Basic Troubleshooting of Domain PC

  • Logging into a computer is a routine task
  • PC logon failures can be caused by various reasons
  • System Clock: A workstation's clock can cause a logon failure if the clock is more than five minutes different from the domain controllers' time.
  • The workstation sends a request to the Key Distribution Server with user ID, service requested, and an encrypted authenticator (using the user's master key)
  • When the server receives the request, it validates the time stamp
  • If the time difference is more than five minutes, the login fails.
  • DNS server failure can prevent logon access if domain controllers are functional.

Cyber Security

  • Computer security (cyber security) protects information systems from theft, damage, disruption, or misdirection.
  • It includes controlling physical access, network access, data and code injection, and malpractice by operators.
  • It is important due to increased reliance on computers and smart devices (like smartphones, internet and wireless networks like Bluetooth and Wi-Fi)
  • Information needs to be timely, accurate and complete.

Cyber Threat

  • Cyber threats are actions by persons attempting unauthorized access to control systems or networks using data communications.
  • Sources include hostile governments, terrorists groups, disgruntled employees, and malicious intruders.
  • Cyberspace is a conceptual electronic space, not bounded by physical geography
  • Attack methodologies include hacking, cyber crime, and cyber espionage.

Defensive Cyber Security

  • Physical security of IT assets is still under threat.
  • Measures include access controls, physical security of server rooms, environmental control (e.g., ensuring proper fire and emergency power systems).
  • Implementing access controls (e.g., ID cards, biometric access control, CCTV.)
  • Auditing access rights and permissions on a regular basis.
  • Personnel have a duty to be compliant with policies and procedures.

Vayusenix

  • A customized Linux-based operating system developed by the IAF.
  • Released in October 2009 and subsequently updated (e.g., 2.0, 3.0, 4.0, 4.1)
  • Designed to handle cyber attacks relating to client access to computers.
  • Built on Ubuntu
  • Includes security features of Linux (e.g., SELINUX)

Appendix

  • Multiple case studies are described concerning security incidents
  • Includes details about security breaches through social media, mobile phone use and other means.
  • Security policy, practices, procedures, and technology are highlighted.

Amendment Record

  • There is a section to record any amendments to the document.
