Itm 431 Module 1 How to Achieve Business Information Security in Cyberspace

Firewall: A firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analysing the data packets and

There are several different types of firewalls a company can purchase to insure their information is kept secure and only accessed by those who the company has given access to. A firewall can be purchased from an application service provider who can maintain the software for the company, this can

Firewall is “a computer security program that blocks incoming network traffic based on certain predetermined criteria”. Firewalls have details logs, that can hold a wealth of information about the network to the forensics investigations. The firewall logs can also have details about the hardware failures. Successful/unsuccessful connection attempts, users added on, and any permissions changed. You can also find evidence on the backdoors.

having a personal firewall to protect an individual users desktop system from public networks by monitoring all the traffic that passes through the computers network interface card will secure a home user from spyware, hackers, and other online threats and risks.

A firewall is a system or group of systems that enforces an access control policy between two or more networks. The means by which this control is accomplished varies widely, but in principle, the firewall is a pair of mechanisms, one that blocks traffic and one that permits traffic. Some firewalls emphasize blocking traffic, while others emphasize permitting traffic. The most important thing to recognize about a firewall is that it implements an access control policy. If you don't know what kind of access you want to permit or deny, or you let someone else or some product configure a firewall based on judgment other than yours, that entity is making policy for your whole organization.

The firewall is an equipment or software which protect the ports of PCs on the LAN. For the reason behind this policy, "Remote Access" might mean access to the Local Area Network from any area outside the firewall by any method, including access through Virtual Private Network (VPN), dial-in modem, Telnet, SSH and some other technique for getting to the LAN from outside the firewall.

The increase in database threats and risks has led to increased need to boost information security especially database security. Some of these security risks and threats include:-

The interdependent network of digital and communication infrastructure is referred to as the cyberspace. It includes telecommunication networks, the internet, and computer systems. Cyberspace underpins every facet of our modern society. It provides support for civil infrastructure, U.S. economy, national security and public safety. The term cyberspace can also be used to mean the interactions of people and the virtual information environment. Cyberspace enables the growth of effective and more efficient business processes.

Firewalls: A firewall is a security network that can be either hardware or software or a combination of both. A firewall protects your personal information and computer by acting as a barrier so that viruses or unauthorized internet users from accessing your information. In relation to the website performance, a firewall is used to protect the website and your computer from users that are not authorised to access it and to stop hacker from manipulating the website's code. It also will prevent your website from being infected with viruses or bugs which will make the website take longer to load.

A firewall is a collection of components, interposed between two networks, that filters traffic between them according to some security policy (Cheswick & Bellovin, 1994). Due to the increase in network attacks and awareness of cyber security firewalls are used not only in companies but also in home networks. Firewalls are the frontline of defence to secure the networks from security risks and attacks from cyber criminals. Firewalls filters network traffic based on filtering rules defined by the firewall administrator or admin. Although firewalls protects from network attacks, virus etc, it depends on the firewall policies defined, if the policies are not defined properly it proposes a security risk and limits the effectiveness of firewall security. . There are mainly three types of firewalling techniques based on the OSI layer in which the firewall is acting on. They are (1) packet filters, which inspect each packet passing through them, (2) application Gateways which act on specific applications such as FTP, Telnet etc and (3) circuit level Gateways, which apply security mechanisms whenever TCP and UDP connections are established. Firewalls have

An antivirus offers great protection and is an effective way to protect against viruses. However, a firewall is a necessary tool to help keep attackers off the network based on rules set implicitly to filter the web traffic and protect files. While antivirus is a great tool to help keep you safe, adding a firewall will give the

Small and medium-sized enterprises account for the majority if the share in the market and most of the employment in certain sectors of the economy. They have unique characteristics that both work to their advantage and prove a burden. Activities involving information technology has drastically increased and many of these businesses bring up questions of how beneficial it can be to the profits and partners made. Professional managerial skills are vital in properly using information technology and several business are investing in the rapidly increasing method of increasing business. Managers have to consider the initial costs, the willingness of the business to change ways, and long term effects of adopting new methods involving

Business is often at the forefront of technology since it helps generate the next great economic idea or surge. Most businesses now use, at the very least, a personal computer, modem or cable connection, the Internet, and printers. They keep customer records electronically, and are better able to find ways to serve the needs of their current and future customers. Companies can outsource customer service, order lines, or even programming and technology, saving between 30-70 percent of in-house costs. E-Mail and the Internet have shrunk the world so that businesses of all sizes can have global customers. In addition, the efficiency of order entry, inventory control, and supply chain integration make it more cost-effective to do business in many areas. We should not forget marketing databases keep track of customer desires, past purchases, and even what customers look at on a web site algorithms can then generate lists of similar or ancillary products and services, creating a more robust experience and relationship with the client (Wilson, 1999).

Every computer on a network has an address commonly referred to as an IP address. A packet filter firewall checks the address of incoming traffic and turns away anything that doesn’t match the list of trusted addresses. The packet filter firewall uses rules to deny access according to information located in each packet such as: the TCP/IP port number, source/destination IP address, or data type. Restrictions can be as tight or as loose as you want. An ordinary router on a network may be able to screen traffic by address, but hackers have a little trick called source IP spoofing that makes data

Firewall is a basic and easily implemented methods of the network security (software based). It will allow authorized access to computer while blocking unauthorized access by configuring access conditions based on user defined rules, IP. VPN will be used to encrypt connection across a network while using the internet as transmission medium. It builds a much secured data connection. VPN connection software encrypts the data being sent between one places to another.
