access the servers remotely if the connection attempt matches the policy conditions. Some of the requirements would include strict control enforced via one-time password authentication or public keys with strong pass-phrases.
Matching 1) Multi-factor authentication uses : Passwords plus smartcards 2) These are potentially destructive software: Malware 3) Automated password guessing is known as : Brute force 4) What is the standard for smart card support : PIV 5) Decrypts data encrypted with a certificate: Private Key 6) Standard for fingerprint scanners and other devices: Windows Biometric Framework 7) Windows authorization mechanism: User rights 8) What firewall rule requires IPsec: Authenticated exception 9) This key is stored in a digital certificate: Public key 10) Firewall exceptions are called: Rules Multiple Choice 1) Which of the following account lockout policy modifications could you make to ensure that user passwords cannot be intercepted by analyzing captured packets? 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? Port Numbers 3) Which of the following NTFS features is incompatible with EFS encryption? 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?
Under the USA PATRIOT Act, what legal documents are needed for law enforcement to obtain information regarding temporarily assigned network addresses or billing records from Internet service providers? The legal documents that are needed for law enforcement to obtain information are called subpoenas 4. What types of information might a law enforcement officer want to acquire when preparing for the execution of a search warrant for a computer? Prior to executing the search warrant the law enforcer must have a proper plan in place. Officers should gather intelligence and conduct surveillance.
It would be highly suggested that each user to have secure passwords as part of their login details in order to enhance the security of the environment further. The Wireless portion of the network is possibly the greatest area of potential security concern This needs to be secured so that no open network is presented to anyone within range of the Access Point. A combination of disabling the broadcast of the SSID (Wireless Network Name) with WPA-2 Encryption will create the desired level of security. An additional possibility would be to only allow certain devices to connect to the Wireless Network by restricting them in accordance with their MAC (Physical Network) Address. Finally, if we extend security to include the security of the business data then adequate backup mechanisms and redundancy/ resiliency measures need to be in place.
