Study Notes
IPS Log Analysis
- A security log from an IPS shows an alert for Cross-Site Scripting in JSON Data on 2018-06-01 13:07:29.
- The log includes a User Agent string indicating the use of curl/7.21.3.
- The detail section shows a token with an empty value and a key "key7" with a value "alert(2)".
- From this log, it can be determined that the attacker's IP address is 222.43.112.74 and the target IP address is 64.235.145.35.
Risk Management and Security
- ALE (Annualized Loss Expectancy) is a monetary loss if one event occurs.
- SLE (Single Loss Expectancy) is the expected monetary loss of a single event.
- RTO (Recovery Time Objective) is a measure of the time taken to recover from an outage or incident.
SQL Injection
- A user with restricted access submitted a search query "USER77' OR '1'='1" which returned all database records.
- This is an example of SQL injection.
Authentication
- TOTP (Time-Based One-Time Password) is a type of authentication mechanism.
Cloud Security
- An open database instance in a cloud service is vulnerable to unauthorized access due to improper permissions.
Phishing
- An email offering a cash bonus for completing an internal training course is an example of phishing.
- The email requires users to login with their Windows Domain credentials on an external server.
Risk Management Strategies
- The purchase and installation of an NGFW (Next-Generation Firewall) is an example of a mitigation strategy.
Secure Baseline
- Comparing a production application to a secure baseline instance is the best way to confirm its security.
Separation of Duties
- A delay in an important financial transfer due to the absence of a team member could have been prevented by implementing separation of duties.
Log Analysis
- A log showing multiple sessions from a single IP address with a TTL equal to zero is indicative of a vulnerability scan.
Buffer Overflow
- An attacker sending more information than expected in a single API call, allowing the execution of arbitrary code, is an example of a buffer overflow attack.
