Best Data Security Strategies To Implement in 2023
A thoughtful, structured strategy is vital to protecting sensitive data. Organizations and individuals should consider the following policies, procedures, and practices when designing a data security program:
Risk Assessment
An extensive risk assessment is the first step in understanding an organization’s vulnerabilities. Risk assessments allow decision-makers to detect potential threats and weaknesses and allocate resources toward addressing the identified gaps.
Assess vulnerabilities. Assessments must evaluate the entire infrastructure, including networks, systems, applications, and storage devices or services.
Understand threats and attack vectors. Understanding current cyberthreats and vulnerabilities can help organizations realize possible attack vectors and prevent unauthorized access. Another option is using threat modeling to anticipate malware, phishing, or an internal data breach.
Categorize risks and prioritize the most pressing ones. After completing the assessment, organizations must prioritize the risks based on their impact and likelihood. Address the most probable and significant threats first. Implementing mitigation strategies, process improvements, and more advanced technologies can strengthen an organization’s cyberdefenses.
Asset Inventory
A complete asset inventory is essential to securing data. It involves classifying assets and determining the structure and flow of information. The process reinforces data protection efforts by focusing on valuable assets.
Classify based on sensitivity. Start by identifying critical information that requires the most protection. Sensitivity levels typically include:
- Low Sensitivity Data: General information deemed safe for public consumption, such as website content. This data cannot be compromised.
- Medium Sensitivity Data: Private information shared within the organization. There could be mild consequences if someone leaked this data.
- High Sensitivity Data: Critical information shared with a limited number of executives or specialists. A data breach would be catastrophic.
Map assets. Data mapping visualizes an organization’s structure and flow of information, including its interaction with different systems and users. It offers insights into where sensitive data resides and how it is stored, transmitted, and accessed. This intelligence enables organizations to make more informed decisions about data protection and establish priorities.
Data Security Policy
Organizations must design comprehensive data security policies that outline clear rules and procedures for handling sensitive data. These policies set employee, stakeholder, and internal user expectations regarding data protection. It should cover workstation security, acceptable usage, remote access, and BYOD (Bring Your Own Device) rules. A well-communicated policy raises data security standards across the organization.
Set clear rules and controls. Develop policies that outline specific rules, controls, and procedures for handling, storing, and sharing important data. Ensure all practices are consistent throughout the organization.
Utilize a risk-based approach. This approach considers the inherent dangers of using, storing, and transmitting data in a particular manner and reduces those risks. Address high-risk areas before other concerns.
Undergo regular audits and update policies. Conduct regular audits and improve policies to remain prepared for an evolving threat landscape and compliant with regulations.
Mobile Data Security
Considering their increased usage, data security for mobile devices is critical for organizations. Storing and accessing data on mobile devices demands stricter controls, given the potential for loss or theft. Measures like multi-factor authentication (MFA), encryption, and secure communication channels are crucial to keeping data safe.
Implement access controls. Multi-factor authentication requires each user to provide multiple forms of identification before accessing data or systems. Once verified, users can interact with the information. Avoid public WiFi or untrusted networks to minimize the risk of data breaches or interception.
Centralize security. Managing the security settings of mobile devices from a central platform enables organizations to enforce uniform policies and quickly respond to incidents and threats.
Protect mobile data with encryption and remote wiping. Encrypting data stored on mobile devices offers an additional layer of security if it is lost or stolen. In the event of a lost or stolen device, remote wiping allows organizations to erase sensitive data without physical access, preventing potential breaches.
Database Security
Securing databases often involves a multi-faceted approach to protect confidential information from unauthorized access, downloading, or sharing. Organizations should set administrative controls, update database software, encrypt files, apply multi-factor authentication, segment and duplicate data, and conduct routine audits to prevent devastating breaches or regulatory non-compliance.
Establish administrative controls. Set up stringent administrative controls for databases, limiting access to authorized, relevant personnel. Restrict administrative controls to those that require them to perform their job. Implementing Just-in-Time Privileged Access Management (JIT PAM) grants users temporary access to specific data, minimizing the potential attack surface.
Encrypt stored data. Robust encryption safeguards sensitive information even if attackers penetrate the database’s other defenses. Without the appropriate decryption key, intruders would need to decode the data before accessing it.
Conduct audits. Set up an auditing system and monitor the database. Review audit logs to detect unauthorized access and unusual behavior. Enabling real-time alerts for suspicious activities can lead to quicker incident response.
Cloud Security
Cloud security demands special attention due to the unique characteristics of the environment. Organizations should have access controls, encryption standards, and employee training programs to secure data stored in private or public cloud environments.
Institute access controls. Strict controls and authentication mechanisms help organizations manage user access to cloud storage and resources. Permit appropriate access based on their role. Review and update privileges to reduce the risk of unauthorized access.
Use encryption to protect privacy. Cloud services can usually encrypt data at rest and in transit to prevent interception and unauthorized access. The best protection strategies secure data in each of its three states. Determine if the cloud storage provider uses industry-standard algorithms and practices. Examine the service’s privacy policies and compliance certifications as well.
Maintain backups and disaster recovery plans. The cloud is not immune from human error or natural disasters leading to data loss. Organizations should back up irreplaceable data to a separate cloud server or keep additional copies at a secure, offsite location. These redundancies might seem unneeded, but they protect against sudden data loss from cyberattacks, natural disasters, or hardware failure. Organizations might still require professional data recovery services in some situations.
User Behavior
Monitoring user behavior helps identify insider threats and compliance issues. Security Incident and Event Management (SIEM) tools track user behavior and provide insights to aid decision-making. Custom-built analytics and scalable solutions enhance visibility and improve responsiveness to potential threats.
Discover insider threats. Analyzing user activity for abnormal or suspicious behavior, including data exfiltration or misuse of privileges, can reveal insider threats within the organization beforehand.
React to real-time anomalies. Systems that can detect real-time anomalies provide organizations with a more complete overview of user behavior and network traffic. These systems use machine-learning algorithms to establish a normal baseline and flag irregular activity.
Prepare incident response plans. Reviewing user logs after an attack can determine the scope and probable impact of the incident. This practice provides more information about the specific method, recognizes compromised data, and helps formulate an incident response plan, including containment and mitigation strategies.
Data Privacy
Respecting data privacy is not only a moral obligation. It is also a legal requirement. Organizations should have privacy policies that align with their operational structure to comply with regulations and reduce the risk of a data breach.
Develop comprehensive data privacy policies. Establish unambiguous privacy policies that govern how personal or private data is collected, processed, stored, and shared.
Secure storage devices and encourage responsible data handling. Data is as safe as its weakest link. Organizations should have robust security measures to protect user privacy against cyberattacks and unauthorized access. Ensure the physical safety of storage devices, encrypt sensitive data, and update protocols as necessary.
Comply with data protection regulations. Remain compliant with all relevant data protection regulations, such as GDPR or CCPA.
Least-Privilege Access
The principle of least privilege (PoLP) states that administrators grant users the minimum access required to perform tasks. Least-privilege access ensures that critical assets are shared with fewer people, which minimizes the organization’s exposure to data mishandling or misuse. Enforcing the principle of least privilege requires clear governance and multi-factor authentication.
Define access controls. Granular access control mechanisms assign permissions based on user roles and responsibilities. Avoid blanket permissions that grant excessive access to data or systems. If needed, adopt a Just-in-Time Privileged Access Management (JIT PAM) approach and revoke permissions once employees complete the task.
Assess user access and privileges. Regular assessments of user access can locate outdated and unnecessary permissions for members who have transitioned to new roles or left the organization.
Audit privileges. Scheduling audits of the organization’s permissions can uncover attempts to exceed privileges or engage in unauthorized activities. It also records who accessed what data and when, which can be critical in internal investigations and ensure compliance.
Employee Training
Educating employees on handling corporate assets and spotting malware, phishing, and other forms of social engineering is essential. Frequent training provides up-to-date information on the threat landscape and advances a people-centric approach to data security. Having more knowledgeable employees mitigates the probability of data breaches and multiplies the effectiveness of most measures.
Hold regular training sessions. These training sessions will increase employee awareness by explaining the latest security threats and reinforcing the best preventative practices. Cover topics such as phishing and other social engineering techniques, password hygiene, and immediately reporting potential incidents.
Customize training for specific roles. Recognize that different jobs have unique data security considerations and tailor the training sessions to address those challenges. For example, the accounting department might need additional resources on financial fraud prevention. In contrast, IT might need specialized training on securing networks.
Foster a culture of security awareness. Promoting a security-aware culture among employees strengthens every aspect of a data protection strategy. Urge employees to report potential threats or incidents promptly. A straightforward reporting process helps escalate matters to the appropriate personnel for investigation and resolution.
