Digital assets are the boons to today’s world of earning passive income! We need to keep them safe from malwares, phishing attempts or scams. It is of paramount importance to implement strong security measures like using safe wallets, staying informed about the potential threats to keep currency risk-free.
1. What is cryptocurrency security?
It is of utmost importance to keep the cryptocurrency secure from potential theft, unauthorized access or fraudulent activities. It includes strategies like secure key management, multi-factor authentication,and encryption to prevent any possible crypto alteration. In this chapter, we will scroll through the basics of securing your crypto!
1.1. Definition
The practice of incorporating technologies and safety protocols to safeguard the digital assets, online transactions and unauthorised access to the sensitive information is called cryptocurrency security.
1.2. Why is cryptocurrency security important?
Protecting our crypto from theft and frauds is very crucial. Here’s why we need to pay way more attention to cryptocurrency security:
- For the protection of assets which have monetary value and are termed as investments.
- To prevent potential frauds and scams from causing crypto damage.
- To protect the privacy of personal and financial information.
- To prevent the hacks and loss of funds.
- To create a long-term adoption scenario for the cryptocurrency.
2. What is cryptography?
The study of the ways to protect the security and confidentiality of all the digital transactions, information exchange and data storage included in the realm of cryptocurrencies and blockchain technology. It is the foundation for secure key management, data verification and authentication.
2.1. The basics of Encryption and decryption
We take a situation here! Suppose, you need to send a private message to a friend over the internet and you do not wish anyone else to access it. Here, you decide to use encryption which is done by following the steps like :
- You choose plain text like “Hello!”, followed by using cryptographic algorithm and encryption key to transform the plain text to ciphertext which might look like “Rhkijggbh==”.
- Send this ciphertext to the friend using a communication channel
- Your friend receives it in the form of a ciphertext and uses a decryption key to reverse the encryption.
This is how encryption makes sure that only your friend gets to see the message, thus protecting the confidentiality of the text.
Therefore, encryption is a process of converting plaintext into ciphertext or scrambled data using crypto algorithms and specific keys. Decryption is the reverse process of using a decryption key to convert ciphertext back into its original plaintext format. The ones having a decryption key can easily transform the ciphertext into readable data. These two are the key elements of secure transactions, private keys, and other sensitive data in the cryptocurrency space.
2.2. All about Hash functions and digital signatures
Hash function is an algorithm which takes an input in the form of a message and gets a fixed-size string of characters in sequence of letters. The output is known as hash value or hash digest. They are commonly used for cryptography in order to facilitate purposes like password storage or digital signatures. They are one-way functions which cannot be reversed. That is, you can not obtain the original input from the hash value.
Digital signatures are cryptographic techniques to make sure of the authenticity of digital messages. They involve a pair of keys (private and public) to secure authentication of digital documents, ensuring sender’s identity and document’s integrity.
Both hash function and digital signatures are the foundational elements of cryptography, providing security and trust in digital transactions.
2.3. Public-key infrastructure (PKI): What is it?
Public key infrastructure is a series of processes which facilitates the secure management, digital certificate utilization and public-private key pairs handling. It helps in maintaining digital identities and ensuring seamless crypto operations.
PKI is used to:
- Establish safe communication channels through encryption.
- Enable the creation and verification process of digital signatures.
- Set up secure Virtual Private Networks (VPNs) and network connections.
- Encrypt messages in the email systems.
- Support strong authentication methods for accessing applications and online services.
To sum up, PKI is a leading mechanism of securing online activities, digital identity management and confidentiality of data which travels through the internet.
3. What are the possible threats in crypto space?
Considering the volatility and newness of the crypto space in comparison to the other traditional methods of financial services, threats come along due to the lack of awareness and diligence in working with the same. We have done a brief risk analysis to understand the possible threats!
3.1. An overview of risks in the crypto space
Some key risks associated with the crypto space might be:
- They are extremely volatile leading to instant gains and losses.
- They could get stuck due to loss of funds caused by hacks, scams and phishing attacks.
- Susceptible to manipulation and price pumping due to relatively smaller market size.
- Bugs in codes which lead to security breaches due to the still evolving world of cryptocurrency.
- Mistakes in wallet management and security practices could lead to loss of funds.
3.2. Basics of hacking, phishing, and malware attacks
- Hacking in crypto space is a major concern due to the digital nature of cryptocurrencies. Exchange hacks, wallet breaches, smart contract vulnerabilities, crypto-jacking and ransomware could be the dangers to your crypto. Therefore, it is always suggested to use reputable and secure crypto exchanges and wallets. Enabling 2-factor authentication for all the accounts and regular updates of softwares can help in preventing hacks.
- Phishing is a kind of cyber attack where the attackers impersonate individuals, organisations, websites to deceive the victims and make them reveal all the private information like passwords or other financial details. Phishing attacks work by faking, deceptive communication, malicious links and attachments or redirection to fraudulent websites.
- Malware attacks troubling crypto space are very common these days. Trojans, clipboard hijackers, fake wallets, browser extensions, mining malware or phishing Trojans could harm the safe space way too much. Always use anti-virus, avoid suspicious links, check URLs before clicking and secure devices with strong pins in order to avoid such attacks.
4. Step-by-step guide to secure your crypto
The proactive steps which needs to be taken to protect your digital assets include the following:
- Always use reputable and known exchanges and wallets for investing your funds.
- Enable the two-factor authentication or 2FA for all your accounts and wallets.
- Using hardware wallets, the ones which have an offline storage, is recommended for a longer use.
- Keep your private keys secure by keeping physical copies of recovery phrases in a safe offline place.
- Keep your operating system and antivirus softwares updated with the latest security patches.
- Use a mix of strong protective shields of passwords for your devices.
- Educate yourself before entering into the crypto world. You can read here for more!
