Study Notes
Vulnerabilities and Exploits
- A dangling vulnerability is a weakness in a system that is not currently exploitable.
- A dangling threat is a potential danger that cannot cause harm because there is no vulnerability to exploit.
Attack Types
- An attack is an attempt to gain access, cause damage, or compromise information and/or systems.
- Passive attack: the attacker observes interaction with the system without directly interacting with it.
- Active attack: the attacker directly interacts with the system.
- Unintentional attack: an attack without a deliberate goal of misuse.
Attack Surface
- The attack surface of an organization/entity is the set of ways an adversary can enter the system and potentially cause damage.
- Examples of attack surface include user input fields, protocols, interfaces, and services.
- Reducing the attack surface can be achieved by minimizing user input fields, limiting protocols and interfaces, and implementing secure coding practices.
Attacker and Defender Operations
- Attacker's operations include physical attack and destruction, electromagnetic attack, visual spying, intrusion, scavenging and removal, wiretapping, interference, and eavesdropping.
- Defender's operations include physical security, OPSEC, TEMPEST, encryption and key management, intrusion detection, anti-virus software, auditing, redundancy, firewalls, policies, and standards.
IA Levels
Infrastructure Level
- Focuses on the information structure level, including data structures, processes, and programs, protocols, data content, and databases.
- Desired effects include influencing the effectiveness and performance of information functions supporting perception, decision making, and control of physical processes.
- Attacker's operations include impersonation, piggybacking, spoofing, network attacks, malware, authorization attacks, active misuse, and denial of service attacks.
- Defender's operations include information security technical measures.
Perceptual Level (Social Engineering)
- Focuses on the perceptual level, concerned with managing perceptions of the target, particularly those making security decisions.
- Desired effects include influencing decisions and behaviors.
- Examples include interruption (denial of service attack), interception (compromise of confidential data), modification (hacking to deface a website), and fabrication (spoofing attacks in a network).
Environments and Enclaves
- Hostile environment: an environment with known threats, e.g., locating an asset in a war zone or a flood zone, or placing an unprotected machine on the Internet.
- Benign environment: a non-hostile environment protected from external hostile elements by physical, personnel, and procedural countermeasures.
- Enclave: a collection of computing environments connected by one or more internal networks under the control of a single authority and security policy, including personnel and physical security.
- Example of a local enclave: a university campus network.
