Computer Security is a branch of technology known as information security as applied to computers. Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. The objective of computer security varies and can include protection of information from theft or corruption, or the preservation of availability, as defined in the security policy.

Technological and managerial procedures applied to computer systems to ensure the availability, integrity and confidentiality of information managed by the computer system

Computer security imposes requirements on computers that are different from most system requirements because they often take the form of constraints on what computers are not supposed to do.

Typical approaches to improving computer security can include the following:

o Physically limit access to computers to only those who will not compromise security.

o Hardware mechanisms that impose rules on computer programs, thus avoiding depending on computer programs for computer security.

o Operating system mechanisms that impose rules on programs to avoid trusting computer programs.

o Programming strategies to make computer programs dependable and resist subversion.

Computer Security has three Layers:

o Hacking

o Cracking

o Phreaking

Hacking:

One of the biggest concerns in internet security is hacking. Hacking could be of different levels of seriousness. Hacking could be just plain annoying and disturbing but it may be very severe to the extent that your finances, security, and even national security are put to risk. Critical as it is, we should make sure that we are doing ways in order to, if not eliminate, minimize the possibility of us being hacked.

A way to minimize attack is by being doubtful of what we see on the internet. Sites and advertisements that have offers that are just too good to be true usually contain viruses, spyware and other malicious software programs that enter your system and make it susceptible to hacking attacks. Hackers would entice us to click on the incredible offers on sites and advertisements so that they could trap us. We should be cautious whenever opening these types of offers on the internet.

Spam is annoying since you have no business with the sender. They can also be highly dangerous for your computer if you are careful. Emails must therefore be carefully checked before been opened so that you don’t get affected.

It is dangerous when there are links and other files attached to the email. You must absolutely know and trust the sender before clicking on these links or downloading the attached files as they can be malicious programs that will disrupt your machine.

Email protection software is developed by companies who try to aid the ill effects of spam. There are a couple of some free software around which still protects your computer.

These programs normally have a host of options that you can choose from in protecting your machine. However don’t go for any software as there are things that you must look for.

Checking reviews about the software is a great way to start. You can check comments left by previous users and see if it will meet your needs. Also make sure it will not conflict with your emails and that it will work smoothly with all your email clients.

Often, the computer that runs in a corporate setting or university will have limited access to the Internet, thanks to the blocking software installed. However, with a proxy server, you can navigate around this difficulty.

Quite often, the blocking or filtering software that will be used by the company will be the firewall. This usually consists of software (and sometimes hardware too), whose purpose is to detect the sites that the computer accesses on the Net. This is done through tracing of the IP address of the user’s PC. Aside from tracking though, others will have blocking capabilities built in.

This can make it very, very difficult if not impossible to go to these banned sites without getting caught or causing the system to crash altogether. A proxy server, however, can go around this easily.

There are a lot of these available on the Internet, but the real key to using them is an understanding of just what is going on. In simple terms, the server will cloak the user’s computer so that every time a blocked or banned site is accessed, the IP address, which is always requested by the host site and is detected by the firewall, is not shown and instead, the IP address of the server is used.

There are so many ways to access the web, and all the of smart devices account for even more traffic on the World Wide Web. This overflow of users calls for increased website security that will offer a noticeable extension of online protection.

One of the best solutions is a malware scanner. The software applications that are written to attack websites, computers and email accounts have become even more dangerous than they were in the early stages of computing. Anyone that accesses the web knows about all of the dangers that various sites can cause. Unfortunately, the majority of the users that are exposed to viruses fail to take the needed precautions to prevent these attacks.

Malware takes all shapes and forms. It can come in the form of a virus, worm, spyware and any other software that was created with a malicious intent. These attacks are sometimes triggered simply from visiting a particular webpage. There are other times when the application is unleashed through the download of a file.
