Introduction
Hyperledger Fabric is a blockchain platform
designed for enterprise environments. It is a
permissioned platform that provides privacy and
confidentiality for transactions.
Despite the security improvements Hyperledger
Fabric provides, deployments still require careful
configuration and monitoring to ensure they
operate securely.
Here, we will examine different threats that
Hyperledger Fabric operators should consider
and discuss how to mitigate them.

What Are the Security Threats
in Hyperledger Fabric?
These are the critical security threats in Hyperledger Fabric -
Denial of
Service (DoS)
MSP
Compromise
Consensus
Manipulation
Private Key
Attacks
Smart Contract
Encryption

Denial of Service (DoS)
A Denial-of-Service (DoS) attack shuts down a
network or a machine, making it inaccessible to
its intended users. Usually, it interrupts the host
temporarily, connected to the internet.
Mainly, these attack credit card gateways, banks,
etc. Triggering many advertisements on the web
page requests creates a load on the web server.

Mitigation
Monitor and analyze
network traffic
Boycott using
third-party websites

MSP Compromise
This threat attacks the blockchain network to
lock the credential information. The attacker
will ask for money, known as ransomware, in
exchange for data.
The data might be encrypted that will unlock
only with a specific crypto key. It is like
locking an owner in the house and asking for
money to unlock it.

hardware configurations
Increased
Bandwidth

Consensus Manipulation
Hyperledger Fabric uses Crash Fault Tolerant (CFT)
consensus algorithms. For this, it can't accept any
malicious threat. Currently going on Byzantine
fault Tolerant (BFT) algorithms, it can accept up to
1/3 malicious of the existing network.
But with the consensus algorithms, early virus
detection can mitigate this threat.

Private Key Attacks
The cryptocurrency consists of public and private
keys that must encrypt and decrypt the data.
They are meant to be handled securely and
effectively.
If a public key gets exposed by the attacker will
lead to having a private key used to decrypt the
data. The attacker can easily decrypt and can
steal or manipulate the information.

Smart Contract Encryption
In cryptocurrencies, where Hyperledger Fabric
can compromise enterprise logic and network
execution, the attack on smart contracts is easier
than others.
Also, common errors can occur from handling
concurrency. The app must be considered for
outer security. With this, the performance and
use of the smart contract should be observed
once deployed to detect strange behavior.

Common Mitigation Strategies
Here are some common mitigation strategies you can
follow to prevent security threats -
Preventive benchmarks to mitigate these security
threats are components of a secure deployment.
It is vital to observe the arrangements and security
of the P2P network constantly.
Many threats can be caught by connecting data
across the blockchain P2P network, threat brilliance,
and association infrastructure.

What Do the Threats Do?
Threat Indicators Data Source
DoS
Slow down network
performance
Heavy traffic to a network
server
MSP Compromise
No access to the
user’s data
Exploit phishing
Consensus Manipulation
Reduce dependency, faith,
and responsibility of nodes
connecting to a network
Reduce the proof of
work mechanism
Private Key Attacks
Unwanted transactions,
encryption, and decryption
occur
Financial details of
businesses
Smart Contract Encryption Costs millions of dollars
When a contract transmits
ether to an anonymous address

Bottom Line
Proactive measures to mitigate these security threats are part
of a secure deployment. It is vital to monitor the network's
performance and security continuously.
These threats can only be detected by correlating data across
the blockchain network, company infrastructure, and threat
intelligence providers.
