The problem of inadequate network security technology is increasing, and it is not surprising for network professionals. A new survey of 343 cybersecurity professionals released by the Information Systems Security Association (ISSA) and the market research company Enterprise Strategy Group (ESG) revealed that not only 70% of respondents indicated that cybersecurity technology is insufficient. Enterprises have caused an impact, and 62% said that their companies can't provide enough training for their network security professionals. This is a full 10 percentage points higher than the same survey conducted by ISSA last year. Of particular note is the lack of safety analysis and investigation techniques, and the lack of application security technology is the most worrisome (31%), followed by cloud computing security technology (29%). The ISSA survey summarizes the five major cybersecurity investment pitfalls that companies are most vulnerable to: 1. Network security is inconsistent with corporate goals: Respondents suggested that the most beneficial measures companies can take are increasing the goals and standards for IT and corporate executives, and vice versa (43%). 2. No repeatable process was developed: Respondents stated that one of the two most severe cybersecurity issues was the reduction of manual and informal processes (28%). The second big benefit they suggested was to document and document all cybersecurity processes (41%). 3. Uninvested training: The third most useful measure suggested by respondents was to increase investment in training and education at all levels, from non-technical employees, IT and cybersecurity teams, to executive management. 4. Failure to provide proper training: Respondents currently expect that specific training courses (76%) and professional development agencies (71%) will provide knowledge, skills, and capabilities (KSA) rather than safety certifications. 5. In the future plans and strategies did not take into account the continuing technical deficiencies: Respondents stated that the biggest cybersecurity issue is that the network security staff is understaffed (29%) relative to the size of the company. Companies need to develop active plans to recruit IT talent, especially those with experience in IT operations and network technology. Although this is currently a research conducted by foreign institutions on the market, it also has some reference value for the current domestic market situation. As a whole, we have the following suggestions for the network security of domestic enterprises: 1. Enterprises should pay full attention to the importance of network security and increase investment in network security, including professional training of security personnel, deployment of security devices, and deployment of monitoring systems. In today's era, the technical threshold and attack cost of cyber attacks are getting lower and lower, and lawbreakers can easily obtain various attack tools on the Internet. The road to corporate cybersecurity is a long way to go. In August 2016, the mysterious hacking team known as the "shadow broker" surfaced for the first time in the United States. Shadow brokers claimed through social platforms that they had breached the arsenal of the "formula organization" of the hacking organization under the US Security Agency. It stole the hacking tools of the U.S. Security Agency and data samples obtained during cyber espionage and tried to auction some of the hacking tools and data on the Internet. However, in April of this year, shadow brokers disclosed the hacking kits of NSA organizations that provide services specifically for spying abroad. These include WannaCry's Windows vulnerability, which was used by hackers to infect two high-profile ransomware attacks. So far, the identity of the shadow broker is still unknown. However, the organization has not disclosed all of the leaked U.S. security agency’s hacking tools. Once open, the consequences could endanger billions of software users. 2, The core of enterprise network security is to protect the security of enterprise data. It can be considered and considered from the following aspects: l Protect corporate networks from intrusions by deploying border security protection, email security protection, Internet security protection, web application security protection, and terminal security to effectively and proactively protect enterprise data. l Verify that the data is legal when leaving the enterprise by deploying a data leak prevention solution; l Through the data backup solution, the integrity of enterprise data can be guaranteed, and data loss due to various reasons can be avoided. Through the above strategies, you can effectively protect and protect enterprise data security from all aspects of the attack. Barracuda has a variety of solutions for enterprise data security that can be applied to all aspects. 3. There is no doubt that the future will be a cloud era. And cloud security is totally different from traditional security. More and more companies will also migrate to the cloud. Cloud security will also become a top priority. The Barracuda Cloud Fusion Firewall is designed to provide network and application security for both public and hybrid cloud environments. These solutions provide cloud-specific capabilities, including metering and billing, API support for the DevSecOps team, full mesh connectivity, and scalability to help companies align security with cloud deployment. Companies seeking public cloud scalability and automation benefits should require cloud-convergence firewall capabilities to include: l Have a well-structured, converged public cloud that integrates directly with the public cloud infrastructure, provides API integration for DevOps tools and automated workflows, and can be centrally managed in a hybrid environment. You can still provide users with all the advantages of public clouds without affecting their security. l Supports cloud-specific applications - Supports unique cloud requirements, including horizontal scalability, distributed policy sets, full mesh connections, and traffic management throughout. Meeting these requirements enables customers to take full advantage of cloud automation in deployment, autoscaling, high availability, networking, and monitoring. l Can match customers in the cloud consumption model provides a license that allows customers to deploy security based on the current public cloud consumption model. 4. Finally, after investing in network security, enterprises still need to pay attention to regulating the company's security management process. At the same time, they must pay attention to the training of employees' network security knowledge in order to ensure that a comprehensive network security system is established in many aspects.
