1. Understand the common ways of information security leakage
Information security leakage is an issue that needs to be highly valued, and it may occur in many ways. The following are several common ways of information security leakage:
1). Leakage during data transmission
When you transmit data online, such as sending emails or shopping online, if the data is not encrypted, it is like you are talking loudly in public, and anyone can eavesdrop.
Hackers can use special tools to intercept these unencrypted data packets and obtain your personal information, such as account numbers, passwords, etc. Therefore, it is crucial to ensure the encryption of data transmission.
2). System or software vulnerabilities
Whether it is a computer, mobile phone, or other smart device, their operating systems and installed software may have vulnerabilities. These vulnerabilities are like a door lock that is not locked properly at home.
Hackers can easily use these vulnerabilities to enter your system, just like a thief entering your home. Therefore, timely updating and patching of system vulnerabilities is an important means of protecting information security.
3). Physical access and operational errors
If you accidentally lose a storage device, such as a USB flash drive, hard drive, etc., or lend these devices to untrustworthy people, your data may be leaked. In addition, employees or third parties may also cause data leakage due to negligence or improper behavior during operation.
Therefore, it is very important to strengthen the security management of physical equipment and train employees to improve security awareness.
4). Risks in the supply chain
In the entire supply chain, from suppliers to final products, any problem with any link may lead to data leakage.
For example, if the supplier’s data security protection measures are not in place, hackers may steal your data by attacking the supplier. Therefore, companies need to choose trustworthy suppliers and establish a secure supply chain management system.
In summary, there are many ways for information security to be leaked, but as long as we strengthen our awareness of data security and take necessary security measures, we can effectively reduce the risk of leakage.
2. Preventive steps before purchase
It is crucial to prevent information security leaks before purchasing products or services. Here are a few key preventive steps, especially when choosing suppliers and products:
1). Choose reliable suppliers
- Research the market reputation of suppliers:
Before purchasing, learn about the reputation of suppliers in the market by checking customer reviews, industry reports, and news articles. This will help you determine whether the supplier is trustworthy.
- Investigate historical performance:
Check the supplier’s past project cases and customer feedback to understand its past performance in information security. If the supplier has a record of multiple security breaches, then you may need to reconsider whether to choose them.
- Evaluate security measures:
Ask suppliers for specific details about their information security measures, including how they protect data, prevent unauthorized access, and respond to potential security threats.
- Give priority to suppliers with information security certifications:
Choose those that have passed ISO 27001, SOC 2, or other relevant information security certifications. These certifications demonstrate the supplier’s professionalism and compliance in information security.
2). Understand product security features
- Ensure the product has key security features:
Before purchasing a product, make sure it has key security features such as data encryption, authentication, and access control. These features can protect your data from unauthorized access and leakage.
- Ask about security updates and maintenance policies:
Understand how the supplier provides security updates and maintenance services for the product. A responsible supplier will regularly release security patches and updates to fix known security vulnerabilities.
- Consider the product life cycle:
Understand the product life cycle, including whether it is about to become obsolete or whether there are plans for major updates. Choose products that have long-term support and update plans to ensure that your information security is continuously protected.
By following these preventive steps, you can reduce the risk of information security breaches before purchasing a product or service.
Remember, choosing a reliable supplier and understanding the security features of the product are key to protecting your data and business security.

3. Security measures during the installation and configuration phase
During the installation and configuration phase, ensuring information security is a key part of building a solid defense system. Here are a few simple but critical security measures to help you protect your physical devices and network environment:
1). Physical security protection
- Security layout of display screens:
First, place the display screen in a location that is not easily touched or peeped by sight, such as high up or in a corner, which can reduce the risk of unauthorized access.
Second, physical barriers, such as installing a protective cover or fixing a bracket, can be used to add an extra layer of protection to the display screen.
- Strict access control:
To ensure that only authorized personnel can operate the display screen, you need to establish a strict access control mechanism.
This may include using access cards, password locks, or biometrics to limit access to specific areas. At the same time, authenticate anyone who attempts to access the display screen to ensure that they have legal authority.
2). Network security reinforcement
- Strong password policy:
Set complex and unique passwords for your network devices, systems, and applications. Avoid using easy-to-guess or common passwords, and change passwords regularly to reduce the possibility of being cracked.
Remember, a good password should contain a combination of uppercase and lowercase letters, numbers, and special characters.
- Firewall and intrusion detection:
Enabling a firewall can block unauthorized access while limiting unnecessary network traffic. In addition, installing an intrusion detection system (IDS) can monitor network activities in real time to detect and respond to any suspicious behavior in a timely manner.
These systems automatically analyze network traffic, identify potential attack patterns, and take appropriate defensive measures.
- Network isolation:
Physically or logically isolate the control network from the public network to prevent malicious traffic from spreading in the internal network.
This can be achieved by dividing different VLANs (virtual local area networks) or using physical isolation devices. By isolating the network, you can limit the communication between different areas, thereby reducing the risk of data leakage.
3). Additional recommendations
- Regular backup:
Regularly back up important data to ensure that it can be quickly restored in the event of an accident or data loss. This helps to reduce the potential losses caused by data loss.
- Software updates:
Timely update operating systems, applications, and security patches to fix known security vulnerabilities. Keeping software and systems up to date is key to preventing new threats.
- Security audits:
Regularly conduct security audits and risk assessments to identify and fix potential security weaknesses. This helps ensure that your network and systems are always in the best security state.
By implementing these security measures, you can greatly reduce the risk of information security leaks during the installation and configuration phase.
Remember that information security is an ongoing process that requires regular evaluation and adjustment of strategies to cope with the ever-changing threat environment.
4. Best practices in daily operations and maintenance
In the details of daily operations and maintenance, ensuring information security is a complex and meticulous task, which requires us to adopt a series of practical and humane best practices. The following are some practical suggestions to improve the level of information security, which are easy to understand and implement:
1). Refined permission management
- Implement the principle of least privilege:
In daily work, we should follow the principle of “knowing what is necessary and using what is necessary”; that is, each employee or system component is only granted the minimum privileges required to complete their duties.
The advantage of this is that even if an account is illegally hacked, the damage that the attacker can cause will be limited to the minimum scope.
- Regularly review the permission setting:
With the changes in team structure and the adjustment of employee responsibilities, the permission setting also needs to keep pace with the times.
Therefore, we should regularly review the allocation of permissions to ensure that each employee has permissions that match their current responsibilities and revoke permissions that are no longer needed in a timely manner.
2). Improve employees’ awareness of information security
- Carry out information security training:
Information security is not just a matter for the technical department; it is related to the vital interests of every employee. Therefore, we should organize information security training activities regularly to enhance employees’ awareness and prevention capabilities of information security through vivid cases and practical skills.
- Strengthen the operation specifications of display screens:
As an important window for information display, the operation specifications of display screens should not be ignored.
We should clearly convey to employees the importance of correctly operating display screens, such as avoiding displaying sensitive information in public places, regularly cleaning up residual traces on the screen, etc., to reduce information security risks caused by improper operation.
3). Keep the system updated and maintained
- Timely update of firmware and operating system:
Firmware and operating system updates often contain important security patches and performance optimizations, which are crucial to improving system security. Therefore, we should pay attention to and install these updates regularly to ensure that the system is always in the best condition.
- Regularly perform system security checks:
System security checks are an effective means to discover potential security issues. We should regularly use professional security tools to conduct comprehensive inspections of the system, including vulnerability scanning, log analysis, network traffic monitoring, etc., in order to promptly discover and repair potential security risks.
In summary, by implementing refined permission management, improving employees’ information security awareness, and keeping the system updated and maintained, we can effectively reduce the risk of information security leaks and safeguard the steady development of the organization.
These measures are not only easy to understand, but also easy to implement. They are basic skills that every information security guardian should master.
5. Build a flexible emergency response system
In the face of information security challenges, a flexible and practical emergency response system is like a solid line of defense that can provide us with strong support at critical moments. Here are a few key points on how to build such a system:
- Design clear response steps:
Imagine what you would do if data was leaked or the system suddenly crashed. Our emergency response plan is to solve this problem.
It should contain a series of clear and specific response steps, from the moment the problem is discovered to the summary and reflection after the problem is solved, and each step should have clear guidance.
- Make sure every employee knows:
The plan is well formulated, but if it is not understood by everyone, it is equivalent to a waste. Therefore, we need to ensure that every employee is familiar with the content of the plan, knows what role they should play in an emergency, and how to cooperate with the team to respond.
