    Study Notes

    1.4 Security

    • Data security involves safeguarding data from unauthorized access, damage, intentional destruction, infection, or corruption. Data integrity is maintaining data accuracy during and after processing.

    Importance of Security and Data Integrity

    • Data security and integrity are crucial to prevent problems arising from data loss, theft, copying, or damage. Compromised data can cause significant issues.

    Data Loss

    • Data may be lost or damaged during system crashes, especially hard disk issues.
    • Data may become corrupted due to faulty disks, drives, or power failures.
    • Data can be lost by accidental deletion or overwriting of files.
    • Viruses can corrupt computer data.
    • Unauthorized access and deletion or modification by malicious users.
    • Natural disasters or acts of terrorism can destroy data.
    • Data is subject to alterations or deletions by employees motivated by revenge, blackmail, or betrayal.

    Data Security Measures

    • Regularly back up data to a secondary location (e.g., another building).
    • Employ anti-virus software to prevent infection.
    • Protect computers using strong passwords, thereby restricting access to data.
    • Secure important data on removable disks by storing them in locked, waterproof and fireproof safes
    • Access to sensitive data areas is restricted by using authorized personnel verification measures, like ID cards, magnetic swipe cards, or biometrics.
    • Turn off computer terminals or lock them when not in use.
    • Employ data encryption techniques to dissimulate the meaning of data.

    Accidental Data Damage

    • Accidental damage involves unintentional data deletion or modification.
    • Data can be damaged by removing important files, or amending data without proper checks.
    • Prevent accidental damage by creating backups and implementing robust data management procedures.

    Intrusion Prevention (Hackers)

    • "Hackers" are skilled programmers or engineers who exploit security loopholes in computer systems.
    • They may intentionally breach computer security through various means, including hacking into computer systems using passwords, licenses, bypassing security measures

    Types of Computer Threats

    • Viruses: Can be malicious or annoying which frequently cause malfunctions and destroy data, by stopping programs, crashing the computer, or frequent restarts.
    • Spyware: malicious software that collects sensitive information about users without permission.
    • Adware: typically annoying but can be downright dangerous if it manages to gain access to sensitive data.
    • Hackers are skilled programmers or engineers, who exploit weaknesses in computer systems

    How Does a Hacked Computer Appear?

    • Newly installed programs
    • Changes to passwords
    • Increased network activity
    • Unknown programs trying to access the computer
    • Uninstalled security programs
    • Computer performing unexpected or unusual activities

    Firewalls

    • Firewalls are computer programs or hardware devices used to protect private computer networks or individual computers from unauthorized access.
    • Firewalls manage data flow based on predefined rules to prevent offensive or unwanted data.

    Firewall Mechanisms

    • Packet Filtering: Inspect incoming and outgoing data packets for malicious characteristics
    • Proxy Servers: act as intermediaries between a web browser and the Internet, improving web performance by caching frequently used webpages and filtering out malicious content.

    Firewall Filtering Rules

    • Customize rules based on security needs and threats, including blocking specific IP addresses or ranges.
    • Specify which domains can access the systems.

    Protocols

    • Firewalls can control which systems can access various protocols like IP, SMTP, FTP, UDP, ICMP, Telnet, and SNMP.
    • Blocking specific ports on servers prevents unauthorized access.
    • Filtering data flow based on keywords to block offensive or unwanted content

    Passwords

    • Passwords should be strong (at least 8 characters, combining uppercase and lowercase letters, numbers, symbols).
    • Avoid using common words, names, or sequences.
    • Change passwords regularly.
    • Do not share passwords with others.

    Biometric Passwords

    • Biometric passwords use physical characteristics like fingerprints, iris, handwriting, etc.
    • This system translates unique traits into a code for verification.
    • More secure than conventional passwords

    1.4.4 Internet Security for Real Life Situations

    • Online banking should always use encrypted connection protocols (SSL/TLS) to prevent data transmission interception.
    • Use strong passwords and regularly update security software (anti-virus, firewall, anti-spyware).
    • Be aware of phishing scams and never provide personal or financial details unless you are sure about email authenticity.
    • Avoid using public computers for sensitive transactions.

    Online Shopping

    • Verify website authenticity (ensure address starts with "https:", check for secure symbols).
    • Look for trusted third-party security certifications.
    • Use a credit card or payment service (not your regular credit card numbers).
    • Avoid public computers.

    Phishing

    • Phishing involves sending deceptive emails or messages to trick people into providing personal information to fraudsters.
    • Be vigilant about suspicious emails or texts.
