This unique characters, otherwise called signatures can be a byte pattern in the virus. This is usually done using the AV software, the AV software uses the signature obtained from the signature database to detect the malware, and when a match is gotten, the AV software then alerts and prompts the user to repair or remove the file.
With widespread use of internet services, the network scale is expanding on daily basis and as the network scale increases so will the scale of security threats which can be applied to system connected to the network. Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders. External intruders are individuals who are not authorized to access the system and attack it using various techniques. Internal intruders are individuals who are authorized to access the system but perform unauthorized activities on the system. An IDS watches activities performed on the network and searches for malicious
I have been asked to use Ubuntu? One comparison between windows and linux is that Linux is a lot freer than windows because windows are restricted. Another comparison is windows are a lot safer because if something breaks you get paid support whereas on Linux you do not have any support. My experience with Linux is not much as I am entirely a windows user.
The primary purpose of this lab was to get familiar with RLES and establish a base infrastructure. This infrastructure includes a router/firewall and Linux server for network monitoring and documentation. Network monitoring is crucial in any infrastructure, no matter how small or how large. Without it, there is no way to know a system has gone down until users start complaining. With it, the system/network administrator can be aware of the issue the instant it happens. Documentation is also extremely important in any environment. Documentation is an Administrator’s lifeline if a system breaks and they either need to recreate it or repair it.
After compiling all of the ingredients into a numbered list, I find out that every product “purchased” at Harris Teeter would account for $116.19 over the budget. The few adjustments I made to my shopping list beforehand did not help reduce the total to a reasonable price either. While I was going through all of the products at home, I crossed out a few unnecessary items that were optional or switched to products with a lower price just to see if I could be within the budget. Eventually, after I was done “shopping” and tallying up all of the prices, the cost still exceeded the price that I calculated in my head. As I went down the aisles searching for foods on my grocery list, I kept a close eye out for products that had nutritious labels such as organic, fresh, or low in sodium so that the college student I chose could receive the right amount of nutrients needed for a healthy lifestyle. As a result of that, I realized that most of the nutritious products were set at
This lab has many different overall goals that are meant to introduce us to the challenges and procedures of building a preliminary enterprise environment from the ground up. Each task has it’s own set of goals that expose us to important areas of system administration in this type of environment. The lab first introduces us to installation and configuration of an edge routing device meant to handle all internal network traffic between devices, and allow access out to an external network, in our case the Internet. The lab then introduces installation of an enterprise Linux distribution, Red Hat Enterprise Linux 7, which will be used as the main Linux based server in our enterprise environment. We are then introduced to installation of a Wiki
I definitely feel that Linux and Windows machines provide very different sets of traits that work better for different things. Linux is clearly the more easily secured server as it allows a lot more granular control of every piece of the operating system and the data that is housed there. Also, being completely open source, it allows for a lot more options for software as well as control over every aspect of the system.
This stage involves translating the requirements from the previous stage into detailed designs that address them. This detailed design should be easily converted to programming logic. It is at this stage the technology specifications for implementing the solution, logical structure of the application, design of WebPages, database designs etc are finalized. Test plans and test cases for the application are devised at this stage.
Using the formula Future value = Present value * exp(rt) I can calculate the future value for the population of the state Georgia. 27.821 million= 10.235 million * exp (0.1*10) is the formula to calculate the future value of Georgia using a rate of growth of 10% and a time of 10 years. 55.643 million= 10.235 million * exp (0.1*20) is the value if the time changed to 20 years. 83.464 million= 10.235 million * exp (0.1*30) is the future value of population at 30 years. 33.385 million =10.235 million * exp (0.12*10) is the value of the of the population when the rate changes by an increase of 2%. 38.950 million =10.235 million * exp (0.14*10) is valuation of the future population when the rate increases by 4% from its original rate of 10% for a total rate of 14%. Each input is accurate in comparison with its Excel counterpart, however, the Word calculations will have greater precision due to the estimation of the of the Excel counterparts.
1. Describe the functions of the kernel, service, and command layers of an OS. The kernel basically acts as the interface between hardware and applications. The kernel is also known as the engine or core of an OS, the outermost part of an operating system that interacts with user commands. Some of the kernel’s tasks are resource allocation, process management, memory management, input/output device management, and security management. It basically mediates access to system resources. The kernel is the vital center of a computer operating system. The service layer acts as a source to resources for application programs such as folder manipulation, input/output device access, starting/stopping programs, and creating, moving, and resizing GUI windows.
SmartScreen Filter in Internet explorer 8 has multiple mechanisms for observing sketchy websites. One of these is to analyze web pages for different phrases and patterns that would represent a phishing attempt. This does not use any more bandwidth usage and can be used on company workstations. Other parts of SSF (SmartScreen Filter) performs online lookups of various sites and down sites using a database that Microsoft controls. This although involves more bandwidth. (And can not be used for this answer.)
In the event of physical thefts of company equipment or other network property we have to secure vulnerabilities in company property access and perimeter physical barrier that protects all company assets. To prevent intruders from accessing company grounds without authorization we have many choices in physical controls such as surveillance cable/laptop locks, cameras, security guard, alarm system, access control scanners at entry points, mantraps. As a preventative measure from property break-ins, all lower level (easily accessed from outside) office windows must be protected by installing window bars and/or using fence that secures all company property limits. In addition, a mantrap interlocking door control would greatly increase security.
Application Controls(AC) COBIT assumes the design and implementation of automated application controls to be responsibility of IT, which is covered in the Acquire and Implement domain based on business requirements defined using COBIT’s information criteria. The COBIT IT processes cover general IT controls, but only the development aspects of application controls.
