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.
