Here’s an elaboration on the topics you provided regarding Security Issues:

Security Issues

Physical Protection

• Environmental Damage Prevention: Organizations must protect their infrastructure from natural disasters, such as floods, earthquakes, and extreme temperatures. This can include:

  • Site Selection: Building in locations less prone to natural disasters.
  • Infrastructure Resilience: Using materials and designs that can withstand environmental stresses.

• Physical Security Measures: These measures include:

  • Locked Rooms and Equipment: Ensuring that sensitive areas and devices are secured against unauthorized access.
  • Cable Management: Securing keyboards, computers, and other devices to prevent theft or tampering.

• Electrical Protection: To mitigate risks from power surges:

  • Surge Protectors and Uninterruptible Power Supplies (UPS): Installing these devices can protect equipment from voltage spikes and provide backup power during outages.

• Noise Protection: This involves:

  • Strategic Placement: Locating computers away from devices that produce electromagnetic interference, like motors or microwaves, to reduce potential data corruption or hardware malfunction.

Surveillance

• Security Cameras: Proper placement of surveillance cameras can:

  • Deter Theft and Vandalism: The visible presence of cameras can discourage criminal behavior.
  • Provide Evidence: Recorded footage can be invaluable in investigating incidents.

• Intrusion Detection Systems: Specialists work to:

  • Prevent Unauthorized Access: Implementing measures to detect and respond to breaches in real time.
  • Analyze Breach Attempts: Understanding attack vectors to strengthen defenses.

• Honeypots: This technique involves:

  • Creating Decoy Systems: Network personnel design systems that mimic real assets, drawing in malicious actors to observe their tactics and motives.

Security Policy and Management

Attackers’ Advantage

• Asymmetry of Attack: It is typically easier for attackers to exploit vulnerabilities than for defenders to detect and respond to attacks, highlighting the need for robust security practices.

• Achieving Security: Complete security is unattainable, but:

  • User Responsibility: Users should engage in “safe computing” practices, such as:
    • Avoiding downloads from untrusted sources.
    • Not opening suspicious email attachments.
    • Being wary of fraudulent websites and scams.

• Luck vs. Diligence: Attackers may succeed due to chance, while defenders must rely on thoroughness, following established standards (like COBIT, ISO), and fostering a culture of security awareness and collaboration.

Security Policy Design Issues

• Defining Security Levels: Companies need to determine:
  • Their desired security posture and how much they are willing to invest in protective measures.
• Access Restrictions: It’s critical to evaluate:
  • Not just Internet access, but all potential entry points to the network and physical facilities.
• Policy Development: A comprehensive security policy is necessary to:
  • Balance risks against protective measures, ensuring all potential threats are considered.

Auditing

• Audit Creation: Regular audits (both digital and physical) can help:

  • Detect Malfeasance: Identifying unauthorized actions and correcting vulnerabilities.

• Deterrence: Knowing that audits occur can discourage potential wrongdoers from attempting breaches.

• Transaction Auditing: Many network operating systems provide tools for:

  • Monitoring Activity: Enabling administrators to track and review transactions and changes made within the system.

• Criminal Accountability: Numerous cases have shown that thorough auditing can lead to:

  • The apprehension of individuals involved in cybercrime.
