blockchain

computer fraud

Any type of fraud that requires computer technology to perpetrate.

password cracking

Recovering passwords by trying every possible combination of upper and lower-case letters, numbers, and special characters and comparing them to a cryptographic hash of the password.

dictionary attack

Software that generates user ID and password guesses using information about the targeted company and a dictionary of possible user IDs and passwords to reduce the number of guesses required.

social engineering

The techniques or psychological tricks used to get people to comply with the perpetrator’s wishes in order to gain physical or logical access to a building, computer, server, or network. It is usually to get the information needed to obtain confidential data.

what are the 6 steps of computer fraud

1. Conduct reconnaissance

2. Attempt social engineering0.

3. Scan and map the target

4. Research

5. Execute the attack

6. Cover tracks

log analysis

The process of examining logs to identify evidence of possible attacks.

intrusion detection systems (IDSs)

Systems that create logs of all network traffic that was permitted to pass the firewall and then analyze those logs for signs of attempted or successful intrusions.

honeypot

A decoy system used to provide early warning that an insider or outsider is attempting to search for confidential information.

computer incident response team (cirt)

A team responsible for dealing with major security incidents.

penetration test

An authorized attempt to break into the organization’s information system.

which one has a centralized system? Traditional or blockchain?

traditional

which one requires a middleman? traditional or blockchain?

traditional

which one has a distributed ledger? traditional or blockchain

blockchain

which one has multiple copies? traditional or blockchain

blockchain

Information cannot be added or deleted without the

knowledge of the entire network. is this traditional or blockchain?

blockchain

when is a blockchain useful?

• Enable multiple parties that do not fully trust each other to

collaborate with a shared source of truth.

• Accelerate transaction settlement and verification by eliminating

intermediaries.

• Help cut costs that would be spent on manual verification (help

auditors collecting & evaluating evidence to support

transactions)

define consensus. Is consensus referring to traditional or blockchain?

all parties will be aware of transactions that take

place on the network and agree to the transactions being written

to the blockchain.

proof of stake

A set of validators who propose the next block lock up an amount of their cryptocurrency as

a deposit to ensure honest behavior.

• It reduced computer costs and centralization risks.

proof of work

ll miners compete to create the next block to be committed to the blockchain. This is done

by solving a complex mathematical problem.

• It requires the miners use computer power so it can prevent attacks as it requires tons of

computer powers to overcome.

proof of authority

The administrator identities who creating blocks are known and reputable.

The rest of the network can vote for admin removal in case of malicious behavior found in the network.
