Study Notes
Importance of IT Security
- Information technology security is crucial to protect sensitive data, maintain privacy, and ensure the integrity of systems.
- Breaches can lead to financial loss, reputational damage, and legal consequences for organizations.
Prevalence of Computer Incidents
- A major factor for the high occurrence of computer incidents is increased connectivity and reliance on digital systems, making them attractive targets for attackers.
Cloud Computing
- Cloud computing involves delivering computing services (e.g., storage, processing) over the internet, offering flexibility, scalability, and reduced infrastructure costs.
Pressure on Help Desks
- Computer help desks face intense pressure to provide rapid responses due to user dependency on technology for business operations and productivity.
Complexity and Vulnerability
- Rising complexity in computing environments leads to greater vulnerabilities, as intricate systems can introduce more points of failure and potential attack vectors.
Importance of Safeguarding Data
- Protecting confidential business and customer data is vital to maintain trust, uphold compliance with regulations, and prevent data breaches.
Zero-Day Exploit
- A zero-day exploit refers to a cyber vulnerability that attackers can exploit before developers release a fix, leaving systems unprotected.
Purpose of a Virus
- Viruses are malicious software designed to replicate and spread to damage systems, corrupt data, or steal information.
Virus Disguises
- Viruses can be disguised as legitimate software, file attachments, or downloads to deceive users into activating them.
Characteristics of Zero-Day Exploit
- The defining feature of a zero-day exploit is its ability to take advantage of a vulnerability that has not yet been identified or patched by the software developer.
Rootkit Definition
- A rootkit is a type of malicious software that gives attackers remote access and control over a computer, often allowing them to hide their presence.
Purpose of Phishing
- Phishing aims to deceive individuals into providing personal information, such as passwords and financial details, through fake communications that appear legitimate.
Characteristics of Commercial Software
- Commercial software is typically developed for profit, with features including regular updates, customer support, and licensing fees.
Virus Delivery
- A virus often delivers additional malicious payloads or commands as part of the data it transmits, leading to further exploitation or harm.
Types of User Target Attacks
- Users can face various types of attacks, including phishing, malware infections, ransomware, and denial-of-service attacks that disrupt service availability.
