How to Prevent Internal Data Breach In Your Business

The security of a system in a company really depends on procedures in the management of privacy management and data security. Breach data is a threat that is currently a challenge in many businesses. Most businesses tend to pay attention to data breach attacks from the external side of the company, and forget about attacks from the company's internal side. This article will discuss methods for preventing data breaches in the company's internal systems.

A data breach could have a negative impact on a company's customer loyalty, reputation, and competitive advantage. It is the responsibility of company executives and IT departments to ensure that company data remains within the firm, regardless of where it resides. Executives must understand how internal data breaches occur and help IT administrators in their attempts to secure networks in order to do this. 

How Data Breach Happens?

On a modern PC, data can be accessed via USB and Firewire connectors, CD and DVD recorders, and even built-in storage media slots. Business personnel can now use personal storage devices, such as USB memory sticks, iPods, digital cameras, and smartphones, to remove or copy critical information for malevolent intent or personal benefit.

The USB connector can retrieve data from a variety of sources, including detachable hard drives and media players, at rapid speeds. As a result, the USB port is one of the most vulnerable areas for stealing sensitive and secret data such as customer records, bank account numbers, patient medical records, and internal account information.

The Use Case of Internal Data Breach

When it comes to data security, the human aspect is typically the most difficult to control and forecast. While some companies invest in employee training in the hopes that a well-informed workforce, aware of the financial and reputational consequences of data breaches, will increase vigilance and deter poor security practices, others believe that a well-informed workforce, aware of the financial and reputational consequences of data breaches, will be sufficient to increase vigilance and deter poor security practices. However, in many cases, a single irresponsible employee is all that stands between a business and a damaging security event. Malicious insiders, dissatisfied employees who wish to harm a company's brand or steal data on their way out, are always a threat.

Social Engineering Attack

Although social engineering is theoretically an external danger, it only works if someone inside a firm can be persuaded to provide information. It indicates that employees are duped into handing up passwords or other sensitive data. Attackers mimicking friends or other trustworthy sources and asking for personal information or surprising offers and awards from well-known brands that contain or link to malware are examples of social engineering.

While anti malware and antivirus technologies can assist detect phishing emails, the best way to combat social engineering is through training. Employees must be trained in the many methods in which they may be approached by external attackers and how to respond when they receive questionable requests. In order to avoid social engineering, you must first grasp what it is.

Unsecured Data Sharing 

Employees disclosing sensitive material with third parties outside the organization, whether publicly or privately, can be disastrous. This frequently occurs as a result of inattention: a reply all button is pressed instead of a simple reply, information is sent to the incorrect email address, or something is mistakenly made public.

Training rarely helps in these situations because they include human errors, which we are all prone to. Specialized software, such as Data Loss Prevention (DLP) solutions, can assist firms in keeping track of sensitive data and ensuring that its transmission, whether by email or other internet services, is limited or completely prevented.

Unauthorized Internal Device

Many data protection rules are focused on data transfers outside the company network via the internet, but they overlook another common method: portable devices. USB drives, in particular, have long been the devil of data security plans. USBs are easy to lose or steal, but they're also convenient to use, as seen by the now-famous Heathrow Airport security incident, in which a negligent employee misplaced a USB containing over 1,000 private files, including highly sensitive security and personal information.

The simplest way to prevent these kinds of breaches is to disable all USB and peripheral connectors. The utility of USBs in the workplace, on the other hand, cannot be denied. There are security steps that businesses can take if they still want to use USBs. The encryption of all files transferred to USB sticks, as well as a trusted devices policy that allows only trusted devices to connect to a work computer, are two of the most important.

How To Prevent Internal Data Breach?

While dealing with the difficulty that USB storage devices are heavily relied on by businesses to effortlessly travel and transmit data, organizations must adopt a proactive approach and prevent any breaches.

Developing a strict "no-use" policy could make it difficult for many employees, especially remote workers, to do their jobs. Instead of restricting the use of all portable devices, the answer is a compromise that develops stringent restrictions for USB port use on a user-by-user basis.

IT managers can be more granular when defining policies thanks to third-party technologies. For example, policies can be defined to enable "read-only" access to a specified set of users on available devices, while allowing (or prohibiting) access to others. These policies can also be used by both local and remote users. Businesses should search for software that can lock down all possible data leakage points and implement rights and policies to govern who has access to which files, where, and when.

Furthermore, IT administrators must be able to report and track data breaches. Administrators may observe all attempts at restricted activities, including the individual engaged, the type of activity, and when and where the breach was attempted, thanks to the central gathering of an audit trail.

To achieve a healthy balance between organizations and employees, a solid and flexible security strategy must be implemented. Finally, a high-quality third-party security software solution may give rules and permissions that are clear to both employees and those applying them, ensuring that data does not leave the workplace.
