Cryptography as a Section in the CompTIA Security+ Certification Test

CryptographyCryptography is part of the globally renowned CompTIA Security+ certification test. This is understandable due to the growing number of threats to network security. According to a computer science research by a faculty at Yale University, addressing security threats would require a mix of legal, technical, and social approaches. Thus, a thorough knowledge of cryptography is useful.

What Is Cryptography?

Cryptography comes from a mix of two words. One is cryptos – a Greek word that means secret. The other is graphy – a suffix that denotes a science. If you combine these two words, they would suggest that cryptography means “a science of keeping matters secret”.

And that’s exactly what cryptography is. To accomplish matters in line with science, mathematical modeling, security properties, and distributed algorithms are necessary. You can also learn about this from a Security+ study guide and also a CompTIA Security+ practice test.

Cryptography & Its Functions

An important aspect of cryptography is its security functions. These basic functions are integrity, non-repudiation, confidentiality, and authentication. It is through these security functions that network and information security are provided.

The goal of these security functions is to give assurance and verification to the transfer of important data. These functions address the concerns of data transfer to networks. They ensure that data transfer is uncorrupted and done successfully.

Why Study Cryptography?

As one of the test’s six domains, the CompTIA Security+ test will tackle concerns regarding cryptography. To pass the test, and earn Security+ certification, reviewing lessons on cryptography is best. You should also consider taking a CompTIA Security+ practice test.

Conclusion

Alongside being able to pass the CompTIA Security+ certification test, knowledge on cryptography is beneficial. A Security+ certification paves the way for more promising career opportunities in the IT industry (such as those for data security). More importantly, you also gain an employer’s confidence as a certified professional.

By learning about cryptography, you will also be learning about cryptanalysis. This means you can create strong cryptosystems. In turn, you can use these cryptosystems to raise the security for your network.
