Significance of Windows Security and other controls in system performance

An enigmatic word in the computer world is all about windows security. So, what does this windows control and security all about?? At the first look, you cannot make out the appearance of virus in the system because it just appears the legitimate. Also, it is not that difficult to identify these malicious and vulnerable applications that are malware and spywares. Viruses affect the computers in this way; they get attached and give an unauthorized entry into the system through actual applications and software. It may be via email attachment which would have got attached falsely or even from unknown download or the false pop ups of unknown websites on windows.

 

Windows security and the controls have the capability to hack the personal details concerning to confidential information entered in the system. Many essential programs like the task manager can be disabled because of severe exploits that can impede the computer performance. Such infested systems can even run the fraudulent virus detecting software in the system resulting in obvious false results as well. There are many instances when there is an alert popping up on the window showing the flooded virus details and forcing for the ultimate solution to purchase the antivirus upgrade. However, once you get to know that this is a scam and are trying to snatch your hard earned money you should realize that the ultimate solution is not to buy the software upgrade. Instead, you should completely remove and re-configure the system, if not there is no doubt in getting our system to hackers hand.

So, our next question is that how do we remove these from our system and have good windows security?

Here you will find the two common and very popular methods to neutralize the viruses. The first method is by removing them by manual method, but this is quite time consuming and more over it is taxing as well. So, before starting with this method, as a first step, stop the virus windows security which would run across putting efforts to prevent it from removal. However, this initial task requires your personal computer skills because it would have managed to disable the task manager program from your computer. Hence, it would some time and cannot be done swiftly. Hence, start your system in safe mode and disable the virus, after which you can manually remove them from the system.

Make sure you remove all the fraudulent programs, fake files found in .DLL format, unwanted settings on the system and all that you feel is improper in back up software. This task can be easily performed by antivirus software or any reliable anti malware application. These programs are deliberately designed to scan and look for all the malware infected files and then neutralize them. There are several trusted and reliable antivirus programs available in the market and you can try few of them for free under limited validity as well. This will help you to overcome several rootkits and other vulnerabilities on the system application.

What are Web attacks and how do we defend it?

What are Web attacks

It is a common understanding among all the computer users that web applications play an important role in network connected systems and these are the application software which is mainly targeted by the hackers. Here we can fine some good and useful information what are web attacks and how do we prevent these web application being hacked by hackers. Also we will know the risk factors because of these attacks and the counter measures that need to be taken. Hackers perform the web attacks like SQL injection; enumerate the user names, executing the remote codes, format string vulnerabilities to name a few.

When it comes to a web attack called execution of remote code, it is again a vulnerability which allows the hackers easily to access the computer level code by running arbitrary on the server of web applications. These hackers easily retrieve any information from the server as well. The main reason for this vulnerability is improper coding and it is not that easy to troubleshoot this while we test the web application through penetration. However, this is possible to find out while we review the source code. While we test these web applications, you should be aware of this vulnerability exploitation will lead to total damage of system admin rights that is same as the server running along.? Hacking system with SQL injection could be an old method used by the hackers but still this approach is popular. This type of attack will help the hackers to access information from the web server database. Based on the security level of attack, they can access the basic information access to executing the remote and also could lead to complete system compromise.

Vulnerabilities of format string web attack is the result of improper filter on user input sent to the functions like Perl and C. Hacker can make use of %x token to retrieve the data from stack or any other memory device located. You could also create arbitrary data in arbitrary locations using this token. These attacks can create problems in reading, denying service and also writing. Scripting on cross sites will tremendously help the hackers on the web attacks by using malicious URL.?? However, this will work well, if the malicious URL is scripted in such a way that it appears to be the legitimate at the first sight itself. By accessing these kind of crafted URL, hackers can easily execute their malicious activities through your browser, like in Java scripting which will contain the bugs if XXS.

Hackers performing activities by enumerating the user name will help them to keep them notified on the entered user name and analyze them if they are right or wrong. Such vulnerability exploits by the hackers will provide them a platform to make a trial and error with different user names and come up with the required right ones based on the error message displayed on the window. Though the error message avoids displaying the correct user name, you should make sure if your multiple accounts created for testing purpose do not have the same password even, and delete the accounts after testing.
