...2. Cryptography: Overview An overview of the main goals behind using cryptography will be discussed in this section along with the common terms used in this field. Cryptography is usually referred to as "the study of secret", while nowadays is most attached to the definition of encryption. Encryption is the process of converting plain text "unhidden" to a cryptic text "hidden" to secure it against data thieves. This process has another part where cryptic text needs to be decrypted on the other end to be understood. Fig.1 shows the simple flow of commonly used encryption algorithms. Fig.1 Encryption-Decryption Flow As defined in RFC 2828 [RFC2828], cryptographic system is "a set of cryptographic algorithms together with the key management processes that support use of the algorithms in some application context." This definition defines the whole mechanism that provides the necessary level of security comprised of network protocols and data encryption algorithms. 2.1 Cryptography Goals This section explains the five main goals behind using Cryptography. Every security system must provide a bundle of security functions that can assure the secrecy of the system. These functions are usually referred to as the goals of the security system. These goals can be listed under the following five main categories[Earle2005]: Authentication: This means that before sending and receiving data using the system, the receiver and sender identity should be verified...

...Answer the following questions a) What is the basic concept of interest? b) How is interest usually expressed? (In terms of the principal) Interested is usually expressed as a percent on the principal. c) What does the interest rate multiply on for simple interest? A 30-year loan for $100,000 with a rate of 6%. The monthly payment would be $599.56 for both the standard and simple interest mortgages. The interest due is calculated differently, however. On the standard mortgage, the 6% is divided by 12, converting it to a monthly rate of .5%. The monthly rate is multiplied by the loan balance at the end of the preceding month to obtain the interest due for the month. In the first month, it is $500. d) What does the interest rate multiply on for compound interest? It multiplies interest* total amount What is the formula for simple interest? I=P *r* t e) Example below f) What is the formula for compound interest? P is the principal (the initial amount you borrow or deposit) r is the annual rate of interest (percentage) n is the number of years the amount is deposited or borrowed for. A is the amount of money accumulated after n years, including interest. When the interest is compounded once a year: A=P(1+r)n*t Also you can use compound interest like this Annually = P × (1 + r) = (annual compounding) Quarterly = P (1 + r/4)4 = (quarterly compounding) Monthly = P (1 + r/12)12 = (monthly compounding) Given the following...

...Richman Investments To: Don, IT supervisor From: XXXX,XXXXXXXXXX, IT Intern I was tasked with drafting a report on the Richman Investments “Internal Use Only” data classification standard. This report will address which IT Infrastructure domains are affected by the standard and in addition how they are affected. There are seven layers (domains) in the IT Infrastructure that are affected by this; however I will mainly focus on three. User Domain is the first layer in the IT Infrastructure and is the weakest link in an IT Infrastructure. This is where you will encounter your Risks, Threats and Vulnerabilities. But you can also mitigate most of the common User Security risks. Here, the employees can access systems, applications and data based on their access rights. This is where one will find an Acceptable Use Policy (AUP). The AUP defines what every system user is allowed to do with company owned systems. Workstation Domain is the second layer in the IT Infrastructure. This is where most users connect to the IT Infrastructure. Keep in mind, a workstation can be either a centralized desktop computer or a laptop computer or any device utilized to connect onto the network. The users will initially access systems, application and or data. However, in order to protect the systems, workstations require additional layers of security such as; logon IDs and passwords. LAN Domain is the third layer in the IT Infrastructure. Your LAN (Local Area Network) allows for computers...

...Internet DMZ Equipment Policy 1.0 Purpose The purpose of this policy is to define standards to be met by all equipment owned and/or operated by Richman Investments located outside Richman Investment's corporate Internet firewalls. These standards are designed to minimize the potential exposure to Richman Investment from the loss of sensitive or company confidential data, intellectual property, damage to public image etc., which may follow from unauthorized use of Richman Investment resources. Devices that are Internet facing and outside the Richman Investment firewall are considered part of the "de-militarized zone" (DMZ) and are subject to this policy. These devices (network and host) are particularly vulnerable to attack from the Internet since they reside outside the corporate firewalls. The policy defines the following standards: * Ownership responsibility * Secure configuration requirements * Operational requirements * Change control requirement 2.0 Scope All equipment or devices deployed in a DMZ owned and/or operated by Richman Investment (including hosts, routers, switches, etc.) and/or registered in any Domain Name System (DNS) domain owned by Richman Investment, must follow this policy. This policy also covers any host device outsourced or hosted at external/third-party service providers, if that equipment resides in the "RichmanInvestment.com" domain or appears to be owned by Richman Investment.

...Multi-Layered Security Outline To: Richman Investments Senior Management Outline includes: Security solutions for each of the seven domains. User Domain: This is where the first layer of defense starts for a layered security strategy. We will conduct security awareness training, restrict access for users to specific systems and programs, create an acceptable use policy, and track and monitor employee behaviors. Workstation Domain: Start by creating strong passwords to protect workstation access, then enable antivirus protections, and mandate security awareness training to all employees. This domain is almost as vulnerable as the user domain and also needs constant monitoring. LAN Domain: To prevent unauthorized access we can physically secure wiring closets and data centers, implement encryption protection, define strong access control policies and strong second-level authentications. LAN-to-WAN Domain: Disable ping, probing and port scanning, apply strict security monitoring controls, and update devices with security fixes and software patches right away are excellent measures to take. WAN Domain: Use encryption and VPN tunnels for end-to-end secure IP communications, and scan all e-mail attachments for type, antivirus, and malicious software. Back up and store data in off-site data vaults. Remote Access Domain: Establish user ID and password policies requiring periodic changes, set automatic blocking for attempted logon retries, and encrypt all data within the...

...Richman Investments’ Remote Access Security Standard defines required tools and practices to ensure that faculty and staff can access data from remote locations in a secure manner. Company data, which is fully defined in the Information Security Standard, can generally be grouped into three, broad categories: 1. Confidential Data: This category includes the most sensitive data (ex: Social Security numbers) and requires special protection. 2. Enterprise Data: This category also includes sensitive information (ex: business records) that must be protected. 3. Public Data: This information is generally widely disseminated and can be accessed with higher levels of security protection. Different security requirements apply to each of the categories of data. The objective of the company’s security standards is to keep company data on internal, secure systems whenever possible and apply high levels of security in the rare cases when sensitive data must be moved out of internal systems. Level 1 Minimum Computer Security Requirements: The requirements below apply to all computers that are used to access company data from remote locations. Faculty and staff who only need to meet these minimum requirements include those who only need SU “public” services. Such services include www.syr.edu and other public web sites, Myslice “self service” functions, Outlook/Exchange e-mail, and departmental Terminal Servers, among others.

...IT-255 Part 1 Multi-Layer Security Outline Task at hand: Richman Investments Network Division has been handed the task of creating a general solutions outline for safety of data and information that belongs to their organization. This following outline will cover the security solutions of the seven domains that the IT infrastructure is made of. User Domain | The User Domain being the weakest link of the seven layers. This is from lack of users not aware of security policies and procedures. | To secure this link to its fullest. The employees should be trained and updated with security policies and procedures. The system should have firewall and antivirus software installed as well. | Workstation Domain | The Workstation Domain can be made up of desktops, laptops, iPods and or personal assisting tools like Smartphone’s. | The common threat to the Workstation is the unauthorized access to the system. The solution would be to enable password protection and automatic lockout during time of inactivity. | LAN Domain | LAN being a collection of computers connected to each other. The links can use several tools direct connected with a switch and wireless with a router being the most common. | Unauthorized access can tap into and work its way into workstations, data centers (servers). To put a block and set-up counter measures a Firewall and OS Security Software installed and monitored. | LAN-TO-WAN Domain | LAN-to-WAN is where the IT infrastructure links to a wide...
