Different Tools Used For Network Security Audits
Network security is one of the most important functions that an organization requires.
However, a complete assessment of the network security is not possible without taking into account the importance of the various factors that affect the performance of the system. In order to achieve a full network security audit, it is essential to investigate the system from every angle, from the client to the firewall to the virtual private server to the network backbones.
Apart from the various aspects mentioned above, there are several other things that need to be taken into account. A complete network security audit must also include the system configuration of the servers and their appliances. It must include all the systems, in addition to the equipment and the configurations that they use.
The complete network security audit needs to take note of the software that is used in the server or in the appliances that have been procured. The IT infrastructure of the organization must be thoroughly examined including the software used by the system as well as the hardware. This will allow the investigator to detect any problem that might have been overlooked in the past.
The environment in which the network security system is running must also be scrutinized. Every aspect of the network should be considered, starting from the equipment used by the organization to the Internet connection. The investigator must learn all about the details that he needs to know about the security of the network.
One of the best ways to determine the performance of the network is to track the activity of the users. The logs of the network operations that are opened and the activities performed by the users must be reviewed and studied. If any unauthorized users or commands are detected in the logs, then the complete network security audit needs to be conducted.
There are various tools that can be used for the network security review. Some of them are discussed below. They are:
There are many people who are skeptical about conducting a network security review. This is because of the complexity of the task. However, such reviews have their uses. Such reviews help administrators identify gaps in the network security, which can be rectified easily.
Malware like “RAT” (Remote Access Trojan) is one of the most common problems that administrators encounter in their network security audits. They scan the network to find if the malware has infected the systems and to determine how it operates. It also includes the inspection of the services that the malware provides, such as the emails.
The different levels of network security can be measured with the help of the NetTraffic software. This software provides a real-time view of the traffic that is going in and out of the network. It is able to show the ratio of data to traffic in a comparative manner. However, this is not the only option available for a network audit.
There are other tools that can be used to determine the effectiveness of the firewall, the open ports, the problems that are being experienced by the firewall, the status of the firewalls and the problems that are occurring in the virtual private server. This system runs under the supervision of the administrator. Once the necessary changes have been made, it can start recording the events that are taking place on the network, in addition to the events that are taking place on the appliance, on the storage servers and the routers.
There are many systems that are based on the Microsoft operating system. However, they are also vulnerable to viruses and spyware that come from the Internet. It is important for administrators to know the systems and the services that are running. The easiest way to do this is to use an intrusion detection system, which monitors the network at all times, and will alert the administrator about any problem.
These tools are some of the system security auditing tools that can be used to detect any issues that might occur in the network. Most of these tools are run by the administrator and are very easy to use.
