Study Notes
Cyber Security
- Cyber security refers to the protection of information systems, data, and services from unauthorized access, harm, or misuse.
- Protection includes harm caused intentionally by the system operator or accidentally due to failing to follow security procedures.
Information Security
- Information security is the preservation of confidentiality, integrity, and availability of information.
- Additional properties involved in information security include authenticity, accountability, non-repudiation, and reliability.
Malware
- Malware is a generic term for software with a malicious purpose.
- Types of malware include viruses, worms, adware, Trojan horses, and spyware.
- Viruses are small programs that replicate and hide themselves inside other programs, usually without the user's knowledge.
- Viruses can cause network slowdowns due to heavy network traffic caused by replication.
- Trojan horses are electronic programs that appear to be benign but secretly download malware onto the computer.
- Spyware is software that tracks a user's activities on their computer, including browsing history.
- Logic bombs are software that lay dormant until a specific condition is met, then perform malicious acts.
- Key loggers record all keystrokes and can take periodic screenshots of the computer.
Security Breaches
- Security breaches include any attempt to gain unauthorized access to a system.
- Examples of security breaches include cracking passwords, elevating privileges, and breaking into a server.
- Cracking is the act of intruding into a system without permission, usually with malevolent intent.
- Social engineering is a technique for breaching a system's security by exploiting human nature rather than technology.
- War-dialing and war-driving are techniques used to gain entry to a system by calling phone numbers or locating vulnerable wireless networks.
