Although the spread of the internet has made information management more important than ever, there have been many cases of information leakage due to delays in response. When it occurs, not only is the organization\u2019s reputation tarnished, but it may also result in claims for damages and other problems that could affect the continued existence of the business.<\/p>\n\n\n\n

To remove the above risks, it is important to take measures in advance. This article therefore explains the key points of information leakage countermeasures and the main causes of their occurrence.<\/p>\n\n\n\n

Companies manage a great deal of highly confidential information, and once leaked, the consequences are immeasurable. It may result in loss of trust from business partners and payment of large amounts of compensation for damages. To prevent such a situation, stay alert against the factors as follows.<\/p>\n\n\n\n

Countermeasures for Employees<\/h3>\n\n\n\n

Develop guidelines and rules<\/h4>\n\n\n\n

In order to prevent human errors, each organization has responsibilities to develop and apply company-wide guidelines and rules. The policy indicated by management and the operational issues in the field should be reconciled from both sides. The templates produced by SANS will be a big help when developing them.<\/p>\n\n\n\n

Reference: Security Policy Templates\uff5cSANS<\/a>\"\"<\/p>\n\n\n\n

Conduct training<\/h4>\n\n\n\n

Information security training plays an important role to increase employees\u2019 knowledge and bring security awareness to them. Human errors are the most common factors of information leakage, and regardless of the divisions or positions, it is important to tell all employees about the risks, which will be the shortest way to avoid damages toward your organization.<\/p>\n\n\n\n

Lock device and location<\/h4>\n\n\n\n

Losing digital devices is terrifying in that they include confidential information. Device and location lock is an essential element to prevent the risk.<\/p>\n\n\n\n

Establishing operational rules is the key if there is an unavoidable need to take out or bring in work or to introduce a teleworking system. This may include obtaining permission from the responsible person, limiting devices and locations, and so on.<\/p>\n\n\n\n

Implement a system to prevent misdirected emails<\/h4>\n\n\n\n

System implementation will help you prevent misdirected emails and incomplete attachments. In most cases, such system includes automatic sending after approval by the superior, automatic CC of the recipient, reconfirmation before sending, and so on, and these functions are effective for protecting confidentiality.<\/p>\n\n\n\n

Protect information from a malicious third party<\/h4>\n\n\n\n

A malicious third party is a threat for information leakage. Are there any restrictions to access data? If anyone can access the environment, download data, or even just read some documents, all of the elements can cause the information leakage.<\/p>\n\n\n\n

Keep documents out of view and set screensaver for computers when you leave your desk. As for disposing of digital devices and credit cards, physical destruction is the ultimate way to prevent the leakage. Establish such company wide rules after careful consideration.<\/p>\n\n\n\n

Prohibit individual dissemination of information<\/h4>\n\n\n\n

Even if information is handled and disposed properly at a site, there are cases in which an employees\u2019 daily action can lead to information leaks. For instance, their posts on social networking services (SNS), blogs, or in conversations with employees of other companies could be causes. Imagine how important conducting employee training is to ensure confidentiality.<\/p>\n\n\n\nBack to Contents<\/a>\n\n\n\n

For Outsiders<\/h3>\n\n\n\n

Manage confidential information<\/h4>\n\n\n\n

ID and password management is indispensable for avoiding increasingly sophisticated external attacks. Thoroughly implement measures such as using hard-to-guess combinations like names, avoiding multiple use with other devices, managing them in locations that are invisible from others, and so on.<\/p>\n\n\n\n

Software Security<\/h4>\n\n\n\n

Security software is effective in preventing the leakage of personal information due to cyber-attacks, as it can deal with new methods that standard OS functions have difficulties with controlling, thereby it will result in reducing the risk of security incidents. Make sure to update the files to keep up with the ever-evolving methods and computer viruses.<\/p>\n\n\n\n

Regular updates and check for vulnerabilities<\/h4>\n\n\n\n

In many cases, attacks from outside parties target vulnerabilities in systems and applications. Therefore, regular system updates and vulnerability checks are necessary to prevent information leaks by outsiders.<\/p>\n\n\n\n

In the unlikely event that a vulnerability is discovered, check the degree of danger and impact, and take appropriate action by installing new security tools, suspending use or enhancing the system features.<\/p>\n\n\n\nBack to Contents<\/a>\n\n\n\n

Main Causes<\/h2>\n\n\n\n
\"blog\"<\/figure>\n\n\n\n

The main causes of information leaks can be categorized as human error or intentional misconduct by internal staff and malicious attacks from outside. We provide specific examples of each.<\/p>\n\n\n\n

Internal Human Error<\/h3>\n\n\n\n

Information leaks due to internal human error are mainly caused by misplaced or lost recording media such as laptops, documents, and USB memory sticks, as well as mishandling of emails such as wrong destinations or attached files.<\/p>\n\n\n\n

Inadvertent conversations in public places also can be the cause. For instance, office building, elevator, cafe, pubs, etc., confidential information will be revealed to a third party in such locations if you are not aware of the threat. Avoid talking about your organization including the management and new products or services.<\/p>\n\n\n\n

Other potential sources include inadvertent transmission on social networking services, such as posting confidential information prior to release or personal information about customers. Even if anonymous, be aware of the risk of identifying the sender and the organization to which you belong from the content of the message.<\/p>\n\n\n\n

Internal Intentional Factor<\/h3>\n\n\n\n

Internal intentional leaks of information may include unauthorized transmission of data and manipulation by retirees. This may be due to economic reasons or distrust or dissatisfaction with the organization.<\/p>\n\n\n\n

External Malicious Attack<\/h3>\n\n\n\n

Typical causes of information leaks due to external attacks are unauthorized access and malware infection. Malware refers to malicious programs or software that cause terminal malfunctions or information leaks. Targets are personal and customer information, misuse of IP addresses, and other occurrences. Beside that, pay attention to office eavesdropping and theft to protect confidential information.<\/p>\n\n\n\nBack to Contents<\/a>\n\n\n\n

When Information Leakage Occurs<\/h2>\n\n\n\n
\"blog\"<\/figure>\n\n\n\n

In the event of an information leakage, immediate action is required to minimize the damage. This section provides a step-by-step explanation of how to respond in the event.<\/p>\n\n\n\n

Step 1: Confirmation and Prompt Report<\/h3>\n\n\n\n

First, when you identify any signs or effects of an information leakage, immediately report it to the person responsible. Establish a structure in your organization to respond led by the person in charge, as well as policies and details of the primary response. Do not delete emails or files or perform any other unintentional operations so as not to erase evidence that may provide clues to the cause of the leakage.<\/p>\n\n\n\n

Step 2: Prevent Secondary Damage<\/h3>\n\n\n\n

Next, first measures should be taken to prevent the information leakage from spreading and causing secondary damage. It will be considered to shut down the network system or suspending services. In the event of a personal information leakage, the affected party may be contacted and asked to change their password or stop using the service.<\/p>\n\n\n\n

Step 3: Conduct a Reasonable Investigation<\/h3>\n\n\n\n

The next step is to investigate the cause. From a perspective 5W1H method, investigate the facts regarding the matter and try to secure evidence. When countermeasures have been clarified, companies are also required to promptly disclose the information to reduce the number of similar cases of damage.<\/p>\n\n\n\n

Step 4: Announcement to the Relevant Authorities<\/h3>\n\n\n\n

When information leakage occurred, consider whether or not to report the incident to business partners, consumers, or the relevant ministries and agencies, or to make a public announcement. If transaction or personal information has been leaked, unless there is a specific reason to the contrary, notify business partners and the individual concerned, apologize, and alert them to secondary damage.<\/p>\n\n\n\n

If the number of people are involved or the damages is remarkably diverse, announcements may be made on the website or at a press conference. In addition, if you face a request for money or suspection of unauthorized access, a prompt report to the police is indispensable.<\/p>\n\n\n\n

Step 5: Take Prevent Measures<\/h3>\n\n\n\n

The final step is to take prevent measures based on the investigation report. There may be some cases to discuss the disposition of employees or compensation for damages to the suspect.<\/p>\n\n\n\n
