In general terms, "security software" refers to a range of computer applications designed to protect the integrity of your data, your computer and your network. It covers everything from firewall and password protections to data encryptions and Internet filters designed to ensure children don't view material intended only for adults.
Features and Advantages of Security Software
Software manufacturers offer numerous computer security software products, each of which is typically designed to perform a single specific function. Some of the most common applications you'll encounter include desktop security software, network security software, antivirus software, encryption software and Internet filter software.
Desktop security software is primarily used in places of business to prevent users from accessing or deleting important files or critical applications. The ability of a given user to make changes to data or documents may be limited, and users will face restrictions on the use of removable storage devices.
Network security software provides your network's administrator with the ability to detect, analyze and act against possible threats to network security. This type of Internet security software also provides tools for requiring users to supply credentials to gain network access, and maintains a database of authorized individuals to ensure nobody who's not supposed to be able to use your network is able to get on it.
Antivirus software periodically scans your computer to detect potential threats, such as viruses and spyware, and notifies you if you encounter a suspicious file or website. Encryption software protects your data by making it readable only to users with the authorized cipher key, and Internet filter software can be used in both homes and businesses to prevent computer users from gaining access to specified sites or types of Internet content.
Security breaches cost businesses hundreds of millions of dollars each year. If you have sensitive data to protect, security software makes an excellent investment. Parental controls also provide peace of mind to parents who want to ensure their children surf safely through the potentially dangerous world of cyberspace.
Popular Security Software Products
While free security software, particularly antivirus applications, is widely available, they are usually only offered for trial periods and with limited features that provide less than total protection. Therefore, it is best to invest in a licensed product.
The list of quality products goes on and on. McAfee, Avast!, AVG and many others produce effective antivirus software. SecretAgent, Alligator Data Guard and Invisible Secrets are popular choices of encryption software, and Intel, Microsoft and other computing giants produce their own network software support applications.
