    Study Notes

    IT Security Management and Risk Assessment

    • IT security management involves answering questions like: what assets need protecting, how are those assets threatened, and what actions can be taken to counter those threats?
    • IT security management formally defines objectives and risk profiles for organizations' IT assets.
    • Confidentiality, integrity, availability, accountability, authenticity, and reliability of computer systems are key aims.
    • IT security risk assessments are needed for each asset requiring protection, answering: what assets need protection, what threats exist, and what countermeasures can be taken.

    Security Risk Analysis

    • Security risk analysis is the process of identifying, assessing, and mitigating risks to organizational assets, information, and operations.
    • Multiple approaches (baseline, informal, formal, combined) to security risk analysis exist for different needs and circumstances.
    • Baseline risk analysis compares current procedures to standards like ISO 27001 or NIST. It's a checklist approach.
    • Informal risk analysis uses observations, brainstorming, and expert opinions for quick identification in situations with inadequate data or time constraints.
    • Formal risk analysis applies defined techniques for in-depth and documented risk evaluations, frequently utilizing tools like FAIR or OCTAVE.
    • Combined risk analysis integrates different methods to achieve a balance between depth and practicality.

    Physical Security Control Types

    • Physical security controls protect physical assets (buildings, hardware, data centers) from unauthorized access, damage, or theft.
    • Three main types of physical controls are deterrent, preventive, and detective.
    • Deterrent controls like fences and warning signs create a barrier.
    • Preventive controls like locks and security guards limit access.
    • Detective controls like alarms and surveillance cameras identify and report intrusions.

    Security Policy

    • Security policy defines principles, guidelines, and requirements for maintaining security standards in an organization.
    • Policies can be informal descriptions of desired behavior or formal statements of rules and procedures.
    • When developing a security policy, factors like asset value, system vulnerabilities, and likely threats need consideration.

    Malicious Software (Malware)

    • Malware is a program designed to compromise the confidentiality, integrity, or availability of a system’s data.
    • Common malware types include Trojans (disguised malicious software), worms (self-replicating), and viruses (replicating by infecting files).

    Network Attacks

    • Network attacks attempt to compromise network security.
    • Two main attack types are passive and active. Passive attacks involve gathering information without disrupting services.
    • Active attacks involve disrupting services.
    • Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks overwhelm systems, preventing legitimate access.

    Encryption

    • Encryption is the process of converting plain text to an unreadable format (ciphertext).
    • Encryption aims to ensure confidentiality, protect data from unauthorized access, and secure communication between parties.
    • Different types of encryption exist (symmetric, asymmetric, hashing).

    Intrusion with or without Data Breaches

    • Intrusion is unauthorized entry into a system, while a data breach compromises data access and theft.
    • A potential intrusion could be a security investigation to explore vulnerabilities.
    • Implications of data breaches include legal liabilities.
    • Detection and response to intrusions involve identification of unauthorized access attempts, halting data exfiltration, and determining the extent of data exposure.
    • Intrusions without data breaches involve vulnerability discovery and exploitation.
    • Intrusions with data breaches involve unauthorized access and theft of sensitive data.

    Buffer Overflows

    • Buffer overflows are vulnerabilities that allow an attacker to insert more data into a buffer than it can hold.
    • This excess data can corrupt data and gain control of the system.
    • Buffer overflow attacks can be used to manipulate system behavior or corrupt data, leading to system crashes, unexpected actions, or even complete takeover.

    Firewalls

    • Firewalls act as a security barrier between internal networks and external networks.
    • Firewalls are central points regulating all inbound and outbound network traffic.
    • Firewalls ensure secure communication.
    • Firewalls check network traffic for security and compliance with rules.
    • Firewalls help protect internal networks by controlling and monitoring traffic.

    Access Control

    • Access control mechanisms regulate access to computer resources in a secure way.
    • Access control involves authentication and authorization processes for users.
    • Systems verify users’ identity (authentication) and define access rights (authorization).
    • This involves systems using various security features like passwords, biometrics, and security protocols to check and verify user identity.
    • Discretionary access control (DAC), mandatory access control (MAC), and role-based access control (RBAC) are different approaches to access control.
