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.
