External Network Pentests

Review methodologies for External Networks.

Overview of test methodologies for external networks. Includes instances of Microsoft Office 365.

We use the penetration testing methodologies listed on the page. If you want to know more about each methodology, navigate to the page associated with your asset.

External Networks

The Cobalt team of pentesters can proceed with a minimum of information, such as the IP addresses in question. However, you can include the following details in the scope of your desired pentest:

  • Network diagrams
  • Infrastructure diagrams
  • Accounts (even temporary accounts for pentests)
  • User information

When you set up a pentest for an external network asset in the UI, you’ll see the following in the Objectives text box:

Coverage of OSSTMM and SANS top 20 security controls.

Learn more about these objectives:

We follow an industry standard methodology primarily based on the OSSTMM standard for penetration testing.

  • Reconnaissance
    • Corporate website
    • Related websites, databases
    • DNS
    • Public records (such as WHOIS information)
  • Service discovery
    • Port scans on specific IP ranges
    • Focus on public-facing services
    • Follow-up with further tests
  • Vulnerability scans
    • Test for penetration of the internal network
  • Manual assessment
    • Public-facing services (Web, FTP, Email, Firewalls, Routers, DNS, VPNs, and more)
  • Report, triage, and retest
    • Requires tests of at least two (2) credits

Additional Requirements

You’re welcome to define additional test objectives. If you follow best practices other than OWASP, ASVS, or OSSTMM, let us know. Include a link or other documentation. If it’s a “well-known” security practice, our pentesters probably already know them!

If you have special instructions for a pentest, add them later, under Special Instructions.
