What do Cybersecurity analysts do in Cryptography? Each day, this world of data breaches and cyber attacks is becoming more dangerous. Then what can be said about the cybersecurity analyst?
What do Cybersecurity analysts do in Cryptography?
Cryptography is one of their most precious tools, and here we discuss what exactly such professionals do with cryptography. For this, we delve into what role such professionals play in using and managing cryptography to protect sensitive information in this article.
What is Cryptography?
Cryptography is the art and science of securing communication. It generally means encoding information so that only certain parties can understand or gain access to it.
Cryptography finds its origins thousands of years back, and even the most ancient civilizations were using some form of primitive secret writing.
Cryptography has today become a very complex field offering techniques that include encryption, decryption, hashing, and digital signatures.
All these techniques provided a base to secure the individual information, data integrity, and confidentiality, as well as protection from unauthorized access.
Role of Cybersecurity Analyst:
A cybersecurity analyst assures the safety of an organization’s digital infrastructure against cyber attacks. Encryption happens to be in their list of weapons where they can protect their data from unauthorized access by implementing security measures.
Analysts tend to apply cryptographic techniques for encrypting some information, managing cryptographic keys, and evaluating the levels of security encryption protocols present.
But why is cryptography so important in their job? In a nutshell, cryptography forms the backbone of data security. Without this, all other safety measures are easily breached.
How Cryptography is Used in CyberSecurity:
Cybersecurity cryptography has several utility purposes:
Protecting Data Confidentiality:
Cryptography ensures that data becomes readable only by those who have the right decryption key. This limits hackers’ access to sensitive information even though they infiltrate other layers of defence.
Safety of Data:
Hashing is one form of cryptography that verifies or proves a message being sent over a given medium has not been altered.
Authentication:
Cryptography is primarily needed for the authentication of user and system identities. In short, it becomes essential to determine whether only legitimate entities are allowed access to specific resources.
Daily Job Duties of Cybersecurity Analyst in Cryptography:
To an analyst working in cybersecurity, cryptography does not represent theory; it becomes a part of the daily. Some of the most common responsibilities include:
Encryption and Decryption:
Analysts will sometimes encrypt private data that reside or are being transmitted. Decryption takes place when access authorization is required.
Key Management:
Keys employed in encryption will be created, distributed, and stored. If such keys end up in the wrong hands, then encryption really serves no point at all, so proper key management is a concern of analysts.
Cryptographic Protocols:
Analysts will implement secure protocols, such as SSL/TLS, to ensure the safety of internet communications.
Threat Analysis and Cryptographic Vulnerabilities:
They monitor vulnerabilities in existing cryptographic systems and stay ahead of emerging threats.
Encryption: The Heart of Cryptography
Encryption is generally the process of changing readable data or plaintext to a format that is unreadable, known as ciphertext. That is essentially what cryptography is all about.
A cybersecurity analyst needs to be able to manage and apply encryption in such a way that it does not impede the usability of the data but offers protection instead.
Symmetric Encryption:
It uses a single key for encryption as well as decryption. In this method, the problem lies in transmitting the key between parties safely.
Asymmetric Encryption:
Here, a pair of keys is utilized the public key is used to encrypt and the private key is for decryption. This is widely used during the process of secure communication that is, for example, while encrypting emails.
Public Key Infrastructure (PKI) and Importance:
PKI stands for the infrastructure through which asymmetric encryption is able to be used to enable secure communication over a network that you do not trust.
Additionally, PKI ensures the distribution of public keys via trusted channels. Cybersecurity analysts work in a few roles in PKI management.
Cybersecurity analysts ensure that digital certificates are valid and secure. This is a type of validation for public keys and forms the foundation of PKI management, which is critical when sensitive information is involved, such as in an e-commerce or online banking transaction.
Digital Signatures and Hashing:
Digital signatures use cryptographic techniques to verify and validate that a message or document is authentic and has not been altered. Hashing takes data and converts it into a constant-size string or, as it is properly called, a hash; this string provides for the uniqueness of the data itself.
The Cybersecurity Analyst Uses Digital Signatures and Hashing:
- To ensure the integrity of data in transport, so it was not changed during transport
- To verify the authenticity of digital documents
Some hashing algorithms commonly utilized are SHA-256 and MD5, and this is an algorithm that an analyst should know about.
Key Management and Distribution:
Cryptographic key management is considered one of the toughest issues in cryptography. The strength of a whole encryption system determines how its keys are protected. The duties of cybersecurity analysts include:
- Keeps keys safe from unauthorized access.
- Distributes keys in such a way that confidentiality and integrity should not be breached
Change keys frequently, which could lead to possible compromise.
Cryptographic Vulnerability Analysis:
No cryptosystem is flawless, and cyber attackers continually seek vulnerabilities in every aspect. Cybersecurity analysts have to:
Identify Old Algorithms:
Such algorithms as DES are very old and insecure; these need to be replaced by strong ones like AES.
Real-Life Attack Analysis:
The study of cryptographic attack analysis, such as side-channel attacks or brute-force attacks, can improve them.
Prevention:
This includes patching up the vulnerable cryptographic libraries and making sure that secure encryption standards are in place.
Cryptographic protocols used by Cybersecurity Analysts:
There are several cryptographic protocols which a security analyst would very often apply, including SSL/TLS, which secures data sent over the web like in the example of a channel above (Channel), and IPsec to protect communication in the implementation over IP networks. A cybersecurity analyst must monitor and update these protocols against vulnerabilities.
- Trace down the cause of a breach by conducting forensic investigations.
- Deal with a compromise of a cryptographic system, for example, how to re-encrypt data using new keys.
Regulations and Standards for Cryptography:
Cryptography is very standardized by government-standard frameworks and standards.
Examples include:
- FIPS (Federal Information Processing Standards)
- AES (Advanced Encryption Standard)
Cybersecurity Analysts should ensure the organization maintains compliance with such standards to avoid risks of fines and ensure adequate protection of its data.
Skills and Tools for the Cybersecurity Analyst’s Job in Cryptography Work:
Cybersecurity analysts performing cryptography work will need the following skills and tools in their job.
Tools:
The testing and management of cryptographic systems imply the use of tools such as Wireshark, OpenSSL, and Kali Linux.
