Network Security Check

Regular Network Security Check for Maximum Protection

Network security check covers actions that are performed towards the computer network and its services. The purpose of network security check is to protect the network as well as its services. It is out of question that as the information technology advances, the risks are also increased significantly. Virus is only one of many kinds of threats that haunt the computer network. Companies are forced to be more and more aware of the possibilities of their assets being attacked by viruses. Some of those viruses can be so severe that important data might be erased permanently. If this happens, it will be a total disaster for a company and therefore network security check becomes very important.

Network Security Check

Protection is best when it is performed regularly. How often a network security check should be conducted may vary from one company to another. The frequency of network security check of a company depends on its characteristics and needs. If a company involves high data traffic using the computer network, then the network security check must be done more often that those companies with minimum use of IT. In general, network security check is performed in quarterly basis, but for companies that are in need for high computer network reliability and security, network security check may take place in monthly basis.

The whole point of conducting network security check is to provide maximum protection to the computer network. Other than viruses, intruders are also the things that are prevented by conducting network security check. Hackers are growing in number from day to day and no company should neglect network security check and put its secret information in jeopardy. Without maximum protection, any hacker could penetrate the network system and view or even steal some confidential information. Network security check that is conducted regularly will make sure that those hackers will not find the door to access the company network that is not intended for public access. If you are serious about protecting your company, contact network security check professionals and have them secure your company computer network regularly. Protection is crucial. Prevent intruders from penetrating your company’s data vault before it is too late.

Why Network Security Audit is Crucial

Network Security Audit

Network security audit is something that is considered very important by people who make use of computer networks in running their business. But why exactly is it so important? In understanding network security audit, we must remember that when it comes to protecting the IT assets of a company, maintenance is the most important things. Maintaining all the assets is crucial since it can guarantee the business to run smoothly. Network security audit is one of the aspects of maintaining the IT elements of a company. Network security audit, just like any other maintenance actions, must be done regularly. It is not something that is taken place once for a lifetime. Normally, network security audit is taken place in quarterly basis. However, network security audit can be performed more frequently depending on the company’s IT characteristics and needs.

In this era of high end technology, companies are more and more aware of pretectic their assets by regularly conducting network security audit. As their needs of reliable IT and secure network increase, network security audit becomes more and more necessary. The fact that the world of IT comes with benefits as well as risk drives companies to take actions in order to protect the companies’ confidential and assets that are sewn together within the network. Threats and perpetrators are haunting and in the time when it is least expected, they attact the very core of the company’s network. This can result in massive destruction as hackers stealing important data may be involved.

Network security audit is intended for protecting the network form intruders. It means that it is a preventive action that might save a company from falling down due to IT intervention from the outside or even from the inside. In order for network security audit to be performed well, it is very important to use the latest and most effective software and techniques. When it comes to performing network security audit, it is best if it is left to the experts. They will conduct network security audit with great attention to details. These experts are easy to find at the local network administrator. Network security audit is crucial for a company’s well being. Therefore, it should never be taken for granted.

SAE J1939 Protocol Stack

SAE J1939 Protocol Stack Overview

SAE J1939 Protocol Stack

SAE J1939 is used to make sure that all components of a commercial vehicle, such as medium and heavy-duty truck, can communicate each other properly and can be diagnosed systematically. This coding standard is outlined by the Society of Automotive Engineers as a high level communication protocol on a Controller Area Network (CAN). This protocol is needed to accommodate various systems of a vehicle, particularly the fleet management system. This system broadcasts many important data of the vehicle including vehicle speed, cruise control, clutch switch, acceleration, VIN, total engine hours, engineer temperature, and other necessary vehicle information that is needed to be observed when the vehicle is operated when it needs to be diagnosed. SAE J1939 protocol is an enhanced replacement of the previously used SAE J1587/J1708 network protocol.

This protocol defines five of seven OSI layers models. The five OSI model layers that are defined by this protocol are the physical layer model with its bits protocol data unit, the data link layer model with its frames protocol data unit, the network layer model with its packets protocol data unit, the transport layer model with its segments protocol data unit and the application layer model. All of those five OSI layer models are handled by a single software library called the SAE J1939 protocol stack.

This protocol stack is used to translate the received CAN inbound data frames so they can be observed and analyzed by the users. It also provides development of J1939 devices in a quick and simple way. When it is applied, it will transmit and receive specific messages, treats J1939 transport protocols, establish communication with numerous nodes simultaneously, support address claiming process, and transmit and receive messages cyclically with timeout monitoring. The application of this protocol stack enables the developer to develop the application with improved concentration.
