8 best practices to protect data during rest and transit 

With the rise of online threats and data leaks, companies invest much money into sophisticated safeguards to safeguard their private data. Data at rest and in transit is vulnerable to various threats that can lead to financial damages. 

These strategies are crucial in today’s data-driven world, from advanced encryption techniques to secure network protocols. In a landscape where information is the key to success, understanding and applying these methods could be the difference between secure growth and a devastating data breach. 

In this blog post, we will delve into eight essential secret management methods designed specifically to safeguard your data, whether stationary or on the move.

Data in different states

Data can exist in multiple states and quickly transition based on an organization’s needs. Understanding these states is the first step in choosing effective encryption and secrets management strategies. These states include:

  • Data in Transit is when the data is moving between destinations, such as email, instant messaging, or collaboration platforms. Due to its exposure during transmission, it often presents a high-security risk.
  • Data at Rest refers to inactive data stored or archived on hard drives, databases, or other storage devices. Although less vulnerable than data in transit, it is still a target for attacks.

Best practices to protect data during rest and transit

Let’s explore specific secret management methods and best practices to protect data in its two states.


Encryption allows only people with appropriate permissions to access the information by converting your data into a secret code that can only be understood with the correct “key.” Implement strong encryption algorithms to encode data when it’s resting on your devices and during its journey through networks. The right decryption key will prevent someone from making sense of your data even if they manage to access it.

Access Control

Access control mechanisms work like security guards for your data. Data access is restricted based on user roles and permissions, which only authorized individuals can view or modify sensitive information. By setting up proper access controls, you can prevent unauthorized people from getting confidential data, reducing the risk of data breaches.

Secure Data Storage

It is imperative to store data in secure locations to safeguard against prying eyes. Think of it as keeping valuable items in a locked safe. Use encrypted databases or servers with passwords to keep your information safe from people who don’t know how to use it and from possible hacking. This way, even if someone tries to break into your storage, they won’t be able to make sense of the encrypted data without the decryption key.


Two-factor authentication bolsters the safety of your information. It requires you to provide two distinct forms of identification, such as a password coupled with a fingerprint scan or a single-use code. This dual security layer ensures that even if an unauthorized individual manage to obtain your password, they still require an additional unique piece of information to access your data.

Two-Factor Authentication

When two-factor authentication is active, you must prove who you are for an added layer of security. You need to give two things, like a password and a scan of your fingerprint or a special code that only works once. This double-locking mechanism ensures that even if someone gets hold of a password, they still need additional information to access the data.

Rotate secrets

Frequently rotating secrets is essential for maintaining security. When a secret remains unchanged for extended periods, the risk of compromise increases. This is especially concerning when multiple individuals have access to the same secret, as it raises the likelihood of accidental leaks or intentional hacking by malicious actors.

Automate passwords

Implementing automatic password generation is a vital move in improving security measures. Passwords created by machines are random and unique, thereby significantly reducing their vulnerability to hacking. On the other hand, passwords created by humans tend to be predictable and simpler for hackers to decipher.

Manage Privileges

Users and applications with high privileges hold the keys to sensitive and critical data, making them potential sources of data leaks, whether intentional or accidental. According to the principle of least privilege, users and applications should only be granted the privileges necessary to perform their specific tasks. Any unnecessary access should be avoided, minimizing the risk of data exposure.

Detect Unauthorized Access

Even with good security measures, no system is completely safe, and it becomes essential to detect unauthorized access swiftly. The sooner unauthorized access is identified, the quicker it can be addressed, minimizing potential damage and limiting the scope of the breach.

By implementing effective intrusion detection systems and continuous monitoring, suspicious activities can be flagged and investigated promptly. Being proactive in detecting and responding to unauthorized access is vital to safeguarding sensitive data and maintaining the integrity of your security measures.

The Bottom Line

Securing data and managing confidential information are crucial elements in a company’s data security blueprint. By implementing effective strategies and solutions, businesses can safeguard their data against potential breaches, which often result in financial losses due to penalties, legal expenses, and revenue decline. Organizations need to comprehend the methods of secret management, which play a pivotal role in protecting data at rest and in transit. By doing so, they can fortify their data security measures and guarantee the safety of their valuable information. This level of understanding boosts their security posture and contributes to their overall business resilience.
