part of the public key infrastructure. These certificates helps the users to trust the website information confirming it is secure and a trusted party. CSR refers to Certificate Signing Request. Whenever a CSR is sent to the certificate authority, it is sent along with the public key and the other specific information possessed only by the owner. The CA then verifies the identity of the owner with the information provided by the owner. It then issues a certificate with the public key stating that the

the hub transport server will handle all flow of mail from within the company. All messages will be using SMTP to submit messages to the hub transport server. I have kept RPC encryption enabled for protection between my hub transport servers, mailbox servers, and my client access servers. But do to issues with RPC encryption and versions of outlook I am using Https between my client access server and the outlook web application. We have our second site that replicates with site 1 for redundancy

Unit-4 (ICS -305) Information security Information security (ISec) describes activities that relate to the protection of information and information infrastructure assets against the risks of loss, misuse, disclosure or damage. Standards that are available to assist organizations implement the appropriate programs and controls to mitigate these risks are for example BS7799/ISO 17799, Information Technology Infrastructure Library and COBIT. Information security management (ISM) describes

VPN Concepts A virtual private network (VPN) is used to transport data from a private network to another private network over a public network, such as the Internet, using encryption to keep the data confidential. In other words, a VPN is an encrypted connection between private networks over a public network, most often the Internet. VPNs provide the following services: Confidentiality: VPNs prevent anyone in the middle of the Internet from being able to read the data. The Internet is inherently

1. INTRODUCTION Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for commerce, security becomes a tremendously important issue to deal with. There are many aspects to security and many applications, ranging from secure commerce and payments to

message. Cryptography, then, not only protects data from theft or alteration, but can also be used for user authentication. There are, in general, three types of cryptographic schemes typically used to accomplish these goals: secret key (or symmetric) cryptography, public-key (or asymmetric) cryptography, and hash functions, each of which is described below. In all cases, the initial unencrypted data is referred to asplaintext. It is encrypted into ciphertext, which will in turn (usually) be decrypted

Week Four Individual Assignment Kevin M. Gattas University of Phoenix IS Concepts Richard Bohn Purpose The importance of the OSI (open systems interconnection) model is for networks to communicate within the system. It is a system formed to allow a network administrator to perform trouble shooting in a way that is logical and step by step within the OSI model Scope The purpose of this essay is to break down the seven layers of the OSI model. The seven layer model defines a standard

an attacker who can read the magnetic stripe: (1) store a cryptographic hash of the account number; (2) store the cipher text of the account number encrypted with the bank's public key using a public-key cryptosystem; (3) store the cipher text of the account number encrypted with the bank's secret key using a symmetric cryptosystem. Solution In each of these cases, the account number is assumed to be a secret. (1) This solution is not very secure, even though it is considered computationally difficult

community. These shows that an enterprise security service is a form of protecting the services or the product of individuals and groups in the community from harm (preventing unauthorized users from gaining access). Enterprise now uses Biometric, Encryption and some others forms of security to form the backbone of its services. The term "biometrics" is derived from the Greek words bio (life) and metric (to measure). Biometrics refers to the automatic identification of a person based on his/her physiological
