Think of a situation where a small and newly established business has sacrificed of its data. Yes, the same appears to be a concern and also it does depict how strong its approach and security measures were. Data leakage is a serious concern for small and large businesses in today’s world. It is a situation when any kind of sensitive information is inadvertently exposed to such parties who can take advantage of the same causing financial losses, forensic investigations, reputational damage, future security cost and authoritarian penalties.
Knowing about Data Leakage
Data leakage is the unauthorized transmission of sensitive data of a business to an external destination through various cyber attack strategies. It can be through malware, viruses, ransomware or phishing. The means may be through emails, USB drives, cloud storage, or even by employees accidentally sharing sensitive information. Data leakage can be of intellectual property, financial records to customer information or any internal communications.
Prevention of data leakage
When you run a small business, there is need to understand every data leakage risk, anticipate it and guard against risk. Understanding risk is all about having a clear-eyed view of the other side of data leakage covering its consequences. A business need to be ready with preventing data leakage measures which includes a multi-faceted approach, integrated robust security steps, employee training, and vigilant monitoring. These are some top strategies which any business should implement to save it from major losses caused due to data leakage risk:
- Limit Access: Following “principle of least privilege” should be followed. Access to data should only be given as per the specific roles.
- Secure Cloud Storage: Audit of cloud environments should be regularly undertaken. It requires strict authentication of all databases and storage folders.
- Enforce MFA: All the data of the business should undergo Multi-Factor Authentication (MFA).
- Employees Training: Training should be given on regular intervals on data security and handling policies as well as on phishing and password management.
- Regular Security Audits: Periodic security assessments and audits should be done to know vulnerabilities and ensure observance with security policies. The small business can also consult various IT companies which offer comprehensive security and infrastructure assessments. This will ensure that data leakage risks are identified and mitigate effectively.
- Use Data Loss Prevention (DLP) Solutions: DLP tools should be used. They help the business to monitor, detect, and block unauthorized data transfers. The insider threats can be known and mitigation can be possible.
- Robust Incident Response Plan can help: A well defined incident response which includes specific roles and responsibilities, communication protocol and rapid response will help.
- Data Encryption: The best way to save data is doing encryption of sensitive data. This makes data unreadable to unauthorized parties.
Data Leakage Prevention Tools
For prevention of data leakage, it is better to use data loss prevention (DLP) tools. They help in continuously monitor and analyzing any potential violations of security policies. Also in addition to it, they work to stop them.
Here are some DLP tools which have two fold aspects. One covers laptops or email services, and other focus on data backup, archiving, and restoration. Characteristics of business DLP:
- Automation
Data is created and edited continuously and DLP tools automatically identify and classify the sensitive data. Automation has tools to distinguish and respond to threats rapidly.
- Analytics
DLP tools helps in analyzing data in any form, its location and application. This reduces the risk of data leakage.
- Context
When DLP tools are used, they find the issues from various sources. Any activity which appears to be normal in context can be suspicious in another. Any suspicious value, its pattern is identified and statistical analysis of data activity is performed.
- Response
In this tool, any potential policy violation is discovered. Based on it, response is initiated by the DLP tool.
To work looking into the Impact of Data Leakage
Data leakage has many consequences and can be devastating for businesses. Looking into such consequences, a business should work prior.
Financial Losses, reputational damage and regulatory penalties hit badly. So a business should have a robust arrangement for data leakage.
Not to forget the causes of the data leakage.
Some reasons are weak password and credential theft. So business should use strong and new password every time. Weak password can be cracked easily. Eye on phishing and social engineering scams should be there. It includes deceptive emails, text messages that applies trick to reveal sensitive information. Malware and Ransomware attacks bring a business to a complete standstill. Here the data is locked and heavy sum is asked to unlock it. Hence proper system should be maintained to lock critical and financial data.
At nutshell, small business should from the beginning onwards use a comprehensive approach to data security, have a vigilant management and robust security measures to prevent data leakage.
