"Risk assessment" video:

 Risk Assessment Process: It's about identifying and prioritizing


risks based on their likelihood and impact to allocate resources
effectively.
 Definitions:

 Threat: An external force that jeopardizes security (e.g.,


hackers, natural disasters).
 Vulnerability: Weaknesses in security controls that threats
can exploit (e.g., missing patches).
 Risk: Occurs when both a threat and a vulnerability are
present.

 Risk Evaluation: Risks are ranked by their likelihood of occurrence


and potential impact, using either qualitative (subjective) or
quantitative (numeric) techniques.

This process helps cybersecurity professionals manage and mitigate risks


efficiently.
"Quantitative risk assessment" video:

 Quantitative Risk Management: Uses numeric data to make


informed decisions about risks.
 Key Variables:

 Asset Value (AV): The estimated dollar value of an asset.


 Exposure Factor (EF): The percentage of an asset that will
be damaged if a risk materializes.
 Single Loss Expectancy (SLE): Calculated by multiplying AV
by EF.
 Annualized Rate of Occurrence (ARO): The expected
number of times a risk will occur each year.
 Annualized Loss Expectancy (ALE): Calculated by
multiplying SLE by ARO.

 Time Values for IT Components:

 Mean Time to Failure (MTTF): Expected time before a non-


repairable asset fails.
 Mean Time Between Failures (MTBF): Average time
between failures for a repairable asset.
 Mean Time to Repair (MTTR): Time required to repair an
asset each time it fails.
These concepts and formulas are essential for performing a quantitative
risk analysis.
"Information classification" video:

 Purpose of Information Classification: Helps users understand


security requirements for handling different types of data.
 Classification Levels: Organizations classify data into categories
like high, medium, and low sensitivity, and differentiate between
public and private information.
 Handling Sensitive Information: Emphasizes the importance of
safeguarding personally identifiable information (PII), financial
information, and health records, using strong encryption and secure
disposal procedures.

These points highlight how organizations can effectively manage and


protect their sensitive information.
"Risk treatment options" video:

 Four Basic Risk Treatment Options:

 Risk Avoidance: Changing business practices to eliminate


the risk.
 Risk Transference: Shifting the impact of the risk to another
organization, often through insurance.
 Risk Mitigation: Reducing the likelihood or impact of the risk
through various controls.
 Risk Acceptance: Accepting the risk when other options are
too costly or impractical.

 Risk Concepts:

 Inherent Risk: The initial level of risk before any controls are
applied.
 Residual Risk: The remaining risk after controls are
implemented.
 Control Risk: New risks introduced by the implementation of
controls.

These strategies help organizations manage risks effectively within their


risk appetite.
"Security control selection and implementation" video:
 Types of Security Controls:

 Preventive Controls: Aim to stop security issues before they


occur (e.g., firewalls).
 Detective Controls: Identify potential security breaches
(e.g., intrusion detection systems).
 Corrective Controls: Remediate issues that have already
occurred (e.g., restoring data from backups).

 Control Categories:

 Technical Controls: Implemented through technology (e.g.,


encryption, antivirus software).
 Operational Controls: Processes managed by individuals
(e.g., user access reviews, log monitoring).
 Management Controls: Focus on risk management
processes (e.g., regular risk assessments, security planning).

 Defense in Depth Principle: Using multiple, overlapping controls


to ensure security even if one control fails.

These points cover the main aspects of selecting and implementing


security controls to manage risks effectively.
"Ongoing risk management" video, here are the key takeaways:

 Continuous Monitoring and Assessment: Security controls need


regular monitoring and assessment to ensure they remain effective.
This includes both self-assessments and external assessments.
 Effectiveness Measurement: Organizations should routinely
measure the effectiveness of their security controls, such as
tracking compromised accounts or vulnerabilities in systems.
 Continuous Improvement: A spirit of continuous improvement is
essential, using the results from control effectiveness measures and
risk assessments to enhance security over time.

These points highlight the importance of ongoing activities to manage


risks effectively.
"Risk management frameworks" video, here are the key takeaways:

 NIST Framework: The National Institute of Standards and


Technology (NIST) developed a widely used risk management
framework, detailed in Special Publication 800-37.
 Six Steps: The framework includes six steps: categorizing the
information system, selecting security controls, implementing
controls, assessing controls, authorizing system operation, and
ongoing monitoring.
 Preparation and Inputs: Before starting, gather information on
technology architecture and organization-specific details like laws,
regulations, and strategies.

These points provide a structured approach to managing risk using a


proven framework.

"Risk visibility and reporting" video:

 Risk Registers: These are centralized documents that track the


nature and status of each risk facing the organization, including
descriptions, categorizations, risk assessments, and mitigation
actions.
 Threat Intelligence: Sharing threat intelligence helps
organizations maintain visibility into risks and combat external
threats more effectively.
 Communication Tools: Risk Matrices or Heat Maps are used to
summarize risks for senior leaders, helping them focus on the most
significant risks.

These points emphasize the importance of documenting, tracking, and


communicating risks within an organization.
Malware:
"Comparing viruses, worms, and Trojans" video:

 Viruses: Spread through user actions like opening email


attachments or clicking on malicious links. They require user
intervention to propagate.
 Worms: Spread autonomously by exploiting system vulnerabilities
without user interaction. They can infect systems and spread across
networks independently.
 Trojans: Disguise themselves as legitimate software but carry
hidden malicious payloads. They rely on users to install them,
thinking they are harmless applications.

These points highlight the different propagation mechanisms and


characteristics of each type of malware.
"Malware payloads" video:

 Adware: Displays advertisements to generate revenue for the


malware author, often by redirecting search queries or displaying
pop-up ads.
 Spyware: Gathers information without the user's consent, which
can be used for identity theft or espionage.
 Ransomware: Blocks access to data or systems until a ransom is
paid, commonly by encrypting files and demanding payment for the
decryption key.
 Cryptomalware: Uses the infected system's computing power to
mine cryptocurrency, generating revenue for the malware author.

These types of malware payloads all undermine system security and


require proactive measures like antivirus software, security patches, and
user education to prevent infections.

"Understanding backdoors and logic bombs":

 Backdoors: These are pieces of code inserted into applications to


provide future access to a system, often for convenience or support
purposes. However, they can pose significant security risks if
discovered and misused by unauthorized individuals.
 Logic Bombs: This type of malware is designed to execute a
malicious action when specific conditions are met, such as a
particular date or the absence of a programmer from the payroll.
 Security Implications: Both backdoors and logic bombs represent
serious threats to application security. It's crucial to routinely
change default passwords, disable unused accounts, and monitor
security bulletins to protect against these threats.

Feel free to ask if you need more details on any of these points!
"Botnets":

 Botnets: These are networks of infected computers (zombie


computers) controlled by hackers for malicious purposes.
 Uses of Botnets: Botnets are often rented out to deliver spam,
conduct distributed denial of service (DDoS) attacks, mine
cryptocurrency, or perform brute force attacks on passwords.
 Command and Control: Hackers use indirect command and
control mechanisms, such as IRC channels, Twitter accounts, and
peer-to-peer communication, to manage botnets and avoid
detection.

Feel free to ask if you need more details on any of these points!
"Advanced persistent threats":

Zero-Day Vulnerabilities: These are unknown vulnerabilities that


can be exploited by attackers before a patch is available, making
them highly dangerous.
 Advanced Persistent Threats (APTs): These attackers are well-
funded and highly skilled, often associated with military units or
government agencies. They use sophisticated methods, including
zero-day vulnerabilities, to target specific organizations.
 Defense Strategies: Implementing strong security measures, such
as encryption and rigorous monitoring, can help protect against
APTs, although complete defense is challenging due to their
advanced capabilities.
"Cybersecurity adversaries":

 Types of Attackers: Attackers can be internal or external, ranging


from unskilled individuals (script kiddies) to highly sophisticated
groups (nation-states and APTs).
 Motivations: Attackers' motivations vary, including thrill-seeking
(script kiddies), political or social agendas (hacktivists), financial
gain (organized crime), corporate espionage, and national interests
(nation-states).
 Sophistication Levels: Attackers' skills and resources differ
significantly, from basic (script kiddies) to advanced (nation-states
and APTs), impacting the complexity of the threats they pose.

"Preventing insider threats":

 Insider Threats: These are risks posed by current or former


employees, contractors, and other insiders who may exploit their
access to systems to steal information, money, or cause damage.
 Statistics: Over half of organizations that experienced a security
breach were victims of insider attacks, and these breaches are often
more costly to remediate than external attacks.
 Preventive Measures:

 Perform background checks on potential employees.


 Follow the principle of least privilege, giving users only the
permissions necessary for their job.
 Implement two-person control for sensitive transactions.
 Enforce mandatory vacation policies to uncover fraudulent
activities.

 Be vigilant about shadow IT, which can introduce risks without


the knowledge of technology leaders.

"DNS attacks" video:

 DNS Poisoning: This involves introducing false DNS records to


redirect traffic to an attacker's system, potentially capturing login
credentials and other sensitive information.
 Typosquatting: Attackers register domain names that are common
typos of legitimate sites to redirect users to malicious sites.
 Domain Hijacking: Attackers take over a domain registration
without the owner's permission, often using social engineering or
stolen credentials.
 URL Redirection: Malicious content on a legitimate site redirects
users to a harmful site.
 Domain Reputation Systems: These help identify whether traffic
is coming from trusted or malicious domains, aiding in cybersecurity
efforts.

"Layer 2 attacks" video:

 ARP Poisoning: This spoofing technique provides false information


in response to ARP requests, causing a victim system to send traffic
to a malicious user's system, enabling man-in-the-middle attacks.
 MAC Flooding: Attackers overwhelm a network switch's MAC
address table, causing it to broadcast traffic to all ports, which
allows eavesdroppers to view normally inaccessible traffic.
 Port Security: Implementing port security can limit the number of
MAC addresses on a single switch port, helping to block MAC
flooding attacks.

"Network address spoofing" video:

 Network addresses can be altered: Both IP and MAC addresses


can be changed by anyone with administrative access, making them
unreliable for authentication.
 MAC spoofing: Attackers can change the MAC address of a system
using normal operating system commands, a process known as MAC
cloning.
 IP spoofing: Similar to MAC spoofing, IP addresses can also be
altered, but are often used in denial of service attacks rather than
two-way communication.
 Anti-spoofing controls: Technologies like ingress and egress
filtering can help prevent spoofing attacks by monitoring incoming
and outgoing traffic for signs of spoofing.
"Network address spoofing" video:

 Network addresses can be altered: Both IP and MAC addresses


can be changed by anyone with administrative access, making them
unreliable for authentication.
 MAC spoofing: Attackers can change the MAC address using
normal operating system commands, a process called MAC cloning,
to assume another system's identity or participate in attacks.
 IP spoofing: Similar to MAC spoofing, IP addresses can also be
altered. However, they are often used in denial of service attacks as
they are difficult to use for two-way communication.
 Anti-spoofing technologies: These can be implemented at the
router, firewall, or switch to prevent spoofing attacks. Ingress and
egress filtering are examples of such controls.
This video provides a detailed explanation of how these spoofing
techniques work and the measures to prevent them.

"Password attacks" video:

several drawbacks, making them susceptible to various attacks.
 Types of Password Attacks: The video covers four common types
of password attacks:

 Brute Force Attack: Guessing all possible password


combinations.
 Dictionary Attack: Trying all words in the dictionary.
 Hybrid Attack: Combining dictionary words with common
variations.
 Rainbow Table Attack: Using pre-computed password
hashes to speed up the attack.

 Hashing and Security: Passwords are hashed using a one-way


function to enhance security, but attackers can still perform offline
brute force attacks if they obtain the password file.
"Password spraying and credential stuffing":

 Password Spraying: Attackers use a list of commonly used


passwords to attempt to access many different accounts
simultaneously. The best defense is to prevent users from selecting
commonly used passwords.
 Credential Stuffing: Attackers use stolen username and password
combinations from one site to try and access accounts on other
sites. The best defense is to avoid reusing passwords across
multiple sites and to use password management tools.
 Multifactor Authentication: Adding an additional authentication
factor beyond the password is an effective defense against both
types of attacks, as it stops the attacks halfway through the
authentication process.

 Importance of Strong Hashing and Multifactor


Authentication: Ensuring strong hashing algorithms and using
multifactor authentication can significantly improve password
security.

"Watering hole attacks":

 Concept: Watering hole attacks involve compromising commonly


visited websites to spread malware to unsuspecting users.
 Mechanism: Attackers identify and compromise a targeted
website, exploit vulnerabilities in the visitors' browsers, and install
malware.
 Defense: Both website owners and users must stay current on
security patches to prevent falling victim to these attacks.

"Social engineering":

 Psychological Tricks: Social engineering attacks manipulate


people into divulging sensitive information or performing actions
that compromise security using tactics like authority, intimidation,
consensus, scarcity, urgency, and familiarity.
 Examples: Attackers may pose as help desk technicians to obtain
passwords or use intimidation to force compliance.
 Defense: The best defense is user education. Everyone in the
organization should be aware of these tactics and remain vigilant
against them.

"Impersonation attacks":

 Spam and Phishing: Spam, including phishing, is used to trick


users into revealing sensitive information like passwords. Phishing
messages often appear legitimate to deceive users.
 Spear Phishing and Whaling: These are targeted phishing
attacks aimed at specific individuals or high-level executives, using
personalized information to increase success rates.
 Other Forms: Impersonation attacks can also include vishing (voice
phishing), smishing (SMS phishing), and spoofing, where attackers
fake the identity of someone else to gain trust and information.

Education and awareness are crucial to defend against these types of


social engineering attacks.

"Physical social engineering":

 Shoulder Surfing: Attackers look over the victim's shoulder to


gather sensitive information. Solutions include being aware of
surroundings and using privacy filters on screens.
 Dumpster Diving: Attackers search through trash for sensitive
documents. The best defense is to shred all documents before
disposal.
 Tailgating: Attackers follow authorized personnel into secure areas
without proper credentials. Education and awareness, along with
posted reminders, are effective defenses.

and MSAs, each serving different purposes in vendor relationships.
 Service Level Requirements (SLRs): Establishes expectations for
the vendor's service quality, which are then documented in SLAs.
 Security and Compliance: Agreements should include provisions
for security and compliance, allowing for audits and assessments to
ensure standards are met.

These points highlight the importance of clear, well-documented


agreements in managing vendor relationships effectively.

"Vendor agreements":

 Types of Agreements: Includes NDAs, SLAs, MOUs, BPAs, ISAs,


and MSAs, each serving different purposes in vendor relationships.
 Service Level Requirements (SLRs): Establishes expectations for
the vendor's service quality, which are then documented in SLAs.
 Security and Compliance: Agreements should include provisions
for security and compliance, allowing for audits and assessments to
ensure standards are met.
These points highlight the importance of clear, well-documented
agreements in managing vendor relationships effectively.

"Legal and compliance risks":

 Jurisdictional Complexity: Determining which laws and


regulations apply to sensitive data can be complex, especially when
operations span multiple states or countries.
 GDPR and Other Regulations: The GDPR applies to personal
information of EU residents globally, and there are various other
national, territorial, and state laws to consider.
 Self-Regulatory Schemes: Some regulations, like the PCI DSS for
credit card transactions, are enforced by industry bodies rather than
government authorities.

These points highlight the importance of understanding and navigating


the various legal and compliance risks associated with handling sensitive
information.

"Privacy compliance":

 Privacy Laws: Various laws protect individual privacy and prevent


identity theft and unauthorized disclosure of personal information.
Examples include HIPAA, FERPA, GLBA, COPPA, and the Privacy Act
of 1974 in the U.S.
 International Regulations: The GDPR in the European Union and
PIPEDA in Canada are broad regulations covering many types of
personal information. APEC's Cross-Border Privacy Enforcement
Arrangement governs privacy across Asia-Pacific countries.
 Compliance Requirements: Organizations must comply with
relevant laws based on their industry, location, and the nature of the
data they handle, ensuring robust privacy and security measures.

"Intellectual property":

 Types of Intellectual Property: Includes copyrights, trademarks,


patents, and trade secrets, each protecting different types of
information.
 Copyrights: Automatically granted to creators, protecting creative
works like books, music, and software. They last for a long time,
often 70 years beyond the creator's death.
 Trademarks: Protect brand names, logos, and slogans. They must
be registered and can last indefinitely with renewal every 10 years.
 Patents: Protect inventions, providing exclusive use for about 20
years. They require public disclosure of the invention.
 Trade Secrets: Protect information by keeping it secret. If
someone else discovers the secret independently, they can use it.

"Audits and assessments":

 Purpose and Function: Both audits and assessments evaluate


security controls, but audits are typically requested by external
parties like regulators, while assessments are initiated by an
organization's IT staff.
 Planning and Scope: Effective audits and assessments start with
clear planning, defining the scope, timeline, and deliverables to
avoid misunderstandings.
 Types of Auditors: Internal auditors are part of the organization
but report independently, while external auditors are independent
firms providing unbiased assessments.

These points highlight the importance of thorough planning and clear


distinctions between audits and assessments.

These strategies and types help ensure that data can be restored
efficiently and effectively in case of a disaster.

"Cloud audits":

 Scope of Cloud Audits: Cloud audits involve evaluating the


security controls of both the organization and its cloud service
providers.
 SOC Reports: Cloud service providers conduct their own audits and
provide Service Organization Control (SOC) reports to customers,
which come in three types (SOC 1, SOC 2, SOC 3) and two report
types (Type 1 and Type 2).
 Audit Standards: SOC audits follow standards like SSAE 18 in the
U.S. and ISAE 3402 internationally, ensuring consistency and
reliability in the audit process.

These points highlight the unique challenges and solutions in auditing


cloud environments.
