★ Has the ability to manage thousands of tasks at the same time ★ Allows multiple users to access the system simultaneously What is Linux? What is the Free Software Foundation/GNU? Which parts of the Linux operating system did each provide? Who else has helped build and refine this operating system? ★ Linux is an open source operating system based on UNIX.
4. The Free Software Foundation (FSF) is a non-profit organization founded by Richard Stallman on 4 October 1985 to support the free software movement, a movement which promotes the universal freedom to create, distribute and modify computer software. GNU developed many of the tools, including the C compiler that are part of the Linux operating system. Linux is the name of the operating system kernel developed by Linus Torvalds, which has since been expanded and improved by thousands of people on the Internet. Torvalds’s kernel and GNU’s tools work together as the Linux operating system.
Firewalls are good and help against websites that are illegitimate. It’s also good to have an antivirus on your computer to help protect against people who are trying to hack into your system. Perhaps someone is trying to gain access to your financial information; the antivirus stops them from getting in. Always make sure that when you are checking your e-mail and receive an e-mail with an attachment if you do not know who it is from do not open it. I don’t even open e-mails from people I don’t know whether it has an attachment or not.
Keep viruses and spyware off your system If you’re running Windows, you need to be running an anti-malware program to keep viruses and spyware off your system. Nothing will ruin good performance like a bunch of spyware. I use, Microsoft Security Essentials. It’s free and comes straight from Microsoft. 5.
The security weaknesses also make it possible to send malicious commands to the devices in order to crash or halt them, and to interfere with specific critical processes controlled by them, such as the opening and closing of valves. Thought to mainly spread by USB stick, or possibly by network shares, it cannot be defeated by simply turning off Windows autorun; simply viewing an infected file system will install the malware. A security specialist at Tofino believes that this zero-day attack, which affects all versions of Windows, may have been in the wild for a month or more. Preliminary assessments indicate that the malware does not appear designed to cripple infrastructure, but rather to steal information from SIMATIC WinCC / PCS7 implementations -- i.e., some form of industrial espionage. Of course that espionage could later be used to wreak havoc on these same or similarly configured systems (Underwood, 2010).
Linux OS is a derivative of the Unix OS. The Linux OS gain momentum through its progressive licensing which allow others to increase development with the OS. With overwhelming popularity from the creation of Linux OS, Unix OS reintroduce itself again. The functionality of both UNIX and Linux is very similar by both systems able to multitask, both systems are able to run on a variety of hardware platforms, and both are capable to use a command line. Linux is different through user friendly OS and by GUI.
This should not be connected to the main location but its own entity. If something goes wrong you are secure because you have a back-up copy of the data. • Virus Protection software- Trying to avoid getting a virus and training employees to watch out for signs of virus can be very important, especially through email. Try to avoid opening an email that does not look familiar or looks strange. In Conclusion It is important for an organization to be aware of the risk of technology.
IS3440 Linux Security Project 1 Task 2: Providing Open Source Server Solutions Recommended Open source software MySQL (Database) MySQL is the world's most popular open source database software. MySQL is an open source relational database management system. It is based on the structure query language (SQL), which is used for adding, removing, and modifying information in the database. Standard SQL commands, such as ADD, DROP, INSERT, and UPDATE can be used with MySQL. Apache Webserver (Web Server) Apache is the Internet's most popular Web server.
Many under developed countries are not enforcing the issues of copyright leading to outrageous software piracy. Let’s give ourselves a scenario: we love certain gadgets, software, and entertainment media. What should we do? They’re something we really want to have for fraction of the cost. Plus, we could buy them as gifts for friends and family.
Windows has a Virtual memory manager (VMM) and avoids allocating all the memory until it is absolutely necessary. Windows does prefetching, which is moving pages from the disk to the main memory before it is even needed. Pages that are not needed in the memory are stored into a system called Page file until further need. With the Linux operating system, the files are organized already into the hard drive. This will give speed to Linux and provide for faster
