Study Notes
Social Engineering
- A caller pretended to be the CFO to trick a user into giving away credit card information
- The user recognized the attempt as a social engineering scam and reported it to the IT helpdesk
SIEM
- SIEM stands for Security Information and Event Management
- A SIEM system is a detective control used to monitor, collect, correlate, and analyze security data from multiple sources
- It detects and reports on potential security incidents, generating alerts for the security team
Supply Chain Vendor Risk
- A SaaS provider deploying a new system poses a risk due to the potential for the vendor to have poor security practices resulting in data breaches or compromises
- Implementing due diligence procedures and establishing a service level agreement with the vendor can mitigate the risk
Nation-State Threats
- Nation-states are a significant threat due to their vast resources, advanced technical skills, and motives including espionage, sabotage, and warfare
- They are often motivated to target essential systems such as military, energy, or infrastructure, often using malware or other techniques
Data Loss Prevention
- DLP stands for Data Loss Prevention
- DLP tools can help organizations detect and prevent unauthorized transmission or leakage of sensitive data, such as a customer's PII (Personally Identifiable Information)
- These tools monitor data in motion (emails), data at rest (files), and data in use (applications)
- DLP can alert senders, recipients, or administrators of data breaches and implement remediation actions like encryption, quarantine, or deletion
- DLP can help organizations comply with data protection regulations such as GDPR, HIPAA, or PCI DSS
Malware Detection
- A cyber operations team alerted a security analyst about a new malware tactic used by attackers to compromise networks
- In the absence of configured SIEM alerts, the analyst will need to investigate further to identify potential malware
Jump Server
- A jump server acts as an intermediary between a user and the target system, isolating the target system from the external network
- This isolation enhances security as access is granted only through the jump server
- Jump servers can enforce security policies for user connections, including authentication, authorization, logging, and auditing
- They are also known as bastion hosts or jump boxes
Data Loss Impact
- The data category most impacted by loss is "Critical"
- Critical data is essential for an organization's operations and includes financial records, proprietary business information, and vital operational data
- Its loss disrupts business operations and can have significant financial, legal, and reputational consequences
- Confidential data is protected from unauthorized access for privacy and security
- Public data is intended for general disclosure with minimal impact from loss
- Private data is personal information that needs to be protected for privacy
- Critical data is essential to an organization's operations and survival, its loss can be devastating
