Update business security technolgy
All computers used in your business should have anti-virus software installed, and the virus definitions must be updated at least once a week (many providers have a one-click update). All incoming and outgoing traffic should be scanned for viruses, as should any disk or CD that is used, even if it is from a ‘trus ted’ source. At least once a month, computers should be scanned for viruses. If your computers are connected to the Internet, and especially if you use a broadband connection, you must deploy a software firewall. This will help to prevent malicious code from entering your computer and potentially compromising the confidentiality, integrity and availability of your network. It will also help to stop your system being used to attack other systems without your knowledge. Software firewalls for use by nonprofessionals are readily available at a reasonable cost. Your operating system, virus control software or ISP may also offer a firewall. Consumer and popular trade magazines compare firewall functions and features of well known products, and so are a good source of information. Free shareware firewalls are available, but these usually require expert knowledge for correct use. o If your business has a small network that is connected to the Internet, you should consider deploying an ‘all- in-one’ hardware box that contains a firewall, anti- virus program and an intrusion detection system. This will greatly simplify your use and maintenance of essential Internet security technology.
