Each day, companies in the digital era handle a great deal of confidential data. In every organization, data includes everything from customer records to business plans. Even so, because they depend more on digital data, companies are more vulnerable to cyberattacks. If a company has weak security rules, it may suffer from data breaches, money loss, lawsuits, and a bad reputation.
A highlight of the 2023 DBIR published by Verizon is that over three-quarters of all incidents involved people committing errors, abusing privileges or using social engineering. The rising number of incidents highlights why companies should build and maintain effective internal security rules.
One of the most common yet overlooked areas of vulnerability is how employees send files via email. While email remains a primary communication tool, improper file-sharing practices can expose sensitive information to cybercriminals. Businesses must adopt comprehensive data protection strategies to reduce these risks and strengthen their internal security policies.
This article explores the significance of internal security policies, key areas of vulnerability, and detailed strategies to bolster data protection efforts.
Why Strong Internal Security Policies Are Critical
1. Growing Cybersecurity Threats
Cyberattacks have grown increasingly sophisticated, targeting businesses of all sizes. The 2023 IBM Cost of a Data Breach Report found that the average cost of a data breach reached $4.45 million globally, a 15% increase over three years. Small businesses were not spared, as cybercriminals often see them as easier targets due to weaker defenses.
Key threats businesses face include:
- In phishing attacks, people are fooled by emails that persuade them to share their company information or open malicious files.
- With BEC, hackers pretend to be leaders in the company, asking for money or confidential data.
- An attacker uses ransomware to take over your system until you pay to unlock it.
- Data can be exposed by anyone in the company, either on purpose by a malicious attacker or by accident by someone not aware of their actions.
2. Regulatory Compliance Requirements
Businesses are subject to strict data protection laws depending on their location and industry. Non-compliance can lead to hefty fines and legal repercussions.
Key regulations include:
- General Data Protection Regulation (GDPR) in Europe.
- Health Insurance Portability and Accountability Act (HIPAA) in the U.S. (healthcare sector).
- California Consumer Privacy Act (CCPA) in the U.S.
Fines for GDPR violations, for instance, can reach up to €20 million or 4% of annual global turnover, whichever is higher.
Common Security Gaps in Internal Policies
1. Sending Files via Email Without Encryption
Email is often the default method for sharing files. However, unsecured email attachments can easily be intercepted during transmission. The Verizon 2023 report highlighted that email was the most common initial attack vector, accounting for over 36% of breaches involving human error.
2. Excessive Employee Access to Sensitive Data
Many businesses fail to restrict data access based on employee roles. This exposes critical information to those who do not need it, increasing the risk of accidental or intentional leaks.
3. Weak Passwords and Authentication Practices
A 2023 survey by NordPass found that 123456 and password remain among the most commonly used passwords, despite repeated warnings. Such weak credentials provide easy entry points for cybercriminals.
4. Lack of Employee Training
According to a 2022 Stanford University study, 88% of data breaches are caused by employee mistakes. Employees often unknowingly click on malicious links, download infected files, or fail to identify phishing attempts.
How to Improve Internal Security Policies for Data Protection
1. Implement Secure File Transfer Solutions
Relying solely on email attachments for file sharing is no longer safe. Businesses must adopt secure file-sharing platforms that offer encryption and advanced access controls.
Best Practices for Sending Files Securely:
- Select security tools that protect your data during transit and at all times when it is stored.
- Replace attachment use with the option to share secret files through time-limited links.
- Use services such as TitanFile: TitanFile keeps files secure, logs who accessed them, and meets requirements like HIPAA and GDPR.
- You can enable encryption for your emails using Microsoft 365 and Google Workspace. Make sure staff members are shown how to use each feature.
2. Enforce Role-Based Access Controls (RBAC)
Restrict access to sensitive information based on employees’ roles and responsibilities.
Steps to Implement RBAC:
- Identify critical data: Determine which information requires restricted access.
- Define roles: Categorize employees based on their data access needs.
- Assign permissions: Provide the minimum level of access necessary to perform their duties.
- Conduct regular audits: Review user access logs to identify unauthorized attempts or potential misuse.
3. Strengthen Password and Authentication Protocols
Strong passwords and multi-factor authentication (MFA) can significantly reduce unauthorized access.
Password Security Checklist:
- Won’t allow easy passwords: require every password to include uppercase, lowercase, numbers, and special characters.
- Use multi-factor authentication (MFA): Certify all users’ identities with another layer (e.g., a code received on their phones).
- Ask your employees to save their login details in a password manager.
- Set password renewal every 90 days as part of the security rules.
4. Educate Employees on Cybersecurity Best Practices
Employee awareness is a critical defense against cyber threats.
Training Topics to Cover:
- Phishing identification: Teach employees to recognize suspicious emails and avoid clicking on unknown links.
- Secure file transfer practices: Demonstrate how to securely send files via email using encryption or secure platforms.
- Incident response: Ensure employees know how to report potential security breaches promptly.
5. Monitor and Audit Data Usage
Continuous monitoring helps detect unauthorized data access and potential breaches.
Key Actions:
- Deploy Data Loss Prevention (DLP) software: Prevent sensitive data from being shared outside the organization.
- Track file transfers: Keep logs of files sent via email and shared through cloud platforms.
- Set up automated alerts: Receive notifications for unusual activity, such as large data transfers or repeated login failures.
6. Encrypt Data at Rest and in Transit
Encryption protects data from unauthorized access, even if intercepted.
Encryption Strategies:
- Use end-to-end encryption for emails and file-sharing.
- Encrypt storage devices: Ensure servers, databases, and employee laptops are encrypted.
- Implement VPNs: Secure remote work connections by using Virtual Private Networks.
7. Develop an Incident Response Plan
Preparation minimizes damage when security breaches occur.
Key Components of an Incident Response Plan:
- Detection: Early identification of security incidents.
- Containment: Isolating affected systems to prevent the spread.
- Eradication: Removing malware or unauthorized access.
- Recovery: Restoring systems and verifying their security.
- Post-incident review: Evaluating what went wrong and updating security policies.
Benefits of Robust Internal Security Policies
Implementing comprehensive security measures offers multiple advantages:
- Protects data such as business and customer details from threats of data breaches.
- Following all laws keeps you from facing fines or court cases.
- Increases trust between the company and its customers by assuring security.
- More efficient operations: Cybersecurity steps that are easy to execute minimize downtime.
Final Thoughts
Businesses need to focus on data protection, because it is no longer optional. Securing company data and abiding by important regulations should be a main objective for every company. If you use encryption and services such as TitanFile to send files via email, it’ll help keep your data safe and boost cybersecurity awareness among employees.
Businesses can help protect their data by applying file transfer security, using RBAC, setting good password policies, giving employees training, using encryption and having an incident response plan.
Here’s a summary of what the survey revealed:
74% of breaches last year were caused by errors made by the people involved.
The average cost of a data breach in 2023 was $4.45 million, according to the IBM Report.
According to Stanford, most data breaches happen because of employee mistakes.
