Data Security Risk And Common Threat

Data security is a critical concern in today’s digital landscape, where immense amounts of sensitive information are stored and transmitted online. As organizations increasingly rely on technology for their operations, they become prime targets for a variety of threats that can compromise data integrity, confidentiality, and availability, and understanding these risks is essential for developing effective security strategies.

Data Security Risks and Common Threats

Accidental Data Exposure 

Accidental data security threats occur when sensitive information is unintentionally exposed due to employee actions. Unlike deliberate hacking attempts, these breaches happen when someone mistakenly shares or grants access to data to the wrong person, misplaces important files, or improperly handles information due to a lack of awareness about company security policies. To mitigate this risk, businesses should ensure all staff undergo basic and advanced training about data security policies and best practices to ensure they understand the need to handle sensitive information safely. 

Phishing Attack 

In a phishing attack, cybercriminals send an email, SMS, or instant messaging that seems to originate from reputable sources, such as banks, trusted partners, or familiar personalities. As a result, the recipient sees the email or SMS as legitimate and follows the instructions, which most likely demand clicking on a link or revealing certain personal details. Once this action is done, the attacker can access the organization’s sensitive data or cause the recipient to download malware.

Insider threat 

Insider threat is similar to accidental data exposure; it arises from individuals within an organization who have authorized access to its systems and data. This occurs when an employee intentionally or inadvertently divulges sensitive customer data or company details to unauthorized users and the public without the company’s permission.

Insider threats can happen in three ways, including: 

• Compromised Insider: A hacker accesses an unsuspecting employee’s account details, such as usernames and passwords, and performs malicious acts using such details while posing as the user. 

• Malicious Insider: The employee is fully aware of the need to protect the company’s data and the effect of negligence but goes ahead and exposes the company’s sensitive information to an outsider for selfish interests.

• Non-malicious Insider: The insider is not fully acquainted with the company’s security policies or is aware but negligently created a loophole for attackers to penetrate and access sensitive information.

Malware

Malware is computer software designed by cybercriminals to steal information or damage system software. They can access a computer system and spread their damage throughout an entire network via email, wireless connections, downloading phony apps, or web-based phishing attacks. Common malware types include worms, viruses, Trojan viruses, and spyware. 

Ransomware

In ransomware, attackers steal valuable and sensitive data or cause technical harm to the system, denying access. The cyber attackers hold onto the sensitive data they have stolen or keep the system damaged in exchange for certain demands, which can range from money to access to other valuable details from the company. Ransomware today is one of the most common forms of cyberattack, and backing up sensitive data or creating a robust response system can effectively mitigate the risk. 

Cloud Data Storage 

Companies deploy cloud storage as an efficient system to easily store and access data while fostering seamless collaboration across borders. However, the process of transferring and accessing these files can be vulnerable to attacks, making it easier for anyone with the right skills and malicious intent to access the stored data. Such vulnerability demands streamlined access control protocols to forestall unauthorized access to critical data, either by chance or from an insider with selfish intentions. 

Strategies For Safeguarding Your Data 

With the pervasive spread of cyber attacks and security threats on stored or shared data, implementing effective strategies to protect data has become a core responsibility of every business, not just for maintaining privacy but also for ensuring compliance with legal standards and building trust with customers. Let’s discuss some of the top strategies for safeguarding your data. 

Ensuring Regulatory Compliances 

Ensuring regulatory compliance is a fundamental strategy for safeguarding data within organizations. This approach involves adhering to various laws and regulations that govern the collection, storage, processing, and management of personal and sensitive information, which vary across different regions but share the common goal of fail-proof security for data.

Some of these regulations include the following:

• GDPR: This law ensures that organizations protect the data of European citizens by strictly adhering to a set of protocols and regulations when using customer data. 

• Gramm-Leach-Bliley (GLB) Act: An act of the 106th United States Congress that regulates the management of nonpublic personal information about consumers by financial entities. 

• ISO 27001: The ISO 27001 is an international regulatory framework that helps organizations improve, implement, manage, and employ strategies to establish information security management systems. 

• HIPAA: A federal health law that protects patients’ health information from being disclosed to third parties without their consent. It involves a privacy and security policy where data is kept private until stated otherwise. 

• PCI DSS: The Payment Card Industry Data Security Standard (PCI DSS) is a critical framework designed to protect cardholder data during transactions. Developed by major credit card companies, including Visa, Mastercard, and American Express, PCI DSS establishes a set of security requirements that organizations must follow to ensure the secure processing, storage, and transmission of credit card information.
   
• CCPA: The CCPA is a statutory document formulated to streamline privacy rights and consumer protection for California residents. Among other rights, the CCPA empowers customers with the right to know which of their data is currently in use and how the data is being used. 

• PIPEDA: The Personal Information Protection and Electronic Documents Act is a Canadian data privacy law that controls how organizations obtain, deploy, and share the personal data of customers as they conduct their commercial activities. 

Best Practices For Data Security

Data security is not a single process that guarantees optimal information protection. Rather, it involves a series of strategic steps, policy implementations, periodic examinations, and IT infrastructure updates that establish a resilient firewall against data breaches and attacks. Below are some best practices to ensure a comprehensive data security framework guides all your data operations. 

Identify your sensitive data

Take an inventory of all your data assets and determine what qualifies as sensitive information. Afterward, identify and record the location of all data sets labeled “sensitive or confidential” across various storage locations, including cloud databases. Also, find out whether these segments of sensitive data are exposed to or at risk of unauthorized access in their storage locations and regularly update this data inventory. 

Proactively Prepare for Potential Threats

While setting security protocols and access control systems to avert data security threats, it is crucial to prepare for worst-case data breach scenarios. Consequently, set up an incident response system to not only curtail the scale of the data attack but to help build up from the damage without grounding the entire operations of your business. It is also critical to educate your staff on how to respond in severe and minor cases of data security threats, ensuring there are no loopholes on the side of human resources. 

Encrypt Your Data

Data encryption deters unauthorized access to stored or transiting data, ensuring data safety at any point in its lifespan. Beyond encryption, it is also imperative to review encryption tools and measures and update to the latest standards as cyber threats are continually evolving. 

Delete Unused Data

Unused data lying dormant in storage locations can still contain sensitive information that is vulnerable to exposure. Hence, it is of utmost essence to regularly examine stored data for unused variants and expunge them in their digital or physical formats. Also, empty all recycle bins and incinerate tangible data files to ensure there is no margin for exposure. 

Quickly Address Security Issues

Organizations should deal with security threats, minor loopholes, and cracks in their security architecture as soon as they happen, because cybercriminals are always on the prowl, scouting for the slightest gaps to exploit and launch attacks. Using automated remediation tools can greatly improve data security by allowing swift responses to potential threats while easing the workload on IT and security teams.
