    A firewall is a combination of hardware and software that controls the flow of incoming and outgoing network traffic. Firewalls prevent unauthorized users from accessing internal networks. They protect internal systems by monitoring packets for the wrong source or destination, or by offering a proxy server with no access to the internal documents and systems, or by restricting the types of messages that get through, for example, e-mail. Intrusion detection systems monitor the most vulnerable points or “hot spots” in a network to detect and deter unauthorized intruders. These systems often also monitor events as they happen to look for security attacks in progress. Sometimes they can be programmed to shut down a particularly sensitive part of a network if it receives unauthorized traffic.…

    A virus is a self-replicating program that copies itself from machine to machine, usually over a network. Viruses spread by attaching themselves to other programs. They have various effects, from displaying harmless messages to erasing hard disks. Unlike worms, viruses focus on damaging local data (Oz, 19). A virus can be embedded in a Trojan horse. A Trojan horse is a useful program, like a game, that has malicious software deliberately embedded within it. There are other poorly written software which are vulnerable to an SQL injection attack.…

    An antivirus program protects a computer against viruses by identifying and removing any computer virus found in memory, on storage media, or on incoming files. When you purchase a new computer, it often includes antivirus software. Antivirus programs work by scanning for programs that attempt to modify the boot program, the operating system, and other programs that normally are read from but not modified. In addition, many antivirus programs automatically scan files downloaded from the Web, e-mail attachments, opened files, and all types of removable media inserted in the computer (Karanos 201-205).…

    As companies increasingly rely on the data contained on their computer systems, threats to the data are also growing. Threats to data, or to information, can come in the form of a breach of confidentiality, a violation of integrity, or a denial of availability. These threats can come from various sources including computer hackers with malicious intent, natural or unnatural disasters, the lack of security policies, the failure to enforce security policies and computer viruses. Computer viruses pose as serious a threat to data as can a malicious hacker. In order to thoroughly protect a company’s information, one must focus on protecting against all possible threats, including computer viruses. Although infection of computer systems by a virus is generally unintentional, the possibility of infection is real and without the proper protection, imminent. Computer viruses are designed to spread from one file to another, from one program to another, from one machine to another, and even from one network to another. Viruses threaten the integrity and availability of data. Data have become the backbone of most companies today, and therefore any threat to a company’s data cannot be tolerated. Time, resources and money must be invested to protect a company against the harmful and destructive intrusion of computer viruses. At first glance it would appear that protecting computers from viruses is a relatively simple task. On the surface this task involves selecting an anti-virus software package, installing it, and running the virus scan, rendering the computer virus-free. Unfortunately the process can be quite intricate, and require as much time and effort spent planning as on implementation. An enterprise wide anti-virus initiative involves numerous tasks, which at a high level can be broken into the following phases: planning, implementation and maintenance. Other phases may be identified for any given project and should be included as…
