Vulnerability Assessments

View summary PDF


Business Issue:

If your organization depends on the Internet and Modern Technologies to conduct business, you have to stay one step ahead of emerging hackers, viruses and threats. If you do not, your business will be disrupted and that could be very costly. It makes good business sense to frequently test then patch your Internet, I/T Technologies and Communications services for vulnerabilities and risks.

Types of Assessments:

  1. PCI-Compliant (MasterCard Compliant) External Vulnerability Assessment simulates a "hacker" trying to penetrate your firewall and DMZ.

  2. Internal Vulnerability Assessment simulates a "disgruntled employee" and attempts to exploit vulnerabilities inside your firewall and on your LAN.

  3. CIS (Center for Internet Security) Benchmarks provide a score from 0-100, grading your servers and databases for security competence against "best industry practices". www.cisecurity.org

  4. Social Engineering attempts to gain access and vital knowledge by communicating with employees and business partners.

  5. Wireless Vulnerability Assessment uses "drive-by and walk-by" attempts to gain access to private wireless networks and assets, using modern technology.

  6. Database and Web Application Assessment to determine security protections at these levels of the business.

Risk Assessment

Any vulnerability is categorized in one of the following five (5) severity levels:
  • Urgent and Critical (security holes)

  • High and Medium (security warnings)

  • Low (security info)

A scanned device is considered 100% secure if no vulnerabilities are found at all. The following scale defines how much needs to be subtracted from that 100% for a given range of vulnerabilities:

"Critical/Urgent" "High/Medium warnings" "Low (security info)"
Range Score Range Score Range Score
1 20% 1 - 2 10% 2 - 3 5%
    3 - 5 30% 4 - 7 20%
2 - 3 50% 6 - 8 50% 7 - 12 50%
> 3 100% > 8 100% > 12 100%


To further classify the risk for a given device (or even a complete organization), xDefenders uses this scale:

Score Risk
100% None
> 80% Low
> 70% Medium
<= 70% High



Description:

For External and Internal Vulnerability Assessments, xDefenders offers SysDefender, a hardened Linux based server with powerful open-source scanning (Nmap Nikto and Nessus) software. The appliance is updated periodically to stay current with known vulnerabilities and vender patches. Over 65,000 ports scanned and over 18,000 built-in penetration tests automatically interrogate IP based network devices and servers. A database of "findings" is created with severity/ risk levels assigned to help network and system administrators quickly identify and remedy vulnerable ports, operating systems and applications. An Executive Summary and Technical Report are created and findings are reviewed with the client.

Features:

  • Plug-in architecture. Each security test is written as an external plug-in. This way, you can easily add your own tests without hav-ing to read the code of the testing engine.


  • ASL. The Security Scanner includes an Attack Scripting Language, designed to write security tests easily and quickly. Security checks can also be written in C.


  • Up-to-date security vulnerability database. We mainly focus on the development of security checks for recent security holes. Our security checks database is updated on a daily basis, and all the newest security checks are available, including FTP servers and mirrors.


  • Client-server architecture. The Security Scanner is made up of two parts: a server, which performs the attacks, and a client which is the front end. You can run the server and the client on different systems. That is, you can audit your whole network from your personal computer, whereas the server performs its attacks from the SysDefender, which is in the data-center. There are several clients: one for X11, one for Win32 and one written in Java


  • Concurrent Testing. Tests multiple hosts at the same time.


  • Smart service recognition. SysDefender does not believe that the target hosts will respect the IANA assigned port numbers. This means that it will recognize a FTP server running on a non-standard port (31337 say), or a web server running on port 8080


  • Multiples services. Imagine that you run two web servers (or more) on your host, one on port 80 and another on port 8080. When it comes to testing their security, SysDefender will test both of them.


  • Tests cooperation. The security tests performed by SysDefender coordinate with your configuration so that useless tests are not performed. If your FTP server does not offer anonymous logins, then anonymous-related security checks will not be performed.


  • Complete reports: SysDefender will not only tell you what's wrong on your network, but will, most of the time, tell you how to prevent crackers from exploiting the security holes found and will give you the risk level of each problem found (from Low to Very High)


  • Exportable reports: The Unix client can export SysDefender reports as ASCII text, LaTeX, HTML, "spiffy" HTML (with pies and graphs) and an easy-to-parse file format.


  • Full SSL support: SysDefender has the ability to test SSLized services such as https, smtps, imaps, and more. You can even supply SysDefender with a certificate so that it can integrates into a PKI-field environment


  • Smart plug-ins (optional): SysDefender will determine which plugins should or should not be launched against the remote host (for instance, this prevents the testing of SendMail vulnerabilities against Postfix or "optimizations")


  • Non-destructive (optional): If you don't want to take the risk to bring down services on your network, you can enable the "safe checks" option of SysDefender, which will make SysDefender rely on banners rather than exploiting real flaws to determine if a vulnerability is present


  • Independent developers. The SysDefender developers are independent. We will not suppress vulnerabilities because we have a relationship with the authors.
