Study Notes
Privacy Rights and Measures
- Privacy rights are under increasing threat, necessitating diverse measures like legislation, enforcement, and self-help mechanisms to protect individuals and consumers from privacy violations and legal implications.
- Invasion of privacy is defined as wrongful entry, seizing, or acquiring possession of another's property.
Privacy Violations
- Misuse of information is a common violation of privacy, where collected data is sold to the highest bidder, constituting an unauthorized use of personal information.
Physical Access Controls
- Physical access controls are necessary to ensure physical security, involving both physical barriers and electronic protocols to authenticate users.
- Physical barriers include fences, brick walls, natural trees, mounted noise or vibration sensors, security lighting, closed-circuit television (CCTV), and buried seismic sensors.
- Electronic access controls include card access control systems, firewalls, and passwords.
Password Security
- A password is a string of characters used to verify a user's identity to an information system facility.
- Password security relies on the user observing four "never" rules: never publicize a password, never write it down, never choose an easily guessable password, and never keep the same password for an extended period.
Firewalls
- Firewalls are used to isolate sensitive portions of an information system facility from the outside world, limiting potential damage from malicious intruders.
- There are three main types of firewalls: packet filters, proxy servers, and stateful inspection.
Anonymity on the Internet
- The internet provides a fertile ground for anonymous acts, with its lack of political, cultural, religious, and judicial boundaries.
- Anonymity on the internet is achieved through anonymous servers and anonymous users.
- Anonymous servers can be classified into two types: full anonymity servers and pseudonymous servers.
Internet Security
- Integrity is a crucial aspect of internet security, ensuring that unauthorized modification of files is prevented, and the status quo is maintained.
- Security availability involves preventing unauthorized withholding of information from those who need it when they need it.
- Physical security is guaranteed by implementing four mechanisms: deterrence, prevention, detection, and response.
