How to avoid serious network security incidents?

Technological development has increased cybersecurity risks. From the sharp increase in the number of online frauds to the increasing number of human error issues, critical and sensitive information of enterprises is under greater threat. What’s more, some serious cybersecurity risks will also spread life safety of personnel.

Although absolute security protection does not exist, enterprise organizations must make every effort to avoid serious security incidents that may affect the survival and development of enterprises. With the active support of national policies and regulations, more and more enterprises are constantly improving their security awareness, but there are still some deficiencies in responding to some large emergencies. This article summarizes the major network security incidents that some enterprise organizations may face, and gives corresponding protection policies, hoping to provide more targeted security protection experience and knowledge for enterprise organizations in case of emergencies.

01 Continuously strengthen security controls

In order to solve the problems of cloud leakage and system exposure caused by configuration problems, enterprises must first increase their attention to configuration accidents and configuration problems.

Configuration incidents are varied, some are genuine errors or oversights (two-factor authentication is not required to access sensitive resources), some are systems that lack adequate protection against social engineering attacks, and some are caused by organizational ignorance of deliberate spelling Attacks such as error attacks.

There are many solutions to this problem. Organizations can set more reasonable default permissions, such as all content is private by default, and explicit steps must be taken to make certain content publicly visible before it can be used; it can also set unique strong passwords for cloud services, and Use two-factor authentication to avoid security incidents such as Colonial Pipeline attacks due to compromised passwords; in addition, organizations can also use vulnerability scanning and Internet scanning tools such as Shodan and Censys to conduct regular assessments of the company’s potential attack surface.

02 Maintain reliable data and system backups

Ransomware attacks may bring economic losses to enterprises, and are a relatively serious type of attack. However, enterprise organizations usually have a fluke, and few enterprises actively customize protection schemes to deal with such attacks. Although some enterprise organizations have a large number of old software products to deal with ransomware attacks, they are full of loopholes. Therefore, enterprise organizations should recognize the cost of upgrading and maintaining these old system products, and the business interruption and damage caused by ransomware attacks. Finances are more important than losses. While many industry players believe that ransomware attacks don’t necessarily cause economic problems, for corporate organizations such as hospitals, it’s a matter of life and death. Although such attacks cannot be completely avoided, enterprise organizations can respond to attackers by backing up and implement VM solution to backup and protect data, which can ensure that key business processes can be quickly restored after an attack occurs, and further reduce the risk of ransomware attacks.

03 Data classification and classification management

Due to the huge amount of all data required to keep the business running smoothly, it is difficult and expensive to back up all of them, and data theft and ransomware attacks may only steal important and sensitive data in the enterprise. Therefore, there is no point in backing up large amounts of ordinary data. And in the event of a data breach and ransomware attack, it’s even more detrimental to the company. Therefore, the best preventive measure is to conduct a thorough analysis of existing data, make backups of important data, delete unnecessary data or transfer less important data. This way, organizations can protect the data that really matters, even if systems are compromised.

04 Threat Alert Automated Response Management

In daily work, the noise of massive threat alerts is also a problem that has always plagued enterprise organizations. Automation technology can help in this problem. Organizations can configure automated tools that can prioritize threat alerts to determine the importance of different alerts. Automated tools with contextual analysis capabilities have advantages in classifying and grading threat intelligence and automating response capabilities.

05 Strengthen employee safety awareness

In addition to doing practical precautions, it is also very important to ensure the safety awareness of all employees in the enterprise organization. The best way to protect yourself is to raise the cyber security awareness of all employees of the company while doing practical work.

In fact, many of the protective measures to ensure corporate and personal network security are very basic, such as setting strong and unique passwords for important websites, using two-factor authentication, ensuring that software and operating systems are up-to-date, avoiding clicking on suspicious or illegal links, doing great in backup etc.

However, in the face of the above-mentioned complex work environment on a large scale, it is not easy to be able to do a good job of security protection consistently. At this time, improving the awareness of all employees of the enterprise organization can play a huge role. Make employees more proactive in cooperating with security measures. Even though security inspections, routine audits, etc. may seem costly and tedious, if the organization is a potential target of the above-mentioned attacks, you can understand the importance of building good employee security awareness.
