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.
