Encryption is the transformation of plaintext data into ciphertext (encrypted text), which means the destruction of its structure in such a way that without the appropriate decryption key, it is impossible to read the information.
The two main types of Encryptions:
- Symmetric
- Asymmetric
Symmetric encryption means use of one key, intended for both encryption and decryption. It’s faster since only receiver side must have a key, but there is a need to maintain the security of key.
Asymmetric encryption is distinguished by the presence of two keys – a public key and private secret key for encryption and decryption, respectively. In this way, a user can share a public key with anyone without sending a secret one.
The strength of the encryption lies in complexity of algorithms and key length such that it becomes computationally impossible to decrypt the plaintext without use of a key if the entity is unauthorized. Hence, encryption plays a big role in securing data and communication as it provides confidentiality, integrity, and authentication. It protects sensitive information against unauthorized access while it is being stored or transmitted and secures online transactions from data breaches. With the ever-increasing cyber-attacks, encryption is the backbone of digital communications concerning privacy and trust.

What is security posture?
Security posture can be understood as the overall status of a company’s cybersecurity readiness. It can be improved by addressing the gaps after the assessment, monitoring your security strategy, mapping your assets, categorizing your risks, paying attention to third-party risks, and practicing incident management.
Few principles of building a strong cybersecurity posture:
1.Understanding nuisances of Data storage: No matter the size of your organization, it is important to keep an up-to-date inventory of your organization’s information assets.
2. Review and evaluate types of security risks: It might not always be in an organization’s best interest to expect the worst, but understanding the different types of security risks out there allows for proactive protection against such risks.
3. Evaluating security of organization’s vendor: While it might be obvious to assess company-built tools or those used specifically to store sensitive corporate data, all vendor platforms that touch your networks and/or process sensitive data should also be evaluated.
4. Prioritize security risks: Once you’ve listed, reviewed, and analyzed potential security risks, prioritizing them will allow you to take action. With the most critical risks identified, you can put time and resources into eliminating or mitigating those risks before an attack or breach can occur.
