...Linux Security Basics Security is always at the top of the list when setting up a network and also administering a network. Linux is an operating system that can be easily obtained over the internet due to its open source distributions. Linux is one of the most secure operating systems because of having less use than Windows for the end user. There are several security technologies in Linux that can be implemented into a network. The three technologies that I will be discussing are SELinux, chroot jail, and iptables. SELinux was developed by the National Security Administration in an effort to incorporate a strong, flexible mandatory access control architecture into the major subsystems of the Linux kernel. The NSA recognized that operating system security is critical at higher levels. It provides a tool to enforce the separation of information based on the confidentiality and integrity requirements. This helps when addressing threats of tampering and bypassing of application security. It also assists in the isolation of damage that is caused by malicious software or damaged applications. SELinux uses the Flux Advanced Security Kernel which contains components that provide support for enforcing many kinds of MAC policies like type enforcement, role-based access control, and multilevel security. The Linux kernel that is implementing SELinux enforces MAC policies that limit the user programs and system servers to only what they need to complete the job. When a limit...

...To perform a security plan, a full risk assessment has to be performed. This involves developing security policies and implementing controls to prevent computer risks from becoming reality. Risk assessment is a very important part of computer security planning. It provides a baseline for implementing security plans to protect assets against various threats that could occur in all of the seven domains of IT infrastructure. The User Domain is the weakest domain, therefore measure need to be taken to reduce the chance that user’s activity can bring down a system unknowingly or knowingly. A mandatory Computer Security training will need to be implemented in order to educate the users on the proper use of work computers. Train the users to use their machine properly and can effectively cut down on mistakes that can leave systems vulnerable to attacks. Also, there will be restriction to user’s ability to bring in and corrupt data using CDs, DVDs, and USB drives. Remote Access Domain, with the condition that the users are off sites, it is hard to know if their password has not been compromised. In cases where data is accessed without proper authorization, data should be completely encrypted to prevent sensitive materials from being presented to the open market. To prevent unauthorized people from logging onto the system, password delay and or denial after several tries should be implemented. Also, real time lock out should be implemented. Workstation Domain, the problem associated...

...IT302 7/9/2012 Research Linux Security Basics Linux, being one of the most secure operating systems in the world, has many features and services that enhance security to the maximum. Linux isn’t completely secure, like some people like to claim, but many distributions strive to make security a key feature. One of the greatest reasons Linux is more secure, is the simple fact of having a smaller user base than other operating systems; this means that Linux is a smaller target for most malicious intents. That doesn’t mean that distributions rely on this to secure their OS. There are many great and complex security features and services that come with Linux. One of the most complicated security features, I believe, is SELinux. Security Enhanced Linux is a security model developed by the NSA and provides a fine grained permissions system for files, users, groups, sockets, ports, and processes. SELinux was conceived because the current user level security system that Linux, and other operating systems, offer is insufficient for. To ensure a maximum security environment, SELinux uses the MAC security model. This means that an object only has the minimal set of permissions it requires to operate. SELinux uses sets of policies to handle permissions providing the system with a great level of security. These policies can be assigned as roles to users enabling specific rules and regulations for specific individuals. SELinux may be a powerful security feature, but it can also be a pain...

...Phoenix. AMI 6 Beeps: Keyboard controller / gate A20 failure The keyboard controller is a chip on the motherboard that communicates with your keyboard. It also controls the A20 gate that provides access to the high memory area (HMA). This component is indicating a failure. This is a problem with either the keyboard or the motherboard. Phoenix 1-3-4-1 Test 512 base address lines. Sometimes a memory stick can become loose causing the computer to be unable to read the memory or get errors as it's reading it. Try fixing this issue by opening the computer removing each of the memory sticks you have in the computer and then placing them back into the slots, reset the memory and restart the computer. If this doesn’t work replace the memory. Basic Security Hardware Network address translation: Every system on the Internet needs an IP address--like a phone number for computers--which is used to forge links with other systems across the network. NAT foils unauthorized connections by giving PCs behind the firewall a set of private addresses, while presenting to the world a single, public address. This switch makes it difficult for others to reach through...

...Identity theft is the crime of using someone else's personal information for self-gain. According to an article in USA Today, identity theft is surpassing traditional theft and is becoming the leading form of property crime (Anderson). The Federal Trade Commission estimates that more than 9 million individuals are victims of identity theft each year. The Justice Department puts the figure at more than 3.5 million households (Anderson). Anyone can become a victim of identity theft and it is not limited to the financial activities of one’s life. People’s identity is also stolen in order to commit criminal activities. Both activities are defined as fraud and are punishable by law if caught. Financial identity theft or fraud includes bank fraud, credit card fraud, computer and telecommunications fraud, social program fraud, tax refund fraud, and mail fraud. In fact, a total of 25 types of financial identity fraud are listed and investigated by the United States Secret Service (Obringer). In 1997, Secret Service agents made approximately 10,000 financial crime arrests which 94 percent involved identity theft (Obringer). Fifteen years later, Javelin Strategy & Research reports that over 12 million financial identity theft cases were reported (Javelin Strategy & Research). Other types of identity theft usually involve financial elements as well but are typically committed to fund some sort of criminal enterprise. Criminal activities include gaining...

...Lab 7: Security Basics Task 1: Procedure 1. An example of hardware firewall is Belkin, and an example of software is Norton 360. Task 2: Procedure 1. Almost all anti-virus programs offer some sort of trial period for first-time users. McAfee is the only one that I know for sure offers free protection. 2. A Trojan Horse is an email virus usually released by an email attachment. If opened, it will scour your hard drive for any personal and financial information such as your social security, account, and PIN numbers. Once it has collected your info, it is sent to a thief’s database. A malicious email message is one which had been deliberately crafted to cause problems on the server or on the client. Drive- by downloads are downloads which a person authorized but without understanding the consequences (e.g. downloads which install an unknown or counterfeit executable program, ActiveX component, or Java applet). .Any download that happens without a person's knowledge, often a computer virus, spyware, malware, or crime ware. Task 3: Procedure 1. Full backup is a complete backup of everything you want to backup. Differential backup software looks at which files have changed since you last did a full backup. Then creates copies of all the files that are different from the ones in the full backup. Incremental backup software creates copies of all the files, or parts of files that have changed since previous backups of any type (full, differential or incremental)...

...Leah Dolce ECO 103 Mortgage Project While doing this project, I kept finding myself to be very indecisive as to what I wanted in a home and what things would be important to me if I were to purchase one. This project helped me understand the basics of buying a home such as: where I would want my kids to go to school, how many bedrooms, how many bathrooms, property, neighborhood reputation, and much more. I had very little knowledge about most of the surrounding area so now I know what kind of research I would have to do to make sure I know exatcly what I want when purchasing a home. I did know I wanted it to be at least 3 bedrooms, 2 bathrooms, and have an updated kitchen. I was able to find those things in the home I selected but what I didn't realize was what the cost would be. There is a huge financial difference between a 15 year fix and a 30 year fix mortgage. For the home I selected it was a $522.76 difference in the monthly payment and a $91,271.79 difference in the amount of interest I would be paying for the life of the loan. If I was abel to afford such a hefty, monthly payment I would choose the 15 year mortgage because in the long run it would be cheaper. The lesson learned here, though, is find a more affordable house and make updates as you go along. All -in-all I had fun doing this project and it helped me understand the process into buying a home and gave me great internet resources to do...

...SYNOPSIS TITLE OF THE PROJECT HOSTEL MANAGEMENT SYSTEM PROBLEM STATEMENT This project needs to create the Hostel Management System (HMS) to organize the rooms, mess, student’s record and the other information about the students. All hostels without HMS are managed manually by the hostel office. And hence there is a lot of strain on the person who are running the hostel. This particular project deals with the problems on managing a hostel and avoids the problem which occur when carried manually. INTRODUCTION In hostels without a HMS all the things have to be done manually. The Registration form verification to the different data processing are done manually. Thus there are a lot of repetitions which can be easily avoided. Identification of the drawbacks of the existing system leads to the designing of computerized system that will be compatible to the existing system with the system which is more user friendly and more GUI oriented. We can improve the efficiency of the system, thus overcome the drawbacks of the existing system. Hostel management gives on idea about how the students details, room allocation, mess expenditure are maintained in the particular concern. The hostel management system also includes some special features like How many students can live in a room, and the students of the hostel can be recognized from their ID number. The administration has the unique identity for each members as well as students details. The stock management...

...nonstop work. Startups are a counterexample to the rule that haste makes waste. (Too much money seems to be as bad for startups as too much time, so we don't give them much money either.) A week before Demo Day, we have a dress rehearsal called Rehearsal Day. At other Y Combinator events we allow outside guests, but not at Rehearsal Day. No one except the other founders gets to see the rehearsals. The presentations on Rehearsal Day are often pretty rough. But this is to be expected. We try to pick founders who are good at building things, not ones who are slick presenters. Some of the founders are just out of college, or even still in it, and have never spoken to a group of people they didn't already know. So we concentrate on the basics. On Demo Day each startup will only get ten minutes, so we encourage them to focus on just two goals: (a) explain what you're doing, and (b) explain why users will want it. That might sound easy, but it's not when the speakers have no experience presenting, and they're explaining technical matters to an audience that's mostly...
