Study Notes

Cybersecurity Risk

Identifying, mitigating, and managing cybersecurity risk is the core duty of cybersecurity to protect an organization's digital assets.
Assessing risk is a critical function of a cybersecurity organization, essential for effective policies, security implementations, resource allocation, and incident response preparedness.

Cybersecurity Risk Approaches

There are three approaches to implementing cybersecurity:
- Compliance-based security: relies on regulations or standards to determine security implementations, leading to a "checklist" attitude towards security.
- Risk-based security: identifies unique risks and designs security controls to address them, considering the organization's risk tolerance and business needs.

Types of Cyberattacks

Denial of Service (DoS)

Symptoms of a DoS attack:
- Inability to access a website
- Delay in accessing online services
- Huge delays in file opening on websites
- Increased volume of spam emails
- Degradation of performance of services
Mitigation steps:
- Routing malicious traffic
- Using load balancers to avoid heavy traffic
- Using intrusion detection systems
- Using intrusion prevention systems
- Using security firewalls
Types of DoS attacks:
- DNS server attack
- HTTP server attack
- ICMP flooding
- Network attack or buffer overflow attack
- Large name files attack
- Ping of death attack
- SYN flood attack on TCP handshake protocol
- Shrew attack

Distributed Denial of Service (DDoS)

A type of DoS attack where multiple sources of traffic are used to attack the victim server.
DDoS attack is more lethal than DoS attack.
Prevention of DDoS attacks is more difficult than normal DoS attacks.
Types of DDoS attacks:
- Connection-based application-layer attacks
- Connectionless volumetric attacks from multiple botnets
- State table exhaustion attacks
- Other techniques used in DoS attacks

SQL Injection

SQL injection is the second largest source of web application malicious attacks (21.6%).
SQL injection attacks:
- Get data from the SQL database server and send it to the hacker's computer.
Most affected fields:
- IT
- Banks and e-transaction websites
- Government websites

Spamming

Spamming is the sending of junk mails and messages in bulk without consent.
Used for spreading malware, viruses, phishing, Trojans, worms, and spyware.
Widespread form of malicious attacks used to send unsolicited messages through different modes of messaging.
Can result in severe loss and damage to public lives, societies, government systems, and other critical infrastructures.

Digital Property Misappropriation

Illegal or fraudulent use of digital resources like software and digital content without permission.
Over US$6 billion are misappropriated in the global economy annually.
Laws, patents, copyrights, trademarks, and other rules are in force to safeguard digital property rights.
Steps to safeguard digital properties include:
- Data encryption
- Digital access control
- User controls
- Others
