Study Notes
Cyber Security Strategy
- A cyber security strategy is a high-level plan to secure assets over three to five years.
- The plan should be updated sooner than three years as technology and cyber threats evolve quickly.
Cyber Security Controls
- Security controls are countermeasures that reduce the risk of threats exploiting vulnerabilities.
- Controls help with developing and implementing a cyber security strategy.
Top Security Threats
- Crypto ransomware is malware that restricts access to infected systems and demands payment for removal.
- Examples of ransomware tactics include encrypting personal files, locking system access, and overloading system resources.
Crypto Ransomware Families
- Many ransomware families have emerged over time, including notable ones like WannaCry, BadRabbit, LockDroid, KeRanger, and CryptoApp.
- The number of crypto-ransomware families has increased from 2005 to 2017.
Addressing Ransomware
- The decision to pay a ransom is complex and debated.
- Security controls can help prevent ransomware attacks, such as:
- Regularly backing up critical data
- Maintaining updated software and patches
- Implementing strong passwords
- Training users to identify and avoid phishing scams
Cyber Security Framework
- A cyber security framework is a system of standards, guidelines, and best practices for managing digital risks.
- Implementing security controls aligns with cyber security strategy objectives, like preventing unauthorized access.
Physical Security
- Physical security refers to the measures taken to protect physical assets and people from threats.
- It prioritizes life safety over facility safety in emergency situations.
Threats to Physical Security
- Physical security threats include:
- Natural disasters (earthquakes, floods, storms, fires)
- Utility system failures (communication and power outages)
- Human-made events (explosions, vandalism, theft, terrorist attacks, riots)
CPNI (Centre for the Protection of National Infrastructure)
- CPNI is a UK government authority that provides security advice to national infrastructure organizations.
- Their mission is to reduce vulnerability to terrorism and other threats.
- CPNI offers free advice to industry, including:
- General security advice
- Physical security guidelines
- Personnel security
- Cyber security
CBR (Chemical, Biological and Radiological Defence)
- CBR focuses on defense against chemical, biological, and radiological threats.
- It involves implementing measures like:
- Filter air conditioning systems
- Planning for quick shutdown of systems that spread airborne hazards
- Ensuring doors and windows can be closed quickly
- Having a well-defined plan for response
A Layered Defense Model
- A layered defense model involves multiple layers of physical security controls to protect assets:
- Perimeter security
- Building grounds security
- Building entrance security
- Building floors/office suites security
- Offices/data centers
- Equipment, supplies, and media security
Site Selection and SAPMA
- A detailed site selection process is crucial for physical security.
- SAPMA (Security Assessment for Protectively Marked Assets) evaluates security based on three key elements:
- Delay: Measures that slow down attackers (e.g., secure storage)
- Deter: Measures that discourage attackers (e.g., entry control)
- Detect: Measures that identify attacks (e.g., video surveillance)
Delaying Attacks
- Secure storage involves using containers and locks.
- Perimeter security includes fences and other barriers.
Deterrent Measures
- Entry control includes measures like visitor control and access oversight.
- Compliance checks, such as searches, can be a deterrent.
Controlled Access Points
- Gates and bollards provide controlled access points and deter vehicle intrusion.
Guards and Guard Stations
- Guards serve as deterrents but require motivation and attentiveness.
- Guard stations must offer visibility and access control.
Data Center Security
- Data center security includes:
- Constructing rooms with solid, fire-proof walls
- Implementing multi-factor access controls
- Posting access control lists
- Using CCTV for surveillance
