How to protect enterprise information assets through network security operation and maintenance?

In the digital era, enterprise information assets have become one of the most important assets. Sensitive information such as corporate core secrets, customer information, and financial information are all stored in computer systems. Therefore, protecting the security of enterprise information assets has become one of the important tasks of enterprises.

Network security operation and maintenance is an important part of an enterprise. It covers a wide range of areas, including: network device management, network defense, intrusion detection, log management, backup and recovery, etc. Currently, there are more and more means of cyber attacks, and the targets of attacks are becoming more and more diversified. Therefore, enterprises need to develop detailed and complex network security policies and measures to protect the security of their data assets. The following article will explore ways to protect corporate information assets from the perspective of network security operations and maintenance.

1. Encrypt all sensitive data

Data stored by enterprises can easily be intercepted during transmission, leading to leakage. Therefore, in order to protect the security of enterprise data assets, sensitive data must be encrypted. Common encryption methods include symmetric encryption and asymmetric encryption. Symmetric encryption is divided into DES, AES, 3DES and other algorithms. Asymmetric encryption mainly uses the RSA algorithm. When configuring the encryption method, you must ensure the strength of the encryption algorithm and the security of the encryption key, which can effectively prevent interception attacks and eavesdropping.

2. Back up data regularly

When protecting corporate assets, a very important step is to back up data regularly. Backing up your data regularly allows you to quickly restore your data in the event of events such as system crashes and data leaks. When backing up, you should pay attention to issues such as data selection, storage media, and backup frequency. The common backup frequency is once a day/week/month. Companies should choose the backup frequency based on business needs, check whether the backup data is complete, ensure that their test procedures are reliable, and should try to use offline backup methods.

3. Expired and useless data cleaning

Expired and useless data takes up storage space and brings security threats to the stored data. Therefore, enterprises should take effective cleaning measures, delete expired and useless data, and develop appropriate cleaning strategies. Before deleting data, you need to ensure that the data is backed up for data recovery.

4. Firewall and access control

Firewall is an effective means to protect network security. It can control the data flow in and out of the network through rules to prevent unnecessary access and attacks. . Access control is to limit the scope of access and operations through certain permissions, thereby protecting the security of corporate assets. Access control includes: account password protection, user rights management and other measures.

5. Intrusion Detection and Log Management

Adequate log management can provide effective protection for the security of enterprise information assets. Through log management, security incidents and information left behind can be discovered in a timely manner. Criminal almanac evidence. Intrusion detection technology quickly detects intrusions by monitoring traffic and behavior on the network so that timely processing can be carried out.

To sum up, network security operation and maintenance is a key step for enterprises to protect the security of information assets. Whether it is protecting data or protecting the security of network systems, in the process of implementing network security operation and maintenance, there needs to be an effective A comprehensive, efficient strategy to protect asset security, otherwise, even if loopholes and vulnerabilities are discovered, it will be difficult to take timely and effective measures.
