What Is Encryption-As-A-Service In Cybersecurity?

At BestCybersecurityNews, we help entrepreneurs, solopreneurs, young learners, and seniors learn more about cybersecurity.

Encryption is a widely-used security solution to protect data privacy and meet regulatory requirements. It encrypts information into ciphertext, which requires a decryption key in order to decipher.
Data encryption is an efficient method to safeguard your business data and guarantee its safety at all times. It also helps safeguard remote work areas and prevents data theft.

Is EaaS the Solution to Protecting Your Data?

Encryption-as-a-service (EaaS) is a type of cybersecurity solution that helps businesses protect their sensitive data and information by encrypting it. EaaS solutions are typically offered by cloud service providers and can protect files, email communications, and other sensitive materials. They can encrypt files on servers and employee workstations, as well as in the cloud.
This is an essential cybersecurity technique that shields data from unauthorized access or alteration. Without encryption, hackers can cloak malicious packets as local traffic and gain unauthorized entry to organization data databases, where they could then steal or modify the information in order to commit fraudulence.
Asymmetric encryption encrypts messages using two keys, one private and the other public, that are mathematically linked. This ensures that the encrypted message cannot be decrypted by an unauthorized person. Asymmetric encryption requires less processing power to encrypt and decrypt, thus reducing delays.
However, this approach could prove disastrous if someone obtains access to the private key of an organization’s encryption solution. As asymmetric encryption relies on matching keys for its success; if these are compromised, all communication may be disrupted.
Symmetric encryption, on the other hand, uses a single key for both encryption and decryption. This type of encryption is often employed by cloud providers due to its higher level of security compared to asymmetric algorithms.
This algorithm is an effective choice for protecting websites, as it creates a strong cryptographic key that can only be decrypted by a specific individual or authority. This effectively guards against hacking, phishing attacks, and other forms of malware that attempt to intrude on web browsers in order to steal data.
Asymmetric encryption can also protect emails and other forms of communication by ensuring that only authorized personnel can read the text. This is beneficial when companies send confidential or sensitive documents to clients or colleagues for review.
Asymmetric encryption methods are frequently employed for cloud-based services like email and instant messaging since they enable companies to encrypt their data at the network layer before transmission. This type of encryption, known as level 3 in the OSI model, is a highly effective way of safeguarding users‘ privacy.
Many companies and organizations require encryption of their data in order to abide by regulations and industry standards, as well as to show auditors that their information is secure. Doing this helps avoid penalties or other repercussions if a company fails to adhere to these laws and guidelines.
Healthcare organizations must abide by security standards and protocols regarding patient data handling. This means their cloud-based solutions should use a strong encryption standard like Advanced Encryption Standard with a 256-bit key to protect medical records and other sensitive personal information.
When selecting an EaaS provider, review their cybersecurity policies and procedures. These should include data ownership/access policies, monitoring of security events, as well as the revocation of user access at any time. Furthermore, ensure they offer granular controls over which data can be encrypted and which not.

Is BYOE the Key to Secure Encryption-as-a-Service?

BYOE (Bring Your Own Encryption) is a security model that enables cloud service customers to utilize their own encryption software and manage their own keys. To do this, customers deploy virtualized instances of the encryption software alongside applications hosted in the cloud to securely encrypt data before it is stored.
SecurityWeek recently reported on a strong trend in cloud security: many major organizations are already using it and many cloud providers plan on offering this option to their customers. Nevertheless, BYOE comes with its own set of risks and difficulties.
One of the key concerns with BYOE is that companies may fail to properly configure their encryption package, leaving them with an ineffective protection of sensitive data – or worse yet, no encryption at all. This presents a serious risk for companies.
Another critical concern with BYOE is that it creates an environment in which hackers could potentially gain access to encryption keys used for data encryption in the cloud. This puts data at risk, particularly when those keys are held by a third party, such as a CSP.
A secure BYOE solution requires data owners to have full control over encryption and key management policies, including privileged user access controls. These guidelines should specify who can view specific data through what process and at specified times.
Encryption solutions must provide visibility into the status of encrypted data to enable users to detect any threats. For instance, they should be able to integrate security logs with popular Security Information and Event Management (SIEM) tools.
Furthermore, encryption solutions must be effortless to set up and deploy, eliminating the potential risk of human error that could prove costly in the long run.
Finally, encryption solutions must be scalable and offer high performance for all types of unstructured data, such as files, folders, databases, and big data environments. This is necessary in order to meet compliance requirements under various regulations.
These solutions should also enable data migration between cloud and on-premises environments. This can be especially advantageous for large companies with massive data sets to relocate, as well as small businesses that aren’t yet prepared to store all their information offsite.
Finally, BYOE can be an invaluable tool for organizations to protect sensitive data and avoid issues like Heartbleed-like vulnerabilities. However, it should be used with caution, according to cybersecurity expert Mark O’Brien.
