A new understanding of how to encrypt industrial computers: host reinforcement application

Mainframe reinforcement

Recently, the concept of host reinforcement has been heated , The function of host reinforcement is also being concerned by those who are committed to server security .

So what is host reinforcement ？

Host reinforcement is actually a security mark for the system 、 Access control and other multi-layer and three-dimensional protective measures , Make up for operating system defects .

It can be understood as putting a lock on the main machine , Redefine the functions of each module of the operating system , Build an independent identity authentication system , When anti-virus software 、 When the firewall doesn't work , The host can still be protected , Prevent viruses and Trojans from invading , Prevent core data from being peeped 、 Be destroyed 、 Be tampered with 、 Stolen ！ By guarding against external attacks , Prevent internal active disclosure , Solve abnormal behaviors such as unauthorized access , Make up for the security shortcomings of traditional information security solutions in the host layer , Improve the overall security protection ability of the operating system .

To make a long story short , Host reinforcement and anti-virus software are two completely different concepts , They are complementary , Not a substitute relationship .

The core points of host reinforcement ：

1、 System reinforcement

Lock the debugged system , Become a trusted system .

In a trusted system , Illegal procedure 、 Scripts can't run . And it will not affect data access .

Even if the system has vulnerabilities , Even administrator privileges are lost , This trusted system is secure .

2、 Program reinforcement

The executable program is signed by trusted signature 、 Start the script in real time hash Value verification , If the verification fails, the startup is rejected , And trusted programs cannot be disguised .

3、 Document reinforcement

Protect files of the specified type from tampering .

4、 Disk encryption

Create a safe sandbox , The sandbox is isolated from the outside , Encrypt the data in the sandbox , Ensure that the data can only be used under the premise of effective authorization management , To be decrypted . If there is no authorization , Even administrators cannot copy and use this data , Even system cloning does not work .

5、 Database hardening （ Structured data ）

first floor ： Database files are forbidden to be accessed and tampered with by unfamiliar programs . Ensure database file level security .

The second floor ： Database port access trusted filtering , Only business programs are allowed to connect to the database port , At the end of the connection string IP+ port + In the account password , Append process identification .

The third level ： Database connection SQL Intelligent filtering of text , Prevent critical data from being retrieved and accessed , Prevent the data in the database from being accessed illegally , Prevent dangerous operations of database forms .

Host reinforcement application scenario ：

1、 Protect enterprise server security . Server anti blackmail virus 、 Trojan horse 、 mill 、 Data tampering, etc .

2、 Host data anti disclosure protection . Without affecting the normal operation and maintenance of the host , Encrypt and protect sensitive data , Prevent core data from being stolen or tampered with .

3、 Business system host （ Including professional operating system embedded in the equipment ） Best state locking , Reduce viruses through process whitelist control 、 Number of illegal programs running , Greatly reduce the operation and maintenance of the host .

4、 Disk encryption , Even if the server is stolen , The hard disk was removed , The protected data is still encrypted .

Which host reinforcement brands are worth recommending ：

At present, several brands that have done well in the field of host reinforcement are known in the market ：

1、 Xinda's MCK Mainframe reinforcement .

2、 Wisteria cloud security .

3、 Luoan Technology .

4、 wave .

5、 Anheng .

6、 Convinced .

7、 Tian Rong Xin .

 

In no particular order . Personal recommendations MCK Strengthen the host , Because what our company buys is MCK Mainframe reinforcement . It is said that their sandbox encryption is also an old brand in the industry , You can rely on .
