Study Notes

Vulnerability Awareness

Many vulnerabilities impact both on-premises and cloud environments.
Cybersecurity professionals should prioritize understanding these vulnerabilities.
Weak patch management is a significant source of system vulnerabilities.

Vulnerability Types

False Positive: A vulnerability scan mistakenly identifies a vulnerability that does not exist.
False Negative: A scan fails to detect an actual vulnerability present in the system.

Threat Hunting

Activity aimed at discovering existing compromises within an organization.
Assumes that the network has already been breached.
Utilizes advisories, bulletins, and threat intelligence for investigative purposes.

Vulnerability Scanning

Probes systems for known security issues through network, application, and web testing.
Can be conducted in credentialed (with login) or noncredentialed (without login) contexts.
Scanning methods can be intrusive (actively test) or nonintrusive (passively observe).

Vulnerability Classification

Vulnerability scanning systems detect thousands of potential vulnerabilities.
Familiarity with common vulnerabilities is essential for cybersecurity analysts.

Patch Management

Critical to apply security patches to systems regularly.
Neglected patch management can lead to outdated software exposing systems to attacks.

Cybersecurity Responsibilities

Professionals must implement and maintain security controls against threats such as hackers and malware.
Regular security assessment and testing are essential to safeguarding the environment.

Vulnerability Management Programs

Essential for identifying, prioritizing, and remediating vulnerabilities in technical environments.
Should be a core component of any cybersecurity strategy.

Insecure Protocols

Older network protocols often lack security features, making them vulnerable to eavesdropping.
Telnet and FTP are examples of insecure protocols with no encryption.
Secure alternatives: SSH for command-line access and SFTP/FTPS for file transfers.

Weak Encryption

Proper configuration is critical for effective encryption.
The choice of encryption algorithm and key significantly affects security granted to stored and transmitted data.
Running unsupported operating systems presents security challenges, including lack of vendor support.

Best Practices for Unsupported Systems

If continuing to use unsupported OS, isolate from networks and implement compensating security measures.

Weak Configurations

Common issues include:
- Use of default settings that present security risks.
- Presence of unsecured accounts or default credentials.

Summary of Vulnerability Response Practices

Good practices include patching, segmentation, compensating controls, and cautious handling of exceptions.
