Network Security Issues

Front

Phishing

Back

Emails that try to trick users into giving away personal details. The phishing email pretends to be a genuine message and tries to deceive the user into following a link to a website that looks like the real company, for example, a bank. However, it is a fake website designed to catch data such as bank account numbers and security codes.

Front

Brute force

Back

Where a program is used to find a password by trying all possible combinations of characters until the correct one is obtained.

Front

Denial of service (DOS)

Back

Where a computer (or many computers) is used to prevent a server from performing its tasks. This is done by bombarding the server over and over again with requests. Eventually the server is tied up trying to handle all the DOS requests, making it very difficult for it to respond to legitimate requests.

Front

Data interception and theft

Back

Where data is intercepted during transmission. This is done using software called a packet sniffer, which examines data packets as they are sent around a network, or across the internet. The information gathered is sent back to a hacker.

Front

Structured query language (SQL) injection

Back

Where SQL code is entered as a data input. Many databases use SQL code to interrogate the data and maintain the structure. SQL code can be inputted as data, which can cause errors or unintended operations.

Front

Poor network policy

Back

Where a network does not have security rules in place for users to follow.
