Network Security Audit
What is a Network Security Audit?
A network security audit is a process of creating a checklist for detecting weaknesses in a system that is being protected. While every company may have different needs, there are some common things about the basic setup of a network that can make a system vulnerable to threats, by having simple things done incorrectly.
Depending on the type of business you have, there may be procedures that will prevent a network from ever becoming vulnerable to attack, or there may be an easier and more automated way of having your own security system in place. The difference can be made in what methods are involved in the system, and the way the attacks are performed.
Once a network security analysis has been conducted, the results will be detailed reports detailing how the system is protecting itself. By analyzing the data collected from the scanning, it can provide the business owner with a much better understanding of what the risks are, and what measures are being taken to protect the network from threats. Once a full and complete report has been gathered, then the business can decide on which steps need to be taken to remedy the situation.
There are four basic network setup that make up the most common cases that require network security audit. This includes protecting the Internet, telephone lines, computer networks, and filing cabinets.
The Internet is the most commonly used site on the web. Although most people use the Internet to go about their daily activities, they have no clue that their actions can be monitored by others online. Companies and government agencies have access to the information the Internet leaves behind on a regular basis. If the network is being monitored, then there could be information that can be used by the users to invade their privacy.
Telephone lines can also be monitored, but if someone is listening to the phone call, then the person is still on the line that they were on at the time. The only thing different is that the person that is being listened to does not know that they are being watched. Computer networks are normally protected by firewalls and other measures.
File cabinets are also vulnerable, and although they may not appear that way, when a threat is made against a file cabinet, then the file cabinet will be touched in a way that causes physical damage to the object. This will then let anyone who knew the physical location of the file cabinet to steal the files contained within.
These types of incidents are the most common instances of potential network threats and can be handled in different ways depending on the type of network setup that the business uses. Different aspects of the system should be addressed in order to ensure the security of the network, such as guarding physical assets, blocking traffic from unauthorized parties, and maintaining internal and external communication.
It is important to remember that the same basic network security will work for any company, though the options will vary. Most companies will have some sort of telephone lines and Internet access, while some companies may also use file cabinets. This means that there is no need to worry about the setup of the network being too complex.
If the systems are simple, then the business can take a look at how they are being managed to see if there are any easy ways to improve the security of the network. For example, getting rid of obsolete software may be able to protect the company from attacks. Another option would be to get a firewall installed, or to install a reliable monitoring software program.
Evaluating Your Business
Businesses should also evaluate the number of employees that use the network. Those that are very large may require additional security measures, or it may be necessary to hire a private security firm to monitor the network.
- This will allow the company to monitor the network and gather information that can be used to protect the network.
- A network security audit can help businesses identify the strengths and weaknesses of the security setup and help them make improvements where needed.
- By implementing measures that were already identified as a weakness, a company can ensure the best protection of its systems.
