Knowledge of the following:

Viruses, worms, spyware and other types of malicious software fall under the category of malware. It is the action of clicking on a malicious link or attachment on a webpage that activates malware, which then leads to the installation of dangerous software on your computer. As per Cisco reports, malware can be used in the following ways once it has been activated:

• The blockage of key components of the network (ransomware)
• The installation of additional harmful software
• Transmit data from the hard drive in order to obtain information covertly (spyware)
• The system is rendered inoperable as a result of disruption of individual components

Knowledge of the following:

• According to the Cybersecurity and Infrastructure Security Agency (CISA), Emotet “is a highly sophisticated, modular banking Trojan that primarily functions as a dropper or downloader of other banking Trojans that appears to be related to banking. As a result, Emotet has been consistently classified as one of the most destructive and costly malware programs.”

Knowledge of the following:

• DoS: Denial of Service cause computers and networks to be unable to respond to requests. An attack originating from a computer network is called a distributed DoS (DDoS). 
• Flood Attacks: It is common for cyber attackers to perform a DoS through the use of a flood attack. Cyber attackers may employ several other techniques, and some are able to launch other attacks during the period when the network is down. 
• Botnets: A botnet, sometimes also referred to as a zombie system, is part of a network whose goal is to overwhelm the processing power of its target. There are many botnets located all around the world, making it nearly impossible to identify them.

Man-in-the-middle Attacks: When hackers manipulate a two-way interaction between two parties in order to gain access to sensitive data by filtering and stealing data after interrupting the traffic they are feeding through

Knowledge in the following: 

• Attacks that are carried out by using fake communication, such as an email, to trick the recipient into opening the email and doing what it instructs them to do, including providing their credit card information.

Knowledge in the following:

• The injection of Structured Query Language (SQL) into a server, which is one of the most common types of cyber attacks, results from insertion of malicious code into the database of the server. Infected servers release information when they become infected with a virus.

Knowledge in the following: 

Social Engineering: It is common for cyber attackers to use social engineering techniques as a form of password attack, and Data Insider defines it as a strategy in which attackers use people to trick them into breaking standard security procedures. In addition to accessing a password database or guessing the password outright, there are other types of password attacks.

Knowledge in the following:

• Access points for hackers exist in devices that connect to the internet or other networks. According to a report by Cytelligence, hackers redirected their attention to smart homes and IoT devices in 2019, such as smart TVs, voice assistants, connected baby monitors and smartphones, as well as smart homes and IoT devices. 

Knowledge in the following: 

• Cyber attackers are more likely to find an entry point into a network if they can gain access to personal devices such as laptops and cellphones which store data, as these small devices are easy to access.
