# SECURITY ASSESMENTS

## Vulnerability Assesment
A vulnerability assessment can be based on various security standards. Which standards apply to a particular network will depend on many factors. These factors can include industry-specific and regional data security regulations, the size and form of a company's network, which types of applications they use or develop, and their security maturity level.

## Penetration Testing
Penetration tests are conducted to determine if and how a network can be penetrated.

### Pentest Specialties 
1. Application pentest
1. Network infrastructure pentest
1. Physical pentest
1. Social engineering pentest

### Security Maturity Level
Security maturity measures how well developed a company's cybersecurity program is.
Security maturity takes years to build

Organizations with a lower security maturity level may want to focus on vulnerability assessments because a pentest could find too many vulnerabilities to be useful and could overwhelm staff tasked with remediation. Before penetration testing is considered, there should be a track record of vulnerability assessments and actions taken in response to vulnerability assessments.

## Vulnerability Assesment vs Penetration Testing
#### Vulnerability assessments
looks for vulnerabilities in networks without simulating cyber attacks

All companies should perform vulnerability assessments every so often. A wide variety of security standards could be used for a vulnerability assessment, such as GDPR compliance or OWASP web application security standards. A vulnerability assessment goes through a checklist.

    Do we have this configuration?

During a vulnerability assessment, the assessor will typically run a vulnerability scan and then perform validation on critical, high, and medium-risk vulnerabilities. This means that they will show evidence that the vulnerability exists and is not a false positive, often using other tools, but will not seek to perform privilege escalation, lateral movement, post-exploitation, etc., if they validate, for example, a remote code execution vulnerability.

#### Penetration testing
A pentest is a simulated cyber attack to see if and how the network can be penetrated. 

Evaluate the security of different assets and the impact of the issues present in the environment. Penetration tests can include manual and automated tactics to assess an organization's security posture. They also often give a better idea of how secure a company's assets are from a testing perspective.

Regardless of a company's size, industry, or network design, pentests should only be performed after some vulnerability assessments have been conducted successfully and with fixes

### Othe Types of Security Assesments
Other types of security assesments may also be necessary depending on the type of the organization

## Security audits
Unlike vulnerability assesment which is an organizations own initiative to conduct them. a security audit is a requirement from outside the organization and they're typically mandated by government agencies or industry associations to assure that an organization is compliant with specific security regulations

For example, all online and offline retailers, restaurants, and service providers who accept major credit cards (Visa, MasterCard, AMEX, etc.) must comply with the PCI-DSS "Payment Card Industry Data Security Standard"

A company that accepts credit and debit card payments may be audited for PCI DSS compliance, and noncompliance could result in fines and not being allowed to accept those payment methods anymore.

Regardless of which regulations an organization may be audited for, it's their responsibility to perform vulnerability assessments to assure that they're compliant before they're subject to a surprise security audit.

## Bug bounty
Bug bounty programs are implemented by all kinds of organizations. They invite members of the general public, with some restrictions (usually no automated scanning), to find security vulnerabilities in their applications.

## Red team assesment
Companies with larger budgets and more resources can hire their own dedicated red teams or use the services of third-party consulting firms to perform red team assessments. A red team consists of offensive security professionals who have considerable experience with penetration testing. A red team plays a vital role in an organization's security posture.

These assessments typically have an end goal (i.e., reaching a critical server or database, etc.). The assessors only report the vulnerabilities that led to the completion of the goal, not as many vulnerabilities as possible as with a penetration test.

## Purple Team Assessment
A blue team consists of defensive security specialists. These are often people who work in a SOC (security operations center) or a CSIRT (computer security incident response team). Often, they have experience with digital forensics too. So if blue teams are defensive and red teams are offensive, red mixed with blue is purple.

What's a purple team?

Purple teams are formed when offensive and defensive security specialists work together with a common goal, to improve the security of their network. Red teams find security problems, and blue teams learn about those problems from their red teams and work to fix them. A purple team assessment is like a red team assessment, but the blue team is also involved at every step. The blue team may even play a role in designing campaigns. "We need to improve our PCI DSS compliance. So let's watch the red team pentest our point-of-sale systems and provide active input and feedback during their work."
