Emery makes a series of recommendations for small businesses that conduct business over the Internet. First, he stresses that all Internet software should be kept as far as possible from regular system software. For example, a small business might use a standalone computer to run its Web server or place a firewall between the Web server and the rest of the computer network. Emery also emphasises that small businesses should never store customer information—especially credit card numbers—on their Web server or any other computer connected to the Internet.
It is also a good idea to avoid putting any sensitive or proprietary company information on these machines. For small businesses, which may not employ computer experts who are qualified to establish and monitor Internet security systems, Emery recommends leaving e-commerce security to an Internet Service Provider ISP.
In any case, small business owners should weigh the costs of implementing a secure Web server—and hiring the staff to monitor and maintain it continually—against the potential profits they may receive from online sales. Searching for the best CCTV security systems? Give Security Systems a call. For hardware and software security measures to be effective, small businesses must incorporate computer security into their basic operations. These policies should encompass computer activity at both the user level and the system administrator level.
At the user level, one of the first tasks is to educate users about the importance of computer security. Passwords should be at least eight characters long and include letters, numbers, and symbols. Employees should be advised to avoid obvious choices like names or birth dates. In addition, employees should be instructed never to store their password in a drawer or on a bulletin board, never to let anyone else log into the system using their name and password, and never to leave their computer on and unattended.

Computer system administrators should be involved in developing and implementing security policies and procedures. First, they recommend keeping servers in a locked room with limited access. Second, they suggest separating system files from data files on the computer network.
Third, they advise administrators to install virus scanning software on all company computers and prohibit employees from copying outside programs or files onto the web. For example, it would probably not be necessary for a person in accounting to have access to personnel records. The administrator should define user and group-access rights to allow employees to do their jobs without making the system unnecessarily vulnerable to attacks from disgruntled workers.
Another sound policy is to require employees to change passwords frequently and to immediately disable passwords when employees leave the company or are terminated. Administrators should also grant Internet access only to those employees who need it for business purposes. To prevent unauthorised external access to the computer system, administrators should define access rights granted to suppliers and customers.
They should also ensure Internet ports are secure and possibly implement a firewall to protect the internal network from outside access. Another important policy is never to store employee passwords on any computer that is connected to the Internet. For example, network auditing software tracks users who are accessing the system and what files are being changed.
It also alerts the administrator to excessive failed log-in attempts. The best auditing packages generate network usage reports on demand, which allows the administrator to reconstruct events in case of a security breach. As Emery noted, it may be helpful to prepare a printed emergency response guide for both employees and system administrators. In a worst-case scenario, any guidelines stored on the computer system would be useless.
Emery also outlines the basic steps companies should follow in case of severe system problems. First, employees who suspect a concern should contact the network administrator. The administrator should then get in touch with technical support at the ISP to determine the extent of the problem. At this point, the administrator may wish to contact the small business owner or appropriate non-technical managers to inform them of the problems.
Management can then decide whether to contact local law enforcement and what to tell employees. Information security analysts are in high demand. According to the Bureau of Labor Statistics, employment opportunities for information security analysts are projected to grow 18 per cent between and , much faster than the average for all occupations.

Internet frauds come from all backgrounds and all age groups and for some reason they feel the need to post malicious software on the internet to cause serious damage. This results in the entire computer being formatted clean and reinstalled an inconvenience that no one wants to bear. Read more ideas to protect yourself here:. The Case for Strong Passwords.

Sharing a password with a friend, not logging out of your internet banking and opening up a spam email and clicking on the link can all result in devastating consequences. People are becoming more aware of the dangers of the internet and using Wi-Fi connections available throughout the country they are opening themselves up to these unwelcome guests, this is why they are taking their security seriously.

Firewalls explained and why you need one. June 17, Firewall defined A firewall is a security device — computer hardware or software — that can help protect your network by filtering traffic and blocking outsiders from gaining unauthorized access to the private data on your computer.
What does a firewall do? How does a firewall work? Types of firewalls There are software and hardware firewalls. Packet-filtering firewalls A packet-filtering firewall is a management program that can block network traffic IP protocol, an IP address, and a port number.
Proxy service firewalls The proxy service firewall is a system that can help protect your network security by filtering messages at the application layer. Stateful multi-layer inspection SMLI firewalls The stateful multi-layer inspection firewall has standard firewall capabilities and keeps track of established connections. Unified threat management UTM firewalls A unified threat management firewall is a program that combines the functions of the SMLI firewall with intrusion prevention and antivirus.
Next-generation firewalls NGFW Next-generation firewalls are more sophisticated than packet-filtering and stateful inspection firewalls. Virtual firewalls A virtual firewall is an appliance used in a cloud-based system, both private and public. Host-based firewalls versus network-based firewalls There are differences between host-based and network-based firewalls, along with benefits of having both in place. Firewall history Firewalls have certainly evolved over the years and become more advanced since the technology first entered the scene.
In late , first generation firewalls developed as attacks on personal computers drove anti-virus products. In mid, internet attacks on networks led to the advent of the second generation firewall; the first stateful inspection firewall was introduced in In early , third generation firewalls addressed vulnerability exploits at the application layer, leading to Intrusion Prevention Systems Products IPS. In , increases in targeted attacks instigated anti-bot and sandboxing products.
In , larger scale attacks drove even more advanced protection. Do you need a firewall at home? Why do we need firewalls? You only log on to trustworthy, known websites. You never give out any personal information unless it is absolutely necessary. You have strong, unique, complex passwords for each online account that you update often. Lost or compromised data Not having a firewall could leave your devices exposed, which could allow someone to gain control over your computer or network.
Network crashes Without a firewall, attackers could shut down your network. How do firewalls work? What does a firewall protect against? What are the types of firewalls? Do you need a firewall? Can a firewall be hacked? Do firewalls prevent viruses?
