Of the CompTIA CySA+ books I've read, I learned the most from this one.
Notes
Utilizing Threat Intelligence to Support Organizational Security
Threat actor ranking criteria
• Skill level: None, minimal, operational, adept
• Resources: Individual, team, organization, government
• Limits: Code of conduct, legal, extra-legal (minor, major)
• Visibility: Overt, covert, clandestine, don’t care
• Objective: Copy, destroy, injure, take, don’t care
• Outcome: Acquisition/theft, business advantage, damage, embarrassment, technical advantage
Threats and Vulnerabilities Associated with Operating in the Cloud
Key stretching (aka key strengthening): cryptographic technique that makes weak key stronger by increasing time required to test each possible key. Algorithms: PBKDF2, bcrypt, scrypt.
Implementing Controls to Mitigate Attacks and Software Vulnerabilities
Prevent directory traversal by filtering user’s input and removing metacharacters.
Reflected XSS attack (aka non-persistent or Type II attack): web app immediately returns user input in error message or search result without data being made safe to render in browser, and without permanently storing user-provided data.
Persistent XSS attack (aka stored or Type I attack): stores user input on target server (in DB, forum, visitor log, comment field, etc.). Victim is able to retrieve stored data from web app without data being made safe to render in browser.
DOM XSS attack (aka Type 0 attack): takes place entirely in browser.
Security Solutions for Infrastructure Management
Bastion host: device that's exposed directly to Internet or any untrusted network while screening rest of network from exposure (e.g., firewalls, FTP servers, DNS servers, web servers, email servers).
3 planes
• Control plane: Carries traffic between routers. Allows routers to share info and build routing tables.
• Data plane (aka forwarding plane): Carries user traffic.
• Management plane: Administers router.
SAML provides SSO using web browser.
OpenID is less complex than SAML.
Hardware Assurance Best Practices
Virtual TPM (vTPM): software object that performs functions of TPM chip. Enables trusted computing for unlimited number of VMs on single hardware platform.
Analyzing Data as Part of Security Monitoring Activities
Packet analysis examines entire packet, including payload. Protocol analysis is subset of packet analysis, and examines only packet header, not payload.
Agentless SIEM collection has advantage of not needing to install agents, but disadvantage of lacking filtering and aggregation at host level, causing larger amounts of data to be transferred to SIEM, and increasing time needed to filter and analyze logs. Another potential disadvantage is SIEM server may need credentials to authenticate to each host.
Analyzing Potential Indicators of Compromise
Network-related IoCs
• Bandwidth consumption
• Beaconing
• Irregular P2P communication
• Rogue device on network
• Scan/sweep occurring
• Unusual traffic spike
• Common protocol over non-standard port
Host-related IoCs
• Processor consumption
• Memory consumption
• Drive capacity consumption
• Unauthorized software
• Malicious process
• Unauthorized change
• Unauthorized privilege
• Data exfiltration
• Abnormal OS process behavior
• File system change or anomaly
• Registry change or anomaly
• Unauthorized scheduled task
Application-related IoCs
• Anomalous activity
• Introduction of new accounts
• Unexpected output
• Unexpected outbound communication
• Service interruption
• Application log errors or warnings
Wireless intrusion prevention system (WIPS) alerts when unknown AP or station is in area. Can also locate rogue APs, deauthenticate stations that have connected to “evil twin,” detect DoS, detect MITM and client-impersonation attacks.
