Network security has always been the focus of everyone's attention. In today's digital age, the problem of network security is becoming more and more severe, and network attackers use more complex and advanced attack methods in an attempt to invade and endanger our computer network from various angles. Therefore, we must develop a comprehensive network security strategy in order to better protect our network and data assets. In this article, we will discuss how to deal with the changing threat environment and propose an effective cybersecurity strategy.
Chapter 1 : Evolution of Cybersecurity Threats
Network security threats are no longer simple virus and Trojan horse attacks, it has become more complex and advanced. Today's attackers use more sophisticated tools and techniques, and more flexible attack methods. Here are some of the most common cybersecurity threats:
1. Malware: Malware can include viruses, Trojans, spyware, adware, etc. Attackers can use malware to break into computer networks and obtain sensitive information.
2. Phishing: Phishing is an attack method in which attackers use social engineering methods to trick victims into submitting personal information or login credentials.
3. DDoS attack: DDoS attack means that the attacker sends a large number of data packets to the target server, causing it to fail to work normally.
4. Wireless network attack: Wireless network attack refers to the attacker exploiting the vulnerability of the wireless network to invade the target network or steal data by monitoring network traffic.
Chapter 2 : Formulation of Cyber Security Strategy
In response to ever-changing cybersecurity threats, it is critical to develop a comprehensive cybersecurity strategy. Here are some suggestions that can help organizations develop an effective cybersecurity strategy:
1. Develop a clear policy: Organizations need to have a clear policy for cybersecurity that all employees understand and follow. Strategies should include education and training, security vulnerability remediation, network intrusion detection, and more.
2. Invest in cybersecurity: Enterprises need to invest sufficient resources in cybersecurity, including software, hardware, manpower and training. These resources will enable businesses to respond quickly and effectively to cybersecurity threats.
3. Continuous monitoring: Enterprises should continuously monitor the network, look for anomalies, and establish a response plan. This requires the use of security tools to monitor network traffic, access controls, file activity, and more.
4. Conduct regular drills: Drills can check the effectiveness of network security policies. Enterprises should regularly conduct network security drills to test employees' ability to deal with threats and improve network security strategies through practical simulation drills.
5. Compliance with regulations and standards: Enterprises need to comply with relevant regulations and standards, such as PCI-DSS, HIPAA, GDPR, etc., to ensure network security and data privacy.
Chapter Three : Security Awareness Training
The network security of an organization is closely related to the security awareness of employees. Therefore, conducting security awareness training is crucial to developing a cybersecurity strategy. Here are some suggestions:
1. Regular Training: Cybersecurity awareness training should be a regular activity to ensure employees stay on top of cybersecurity issues.
2. Classified training: Different types of employees may require different types of training. Management should receive a higher level of training than other employees to understand the organization's cybersecurity policy.
3. Interactive training: Instead of just displaying training materials as lectures, it is better to carry out interactive training, such as discussing actual cases as examples.
4. Mandatory training: Businesses need to ensure that all employees have received cybersecurity training. Employees must undergo mandatory training to ensure that all employees understand cybersecurity policies and best practices.
Chapter Four : Network Security Technology
The right technology is also very important when developing a cybersecurity strategy. Here are some suggestions:
1. Use the latest security software: Security software must be the latest version, including anti-virus software, firewall, intrusion detection system, etc.
2. Use encryption: Businesses must use encryption to protect sensitive information. Encryption technologies include SSL, TLS, SSH, etc.
3. Multi-factor authentication: Use multi-factor authentication to increase your network security. For example, use passwords, tokens, and biometric authentication when logging in.
4. Network isolation: Network isolation prevents attackers from roaming in the network. Businesses can use a virtual private network (VPN) or network isolation technology to secure the network.
Chapter Five : Practical Cases
Finally, we look at some enterprise practice cases to deepen the understanding of network security strategy.
1. The data breach of the target company
The target company is a large retailer in the United States. In 2013, the company suffered a major data breach that affected the credit card information of more than 40 million customers. The company said in a report that hackers used credentials from a third-party vendor to log into the targeted company's network and then accessed customers' credit card information. This incident reveals the importance of supplier management, and enterprises should review suppliers' security measures and implement data security protocols to ensure that suppliers do not become security vulnerabilities for enterprises.
2. Yahoo's data breach
Yahoo’s exposure in 2016 that some 500 million accounts had been hacked resulted in huge financial and brand damage. It was later found that the incident was caused by some insecure passwords and encryption techniques. This incident revealed the importance of security awareness training to ensure employees use secure passwords and understand best practices for password management.
3. Malicious attacks by internal employees
Within a company, employees can also be security holes. A disgruntled employee could steal confidential data, compromise a network, or knowingly leak information. Businesses should revoke access when employees leave and review employee cyber activity to prevent malicious attacks.
The cybersecurity environment is constantly changing, and organizations need to develop a robust cybersecurity strategy to address evolving threats. Organizations should always stay on top of the latest threat intelligence and regularly review the effectiveness of their cybersecurity policies. At the same time, enterprises should also conduct security awareness training and use the latest security technology to protect the network. Through these measures, enterprises can ensure their network security and reduce the risk of being attacked by the network.
