    Study Notes

    Digital Security, Ethics, and Privacy

    • A digital security risk is an event or action that could damage or lose computer or mobile device hardware, software, data, information, or processing capability.
    • Types of digital risks include threats to information, physical health, mental health, and the environment.
    • Cybercrime is an intentional breach of digital security, often a deliberate illegal act involving computers or related devices.
    • Crimeware is software used by cybercriminals.
    • Digital forensics (cyber-forensics) involves discovering, collecting, and analyzing evidence found on computers and networks. This includes examining media, programs, data, and log files on computers, mobile devices, servers, and networks.
    • A digital forensics examiner needs law knowledge, technical skills in hardware and software, excellent communication, familiarity with corporate structures/policies, willingness to learn, and problem-solving skills.
    • Digital detox is refraining from technology use for a specific time, which can help with behavioral health, including better sleep, less anxiety, and better thoughts. It can also alleviate physical problems like eye strain and repetitive stress injuries.
    • Threat actors are thieves who attack other users and computers.
    • The Dark web is a part of the internet that's accessed through specialized software, letting users and website operators remain anonymous while performing illegal actions.
    • Script kiddies are individuals who lack computer and network knowledge but attempt computer attacks by downloading freely available software.

    Internet and Network Attacks

    • Internet attacks include malware, botnets, denial-of-service (DoS) attacks, backdoors, and spoofing.
    • Spyware secretly collects user information and communicates it to outside sources.
    • Worms are programs that repeatedly copy themselves, using up resources and potentially shutting down computers, devices, or networks.
    • Backdoors in programs let users bypass security controls to access programs, computers, or networks.
    • Denial of service attacks flood servers with network traffic, preventing them from functioning.
    • Firewalls protect network resources from outsiders.
    • Biometric security uses unique characteristics like face, hands, or eyes to authenticate users.
    • Content filtering restricts access to specific material.

    Input Devices

    • Voice input involves speaking into a microphone.
    • Motion-sensing devices use wired or wireless technology to translate player movements into input.
    • Optical scanners convert printed text and graphics into a form computers can process.
    • OCR converts scanned images to digital text for editing and searching.
    • QR codes are 2D bar codes that store information in both vertical and horizontal directions.
    • MICR readers read text printed with magnetized ink.
    • Magstripe readers read the magnetic stripe on cards to identify information and card issuers.
    • Inkjet printers spray ink onto paper to form characters and graphics.
    • Thermal printers use heated pins to make images on heat-sensitive paper.
    • Digital cameras can use touch input.
    • Foot mice use feet to control a computer.
    • Styluses are small metal or plastic devices that look like pens.

    Storage Devices and Data

    • Data projectors display computer information on a larger screen.
    • Cloud storage keeps files on servers on the internet.
    • Storage time is the time required to access items from storage media.
    • Zettabytes are a large unit of digital measurement.
    • Solid state drives (SSDs) are flash memory storage devices containing their own processors. They have faster access times, transfer rates, and are more durable than traditional hard drives.
    • RAID (redundant array of independent disks) duplicates data and information to improve reliability.
    • RAM (random-access memory) is volatile, requiring power to maintain content. Head crashes cause computer disk damage, and CD-RWs are erasable multisession discs.
    • SAN (storage area networks) are high-speed networks designed to provide storage to other servers.
    • RFID tags are chips containing information transmitted via radio waves.

    Other Technologies

    • SDHC cards are high-capacity storage cards commonly used in cell phones.
    • Signature capture pads record electronic signatures.
    • Formatting a hard disk involves erasing all existing data to prepare it for use.
    • DVD or Digital Versatile Discs store large amounts of data.
    • Smart TVs have Internet access enabling web browsing, streaming, and other online activities.

    Operating Systems and Software

    • Linux is a Unix-like, open-source, and community-developed OS for computers, servers, mainframes, etc.
    • File managers allow users to organize and manipulate files and folders.
    • Multi-user operating systems let multiple people access the same system concurrently.
    • Real-time operating systems manage tasks with strict timing requirements.
    • Device managers help a computer's users view, configure, and manage hardware devices.
    • Memory managers allocate and track computer memory.
    • Network operating systems manage network resources and communication.
    • Process managers oversee processes and threads in operating systems.
    • Virtualization allows multiple OSs to run on a single server simultaneously.
    • MacOS is a proprietary graphical OS for Apple products.
    • Web filtering software monitors and controls internet access by users.
    • Crowdsourcing gathers information, work, or opinions from numerous individuals.
