    Study Notes

    Computer Security & Risks

    • Computer security is crucial for protecting systems and information.
    • Risks include intruders and security incidents.
    • Backups and protection are essential.
    • Policy and procedures are needed.
    • Technology and authentication are important.
    • Access control can be implemented via software.
    • User authentication can be multi-faceted (something you know, something you have, something you are).
    • Strong passwords are critical for restricting access. Passwords should include numbers, symbols, upper and lower case letters. Do not use easily guessable passwords.
    • Passwords should be changed frequently.
    • An administrator account is required to install additional software and modify system settings.
    • Access control software is used to manage user privileges and access.
    • Firewalls are used to filter information between a system and the internet, protecting against hackers.
    • Firewalls can be software or hardware.
    • Encryption scrambles transmitted messages to secure them using a secret code (key).
    • Decryption is the process of retrieving the original message from an encrypted message.
    • Anti-virus software helps protect computers and files from harm and detects, then deletes viruses.
    • Anti-virus software must be regularly revised to respond to new viruses.
    • Audits help monitor and document user activity and are important for detecting suspicious activity.
    • Uninterrupted power supplies (UPS) protect data loss due to power failures.
    • Surge protectors shield electronic equipment from power spikes.
    • Backups are used to retrieve data from original data/file, which is most often important.
    • Incremental backups only copy new files or modified files.
    • A complete system backup is made in case of a crash (typically weekly, or after new software installations).
    • Safe computing practices, such as backing up data, locking sensitive files, utilizing strong passwords, and being cautious about email attachments and suspicious links.
    • Security measures can threaten privacy.
    • Smart badges use broadcast identification codes, and location databases record badge/person location data.
    • Smart phones utilize proximity recognition technology.
    • Cybercrime laws (like UAE Law No. 5 of 2012) make cybercrime offenses more punishable and serious.
    • Software bugs can cause more damage than viruses.
    • It is impossible to eliminate all software bugs.
    • The larger the system, the more likely the system has more bugs.
    • Cyber warfare is a type of warfare that utilizes technology to attack computer networks and cripple telecommunications, power grids, and water/gas supplies.
