Study Notes

Cybersecurity Risk

The core duty of cybersecurity is to identify, mitigate, and manage cyber risk to an organization's digital assets.
Assessing risk is one of the most critical functions of a cybersecurity organization.
There are three different approaches to implementing cybersecurity: compliance-based security, risk-based security, and others.

Approaches to Cybersecurity

Compliance-based security relies on regulations or standards to determine security implementations.
Risk-based security relies on identifying the unique risk a particular organization faces and designing and implementing security controls to address that risk.

Risk Management

Different industries and professions have adopted various tactics based upon risk tolerance, size and scope of the environment, and amount of data available.
The foundational risk management process includes identifying, assessing, mitigating, and monitoring risk.

Cyberattacks

A hacker attack occurs every 39 seconds on a computer connected to the Internet, resulting in 2,244 malicious attacks every day.
Cyberattacks can take many forms, including Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks.

Denial of Service (DoS) Attacks

DoS attacks aim to make a computer or network unavailable by flooding it with traffic.
Symptoms of DoS attacks include inability to access a website, delays in accessing online services, and increased spam emails.
Mitigation steps include routing malicious traffic, using load balancers, intrusion detection and prevention systems, and security firewalls.
Types of DoS attacks include DNS, HTTP, ICMP flooding, network attacks, and TCP SYN flood attacks.

Distributed Denial of Service (DDoS) Attacks

DDoS attacks are a type of DoS attack where multiple compromised systems are used to flood a target with traffic.

Other Types of Cyberattacks

Digital or cyber vandalism involves damaging or manipulating data, computers, or networks to disrupt their intended use.
Cyberstalking involves harassing and threatening individuals or organizations through digital means.
Cyber frauds and forgery involve creating counterfeit documents and currency using digital tools.
Ransomware is a type of malware that restricts access to systems and files, typically by encryption, and demands a ransom to restore access.
