Study Notes

Shadow IT and Cloud Security

Eliminating shadow IT in an enterprise requires reducing the risk of unauthorized cloud applications and services.
A Cloud Access Security Broker (CASB) is a tool that provides visibility and control over cloud applications and services.
CASB enables policy enforcement by:
- Blocking unauthorized or risky cloud applications
- Enforcing data loss prevention rules
- Encrypting sensitive data
- Detecting anomalous user behavior

Incident Response and DDoS Attacks

A Distributed Denial-of-Service (DDoS) attack is a type of cyberattack that aims to overwhelm a network or system.
In the event of a DDoS attack, the incident response team should review the following logs first:
- DNS logs (to identify the source of the attack and affected domains)
DNS logs are crucial in investigating DDoS attacks, as they can help identify the source of the attack and affected domains.

On-Path Attack

An on-path attack is being performed by someone with internal access that forces users into port 80.
This suggests a potential security threat that should be investigated further due to inconsistent access to the internal portal.

Vulnerability Management

The Company uses the CVSSv3.1 Base Score Metrics (Exploitability and Impact) to prioritize the remediation of security vulnerabilities.
When choosing between confidentiality and availability, the Company prioritizes confidentiality of data over availability of systems and data.
Patching of publicly available systems and services takes priority over patching of internally available systems.

Incident Response

Collecting malicious files is important to gather valuable information about the nature of the attack, malware used, and potentially the threat actor responsible.
This allows for analysis without altering the system's state.
Malicious files are prioritized over collecting a routing table in incident response due to their volatility and importance in investigating the incident.

Automation in Security Operations

DNS logs are ideal for automation in security operations, especially for identifying and mitigating DDoS attacks.
DNS logs provide detailed information on IP addresses of devices sending traffic to the target, helping to identify attackers.

Cyber Kill Chain

If a malicious actor has gained access to an internal network through social engineering and wants to maintain access, they are currently operating in the Command and Control stage of the Cyber Kill Chain.
