How to control intranet security?

Intranet security is an aspect that cannot be ignored in enterprise information security. I often hear network security personnel say that it is difficult for external hackers to enter the corporate intranet, but accidental or malicious operations by internal employees account for the majority of corporate information leaks. Enterprises need to control intranet security to ensure corporate information security and property security.

1. Understanding intranet security threats

Before controlling intranet security, we need to understand the threats to intranet security. Intranet security threats mainly come from internal employees and external hackers.

Threats to internal employees mainly include:

1. Unexpected operations

Negligence or improper operation by internal employees, such as misoperation, operational errors, etc., will Leading to threats to the security of the internal network.

2. Data leakage

Internal employees leak data intentionally or unintentionally, such as accidentally sending data emails to the wrong objects, not encrypting files when transferring, etc., which will cause Intranet security issues.

3. Use of authority

Internal employees often have certain permissions. If employees take advantage of their permissions and operate the company's internal systems and data beyond their authority, it is also an intranet security threat.

External hacker attacks mainly include:

1. Network attacks

Network attacks are attacks carried out by hackers against external systems within the corporate network. Once hackers break into external systems, the security of the enterprise's intranet will also be threatened.

2. Physical attack

Hackers can also use physical attacks, such as inserting Trojans on corporate internal network ports, entering the corporate intranet and controlling the network through physical attacks.

3. Social attack

Social attack refers to hackers obtaining internal employee information through social engineering and using this information to carry out attacks. For example, attack through emails, text messages or email attachments to obtain confidential information.

2. Control intranet security measures

After understanding the intranet security threats, how to control intranet security? The following are measures to control intranet security:

1. Setting access permissions appropriately

Setting access permissions for employees within an enterprise is crucial to intranet security. In order to prevent employees from exceeding their authority and prevent hackers from using their authority to attack, companies should strictly control the access rights of each employee.

For example, employees' work content and positions can be classified and given different access rights to ensure that employees can only view and operate information related to their work.

2. Install network security equipment

In response to attacks by internal employees and external hackers, enterprises need to install network security equipment, screen and monitor network traffic, and protect the security of the corporate intranet .

For example, enterprises can install network security equipment such as firewalls, intrusion detection and anti-virus software to monitor and analyze network traffic in real time, identify and block suspicious traffic, and ensure the security of the corporate intranet.

3. Strengthen employee education and management

Employees of an enterprise are an important part of intranet security. Adequate intranet security education and management for employees can effectively improve employee safety awareness and prevention capabilities.

For example, employees can be regularly trained and educated on network security knowledge to guide employees to develop safe operating habits and prevent email fraud and other online fraud.

In addition, before employees leave the company, they should be clearly informed that they no longer have access rights within the company to avoid employees from exceeding their authority.

4. Back up enterprise data regularly

Enterprise data is the property of the enterprise, and backing up data is one of the effective measures to ensure the security of the enterprise intranet. Regular backup of corporate data can not only prevent data loss due to improper employee operations, system failures, natural disasters, etc., but can also deal with data loss caused by hacker attacks and quickly restore corporate business operations.

You can choose to back up data online or offline, such as copying data to the enterprise's local or cloud backup system. For data backup that requires a higher level of security, offline methods can be used, such as writing the data to CDs, DVDs, Blu-ray discs, etc., and storing it in a safe place.

Conclusion

Intranet security is an important part of enterprise information security. Enterprises need to control intranet security and protect corporate property and user information security. Enterprises can take control of corporate intranet security by properly setting access permissions, installing network security equipment, strengthening employee education and management, and regularly backing up data.
