Wireless Security

The only problem with wireless networks is network vulnerability. A wired network due to limited access to the physical security of the actual network, and a port to the Internet (gateway) provides a firewall or two there (or had better). This can block unauthorized access to your network more. The difficulty in implementing cable networks has discouraged many people from installing networks in the first place.
Then came a long wireless, which, as I mentioned earlier in the article, the game network home more attractive and less intimidating. With a wireless network means. Physical security, which is inevitable in a wired network, not only because everyone within range of your Wi-Fi network to see your network, and can, if not properly secured access. If your wireless access point is not the router on your network can slip behind your firewall from the outside. What happened in my college, it was an apartment complex behind a part of the school, and other technicians that someone grafted to the network. It has a wireless network is not secure, nobody did anything bad to him, she did used to access the Internet, but he never knew.
There are some practices to make sure that nobody should try with your connection or your network. First and foremost, you need to WEP (Wired Equivalent Privacy) to implement, which is an encryption function that prevents unauthorized users from accessing your network. There are at least two types of encryption in 802.11b (128 and 64-bit) and have probably changed every two weeks or more. WEP encryption is used to well-being the responsibility of the user, but now I see the material of the box configured with at least one key, forcing the user to configure their PC to connect.
Is important with WEP wireless security, but not rely on them alone, there are other security measures that you can implement as well. Some wireless devices, you can set a MAC address filtering, witch can really spice up your security. A MAC address is an identification number that manufacturers stamp on a network device, and is (or should be) quite unique. If the security is in place, so if anyone knows the WEP key, they still can not enter the network, denied access because your wireless device.
There are two other things you want to do to simplify your network could be: The first thing you need to do is go through and change all default security settings and passwords. The reason I say this is the most routers and access points are usually filled with a lot of these configuration fields (eg username and password or SSID) with values generic for easy installation. The worst thing is that people can use these parameters for you to give access to your network. On the other hand, it is a set of routers your default SSID broadcast on, it means it sends the name of your physical length of your network. Not good, even if your neighbors can not access the security of your network, they will constantly whenever they start one of their wireless computers.

the difference between a Virus, Trojan, and Worm

Virus - Technically, a virus infects other files (attached or inserted into it). In general, they infect program files or MS Office documents. From there, you can play, damage, etc. Unlike a worm, do not work as one (except perhaps

infect a particular file).

Worm - This is almost identical to a "real virus", but lives in itself and usually do not infect other files (although it can be replaced). Usually copied using email, networks, disks, etc. Again, these are very similar to a real virus, and can do the same kind of damage.

Trojan Horse - This type of program does not copy, but do harm to your computer. These types of programs are based on people to move and run. They do it by e-mail. The idea is to make the program think it is something benign such as a screen saver or a joke, was sent to.

How Firewalls Work

This means that there are people who want very badly to get into your system or network. Maybe they want to steal information, cause just as much destruction as possible to use, or system for their own purposes. If you are online a lot or a broadband connection, attempts to enter the system to be relentless.
I think there are three main areas of defense against these threats. Anti-Virus (of course), firewall and spyware removal Some programs are more important than others, but none is without meaning. What I want is to give all our readers at least a good idea of ​​what to do these firewalls and anti-virus to protect your system. I will try to highlight the features of these utilities, and even some best practices that you can implement.
This week, I will discuss the first line of defense between you and the Internet firewall. A firewall is not that you still have a large number of viruses to stop, unless it is the type of virus scanning, open ports that proactively 32.Sasser which recently held on the stage of the virus. When firewalls are really in the game is in the area of ​​access to the Internet or a network.
There are two types of firewalls: hardware and software.
A hardware firewall is a common router. In a small network is in between your PC and the modem. These firewalls offer the ability to hide your PC against others on the Internet. You private IP addresses through a process called NAT (Network Address Translation) or DHCP (Dynamic Host Configuration Protocol)
I may be a few people who are not familiar with IP addressing lost. This can quickly become confusing. To put it simply, a router to use the internet address that your ISP has inflicted on you and give you the PC connected to the router a private IP address generic (not valid for the Internet). The other main task is to port (these are numbers that are associated with certain professions, for example, most email clients and servers use SMTP port 25 and POP3 port No. 110 use) ports can be a security problem as seen in the past and may close a hacker easily. open ports on your PC with the world When hackers try to scan your network for vulnerable ports, the firewall simply drop the packets because they contain data that are not required a PC on the network.
Software firewalls are a little different and they have good and bad points. First let me start by saying that it is always better not to have a firewall at the time. The main difference between the two types of firewall is that you can. An external device, which runs on its own hardware Firewall is a software application that runs on your PC. This is a drawback, I think, because there is another application that runs on your PC, try as you surf on the Internet and cause overloading of resources and slow things. In the old PC In theory, firewalls are really the same, except that one of the main differences is a software firewall has no address translation services (eg DHCP or NAT).
Software firewalls have characteristics very well, however. For example, a software firewall is ideal for someone new to learn in this area of ​​PC and want more. I say this because most of these firewalls is quite different from a simple interface to use more "techie" understand the router interfaces research.
Software firewalls also function for Internet access which I find very informative, as in most software firewalls I have when a program attempts to access the Internet, the firewall s' appears asking if this action should be to try to come whenever called each time, or deny Internet access to the program. Notify Most software firewall, even if someone from outside your firewall and take a lot of time, obtain the IP address of the party at the other end of the action. Both functions can be used to better protect your PC, in some cases, you may even be able to catch a hacker attempts on your PC ISP giving its IP address, and then ask what is the IP address while sending request ping obtain your IP address.
In fact, I helped a client do this, they called me and said that there firewall kept repeating noise and popping with windows there are some activities here firewall. You said it's for a few days. Well, we opened the port and I saw in the newspaper describing what was the activity which they are. There were a number of pings to fight fire, but the software we have the IP address, and then we opened a command line and return ping the IP address, and it came with their ISP domain name. She called the ISP and spoke with them about it and address it happened. I would not be surprised if he got fired from his Internet service.

What Is Spyware?

Spyware is a type of malware, or malicious software designed to infiltrate a computer system without the owner’s consent. Once installed, the spyware starts working and performs tasks that it was designed to do such as collecting little bits of information at a time about users without their knowledge.

Again, malware is an expression, or a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code. The term “computer virus” is sometimes used as a catch-all phrase to include all types of malware, including true viruses.

Spyware can interfere with user control of the computer in other ways, such as installing additional software and redirecting Web browser activity. Spyware is also known to change computer settings, resulting in slow connection speeds, different home pages, and/or loss of Internet or functionality of other programs.

The presence of spyware is typically hidden from the user, and can be difficult to detect. Typically, spyware is secretly installed on the user’s personal computer. Sometimes, however, spywares such as keyloggers are installed by the owner of a shared, corporate, or public computer on purpose in order to secretly monitor other users.

USB Security Software Helps to Keep Your Computer Safe

USB security software is an essential solution to have in many scenarios, especially in larger commercial networks where information leak is something that needs to be prevented as much as possible. Also, for businesses which regularly rely on their computers for their day-to-day functioning, it is of utmost importance that computers do not end up getting bogged down by malware or other technical problems. In commercial or public networks especially, unrestricted usage of USB devices is something that should be avoided, since USB drives can contain malware or be used for leaking important, confidential information. USB security software provides users with an important additional safeguard that will give network administrators and the owners of home computers alike a higher degree of power over how other people use their systems. One such solution which provides everything you need for USB security is Everstrike's USB Security software. Using this solution, you can help protect your computers from the connection of any unauthorized USB devices, though it will not simply block off the ports entirely. What it does allow you to set restrictions on is hardware such as USB memory card readers, flash disks and other removable USB storage. The program will not cause any problems for other types of USB device such as USB printers, keyboards and other input devices. These can continue to be used as normal. USB Security will allow you to secure individual computers such as in the case of home use or entire networks. This makes the software extremely versatile, making it highly useful in all sorts of different scenarios ranging from small, single computer home installations or entire networks over extensive commercial installations. When used on a network-wide basis, USB Security can also be centrally deployed and managed, allowing network administrators to easily enforce their security policies from one, central location. Helping to control file transfers, guard against potential information leak and prevent infections from malware, this simple, yet powerful utility provides a solution that in many cases should be considered essential. Using the program's settings, administrators can easily set a white-list of USB devices deemed as safe. These can include devices such as printers, scanners, or anything else in addition to USB storage devices which are explicitly allowed by the administrator. It is perfectly possible, an easy, to allow access to specific USB storage devices which, using the software, you can assign passwords to for added security. This means, that when such a device is connected to a computer running USB security, it will prompt the user for a password before they can continue. USB Security is also completely unobtrusive. It runs invisibly in the background and is completely undetectable to PC users. It will not bombard the user with any warning messages or pop-up windows unless explicitly configured by the system administrator to do so. Another thing that administrators will certainly appreciate is the fact that the software can be installed and managed from the central server computer. Settings can be applied this way for all of the computers across the network.
