1. What are Information Leakage Countermeasures?
Information leakage countermeasures are measures to prevent internal confidential information from leaking outside the company. Without countermeasures, corporate information is more likely to leak externally due to cyberattacks such as viruses and malware, or information leaks due to human error.
To reduce the risk of information leakage, it is important to create internal guidelines to clarify how to handle information and to provide information security training to employees. In addition, introducing information leakage prevention software that can prevent leakage even in the event of cyberattacks or human error is also an effective countermeasure.
1-1. Causes of Information Leakage
There are two causes of information leakage: internal and external factors. Internal factors include accidental misoperation such as mistaking the file attached to an email, loss or misplacement of important documents, and management errors that allow anyone to view confidential information. In particular, leaks due to misoperation are common, and it is necessary to improve employee awareness and strengthen systems with leakage prevention measures.
External factors include unauthorized access exploiting system vulnerabilities, virus infection, and eavesdropping on email content. Since malicious third parties are the cause, security measures are required to prevent external access.
2. 10 Recommended Information Leakage Prevention Software
Information leakage prevention software is software that takes measures to prevent internal confidential information from leaking outside the company by providing functions such as data export prevention and access control. There are two types: products that specialize in one function and products that comprehensively have multiple functions.
Here, we will explain the features of representative information leakage prevention software.
2-1. AssetView
AssetView is an IT asset management tool that can provide a wide range of security measures, including internal fraud and external attacks. It reduces the operational burden of security by integrating management servers and consolidating management tools.
It has many functions such as malware infection countermeasures and data leakage countermeasures, but you can select only the necessary functions. You can also purchase only the number of licenses you need, which can reduce costs. You can choose from two environments: on-premises for self-operation and cloud for using services via the Internet.
2-2. Measures with Security Software
Basic IPCC is an information leakage prevention tool for Windows that prevents unauthorized Internet connections. It restricts connection destinations when using a PC outside the company, and allows you to protect your company’s security policies while outside the company. It is possible to ensure safety by having employees comply with the rules when teleworking.
Specifically, it enhances security by limiting network connections to specific areas and preventing PC Internet connections using smartphone data communication. It is also possible to prevent information leakage through virus infection countermeasures.
2-3. Crossway/Data Bridge
Crossway/Data Bridge is a security device that connects terminals with cables and transfers data one-way. There are two types: a “manual type” that transfers data one by one without omission, and an “automatic type” that automatically transfers large amounts of files.
To prevent information leakage accidents from transferred files, virus checks and sanitization of files are performed. The data on the device is automatically deleted when the device is turned off, reducing security risks due to forgetting to delete data. A 2-week free trial is available on the website.
2-4. EXO Security
EXO Security is a tool that provides a wide range of security measures, including malware countermeasures, vulnerability checks, personal information encryption, and blocking access to malicious sites. Artificial intelligence and cloud analysis technology detect anomalies in real time.
In addition, it is possible to manage the blocking and permission of device connections such as USB memory, and prevent files from being taken out. The simple and easy-to-use management screen allows you to monitor all PCs in the company, reducing the burden on administrators.
2-5. FENCE-G
FENCE-G is a tool that controls data export via devices (USB memory, CD/DVD, etc.), network eavesdropping, and unauthorized access. It prevents information leakage by restricting PC operations and restricting access to sites unrelated to work.
It is also possible to encrypt information and distribute confidential documents in a way that does not leak to third parties. It also provides support for formulating security policies to strengthen the company’s security level.
2-6. Intersafe ILP
Intersafe ILP is a series of information leakage countermeasures products that cover various security functions. It consists of five functions: device control, file transfer between networks, network separation, automatic file encryption, and security USB creation, and you can freely combine the necessary functions.
In addition to the five basic functions, three functions can be added as options: file export application, file sanitization, and personal information detection in files. A 30-day free evaluation version is available, and it can be installed on-premises or in the cloud.
2-7. L2Blocker
L2Blocker is a security countermeasure software that detects and eliminates unauthorized PCs by installing a dedicated sensor in the company’s LAN. It can also provide cyberattack countermeasures, but it focuses particularly on preventing information leakage due to fraud from within the company.
It can centrally manage internal terminals and automatically block access from terminals that are not on the permission list. Since only internal terminals can connect to the network, it blocks the connection of personal items such as smartphones, preventing virus infection and information leakage.
2-8. Data Erasure
Data Erasure is a tool specializing in erasing files and data stored on a PC. It erases data using one of three methods: “physical destruction” that destroys the HDD, etc., “magnetic erasure” that applies a strong magnetic field, and “software erasure” that overwrites random numbers.
Since data is physically erased, it is impossible to restore data with restoration software. It is a suitable tool for recycling and reusing PCs. It also supports data erasure for feature phones and magnetic tapes, which are increasing in the number of disposals.
2-9. Hakken-den
Hakken-den is software that monitors device connections, printer output, and email attachments to prevent information leakage to the outside. If a USB memory not registered in the list is connected, it will be forcibly locked and shut down or logged off.
It centrally manages user operation history, and if there is any fraud, a warning alert is displayed and a notification is sent to the administrator by email. A 15-day free trial is available, and you can try the functions of Hakken-den.
2-10. Hibun
Hibun is a tool that comprehensively performs security countermeasures and IT asset management. It has been providing services for over 25 years and has been ranked No. 1 in market share for 17 consecutive years since 2004. The malware countermeasures function has won awards at competitions and is a highly effective tool.
Since the tool is developed in-house, support during implementation and operation is thorough. Even if a security-related problem occurs within the company, a dedicated expert will quickly respond to resolve the problem.
Summary
It is important to take information leakage countermeasures to prevent personal information and confidential information handled by companies from leaking to the outside. There are two types of causes of information leakage: internal factors and external factors. The former can be prevented to some extent by establishing guidelines within the company and providing security education to employees. On the other hand, strong measures such as security software are necessary to prevent information leakage due to external factors such as unauthorized access.
There are various types of information leakage prevention software, from those with a single function to those with a wide range of security systems. It is important to choose a type of product that suits the company’s situation and the important data it handles.
