A Brand New Security Scanning Concept

Hi NT/2000 Pros,

Before we go into the Big Announcement, a reminder. This is the LAST WEEK you can vote for your 'fave' TOOLS at the W2Knews Target Awards 2000. Vote now!
http://www.sunbelt-software.com/targetawards/
Winners will be announced in the W2Knews issue next weekend.

And here is the big announcement. You told us Security was your headache #1. So, I went out and looked at the current market, did my homework and found out some very interesting things. Now I understand better why you say it really IS a major pain:

  • More and more vulnerabilities are found, it's on a steep rise.
  • The amount of your (distributed) machines has mushroomed
  • The attacks get increasingly sophisticated
  • You have less and less time to dedicate to Security
  • It is getting harder and harder to simply keep up, as there are a multitude of (sometimes conflicting) information sources.
  • There is NO centralized, simple way to manage vulnerabilities
  • But your management insists you need to keep things tied down (while increasing exposure via Internet-based applications)
The real problem is that you almost have to be a hacker yourself to be sure no one else can penetrate your networks. But who has time to burn the midnight oil, find out about vulnerabilities, how to exploit them, penetrate your own site, and then plug all the holes found?

Recently I read a survey and it was found that something like 60% of U.S. MIS managers would not hesitate to put Kevin Mitnick on their payroll. (In case you have been creating code locked up in a closet for a few years, Kevin Mitnick is probably the world's most famous hacker who recently came out of prison.) A very recent quote from Mitnick is "What you don't know will hurt you".

The upshot of all this? It would be great if you could have your own hacker on your payroll, who would protect your network. Too bad though, that ain't gonna happen. The next best thing is QualysGuard[tm].

This is the new service that we are introducing. In a nutshell, it's an internet-based artificial intelligence solution that allows you to scan your own systems from the outside in, just like a hacker would, using all known holes and exploits, and then plug the holes you find.

Built and maintained by Security Consultants, (white-hat hackers) and updated d a i l y (!) with the latest exploits found. It's a subscription service, you only use a browser. No installation, training, updates and all the other hassle. Check it out and watch the (web) demo:
http://www.sunbelt-software.com/product.cfm?id=545

I guess you now understand why I'm so excited about QualysGuard. We ran it on our own network but I'm not going to tell you what I found.

Warm regards,

Stu Sjouwerman

  TECH BRIEFING

What is Network Perimeter Defense, and what is Scanning?
(If YOU don't hack your systems, who will?)

DEFINITION:
Network Perimeter Defense is also called Security Auditing and it is a process that identifies network computing equipment and the security vulnerabilities associated with these devices. This info can be used to measure security, manage risks, and eliminate the security vulnerabilities found before unauthorized users can exploit potential security holes.

'Scanning' is what both white-hat and black-hat hackers do. They use a series of both freeware and shareware programs and write their own scripts to attack and penetrate networks. It is a highly specialized kind of activity, but more and more automated tools are being used to hack into sites.

The question really is, if you do not have a process like this in place, when (not if) is some one going to penetrate your network and cause damage. There are a few specialized IT Security consul- tants out there, but they are scarce and expensive. It's up to you to batten down the hatches. Many of you bought STAT and this is a great tool for inside hole-scanning, that you certainly should continue to do. But scanning 'outside-in' was missing up to now, so you should add QualysGuard. Having you own 'attack tool' in place is an essential part of a strong defense.

And being able to scan your own networks, scheduled automatically and get extensive reports on what was found is really a MUST if you want to continue to protect against intruders. Check out:

Operating System Vulnerabilities On The Rise

Everything is getting online, companies are integrating systems with their vendors, interdependencies are created, e-commerce and its next evolutionary step called 'e-business' are rapidly developing.

All this makes strong network security a must. The only way to get there is with robust corporate security programs that include regular network audits for vulnerability assessment and for corrective action. Until now, these audits were typically done by using purchased software or homegrown solutions.

Of course these are initially better than no proactive approach at all, but those solutions often have serious shortcomings that could give you a false sense of security. Some of the drawbacks of a setup like this are:

  • Can be expensive and cumbersome (time consuming) to apply.
  • Results are sometimes difficult to understand.
  • They offer little in the way of risk assessment or scoring.
  • Often lack recommendations for fixing vulnerabilities.
  • They look at the network from the inside out, and thus miss the holes hackers can see.
  • They can become quickly and dangerously outdated as new holes are uncovered constantly, literally at internet speed.
And in the mean time, the amount of vulnerabilities found in the popular OS-es is on the rise. The trends are the same for Linux, Solaris and Windows, and the totals for all three look something like this: (I'm being conservative)
1997: 25
1998: 75
1999: 200
2000: 300
2001: 600

Conclusion: all of the above points to a need for a new approach to security auditing that is:

  • Affordable
  • Extremely easy to deploy and use
  • Effective for Risk Assessment and corrective recommendations
  • ALWAYS up to date on the latest vulnerabilities

    If you run an environment with Windows, (and/or) Linux/Unix I strongly suggest you have a look at the new service we provide:

    Security Specialist Shortage: How do I get to be one?

    Just like MCSE, there are Certifications for Security specialists. And Oh Boy, are they needed! I think this is one of the most urgent needs of corporate IT, and hardest to find. What kinds of Certs are there?

    LevelOne Certification for everyone involved in Security is called GSEC. (GIAC Security Essentials Certified). You can take this live or online.

    LevelTwo Certs for advanced security professionals are:

  • GCIA: GIAC Certified Intrustion Detection Analyst
  • GCIH: GIAC Certified Advanced Incident Handler
  • GCFA: GIAC Certified Firewall Analyst
  • GCIX: GIAC Certified Unix Security Analyst
  • GCNT: GIAC Certified Windows NT Security Analyst

    Around the globe, these GIAC certs mean excellence in security skills. GIAC certified professionals have studied up-to-date material, passed difficult exams, and have proven their mastery through practical demonstrations. If you have the time, this is a really good career move. More at:

    Protecting Your Network Perimeter Is A Continual Process

    The Internet has basically created a perimeter around your corporate network that you need to defend. I have been doing some digging and the most recent data I could get my hands on was the 2000 Computer Crime and Security Survey by the CSI and FBI. Just a few of the highlights of this recent survey:

    • 70% reported serious attacks
    • 42% acknowledged financial loss
    • 59% reported more Internet attacks than internal attacks- this trend is continually up
    • 120% increase in loss last year.
    And all of this is true. Just as an illustration, I just opened up my BlackICE tool, and checked the last few days. I'm on a Cablemodem with a 24 hour connection so this NT WS is a prime target for hackers. Today I had 9 attacks on this box, most of them port probes, and it's only 12:30. Yesterday there were 15. I'm sure you get the point.

    The problem is that your risk of intrusions is a moving target. It would be nice if you could do a vulnerability assessment, plug the holes and be done with it. But no, your network is growing, there are continual machine changes and multiple software installs and upgrades. Each of these can cause one or more new holes to appear.

    On the other hand, the threats multiply too. There are about 4 new vulnerabilities discovered each day, with newly invented exploits to go along with them and there is more and more "hobby hacking". These are also called 'script kiddies' and are usually not very harmful, unless they unleash something that brings your server down.

    The solution to all of this requires an ongoing process. There is no 'cure' for it, there is only a professional approach of managing the vulnerabilities. You have to continually test and retest:

  • points of access
  • potential vulnerabilities
  • problem areas
  • and continue to worry about it.

    In short, you need to institute a (or expand your existing) corporate Vulnerability Management program that will be your Internet Bodyguard. Nothing better than to check out the new QualysGuard that is just that:

    Critical Security Questions and Answers

    I have received some questions that I'll answer in this W2Knews so that everyone has the benefit of them.

    Q1: As a security consultant, I am familiar with products like ISS, Cybercop, Retina, as well as many of the freebie tools like SATAN, SAINT, Nessus, whisker, etc. That said, I am curious what QualysGuard does that is new or different in the way of vulnerability scanners.
    A1: The unique concept is the fact you can subscribe to a service, which will automate the scanning for you, and manages the database of vulnerabilities in pretty much real-time.

    Q2: Is it designed to audit NT or Unix machines (or both)?
    A2: Both, but it finds out what kind of server or device it looks at and then only runs vulnerabilities relative to the device. It has many years of security consulting expertise built in to the AI-engine.

    Q3: Is the scanning technology new?
    A3: It uses known methods to scan and penetrate sites from the outside in. What is new is that it is now available as a managed service that is schedulable and consistent. It also provides a historic database of vulnerabilities found and fixed for upper management purposes.

    Q4: Is the reporting capability considerably different than its competitors?
    A4: I would have to do some more research on this point, as I'm not intimately familiar with the other players in this area. We'll do this and come back on it. Can they send automated emails to warn for critical holes found?

    Q5: The web page says "over 600 vulnerabilities" putting this on par with ISS (who boasts roughly that amount). Given companies like E&Y offering solutions that scan a database of 2200 vulnerabilities, the disparity in numbers begins to stand out.
    A5: The numbers do not tell all. Unfortunately these are used for marketing purposes and it depends entirely on how you count, and what you count. You know the old saying: Lies, damn lies, and statistics. What really is important is the type of holes they test for from the outside, which are different from the things you scan for from the inside out.

    Q6: Is your product available for trial use in any capacity?
    A6: There are three phases. 1: the web-demo, 2: Our reps have a demo account that allows a scan of a live system set up at Qualys. 3: Incidental cases can scan one (1) IP address only but only after signing some legal paperwork.

    Q7: How reliable are these Qualys guys? How do I know that they won't break in my systems?
    A7: Qualys was founded in 1999 with a veteran management team that has its history in Security Consulting. It's Venture Capital backed and has as one of its main investors VeriSign, (VRSN) which is the world's number one provider of Internet trust services.

    Q8: Do I need any kind of equipment on my side at all?
    A8: No, this runs completely from an outside Qualys Internet Server that sits in a secure co-hosting facility.

    Q9: Do I need to be an expert in security to be able to set up and use QualysGuard?
    A9: No, you supply the IP-range you want to scan and get the paperwork signed. From there on out it is clicking on your Favorites button, provide the password and click the SCAN button. The reports show you what was found, how severe it is and how to fix it.

    Q10: I already have a firewall, do I still need QualysGuard?
    A10: Yes. Firewalls are essential to network security but are very complex and often badly configured. QualysGuard tests the effectiveness of your firewall as well as apps such as Web, ftp and mail that are naturally accessible through firewalls. Rule changes can expose your networks, so firewalls need a regular program of "hygiene".

    Q11: I already have an intrusion detection product, why would I need QualysGuard?
    A11: These tools are reactive, you need a proactive approach as when some one is hacking your system, there is a good chance it is already too late.

    Q12: How secure is the QualysGuard solution? How do I know that no one else finds out about the holes in my network?
    A12: The map and scan results are encrypted with 1024-bit protection, as a subscriber you are connected with SSL, there is no archiving (not even backups) and it is completely inaccessible without the password - even by Qualys. All of their machines are located at top-tier hosting facilities.

    Bonus Q13: How long does it take to scan?
    Bonus Answer: Only about 2.5 min per IP, the scanning engine is highly efficient.
