The ability to securely store and communicate sensitive data 
has proven to be a vital aspect of all firms’ success. 
Cryptography is the process of protecting data using techniques 
that ensure its integrity, secrecy, validity, and non-repudiation 
and the recovery of encrypted data in its original form. This 
article will cover the fifth domain of SSCP: Cryptography and 
what you can expect in the SSCP exam from this domain.

Domain 5: Cryptography
Domain 5 of the SSCP certification exam is Cryptography. The 
Cryptography domain comprises a weightage of 10% in the Systems 
Security Certified Practitioner (SSCP) certification exam. This domain 
will overview the concepts and requirements of confidentiality and 
how to achieve it with cryptographic methods. Confidentiality is a 
crucial responsibility of all IT security personnel. This section will go 
over cryptographic techniques, key usage, and the different types of 
cryptographic systems. You will learn that public-key infrastructure is 
used every time someone logs into an e-commerce site. It will go 
through how to use digital certificates, ensure data integrity, and what 
techniques can be used to safeguard data while at rest or in transit. 
The domain will teach how to use cryptographic measures to give 
authentication. It will also cover non-repudiation to assure that the 
sender of a message cannot deny that they sent it. The subtopics 
covered in the Cryptography domain are:

 Understand reasons and requirements for cryptography
 Understand and support secure protocols
 Understand Public Key Infrastructure (PKI) systems

1. Understand Fundamental Concepts of Cryptography
This subsection will provide an overview of the fundamental terms 
and concepts of cryptography. Cryptography is the practice and 
study of ways for securing communications while third parties are 
present. It will address encryption techniques for securing sensitive 
data, ensuring data integrity and authenticity, and establishing 
non-repudiation and proof of message origin. It will cover the 
difference between hashing and encryption and go over symmetric 
and asymmetric cryptography. It covers the two basic encryption 
methods, symmetric and asymmetric encryption. It will teach 
about how various cryptographic algorithms work and how RSA 
works. It will also cover multiple terms such as non-repudiation, 
digital signatures, digital certificates, and proof of origin. The 
section will also go over cryptographic attacks, concepts of 
cryptanalysis, and countermeasures to protect sensitive data from 
unauthorized access.

2. Understand Reasons and Requirements for Cryptography
This subsection will cover data confidentiality, integrity, and 
availability, as well as authenticity and non-repudiation. A secure 
system should guarantee these. Cryptography can assist in providing 
these assurances when utilized effectively. Data in transit and data at 
rest are protected by cryptography, ensuring their confidentiality 
and integrity. It will also teach about using cryptography to protect 
against repudiation by establishing trust between senders and 
recipients. This section will discuss how an unauthorized exposure of 
that information would affect any organization’s confidentiality, 
integrity, or availability. Sensitive data is confidential data that must 
be kept safe and out of the hands of anyone who does not have the 
authorization to see it. This section will also address cryptography 
regulations designed to protect individuals and organizations from 
having their personal information shared without their permission.

3. Understand and Support Secure Protocols
This subsection will cover various services and protocols to secure data. A secure 
protocol is a set of operations that ensures data security. The section will discuss 
how cryptographic protocols like SSL/TLS protect communications from harmful 
eavesdropping and tampering by providing confidentiality and integrity 
guarantees. The area will cover common use cases. It will also cover various 
limitations and vulnerabilities of the services and protocols used in cryptography.
4. Understand Public Key Infrastructure (PKI) Systems
This subsection will go over fundamental key management concepts, key 
administration and validation, and Public Key Infrastructure (PKI) systems. The 
control of cryptographic keys is referred to as key management in a cryptosystem. 
It covers the key generation, exchange, storage, use, crypto-shredding 
(destruction), and replacement. Cryptographic protocol design, key servers, user 
procedures, and other vital protocols are also covered. This section will also go 
over the Web of Trust (WOT) to help determine which websites are safe or not. 
WOT will protect from frauds, malware, phishing, and identity theft. It will cover 
Pretty Good Privacy (PGP), Gnu Privacy Guard (GPG), and more.
