The main technique of fixing software security vulnerabilities is the use of security patches. At present Microsoft gives out security patches on a monthly basis, and other software and operating systems have special security teams for presenting software patches every time a vulnerability announcement is made.

Virus Protection

A virus that you find on your computer is a minute executable program or a section of code that can cause malfunction or even a crash on the system. Preventing such attacks using a good antivirus program is an advisable thing to do – this is a lot better than having to deal with a virus-ridden computer later on. You should compulsorily use an updated anti spyware tool to keep your computer off inside and outside threats apart from such viruses. You need to lift the level of security of all the web browsers in your system. Make your security settings very firm by making use of a hardware or software firewall. See that you make it a habit to backup all the critical data on your system. Avoid installing on your system any unused programs. Make sure you double check before downloading any files from the web. Avoid using floppy disk for data transfer purposes on your system. Keep your gateway computer and all client systems in the network updated with strong anti-spyware, antivirus and firewall.

Hardware/Software Firewalls

A firewall is a fortification that you set up basically between your own network of computers and the web. You can buy hardware firewalls as a separate item; however, nowadays the hardware firewalls are normally there in broadband routers. Hardware firewalls make use of packet filtering for checking a packet’s header to find out its destination and source. The resulting info is evaluated against a predefined set of rules that decide on whether to drop or forward the packet. Software firewalls, on the other hand, are setup on the computer itself and the user has options to make customizations on it. Such a software firewall helps in guarding the computer from external hack attempts and also against common email worms or Trojan programs.

Backing up Data

Backing up is all about creating data copies which may be useful later on in the case of a possible loss of data. The main idea is to recover your data even after it gets lost, whether by data corruption or removal. The other function of backups is of course to pick up data from a preceding time. Contrary to usual belief, DVDs are not the sole option for doing data back-ups. There are other more convenient options; you just have to pick the right one for your needs. You will also require a backup for the backup itself. You can maintain a copy of the data offsite apart from one at your actual physical location. This will help just in case there is any untoward incident like flood, theft, or fire. If at all possible, both your backups should be something that is done automatically and regularly. Apart from various online backup services, the use of flash drives, hard drives, optical drives are the most popularly employed methods.
