Network security is a complex topic. What is the Network Security Mismatch several layers of security that organizations must implement to protect their data?
Network Security Mismatch
Network Security in Information Security does not necessarily imply only network-related threats. Computer technology provides many ways for personal privacy to be invaded. E-mail can be intercepted by third parties and passwords can be stolen by keyloggers or shoulder surfers.
Social engineering attacks can be used for identity theft. Also, webcams placed on computers by default might capture sensitive images without the user’s knowledge. The existence of these threats reflects how vulnerable computers are compared with traditional paper documents.
If a document is lost or stolen there is no easy way for an unauthorized person to extract any information from it. Unless they have special knowledge. But if a computer is stolen not only will all its current contents be available but it will provide access to all other devices.
Information Security Principles
Information security policies define who has access to network resources. Also, who has administrative privileges, what actions are prohibited, and what actions will be monitored. Network administrators have considerable power over the security of their networks.
Since they can grant or restrict access to resources depending on their role within an organization. The combination of these responsibilities makes it especially important. So, they have a thorough understanding of the application of information security principles and knowledge of appropriate policies and procedures.
An effective information security policy should be designed to ensure that information assets are protected. That is against threats from any source at any point in time—both internally and externally. Individuals who have access to sensitive information or resources also adhere to proper information handling practices.
Wireless Network Security
Wireless Network Security is not a new term for network security. But the technology has introduced some new challenges. A wireless network is a network that enables users to connect to a computer network or the internet. That is using wireless devices, such as mobile phones or laptops.
Moreover, wireless networks are mainly used in the home. But they are becoming more and more popular in public areas. Mobile phones and computers with wireless capabilities enable people to use the internet wherever they are, without the need for fixed network cables.
What is the main difference between a wired and a wireless network? It is that on a wired network all of the connected devices share a common connection. This is (usually copper) into each device, whereas in a wireless network each device has its connection.
Usually, this is wireless to access the network. The two basic types of wireless networks are:
Wireless LANs – mostly used in homes and small businesses.
Wireless WANs – used in larger organizations to connect remote offices.
Network Security Key Error
Packet filtering routers are designed to prevent unauthorized end-user access to an organization’s networks. But they can inadvertently block legitimate traffic as well. Most organizations have a local office that is connected to the main office through a high-speed link.
This is usually referred to as the corporate backbone. The network on the opposite end of this link should be isolated from the rest of the organization’s networks. This includes the corporate backbone.
In this way, it will be easy to maintain network security between these two ends of the network.
