The blockchain has shown to be an incorruptible and highly transparent technology. It delivers end-to-end encryption and security because of its decentralized nature. The distributed nature of blockchain removes the possibility of human mistakes and protects against hacker assaults. This is crucial for access control, especially as a service.
Blockchain technology generates a data format with intrinsic security properties. To maintain the integrity of transactions, it relies on
- Encryption
- Decentralization
- Consensus
Each block of data in most blockchains or distributed ledger technology (DLT) comprises a transaction or bundle of transactions. Each new block in a cryptographic chain is connected to the previous blocks, making tampering almost tricky. A consensus system verifies and approves every transaction within a block, guaranteeing that every transaction is accurate.
Blockchain technology facilitates decentralization through the engagement of network participants. No one person or system compromises the integrity of the ledger of financial dealings, and no one user alters the history of those dealings. Yet, distributed ledger systems vary in essential security features.
How blockchain security varies by the kind
Participation and data access rules in blockchain networks are flexible. Public, private, permissioned, or permissionless networks explain who can join and how.
Private and public blockchains
Typically, anybody joins a public blockchain network, and individuals stay anonymous. A public blockchain relies on internet-connected computers for transaction validation and consensus formation. In the case of Bitcoin, the most well-known public blockchain, a consensus is reached through a process known as bitcoin mining. Machines on the Bitcoin network referred to as miners, attempt to solve a complicated cryptographic challenge to generate proof of work and confirm the transaction. Apart from public keys, this network form has few identification and access constraints.
Private blockchains usually allow only well-known entities to join and use identification to validate membership and access privileges. Collectively, the groups constitute a business network exclusive to members. A private blockchain on a permissioned network reaches an agreement using a process known as selective endorsement, in which recognized users validate the transactions. Only members with certain rights and access manage the transaction ledger. This sort of network requires increased authentication and access constraints.
While developing a blockchain-based application, it’s essential to determine which network type best serves your business objectives. Private and permissioned networks are strictly monitored and preferred for compliance and regulation. Further decentralization and dissemination, however, is possible on public, permissionless networks.
- Public blockchains are open to anybody who wishes to join and validate transactions
- Private blockchains are often restricted and reserved for commercial networks. A single corporation or consortium governs membership
- On permissionless blockchains, there are no processor restrictions
- Permissioned blockchains are restricted to a chosen group of users whose identities are granted by digital certificates
Cyberattacks and Fraud
Blockchain technology creates an unaltered transaction ledger, but blockchain networks are still vulnerable to hacking and fraud. Individuals with malicious intent exploit known blockchain technology weaknesses and have succeeded in various hacks and scams.
How Cybercriminals Exploit Blockchain Technology
Hackers and scammers pose four critical threats to blockchains:
- Phishing
- Routing
- Sybil
- 51% assaults
1. Phishing attacks
Phishing is an effort to get a user’s credentials fraudulently. Fraudsters’ emails sent to wallet key owners appear to originate naturally. The emails request users’ credentials by using deceptive hyperlinks. Accessing a user’s passwords and other sensitive data costs the user and the blockchain network.
2. Routing attacks
Blockchains depend on massive, real-time data transmission. As data is being sent to internet service providers, hackers intercept it. Blockchain players are often unaware of a routing attack’s danger, so everything appears fine on the surface. Yet, criminals have grabbed private data or currency behind the scenes.
3. Sybil attacks
A Sybil attack is one in which cybercriminals generate and employ many fictitious network identities to overwhelm the target network and cause a system crash. Sybil is a well-known literary character with multiple personality disorders.
4. 51% of attacks
Particularly for large-scale public blockchains, mining demands massive processing power. But, if a miner or group of miners amassed sufficient money, they obtain more than fifty percent of the mining power of a blockchain network. Possessing more than half of the power implies you have influence over the blockchain and alter it. Yet, private blockchains are immune to 51% of assaults.
So, in today’s digital world, it’s crucial to take measures to protect the safety of both your ledger design and surroundings.
While developing an enterprise blockchain application, address security at all tiers of the technological stack and handle network governance and permissions. Using tried-and-tested security measures and those exclusive to blockchain technology is essential for protecting any corporate blockchain system. Among the various security controls for business blockchain platforms are the following:
- Identity and access management
- Key management
- Data privacy
- Secure communication
- Smart contract security
- Transaction endorsement
Hire professionals to assist you in designing a compliant and secure system and achieving your company objectives. Consider a production-ready blockchain solution development platform that can be implemented on-premises or with your chosen cloud provider.
Access control through blockchain
By applying blockchain access management, several blockchain-powered firms are attempting to improve corporate security dramatically. Their objective is to survive security difficulties and provide the end user authority over the data.
What does identity access request management mean
Identity and access management, also known as IAM, generates and administers individual network entities’ roles. It also manages access rights to several cloud-based and on-premises apps. Users are the following:
- Customers
- Partners
- Workers
Some devices include:
- Laptops
- Mobiles
- Modems
- Servers
- Controllers
Managing, updating, and keeping tabs on every user’s or device’s digital identity is essential throughout their access session. Hence, the fundamental objective of IAM systems is to create a distinctive digital identity for each individual or object.
What are identity management and access request control tools
Businesses use identity and access request management systems to manage and provide access to employees. Organizations of all sizes use IAM systems to allow users access to secure apps and services. IAM solutions allow security managers and administrators to track, limit, and monitor data access.
The best part is that IAM software lets you configure and monitor all these permissions from your computer on an internet platform.
What benefits do IAM technologies offer?
Companies employ IAM systems to protect and control user activity and application access. In addition to this well-known benefit, the following are other benefits:
- With IAM technologies, administrators modify access privileges
- With high-efficiency features like SSO and MFA, the user and the company needn’t be concerned about data breaches or other security concerns
- It enables you to control who has access to your data and how it’s used and shared
- IAM decreases spending on IT
