Security Problem

this article from the various security threats facing the computer network, systematically introduces the network security technology. And in view of the campus network security issues, firstly analyzes the hidden dangers to the safety of network system in colleges and universities, and then from the build two aspects of security defense system and strengthen the safety management design of the campus network security policy. This paper study, the first thing I learned the main threat to the network security problem, and use the knowledge of security network security problems are analyzed. Secondly, based on the research of the network technology, campus network will also be faced with the security threat. Finally, the idea of established with P2DR model to establish campus network security defense system. And it is concluded that the building of a set of effective network security defense system is the solution Campus network main threats and hidden trouble of necessary ways and measures.

Firewalls are an essential component of the Internet and enterprise network security policy enforcement today. The configurations of enterprise firewalls are typically rather static. Even if client’s IP addresses can be dynamically added to the packet filtering rules, the services allowed through the firewall are commonly still fixed. In this paper, we present a transparent firewall configuration solution based on mobile cryptographic identifiers of Host Identity Protocol (HIP). HIP allows a client to protect the data transfer with IPsec ESP, and supports dynamic address changes for mobile clients. The HIP-based firewall learns the identity of a client when it communicates with the server over HIP. The firewall configures the necessary rules based on HIP control messages passing through the firewall. The solution is secure and flexible, and introduces only minimal latency to the initial HIP connection establishment.

Network security policy automation enables enterprise security teams to keep pace with increasingly dynamic changes in on-premises and public/hybrid cloud environments. This chapter discusses the most common use cases for policy automation in the enterprise, and new automation methodologies to address them by taking the reader step-by-step through sample use cases. It also looks into how emerging automation solutions are using big data, artificial intelligence, and machine learning technologies to further accelerate network security policy automation and improve application and network security in the process.

Good Policy

In the last chapter, we discussed the basics of network security. Among the issues that we briefly touched on are the techniques and best practices that are currently being used by many security personnel in a variety of networks that make up the communication infrastructure. In this chapter, we are going to start with what is considered to be the most basic of all security techniques—security.policy. We will discuss several issues about security policy, like what constitutes a good policy and how to formulate, develop, write implement, and maintain a security policy.

Emerging Issues

One of the emerging issues in the field of digital crime and digital forensics is corporate preparedness in dealing with attacks on computer network security. Security attacks and breaches of an organization’s computer network can result in the compromise of confidential data, loss of customer confidence, poor public relations, disruption of business, and severe financial loss. Furthermore, loss of organizational data can present a number of criminal threats, including extortion, blackmail, identity theft, technology theft, and even hazards to national security. This chapter first examines the preparedness and response of three southwestern companies to their own specific threats to corporate cyber-security. Secondly, this chapter suggests that by developing an effective security policy focusing on incident detection and response, a company can minimize the damage caused by these attacks, while simultaneously strengthening the existing system and forensic processes against future attacks. Advances in digital forensics and its supporting technology, including intrusion detection, intrusion prevention, and application control, will be imperative to maintain network security in the future.
