Common Network Threats

Common Network Threats:

Internal
• Insider users already have knowledge of the network and its available resources.
• Inside users typically have some level of access granted to them due to the nature of their job.
• Traditional network security mechanisms such as Intrusion Prevention Systems (IPS) and firewalls are ineffective against much of the network misuse originating internally.

 

External Threats
• It is most likely that external attackers do not have an intimate knowledge of a network, and because they do not already possess access credentials, their attacks tend to be more technical in nature.
• Before 2007, viruses were the leading contributor to financial losses for seven years in a row.

Network attacks are evolving in their sophistication and in their ability to evade detection.  Also, attacks are becoming more targeted and have greater financial consequences for their victims.

What is Spyware

What is Spyware?

Spyware is considered a malicious program and is very similar to a Trojan Horse in that you install the product when you install something else. A common way to become a victim of spyware is to download certain peer-to-peer file-swapping products as well as some freeware like games, music or applications. There are even malicious people who actually hide spyware in “anti-spyware” programs. This way people install the program, thinking it will remove existing spyware from their computer but, in fact, you actually install spyware.

In addition to privacy issues (some spyware can transmit every bit of information you enter on the Web back to a third party) . It could also monitor your surfing habits, install unwanted toolbars and change your browser settings and homepage. Some spyware can flood your system with so many pop-ups that it uses large portions of hard drive space and system resources to the point of notably slowing it down, or worse, making your system unstable and unusable.

How to Remove a Facebook Virus?

Have you become the latest victim of the Facebook virus?

Don’t worry you are not alone. This is one of the fastest growing viruses in the world. If infected you need to conduct a Facebook virus removal as soon as possible.

With the growing popularity of social networks it should come as no surprise that virus creators are now targeting them to spread infections. There are a few different ways you can become infected.

1. Getting infected through a friend whose account has been infected as well. Sometimes they will post a link on your page that contains a malicious code within it. Your friend won’t even know their account has been hacked until it’s too late.

2. Downloading a malicious Facebook application. With so many applications out there now, make sure you pay extra attention to what applications you are permitting access to.

3. Receiving a dangerous link from someone that you don’t know. You should only add friends who you really know and don’t add random people. I say this especially for the guys who get friend requests from beautiful women. Often times it’s a hacker with malicious intent.

Once you’ve noticed these changes you must do two things. First you need to change your password as it most likely has been phished out. The virus will use your profile to message your own friends and continue spreading itself.

Second you are in need of a Facebook virus fix. Once the virus gets onto your computer it will attempt to ruin the hard drive and steal private information. So how do you remove the infection before it gets worse?

How to Fix The Blue Screen Of Death

Blue Screen Of Death

A Blue Screen of Death (also known as a stop error, BSOD or bluescreen) is an error screen displayed by certain operating systems, most notably Microsoft Windows, after encountering a critical system error.

There are a lot of possible causes for blue screen errors, but most of them relate to the computer hardware. The cause of a blue screen error can be a temperature problem, a timing error, a resource conflict, hardware failure, a corrupt registry, a virus or simply a device incompatibility or driver error.

How to analyze blue screen errors

The first thing to do to analyze a blue screen error is to check the meaning of the STOP error code. You need to stop Windows from rebooting when a STOP error is encountered. Once the blue screen of death is shown, you can check the meaning of the STOP error code. Together with the filename of the driver or module, this will give an indication of the error cause.

The most common cause of blue screen errors is a device driver problem. Outdated, incorrect or corrupt drivers can cause the system to encounter a STOP error, resulting in the blue screen. The easiest way to fix this problem is just removing the driver from system using windows safe mode or just restore the windows to an earlier time.

Other causes of BSOD :

  • Hard Drive Failure – A hard disk contains subdivisions of tracks, called sectors. Each sector holds a fixed amount of data. On occasion these sectors can go bad and may cause the Blue Screen Of Death.
    Memory faults can easily cause blue screen errors. Vista and Windows have a built-in option to test the memory, for XP you can use a program called memtest86.
  • Virus Infection – Sometimes the virus infection can turn your screen in a fake “blue screen of death”. Check your system – run a virus scan and spyware scan after updating your definition files.

Laptop Screen Replacement

Laptop Screen Replacement

For those that own a laptop, one of the most common problems users experience hardware-wise is a broken or malfunctioning laptop screen. Laptop screens are essential to anyone using their laptop computer.

Troubleshoot Your Laptop Screen Problem

Before you decide to go ahead and  replace your laptop screen, it is wise to troubleshoot the problem. While obvious damage to a screen will usually require full replacement, other types of damage that are visible on the laptop screen may not be due to the screen itself. This is why before you replace the screen, definitely troubleshoot the problem.

If you’ve dropped your laptop or dropped something on it, and the screen has fractured, the diagnosis is easy. Connect an external monitor to your notebook via its VGA-out port to verify that the notebook’s other components still work. If the laptop functions properly in all other respects, it’s time to start hunting for the parts to fix the screen.

If your display problems aren’t the result of visible physical damage, however, the problem may not be the LCD. If your screen’s backlight flickers, shuts down after a few minutes of usage, or doesn’t come on at all, but you can still see a faint screen image, your problem may be the inverter, a small board that supplies power to the backlight. The good news is that these invertors are available for  under $100.  If replacing the inverter doesn’t solve the problem, the backlight itself may be faulty. If that’s the case, replacing the LCD should fix your problem.

If you see gibberish, lines, or a solid color on the screen, connect an external monitor and switch to that display (if you can). If the problem is evident on the external monitor, the issue is likely with your laptop’s motherboard or video circuitry, not the display. If the external display works properly, the LCD or the cables leading to it are the likely problem.
